What are the intercepts of the graphed function?
x- intercept = (-1,0)
y- intercept = (-3,0)
x- intercept = (0,1)
y- intercept = (0,-3)
x- intercept = (0,-1)
y- intercept = (-3,0)
x- intercept = (-1,0)
y- intercept = (0,-3)
Answer:
x-intercept = (-1,0)
y-intercept = (0,-3)
Step-by-step explanation:
The intercepts of a function are points where the graph intersects the x-axis or y-axis. The valid x-intercepts from the provided list are (-1,0) and (0,-1), and the valid y-intercepts are (-3,0) and (0,-3). The points (0,-1) and (0,-3) serve both as an x and y-intercept.
Explanation:The intercepts of a graphed function are the points at which the graph intersects the x-axis or the y-axis. These are key in understanding the behaviour of a function.
The x-intercept is the point where the graph cuts the x-axis and has a coordinate in the form (a, 0), where 'a' is a real number. In your list of intercepts, the valid x-intercepts are (-1,0) and (0,-1). Noting that (0,-1) is a special case where it also serves as a y-intercept.
In contrast, the y-intercept is the point where the graph intersects the y-axis. It has a coordinate in the form (0, b), where 'b' is a real number. From your list, the valid y-intercepts are (-3,0) and (0,-3). Similarly to the above, (0,-3) is a special case where it also serves as an x-intercept.

On your own paper, graph the coordinates of quadrilateral ABCD.
● A(-3, 0)
● B(2, 4)
● C(6, -1)
● D(1, -5)
A) Identify what type of quadrilateral ABCD will be and give an explanation of your response. You must also justify it algebraically by showing your work to support your response.
B) What is the perimeter and area of quadrilateral ABCD?
Answer:
A) Square
B) Perimeter: 4sqrt(41) units
Area: 41 units²
Step-by-step explanation:
AB and CD are parallel because both have the same gradient:
AB: (-3-2)/(0-4) = 5/4
CD: (6-1)/(-1--5) = 5/4
AD and BC are parallel because both have the same gradient:
AD: (-3-1)/(0--5) = -4/5
BC: (6-2)/(-1-4) = -4/5
Since (5/4) × (-4/5) = -1
All angles are 90 (Perpendicular)
Lengths
CD = AB = sqrt[(-3-2)²+(0-4)²] = sqrt(41)
BC = AD = sqrt[(6-2)²+(-1-4)²] = sqrt(41)
Therefore all sides are equal in length
Hence it's a square
Perimeter = 4s = 4sqrt(41) units
Area = s² = [sqrt(41)]² = 41 units²
What do birds such as eagles and hawks need energy for?
A) flying
B) breathing
C) digesting food
D) all of the above
Birds need energy for flying, breathing, and digesting food. Because of their high metabolism and active lifestyles, all of these processes are crucial for their survival and require substantial energy.
Explanation:Birds such as eagles and hawks need energy for a variety of activities essential to their survival. The correct answer to what they need energy for is D) all of the above.
These activities include flying, which is a highly energy-intensive activity requiring strong and efficient flight muscles; breathing, because birds have a unique respiratory system adapted for high levels of oxygen intake to support their active metabolisms; and digesting food, since birds have higher metabolic rates than humans, they need to digest their food quickly and eat often to maintain their energy levels.
The digestive process itself also consumes energy as nutrients from food are transformed into usable energy through biochemical reactions.
Final answer:
Eagles and hawks need energy for flying, breathing, and digesting food. Flying requires significant amounts of oxygen and energy due to the bird's efficient but energy-demanding flight muscles. Breathing and digestion are also energy-consuming processes that support the bird's active metabolism and need for frequent food intake.
Explanation:
Eagles, hawks, and other birds require energy for several key activities which are essential for their survival. The energy needs of birds like eagles and hawks encompass flying, breathing, and digesting food. Flying is an activity that demands a great deal of energy since birds need to be light to fly and have powerful flight muscles, making their digestive systems more rapid compared to humans.
Breathing is another crucial activity where birds have adapted a highly efficient respiratory system that enables them to take in the necessary oxygen to support their high metabolic rates. This is especially important because flying consumes a tremendous amount of energy, and birds need to eat often to maintain energy levels due to their quick digestion.
Lastly, digesting food also requires energy, as digestion is the process of breaking down food and transforming nutrients into energy through a series of biochemical reactions. Because birds digest their food quickly, they need to eat greater amounts of food more frequently to meet their high energy demands, which are raised even higher because birds have smaller surfaces to lose heat than humans.
A plot of land has an area of 33.75 square feet. Jackson wants to put a 4-foot by 4-foot shed on the land. He can only do this if the height of the trapezoid is at least 4.5 feet. What is the height of the trapezoid?
Answer:
the height of the trapezoid is 4.5 feet.
Step-by-step explanation:
i got it right
The height of the trapezoid cannot be determined from the information given in the problem. The areas and base lengths or the lengths of the diagonals of the trapezoid are required to determine its height.
Explanation:The question seems to be a bit conflicted. First, if we look at the information given, the plot of land with an area of
33.75 square feet
is the space for the trapezoid, not its height. The shed, with its dimensions, will take up 16 square feet. But putting a shed on the trapezoid or relating this to the height of the trapezoid doesn't seem to connect. The
height of the trapezoid
is not something we can determine with the information given. To determine the
height of a trapezoid

