Answer:

D

Step-by-step explanation:

This is an arithmetic sequence since there is a common difference between each term. In this case, adding

5

to the previous term in the sequence gives the next term. In other words,

a

.

This is the formula of an arithmetic sequence.

a n = a 1 + d ( n − 1 ) Substitute in the values of a 1 = 4 and d = 5 . a n = 4 + ( 5 ) ( n − 1 ) Simplify each term. Tap for more steps... a n = 4 + 5 n − 5 Subtract 5 from 4 . a n = 5 n − 1

Lena [83]

Answer: A. 87 feet


Step-by-step explanation:

1. You can find the t value of the vertex of the parabola as following:

t=-\frac{b}{2a}

2. Substitute values:

a=-16

b=70

Then:

 t=-\frac{70}{2(-16}

t=2.18

3. Substitute the vaue obtained into the equation given in the problem. Therefore, you obtain the following result:

h=-16t^{2}+70t+10\\h=-16(2.18)^{2}+70(2.18)+10\\h=86.56

4. To the nearest foot:

h=87 feet

Can someone please help me?
Aneli [31]

Answer:

A

Step-by-step explanation:

to find the inverse, there are two steps

1-interchange x and y

2-solve for y

so y=x+1/x

interchange to get x=y+1/y

and solving for y we multiply both sides by y to get xy=y+1

subtract both sides by y yielding xy-y=1

factor out y to get y(x-1)=1

then divide to get y=1/x-1
