Answer:

The arc length of the semicircle is 5 \pi\ units or 15.7\ units

Step-by-step explanation:

The complete question in the attached figure

we know that

The circumference of a semicircle is given by the formula

C=\frac{1}{2}\pi D

where

D is the diameter of the semicircle

we have

D=10\ units

substitute

C=\frac{1}{2}\pi (10)

C=5 \pi\ units ----> exact value

Assume

\pi =3.14

C=5(3.14)=15.7\ units ----> approximate value

therefore

The arc length of the semicircle is 5 \pi\ units or 15.7\ units

Tasya [4]

Answer:

Rate = 6.56%

Step-by-step explanation:

Principal (P) = $5000

Interest (I) = $6312

Time (T) = 4 years

Rate (r) = ?

This question is involves simple interest and with the formula, we can easily plug in the values to find the rate.

S.I = P(1 + rt)

S.I = simple interest

P = principal

R = Rate

T = Time

6312 = 5000(1 + r*4)

6312 = 5000 + 5000*4r

6312 - 5000 = 20000r

1312 = 20000r

r = 1312 / 20000

r = 0.0656

Rate are calculated in percentage hence we'll multiply it by 100

R = 6.56%

What’s the x intersect of the equation<br> -25 - 12x = -(-8x - 6) -3(5x+12)
erik [133]

-25 - 12x = -(-8x - 6) - 3(5x + 12)

Distributive property.

-25 - 12x = 8x + 6 - 15x - 36

Combine like terms.

-25 - 12x = -7x - 30

Add 12x to both sides.

-25 = 5x - 30

Add 30 to both sides.

5 = 5x

Divide both sides by 5.

x = 1

The x-intersect is 1.
