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

Answer: The probability she gets at least one right is 1 minus this, or 0.988470785. In other words, she has an approximately 99% chance of getting at least one right.

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

Answer:

a) (2,9); b) no points of intersection

Step-by-step explanation:

a)

Set the two equations equal to each other

7x - 5 = -2x + 13

Rearrange collecting like terms and solve

9x = 18

x = 2

Sub in x = 2 into either of the equations and it should yield the same result

Eq.1 y = 7(2) - 5 = 9

Eq.2 y = -2(2) + 13 = 9

Therefore the point of intersection is (2,9)

The graph confirms this result (see graph 1 with red and blue lines)

b)

As the gradients are the same, we can tell straight away that the two lines should be parallel and never intersect, but we'll try to solve it algebraically using the same method as in part a.

3x - 1 = 3x + 2

When rearranging, the x's cancel out which can be seen when subtracting 3x from both sides

-1 = 2

This equation is clearly incorrect. This means that there are no values of x at which the two equations are equal. Graphically, this means that the two lines are parallel and there are no points of intersection (see graph 2 with purple and green lines)

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.

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

Answer:

Constant: -17

Coefficient: 7

Number of terms: 3

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

Number of terms: 3

-> There are three terms. A term includes positive/negative, number, variables, etc.

-> The terms are:

Perimeter of the figure = 26.5 m

Area of the figure = 59.68 m².

Perimeter of a figure is the length around the borders of the figure.

Find the Perimeter of the Figure:

Perimeter = 3.9 + 7.4 + 10.6 + 4.6 = 26.5 m

Area of the Figure:

Decompose the figure into two rectangles, rectangle 1 and rectangle 2.

Area of rectangle 1 = length × width = 10.6 × 4.6 = 48.76 m².

Area of rectangle 2 = length × width = 3.9 × (7.4 - 4.6) = 10.92 m².

Area of the figure = 48.76 + 10.92 = 59.68 m².

Answer:

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

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.

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
