Answer:
24m^2+50m-14
Step-by-step explanation:
X = 12
27x - 45 = 18x + 63
-18x
9x - 45 = 63
+45
9x = 108
108/9
Answer:
k=9
Step-by-step explanation:
First find r=22/20=1.1
The sum of the first k terms formula is a1•(1-r^k)/(1-r)
a1=20 and the sum is 271.59
Now plug in these values in the formula and find k.
271.59=20(1-1.1^k)/(1-1.1)
When you simplify this equation, you will get k=ln(2.358)/ln(1.1)
k=9
Answer:
0.9950 to the nearest ten thousandth.
Step-by-step explanation:
We use the identity sin^2 t = 1 - cos^2 t
sin^2 t = 1 - (0.1)^2
= 0.99
So sin t = 0.9950 (answer).
