Step-by-step explanation:

(5 - 2i) + (-4 + 81)

5 - 2i + 77

= 82 - 2i

Answer 2

1 + 6i

we open the brackets to give us

5 - 2i - 4 + 8i

collecting like terms, we have,

-2i + 8i + 5 - 4

6i + 1

or

B, 3 8/9

Step-by-step explanation:

It all comes down to equivalent fractions.

2 1/3 as an improper fraction is 7/3.

1 5/9 as an improper fraction is 14/9. 1/3 = 3/9.

With that being said 7 x 3 = 21 resulting in 21/9.

14/9 + 21/9 = 35/9.

35/9 as a mixed fraction is 3 8/9.

Makers of a new pain-relieving medication claim that it relieves chronic pain faster than the current top-selling pain reliever on the market. A
double-blind experiment was conducted in which 10 people who experience chronic pain were randomly selected to take either the new or the
current medication. Each of the 10 people recorded the time, in minutes, from taking the medication until pain relief. After an appropriate time
period, each of the 10 people took the other medication and recorded the time from taking the medication until pain relief. The medication each
person took first was randomly determined, and because both medications look the same, the people in the study did not know which medication
was taken first. The table below shows summary statistics for the results.​

Find the area of a sector, whose perimeter is 40 cm, and the radius is 8 cm.

Answers

Answer:

96 cm²

Step-by-step explanation:

From the question,

s = (2πr∅/360)+2r................. Equation 1

Where s = Perimeter of a sector, r = radius, ∅ = angle subtend by the sector at the center of the circle.

Given: s = 40 cm, r = 8 cm

Constant : π = 3.14.

Substitute into equation 1 and solve for ∅

40 = (2×8×3.14×∅/360)+(2×8)

40 = (50.24∅/360)+16

40-16 = 50.24∅/360

50.24∅/360 = 24

50.24∅ = 24×360

50.24∅ = 8640

∅ = 8640/50.24

∅ = 171.97°

Area of a sector (A') = ∅πr²/360

A' = 171.97×3.14×8²/360

A' = 95.997

A' ≈ 96 cm²
