7π/12 lies in the second quadrant, so we expect cos(7π/12) to be negative.
Recall that
which tells us
Now,
and so
Answer:
x = 40
Step-by-step explanation:
.80x + 30 = 1.20x + 14
<u>-.80x = -.80x </u>
30 = .4x + 14
<u> -14 = -14</u>
16 = .4x
16/.4 = .4/.4x
40 = x
M/w=4/3
3m/4w=1
we know w=69
3m=4*69
m=4*69/3=92
92/69=4/3
Answer: f(x)= (3/4)^x/2 —> Decay
f(x)=(4/3)^x —> Growth
f(x)=(5/6)^3x —> Decay
f(x)=(8/3)^x/3 —> Growth
f(x)=(3/2)^2x —> Growth
Step-by-step explanation: When you graph them one by one, for example, the first equation (f(x)= (3/4)^x/2), the graph would have an asymptote on the right side, meaning that it’s decaying.
Straight up explanation: if the asymptote on the graph is on the left then it is growing, but if the asymptote is on the right then it’s decaying.
Asymptote is the “line” that almost touches the x axis.
Answer=103 ounces
First we need a conversion equations to get from pounds to ounces
1pound=16ounce
2pounds=2*16=32 ounces of cucumber
3pounds=3*16=48 ounces of lettuce
Now that all of the vegetables are in ounces, we can solve for their total weight.
x=32+8+48+15=103 ounces
He bought 103 ounces of vegetables in total.
