Answer:
Step-by-step explanation:
The standard form of a circle is
[tex](x-h)^2+(y-k)^2=r^2[/tex] where h and k are the center of the circle and r is the radius. Our center is located at (0, 1), so h = 0 and k = 1. Going from the center straight up of down we have to move 2 units to get to a point on the outside of the circle, so r = 2. Filling in our equation:
[tex](x-0)^2+(y-1)^2=2^2[/tex] which simplifies a bit to
[tex]x^2+(y-1)^2=4[/tex]

9*__=33?
Answer:
11/3
Step-by-step explanation:
Step 1:
Start by setting it up with the divisor 33 on the left side and the dividend 9 on the right side like this:
3 3 ⟌ 9
Step 2:
The divisor (33) goes into the first digit of the dividend (9), 0 time(s). Therefore, put 0 on top:
0
3 3 ⟌ 9
Step 3:
Multiply the divisor by the result in the previous step (33 x 0 = 0) and write that answer below the dividend.
0
3 3 ⟌ 9
0
Step 4:
Subtract the result in the previous step from the first digit of the dividend (9 - 0 = 9) and write the answer below.
0
3 3 ⟌ 9
- 0
9
You are done.
The answer is the top number and the remainder is the bottom number.
Therefore, the answer to 9 divided by 33 calculated using Long Division is:
0
9 Remainder

PLEASE HELP (look at the photo) I will mark brainleist!
Answer:
I believe its c $1520 overall there's only a decrease of 5%
Answer:
The value of the investment on August 1st is $1,512.
Step-by-step explanation:
To find the value of the percentage decreased by the percent of its value, simply subtract a number to a percent. To find the value of the percentage increased by the percent of its value, add a number to the percent. In this case, the value of the investment started with $1,600 and then it decreased by 10%. We can write our equation like this: 1,600 - 10% = ?. Don't think about turning 10% into 0.1. You could do that, but it wouldn't result in the answer as the value decreased by 10%. It would turn out to be 1,599.9 if you did subtract 1,600 by 0.1. It is NOT the value DECREASED by 10%. I think some people would mistakenly go on to that path but please don't. You will NOT recieve an accurate answer. Following the equation, you should get $1,440. That is the investment made during the month of June decreased by 10%.
During the month of July, the value INCREASED by 5%. Similar to the percentage decreased equation, we just turn the subtraction symbol into an addition symbol. Do the same process again but with an addition symbol and the NOW value of $1,440. You should get $1,512 as your final answer. If you are confused about how I got this answer, look at this equation for percentage increased: 1,440 + 5% = ?. If I am wrong, please let me know and I hope this helps! :D

y-6=4(x+5) what is y and x intercept?
Answer:
x = [tex](-\frac{13}{2} ,0)[/tex] y = (0,26)
Step-by-step explanation:
First find the x intercept
To find the x intercept, substitute 0 for y and solve for x.
[tex](0)-6=4(x+5)[/tex]
Rewrite the equation as [tex]4(x+5)=(0)-6[/tex]
[tex]4(x+5)=(0)-6[/tex]
Subtract 6 from 0.
[tex]4(x+5)=-6[/tex]
Divide each term in [tex]4(x+5)=-6[/tex] by 4.
[tex]\frac{4(x+5)}{4} =\frac{-6}{4}[/tex]
Cancel the common factor of 4.
[tex]x+5=\frac{-6}{4}[/tex]
Simplify [tex]\frac{-6}{4}[/tex]
[tex]x+5=-\frac{3}{2}[/tex]
Subtract 5 from both sides of the equation.
[tex]x=-\frac{3}{2} -5[/tex]
To write [tex]-5[/tex] as a fraction with a common denominator, multiply by [tex]\frac{2}{2}[/tex]
[tex]x=-\frac{3}{2}-5[/tex] · [tex]\frac{2}{2}[/tex]
Combine [tex]-5[/tex] and [tex]\frac{2}{2}[/tex].
[tex]x=-\frac{3}{2} +\frac{-5*2}{2}[/tex]
Combine the numerators over the common denominator.
[tex]x=\frac{-3-5*2}{2}[/tex]
Simplify the numerator.
[tex]x=\frac{-13}{2}[/tex]
Move the negative in front of the fraction.
[tex]x=-\frac{13}{2}[/tex]
x = [tex](-\frac{13}{2} ,0)[/tex]
-----------------------------------------------------------------------------------------------------
Find the y-intercepts.
To find the y-intercept(s), substitute in 0 for x and solve for y.
[tex]y-6=4((0)+5)[/tex]
Add 0 and 5.
[tex]y-6=4 *5[/tex]
Multiply 4 by 5.
[tex]y-6=20[/tex]
Add 6 to both sides of the equation.
[tex]y=20+6[/tex]
Add 20 and 6.
[tex]y=26[/tex]
y = (0, 26)

