Slope of perpendicular is -1/3.
Then equation is
y-5=(-1/3)(x+9)
I believe it's 8 because it's scale is 4 times bigger.
2×4=8
Answer:
I got u
Step-by-step explanation:
Write out the expression 2 - (2x-7)^2. That's it.
But if you want to go further and remove the parentheses, first expand (2x-7)^2: (2x-7)^2 = 4x^2 - 28x + 49,
and then subtract this result from 2:
2 - (4x^2 - 28x + 49) (It's important to use parentheses here)
Now, following the distributive property of multiplication, remove the parentheses:
2 - 4x^2 + 28x - 49
Combining the constants, we get the final answer: - 4x^2 + 28x - 47
Exponential function model:
After 5 years: t = 5
f ( 5 ) = 175 * 1.22^5 = 175 * 2.70271 = 473
Answer :
Approximate population after 5 years will be 473.
