A tank has 15 gallons of water in it when water begins draining from the tank. (Recall that water weighs 8.345 pounds per gallon.)
Define a function f that determines the number of gallons of water in the tank, f ( w ) , in terms of the number of pounds of water that have drained from the tank since the tank started draining, w .
Answer:
[tex]f(w) = 15 - \frac{w}{8345}[/tex]
Step-by-step explanation:
Water begins draining from a tank when the tank has 15 gallons of water in it.
Now, if we define f(w) as a function that represents the number of gallons of water remains in the tank after w pounds of water that have drained from the tank since the tank started draining, then the function can be represented as
[tex]f(w) = 15 - \frac{w}{8345}[/tex]
Since, w pounds of water is equivalent to [tex]\frac{w}{8345}[/tex] gallons of water. (Answer)
(Recall that water weighs 8.345 pounds per gallon.)
The function f should be defined is [tex]f(w) = 15 - \frac{w}{8345}[/tex]
Important information:A tank has 15 gallons of water in it when water begins draining from the tank. (Recall that water weighs 8.345 pounds per gallon.)
Function:Since we have to defined the function so it is f(w) that shows the number of gallons of water remains in the tank after w pounds of water.
So, the function should be [tex]f(w) = 15 - \frac{w}{8345}[/tex]

Step-by-step explanation:
the function h=14t²+56t+60 represents the height of an object that is launched directly up into the air, where h represents the height in feet of the object and t represents time in seconds
What is the maximum height in feet of the object?
How long will it take the object to reach its maximum height?
Answer:
It will take the object 2 seconds to reach the maximum height.
Step-by-step explanation:
The original equation is [tex]h=-14t^2+56t+60[/tex].
The object reaches the maximum height when derivative of [tex]h[/tex] is zero
[tex]\frac{dh}{dt}=0[/tex]
So let us take evaluate the derivative of [tex]h[/tex]
[tex]\frac{dh}{dt} =\frac{d}{dt} (-14t^2+56t+60)=\frac{d}{dt} (-14t^2)+\frac{d}{dt}(56t)+\frac{d}{dt} (60)[/tex]
[tex]=-28t+56[/tex]
this must be equal to 0:
[tex]-28t+56=0[/tex]
[tex]t=\frac{-56}{-28}[/tex]
[tex]\boxed{ t=2}[/tex]
It will take the object 2 seconds to reach the maximum height.
What is the measure of angle x
Enter your answer in the box
x = 83°
Solution:
The reference image to the answer is given below.
Sum of the adjacent angles in a straight line = 180°
⇒ ∠1 + ∠2 + ∠3 = 180° (Refer image)
⇒ 56° + ∠2 + 41° = 180°
⇒ 56° + 41° + ∠2 = 180°
⇒ 97° + ∠2 = 180°
⇒ ∠2 = 180° – 97°
⇒ ∠2 = 83°
In the given image ∠5 and ∠2 are vertically opposite angles.
Vertical angle theorem:
Vertically opposite angles are equal.
⇒ ∠5 = ∠2
⇒ x = ∠2
⇒ x = 83°
Hence the measure of angle x is 83°.
Which choice shows the coordinates of C’ if the trapezoid is reflected across the y-axis?

How does reflection across axis work?When a graph is reflected along an axis, say x axis, then that leads the graph to go just in opposite side of the axis as if we're seeing it in a mirror.
If you study it more, you will find that its symmetric, thus each point is equidistant from the axis of reflection as that of the image of that point.
Thus, if you're reflecting a point (x,y) along x axis, then its x
abscissa will stay same but y
ordinates will negate. Thus (x,y) turns to (x, -y)
Similarly, if you're reflecting a point (x,y) along y axis, the resultant image of the point will be (-x,y)
Given;
On a coordinate plane, trapezoid A B C D has points (2, 1), (3, 5), (5, 3) and (3, 1).
Now,When a point is reflected across the y-axis, the rule is:
(x,y)→ (-x,y)
C (5.3)= C' (-5,3)
Therefore, the reflection on C will be C (5.3) C' (-5,3).

