If q(x)=7x^2-1 ; find Q(-10)

Mathematics

maksim [4K]3 years ago

In terms of PEMDAS, you would first find -10 squared, which is 100, and multiply it by 7, giving you 700-1. The answer would be 699.

If you weren't going by PEMDAS, then you would take 7, multiply it by -10, square that, and subtract one from it. -70^2=4,900. Subtract 1, and your answer is 4,899.

Find the sum of a finite arithmetic sequence from n = 1 to n = 10, using the expression 3n − 8.
maw [93]

Answer:

The answer is 85

Step-by-step explanation:

The equation used to find the sum of an arithmetic series is: (n/2) * (a1 + an).

n in this case is 10 (the number of numbers in the series)

an is 22 (plug in 10 to the expression 3n-8)

and a1 is -5 (plug in 1 to the expression 3n-8)

so when you plug everything in to the final equation, you get

(10/2) * (-5 + 22)

5 * 17

PLEASE ANSWER, WILL MARK CORECT ANSWER BRAINLIEST
Anna007 [38]

Answer:

B, D

Step-by-step explanation:

-3(0.15 - 0.2 +0.25p) = -3(-0.05 +0.25p) = 0.15-0.75p

A doesn't work because -3(0.15 - 0.2 +0.25p) = -0.45+0.6-0.75

C doesn't work because 3(0.15+0.2+0.25p) = 0.45+0.6+0.75 which doesn't equal -0.45+0.6-0.75.

E doesn't work because 0.15-0.2 = -0.05 not 0.05.
