Answer:

ezzz all u got to know is that counterclockwise is left and clockwise is right they want counter clockwise so u turn the paper left and u do it using the middle cuz origin means middle in math and the middle if u did not know is 0 the point 0 so the answer would be (3,7) cuz when u turn the paper left using the origin it ends up going to the positive side

Step-by-step explanation:sry if u don’t get It I tryed to explain it the best that I could it’s so ez tho I hope ur in a lower grade then me cuz if ur higher I’ll be sad to hear that it’s ez

Find the values of x and y that maximize the objective function P=3x+2y for the graph. What is the maximum value?

AURORKA [14]

Answer:

(9, 0)

Step-by-step explanation:

Maximum or minimum value occurs at the Corner. The points given are (0, 8), (5, 4) and (9, 0).

Substitute (0, 8) in the objective function.

We get P = 3(0) + 2(8) = 16

Now for (x , y) = (5, 4)

P = 3(5) + 2(4) = 15 + 8 = 23

At (9, 0) we get P = 3(9) + 2(0) = 27.

Clearly, we have the maximum value at (9, 0).

And the maximum value is 27.

The key feature of the functions that are needed to determine if the lines intersect are;

The slope; rate of change
The y-intercept

<h2>Slope and y-intercept</h2>

From straight line geometry, we can conclude that two parallel lines whose slope are equal can never intersect.

On this note, for the functions described in the question, the functions only intersect when the slopes are different.

Additionally, the functions may intersect in the event of having equal y-intercepts.

In order two straight lines in a coordinate plane intersect, they MUST have different slopes.

This condition is NECESSARY and SUFFICIENT.

An hourglass consists of two sets of congruent composite figures on either end. Each composite figure is made up of a cone and a

belka [17]

Answer: third option 268.8

Explanation:

For this kind of proble it is very important that you attach the figure because it contains important information to understand the question.

I have attached the figure for better understanding.

1) The top portion (and the bottom is congruent but rotated 180°) of the hourglass is a figure equivalent to a cylinder on top and a cone on bottom.

So the total volume contained in the top portion is the volume of a cylinder + the volume of a cone.

This is how you calculate the volume of the top portion:

1) The height of the cylinder is 54 mm - 18 mm = 36 mm

2) The formula for the volume of a cylinder is V = π (radius)^2 * height

radius = 8 mm
height = 36 mm

=> V = π(8mm)^2 * 36 mm = 2304π (mm)^3

3) The formula for the volume of a cone is V = (1/3)π(radius)^2 * height

radius = 8 mm
height = 18 mm

V = (1/3)π(8mm)^2 * 18 mm = 384π (mm)^3

4) The total volume of the top portion is volumen of the cylindrical part + voume of the cone:

Total voluem = 2304π (mm)^3 + 384π (mm)^3 = 2688π (mm)^3

5) To find the number of seconds it take until all of the sand has dripped to the bottom of the hourglass you have to divide the total volumen of sand by the rate:

time in seconds = total volume of sand / rate of dripping

time in seconds = [2688 π (mm)^3 ] / [10π (mm)^3 / s] = 268.8 s

That is the answer: 268.8 s
