Answer:
k = 11
Step-by-step explanation:
What the factor theorem is telling us is that if x + 1 is a factor of 2x - kx²-8x + 5 then when x = - 1 is put into the equation, the result will be 0. That's because x +1 = 0 when x = - 1
f(-1) = 2(-1) - k(-1)^2 - 8(-1) + 5
f(-1) = -2 - k(1) + 8 + 5 = 0
-k*(1) + 11 = 0
-k = -11
k = 11
Answer:
Welll....from the diagram, you can see you have two triangles (one on each side)
area of triangle = 1/2 base*height = 1/2 * 2 x 10 = 10 ft2 each
then you are left with a rectangle 13 ft x 10 ft = 130 ft^2
130 + 10 + 10 = 150 ft2
or you could just use the formula for area of parallelogram base * height = 15 * 10 = 150 square feet

Can I get a brainliest plsss
We can also think of this problem as f(x) + g(x). Therefore, all we need to do is add the two functions together.
x + 4 + 3x^2 - 8 || Write it out!
3x^2 + x + 4 - 8 || Rearrange in order of decreasing exponents. No need to combine and rearrange all at once!
3x^2 + x - 4 || Combine like terms!
Hope this helps!! :)
Answer:
Quadrant lll
Step-by-step explanation:
Since the cosine of the angle is positive, the sine of the angle must be negative and the terminal side of the angle lies in either Quadrant III or IV.
