Solve 2+4+6 +⋯ +48−3−5−7 − … −51

WITH EXPLANATION PLEASE!!!

-98

Step-by-step explanation:

Given:

2+4+6 +⋯ +48−3−5−7 − … −51

Find solution:

(2+4+6 +⋯ +48)−(3+5+7+ …+51)

Computation:

an = a + (n-1)d

For

(2+4+6 +⋯ +48)

48 = 2 + (n-1)2

n=22

For

(3+5+7+ …+51)

51 = 3 + (N-1)2

N = 24

Sn = n/2(a+an)

So

22/2(2+48)-24/2(3+51)

550 - 648

-98

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.
