Dr Leon is a chiropractor who offers house calls to his patients. He uses the function c(m) = 26m + 60 to calculate the total medical bill ( in dollars) ,c( m) , for each 20 - min session,m. During the holidays, Dr Leon changes his total medical bill function to c(m) = 35m + 45.

Answer:

C. 9

Step-by-step explanation:

as the line BE and CD are parallel

AB/BC = AE/ED

=> 5/3 = 15/x

=> 5x = 15×3

=> 5x = 45

=> x = 45/5

=> x = 9

Answer:

AME = 20°

Step-by-step explanation:

We know that there are four right triangles so AOM = 90. We know that OAM = 70 and the total degrees in a single triangle is 180 With that information, we can create an equation and solve for AME.

90 + 70 + AME = 180

160 + AME = 180

AME = 20°

Answer:

The blue point is at -15.

Step-by-step explanation:

It's counting by 3's. 3, 6, 9, 12, 15...

Form A

H(t) = -8(t – 2)² + 37

Form B

H(t)= -8t² + 32t + 5

a. From form A, the vertex of the parabola is at (2, 37). This means that the maximum height is 37 feet and it's reached after 2 seconds.

b. The initial height corresponds to t = 0 seconds. Replacing t = 0 into form B:

H(0)= -8(0)² + 32(0) + 5 = 5 ft

That is, the initial height was 5 ft

Answer:

DB = approximately 16

Step-by-step explanation:

DEC is a right triangle => DC=10. Because all four sides are equal in a rhombus, then AD=AB=10. Then, because angle BAD is 53*2=106 degrees, we can use cosines. DB=sqrt(10^2+10^2-2*10*10cos(106deg))=15.9727102009.

The coordinates of the vertices of the triangle after the translation are:

A' = (8, 3)

B' = (1, 3)

C' = (-1, 0)

To find the coordinates of the vertices after the given translation, you need to apply the translation to each vertex of the triangle.

Let's denote the original vertices of the triangle as follows:

A = (4, 5)

B = (-3, 5)

C = (-5, 2)

The translation vector is (4, -2).

To apply the translation to each vertex, you simply add the components of the translation vector to the corresponding components of the original vertices.

For vertex A:

A' = (x + 4, y - 2)

= (4 + 4, 5 - 2)

= (8, 3)

For vertex B:

B' = (x + 4, y - 2)

= (-3 + 4, 5 - 2)

= (1, 3)

For vertex C:

C' = (x + 4, y - 2)

= (-5 + 4, 2 - 2)

= (-1, 0)

Therefore, the coordinates of the vertices of the triangle after the translation are:

A' = (8, 3)

B' = (1, 3)

C' = (-1, 0)

The point on the number line that represents the probability of rolling an even number and selecting a green marble is 3/8, which is between 0.3 and 0.4 on the number line.

Will she land on an even number and then selects agreen marble?

The probability of rolling an even number is 3/6, which can be simplified to 1/2, because there are three even numbers (2, 4, and 6) out of six possible outcomes.

The probability of selecting a green marble from the bag is 3/4, because there are three green marbles out of four total marbles in the bag.

To calculate the probability of both events happening together (rolling an even number and selecting a green marble), you multiply the probabilities of each event:

P(even number and green marble) = P(even number) x P(green marble)

P(even number and green marble) = (1/2) x (3/4)

P(even number and green marble) = 3/8

Positive correlation means that both variables tend to increase (or decrease) together. Thus, Option A is the answer.

Positive correlation refers to a relationship between two variables in which an increase in one variable is associated with an increase in the other variable. Negative correlation, on the other hand, refers to a relationship in which an increase in one variable is associated with a decrease in the other variable. No correlation means that there is no relationship between the two variables.

To determine the strength of a correlation, we can use a statistical measure called the correlation coefficient, which ranges from -1 to 1. A correlation coefficient of 1 indicates a perfect positive correlation, a correlation coefficient of -1 indicates a perfect negative correlation, and a correlation coefficient of 0 indicates no correlation.

The lower and the upper limit for a 99% confidence interval would be approximately 37.51 and 50.03

Here,

Mean = 43.77

Standard deviation (s)= 12.43655

n= 30

So,

   CI= mean ± t (s/√n)

      = 43.77±2.756(12.43655/√30)

      = 43.77±6.26

The values of d that make the inequality 9d > 9 true are given as follows:

2, 4, 11.

