Step-by-step explanation:
Constant: -17
-> This is the number that doesn't change. No matter what m or p is, -17 will be -17
Coefficient: 7
-> The coefficient is the number next to the variable. In this case, the number "with" (being multiplied by) p is 7

A cone-shaped container is completely filled with liquid. The container has a radius of 60 cm and an height of 210 cm. The liquid is drained from the container at a rate of 1099 cm³ per hour. How many hours will it take to drain all of the liquid? Use 3. 14 to approximate pi. Enter your answer in the box. Hours.
Find the volume of the cylinder to know how much liquid is in it:
volume of a cylinder = Pi x r^2 x height.
Volume = 3.14 x 60^2 x 210
Volume = 2,373,840 cubic cm
now to find the length of time divide total cubic cm by the drainage rate:
2,373,840 / 1099 = 2,160 hours
Answer: 2,160 hours

how are the two coin stacks different from each other?
does either stack of coins resemble a geometric solid? if so which stack and what solid?
how do the heights of the two stacks compare?
how do the volume of the two stacks compare? explain your reasoning.
Question 1
You probably agree that it's fairly obvious that the stack on the right is slanted, while the stack on the left is straight up and down (more or less).
--------------
Question 2
The stack on the left resembles a cylinder. It might help to wrap the coins in a paper casing to better see this.
--------------
Question 3
The heights of each stack appears to be the same. This is assuming both stacks have the same number and type of coins.
--------------
Question 4
The two stacks have the same volume. This may seem a bit strange, but if both stacks have the same number and type of coins, then each of the individual coins has the same volume. When put together, the overall 3D solids will have the same volume as well. It doesn't matter if we slanted one of the stacks or not.
I- $8,950
R- 6.85%
T- 6 years
Answer:
$4,368
Step-by-step explanation:
This is compound interest. and to calculate compound interest, which is (Amount - Principal) but we dont know the value for amount so we find the amount first by using the formula.
A = P ( 1 + R ) ^n
100
where p = principal ($8,950)
a = amount (?)
r = interest rate (6.85%)
n = time ( no of years) (6)
A = 8,950 ( 1 + 6.85 ) ^6
100 A = 8,950 ( 1 + 0.0685) ^6
A = 8,950 ( 1.0685) ^6
A = 8950 x 1.4881 A = 13,318
WE THEN FIND COMPUND INTEREST C = A MOUNT - PRINCIPAL
13, 318 - 8950 = $4,368

how do i solve –1.8c + 5.1d for c = 2.9 and d = -4.2.
Answer:
See below
Step-by-step explanation:
-1.8c + 5.1d plug the numbers in that you were given.
-1.8(2.9) + 5.1(-4.2)
Multiply the first and second group of numbers
-1.8 x 2.9 = - 5.22
5.1 x -4.2 = - 21.42
Now add the two numbers together but remember they are both negative numbers. So when you add them together, it will end up being a more negative number.
-5.22 + -21.42 = - 26.64
Mr. Appleman own a rectangle apple orchard that measure 18m long and has a diagonal length of 25m. What is the width of his Orchard to the nearest the tenth of a metre?
Answer:
length = 17.3 m
Step-by-step explanation:
Rectangles have four right angles, so the diagonal and its sides will form a right triangle. This allows us to use the Pythagorean Theorem to find the length.
l^2 + 18^2 = 25^2
sqrt l^2 = sqrt (25^2 - 18^2), where l = 17.349 = 17.3 m

A rocket was launched into the air from a podium 6 feet off the ground. The rocket path is represented by the equation h(t)=-16t2+120t +6, where h(t) represents the height, in feet, and t is the time, in seconds. Find the average rate of change from the initial launch to the maximum height.
Answer:
60
Step-by-step explanation:
The given function is:
The average rate of change of h(t) from t=a to t=b is given by:
We can rewrite this function as:
The maximum height of the rocket is 231 and it occurs at t=3.75
The initial launch occurs at: t=0
and
The average rate of change from the initial launch to the maximum height is
The average rate of change from the initial launch to the maximum height is 59.21 ft/s.
We have a equation that represents the Rocket path.
We have to find the average rate of change from the initial launch to the maximum height.
What do you mean by a Time - varying quantity ?A time varying quantity is the quantity whose absolute value change with time. For example - y = f(t) = 2t - 1 , where y is the displacement and it varies as y = 2t - 1 with time.
According to the question, we have -
Equation → [tex]h(t) = -16t^{2} +120t+6[/tex]
Height of podium → 6 feet.
Initial velocity (u) = 0
Now -
[tex]h(t) = - 16t^{2} +120t+6[/tex]
Differentiating w.r.t time, we get →
[tex]$\frac{dh}{dt} = - 32t + 120[/tex]
For maximum height → [tex]$\frac{dh}{dt} = 0[/tex]
-32t + 120 = 0
32t = 120
t = 3.8 seconds
This means that at t = 3.8 seconds the rocket will reach its maximum height. Therefore, the maximum height will be -
h(t) = - 16 x 3.8 x 3.8 + 120 x 3.8 + 6
h(t) = - 231.04 + 456 + 6
h(t) = 224.96 + 6
h(t) = 230.96 = 231
The maximum height reached by the rocket is 231 feet's.
Now -
Initial height = 6 feet
Initial time = 0 s
Final height (max) = 231
Time at maximum height = 3.8
Therefore, the average rate of change from the initial launch to the maximum height will be -
[tex]$v_{avg} = \frac{231-6}{3.8-0}=59.21[/tex]
v (avg) = 59.21 ft/s
Hence, the average rate of change from the initial launch to the maximum height is 59.21 ft/s
