Answer:
Option B). x = -9, -2 and 8.
Step-by-step explanation:
The given function is f(x) = x³ + 3x² -70x - 144 and f(-9) = 0, f(-2) = 0, f(8) = 0
We have to find the solutions to the equation x³+ 3x² = 70x + 144
Now we rewrite the function in the equation form as
x³ + 3x² - 70x - 144 = 0
x³ + 3x² = 70x + 144
we know for the values of x = -9, -2, and 8 value of the function is 0. So when we rewrite the function in the form of an equation, -9, -2 and 8 will be the zero factors of the equation.
So solutions of the equation are x = -9, -2 and x = 8.
Answer:
1. Dots
2.Blank
3. Stripes
4. Stars
Step-by-step explanation:
Well the total is 30 and we just have to see the fraction of each time in landed on a specific part of the spinner. So first the probability of landing on dots is 6/30 = 1/5
Then the experimental probability of getting a blank is 8/30 = 4/15
Continuing in the same manner getting stripes would have a chance of 12/30 which is 2/5
Finally I'm gonna let you think about how I got the last one and why I did what I did :)
Can you post the image because I need to clarify in your trigonometry hw
Step-by-step explanation:
because x = 75 is the corresponding angel
and x value was 75 then (3z-9) was straight angel they are sum was 180 degree. my answer was wrong please report
