Answer:

  • 59°

Step-by-step explanation:

A and B are complementary angles since C is right angle.

  • m∠A + m∠B = 90°
  • 31° + m∠B = 90°
  • m∠B = 90° - 31°
  • m∠B = 59°

Find l of the following cone ​
e-lub [12.9K]

Answer:

l =  \sqrt{261}\: in

Step-by-step explanation:

Height of the cone h = 15 in

Radius of the cone r = 12/2 = 6 in

We need to find slant height (l) =?

\because l =  \sqrt{ {r}^{2}  +  {h}^{2} }  \\  \\ \therefore l =  \sqrt{ {6}^{2} +  {15}^{2}  }  \\  \\\therefore  l =  \sqrt{36 + 225}  \\  \\\therefore  l =  \sqrt{261}  \\

A valve in a full 6000 gallon water tank is slowly opening. Water flows out of the tank through the valve. The flow rate in gall
Wittaler [7]
The volume of the gallon is 6000 gallon
the rate of water flow per min is f(t)=300t^2
a] amount of water that flowed in the first 7 minutes=7/60 hours will be:
f(7)=300(7/60)^2
solving the above we get
f(7)=7/12 gallons

b] The time taken for the tank to be empty will be as follows:
amount of water that will flow out for the tank to be empty will be 6000 gallons
thus,
6000=300t^2
this can be simplified to
20=t^2
t^2-20=0
solving this we get:
t=-2√5 or 2√5
the time taken for the tank to be empty will be t=2√5 hours=5.4721 hours

Please help me with this question!! Show steps

Answer: Slope is -1

Using the slope formula, we get

m = (y2 - y1)/(x2 - x1)

m = (0 - 4)/(2 - (-2))

m = (0 - 4)/(2 + 2)

m = -4/4

m = -1

What's going on here is that we subtract the y values 0 and 4 to get -4. This means that we dropped 4 units vertically to go from A to B. This is the rise. So rise = -4

The run is 4 because we moved 4 units to the right to go from A to B. This is found algebraically when we subtracted the x coordinates, so 2 - (-2) = 2 + 2 = 4.

Slope = rise/run = -4/4 = -1

You have the correct answer, assuming you wrote -1. I think your teacher just marked it wrong because you forgot to show steps.
