A circle is shown. Secant X Z and tangent W Z intersect at point Z outside of the circle. Secant X Z goes through the center of the circle and intersects the circle at point Y. The length of W Z is k + 4, the length of Z Y is k, and the length of X Y is 12.
What is the length of line segment XZ?
Answers
Given:
Consider the below figure attached with this ques.
To find:
The length of the line segment XZ.
Solution:
According to the tangent-secant theorem, the square of tangent is equal to the product of secant and external segment of secant.
Using tangent-secant theorem, we get
[tex]WZ^2=ZX\times ZY[/tex]
[tex](k+4)^2=(k+12)k[/tex]
[tex]k^2+8k+16=k^2+12k[/tex]
[tex]8k+16=12k[/tex]
Subtract both sides by 8k.
[tex]16=12k-8k[/tex]
[tex]16=4k[/tex]
Divide both sides by 4.
[tex]4=k[/tex]
Now,
[tex]XZ=12+k[/tex]
[tex]XZ=12+4[/tex]
[tex]XZ=16[/tex]
Therefore, the measure of XZ is 16 units.

Answer:
(6, 840) (5, 700) (3, 420) (4, 560)
Step-by-step explanation:
Use the one point that is completely filled out, (6, 840). Divide 840 by 6 and you get 140 so that is the slope. 5x140= what the y intercept will be, 700. 420/140= what the x intercept will be, 3. Now you can see a pattern which helps check your work. They are all decreasing pretty much, not really ordered much but. And finally the last point 4x140=560. Hope that helps! :)

There are about half a million heart attacks deaths in the United States of America each year acording to womensheart.Org about how many heart attack deaths is there each hour ]
Answers
Answer:
57 deaths per hour
Step-by-step explanation:
In one year, we have 365 days.
Now, there are 24 hours in a day.
Thus,
Number of hours in one year = 365 × 24 = 8760 hours
Now, since there are half a million heart attacks deaths occurring in the United States of America each year, it means that;
There are 500000 deaths every 8760 hours.
Therefore, death rate per hour = 500000/8760 ≈ 57 deaths per hour

a. Write a formula for the area A
of a triangle.
b. Solve the formula for b.
c. Use the new formula to find the
base of the triangle.
A = 36 mm2
h = 6 mm
b
Answers
Answer:
A = 1/2 b * h
b = 2A / h
b = 12
Step-by-step explanation:
Remark
The formula starts out as
A = 1/2 * b * h
You want to rearrange it to show b by itself.
Formula
Multiply by 2
2A = b * h
Divide by h
2A/h = b
Part C
b = 2A / h
A = 36 mm^2
h = 6 mm
b = 2*36 / 6
b = 72 / 6
b = 12 mm

An open-topped fish tank has a length of 30 inches, width of 10 1/2 inches, and height of 12 inches. What is the volume of the water in the tank if the tank is 3/4 filled?
A 945 in
B. 1,287 in
C. 2,835 in
D. 3,780 in
Answers
Answer:
2835 inches cubed
Step-by-step explanation: Volume equals all three sides multiplied by each other so 30*12*10.5=3780 in. However because the tank is only 3/4 full you multiply 3780 by 3/4 to get 2835.

Two trains started moving at the same time, train A from Boston to New York, and train B from New York to Boston. The distance between the train stations in New York and Boston is 240 miles. The average speed of train A is 60 mph, which is 3 4 of the average speed of train B.
1. How soon will the trains meet
2. How far from New York will the trains meet?
Answers
Answer:
------
Step-by-step explanation:
1. The average speed of train A = 60 mph,
The average speed of train B = 60 / 3/4 = 80 mph
Time it takes for trains to meet = 240/(60 + 80) = 240/140 = 12/7 hours
2. The trains meet in 12/7 hours, each traveling at their own speed.
S = D/T, D = S*T
Therefore we can say:
12/7(60) = distance train A is from Boston = 720/7 miles
12/7(80) = distance train B is from New York = 960/7 miles
The distance from New York would = 960/7 miles
Suppose you are in a building at 28 feet above ground level and you take an
escalator down to ground level. On the escalator, your distance above ground level
changes by - 2 feet per second. Write a linear function to describe the distance d
that
you are from ground level over time t in seconds.
Answers
The linear equation that represents the distance (d) above ground level after t seconds is d = -2t + 28
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
The standard equation of a linear equation is:
y = mx + b
Where m is the rate of change (slope) while b is the y intercept.
Let d represent the distance that you are from ground level over time t seconds.
Suppose you are in a building at 28 feet above ground level and you take an escalator down to ground level. On the escalator, your distance above ground level changes by - 2 feet per second. Hence:
d = -2t + 28
The linear equation is d = -2t + 28
