The answer is b. Notice that the problem is looking for the reaction to product ratio, which is tricky because it's easy to follow the order of the column and calculate the inverse of it. Check the first ratio, 0.3/2=0.15, we can immediately choose b out of the other 4 choices.
If we take the angle 60° as the angle from the ground to the beam and let x be the distance from the base of the billboard to the bottom of the brace, the trigonometric equation which would best represent the scenario is,
x = (20 ft) (cos 60°)
x = 10 ft
Thus, the distance from the base of the billboard to the bottom end of the brace is 10 ft.
Answer:
It is not a triangle
Step-by-step explanation:
The Triangle Inequality theorem states that in a triangle, , where and are shorter side lengths and is the longest side length.
Given that , the given side lengths do not compose a valid triangle.
Answer:
Step-by-step explanation:
So first we need to find the area of the trash can so here is the math:
The formula:
A=LxW
Replace the letters with numbers:
8=2x4
So the area is 8 feet now we can create an equation to solve how much money it would take to make the trash can:
8x0.79=$6.32
It would take $6.32 to make the trash can
Answer: -31
<u>Step-by-step explanation:</u>
f(x) = -x⁴ + 3x³ + x² - 8x - 16
f(3) = -(3)⁴ + 3(3)³ + (3)² - 8(3) - 16
= -81 + 81 + 9 - 24 - 16
= -31
