Answer:

3 < x < 8

-2 < x < 4

12 < x ≤ 17

Step-by-step explanation:

x is less than 8 and greater than 3

i.e 3 < x < 8

x is less than 4 and greater than -2

i.e -2 < x < 4

x is greater than 12 and less than or equal to 17

i.e 12 < x ≤ 17

Answer:

-3

Step-by-step explanation:

In order to find the smallest zero, we will have to find out all the zeros of the function.

In case you are wondering what a zero is, it is the x-value or the domain intersections. The points where the parabola intersects the x-axis.

4x² - 8x - 60 = 0

Why zero?

We know that the parabola intersects the x-axis and when it does, the y-value is 0. h(x) is nothing but 'y'.

4(x²-2x-15) = 0 → I took the gcd as 4 and did it accordingly.

x² - 2x - 15 = 0 → Divide on both sides with 4

Now, what multiples to -15 but adds up to -2?

-5 and 3

x² + 3x - 5x - 15 → Grouping the terms

x ( x + 3 ) - 5 ( x + 3 ) → Taking the GCD in both groups

( x - 5 ) ( x + 3 ) = 0

x = 5 , -3

The smallest one out of these zeros is -3.

Answer:

Option C is correct.

Step-by-step explanation:

P(A or B) represents  that event A has occurred or event B has occurred or both events A and B are happening.

We are given P(A or B) = 0.60 or 0.60/100 = 60%

So, Option C The probability that a customer buys either a taco or a drink is 60% is correct.

Answer: Option C

Step-by-step explanation:

For two events A and B, P(A or B) represents the probability that event A occurs, or event B occurs.

In this case, event A represents a customer buys a taco and event B represents a customer buys a drink. We know that

[tex]P (A\ or\ B) = 0.60[/tex]

So this means that the probability that a customer buys either a taco or a drink is 60%

Answer:

Obtuse triangle

Step-by-step explanation:

The longest side of the triangle is 26 in, so that will be the hypotenuse.

By an extension of the Pythagorean theorem:

Where a and b are the legs, and c is the hypotenuse.

Plug in: 3.5² + 25² ₙ 26²

Powers: 12.25 + 625 ₙ 676

Add: 637.25 < 676.

That means that this triangle is obtuse.

Answer:

Obtuse

Step-by-step explanation:

Using law of cosine, we can find the angle between the shorter sides:

c² = a² + b² − 2ab cos C

26² = 25² + 3.5² − 2(25)(3.5) cos C

cos C ≈ -0.221

C ≈ 102.8°

102.8° is greater than 90°, so the triangle is obtuse.

C = 7pi = 21.98 inches

Step-by-step explanation:

The circumference of a circle is given by

C = pi * d

 where d is the diameter

C = pi * 7

If we use 3.14 as an approximation for pi

C = 3.14 * 7

C =21.98 in

Answer:

14 and 18

Step-by-step explanation:

Small number : a

Larger number : a + 4

( a + 4 )^2 - a^2 = 128

a^2 + 8 a + 16    = 128

             8 a        = 128 - 16

                a         = 112 / 8

                a          = 14

And a + 4 = 18

Answer: $139.60  

Step-by-step explanation:

$40 for coming

$29.60 for parts

56 times 1.25 for labor  = 70

70 + 29.6 + 40  =  139.6

The total cost (c) of the repair is given by the sum of the costs for parts, labor, and the service call that is [tex]\$139.60[/tex]

First, we calculate the labor cost. The plumber charged $56 per hour and worked for 1 1/4 hours. To find the total labor cost, we multiply the hourly rate by the time worked:

Labor cost = [tex]hourly \ rate \times \ time \ worked[/tex]

Labor cost =[tex]\$56 \times 1 1/4 hours[/tex]

Labor cost =[tex]\$56 \times (1 + 1/4) hours[/tex]

Labor cost = [tex]\$56 \times (5/4) hours[/tex]

Labor cost = [tex]\$56 \times 1.25 hours[/tex]

Labor cost = $70

Next, we add the cost for parts and the service call to the labor cost to find the total cost:

Total cost (c) = cost for parts + labor cost + service call cost

Total cost (c) = $29.60 + $70 + $40

Total cost (c) = $139.60

Answer: Option A: A vertical line that the line of the graph aproaches but never intecepts it.

