Answer:
y = -2x + 1.5
Step-by-step explanation:
line that passes through the given points (-1,3.5),(1,-0.5), (3,-4.5)
slope (m) = (-0.5 - 3.5) / (1 - -1) = -4 / 2 = -2
(y - -4.5) / (x - 3) = -2 ... pass (3,-4.5)
y + 4.5 = -2x +6
y = -2x + 1.5
Are these slopes equal? Explain if they are or if there not.
Answer:
Yes
Step-by-step explanation:
When dividing (or multiplying) two negative numbers, you end up with a positive number. The other slope is already positive. So 4/5=4/5

Write the equation of a circle with endpoints of the diameter at (4, -3) and (-2, 5).
Show your work for credit.
Answer:
(x - 1)² + (y - 1)² = 25Step-by-step explanation:
Find the center, the midpoint of the diameter:
x = (4 - 2)/2 = 1, this is h of the circle equationy = (-3 + 5)/2 = 1, his is k of the circle equationFind the square of the radius by distance formula:
r² = (1 - 4)² + (1 + 3)² = 25Equation of the circle:
(x - h)² + (y - k)² = r²,Substitute the values to get:
(x - 1)² + (y - 1)² = 25Answer:
solution given:
points at (4, -3) and (-2, 5
diameter [d]=
[tex]d = \sqrt{(4 + 2) {}^{2} +( - 3 - 5) {}^{2} } \\ d = 10units \\ radius(r) = 5units [/tex]
centre[h,k]={(4-2)/2,(-3+5)/2}=(1,1)
now equation of a circle
(x-h)²+(y-k)²=r²
(x-1)²+(y-1)²=25 is a required equation
Find the f^-1(x) and it’s domain
Answer:
[tex]f^{-1}(x) = (x + 8)^2[/tex]
[tex]x \ge -8[/tex]
Step-by-step explanation:
Given
[tex]f(x) = \sqrt x - 8[/tex]
Solving (a): [tex]f^{-1}(x)[/tex]
We have:
[tex]f(x) = \sqrt x - 8[/tex]
Express f(x) as y
[tex]y = \sqrt x - 8[/tex]
Swap x and y
[tex]x = \sqrt y - 8[/tex]
Add 8 to [tex]both\ sides[/tex]
[tex]x + 8 = \sqrt y - 8 + 8[/tex]
[tex]x + 8 = \sqrt y[/tex]
Square both sides
[tex](x + 8)^2 = y[/tex]
Rewrite as:
[tex]y = (x + 8)^2[/tex]
Express y as: [tex]f^{-1}(x)[/tex]
[tex]f^{-1}(x) = (x + 8)^2[/tex]
To determine the domain, we have:
The original function is [tex]f(x) = \sqrt x - 8[/tex]
The range of this is: [tex]f(x) \ge -8[/tex]
The [tex]domain[/tex] of the [tex]inverse[/tex] function is the [tex]range[/tex] of the [tex]original[/tex] function.
Hence, the domain is:
[tex]x \ge -8[/tex]

What is the statement of equal chords of a circle?Equal chords of a circle subtend equal angles at the centre. The converse of the theorem is if two chords subtend equal angles at the centre, they are equal.
In the given diagram chord AB and chord CD subtend the equal angles which are 30°. Therefore, AB=CD=2 cm.
Hence, the value of x, that is chord CD is 2 cm.

Answer:
Answer is E but not 100%
Step-by-step explanation:
Answer:
A is correct
E shows an error as the first two values are identical so one cannot be greater than the other.
Step-by-step explanation:
A shows 2.69 is equal to 2.696 which is more than 2.696 which is more than 2.696 which is more than 2.696
As when;
2.696 repeats in bold = 2.696969696 1st greatest
2.696 repeats in bold = 2.696696696 2nd in highest value so 2nd in order.
2.696 repeats in bold = 2.696666666 3rd in highest value so 3rd in order.
2.696 does not repeat = 2.696 so is the least greatest from the list.
Susan was carrying a pitcher that contained 2/3 of a gallon of lemonade to the table for lunch. She slipped and spilled 1/4 of the lemonade in the pitcher. What fraction of a gallon of lemonade did she spill?
Answer:
Susan spilled 1/6 of a gallon of lemonade.
Step-by-step explanation:
Since Susan was carrying a pitcher that contained 2/3 of a gallon of lemonade to the table for lunch, and she slipped and spilled 1/4 of the lemonade in the pitcher, to determine what fraction of a gallon of lemonade did she spill the following calculation must be performed:
2/3 = 0.6666
0.666666 x 1/4 = X
0.166666 = X
0.166666 = 1/6
Therefore, Susan spilled 1/6 of a gallon of lemonade.

Step-by-step explanation:
Given
[tex]X = \sqrt{t} \\t = X^2[/tex] --- Eq (1)
and [tex]Y = 2t -3[/tex] --- Eq (2)
Substituting the value of "t" from Eq (1) into Eq (2), we get -

The Cartesian form of the parametric equation is y = 2x² – 3 and the graph will be a parabola.
What are parametric equations?A parametric equation in mathematics specifies a set of numbers as functions of one or more independent variables known as parameters.
We have parametric functions:
x = √t ⇒ x² = t
y = 2t—3
Plug t = x² in the other equation, we get:
y = 2x² - 3
The graph will be a parabola.
Thus, the Cartesian form of the parametric equation is y = 2x² – 3 and the graph will be a parabola.

4. The volume of a certain room is 2016 cubic ft. If the square footage of the
floor is 144 sq. ft., what will the height of the room be?

Given
[tex]Volume = 2016ft^3[/tex]
[tex]Base\ Area = 144ft^2[/tex]
Required
The height of the room
This is calculated as:
[tex]Volume = Base\ Area * Height[/tex]
Make Height the subject
[tex]Height = \frac{Volume}{Base\ Area}[/tex]
So, we have:
