Answer:

16

Step-by-step explanation:

We have the expression:

b^2

We know that b= -4. Therefore, we can substitute -4 in for b.

(-4)^2

-4^2 is the same as multiplying 4, 2 times.

-4^2

=-4*-4

2 negative numbers multiplied together make a positive number.

Keeping the properties of exponents in mind, to what power must you raise the expression 7 1/2 to get 7 as a result
zhenek [66]
For this case we have the following expression:
 7 ^ {(1/2)}

 Rewriting the expression we have:
 (7 ^ {(1/2)}) ^ x

 Where,
 x: exponent to which we must raise the expression to obtain 7 as a result.
 We have then:
 7 ^ {((1/2) x)}

 The exponent must be equal to 1:
 (1/2) x = 1

 Clearing x we have: 
 x = 2

 Substituting valres:
 7 ^ {((1/2) 2)}

7 ^ 1

7

3) A construction company uses 900 bricks to
denis-greek [22]

Answer:$570

Step-by-step explanation:If it is 900 for 2 walls, and they need 6 walls, then multiply 900 by 3. They would use 2700 bricks for 6 walls. Multiply 2700 by 0.10 to get the price for all the bricks, 270 dollars. If labor to build each wall costs 50 dollars then multiply that by 6 and add it to the 270 dollars. It costs 570 dollars to build 6 walls

A cylinder with 3 radius and and height is 2 inches what is the volume?
VashaNatasha [74]

Answer:

\huge\boxed{\sf V = 56.5 \ in.^3}

Step-by-step explanation:

Radius = r = 3 in.

Height = h = 2 in.

<u>Volume:</u>

\sf Volume \ of \ the \ cylinder = \pi r^2 h\\\\V = (3.14)(3)^2(2)\\\\V =(3.14)(9)(2)\\\\V = (3.14)(18)\\\\V = 56.5 \ in.^3\\\\\rule[225]{225}{2}
