Answer:

The correct answer is "4500".

Explanation:

As per the question,

Total galloons of water will be:

=  \int_{0}^{2}250 t \ dt+\int_{2}^{10}500 \ dt

=  250(\frac{t^2}{2} )^2_0+500(t)^{10}_2

=  125(4-0)+500(8-2)

=  125(4)+500(6)

=  500+4000

=  4500

Thus the above is the appropriate option.

4. Suppose the house in question 3 is located in Cleveland where the annual average solar flux is 160 W/m2 2. If 10 m2 of solar
Ahat [919]

Answer:

Solar flux that incident on it is given as

S = 160 W/m/m

Now we know that the area of solar panels is given as

A = 10 m^2

So total solar power received by solar panels is given as

Power Received = (Solar flux) \times (Area)PowerReceived=(Solarflux)×(Area)

P = S\times AP=S×A

now here we have

P = 160 \times 10P=160×10

P = 1600 WP=1600W

now we know that efficiency of the solar panels is 20%

so total output power will be

efficiency = \frac{P_{out}}{P_{in}}efficiency=

A "point" is 1% of your borrowed amount on a mortgage. You want to pay 2 points to get a 0.5% reduction in your interest rate on
igor_vitrenko [27]
The answer is $3500.

You are simply asking for the equivalent of 2 points for the mortgage of $175,000. Since 1 point is equal to 1% of the mortgage, 2 points is 2% of the mortgage then.

Equation:
Y = P% * X
Y = 2% * 175000

Convert P into decimal: P = 2/100 = 0.02

Y = 0.02 * 175000
Y = 3500
