jacob, stephen, and jermaine are hiking up half dome mountain in Yosemite National Park. Stephen has hiked 5.6 kilometers and is at an elevation of 1,920 m. Jacob has hiked 9.8 kilometers and is at an elevation of 2,395 m. Jermaine is 1/4 of the way between Steven and Jacob. How far has jermaine hiked and what is his elevation?
The distance that Jermaine hiked and his elevation will be 3.85km and 1103.75 m.
How to illustrate the information?From the information, Stephen has hiked 5.6 kilometers and is at an elevation of 1,920 m whole on the other hand, Jacob has hiked 9.8 kilometers and is at an elevation of 2,395 m.
Therefore, since Jermaine is 1/4 of the way between Steven and Jacob. This will be:
= 1/4(5.6 + 9.8)
= 1/4 × 15.4
= 3.85km
The elevation will be:
= 1/4(1920 + 2495)
= 1/4 × 4415
= 1103.75 m
Therefore, the distance that Jermaine hiked and his elevation will be 3.85km and 1103.75 m.

Three students plan to rent a minivan for the weekend and equally share the rental cost. By adding two more people, they can each save $24. How much is the total rent of the car?
Answer:
Step-by-step explanation:
you have three student then they add two more people right then you just need to muptiply 25 times by 5
The total rent of the car is $15.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Given that, three students plan to rent a minivan for the weekend and equally share the rental cost.
Let the total money to rent a minivan be x.
Now, share of each student = x/3
Adding two more people, they can each save $24.
x/3- (x+2)/5 =24
5x-3(x+2) =24
5x-3x-6=24
2x=30
x=$15
Therefore, the total rent of the car is $15.

What is linear equation?A linear equation is an equation of the first degree in any number of variables, that can be written in the form ax + b = 0 or ax + by + c = 0, where a, b, and c are real numbers and x and y are variables. The coefficients may be arbitrary expressions, but they do not contain any of the variables. A linear equation is defined by a straight line in the Cartesian plane.
Given is an equation, y = 5x-10, we need to find an equation, when graphed with the given equation, will form a system that has no solution,
So, we know that,
A system of equations will have no solution, if,
a1x + b1y + c1 = 0
a2x + b2y + c2 = 0
If (a1/a2) = (b1/b2) ≠ (c1/c2), then there will be no solution.
Therefore, the only equation that fulfills this condition is y = 5(x-2)
Hence, the equation when graphed with the given equation, will form a system that has no solution is y = 5(x-2)

Answers: The rational numbers in that list are:

Contains (1, −3) and has the same stretch factor as
f(x) = 3x2.
Vertex has x-coordinate of −1.
The obtained quadratic function has the same stretch factor as the given function and contains the given point is y = 3x² + 6x - 12
What is defined as the quadratic function?A quadratic function is one of the following: f(x) = ax² + bx + c, where a, b, and c are positive integers and an is not equal to zero. A parabola is a curve that represents the graph of a quadratic function.
Because a quadratic function is indeed a parabolic curve, we use the standard parabola equation.
y = a(x - h)² + k
where a = stretch factor,
h = x-coordinate of vertex and
k = y-coordinate of vertex.
The quadratic function incorporates the point (1, -3) and has the vertex x-coordinate at x = -1. h = -1 is the answer.
It also has the stretch factor of f(x) = 3x². So, a = 3.
Thus, y = a(x - h)² + k
y = 3(x - (-1))² + k
y = 3(x + 1)² + k
Now, because the quadratic function proceeds through (1, -3), we have
y = 3(x + 1)² + k
-3 = 3(1 + 1)² + k
-3 = 3(2)² + k
-3 = 3(4) + k
-3 = 12 + k
k = -3 - 12
k = -15
Similarly, find the value for y.
y = 3(x + 1)² + k
y = 3(x + 1)² - 15
y = 3(x² + 2x + 1) - 15
y = 3x² + 6x + 3 - 15
y = 3x² + 6x - 12
Therefore, the equation of the quadratic function that contains the given point and has the same stretch factor as the given function is y = 3x² + 6x - 12.

Find the volume of a right circular cone that has a height of 16.8 in and a base with a
radius of 4.7 in. Round your answer to the nearest tenth of a cubic inch.
Answer:
Volume of right circular cone is 388.43 in³
Step-by-step explanation:
Height of circular cone = 16.8 in
Radius of circular cone = 4.7 in
We need to find Volume of right circular cone
The formula used for calculating volume of a right circular cone is: [tex]Volume=\pi r^2\frac{h}{3}[/tex]
Putting values and finding volume
[tex]Volume=\pi r^2\frac{h}{3}\\Volume=3.14\times (4.7)^2 \times \frac{16.8}{3}\\Volume=3.14\times 22.09 \times 5.6\\Volume= 388.43 \:in^3[/tex]

Given 2xy - 8x + 5y -20
By writing like terms on one side
2xy - 8x + 5y - 20
By taking common terms outside we get
2x ( y - 4) + 5 ( y - 4)
By taking common terms we get
