Answer:
Step-by-step explanation:
This is a hard one
We have to use the rational root theorem
= 0
We have to find all the factors of a and d and put them in a fraction
We then plug them into the equation to see if any of them work
The equation isn't true when plugging 1, but is true when plugging in 1/2
factored form of 1/2 is (2x-1)
Then we divide the original equation by (2x-1) (you can use synthetic division or long division, it would be hard to type out the process for that) to get
So now the equation is
Solve the second half of this equation using the quadratic formula to get
and
We already know the solution for the first half of the equation (1/2)
So the final answers are:
Answer:
15.95 feets
Step-by-step explanation:
Given that:
Angle of elevation = 62°
Using trigonometric relation :
Tanθ = opposite / Adjacent
From the drawing attached :
Opposite = 30 feets
Distance between girl and lighthouse = d
Tan 62 = 30 / d
1.8807264 * d = 30
d = 30 / 1.8807264
d = 15.951283
d = 15.95 feets
Answer:
C
Step-by-step explanation:
I'm guessing the answer would be 141 pennies in a rectangular array I think I'm right but i might be wrong
12,571.4286 you subtract 1000 from the total, and divide by 7.
