Step-by-step explanation:
Using Distance Formula
Distance Formula = \(\sqrt{(x2-x1)^2+(y2-y1)^2}\)
D = \(\sqrt{(1-25)^2+(-3+3)^2}\)
D = \(\sqrt{(-24)^2+(0)^2}\)

Answers
Answer:
-x^2 +4x +6
Step-by-step explanation:
f(x)=4x+1
g(x)=x^2-5
(f-g)(x) = 4x+1 - (x^2-5)
Distribute the minus sign
= 4x+1 - x^2 +5

Consider the quadratic function f(x) = x2 – 5x + 12. Which statements are true about the function and its graph? Select three options. The value of f(–10) = 82 The graph of the function is a parabola. The graph of the function opens down. The graph contains the point (20, –8). The graph contains the point (0, 0).
Answers
The true statements are
The value of f(–10) = 82
The graph of the function is a parabola.
The graph contains the point (20, –8).
What is a Parabola:A parabola is a type of conic section that is formed when a plane intersects a cone in such a way that the angle between the plane and the vertical axis of the cone is equal to the angle between the plane and a generator (a straight line passing through the vertex and the base of the cone).
The resulting shape is a symmetrical, U-shaped curve. The standard form of the parabola is a quadratic function.
Here we have
The quadratic function f(x) = x²/5 – 5x + 12
Now check each option as follows
1. The value of f(–10) = 82
To check this find f(-10) as follows
f(-10) =1/5 (-10)²– 5(-10) + 12 = 20 + 50 + 12 = 82
Hence, The value of f(–10) is equal to 82
2. The graph of the function is a parabola.
As we know the standard equation of a parabola is a quadratic function that is in the form of ax² + bx + c
Hence, the quadratic function represents a parabola
3. The graph of the function opens down.
In the given function f(x) = x²– 5x + 12, the coefficient of the x² term is 1. Since the coefficient of x² is positive, the parabola opens upwards.
Hence, The graph of the function opens down is false
4. The graph contains the point (20, –8).
To check this substitute the point in f(x)
=> –8 = 1/5(20)²– 5(20) + 12
=> –8 = 80 – 100 + 12
=> –8 = –8 [ Which is true ]
Hence, The graph contains the point (20, –8).
5. The graph contains the point (0, 0).
=> 0 = (0)²– 5(0) + 12
=> 0 = 12 [ which is not true ]
Hence, The graph doesn't contain the point (0, 0).
Therefore,
The true statements are
The value of f(–10) = 82
The graph of the function is a parabola.
The graph contains the point (20, –8).

Answers
In "9 years" there will be at least 31 million homes with these devices
According to the question,
The equation is:
\(y = 3x+4\)At least 31 million homes,
\(y \geq 31\)then,
→ \(3x+4 \geq 31\)
By subtracting "4" from both sides of the equation,
→ \(3x+4-4 \geq 31-4\)

A straight highway is 100 miles long, and each mile is marked by a milepost numbered from 0 to 100. A rest area is going to be built along the highway exactly 7 miles away from milepost 58. If m is the milepost number of the rest area, which of the following equations represents the possible locations for the rest area?
Answers
Answer:
Step-by-step explanation:
The milepost number of the rest area is 7 miles away from milepost 58, so it can be represented by the equation:
m = 58 + 7
This equation states that the milepost number of the rest area is equal to 58 plus 7, or 65. Therefore, the rest area can be located at milepost 65.

Answers
The area is 108yd2(square yards).
In the given triangle a base
24yd and the corresponding height of 6 yds are given, so to calculate the area we can use:
A=12×b×h
If we substitute the given numbers we get:
A=\(\frac{1}{2}\)×24×18
=12×9
=108
The units of base and height are the same (yards), so the calculated area is in yd2
The area is the quantity that expresses the extent of a region on the plane or on a curved surface. the world of a plane region or plane area refers to the area of a shape or planar lamina, while area refers to the area of an open surface or the boundary of a three-dimensional object. The area is often understood as the amount of material with a given thickness that would be necessary to fashion a model of the shape, or the quantity of paint necessary to cover the surface with a single coat. it's the two-dimensional analog of the length of a curve (a one-dimensional concept) or the volume of a solid (a three-dimensional concept).

