Answer:
R = 30
Step-by-step explanation:
Given y is directly proportional to R² then the equation relating them is
y = kR² ← k is the constant of proportion
To find k use the condition when R = 4, y = 24, then
24 = k × 4² = 16k ( divide both sides by 16 )
1.5 = k
y = 1.5R² ← equation of proportion
When y = 1350 , then
1350 = 1.5R² ( divide both sides by 1.5 )
900 = R² ( take the square root of both sides )
= R , that is
R = 30
<span>a right triangle the measure, so right angle = 90
let x = other acute angle
</span><span>one acute angle is 8 times the measure of another angle = 8x
</span>
x+8x+90=180
9x=90
x = 10
answer:
<span>measure in degrees of the smallest angle in the triangle = 10</span>
The questions asks for the domain of [f/g](x).
That is f(x) / g(x) = [x^2 - 25] / [X-5].
The domain of that functions are all the real except those where the denominator becomes zero.
You find those points by doing X - 5 = 0 => x = 5.
Then, the domain of [f/g](x) is all real numbers except x = 5.
You take 3•4 to get 12, then you add a zero to that and get 120. You then multiply by six and get 720.