jordan purchased 30 bags of candy for $12. At that rate how many bags of candy can he purchase for $8
Answer:
45 bags of candy
Step-by-step explanation:
The first thing is to calculate the money Jordan has, we know that by multiplying the number of bags by their price, that is:
30*12 = 360
I mean, he's got $360, now with this money he wants to buy $8 bags, so it would be
360/8 = 45
That means I could buy 45 bags of candy if they cost $8
Jordan can purchase 20 bags of candy for $8.
Jordan purchased 30 bags of candy for $12. At that rate, to find out how many bags of candy he can purchase for $8, we first calculate the cost per bag of candy by dividing the total cost by the number of bags purchased. This gives us a rate of $0.40 per bag of candy ($12/30 = $0.40). To determine how many bags of candy Jordan can purchase for $8, we then divide $8 by the cost per bag, which is $0.40.
Calculating, $8/$0.40 = 20 bags of candy. Thus, for $8, Jordan can purchase 20 bags of candy at the same rate.

Order each set of integers from greatest to least
(8, 43, -25, 12, -14, 3)
(-8, 32, 55, -32, -19, -3)
(-100, -89, -124, -69, -52)
(6, 17, -20, -19, 26)
The ordered sets are: (43, 12, 8, 3, -14, -25), (55, 32, -3, -8, -19, -32), (-52, -69, -89, -100, -124), and (26, 17, 6, -19, -20).
To order each set of integers from greatest to least, we start by identifying the largest integer in each set and then follow with the next largest until we reach the smallest integer. Let's order the provided sets one by one:
For the set (8, 43, -25, 12, -14, 3), the order from greatest to least is: 43, 12, 8, 3, -14, -25.
The set (-8, 32, 55, -32, -19, -3) ordered from greatest to least is: 55, 32, -3, -8, -19, -32.
Ordering the set (-100, -89, -124, -69, -52) from greatest to least gives us: -52, -69, -89, -100, -124.
Finally, the set (6, 17, -20, -19, 26) ordered from greatest to least is: 26, 17, 6, -19, -20.
By comparing the positive and negative integers, we determine their placement in the sequence from greatest to smallest.

Describe what this graph would look like. Where would it start? How would the slope be counted out?
Answer:
The equation is in the form y=mx+b, where m=slope, b=y-intercept.
The y-intercept is 35: so the line goes through the y-axis at (0,35).
The slope is 25: so we need to count out the slope as rise over run, or 25 up and 1 to the right, starting from the y-intercept.
The parallelogram shown below has an area of 140 units^2. The base is twelve and the side is 10 help this is so hard.
Answer:
height = 11.67 units
Step-by-step explanation:
A parallelogram is a quadrilateral with 2 pairs of parallel sides. This means opposites sides are parallel to each other. Opposite angles and sides are congruent.
From your question the base of the parallelogram is given as 12 units and the sides is 10 units. The area of the parallelogram is given as 140 units². What is left is the height of the parallelogram.
Using the formula for finding the area of a parallelogram, the height can be found.
area of a parallelogram = base × height
base = 12 units
height = ?
area = 140 unit²
area of a parallelogram = base × height
let
h = height
140 = 12h
divide both sides by 12
h = 140/12
h = 11.6666666667 units
height = 11.67 units
On a survey, 3 out of every 8 band members prefer listening to jazz music.
Based on the survey, how many out of 240 band members would prefer listening to jazz music?
A. 65
B. 90
c. 144
d. 175
Answer:
B.) 90
Step-by-step explanation:
Since the ratio is 3:8, the fraction would look something like the following.:
[tex]\frac{3}{8} =\frac{?}{240}[/tex]
We know that there are 240 band members in this scenario. What do you multiply 8 by to get 240? 30.
[tex]\frac{3*30}{8*30} =\frac{90}{240}[/tex]
To solve the problem, we set up a proportion, 3/8 = x/240. Solving for 'x', we find that 90 out of 240 band members would prefer listening to jazz music, so the correct answer is B (90).
Explanation:This problem concerns proportions. In the survey, it is stated that 3 out of 8 band members preferred listening to jazz. To find out how many out of 240 would prefer jazz, we set up and solve a proportion. Our proportion is 3/8 = x/240, where 'x' is the number of band members we need to find.
To solve for 'x', we cross-multiply 3*240 = 8x. This gives 720 = 8x. Then divide by 8, and we get x = 90. So, 90 out of 240 band members would prefer listening to jazz music.