Step-by-step explanation:

An asymptote is a graph line that aproaches infinitely to something (in this case a vertical line), but it does not touch it (so never intercepts the graph).

This means that the graph aproaches but never intercepts the line, so the correct answer is A.

Answer:

Neither function A nor function B has an x-intercept.

Step-by-step explanation:

Function A has a y-intercept at (0, 5).

Function B is defined for negative numbers as well as positive numbers, but not for x=0.

These observations eliminate all answer choices but the first one.

The statement that best compares the two functions is; Neither function A nor function B has an x-intercept.

A y-intercept is the point where x = 0. Now, for function A we can see that when x = 0, y = 5. Thus, it has a y-intercept.

However, we are not given the point where y = 0 which is x-intercept. Thus, function A does not have an x-intercept.

Formula for Function B is y = 4/x.

This function does not have an x-intercept because at x = 0, the function is undefined.

Step-by-step explanation:

Final answer:

The volume of a right circular cylinder with a radius of 3 inches and a height of 10 inches is calculated using the formula V = πr²h, which gives 282.74 cubic inches.

Explanation:

To calculate the volume of a right circular cylinder, you can use the formula V = πr²h, where 'V' is the volume, 'r' is the radius, and 'h' is the height of the cylinder. In this instance, the radius (r) is 3 inches, and the height (h) is 10 inches.

Using these values, you can plug them into the formula:

V = π × (3 in)² × 10 in

V = 3.14159 × 9 in² × 10 in

V = 3.14159 × 90 in³

V = 282.74 in³

Therefore, the volume of the cylinder is 282.74 cubic inches.

Answer:

The length of the line segment is 13 units

Step-by-step explanation:

The line segment joining the two points is horizontal since the y co-ordinate is the same.

For a horizontal line, the length of the line segment is simply the difference between the x co-ordinate values.

In this case we have;

7 - (-6) = 7 + 6 = 13

Therefore, the length of the line segment is 13 units

Answer:

13 units

Step-by-step explanation:

We want to find the length  of the line segment with endpoints (-6,-8) and (7,-8).

Observe that, the y-coordinates are the same.

We can quickly use the absolute value method to find the required length.

According to this method the length of the line segment with endpoints (-6,-8) and (7,-8) is the absolute value of the difference between the x-values.

[tex]|7--6|=|7+6|=|13|=13[/tex]

The length of the line segment is 13 units.

Answer:

-8/5

Step-by-step explanation:

The thing that makes lines different from other kinds of curves is their constant rate of change. We call this rate of change slope, and you usually see it represented with the letter m. We measure it as the rate our y-coordinate changes for some amount our x-coordinate changes.

We're given the two points (-1, 4), and (4, -4). From that first point to the second one, our x-coordinate increases by 5, while our y-coordinate decreases by 8, so our change in y is -8 for every 5 in the positive x direction, and we'd write our slope as

m = -8/5

Answer:

together they can plant 175 seeds in 10 minutes

Answer with Step-by-step explanation:

Cara plants 5 seeds in 2 minutes.

⇒ Cara plants 5×5 seeds in 2×5 minutes

⇒ In 10 minutes Cara plant 25 seeds.

Wade plants 3 times as many seeds in half the time as Cara.

⇒ Wade plants 3×5 seeds in 2/2 minutes

i.e. Wade plants 15 seeds in 1 minute.

In 1×10 minutes Wade plants 15×10 seeds

i.e. In 10 minutes Wade plants 150 seeds.

