Given: F(x) = x + 2 and G(x) = 3x + 5<br><br> (F*G) (x) =

vovangra [49]

Answer:

$\boxed{(f \times g)(x) = 3 {x}^{2} + 11x + 10}$

Given:

$f(x) = x + 2 \\ \\ g(x) = 3x + 5$

To Find:

$(f \times g)(x) = f(x) \times g(x)$

Step-by-step explanation:

1. The triangles above are similar. What is the ratio (larger to smaller) of the perimeters? (1 point)

eimsori [14]

Answer:

Ratio = 5/3

The ratio (larger to smaller) of the perimeters is 5/3

Step-by-step explanation:

Attached is an image of the two triangles.

Since both triangles are similar, the ratio of their perimeter is equal to the ratio of each similar sides.

Ratio = P1/P2 = S1/S2

Similar side for triangle 1 S1 = 15ft

Similar side for triangle 2 S2 = 9ft

Substituting the values;

Ratio = 15ft/9ft = 5/3

Ratio = 5/3

The ratio (larger to smaller) of the perimeters is 5/3

Y varies directly as cube root of

andreev551 [17]

Step-by-step explanation:

Y varies directly as cube root of x is written as

y = k³√x

where k is the constant of proportionality

<h2>A).</h2>

when y = 3

x = 27

We have

$3 = k \sqrt[3]{27}$

But ³√27 = 3

That's

3 = 3k

Divide both sides by 3

k = 1

<h3>The value of the constant is 1</h3>

<h2>B).</h2>

The value of the relationship is

<h2> $y = \sqrt[3]{x}$ </h2>

<h2>C).</h2>

When x = 8

We have

<h2> $y = \sqrt[3]{8}$ </h2>

<h3>y = 2</h3>

Hope this helps you
