Answer:

  (b)  -15

Step-by-step explanation:

The area under the curve from -5 to +5 can be divided into two trapezoids. The one from x=-5 to x=1 has an area of ...

  A = 1/2(b1 +b2)h = 1/2(1 +6)(5) = 17.5

The one from x=1 to x=5 has an area of ...

  A = 1/2(4 +3)(-1) = -3.5

So, the total area from x=-5 to x=+5 is 17.5 -3.5 = 14. This is the amount by which f(x) increases from f(-5) to f(5). That is ...

  f(-5) +14 = -1

  f(-5) = -15

Find the missing term in the geometric sequence : 8 , 20 , 50, 125 , ____

Answers

Answer:

312.50

Step-by-step explanation:

8 , 20 , 50, 125 , 312.50

First term, a = 8

Second term, ar = 20

Find common ratio, r

Substitute a = 8 into second equation

ar = 20

8r = 20

r = 20/8

r = 2.5

Find the fifth term

ar⁴

= 8 * 2.5⁴

= 8 * 39.0625

= 312.50

Fifth term, ar⁴ = 312.50

Answer: The answer is 75 and since you have to round it up to the nearest tenth the answer would be 80.

Step-by-step explanation:

You first have to add all the score numbers: 60, 65, 70, 75, 80, 85, 90

Then, you will get 525

Now, divide that by how many scores there are which is 7 and you get 75

Finally, 75 rounded to the nearest tenth is 80!
