Answer: The correct answer is B) 19.5(sin35)
Step-by-step explanation:
I took the practice
A) 2^(x+3)= 4^(2x)
make base number the same
2^(x+3)= 2^2 (2x)
set the exponents equal to eachother
x+3=2 (2x)
x+3=4x
-x both sides
3=3x
÷3 both sides
x=1
b) 16^(1/5)×2^(x)=8^(3/4)
make base same number
2^4 (1/5)×2^(x)=2^3 (3/4)
2^(4/5)×2^(x)=2^(9/4)
set exponents
4/5 +x=9/4
-4/5 both sides
x= 29/20
the domain is all numbers except x = -4 because when -4 is plugged in for x the equation divides by 0 which is impossible
Answer: 50,40
Step-by-step explanation:
because a right angle is 90 degress