Hence the equivalent inequality is given as follows:

d > 1.

The inequality in the context of this problem is defined as follows:

9d > 9.

(an inequality is solved similarly to an equality, isolating the desired variable, the difference is that the solution is composed by infinity values on an interval instead of a finite number of exact values).

To solve the inequality, we solve it similarly to an equality, isolating the desired variable d, hence the solution is given as follows:

d > 9/9 -> division is the inverse operation of multiplication.

d > 1.

The > symbol means that the solution is composed by values that are greater than 1, hence the options are 2, 4, 6 and 11.

Now, we use the quadratic formula to find the solutions.

Where a = -5, b = -2, and c = 32.

In this case, just the positive solution makes sense.

We are given –

We are asked to find volume of the given cylinder.

Let the radius be "r".Then according to the question,it’s given –

\(\qquad\) \(\pink{\twoheadrightarrow\bf Curved\: surface\: area _{(Cylinder)}= 2\pi r h }\)

\(\qquad\) \(\twoheadrightarrow\sf 2\pi r h = 24 \pi\)

\(\qquad\) \(\twoheadrightarrow\sf 2\cancel{\pi} rh = 24 \cancel{\pi}\)

\(\qquad\) \(\twoheadrightarrow\sf r =\dfrac{24}{2h}\)

\(\qquad\) \(\twoheadrightarrow\sf r = \dfrac{24}{2\times 4}\)

\(\qquad\) \(\twoheadrightarrow\sf r = \dfrac{24}{8}\)

\(\qquad\) \(\twoheadrightarrow\sf r = \cancel{\dfrac{24}{8}}\)

\(\qquad\) \(\pink{\twoheadrightarrow\bf r = 3 \: cm}\)

Now, Let's find volume of cylinder

\(\qquad\) \(\purple{\twoheadrightarrow\bf V_{(Cylinder)} = \pi {r}^{2}h}\)

\(\qquad\) \(\twoheadrightarrow\sf V_{(Cylinder)} = \pi \times 3^2\times 4 \)

\(\qquad\) \(\twoheadrightarrow\sf V_{(Cylinder)} = \pi \times 9 \times 4\)

\(\qquad\) \(\twoheadrightarrow\sf V_{(Cylinder)} = \pi \times 36\)

\(\qquad\) \(\purple{\twoheadrightarrow\bf V_{(Cylinder)} = 36 \pi \: cm^3}\)

Step-by-step explanation:

Given :-

to find :-

Solution :-

Lateral surface area of cylinder = 2πrh

24π cm = 2πrh

Cancelling π on both the sides ,

24/2h = r

putting the value of h i.e, 4 cm

24/2×4 cm = r

3 cm = radius

Now volume of Cylinder = πr²h

putting all the values ,

Volume = 3.14 × 3² × 4 cm³

Volume = 113.04 cm³

Think of a parallelogram as a rectangle bended on its side. In this case, the rectangle is being bended from the right to the left. However, in this transformation, the area of the shape remains the same.

As such, you can apply the equation for the area of a rectangle here, Area = length * width.

However, now we are using different measurements. We have the base and the height of the parallelogram given.

The base acts as the width of the original rectangle. For reference, the top and bottom lengths of the rectangle were not changed as we were bending it into a parallelogram.

We also have the height given. Now, the left and right side lengths of the bended shape were changed. However, I want for you to conceptualize this, feel free to take out a piece of paper if it helps.

Draw out a rectangle that's longer left-to-right. Draw a bold line getting the height of the rectangle from one of the horizontal sides. Now, draw another bold line upwards through the middle of the rectangle. How do the bold lines compare? Are they the same?

Now, back to the example of the warping rectangle. When we're moving it towards the left, the left-right side lengths of the shape change. However, we can still get the height by drawing through the middle of the shape, which remains constant.

As such, we can confidently apply the area of a parallelogram formula,

Area = base * height.

The base acts as the width and the height acts as the length.

Area = 18 3/4 ft * 22 1/2 ft

Apply the foil approach (First terms, Outer terms, Inner Terms, Last Terms):

Let a, b, c, d all equal some number. In this case, we can represent 18 3/4 as 18 + 3/4, representing variables a and b. We can do the same with 22 1/2.

Answer = a + b * c + d

Answer = (a+b) * (c+d)

Answer = ac + ad + bc + bd
