Points X, Y, And Z Are Colinear.xWhat Is The Slope Of YZ In Simplest Form?[?]

Answers

Answer 1

The slope of a segment can be calculated by dividing the rise (change in the vertical direction) and the run (change in the horizontal direction).

Looking at the segment YZ, the horizontal distance is 3 units and the vertical distance is 6 units.

Therefore the slope is:

[tex]\begin{gathered} m=\frac{\text{rise}}{\text{run}} \\ m=\frac{6}{3} \\ m=2 \end{gathered}[/tex]

The slope of YZ is equal to 2.

We are given a right triangle labelled ABC. The sides indicated are;

[tex]\begin{gathered} Shorter\text{ }leg=m \\ Hypotenuse=(11+7)=18 \end{gathered}[/tex]

Also extracted from this triangle we have a smaller right triangle labelled BDC. The sides are labeled;

[tex]\begin{gathered} Shorter\text{ }leg=7 \\ Hypotenuse=m \end{gathered}[/tex]

We will begin by recalling the Pythagoras theorem which states;

[tex]\begin{gathered} Pythagoras\text{ }Theorem: \\ c^2=a^2+b^2 \end{gathered}[/tex]

Where c is the hypotenuse and a and b are the other two legs.

We can find the ratio between both triangles, because they are both similar by virtue of sharing one common side, that is side BD.

Hence, we will have;

[tex]\begin{gathered} For\text{ }\Delta ABC \\ BC=Shorter\text{ }leg \\ AC=Hypotenuse \\ For\text{ }\Delta BDC \\ DC=Shorter\text{ }leg \\ BC=Hypotenuse \end{gathered}[/tex]

We can now set up the following equation;

[tex]\frac{BC^2}{AC^2}=\frac{DC^2}{BC^2}[/tex]

We now have;

[tex]\frac{m^2}{18^2}=\frac{7^2}{m^2}[/tex]

We can cross multiply and we'll have;

[tex]m^2\times m^2=18^2\times7^2[/tex][tex]m^4=324\times49[/tex][tex]m^4=15876[/tex]

Next we take the square root of both sides;

[tex]\sqrt{m^4}=\sqrt{15876}[/tex][tex]m^2=126[/tex]

We take the square root of both sides yet again;

Find the circumference of each circle. Use ( pie symbol) as 22/7 Number 10. 1 1/3

Answers

ANSWER :

The circumference is 88/21 inches or 4.19 inches

EXPLANATION :

From the problem, we have a circle with a diameter of 1 1/3 in.

Note that the circumference of a circle is :

[tex]C=2\pi r\quad or\quad C=\pi D[/tex]

Since we have a diameter, we will use the second formula :

The circumference will be :

[tex]\begin{gathered} C=(\frac{22}{7})(1\frac{1}{3}) \\ C=(\frac{22}{7})(\frac{4}{3}) \\ C=\frac{88}{21}\quad or\quad4.19 \end{gathered}[/tex]

Given:

The cost price of the deck of cards is $72.78 dollars.

Mark up percent is 5%.

a) To find the amount of mark up:

So, we can write it as,

[tex]\begin{gathered} 5\text{ \% of 72.78=}\frac{5}{100}\times72.78 \\ =\text{ \$}3.639 \end{gathered}[/tex]

Thus, the amount of mark-up is $3.64 (rounded to the nearest hundredth).

b) To find the new price:

The new price = Cost price + Amount of mark up

So, we get,

[tex]\begin{gathered} =72.78+3.64 \\ =76.42 \end{gathered}[/tex]

Thus, the new price is $76.42.

a box has a length of 6X inches the width equal 1/3 the lamps in the height equals half the length of the volume equals 972 cubic inches what does x equal?

Answers

The length of the box is 6x inches

The width of the box is 1/3 of the length, that is:

1/3 * 6x = 2x inches

The height of the box is 1/2 of the length, that is:

1/2 * 6x = 3x inches

The volume of the box is 972 cubic inches.

The volume of a box (rectangular box) is given as:

V = L * W * H

where L = length, W = width, H = height

This means that:

V = 6x * 2x * 3x

[tex]\begin{gathered} 972=36x^3 \\ \Rightarrow x^3\text{ = }\frac{972}{36} \\ x^3\text{ = 27} \\ \Rightarrow\text{ x = }\sqrt[3]{27} \\ x\text{ = 3} \end{gathered}[/tex]

what is the constant of proportionality of: y= 6.28x

Answers

The constant of proportionality is the number that relates two variables. In this case the variables are "x" and "y", we need to find which number multiplies the value of "x" and results in "y". In this case it is "6.28". The constant of proportionality on a linear equation is always the number multiplying x.

The answer is 6.28.

In a recent year, 16.8% of all doctors were female. If there were 57,600 female registered doctors that year, what was the total number of registered doctors?Round your answer to the nearest whole number.

Answers

From the problem statement, we can say,

16.8% of total doctors is 57,600.

16.8% in decimal is

16.8/100 = 0.168

Let total number of doctos be "d", thus we can write the statement "16.8% of total doctors is 57,600" as >>>

[tex]0.168\cdot d=57600[/tex]

Now, we can solve for "d", shown below:

[tex]\begin{gathered} 0.168d=57600 \\ d=\frac{57600}{0.168} \\ d=342857.14 \end{gathered}[/tex]

Supposed that the future price p(t) of a certain item is given by the following exponential function.inthis function, p(t) is measured in dollars and t is the number of year's from today. p(t)= 2500 (1.026)t

Answers

Answer:

Initial price of the item = 2500

The function represents growth

The percent by which the price changes each year is 2.6%

Explanation:

The given function is expressed as

P(t) = 2500(1.026)^t

Recall, the exponential growth function is expressed as

P(t) = Po(1 + r)^t

where

Po is the initial value

P(t) is the future value

r is the growth rate

By comparing both functions,

Po = 2500. Thus,

Initial price of the item = 2500

Also,

1 + r = 1.026

Since 1.026 is greater than 1,

The function represents growth

r = 1.026 - 1

r = 0.026

This means that the growth rate is 0.026. We would convert it to percentage by multiplying by 100. It becomes

0.026 x 100 = 2.6%

The percent by which the price changes each year is 2.6%

Let the sample space be S = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10). Suppose the outcomes are equally likely. Compute the probability of the event E = 'an odd number less than 9."P(E)=(Type an integer or a decimal. Do not round.)

Answers

We have a sample space S = {1, 2, 3, 4, 5, 6, 7, 8 ,9, 10}.

Each outcome of this sample space is equally likely.

We have to compute the probability of the event E = 'an odd number less than 9'.

Then, event E happens when one of this outcomes happens: 1, 3, 5 or 7. That is 4 outcomes out of 10.

As all the outcomes are equally likely, the probability of event E will be the quotient between the number of success outcomes (4) and the number of total outcomes (10):

[tex]P(E)=\frac{4}{10}=0.4[/tex]

Answer: the probability of event E is P(E) = 0.4.
