PLEASE HELP The domain is {x∈R| x≠−3}, and the range is {y∈R| y≠−5}. The domain is {x∈R| x≠−2}, and the range is {y∈R| y≠−5}. The domain is {x∈R| x≠−5}, and the range is {y∈R| y≠−2}. The domain is all real numbers, and the range is all real numbers as well.
The domain is {x∈R| x≠−2}
The range is {y∈R| y≠−5}
====================================================
Explanation:
Using the function, we can factor the numerator to get
x^2-x-6 = (x-3)(x+2)
Then the (x+2) terms cancel out leaving x-3 only
Therefore, f(x) simplifies to f(x) = x-3.
This produces the straight line graph that is shown. But there's a hole at (-2,-5)
Why is this? It's because plugging x = -2 into the original equation (before you simplify) leads to a division by zero error.
The denominator x+2 becomes -2+2 = 0 and we can't divide by zero.
If we plugged x = -2 into the simplified version of f(x), then we have
f(x) = x-3
f(-2) = -2-3
f(-2) = -5
Showing why the hole is at (-2,-5)
There is no way that x can equal -2, so this is why we kick it out of the domain. Similarly, there's no way to get to y = -5, and this value is kicked out of the range.
The notation x∈R means that x is in the real number set. Saying {x∈R| x≠−2} means x is any real number but -2. The range is a similar story but we kick out -5 instead.

Step-by-step explanation:
The radius of a circle is 3 m. Find its area to the nearest tenth.
Answer:
28.3 square meters.
Step-by-step explanation:
So we know that the radius of the circle is 3 meters. With that, we can figure out the area of the circle.
The area of a circle is given by the formula:
[tex]A=\pi r^2[/tex]
Plug in 3 for r:
[tex]A=\pi (3)^2[/tex]
Square the number:
[tex]A=9\pi[/tex]
Use a calculator. Approximate:
[tex]A\approx28.2743\approx28.3[/tex]
Therefore, the area of the circle is approximately 28.3 square meters.
Answer:
28.3 m²
Step-by-step explanation:
The area of a circle can be found using the following formula.
[tex]a=\pi r^2[/tex]
We know the radius of the circle is 3 meters. We can substitute 3 m in for the variable, r.
[tex]a= \pi (3m)^2[/tex]
Evaluate the exponent.
(3m)² = 3m * 3m= 9 m²
[tex]a= \pi (9 m^2)[/tex]
Multiply pi and 9 meters squared.
9 m² * π = 28.2743339 m²
[tex]a=28.2743339 m^2[/tex]
Round to the nearest tenth. The 7 in the hundredth place tells us to round the 2 in the tenth place to an 3
[tex]a\approx 28.3 m^2[/tex].
The area is approximately 28.3 square meters.

A granola bite contains 27 calories. Most of the calories come from c grams of carbohydrates. The rest come from other ingredients. One gram of carbohydrate contains 4 calories. The equation 4c + 5 = 27 represents the relationship between these quantities. Step 1: Answer the following questions: a. What could the 5 represent in this situation? b. Priya said that neither 8 nor 3 could be the solution to the equation. Explain why she is correct. c. Find the solution to the equation.
Answer:
a. 5 represents the number of calories that come from other ingredients.
b. Neither 8 nor 3 satisfy the given equation, so neither 8 nor 3 can be the solution to the equation.
c. c = 5.5
Step-by-step explanation:
We are given the equation:
[tex]4c + 5 = 27[/tex]
Where [tex]c[/tex] represents the grams of carbohydrates
27 is the total number of calories that are received by the granola bite.
4 is the number of calories from 1 gram of carbohydrates and
5 is the number of calories that are received from other ingredients.
Answer of Part a:
5 is the number of calories that are received from other ingredients.
Part b:
Let us take left hand side (LHS) and put values of c = 8 and 3 one by one.
So, LHS becomes:
4 \times 8 + 5 = 37 [tex]\neq RHS\ i.e.\ 27[/tex]
4 \times 3 + 5 = 17 [tex]\neq RHS\ i.e.\ 27[/tex]
So, Priya is correct that neither 8 or 3 could be solution.
Part c:
[tex]4c + 5 = 27\\\Rightarrow 4c = 22\\\Rightarrow \bold{c = 5.5}[/tex]
So, solution to the equation is: c = 5.5
Pls help It’s due tomorrow question is in the picture
Answer:
C
Step-by-step explanation:
Let's find the area of each of the two circles.
First Circle:
The first circle has a diameter of 10 inches. That means the radius is 5 inches. So, its area is:
[tex]A=\pi r^2\\A=\pi (5)^2\\A=25\pi[/tex]
Second Circle:
The second circle has a diameter twice that of the first. So, the diameter is 20 inches. This means that the radius is 10 inches. Find the area:
[tex]A=\pi r^2\\A=\pi (10)^2\\A=100\pi[/tex]
Now, find the ratio between them by dividing:
[tex]\frac{\text{Smaller}}{\text{Larger}}=\frac{25\pi}{100\pi}[/tex]
Simplify:
[tex]\frac{\text{Smaller}}{\text{Larger}}=\frac{1}{4}[/tex]
1/4 is the same as 1:4
So, our answer is C :)

