Answer:
The value of k is -11
Step-by-step explanation:
If (x+2) is a factor of x3 − 6x2 + kx + 10:
Then,
f(x)=x3 − 6x2 + kx + 10
f(-2)=0
f(-2)=(-2)³-6(-2)²+k(-2)+10=0
f(-2)= -8-6(4)-2k+10=0
f(-2)= -8-24-2k+10=0
Solve the like terms:
f(-2)=-2k-22=0
f(-2)=-2k=0+22
-2k=22
k=22/-2
k=-11
Hence the value of k is -11....

Answer:
∠KYR = 43 degrees
Step-by-step explanation:
1. We know that the entire angle equals to 90 degrees because it is a right angle.
First you have to find the value of c and to do this, you add the values of both angles and make it equal to 90
3c + 64 + 5c + 82 = 90]
8c + 146 = 90
- 146 -146
8c = -56
c = -7
Now we have to find the value of angle KYR so just plug in -7 for c
3(-7) + 64 = 43

Answer:
Step-by-step explanation:
Let's start by decoding this :)
First lets do 60% more than 10; 16 (mental math)
Next, lets do 20% less than 16; x/16 = 80/100 (Equation)
After solving by cross multiplying & then simplifying (make sure both denominators are 100), you should get 12.8 as your final #! Hope this helped.
