Answer:
18
Step-by-step explanation:
0.5(w) + 3x
0.5(6) + 3(5)
= 18
You use the slope formula, (y2-y1/x2-x1)
Answer:
Given,
A=90
b=15
A=12bh
Now,
Step-by-step explanation:
Put the given value in the formula
A=12bh
90=12*15*h
90=180h
90/180=h
Hence, h=0.5
Answer:
1.107 = r
Step-by-step explanation:
To solve this for r, do the following:
Add 10 to both sides, to isolate the r term on the left: 18r^(-8) = 8
Divide both sides by 18, to isolate r^(-8): r^(-8) = 8/18
Invert both sides: r^8 = 9/4
Take the natural log or both sides:
8 ln r = ln 9 - ln 4, or
8 ln r = 0.8109, so that ln r = 0.1014
to find r, raise e to the power ln r on the left and e to the power 0.1014 on the right:
ln r 0.1014
e = e = 1.107 = r
Answer:
d 13
Step-by-step explanation:
Subtracting means adding the opposite.
To subtract -4, you add the opposite of -4 which is 4, so you add 4.
9 - (-4) = 9 + 4 = 13
Answer: d 13
