Without graphing the equations, decide whether the system has one solution, no solution, or infinitely many solutions.

Which scenario can the following graph describe? A)the total time a kite is up in the air as it goes up for a little bit ,comes

Vadim26 [7]

Answer:

Option C is the correct answer.

Step-by-step explanation:

We are given,

<em>A graph where the function first increases and then decreases to touch the x-axis and the increases.</em>

It is required to find the corresponding situations.

So, from the options we have that,

The graph represents the speed of a vehicle which first increases (as it accelerates), then decreases (slows down) and then touch the x-axis (stops at the light) and then increases (accelerates on the ramp for a freeway).

Hence, option C is scenario that the graph describes.

Union City Bakery uses a chocolate chip muffin recipe that yields 1/2 cup of milk for every batch of 12 chocolate chip muffins.

You need 1/24 of a cup to make one muffin you would need one cup of milk to make 24 muffins

Please help me on this!!

Mrac [35]

Answer:

Pretty sure it's "only i"

Step-by-step explanation:

A constant rate of change means that something changes by the same amount during equal intervals.

$30 is the same amount whereas 10% could vary.

Hope this helps.

Gravel is being dumped from a conveyor belt at a rate of 10 cubic feet per minute. It forms a pile in the shape of a right circu

Sunny_sXe [5.5K]

Answer:

0.0221 feet per minute.

Step-by-step explanation:

$\text{Volume of a cone}=\dfrac{1}{3}\pi r^2 h$

If the Base Diameter = Height of the Cone

The radius of the Cone = h/2

Therefore,

$\text{Volume of the cone}=\dfrac{\pi h}{3} (\dfrac{h}{2}) ^2 \\V=\dfrac{\pi h^3}{12}$

Rate of Change of the Volume, $\dfrac{dV}{dt}=\dfrac{3\pi h^2}{12}\dfrac{dh}{dt}$

Since gravel is being dumped from a conveyor belt at a rate of 10 cubic feet per minute. Therefore, the Volume of the cone is increasing at a rate of 10 cubic feet per minute.

$\dfrac{dV}{dt}=10$ ft^3/min$

We want to determine how fast is the height of the pile is increasing when the pile is 24 feet high.

We have:

$\dfrac{3\pi h^2}{12}\dfrac{dh}{dt}=10\\\\$When h=24$ feet$\\\dfrac{3\pi *24^2}{12}\dfrac{dh}{dt}=10\\144\pi \dfrac{dh}{dt}=10\\ \dfrac{dh}{dt}= \dfrac{10}{144\pi}\\ \dfrac{dh}{dt}=0.0221$ feet per minute$

When the pile is 24 feet high, the height of the pile is increasing at a rate of 0.0221 feet per minute.

The equation of the line goes through the points (0,5) and (10,0) expain what these points represents in the context of the situ

tamaranim1 [39]

Answer:

The equation would be y = -1/2x + 5

Step-by-step explanation:

To find the equation, we first need to use the slope formula.

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

m = (5 - 0)/(0 - 10)

m = 5/-10

m = -1/2

Now that we have that, we can use that and a point to find the full equation.

y - y1 = m(x - x1)

y - 0 = -1/2(x - 10)

y = -1/2x + 5
