Ax^2 + bx + c
a = 1
b = -4
c = -5
x^2 -4x-5
-5x1 = -5
-5+1 = -4
(factors of c that also add up to b)
ANSWER: (x-5) (x+1)
You have to have the same base numbers
2^4x = 2^7x
now you can cancel out the 2s and set the powers equal to each other.
4x= 7x
-11x = 0
x = 0???
im not 100% sure but i think this is what you do
6.81 times 10^16 is the answer in scientific notation
Answer:
I think the answer is b ill look into it a Lil more
In dealing with these problems, the first step to do is illustrate it. When you do, you would see a right triangle with a 55° angle between the hypotenuse and the vertical leg. Using pythagorean relations:
sin 55 = 50/x, where x is the unknown
x =50/sin55
x = 61.04 feet
