Suppose ∠A and ∠B are complementary angles, m∠A = (3x + 5)°, and

mario62 [17]

m∠A + m∠B = 90
(3x + 5) + (2x - 15) = 90
(3x + 2x) + (5 - 15) = 90
5x - 10 = 90
+ 10 + 10
5x = 100
5 5
x = 20

m∠A = 3x + 5
m∠A = 3(20) + 5
m∠A = 60 + 5
m∠A = 65

m∠B = 2x - 15
m∠B = 2(20) - 15
m∠B = 40 - 15
m∠B = 25

A standard deck of 52 cards contains 4 aces. What is the probability of randomly drawing a card that is not an ace?

Stells [14]

I There would be 52-4 = 48 cards that are not aces.

The probability of picking a non ace card would be 48 out of 52, which is written as 48/52, which reduces to 12/13

Find f(3). f(x) = x2 + 5x - 9 A) 7 B) 10 C) 9 D) 15

Lelechka [254]

Answer:

f(3) = 15. Correct: D)

Explanation:

Numeric Value of a Function

The value of a function f(x) when x = a is calculated by replacing the x for a. We have the function:

$f(x)=x^2+5x-9$

It is required to find f(3), or the numeric value of f when x=3. Replace x for 3

$f(3)=3^2+5(3)-9$

$f(3)=9+15-9$

$f(3)=15$

A) Incorrect. f(3) is not 7

B) Incorrect. f(3) is not 10

C) Incorrect. f(3) is not 9

D) Correct. f(3) =15 as found above.