*MAKE SURE YOU ANSWER CORRECTLY WITH DETAILS, WILL CHOOSE BRAINLIEST * Describe a hemisphere of this picture and explain how it was formed. If given the radius of the globe, how would you find the volume of the hemisphere?
Answer:
Volume of the hemisphere = [tex]\frac{2}{3}\pi r^{3}[/tex]
Step-by-step explanation:
It's a picture of a globe and a globe of the Earth is in the shape of a sphere.
We know equator divides the earth into two equal halves and these equal halves are called as "hemisphere".
Therefore, a line joining the two extreme points of the diameter of the Earth divides the Earth into two hemispheres.
If the radius of the Earth is 'r',
Volume of the hemisphere = [tex]\frac{2}{3}\pi r^{3}[/tex]

The word demographic comes from ancient Greece. Demos means people. Graphic means picture. Based on the video and this information, which thing below is most likely shown on a demographic map? countries, population, continents, or leaders
Answer:
Population
Step-by-step explanation:
If we know the root Demos means people and graphic means picture, let's put the english terms together.
Demo graphic
People graphic
So this is going to be a "People Graphic." So we know that Countries and Continents are ruled out.
Now I just used logic to figure out whether it's population or leaders. A map showing the leaders of something would be useless, but a map showing population is useful. So I assumed that a Demographic map shows population (I also looked it up to check, and yes this is right.)
Hope this helped!
Answer:
population
Step-by-step explanation:
people graphic
related to ppl so population

Erin is pouring cake batter into a pan. The pan she is using is 8 inches wide,
11 inches long, and 7 cm deep. Erin has made 18 cups of cake batter.(1 cup =
14.44 cubic inches, 1 inch = 2.54 cm) What is the maximum volume, in cubic
inches, the cake pan can hold? (volume of a rectangle: volume-length x
width x height)
Answer:
242.52 cubic inches
Step-by-step explanation:
Volume of the cake pan = Length × Width × Height
From the about question, we have the following dimensions for the cake pan
8 inches wide = Width
11 inches long = Length
7 cm deep = Height
We are asked to find the maximum volume in inches. Hence all the dimensions have to be in inches.
Converting Height in cm to inches
From the question,
2.54 cm = 1 inch
7cm = x inch
Cross Multiply
2.54 × x = 7 × 1
x = 7/2.54
x = 2.7559055118 inches
Volume of the cake pan =
8 × 11 × 2.7559055118
= 242.51968504 cubic inches
Approximately, the volume of the cake pan = 242.52 cubic inches
What is the maximum volume, in cubic
inches, the cake pan can hold is 242.52 cubic inches

Examine the graph. Which statements are true about the function represented by the graph? Select all that apply.
The function is negative over the interval (−16,0).
The function is negative over the interval (−5,3).
The function is positive over the interval (3,∞).
The function is positive over the interval (−∞,−5).
The function is positive over the interval (−5,3).
The function is negative over the interval (−∞,−5).
====================================================
Explanation:
The portion below the x axis is when f(x) is negative. This happens on the interval [tex]-5 < x < 3[/tex]. Note how -5 and 3 are the x intercepts or roots. So because f(x) is negative when [tex]-5 < x < 3[/tex] we can say f(x) is negative over the interval (-5, 3). This is interval notation and not ordered pair notation.
----------
The function f(x) is positive in two places. When x < -5 and when x > 3. This is where the purple parabola is above the x axis.
The x < -5 portion converts to the interval notation (−∞,−5)
The x > 3 portion converts to the interval notation (3,∞)
The function is positive over the interval (3,∞) and interval (−∞,−5) while negative over interval (−5,3) so options (B),(C), and (D) will be correct.
How to plot a graph?A graph is a diagram that shows the fluctuation of one variable in relation to one or more other variables.
In order to plot the graph, we need to find out y's values corresponding to x's value
After that, we need to substitute the values of x's and y's into the coordinate geometry.
If we look at the graph
The value of graph is positive after x = 3 and it is positive before x = -5
Let's say the graph is going infinitely in both directions.
Then the function is positive over the interval (3,∞) and interval (−∞,−5).
The function is negative from x = -5 to 3 so it will be negative over that.
Hence "The function is positive over the interval (3,∞) and interval (−∞,−5) while negative over interval (−5,3)".

