First we convert the tiles to expressions. Similar tiles can be summed up and written as one term. For example 2 tiles of x can be written as 2x.

So we are to add $x^{2} +x$ to $2x+3$ .

The summation will be:

$x^{2} +x+2x+3 \\ \\ = x^{2} +3x+3$

Therefore, option B is the correct answer.

Formula for volume of cone:

V = $\pi r^{2} \frac{h}{3}$

r = 6 km

h = 12 km

V = $\pi 6^{2} \frac{12}{3}$

V = $\pi 36*4$

V = $\pi 144$

V = 452.389 km^3 <----------------------Using the calculators pi button

V = 452.16 km^3 <-------------------------Using 3.14 for pi

Hope this helped!

kicyunya [14]

If there were a total of 21 games played over 3 months, you divide 21 by 3.

Your answer is 7 games were played each month.

The information about how many games were played at night is useless. It's just thrown in there to confuse you. :)

The water level of a certain body of water is changing at a rate of W(t)=3/4cos(4-t/2) inches per hour, where t represents hours

Leni [432]

Answer:

The answer is below

Step-by-step explanation:

a) The integral $\int\limits^{10}_{1 } {W(t)} \, dt$ means the total change in level of water in inches from 1 am to 10 am. That is the water level change measured in inches between 1 am and 10 am

b) 7 pm is represented as t = 19 hours, while midnight is represented as t = 24 hours, hence the water level change between 7 pm and midnight is:

$\int\limits^{24}_{19 } {W(t)} \, dt\\\\$

c) Using casio calculator to evaluate the integral gives:

$\int\limits^{24}_{19 } {W(t)} \, dt\\\\$ = 2.54 inches

D) The total daily change in water level = $\int\limits^{24}_{0 } {W(t)} \, dt\\\\$ = 0.35 inches
