Answer:
b
Step-by-step explanation:
c11 = (-1) *3 + (-3)*2 + 2*(-4) = -3 - 6 - 8 = -17
C12 = (-1)*3 + (-3)*(-5) + 2*(-1) = -3 + 15 - 2 = 10
C13 = (-1)*5 + (-3) *2 + 2*1 = -5 - 6 +2 = -9
C21 = 2*3 + 5*2 + (-1)*(-4) = 6 +10 + 4 = 20
C22 = 2*3 + 5*(-5) + (-1)*(-1) = 6 - 25 + 1 = -18
C23 = 2*5 + 5 *2+ (-1)*1 = 10 + 10 -1 = 19
C31 = (-4)*3 + (- 5)*2 + (-4)*(-4) = -12 - 10 +16 = -6
C32 = (-4)*(3) + (- 5)*(-5) + (-4)*(-1) = -12 + 25 + 4 = 17
C33 = (-4)*5 + (- 5)*2 + (-4)*1 = -20 - 10 - 4 = -34
Answer:
-6x⁴y - 2x³y² + 9x²y³ - 3xy⁴ + y⁵
Step-by-step explanation:
(–2x³y² + 4x²y³ – 3xy⁴) – (6x⁴y – 5x²y³ – y⁵)=
–2x³y² + 4x²y³ – 3xy⁴ – 6x⁴y + 5x²y³ + y⁵=
-6x⁴y - 2x³y² + 9x²y³ - 3xy⁴ + y⁵
Answer:
Yes , it is possible (see the explanation)
Step-by-step explanation:
we know that
In a right triangle, we have two complementary angles (their sum equal to 90 degrees)
so
If two angles are complementary, the cofunction identities state that the sine of one equals the cosine of the other and vice versa
<em>Example</em>
Suppose we have the right triangle ABC
The measure of angle C is 90 degrees
A and B are complementary angles
A+B=90°
therefore
sin(A)=cos(B)
sin(B)=cos(A)

Step-by-step explanation:
I'm guessing it's about 75 restaurants that have Hawaiian pizza on their menu. I just multiplied 7.5 by 10 because there are a 100 restaurants overall.
