sladkih [1.3K]3 years ago
5 0

Answer:

17

Step-by-step explanation:

Substitute the value of the variable and simplify.

(-(2))^{(2+2)} +2^{(2-2)}

-2x^{2+2} =2^{4} = 16

2^{2-2} =2^{0}

Anything raised to the power of 0 is one.

16 + 1 = 17

Please help with question 22. Find a reasonable domain and range for each function. Help Help!! And please explain
steposvetlana [31]
Hey Meri!

x represents the numbers of gallons of gas in the vehicle.
The values x can represent is called our domain.

x can not take on negative values,
it wouldn't make sense to have a negative amount of gas in the car, right?

So the lower limit on our domain is zero.

The car can hold up to 17 gallons of gas,
that should make it clear what the upper limit on our domain is.

The range is the distance traveled on these gallons of gas.

If zero gallons of gas are put into the car,
then no distance will be traveled.
So the low end of our range will be zero.

If 17 gallons of gas are put into the car,
then what distance can the vehicle travel?
Use your function to determine the upper end of your range.

The graph of the function f(x) = –(x + 3)(x – 1) is shown below. Which statement about the function is true? The function is pos
Sliva [168]

Answer:

The function is negative for all real values of x where x < –3 and where x > 1

Step-by-step explanation:

we have

f(x)=-(x+3)(x-1)

using a graphing tool

see the attached figure

Verify each statement

Case 1) The function is positive for all real values of x where x < –1.

The statement is false (see the attached figure)

Case 2) The function is negative for all real values of x where x < –3 and where x > 1

The statement is true (see the attached figure)

Case 3) The function is positive for all real values of x where x > 0

The statement is false (see the attached figure)

Case 4) The function is negative for all real values of x where x < –3 or x > –1.

The statement is false (see the attached figure)

the sun shines on a flagpole, causing a shadow to be cast on the ground. the distance from the base of the pole to the tip of th
kobusy [5.1K]

Answer:

30.17feet high

Step-by-step explanation:

Given the following

the distance from the base of the pole to the tip of the shadow = 49feet (hypotenuse)

angle of elevation = 38°

Required

Height of the flagpole (opposite)

Using the SOH CAH TOA identity

Sin theta = opposite/hypotenuse

Sin 38 = H/49

H = 49sin38

H = 49(0.6157)

H = 30.17feet

Hence the flagpole is 30.17feet high
