A large solar panel can generate power at a maximum rate of 400400400 kilowatts per day. It generates power at a constant rate w
kobusy [5.1K]

For a Cloudy sky , the solar panel requires 80 hours to generate 400 kilowatts per day

For a clear sky the solar panel requires 12.5 hours to generate 400 kilowatts per day.

The solar panel does not exceed its maximum capacity of 400 kilo watts per day because it will generate 207 kilo watts per day.

Step-by-step explanation:

1.Given the inequality for power generated as;

5C+32L≤400 where C is number of hours when sky is cloudy and L is the number of hours when the sky is clear then;

The equation can be written using x and y as

5x + 32 y ≤ 400 -----where x=C and y=L

Graphing the equation on a graph tool for values of x and y that produce maximum capacity,the graph is attached below where x=80 hours and y=12.5 hours.

This means C=cloudy sky = 80 hours and L=clear sky= 12.5 hours

For a Cloudy sky , the solar panel requires 80 hours to generate 400 kilowatts per day

For a clear sky the solar panel requires 12.5 hours to generate 400 kilowatts per day.

2.

Given C=3 hours and L= 6 hours substitute values in the inequality

5C+32L≤400

5*3 + 32*6 ≤ 400

15+192 ≤ 400

207 ≤ 400

The solar panel does not exceed its maximum capacity of 400 kilo watts per day.

Answer:

option 3

Step-by-step explanation:

Standard \ quadratic \ equation : ax^2 + bx +c

Larger the value of  '' a '' makes the parabola narrow.

A positive value of '' a '' which is close to 0 makes the parabola wide.

<em><u>To find the widest graph , find the smallest </u></em><em><u>a</u></em><em><u>. (or </u></em><em><u>a</u></em><em><u> closest to zero)</u></em>

option 1

     a_1 = \frac{1}{3}

option 2

     a_2 = - \frac{4}{5}

option 3

     a_3 = 0.3 = \frac{3}{10}

option 4

     a_4 = -4

Positive and negative value of ' a ' decides the direction the parabola opens.

But we have to find the widest parabola irrespective of the direction.

So we will find the smallest  ' a '

                                a_1 = 0.33\\a_2 = 0.80\\a_3 = 0.30\\a_4 = 4

a_3 \ is \ the \  smallest \  number \  or\ \\ the \  number \  closest \  to\  zero.\\\  so \  option \ 3 \ makes\  the\  widest \ parabola.

Answer:

1/2 of 6/7 is greater than 2/3 of 3/7

Step-by-step explanation:

6/7 x 1/2 = 6/14 = 3/7

3/7 x 2/3 = 6/21 = 2/7

2/7 < 3/7

1/2 of 6/7 is greater than 2/3 of 3/7

Can someone help me answer a few of these? Thank you! :)
sesenic [268]
I’m going to try to answer these to the best of my ability.

1. Plane D
2. Plane C
3. AB
4. No
5. I don’t believe so because it doesn’t look like C is on the same plane as a AB and D.
6. I think so, yes! Collinear means that they are on the same line, and it looks like if you put a line between those two to connect them, they would connect perfectly!
7. B possibly? Because it looks like B, C, and D are all collinear and that they would pass through a straight line. A doesn’t look like it’s collinear with the rest of them.
8. No
9. Yes
10. Yes

I’m sorry if any of those are wrong, but I did make sure to try and put some explanations for some of them so you saw why I gave the answer that I gave! I hope that helped and like I said, I’m sorry if any of them are wrong, I tried my best!
