Answer: The missing coordinate R is 5.
Step-by-step explanation:
11=1/2(-4) + B
11=-2 +B
B= 13
B represents the y-intercept
so we will use the equation y=mx + B and we know the slope and y intercept.
r= 1/2(-16) + 13
r= 5

What is the sum of 1-2 and V-18?
Answer:
v-19
Step-by-step explanation:
Answer:
It depends on what you mean.
Step-by-step explanation:
If its to separate questions,
1-2= 1
V-18= -13
If its one whole question then
1-2 - V-18= 14
1-2 / V-18= -0.07692307692
1-2 * V-18= -13
1-2 + V-18= -12

José represents the linear function f(x) = 5x – 7 with words.
Multiply each element in the domain by negative 7 and add 5.
Correct his error.
Answer:
-2
Step-by-step explanation:
The correct statement that Jose is supposed to have written is that multiply each element in the domain by 5 and subtract 7
Given the linear function written by Jose expressed as f(x) = 5x - 7
Note that the expression is in form of a linear equation y = mx + b where:
x is the input value known as the domain
We are to write the function f(x) = 5x - 7 in words.
Let the domain variable be x
5x means that we are to multiply each element in the domain 5
For 5x - 7, we are to multiply each element in the domain by 5 and subtract 7.
The correct statement that Jose is supposed to have written is that multiply each element in the domain by 5 and subtract 7

Step-by-step explanation:
To find Hypotenuse: Pythagorean Theroem
a^2+ b^2= c^2
The legs are A and B
The side that is directly across from the Right angle is C
12^2 + 16^2 =C^2

400 = c^2
Square root on both sides to get rid of c^2
The square root of 400 is 20
c=20

140
Answer: 140 m3
Step-by-step explanation:
Multiply the area of the trapezoid face by the length .
Since the area is 20, you multiply it by 7 to get 140
Answer:
140 m^3
Step-by-step explanation:
This is a prism with a trapezoid base.
The volume if a prism is
V = (area of base) * height
The base is the trapezoid in the front face. The height is the distance between bases which is 7 m.
area of trapezoid = (b1 + b2)h/2
In the area of the trapezoid, h is the height of the trapezoid which is the distance between parallel bases. It is 4 m in this case.
V = (area of base) * (height of trapezoid)
V = (8 m + 2 m)(4 m)/2 * 7 m
V = 20 m^2 * 7 m^2
V = 140 m^3

13. A circle with radius x is shown below. The diagram is not drawn to scale. (1 point)
What is the value of x? Round the answer to the nearest tenth.
Answer: 16.1
Step-by-step explanation:
x^2 = 8^2 + (28/2)^2
x^2=64 + 196
x^2= 260
Take the square root of 260 and get 16.1!
The value of x is x=16.1
Chord
The perpendicular from the center of a circle bisects the chord
RadiusA line from the center of the circle to the circumference of the circle is the radius of the circle
Lets connect the center of the circle to the other end of the chord that is at the circumference of circle
The diagram attached below
The line OA from the center bisects the chord
AB= half of 28 = 14
the triangle AOB forms a right angle triangle
apply Pythagorean theorem to find out the value of x
[tex]x^2=8^2+14^2\\x^2= 64+196\\x^2=260\\\sqrt{x^2}=\sqrt{260} \\ x=16.1[/tex]

Answer:
1. Z = 1.75
2. False Positive
Step-by-step explanation:
1. mean = 1750 calories
standard deviation, sd = 200 calories
value of interest, x = 2,100
z-score is computed as follows:
Z = (x - mean)/sd
Z = (2100 - 1750)/200
Z = 1.75

What is the true solution to 2 In x=2 in 8
Answer:
x=2 is the true solution.
Step-by-step explanation:
We have been given the expression:
2\ln 4x=2\ln 8
Using:
n\ln m=\ln m^n
Our given expression becomes:
\ln{4x}^2=\ln{8^2}
Cancel ln from both sides we get:
4x^2=8^2
On simplification we get:
16x^2=64
x^2=4
Final simplification gives the result:
x=2
Answer:
x = 8
Step-by-step explanation:
2 In x=2 ln 8
Divide by 2
ln x = ln 8
Raise to the e base
e^ ln x = e^ ln 8
x = 8
Find an explicit formula for the geometric sequence 3, 15, 75, 375...
Answer:
3 * 5 ^ (n-1)
Step-by-step explanation:
3 is the first term and it multiplies by 5
The explicit formula for the geometric sequence is [tex]T_n = 3(5)^{n-1}[/tex]
The standard explicit formula for a geometric sequence is expressed as:
[tex]T_n = ar^{n-1}\\[/tex]
a is the first term
r is the common ratio
n is the number of terms
Given the sequence of numbers 3, 15, 75, 375...
r = 15/3 = 75/15 = 5
a = 3
Substitute the given parameters into the formula to have:
[tex]T_n = ar^{n-1}\\T_n=3(5)^{n-1}[/tex]
Hence the explicit formula for the geometric sequence is [tex]T_n = 3(5)^{n-1}[/tex]

Maria bought an SUV for 21,000 dollars. Nancy bought a sedan for 2/3 as much. How much less did Nancy spend on her sedan?
Answer:
7000
Step-by-step explanation:
21,000*(2/3)=14000
21,000-14,000=7000
Answer:
7,000 dollars
Step-by-step explanation:
21,000 divided by 3 is 7,000 = 1/3
So 2/3 = 7,000 x 2 = 14,000
To find how much less Nancy spent on her sedan you do 21,000 - 14,000 = 7,000
