1 answer:
forsale [732]2 years ago
7 0

Answer: Yes

If I remember correctly, I believe these ordered pairs indicate a function, as there is exactly 1 output for every input (i.e., (output, input)). If there were 2 inputs of the same number, that'd make this relation not a function.

Consider the graph of the quadratic function. Which interval on the x-axis has a negative rate of change?
Gre4nikov [31]

The average rate of change is defined as:

AVR = \frac{f(x2)-f(x1)}{x2-x1}

For AVR to be negative, it must comply with:

x2 - x1> 0

f (x2)

Therefore, we observe that the interval that fulfills these conditions is the whole interval to the right of the parabola.

Among the options given, this interval is:

1 to 2.5

Answer:

An interval on the x-axis that has a negative rate of change is:

D. 1 to 2.5

Surface Area of Cylinders - Item 1175
mylen [45]

The surface area is 47.1 sq in.

Step-by-step explanation:

Given,

The height (h) of the coin (cylinder shaped) = 5 inches

The radius (r) = 1.5 inches

To find the surface area of the coin.

We need to find the lateral surface area of the coin.

Formula

The surface area of the coin of radius r and height h is 2πrh.

Now,

Putting the value of h and r and π=3.14 we get,

Area = 2×3.14×1.5×5 sq inches

= 47.1 sq in

Hence, the surface area is 47.1 sq in.

Question 3 (1 point)
lana66690 [7]

Answer: The area of the new parallelogram is multiplied by 18

Step-by-step explanation: Let the base and the height of the original parallelogram be ' x '

Base of the parallelogram = x

Height of the parallelogram = x

Area of parallelogram = l × b = lb

= x × x = x²

∴ Area of the original parallelogram = x²

∴ The base is multiplied by 3 = 3x

The height is multiplied by 6 = 6x

∴ Area of new parallelogram = 3x × 6x = 18x²

∴ The area of the new parallelogram is multiplied by = 18x²/ x²

= 18
