Find the product. a^4(3a ^2 - 2a + 1)

Vikki [24]

a⁴(3a² - 2a + 1)

We just have to multiply each term inside the parentheses by a⁴ .

 a⁴(3a² ) = 3a⁶

 a⁴( - 2a ) = -2a⁵

 a⁴( 1) = a⁴

Now, just addum up : 3a⁶ - 2a⁵ + a⁴

If - 7 = 9 + x, then -3x + 5 = ?

Vikentia [17]

Answer:

Step-by-step explanation:

At first,

- 7 = 9 + x

By subtracting 9 from both sides, we get

-7-9=9+x-9

-16=x

Now,

By substituting the value of x in -3x + 5 , we get

-3x + 5

-3×(-16)+5

statistical models predict that price p( in dollars) of a new smartphone will change according to the function p=900-4t^2. where

Gre4nikov [31]

we are given

$p=900-4t^2$

where

price p( in dollars) of a new smartphone

t is the number of months since January

now, we can solve for t

step-1:

Add both sides by 4t^2

$p+4t^2=900-4t^2+4t^2$

$p+4t^2=900$

step-2:

Subtract both sides by p

$p+4t^2-p=900-p$

$4t^2=900-p$

step-3:

divide both sides by 4

$\frac{4t^2}{4} =\frac{900-p}{4}$

$t^2=\frac{900-p}{4}$

$t^2=225-0.25p$

step-4:

Take sqrt both sides

$\sqrt{t^2} =\sqrt{225-0.25p}$

$t=\sqrt{225-0.25p}$

so, we get

$t=\sqrt{225-0.25p}$ ..............Answer