Reflect the parent function over the x-axis, and translate it 8 units to the right.
Reflect the parent function over the x-axis, and translate it 8 units to the left.
Answer:
Reflect the parent function over the x-axis, and translate it 8 units to the left.
Step-by-step explanation:
The given function is
[tex]y = - \sqrt{x + 8} [/tex]
The parent function is
[tex]y = \sqrt{x} [/tex]
Since there is a negative multiply the transformed function, there is a reflection in the x-axis.
Since 8 is adding, within the square root, there is a horizontal translation of 8 units to the left.
Therefore to graph the given function, reflect the parent function over the x-axis, and translate it 8 units to the left.
Take the reflection of the graph about the x-axis and then translate the graph of the function by 8 units in the left direction and this can be determined by using the rules of transformation.
Given :
Function -- [tex]\rm y = - \sqrt{x+8}[/tex]
The following steps can be used in order to determine the correct statement:
Step 1 - The parent function is given below:
[tex]\rm y = \sqrt{x}[/tex]
Step 2 - Now, draw the graph of the parent function.
Step 3 - Take the reflection of the graph about the x-axis. So, the function becomes:
[tex]y =- \sqrt{x}[/tex]
Step 4 - Now, translate the graph of the function obtained in the above step by 8 units in the left direction. So, the function becomes:
[tex]y = -\sqrt{x+8}[/tex]

The age of Noelle’s dad is 6 less than 3 times Noelle’s age. The sum of their ages is 74 . Find their ages.
Answer:
The age of Noelle's dad is 54 years and that of Noelle is 20 years.
Step-by-step explanation:
Let the age of Noelle's dad is x years and that of Noelle is (74 - x) years.
{Since, the sum of their ages is 74}
Now, given that the age of Noelle's dad is 6 less than 3 times Noelle's age.
So, 3(74 - x) - 6 = x
⇒ 4x = 222 - 6 = 216
⇒ x = 54
So, the age of Noelle's dad is 54 years and that of Noelle is (74 - 54) = 20 years. (Answer)

Find the roots of f(x)=x^2+10x−96
Question 6 options:
x=8 or x=−12
x=6 or x=−16
x=−6 or x = 16
x =8 or x =12
Answer:
the answer is x=6 or x=-16
The correct answer is x = 6 or x = -16.
To find the roots of the quadratic function f(x) = x2 + 10x - 96, we need to solve the equation x2 + 10x - 96 = 0 using the quadratic formula.
Using the quadratic formula, x = (-b ± √(b2 - 4ac)) / 2a, where a = 1, b = 10, and c = -96, we get x = 6 or x = -16 as the roots of the function f(x).
Therefore, the correct answer is x = 6 or x = -16.
20. Math and Science There are 6 pure

orange or red. What fraction of the pure
spectral colors can bees see?
2/1 frptrhgqhgr4tjtfix jxcfh8u5t8ofszYI7wyt439tfy7efgy5g
Final answer:
Bees can see 4 out of the 6 pure spectral colors, which simplifies to the fraction 2/3 after removing the 2 colors they cannot see, orange and red.
Explanation:
The question involves calculating a fraction, which is a basic mathematical concept. We are told there are 6 pure spectral colors: red, orange, yellow, green, blue, and violet. Bees cannot see orange or red, so we must find out what fraction of the 6 pure spectral colors bees can see. We subtract the 2 colors bees can't see (orange and red) from the total of 6, leaving us with 4 colors they can see which are yellow, green, blue, and violet.
To express this as a fraction, we take the number of colors bees can see (4) and place it over the total number of pure spectral colors (6). Therefore, the fraction of pure spectral colors that bees can see is 4/6. This fraction can be simplified by dividing both the numerator and the denominator by their greatest common divisor, which is 2. Thus, the simplified fraction is 2/3.
