Answer:

d =±2sqrt(7) i

Step-by-step explanation:

d^2 = -28

Take the square root of each side

sqrt(d^2) = ±sqrt(-28)

d = ±sqrt(-28)

d = ±sqrt(-1)sqrt(28)

We know that sqrt(-1) = i

d =±i*sqrt(4)sqrt(7)

d =±i 2sqrt(7)

d =±2sqrt(7) i

A) A rectangular prism 10 m 10 m 50 m Volume: Surface Area:

Rama09 [41]

Answer:

$\huge\boxed{V=5,000m^3}\\\boxed{SA=2,200m^2}$

Step-by-step explanation:

The formula of a volume of a rectangular prism $a\times b\times c$ :

$V=abc$

The formula of a surface area of a rectangular prism $a\times b\times c$ :

$SA=2(ab+ac+bc)$

We have

$a=10m;\ b=10m;\ c=50m$

Subtitute:

$V=(10)(10)(50)=5,000(m^3)\\\\SA=2\bigg((10)(10)+(10)(50)+(10)(50)\bigg)\\=2(100+500+500)=2(1100)=2,200(m^2)$

PLEAS HALP MEH< What angle measure is complementary to a 37° angle

Fynjy0 [20]

The angle measure would be 53°.

Complementary angles add up to 90° so, if you're trying to find the other angle measure just subtract the angle measurement that you already know from 90.

90 - 37 = 53

Hope this helps! :)
