Answer:
r=-7/17
Step-by-step explanation:
6r-7=23r=
We move all terms to the left:
6r-7-(23r)=0
We add all the numbers together, and all the variables
-17r-7=0
We move all terms containing r to the left, all other terms to the right
-17r=7
r=7/-17
r=-7/17
Answer:
YEs
Step-by-step explanation:
He is correct. as long as his coin has 2 sides
Given that the angles of the two sectors are equal, we can find the relationship between the angles, radii, and the lengths of the arc
The length of the arc (S) is given by the formula
Then we can make the angle the subject of the formula
For the first sector
For the second sector
Simplifying the equation, we will obtain
I think it’s B sorry if I’m wrong
Answer:
No
Step-by-step explanation:
If (x - h) is a factor of f(x) then f(h) = 0
Here
f(x) = 2 - 3x³ + 4x² + x + 2 and
if divisor (x - 2) is a factor the f(2) = 0
f(2) = 2 - 3(2)³ + 4(2)² + 2 + 2
= 2(16) - 3(8) + 4(4) + 4
= 32 - 24 + 16 + 4
= 28 ≠ 0
Then (x - 2) is not a factor of the polynomial
