Answer:

5 + 4 x 2 - 6

Step-by-step explanation:

An expression is just a sentence in math, so you can just write out the numbers and symbols.

An equation is like an expression, but an equation has to have an = sign. Equation -- equals, get it?

What is the exact volume of the cone

Travka [436]

Answer:

V = $\frac{400}{3}$ $\pi$

Step-by-step explanation:

Volume of a cone is:

$V = \pi r^{2} \frac{h}{3}$

Substitute values given:

$V = \pi (5^{2} )(\frac{16}{3})$

$V = \pi (25)(\frac{16}{3} )$

V = $\pi \frac{400}{3}$

V = $\frac{400}{3}$ $\pi$

Y is directly proportional ( x+2)² <br> when x = 8 y= 250 <br> find y when x = 4

sladkih [1.3K]

Answer:

y=90 when x=4

Step-by-step explanation:

We are given that

$y\propto (x+2)^2$

When x=8 and y=250

We have to find the value of y when x=4

$y=k(x+2)^2$

Where k= Proportionality constant

Substitute the values

$250=k(8+2)^2$

$250=100k$

$k=\frac{250}{100}$

$k=5/2$

Now, substitute x=4 and k=5/2

Then, we get

$y=\frac{5}{2}(4+2)^2$

$y=\frac{5}{2}\times 36$

$y=90$
