Answer:

The correct options are 1 and 4.

Step-by-step explanation:

The given equation of line is

y+6=-10(x-3)                   .... (1)

The point slope form of a line is

y-y_1=m(x-x_1)               ..... (2)

Where m is the slope of line and (x₁,y₁) are points.

On comparing (1) and (2) we get

m=-10,x_1=3,y_1=-6

The slope of given line is -10 and the line passing through the points (3,-6).

Therefore correct options are 1 and 4.

The slope of the line is -10
y+6=-10(x-3)
y=-10(x-3)-6
y=-10x+30-6
y=-10x+24
slope is y=mx+b where m=slope

one point on the line is (3,-6)
y=-10x+24, plug 3 in for x
y=-10(3)+24
y=-30+24
y=-6

An observer stands 25 feet from the base of a flagpole and watches a flag being lowered at a rate of 5 ft/sec. Determine the rat
Sedaia [141]

Answer:

0.1 rad/s

Step-by-step explanation:

Since the distance from or to the flagpole is not given, I will assume. And my assumption is 50 ft

Now, the elevation angle A = 45 degrees, converting to radians, we have π/4 radians

Remember that the tan of an angle is OPP/HYP, and so

tan A = h/25, on differentiating, we have

d tan A/dA = sec^2 A = (1/25) dh/dA

Next, we have

25 sec^2 A * dA/dt= dh/dt = 5

Making dA/dt the subject of formula, we have

dA/dt = (1/5) cos^2 A

but cos^2 A from trigonometry = 1/2, this means that

dA/dt = .1 radians/second

If you want to convert to degrees, your have

.1 Rad/s( 180 deg/rad) = 18 degrees/second

Whats the perimeter and area of this shape?
stich3 [128]

Answer:

<u>60+14.35=88.27</u>

Step-by-step explanation:

5x12 for the rectangle on the right, then for the circle, using the formula A=πr², I get 28.27, which you divide by 2 because you only need half of the circle, and you get 88.27. I calculated the radius by subtracting 12-6 and then dividing that in half because the radius is half of the distance to the other end of the circle. Then you get the radius of 3, then plug it into the formula to get π(3)², which is just 3.14(9), and you get 28.27.

Which point below is not on the graph of p(x) = +36- X?
natka813 [3]

Answer:

We have the following equation: y = 36 - x. And we need to find which of the following points belong to the graph:

  • (-13,7)
  • (-35, 1)
  • (11,5)
  • (27,3)

If any of the points belong to the equation, then the equality will be met.

Then:

  • (-13,7) :

7 = 36 - (-13)

7 = 36 + 13

7 = 49 ❌

  • (-35, 1) :

1 = 36 - (-35)

1 = 71❌

  • (11, 5) :

5 = 36 - 11

5 = 25 ❌

  • (27,3)

3 = 36 - 27

3 = 9 ❌

None of the points belong to the graph. Therefore, all points are NOT on the grah of p(x) = 36 - x.