150+25=175

Hence, they can together plant 175 seeds in 10 minutes.

Answer:

the desired equation is y = (-1/5)x - 5.

Step-by-step explanation:

Parallel lines have the same slope.  Here that slope is -1/5.

Let's use the slope-intercept form of the equation of a straight line:

y = mx + b

We know this new line passes through (-10, -3).  Substitute -3 for y in y = mx + b, as well as -10 for x and -1/5 for m:

-3 = (-1/5)(-10) + b and solve for b:

-3 = 2 + b.  Then b = -5, and the desired equation is y = (-1/5)x - 5.

Answer:

the diagonals intersect at right angle i.e. slope of AC = - 1/ slope of BD and

Midpoint of AC = Z₁ is equal to Mid point of BD = Z₂

so, the parallelogram is rhombus.

Step-by-step explanation:

A parallelogram is  a rhombus if diagonals intersect each other at right angle and the diagonals intersect at mid point.

We are given vertices:

A(-3,2)

B(-2,6)

C(2,7)

D(1,3)

The diagonals of the parallelogram will be:

AC and BD.

Slope of AC = y₂ - y₁ / x₂- x₁ where A = (-3,2)  and C = (2,7)

Putting values:

Slope of AC = 7-2/2-(-3) = 5/5  

Slope of AC = 1

Slope of BD = y₂ - y₁ / x₂- x₁ where B = (-2,6) and D = (1,3)

Putting values:

Slope of BD = 3-(6) / 1-(-2) = -3/3

Slope of BD = -1

AS, Slope of AC = - 1/ Slope of BD

So, the diagonals intersect and right angle.

Now finding the mid point Z₁ of AC and Z₂ of BD:

Midpoint of AC = Z₁ = A+C/2

Putting values:

=(-3,2) + (2,7) / 2

= (-1,9)/2

= (-1/2, 9/2)

Mid point of BD = Z₂ = B+D / 2

Putting values:

=(-2,6) + (1,3) / 2

= (-1,9)/2

= (-1/2, 9/2)

Midpoint of AC = Z₁ is equal to Mid point of BD = Z₂ i.e.

Z₁ = Z₂, the diagonals intersect at the same midpoint.

As,

the diagonals intersect at right angle i.e. slope of AC = - 1/ slope of BD and

Midpoint of AC = Z₁ is equal to Mid point of BD = Z₂

so, the parallelogram is rhombus.

At most means it can either equal 20 or be less than 20.

Step-by-step explanation:

[tex]\text{the formula of a distance between two points}\ A(x_1,\ y_1)\ \text{and}\ B(x_2,\ y_2):\\\\|AB|=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\=========================\\\\\text{We have}\ (4,\ 9)\ \text{and}\ (-2,\ 6).\ \text{Substitute:}\\\\d=\sqrt{(-2-4)^2+(6-9)^2}=\sqrt{(-6)^2+(-3)^2}=\sqrt{36+9}=\sqrt{45}\\\\\sqrt{45}=\sqrt{9\cdot5}=\sqrt9\cdot\sqrt5=3\sqrt5[/tex]

The distance between the points (4, 9) and (-2, 6) is approximately 6.71 units.

Identify the coordinates:

Let (x₁, y₁) = (4, 9) and (x₂, y₂) = (-2, 6).

Apply the distance formula:

The distance formula is given by:

d=√[tex]\sqrt{(x_{2}-x_{1} ) ^{2} +(y_{2}-y_{1} )^{2} }[/tex]

Substitute the coordinates into the formula:

d= [tex]\sqrt{((-2)-4)^{2} +(6-9)^{2} }[/tex]²​

Simplify the terms inside the square root:

d=[tex]\sqrt{(-6)^{2} +(-3)^{2} }[/tex]

d=[tex]\sqrt{36+9}[/tex]

d=[tex]\sqrt{45}[/tex]

Simplifying further, we get:

d≈6.71
