Answer:
√3
Step-by-step explanation:
The formula for the area of a trapezoid is
Plugging in our information, we have
Combining like terms in parentheses, we have
To cancel the 1/2, we will multiply both sides by 2:
Divide both sides by 8:
Divide both sides by √2:
3(4x - 2) = 2(6x - 3)
First, expand. / Your problem should look like: 12x - 6 = 12x - 6
Second, since both sides are equal, there and infinite solutions.
Answer: B) infinite solutions.
The area of the parallelogram spanned by the given vectors is equal to the magnitude of their cross product.
(i + j + k) × (-2i + 3j + k)
= -2 (i × i) - 2 (j × i) - 2 (k × i)
… + 3 (i × j) + 3 (j × j) + 3 (k × j)
… + (i × k) + (j × k) + (k × k)
= - 2 (j × i) - 2 (k × i) + 3 (i × j) + 3 (k × j) + (i × k) + (j × k)
= 2 (i × j) - 2 (k × i) + 3 (i × j) - 3 (j × k) - (k × i) + (j × k)
= 5 (i × j) - 3 (k × i) - 2 (j × k)
= 5 k - 3 j - 2 i
Then the area of the parallelogram is
||-2 i - 3 j + 5 k|| = √((-2)² + (-3)² + 5²) = √38
Is it -23x × 3y =5 ?
If it is then
y = 5 / -23x × 3
Final answer :
y = 5 / -69x
You can put the negative sign in the middle
Kinda like this
5
- --------
69x
Ok so
we don't know the sign so it could be
4x^2-8x+60 or
4x^2-8x-60
( if it is the first one, go to AAAAAAA
if it is second one go to BBBBBBBBBBB)
to find the zero fo the function, set the fnction to zero
then factor since if you had xy=0, then assume that x and y=0
AAAAAAAAAA
4x^2-8x+60=0
4(x^2-2x+15)=0
4 you get a nonreal root so the missing sign is probably a negative sign
if you were to graph this one, there is no x intercept
BBBBBBBBB
4x^2-8x-60=0
4(x^2-2x-15)=0
4(x-5)(x-3)=0
x-5=0
x=5
x-3=0
x=3
3<5
smallest zero is 3
I would say the smallest zero is 3