If the 4th and 7th terms of a G.P are −1/2 and
− 4, respectively, then find G5 and S6 .
Answers
Answer:
G5 = -1
S6 = -63/16
Step-by-step explanation:
The formula for finding the nth term of a GP is Tn = ar^n-1
a is the first term
r is the common ratio
n is the number of terms
If the 4th term is -1/2
T4 = ar^4-1
T4 = ar³ = -1/2.... 1
If the 7th term is -4
T7 = ar^7-1
T7 = ar^6 = -4.... 2
Divide both equation
ar^6/ar³ = -4/(-1/2)
r³ = -4×-2
r³ = 8
r = 2
Common ratio is 2
Since ar³ = -1/2
a(2)³ = -1/2
8a = -1/2
a = -1/16
The first term is -1/16
Get the fifth term G5
G5 = ar⁴
G5 = (-1/16)(2)⁴
G5 = (-1/16)(16)
G5 = -1
Get the sum of the first six terms S6
S6 = a(r^n-1)/r-1
S6 = -1/16(2^6-1)/2-1
S6 = -1/16(64-1)
S6 = -63/16
Hence the sum of the first six terms is -63/16
Write the series using summation notation. Then find the sum of the series.

Pablo used a total of 5 3/4 gallons of gas while driving his car. Each hour he was driving, he used 5/6 gallons of gas. What was the total number of hours he was driving? Write your ans
Answers
We know that he used 5/6 gallons of gas per hour of driving.
So, the total amount of gas he used is 5/6 * x.
We also know that he used a total of 5 3/4 gallons of gas.
So, we can set up the equation:
5/6 * x = 5 3/4
To solve for x, we can first convert 5 3/4 to an improper fraction:
5 3/4 = 23/4
Then, we can multiply both sides of the equation by the reciprocal of 5/6:
x = (5 3/4) / (5/6)
x = (23/4) / (5/6)
x = (23/4) * (6/5)
x = 27.6/4
x = 6.9
Therefore, Pablo was driving for a total of 6.9 hours.

What is the exponential distribution?The exponential probability distribution, with mean m, is described by the following equation:
\(f(x) = \mu e^{-\mu x}\)
In which \(\mu = \frac{1}{m}\) is the decay parameter.
The mean for this problem is of:
m = 4.2.
Hence the decay parameter is of:
\(\mu = \frac{1}{4.2} = 0.2381\)
The mass function is then given as follows:
\(P(X \leq x) = 1 - e^{-\mu x}\)
Hence:
\(P(X \leq x) = 1 - e^{-0.2381x}\)
The median time is the value of x for which P(X < x) = 0.5, hence:
\(0.5 = 1 - e^{-0.2381x}\)
\(e^{-0.2381x} = 0.5\)
\(\ln{e^{-0.2381x}} = \ln{0.5}\)
-0.2381x = ln(0.5)
x = -ln(0.5)/0.2381
x = 2.91 minutes.
The upper quartile is the value of x for which P(X < x) = 0.75, hence:
\(0.75 = 1 - e^{-0.2381x}\)
\(e^{-0.2381x} = 0.25\)
\(\ln{e^{-0.2381x}} = \ln{0.25}\)
-0.2381x = ln(0.25)
x = -ln(0.25)/0.2381
x = 5.82 minutes.
The upper 10% is the value of x for which P(X < x) = 0.9, hence:
\(0.9 = 1 - e^{-0.2381x}\)
\(e^{-0.2381x} = 0.1\)
\(\ln{e^{-0.2381x}} = \ln{0.1}\)
-0.2381x = ln(0.1)
x = -ln(0.1)/0.2381
x = 9.67 minutes.

Answers
The equation of line for the given data is y = 5x -1.
According to the given question.
We have a data of points for a equaton of line.
As we know that the standard equation of line is y = mx + b.
Where, m is the slope of line and b is the y intercept.
Since, the points which are given in the data must satisfy y = mx + b.
Therefore,
Lets take the points (1, 4) and (2, 9) and substitute it in y = mx + b to find the value of m and b.
At x = 1 and y = 4
4 = m + b ..(i)
And at x = 2 and y = 9
9 = 2m + b ..(ii)
From equation i and ii
m = 5
So, b = -5 + 4 = -1
Hence, the equation of line for the given data is y = 5x -1.
