If the cube root parent function is horizontally stretched by a factor of 4, then translated 5 units right and 3 units up, write

Gala2k [10]

Answer:

The cube root parent function:

f(x) = $\sqrt[3]{x}$

Horizontally stretched by a factor of 4:

g(x) → f(1/4x) = $\sqrt[3]{1/4x}$

Translated 5 units right:

h(x) → g(x - 5) = $\sqrt[3]{1/4x - 5}$

Translated 3 units up:

k(x) → h(x) + 3 = $\sqrt[3]{1/4x - 5} + 3$

If you start with Malvin’s age, take half of it, increase that result by 5, then divide by 3, and finally double that, you get 8

Kisachek [45]

Answer:

24 years old

Step-by-step explanation:

Let Malvin's age be x.

x / 2
x / 2 + 5 = 5x / 10 [ By taking the L.C.M.]
( 5x / 10 ) * ( 1 / 3 ) = 5x / 30 [ Multiply with the reciprocal of 3 ]
( 5x / 30 ) * 2 = 5x / 15

Now let's solve the equation,

5x / 15 = 8

5x = 8 * 15

5x = 120

x = 120 / 5

x = 24

Therefore, Malvin is 24 years old.

Use Julia’s work and finish finding the areas of the faces what is the surface area of the rectangular pyramid

hoa [83]

Answer:

The surface area of the rectangular pyramid is $SA=109.50\ m^{2}$

Step-by-step explanation:

we know that

The surface area of the rectangular prism is equal to the area of the rectangular base plus the area of the four triangular faces

$SA=(8)(5)+2[14.75]+2[\frac{1}{2}(8)(5)]$

$SA=40+29.50+40$

$SA=109.50\ m^{2}$
