What is the domain of the function graphed below?
Answer:
The second option
Step-by-step explanation:
Hello!
The domain of a graph is the interval in which the graph is on the x values.
This graph has all the x values that are greater than or equal to -3, as the graph is to the right of it.
The answer would be the second option: [tex]D : x/x \geq -3[/tex]
The range is the y-values of the graph. The y value of this graph is above 0, so it would be y ≥ 0

What is the area of the circle with the equation 2x2 + 2y2 = 8?
show work pls !!
Answer:
4pi
Step-by-step explanation:
Divide through by two to get
x^2 + y^2 = 4 4 = radius squared radius = 2
area = pi r^2 = 4 pi
Answer: 4π
Step-by-step explanation:
Under the assumption that those are exponents, and your equation is:
[tex]2x^2+2y^2=8[/tex]
You first must turn this circle equation into standard form. The standard form for the equation of a circle is as follows:
[tex](x-a)^2+(y-b)^2=r^2[/tex]
For your case, the constants 'a' and 'b' are clearly zero. We have an annoying coefficient of 2 which can be cancelled by dividing both sides by 2:
[tex]x^2+y^2=4[/tex]
If you'd like, we can write this in the following way:
[tex](x-0)^2+(y-0)^2=2^2[/tex]
So, our circle is centered at the origin (0, 0) and has a radius of 2 units. The area of a circle is given by the formula:
[tex]A=\pi r^2[/tex]
[tex]A=\pi (2^2)=4\pi[/tex]
Solve 3x2 = -12x - 15.
Ox= -4 + 2i
Ox=-4+1
Ox=-2 + 2i
Ox= -2
Answer:
x = -2 - i, -2 + i.
Step-by-step explanation:
3x2 = -12x - 15
3x^2 + 12x + 15 = 0
Divide through by 3:
x^2 + 4x + 5 = 0
x^2 + 4x = -5
Completing the square:
x^2 + 4x + 4 = -5 + 4
(x + 2)^2 = -1
x + 2 = √-1 = i
x = -2 - i, -2 + i.

25% of z is 150. Find the value of z.
(Can y’all show your work on this so I know how you got it)
Answer:
z = 600
Step-by-step explanation:
Method 1 - ratios
If 150 is 25% then z is 100%:
[tex]\begin{aligned} 150 : 25 & = z : 100\\\dfrac{150}{25} & = \dfrac{z}{100}\\150 \cdot 100 & = 25z\\15000 & = 25z\\z & = \dfrac{15000}{25}\\z & = 600 \end{aligned}[/tex]
Method 2
Calculate the amount for 1%, then multiply by 100% to find z:
25% = 150
⇒ 1% = 150 ÷ 25 = 6
⇒ z = 100% = 6 x 100 = 600

Find the exact circumference of a circle with a diameter of 5 inches.
The circumference is
inches.
Answer:
15.7 in
Step-by-step explanation:
You can use the below formula to find the circumference of the circle.
C = π × d
Here,
d ⇒ diameter ⇒ 5 in
Let us find it now.
C = π d
C = 3.14 × 5
C = 15.7 in
Answer:
The exact diameter is 15.707963267948966192313216916398 inches multiplied by full form of pi.
________________________________________________________
SolveSet C as your substitute for circumference.
[tex]C =[/tex]
Now that we have this, we need to assign a value of pi long form followed by the diameter, which is 5 inches².
[tex]C = \pi d[/tex]
[tex]d = 5[/tex]
Lastly, ignore C, and multiply pi by the diameter, d.
[tex]\pi * d = 15.707963267948966192313216916398[/tex] without rounding

find the x and y intercepts of the linear equation 2x - 4y = -20
Answer:
see explanation↓
Step-by-step explanation:
We are given the following equation of a line:
[tex]2x-4y=-20[/tex]
To determine the x-intercept we must set "y = 0":
[tex]2x-4(0)=-20[/tex]
[tex]2x=-20[/tex]
Now, we divide both sides by 2:
[tex]x=-\frac{20}{2}=-10[/tex]
Therefore, the "x" intercept is -10.
To determine the y-intercept we set "x = 0":
[tex]2(0)-4y=-20[/tex]
[tex]-4y=-20[/tex]
Now, we divide both sides by -4:
[tex]y=\frac{-20}{-4}=5[/tex]
Therefore the y-intercept is 5.

