Answer:

E.) 1

Step-by-step explanation:

Firstly we will solve for L.H.S.

L.H.S. = $Csc^2\theta$

Since we know that $Csc^2\theta$ is the inverse of $Sin^2\theta$ .

So we can say that;

$csc^2\theta=\frac{1}{sin^2\theta}$

Now For R.H.S.

$Cot^2\theta+1$

Since we can rewrite $cot^2\theta$ as $\frac{cos^2\theta}{sin^2\theta}$ .

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

$\frac{cos^2\theta}{sin^2\theta}+1$

Now we add the fraction and get;

$\frac{cos^2\theta+sin^2\theta}{sin^2\theta}$

Now according to trigonometric identity;

$cos^2\theta+sin^2\theta=1$

So, $\frac{cos^2\theta+sin^2\theta}{sin^2\theta}=\frac{1}{sin^2\theta}$

Here,

$csc^2\theta=\frac{1}{sin^2\theta}$ and $Cot^2\theta+1$ = $\frac{1}{sin^2\theta}$ <em> </em>

L.H.S. = R.H.S.

Hence $csc^2\theta=cot^2\theta+1$

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

Write an exponential function to model the situation. Then find the value of the function after 5 years to the nearest whole num

ludmilkaskok [199]

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

Ni Hua is an adventurous traveler. He skydives twice in every island he visits and skydives thrice in every peninsula he visits.

solniwko [45]

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
