Answer:10
Step-by-step explanation:
<span>x = {-4, 4}
</span>
<span>Divide each side by '5'.
x2 = 16
Simplifying
x2 = 16
Take the square root of each side:
x = {-4, 4}</span>
Answer:45
Step-by-step explanation:
y varies directly as x^2
y=k x x^2
When y=5 x=3
5=k x 3^2
5=k x 9
K=5/9
Relationship is y=5x^2/9
y=(5x9^2) ➗ 9
y=(5x81) ➗ 9
y=405 ➗ 9
y=45
=sin30cos60 + sin60cos30
=(1/2)(1/2) + (√3/2)(√3/2)
=1/4 + 3/4
=1+3/4
=4/4
=1
A) 17.69
You just substitute the h for 3
