Answer:
it's answer is C. .80
Step-by-step explanation:
With reference angle A
base (b) = 8
Hypotenuse (h) = 10
Now
Cosine A
= b / h
= 8 / 10
= 0.8
Answer: Y= -2/3x -3
Explanation: The formula is y-y1=m(x+b).
Fill in what we know, which is,
y-(-5)=-2/3 (x-3) Then you distribute and get y+5=-2/3x+2. Then you subtract 5 from each side and get your final answer of y=-2/3x -3
Answer:
B
Step-by-step explanation:
I think the answer is B but I could be wrong! I'm 98% confident in my answer though!
Answer: f(0)=8
f(-2)=0
Step-by-step explanation:
f(0)=8+4(0)
f(0)=8+0
f(0)=8
f(-2)=8+4(-2)
f(-2)=8+(-8)
f(-2)=8-8
f(-2)=0
Answer:
(x+3)²-11=0
Step-by-step explanation:
0=9(x2+6x)-18
0= 9x² +54x-18
0= 9( x²+6x-2) taking 9 common
0= x² +6x-2 (breaking the mid term to find the second element of the square
0 = (x)² +2(x)(3) +(3)² -2 -9 adding and subtracting the second element
0= (x+3)² -11 summing up
