Answer:
E.) 1
Step-by-step explanation:
Firstly we will solve for L.H.S.
L.H.S. =
Since we know that
is the inverse of
.
So we can say that;

Now For R.H.S.

Since we can rewrite
as
.
Now we can say that the R.H.S. is;

Now we add the fraction and get;

Now according to trigonometric identity;

So, 
Here,
and
=
<em> </em>
L.H.S. = R.H.S.
Hence 
Answer:
The answer is 80 degrees, I believe
Start by finding out how much he sold on the two days. That will be;
Monday: 1/3 x 30= 10 cards
Tuesday: 3/2 x 30= 45 cards
From the above, you can see that he sold more than 30 cards on Tuesday. But less than 30 on Monday. So the correct answer is H.
He sold fewer cards than his goal on Monday and more cards than his goal on Tuesday. Hope I helped. Good luck
Answer:
Results are below.
Step-by-step explanation:
<u>First, we need to establish the decrease function in the given population:</u>
FV= PV/(1+g)^n
FV= future value
PV= present value
g= decrease rate
n= number of periods
<u>Now, for the given information:</u>
<u></u>
PV= 330
g= 22% = 0.22
n= 5 years
FV= 330 / (1.22)^5
FV= 122
Let x and y be islands and peninsulas respectively
x+y=191919
2x+3y=454545
y = 191919- x
2x + 3 (191919 - x) = 454545
2x + 575757 - 3x = 454545
2x-3x = 454545 - 575757
-x = -121212
x = 121212
121212 + y = 191919
y = 191919 - 121212
y = 70707
Ni Hua visited 121212 islands and 70707 peninsulas