x² - 7x+10=0
Answer:
x²-7x+10=0
x²-5x-2x+10=0
x(x-5)-2(x-5)=0
(x-2)(x-5)=0 ANS!
Step-by-step explanation:
First we will multiply x² into 10, the answer will be 10x². Now, take L.C.M of 10, the L.C.M will be 5x2 or 2x5. Now we will make sure that:
2x x 5x=10x² while 5x+2x=7x. Now, we know that 7x is in negative so, we will change the signs and it will become x²-5x-2x+10=0. Now take common:
x(x-5)-2(x-5)=0. Now, write the common taken numbers first and then the other brackets in last i.e: (x-2)(x-5)=0

In the triangle shown, the ratio of the height to the length of the base is 3:4.
Chose True or False on A-C.
A. The area of the triangle is twice the area of a parallelogram with the same base and height
B. The height is 3/4 the base length.
C. The area is 8.64 mm²
Answer:
A. False
B. True
C. True
Step-by-step explanation:
A: Area of traingle = 1/2 × Base Length × Height
Area of parallelogram = Base Length × Height
Therefore, Statement A is False.
B: Base on the ratio for height to base length 3:4,
Statement B is True.
C: Base Length = 4.8 ÷ 4 × 3
= 3.6 mm
Area of Triangle = 1/2 × Base Length × Height
= 1/2 × 3.6 × 4.8
= 8.64mm²
Therefore, Statement B is True.

Milk is on sale for 40% off when it is normally $3.75 per gallon. How much will a gallon of milk cost?
The discounted price for milk is $_____(Round to the nearest cent.)
Answer:
$2.25 is the discounted price for each gallon.
Step-by-step explanation:
So you take 40% and convert it into decimal form, which is 0.4. Then you take $3.75 x 0.4 = 1.5. Then subtract $1.50 from $3.75, and that equals $2.25 each gallon.

The hexagon surface area is the amount of space on it
The surface area of the hexagon is 665.11 square centimeters
How to determine the surface area?The question is incomplete, as the diagram is not given.
So, I will calculate the surface area of the hexagon.
The side length of the hexagon is given as:
L = 16 km
The surface area of the hexagon is calculated using:
A = 1.5[tex]\sqrt3[/tex]L^2
This gives
A = 1.5 * [tex]\sqrt3[/tex] * 16^2
Evaluate the product
A = 665.11
Hence, the surface area of the hexagon is 665.11 square centimeters

Find the area of each circle with the given radius or diameter. Use 3.14 for pi.
Answer: (Note*: Radius is half of the diameter, so the d = 2 and d = 12 have been converted into radius's instead to solve the problem).
r^2 = 4 in: 50.24 in^2.
r^2 = 2 in: 12.56 in^2.
d = 2 or r^2 = 1 in: 3.14 in^2.
r^2 = 8 in: 200.96 in^2.
d = 12 or r^2 = 6 in: 113.04 in^2.
Step-by-step explanation: To find the area of a circle, you need the radius squared times pi, which is 3.14. The following is solved below:
4^2 x 3.14 = 50.24 in^2.
2^2 x 3.14 = 12.56 in^2.
1^2 x 3.14 = 3.14 in^2.
8^2 x 3.14 = 200.96 in^2.
6^2 x 3.14 = 113.04 in^2.
Therefore, the following above are the answers you need.
Let me know if this is right! :)
Answer:
r = 4.) 50.24
r = 2.) 12.56
d = 2.) 3.14
r = 8.) 200.96
d = 12.) 113.04
Step-by-step explanation:
The formula for finding the area of a circle would be π(pi) x r (radius)²
1.) r = 4
4 x 4 = 16
16 x 3.14 = 50.24
2.) r = 2
2 x 2 = 4
4 x 3.14 = 12.56
3.) d = 2
2 ÷ 2 = 1
1 x 1 = 1
1 x 3.14 = 3.14
4.) r = 8
8 x 8 = 64
64 x 3.14 = 200.96
5.) d = 12
12 ÷ 2 = 6
6 x 6 = 36
36 x 3.14 = 113.04
