The sequence 28, 34, 40, 46, 52, ..., 88 has 11 terms. Find the sum of the 11 terms.
a) 550
c) 610
Ob) 638
od) 288

D) 638

Step-by-step explanation:

The pattern shows that they all increase by 6 each time.

The 11 numbers in the pattern would be 28, 34, 40, 46, 52, 58, 64, 70, 76, 82, 88.

Adding all of them together, 28 + 34 + 40 + 46... and so on up to 88. This would equal 638.

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.

u also answered this so i think u would know but i am here to

put in or use mine

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1
