Radius = 8 ft; Height = 7 ft<br> What is the volume

Goshia [24]

Answer:

volume = 1,407.4 cubic feet

Step-by-step explanation:

Radius = 8 ft

Height = 7 ft

volume = area x height

area = π r^2

= 3.14 x 8^2

= 200.96

volume = 200.96 x 7

= 1,407.4 cubic feet

If y/5+8=7, what is the value of y/5-2

Andrei [34K]

"<span>y/5+8=7, what is the value of y/5-2?" Simplify the first equation:

y/5 = 7 - 8, or -1, so y/5 = -1, or y = -5.

Then y/5 - 2 equals -5/5 - 2, or -3.</span>

L 5.2.3 Quiz: Two-Variable Systems: Substitution

Misha Larkins [42]

Answer:

We get x=3 and y=21

The ordered pair will be: (3,21)

Step-by-step explanation:

We need to use the substitution method to solve the system of equations.

$y = 10x-9\\y = x + 18$

For substitution method we substitute the value of x or y from one equation to other.

Let:

$y = 10x-9--eq(1)\\y = x + 18--eq(2)$

Putting value of y from equation 2 into equation 1

$y=10x-9\\Put\:y=x+18\\x+18=10x-9\\x-10x=-9-18\\-9x=-27\\x=\frac{-27}{-9}\\x=3$

So, we get value of x=3

Now, for finding value of y, We substitute the value of x

Find value of x from equation 2

$y=x+18\\x=y-18$

Now, putting value of x in equation 1

$y=10x-9\\Put\:x=y-18\\y=10(y-18)-9\\y=10y-180-9\\y-10y=-189\\-9y=-189\\y=\frac{-189}{-9}\\y=21$

So, we get value of y=21

So, We get x=3 and y=21

The ordered pair will be: (3,21)

If f(x)= x squared and g(x)=2x^3- x squared, find f(x)-g(x).

tankabanditka [31]

Answer:

$f(x)-g(x)=2x^2(1-x)$

Step-by-step explanation:

Given that,

$f(x)=x^2\\\\g(x)=2x^3-x^2$

We need to find the value of f(x)-g(x).

Put the values of f(x) and g(x). So,

$f(x)-g(x)=x^2-(2x^3-x^2)\\\\=x^2-2x^3+x^2\\\\=2x^2-2x^3\\\\=2x^2(1-x)$

So, the value of f(x)-g(x) is equal to $2x^2(1-x)$ .
