Answer:

first option

Step-by-step explanation:

If ( x + h) is a factor of f(x) then f(- h) = 0 , then

If (x + 1) is a factor of f(x) then f(- 1) = 0

f(- 1) = 7 $(-1)^{4}$ - 5(- 1)³ - 10(- 1)² + 2(- 1)

= 7(1) - 5(- 1) - 10(1) - 2

= 7 + 5 - 10 - 2

= 12 - 12

= 0

Since f(- 1) = 0 then (x + 1) is a factor of f(x)

What is the simplest form of the radical expression?

BaLLatris [955]

I believe the equation is
$4 \sqrt[4]{2x} + 6 \sqrt[4]{2x}$
In this case, you would simplify it by adding them together.
$4 \sqrt[4]{2x} + 6 \sqrt[4]{2x}$ = $10 \sqrt[4]{2x}$
And can even be changed to an exponential equation:
$10(2x)^{ \frac{1}{4} }$

Step-by-step explanation:

Flat rate is the y- intercept b = 11.2

Charge per mile is the slope m = 3.1

The equation is:

y = 3.1x + 11.2

Dovator [93]

Answer:

The function is $d=10t$

domain is 0 to 0.2 hour.

range is 0 to 2 miles.

Step-by-step explanation:

Given that,

Average velocity = 10 miles/hour

Time = 12 min = 0.2 hour

We need to write a function that models the student's distance from home

Using formula of distance

$d=v\times t$

Where, v = velocity

t = time

d = distance

Put the value into the formula

$d=10t$

This is a function.

We know that,

Domain :

Domain shows the time.

So, domain = 0 to 0.2 hour

Range :

Range shows the distance.

The range at t =0,

Put the value of t in the function

$d = 10\times0=0$

The range at t =0.2 hour

$d = 10\times0=0$

$d=2\ miles$

So. range = 0 to 2 miles

Hence, The function is $d=10t$

domain is 0 to 0.2 hour

range is 0 to 2 miles
