The sum of the 5 terms in the arithmetic series is 40.
Step-by-step explanation:
Step 1; First we need to determine the three values between a1= -14 and a5=30. The difference between the first and fifth value = 30 - (-14) = 30 + 14 = 44.
Since there are 4 values after a1 we divide the difference by the number of terms, the difference between each term = 44 / 4 = 11. So the difference between each term is 11.
Step 2; To find out the terms we just add the difference to the previous number.
a1 = -14.
a2 = -14 + 11 = -3.
a3 = -3 + 11 = 8.
a4 = 8 + 11 = 19.
a5 = 19 + 11 = 30.
So a1 + a2 + a3 + a4 + a5 = -14 -3 + 8 + 19 + 30 = 40.
Answer:
A. the times at which the golf ball is on the ground
Step-by-step explanation:
The expression of the function is
h(x)= -4x^2+36x
The roots can be seen in the image below
You have a formula which represents the height over time.
The roots of the equation indicate that the height is equal to zero
The correct option is
A. the times at which the golf ball is on the ground
The ball is in the ground at x= 0 and x = 9 seconds
Answer:
4x (6) 13 4 by 2•58+7(8) 13+4
Problems 5, 7A, and 7C are the only ones with correct answers.
But for 1 - 6, you're also supposed to color in the same amount of the big square,
and for 7, you're also supposed to mark a dot on the number line. You haven't
done any of these things.
All of these problems are just changing a fraction to another fraction that's
equivalent but has a different denominator. Whatever the old denominator
was multiplied by to get the new one, the old numerator also has to be
multiplied by the same thing. If you don't do that, then you've changed
the value of the fraction.
You have some more work to do.
Answer:
0.04
Step-by-step explanation:
5^4=625
5^-3= 0.008
0.008^2=0.000064
0.000064*625=0.04
