We use this formula:
<span>Area = ½ • side 1 • sine (A) • side 2
</span>Area = <span>½ • 6 • sine (74) • 7
</span><span>Area = <span>21 • sine (74)
Area = 21*0.96126
Area = </span></span><span><span><span>20.18646
</span>
</span>
</span>
Area = 20.2 (rounded)

Angle 1 is a right angle =90 °
so 5x-85=90
5x=90+85
5x=175
x=35
Answer:
<u>
</u>
Step-by-step explanation:
For the standard form equation to model the values in the table, each value of x in the table should give the matching the y value when substituted into the equation. We will test each equation:

Answer:
Correct answer is f(x) = (625^x)^1/4
Step-by-step explanation:
We know that
625 = 5^4
This means
f(x) = (625^x)^1/4
f(x) = (5^(4x))^1/4
But we know this is equivalent to
f(x) = (5^(4x*(1/4))) =
= 5^(x)
Correct answer is f(x) = (625^x)^1/4
