Given that f(x) = x2 + 8x + 15 and g(x) = x + 5, find f(x) · g(x) and express

sukhopar [10]

The result of $f(x) \times g(x)$ is $x^3 + 13x^2+ 55x+ 75$

<h3>Composite functions</h3>

Composite functions are functions that are gotten by combining multiple functions

<h3>The functions</h3>

The functions are given as:

$f(x) = x^2 + 8x + 15$

$g(x) = x+5$

To calculate f(x) * g(x), we have:

$f(x) \times g(x) = [x^2 + 8x + 15] \times [x + 5]$

Expand the above expression

$f(x) \times g(x) = x^3 + 8x^2 + 15x + 5x^2 + 40x + 75$

Collect like terms

$f(x) \times g(x) = x^3 + 8x^2 + 5x^2+ 15x + 40x + 75$

Evaluate the like terms

$f(x) \times g(x) = x^3 + 13x^2+ 55x+ 75$

Hence, the result of $f(x) \times g(x)$ is $x^3 + 13x^2+ 55x+ 75$

Parallelogram PARL is similar to parallelogram WXYZ. If AP = 15, PL = 40, and WZ = 120, find the value of c .50 110 6 45

vova2212 [387]

Answer:

Option D. c = 45 will be the answer.

Step-by-step explanation:

In the figure attached there are two similar parallelograms PARL and WXYZ.

In which AP = 15, PL = 40, WZ = 120 and WX = c

By the property of similarity, corresponding sides of the given parallelograms will be in the same ratio.

$\frac{PL}{WZ}=\frac{PA}{WX}$

$\frac{40}{120}=\frac{15}{c}$

c = $\frac{15\times 120}{40}$ [By cross multiplication]

c = 45

Therefore, Option D. c = 45 will be the answer.

Which equation is the inverse of 2(x - 2)^3=8(7+y)

irina1246 [14]

Answer:

$\large\boxed{y=2\pm\sqrt{28+4x}}$

Step-by-step explanation:

$2(x-2)^2=8(7+y)\\\\\text{exchange x to y, and vice versa:}\\\\2(y-2)^2=8(7+x)\\\\\text{solve for y:}\\\\2(y-2)^2=(8)(7)+(8)(x)\\\\2(y-2)^2=56+8x\qquad\text{divide both sides by 2}\\\\(y-2)^2=28+4x\iff y-2=\pm\sqrt{28+4x}\qquad\text{add 2 to both sides}\\\\y=2\pm\sqrt{28+4x}$

mary will spin the spinner below 150 times. about how many times should mary expect the spinner to land on a number greater than

irga5000 [103]

Answer:

56 times (This is still assuming 1 isnt an option)

Step-by-step explanation:

0,2,3,4,5,6,7,8

There are 8 options, 3 of which are greater than 5

3/8

3/8 = x/150

3*150 = 450

8 * x = 8x

8x = 450

450/8 = 56.25

56 times
