Which value of x makes the equation 0.1x - 2.5 = 1.0 true
A 10
B 15
C 20
D 35
Answer:
D 35
Step-by-step explanation:
When figuring this out you can just plug in your answers if you want to take it the easier way by just putting in the 35 in places of x and multiplying 0.1 times 35 gets you 3.5 so 3.5 minus 2.5 is 1

the area of the triangle formed by points of intersection of parabola y=a(x-3)(x+2) with the coordinate axes is 10. find a if it is known that parabola opens upward
Answer
1/4 × 6 × (5a) = 12
15a=12
a= 4/5
Step-by-step explanation:
The area of the triangle formed by points of intersection of parabola y=a(x-3)(x+2) with the coordinate axes is 10. The constant (a) of the function is 4.
How to find the if the parabola is open?The triangle formed by the parabola has a base equal to the distance between the points where the graph touches the x-axis and height (h) is the point where the graph touches the y-axis.
The points on the x-axis are the roots of the quadratic equation:
a(x-3)(x+2)=0
(x-3)(x+2)=0
x - 3 = 0
x = 3
or
x + 2 = 0
x = -2
So, the base is the distance between (-2,0) and (3,0).
Since they are in the same coordinate, the distance here;
b = 3 - (-2)
b = 5
The area of the triangle is 10. So
5a = 10 x 2
a = 4
The constant (a) of the function y = a(x-3)(x+2) is 4.

A) −9x − 12y = −72
B) 3x + 4y = 12
C) −3x − 4y = −24
D) 3x + 4y = 24
Answer:
c
Step-by-step explanation:
Answer:
Step-by-step explanation:
use either substitution, elimination, or smthn else.
you need to solve each equation by taking 3x + 4y = 24 with each of the following equations and seeing which equation along with 3x + 4y = 24 gives you no solution/an untrue statement.
Which of these is the standard form of the following function?
f(x) = -9(x + 5)2 + 4
f(x) = 9x2 − 90x − 221
f(x) = -9x2 − 90x − 221
f(x) = 9x2 − 180x + 221
f(x) = -9x2 − 180x − 221

liters of gas does Paul need to fill his gas tank?
no
Answer:
71.915
Step-by-step explanation:
3.785= how many liters that are in a gallon X 19= gallons of gas needed to fill the tank
The number of liters in 1 gallon is 3.78541 therefore,71.92 liters Paul needs to fill in his tank.
What is unit conversion?To convert any unit into another is called a unit conversion.
In order to convert units, we need to care about their dimensions their dimension should not be changed.
Given that,
The amount of fuel Paul's car holds = 19 gallons.
We know that,
1 gallon = 3.78541 liter
Multiply both sides by 19
19 gallon = 71.92 liter.
Hence "The number of liters in 1 gallon is 3.78541 therefore,71.92 liters Paul needs to fill in his tank".

Taylor charges $15 for the first hour of dog walking and $10 for each additional hour or fraction of an hour. The rates that Lucy charges for x hours of dog walking are modeled with the function shown.
f(x) = LaTeX: \lbrace{LaTeX: \begin{matrix}\text{20x, 0 ≤ x ≤ 2}\\\text{10x, 2 4}\end{matrix}20x, 0 ≤ x ≤ 2 10x, 2 4
Who will charge more to walk a dog for 2.5 hours, Taylor or Lucy? How much more?
Who?:
How much more?:
Answer:
Taylor will charge more by $15
Step-by-step explanation:
Given
Taylor
First Hour = $15
Hourly Rate = $10
Lucy:
[tex]f(x) = \left \{ {{20x,\ 0 \le \ x \ \le 2} \atop {10x, x>2}} \right.[/tex]
For a dog walk of 2.5 hours.
Taylor's charges is:
[tex]Charges = First\ Hour + Hourly\ Rate * 2.5[/tex]
[tex]Charges = \$15 + \$10 * 2.5[/tex]
[tex]Charges = \$15 + \$25[/tex]
[tex]Charges = \$40[/tex]
Lucy's charges is:
Here, we consider
[tex]f(x) = 10x[/tex] Because [tex]x > 2[/tex]
i.e 2.5 > 2
So, Lucy's charges is:
[tex]Charges = 10 * \$2.5[/tex]
[tex]Charges = \$25[/tex]
By comparison;
Taylor will charge more by $15
The difference is calculated by:
[tex]Difference = \$40 - \$25[/tex]
[tex]Difference = \$15[/tex]
Decide whether or not the relation is a function.
[(0,1), (-5,4), (0,2), (5,-4)]
Answer:
The relation {(0,1), (-5,4), (0,2), (5,-4)} does NOT represent the relation.
Step-by-step explanation:
We know that a function is a relation where each input or x-value of the X set has a unique y-value or output of the Y set.
In other words, we can not have duplicated inputs as there should be only 1 output for each input.
Given the relation
{(0,1), (-5,4), (0,2), (5,-4)}
From the given relation is clear that the input value x = 0 is repeated twice.
In other words, the input value x = 0 is duplicated.
As we have already mentioned that we can not have duplicated inputs as there should be only 1 output for each input.
Therefore, the relation {(0,1), (-5,4), (0,2), (5,-4)} does NOT represent the relation.

Answer:
The ordered pair to represent the second term as an ordered pair is:
(2, 9)Step-by-step explanation:
Background knowledge about the sequence function
A sequence is defined as the function whose domain is the set of natural numbers (counting numbers).
1, 2, 3, 4, .... n, ....
↓
a₁, a₂, a₃, a₄, .... aₙ, ....
Here,
1 gets mapped onto a₁,
2 gets mapped onto a₂, and so on
The numbers a₁, a₂, a₃, a₄, .... aₙ, .... are the terms of the sequence.
The number aₙ is the nth term of a sequence.
And the sequence function is denoted by {aₙ}.
Given the sequence
3, 9, 15, 21, ...
Here,
a₁ = 3 is the first term
a₂ = 9 is the second term
Thus, the ordered pair to represent the second term as an ordered pair is:

I used the Desmos Polar graph and got the correct answer!!!
A point C reflected about polar-axis has coordinates [tex](5,-\frac{7\pi}{6} )[/tex]
What is polar coordinate system?"It is a two-dimensional coordinate system in which points are given by an angle and a distance from a central point. ""A point are given as [tex](r,\theta)[/tex], where r is the distance of the point from the pole, and [tex]\theta[/tex] is the measure of the angle."For given question,
We have been given four points.
[tex]A=(5,\frac{\pi}{6} ), B=(5,\frac{5\pi}{6} ),C=(5,\frac{7\pi}{6} ),D=(5,\frac{11\pi}{6} )[/tex]
If we plot the above points on the polar coordinate plane then it would be as shown below.
We need to find the point having coordinates [tex](5,-\frac{7\pi}{6} )[/tex]
If we reflect a point [tex]C(5,\frac{7\pi}{6} )[/tex] about polar-axis then the coordinates of the reflected point would be [tex](5,-\frac{7\pi}{6} )[/tex]
Therefore, point C reflected about polar-axis has coordinates [tex](5,-\frac{7\pi}{6} )[/tex]
