The answer is true, 4 x 4 = 16 and 5 x 5 = 25. Therefore anything from 4-5 x 4-5 will be between 16-25. Examples 4.2 x 4.8 = 20.16 No two numbers will be less than 16 or greater than 25. If this helps please hit thanks and branliest :)

Please help with my algebra homework and explain if you can : v= pi/3 rsquared h

Tanzania [10]

To isolate the variable means to have it by itself on one side of the equation, where the variable equals an expression.

To isolate $h$ , we will need to remove the variables and other terms "connected" to the $h$ variable:

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

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

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

By dividing terms "connected" to our $h$ variable, we have isolated it one side of the equation.

Population grows.

Gnom [1K]

Population are often modelled by exponential functions

The population will reach 1000000 people after 26.5 years

The population function is given as:

$P(x) = 692600 \times 1.014^x$

When the population reaches 1000000 people, we have:

P(x) = 1000000

So, the equation becomes

$1000000 = 692600 \times 1.014^x$

Divide both sides by 692600

$1.444=1.014^x$

Take logarithm of both sides

$log(1.444)=log(1.014)^x$

Apply logarithm to both sides

$log(1.444)=xlog(1.014)$

Make x the subject

$x = \frac{log(1.444)}{log(1.014)}$

Solve the logarithms of 1.444 and 1.014

$x = \frac{0.15957}{0.00603}$

Divide

$x = 26.5$

The value of x, is the number of years the population reaches 1000000 people.

Hence, the population will reach 1000000 people after 26.5 years