What is 1 5/8 times 2 2/3
Answer:
Step-by-step explanation:
Convert mixed fraction to improper fraction.
[tex]1\frac{5}{8}*2\frac{2}{3}=\frac{13}{8}*\frac{8}{3}\\\\\\=\frac{13}{3}\\\\\\=4\frac{1}{3}[/tex]
Answer:
4 1/3
Step-by-step explanation:
1 5/8 × 2 2/3
First we turn it into an improper fraction:
1 5/8 × 2 2/3 = 13/8 × 8/3
Now we multiply them across:
13/8 × 8/3 = 104/24
Now we simplify:
104/24 = 13/3
because 3 × 8 = 24 and 13 × 8 = 104
Now we simplify again because we can't leave it as an improper fraction. So we turn it into a mixed fraction:
13/3 = 4 1/3
4 1/3 is answer

Answer: 137
Step-by-step explanation:
The given expression: [tex]7x^2 +8x-7[/tex]
We need to find the value of the expression when x=4.
So we just use the substitution property and substitute the value of x= 4 in the given expression , we get
[tex]7(4)^2+8(4)-7\\\\= 7(16)+32-7\\\\= 112+25\\\\=137[/tex]
Hence, the value of the expression at x=4 is 137.
what is 75% of £60?
Answer:
45
Step-by-step explanation:
75x60=4500
4500/100=45
Answer:
£45
Step-by-step explanation:
Take 75% of 60: [tex]\frac{75}{100}[/tex] × [tex]\frac{60}{1}[/tex] = [tex]\frac{4500}{100}[/tex] To simplify, look at the denominator. There's a 100 in the denominator. And, 100 has two zeros at the end. In the numerator, we have 4500. 4500 has two zeros in the end as well. First, cancel out the two zeros in 100 to make it 1. Then, to make the fraction even, cancel out the two zeros in 4500 to make it 45. It should now look like this: [tex]\frac{45}{1}[/tex]. We know any number over 1 is itself. So, [tex]\frac{45}{1} = 45[/tex]Therefore, 75% of £60 is £45.
Given T (x,y) = (x+5,y+4) and the point P (2,3) what is T (P)
Answer:
(7, 7 )
Step-by-step explanation:
The translation rule
(x, y ) → (x + 5, y + 4 )
Means add 5 to the original x- coordinate and add 4 to the original y- coordinate, thus
(2, 3 ) → (2 + 5, 3 + 4 ) → (7, 7 )

Find the measure of c. A. 10 B. 280 C. 100 D. 140
Answer:
63°
Step-by-step explanation:
a = 27°
b = 180° - (a + 27°)
b = 180° - (27° + 27°)
b = 180° - 54°
b = 126°
By inscribed angle theorem:
c = 1/2 b = 1/2 * 126°
c = 63°

The Shopkeeper sold her goods for Rs. 16,950 allowing 25%discount and then levied on 13% VAT. What was the amount of discount?
Answer:
The amount of discount is Rs.5,000
Step-by-step explanation:
The given parameters are;
The amount the shopkeeper sold her goods = Rs. 16,950
The percentage discount allowed = 25%
The VAT included in the sale = 13%
Therefore, we have;
Sale amount = Discounted price + VAT percentage × Discounted price
Discounted price = (100 - Percentage discount)/100×Display price
Sale amount = The amount the shopkeeper sold her goods = Rs. 16,950
Let the display price = X;
We have;
Discounted price = (100 - 25)/100×X = 0.75·X
Therefore;
Sale amount = 0.75·X+ 13/100 × 0.75·X
Rs. 16,9504 = 0.8475·X
X = Rs. 16,950/0.8475 = Rs.20,000
Therefore, the display price = Rs.20,000
The amount of discount = Percentage discount × Display price
The amount of discount = 25/100 × Rs.20,000 = Rs.5,000
The amount of discount = Rs.5,000.
