Answer:

1) D. <em>343.17</em>

2) C but not sure

Step-by-step explanation:

1) area of triangle is 1/2* base* height= 1/2*18*24 = 216ft²

area of circle is πr²

area of semicircle is πr²/2

diameter=18

radius= 18/2=9

πr²/2 = (22/7* 9*9) / 2

=127.2 (approx)

total area = 127.2+ 216= 343.2

(-3 + 8i) – (-4 - 6i)

Dafna1 [17]

Answer:

1+14i

Step-by-step explanation:

- remove unnecessary parentheses (-3 + 8i) -(-4 - 6i) = -3+8i - (-4-6i)

- when there is a - in front of an expression in parentheses, change the sign of each term in the expression -3+8i+4+6i

- calculate the sum

(-3+4=1) = 1+8i+6i

- collect like terms

(8i+6i=14i) = 1+14i

SOLUTION: 1+14i

Suppose g(m) varies inversely with M and g (m) = 3.5 when m = 10.

mojhsa [17]

Answer:

m =7.

Step-by-step explanation:

Let the constant number = k.

g(m) = k/m,

3.5 = k/10,

k = 35.

Thus, when g(m) = 5 = 35/m, m = 7.
