Answer:
100 miles
Step-by-step explanation:
Create equations.
Company A: y = 0.28x + 50
Company B: y = 0.78x
These are equal to each other.
0.78x = 0.28x + 50
0.5x = 50
x = 100
<span>the longitude of the ramp is determined by the Hypotenuse, we have the angle(4.5Âş), and the opposite side (3ft), so with the Sin(x) trigonometric function ( sin(x)=opposite/hypotenuse ) we can calculate the answer.
Using the formula, hypotenuse=opposite/sin(x)
Hypotenuse=3ft/sin(4.5)
hypotenuse=3ft/0.0784591
hypotenuse=38.236482
the ramp must be 38.2 ft long.
the calc must be in degrees to get an accurate answer to any trigonometric function</span>
Answer:
Okay so for finding the equation of a line, which is a function, the equation is set to y, so you can eliminate A and B. When the slope of an equation is 0, we are saying that the y value of any point of the line is going to be the same, which is 9 from the given point (2,9).
So the answer is C. y=9
Step-by-step explanation:
Answer:
f(x)=-3(x-8)(x+2)
Step-by-step explanation:
f(8)=-3(8-8)(8+2)=-3×0×10=0
f(-2)=-3(-2-8)(-2+2)=-3×(-10)×0=0
f(0)=-3×(0+8)×(0+2)=-3×8×2=-48
108÷6 = 18 and 84÷6=14 last one is 184÷8=23
