Answer:

The value of y = 234 when x = 3.

Step-by-step explanation:

The given model function is y = $10x^3 - 12x$

We need to find the value of y when x = 3.

So, plug in x =3, in the above function, we get

y = $10(3)^3 - 12(3)$

y = 10(27) - 36

y = 270 - 36

y = 234

So, the value of y = 234 when x = 3.

Find the missing lengths of the sides

Ket [755]

ANSWER

The correct answer is C

EXPLANATION

The given triangle is a right triangle. Since two angles are equal, it is a right isosceles triangle.

This implies that, x=8 units.

Using Pythagoras Theorem,

${y}^{2} = {8}^{2} + {8}^{2}$

This implies that:

${y}^{2} = 64 + 64$

${y}^{2} =128$

Take positive square root,

${y} = \sqrt{128}$

${y} = 8 \sqrt{2}$

The correct answer is C

Which ordered pairs lie on the graph of the exponential function f (x) = 3(0.2)^x

photoshop1234 [79]

The ordered pairs which lie on the graph of the exponential function, f(x) = 3(0.2)^x is; Choice A; (0, 3).

<h3>Ordered pair Solution;</h3>

The given exponential function is;

f (x) = 3(0.2)^x

By testing all values; Only the pair; (0, 3) is a solution to the graph of the exponential given.

By testing;

f (0) = 3(0.2)⁰.

Where, (0.2)⁰ = 1 (from indices).

f(0) = 3 × 1 = 3.

Answer:

Step-by-step explanation:

A quarter circle is one fourth of a circle. To find the area of a quarter circle, find the area of the whole circle by using the formula A = pi * r^2 and then divide by 4. To find the perimeter of the quarter circle, find the circumference of the whole circle, divide by 4, and then add the radius twice.
