If you have two fractions that you want to multiply . . .
-- The product of the two numerators is the numerator of the product.
-- The product of the two denominators is the denominator of the product.
Answer:
1) B
2) a. 5x-7 b. 15b + 25 c. 16x^2 + 4x d. 13g -20. e. 6h + 23
Step-by-step explanation:
I’m sorry if any of them are wrong but I believe they’re right, most of it was distribution
Answer:
a) dm/dt = 0.2m
b) ln(m) = 0.2t + A
c) ln(m) = 0.2t + ln(20) - 0.6
d) 11 grams
Step-by-step explanation:
a) dm/dt = 0.2m
b) dm/m = 0.2dt
ln(m) = 0.2t + A
c) At t = 3, dm/dt = 4
dm/dt = 0.2m
4 = 0.2m
m = 4/0.2 = 20
So, when t = 3, m = 20
ln(20) =0.2(3) + A
A = ln(20) - 0.6
ln(m) = 0.2t + ln(20) - 0.6
d) find m when t=0
ln(m) = 0.2(0) + ln(20) - 0.6
ln(m) = ln(20) - 0.6
ln(m) = 2.3957322736
m = e^2.3957322736
m = 10.9762327224
m = 11
In quadrant I, when sin angle is 1/2, cos angle is (sqrt3)/2
