3. Which inequalities show a correct relationship between expressions?
igomit [66]

Answer: a and d

Step-by-step explanation:

First of all, we need to make a analysis of each letters:

a. factoring 32 = 2.2.2.2.2 = 2^{5}

2^{5}^{3} = 2^{15}

then,

16 = 2^{4}

but 2^{4}^{4} =2^{16}

in conclusion that, this inequality is correct

b. 27 =  3^{3}

this first situation is equal to  3^{9}

the second situation is:

81 =  3^{4}

and  3^{4}^{4} = 3^{16}

it's a mistake.

c. factoring 9: 9 = 3^{3}

3^{9} <  3^{5}

it's wrong.

d. factoring 8 = 2^{3}

factoring 32 =  2^{5}

2^{12} >  2^{10}

This is true.

Finally.. our correct answers is a and d.

Which graph shows the correct solution to the inequality below?
Assoli18 [71]

Answer:

Third Option

Step-by-step explanation:

3x + 18 > 6x - 9

We have to find the value of x for this

Subtract 18 from both sides to leave 3x alone

3x > 6x - 27

Subtract 6x from both sides to be able to find the value of x

-3x > -27

Divide by -3 on both sides

x > 9

The answer would be the third option, since X is anything greater than 9

If an object is projected upward from the top of a 144 ft building at 112 ft per sec, its position (in feet above the ground) is
Mandarinka [93]

When it hits the ground the height would be 0.

Set h to 0 and solve for t ( time)

0 = -16t^2 + 112t + 144 divide both sides by -16:

T^2 -7t -9

Factor the polynomial :

( t- 8.1) (t+1.1

Solve for t setting each equation to 0:

T = 8.1 or t = -1.1

Time has to be positive, so the answer is

8.1 seconds

Depending on how everything gets rounded it could also be 8 seconds.
