A spheres radius is multiplied by 2. How is it’s surface area affected

Mathematics
1 answer:
dexar [7]4 years ago

Answer:

The surface area is multiplied by 3.

Step-by-step explanation:

If r is the radius of a sphere its surface area = 4(pi)r^2. If the radius is doubled then its surface area = 4(pi)(2r)^2 = 4*4(pi)r^2. So the surface area becomes 4-fold or the increase in surface area is 300%.

C and D

Step-by-step explanation:

i=√-1

n/4=x.5

since 2 is the remainder

n=2x

then i^n=i^2x

when x is even, i^n =1

when x is odd, i^n=-1

Determine if (x+1) is a factor 4x^2 + 2x - 5Use synthetic division
ikadub [295]

Given

4x^2+2x-5

Divide it by (x+1) using synthetic division, as shown below

The green line is a minus sign.

Thus,

\Rightarrow4x^2+2x-5=(x+1)(4x-2)-3

Therefore, since the remainder is different than zero, (x+1) is not a factor of 4x^2+2x-5

How to solve 3x^2+22x=-35 by factoring
Zepler [3.9K]

Answer:

x = -7/3 or -5

Step-by-step explanation:

3x^2 + 22x = -35

3x^2 + 22x + 35 = 0

(3x + 7) (x + 5) = 0

so for 3x+7:

3x+7 = 0

3x = -7

x = -7/3

So for x + 5:

x + 5 = 0

x = -5
