F(x) = 2x² - 2x + 7
g(x) = x² + 9x - 6
f(x) - g(x) = 2x² - 2x + 7 - (x² + 9x - 6)
= 2x² - 2x + 7 - x² - 9x + 6
= 2x² - x² - 2x - 9x + 7 + 6
= x² - 11x + 13
The 1st option.
Answer:
x= 616326743 / 31419696919
Step-by-step explanation:
62839393838x = 1232653486
Let's solve your equation step-by-step.
62839393838x=1232653486
Step 1: Divide both sides by 62839393838.
62839393838x / 62839393838 = 1232653486 / 62839393838
x= 616326743 / 31419696919
Answer:
84 cm^2
Step-by-step explanation:
The area of a triangle is
A = 1/2 bh where b is the length of the base and h is the height
A = 1/2 ( 5+9) * 12
A = 1/2 (14) * 12
A =84
Answer:
0
Step-by-step explanation:
To find the slope, we use the formula
m= (y2-y1)/(x2-x1)
= (6-6)/(-2-4)
= 0/-6
=0
We are told that a population of insects grows exponentially and we are given a table of data about insect population growth. We are asked to find population of insects at the end of week 11.
The initial insect population is 20 and at the end of 1st week population increases to 30.
Let us find growth percentage of insect population,




We can see that insect population is growing at rate of 50% per week.
Now let us write an exponential function for our population.
, where P(w) represents population at the end of w weeks.
Let us substitute w=11 in our function to find insect population at the end of 11 weeks.




Therefore, population of insects at the end of 11th week will be 1730.
