Answer:
Amplitude is 3
Step-by-step explanation:
in y=-3sin5x
the number in front of sign is always the amplitude. Its not negative 3 because the negative simply means it reflects across the x-axis
The answer is. A) y=-4/5x-7
Just compare, and they will equal each other.
Answer:
$3644675.9
Step-by-step explanation:
The initial investment is $100000. The interest rate is 12%.
We are asked to determine the final amount the investment will become after 30 years if the interest is compounded weekly.
The weekly interest rate is 
%.
Assuming 1 year equivalent to 52 weeks.
Hence, using the formula of compound interest the final sum will be
= $3644675.9 (Approximate)
Short Answer B
Argument
A
A will give you x = +/- 5i
x^2 + 25 = 0
x^2 = - 25 Take the square root.
sqrt(x^2) = +/- sqrt(-25)
x = +/- (5)i which is a complex number.
B
Is the answer
x^2 = 25
sqrt(x)^2 = sqrt(25)
x = +/- 5
C
Can't be factored just by looking at it. You can show that C is not true just by putting 5 into the equation
f(x) = x^2 + 10x - 25
f(5) = 25 + 10*5 - 25
f(5) = 50
C is not true.
D
D can be eliminated as C was
f(x) = x^2 - 5x - 25
f(5) = -25 ( l'll let you show this is not true). 5 is not a solution because it does not make f(x) = 0
