Answer:
The midpoint is (-2.5, -6)
Step-by-step explanation:
To find the x coordinate of the midpoint, average the x coordinates of the endpoints
(0+-5)/2 = -5/2 = -2.5
To find the y coordinate of the midpoint, average the y coordinates of the endpoints
(0+-12)/2 = -12/2 = -6
The midpoint is (-2.5, -6)
Two positive numbers have a difference of 21. The larger number is five more than twice the smaller. Find the two numbers.
Answer:
X = 29
Y = 8
Step-by-step explanation:
X - y = 21
X = 2y + 5
Substitute:
2y+5-y= 21
2y = 16
Y = 8
X-8 = 21
X = 29
A surveyor is using indirect measurement to find the height of a cliff. He is 4 feet tall and is standing 32 feet away. How tall is the cliff?
Answer:
256 ft
Step-by-step explanation:
[tex]\frac{x}{32} =\frac{32}{4}[/tex]cross multiply
4x = 32(32)
4x = 1024
x =256

A city has a population of 340,000 people. Suppose that each year the population grows by 5.25%. What will the population be after 15 years?
Answer:
Future population = 720800
Step-by-step explanation:
Below is the calculation of population after 15 years.
Given the present population = 340000
Growth in population = 5.25%
Use below formula to find the values:
Future population = Present population ( 1 + r)^n
Future population = 340000 ( 1 + 5.25%)^15
Future population = 340000 (2.15)
Future population = 720800

Answer:
Arc AB = 110
Step-by-step explanation:
<C = 55 degrees. That's the way the triangle is marked. AB = BC.
The central angle is twice the angle made by the end points of line AB
The central angle = 2*55 = 110
The measure of arc AB equals the central angle which makes arc AB = 110
Find the measure of x and y
Answer:
y - 41°
x - ?
Step-by-step explanation:
use method of Z equation
Z 41° so y is 41° too
make sense
Macy's buys a coat from the manufacturer for $22.00. They markup the coat by 75%. Ms. Tonyes buys the coat and uses a 15% off coupon. How much does Ms. Tonyes pay for the coat before tax?
Answer:
Toney buys the coat for $ 14.8.
Step-by-step explanation:
Cost of coat =$ 22
Mark up by 75 %
discount = 10 %
Let toney pay $ R for the coat.
So, according to the question
R + 75 % R = 1.75 R
Now the cost is
1.75 R - 15 % of 1.75 R = 22
1.75 R - 0.2625 R = 22
R = 14.8
So, he buy the coat for $ 14.8.

Find a point on the line and the line's slope.
y+4=-3/2(x+7)
Answer:
The slope is 3/2 and a point on the line is (-7,-4)
Step-by-step explanation:
Point slope form of a line is
y -y1 = m(x-x1) where m is the slope and (x1,y1) is a point on the line
y+4=-3/2(x+7)
y - -4 = 3/2 ( x - -7)
The slope is 3/2 and a point on the line is (-7,-4)

What are the coordinates of the hole in the graph of the function?
f (x) = x^2 − 3x − 10
x−5
Enter your answer in the boxes.
Answer:
The hole is at (5,7)
Step-by-step explanation:
x^2 − 3x − 10
-------------------
x−5
Factor the numerator
(x-5)(x+2)
-------------------
x−5
There is a hole at x=5 since it will cancel in the numerator and the denominator
f(x) = x+2 and letting x = 5
f(5) = 5+2
The hole is at (5,7)

find the slope of a line parallel to given line.
Answer:
-3
Step-by-step explanation:
If lines are parallel to each other, they will never touch so the slope will be the same.
So if the first line is already given in slope intercept form, that means the -3 is the slope.
So a line parallel to this would have the slope -3 and start at a different place on the y axis.
Use the Pythagorean theorem to classify the triangle
formed by the three fences. Which is true about the
numbers 5, 12, and 13?
Answer:
they are equal
Step-by-step explanation:
The triangle with sides 5, 12, 13 is a right triangle because
a^2+b^2 = c^2
5^2+12^2 = 13^2
25+144 = 169

Determine the range of the inverse of f(x) = 2x + 1
Answer:
The range is all real numbers for the inverse
Step-by-step explanation:
f(x) = 2x+1
The domain is all real numbers
The range is all real numbers
For the inverse, the domain becomes the range
The range becomes the domain
The domain is all real numbers
The range is all real numbers
Step-by-step explanation:
Given the function f(x) = 2x + 1
find : the range of the inverse of f(x) = 2x + 1
solutions:
f(x) = 2x + 1
y = 2x + 1
2x = y - 1
x = (y -1)/2
f~¹(x) = (x-1) /2
since the denominator is the constant number, so the range of function is all Real numbers

If y=-2x+6 wee changed to y=3x+2 how would the graph of the new line compare with the first one
Answer: (a)
Step-by-step explanation:
Given
The given graph is y=-2x+6 and it changed to y=3x+2
The slope of the graph determines the steepness
Slope changes from -2 to 3. So, latter graph is more steeper.
Also, y intercept is obtained by putting x as 0
Y intercept changes from 6 to 2 i.e. decrease of 4 units
Hence, option (a) is correct.

The LCM of two numbers is 48. The number one in the ratio 2:3. Then Sum of the numbers is:
a) 16
b) 14
c) 32
d)28
Answer:
40
Step-by-step explanation:
Let the numbers be 2x and 3x
Then their L.C.M. = 6x
BUT also their LCM=48
6x=48
x=48/6
x=8
So,
First number=2x=2x8=16
Second number=3x=3x8=24
The numbers are 16 and 24.
Hence required sum =(16+24)=40
So none of the options are correct