By what percent will the product of two numbers decrease if one of them is decreased by 20% and the other is decreased by 60%?
Answer:
We have:
P1 = a x b
If a decreases by 20% and b decreases by 60%, then we have:
P2 = a x (100 - 20)/100 x b x (100 - 60)/100
= a x 80/100 x b x 40/100
= a x b x 8/25
=> P1 - P2 = ab - (8/25)ab = (17/25)ab
=> If a decreases by 20% and b decreases by 60%, product of a and b would decrease 17/25 = 0.68%

Brandon is pulling a desk to the right with a force of 26.00 N. The force of friction to the left is 3.00 N.
a. Calculate the net force:
b. If the desk accelerates at 2.0 m/s2, find the mass of the desk.
Step-by-step explanation:
first and foremost start off with a proper FBD (I drew in the forces and acceleration just to refer back to it quicker, assume right and up are positive)
a) F net = Forces aiding the movement - forces opposing
if the box is sliding to the right then we've got
Fnet = 26 + (-3)
[notice how I wrote that they're both being added because they're vector forces]
Fnet = 23 N
b) using Newton's second law of motion, F = ma, we can find the mass
Fnet = ma
rearrange for mass
M = Fnet/a
M = 23 N / 2.0 ms^-2
M = 11.5 Kg
The net force is 23.00 N to the right. The mass of the desk is 11.5 kg.
Explanation:a. Calculate the net force:
The net force is the vector sum of all the forces acting on an object. In this case, the force of Brandon pulling the desk to the right is 26.00 N, and the force of friction to the left is 3.00 N. Since the friction force is in the opposite direction of the pulling force, we subtract it. Therefore, the net force is 26.00 N - 3.00 N = 23.00 N to the right.
b. If the desk accelerates at 2.0 m/s2, find the mass of the desk:
The equation for calculating the net force on an object is F = ma, where F is the net force, m is the mass, and a is the acceleration. Rearranging the equation to solve for mass, we have m = F/a. Plugging in the values, mass = 23.00 N / 2.0 m/s2 = 11.5 kg.

In Triangle WXZ
105+43+[tex]\angle WZX[/tex]=180 (Sum of Angles in a Triangle)
148+[tex]\angle WZX[/tex]=180
[tex]\angle WZX[/tex]=180-148
[tex]\angle WZX[/tex]=32 degrees
Since |XY|//|WZ| (parallel to)
[tex]\angle WZX[/tex]=[tex]\angle YXZ[/tex] (Alternate Angles)
Therefore:
[tex]\angle YXZ[/tex]=32 degrees
Which triangle can be solved using the law of sines?
The triangle C can be solved using the law of sines.
What is the law of sines?
'The law of sine or the sine law states that the ratio of the side length of a triangle to the sine of the opposite angle, which is the same for all three sides.'
According to the given problem,
We know,
Law of sines = [tex]\frac{a}{sinA} = \frac{b}{sinB} = \frac{c}{sinC}[/tex]
In triangle C,
Third angle = 180 - ( 70 + 30 )
= 180 - 100
= 80°
⇒ [tex]\frac{10}{sin30 }= \frac{b}{sin70} =\frac{c}{sin80}[/tex]
⇒ [tex]\frac{10}{sin30}= \frac{b}{sin70}[/tex]
⇒ 20 × 0.9396 = b
⇒ b = 18.8 m
