Answer:
A. 9
Step-by-step explanation:
F(-2) = 9
We are given the polynomial function;
F(x) = -2x3 + x2 + 4x-3
In order to determine F(-2) using the remainder theorem, we plug in -2 in place of x in the equation and simplify;
F(-2) = -2(-2)^3 + (-2)^2 + 4(-2) - 3
F(-2) = 9
Answer:
A
Step-by-step explanation:
Evaluating F(- 2) gives the remainder on dividing the polynomial by (x + 2)
F(- 2) = - 2(- 2)³ + (- 2)² + 4(- 2) - 3 = 16 + 4 - 8 - 3 = 9 ← remainder

calculate the mean number of videos watched last week by the 20 girls.
show working out please
Answer:
Step-by-step explanation:
Set this up as a proportion with oz on the top and grams on the bottom and then fill in with what you are given:
Cross multiply to get x = 28*3 so x = 84 g
Do the same for the next ratio:
and cross multiply again to get
28x = 140 so
x = 5 oz
Answer:
Ounces Grams
1 28
3 84
5 140
Step-by-step explanation:
Since one ounce is 28 grams you would do 3 times 28 which gives you 84 and so 3 ounces if equal to 84 grams. Now we have to find how many ounces in 140 grams. We would do 140 divided by 28 which gives us 5 and so 140 grams is equal to 5 ounces. Hope this helps! If not well...
Answer:
16
Step-by-step explanation:
72 / 4 1/2 = 16. You need to divide to find out the answer.
In summary, a line is perpendicular to x + 3y = -3 if its slope is 3.
The subject requested is about finding the slope of a line that is perpendicular to the line specified by the equation x + 3y = -3. To find the slope, we'll first have to rewrite the given equation in slope-intercept form, y = mx + b, where m is the slope and b is the y-intercept.
Rewriting x + 3y = -3, we get y = -x/3 - 1. So the slope of the given line is -1/3. Now, two lines are perpendicular if and only if the product of their slopes is -1. Therefore, the slope of the line perpendicular to the given line will be -1 / original slope = -1 / (-1/3) = 3.
Thus, the slope of a line perpendicular to the line x + 3y = -3 is 3.