Answer:
Choice A
Step-by-step explanation:
A = 1/2 (b1+b2)h
Multiply each side by 2
2A = (b1+b2)h
Divide each side by (b1+b2)
2A/ ((b1+b2) = h
Answer:
A
Step-by-step explanation:
We have to isolate h on one side.
First, we remove the 1/2 multiplying by H by multiplying both sides by 2
Which results with:
2A = h(b1+b2)
next we have to get rid of (b1+b2) by
dividing both sides by (b1+b2)
2A/(b1+b2)=h

Compute the electrical consumption of Falogme Family if the present reading in their eletric meter is 5623kwh and the previous reading is 5512kwh
a.110kwh
b.111kwh
c.112kwh
d.121kwh
Answer:
1) c. Use only appliances to do the most important task in the house.
2) b. 112kwh
3) b. 111kwh
Step-by-step explanation:
Energy can be defined as the ability (capacity) to do work and it's measured in Joules. The various forms of energy are solar energy, chemical energy, thermal energy, wind energy, nuclear energy, electrical energy, etc.
Power can be defined as the energy required to do work per unit time.
Mathematically, it is given by the formula;
[tex] Power = \frac {Energy}{time} [/tex]
Energy consumption is the total amount of power used by an electronic device per unit time and it's measured in Watt-hour or Kilowatt-hour.
Mathematically, it is given by the formula;
[tex] Energy = power * time [/tex]
Generally, the most economic way to lessen electric consumption is by ensuring only the important electrical appliances are used at all times.
2. Given the following data;
Previous reading = 2156 KWh
Present reading = 2268 KWh
To find how many kilowatt-hour was consumed;
Energy consumption = present reading - previous reading
Energy consumption = 2268 - 2156
Energy consumption = 112 KWh
3. Given the following data;
Previous reading = 5512 KWh
Present reading = 5623 KWh
To find the electrical consumption of Falogme Family;
Electrical consumption = present reading - previous reading
Electrical consumption = 5623 - 5512
Electrical consumption = 111 KWh

An animal shelter provides shelter for dogs and cats. The animal shelter currently has a total of 117 animals. If the number of cats is 3 more than 5 times the number of dogs, how many dogs and cats are currently at the animal shelter?
Answer:
98 cats and 19 dogs
Step-by-step explanation:
cat = c
dog = d
The animal shelter currently has a total of 117 animals
c + d = 117
c = 117 - d
the number of cats is 3 more than 5 times the number of dogs
c = 3 + 5d
subtitute c
117 - d = 3 + 5d
117 - 3 = 5d + d
114 = 6d
6d = 114
d = 114/6 = 19
so, the cat is 117-19 = 98

find the perimeter of the trapezoid
Answer:
Perimeter you add up all the sides. If it is a horizontal or vertical line, you just write those values for the side lengths. For the slanted one, I would use pythagorean theorem to solve it.
Step-by-step explanation:
If we make a right triangle using vertical and horizontal lines. We will find that a = 6, and b = 12. Find the square root of the sum of a squared plus b squared. That will tell you C. Then add C to the other 3 sides and that will give you the perimeter.
Write an equation of the line in point slope form given the information below slope= 7 point (1,4)
Answer:
y-4=7(x-1)
Step-by-step explanation:
y-y1=m(x-x1)
y-4=7(x-1)
The equation of the line with a slope of 7, passing through the point (1,4), in point-slope form is y = 7x - 3.
To write the equation of a line in point-slope form, we use the formula:
y - y₁ = m(x - x₁)
where m represents the slope of the line and (x₁, y₁) represents the coordinates of a point on the line.
In this case, the given slope is 7 and the point (1,4) lies on the line. Plugging in the values into the formula, we have:
y - 4 = 7(x - 1)
Simplifying the equation, we can distribute the 7:
y - 4 = 7x - 7
To isolate y, we can add 4 to both sides of the equation:
y = 7x - 7 + 4
y = 7x - 3

Answer:
<H = 40
Step-by-step explanation:
Complementary angles add to 90 degrees
2x+10 + x+20 = 90
Combine like terms
3x+30 = 90
Subtract 30
3x+30 -30 = 90-30
3x = 60

3x/3 = 60/3
x = 20
<H = x+20 = 20+20 = 40
What is the image of the point(2,-5) after a rotation of 90 degree counterclockwise about the origin
Answer:
(-2,5)
Step-by-step explanation:
When a point is rotated counterclockwise 90 degrees about the origin then the coordinates of the image will be (x,y) → (-y,x).
Here, (5,2)→(-2,5)
Therefore , if (5,2) is rotated counterclockwise 90 degrees about the origin its image will be point (-2,5).
Hence, if (5,2) is rotated counterclockwise 90 degrees about the origin its image will be point (-2,5).

A map has a scale of 1:200000 How far is it from Belfast to Larne in Km if the distance on the map is 7.8cm
Answer:
15.6km
Step-by-step explanation:
Given the map scale 1:200000
1cm on the map represents 200000 cm on ground or in actual distance
Hence, if distance from Belfast to Larne is 7.8vm on map ;
Actual distance will be :
7.8 * 200000 = 1560000 cm
Converting to km :
Recall :
1000 m = 1km
100 cm = 1 m
Hence,
100000 cm = 1km
Therefore, (1560000 / 100000) km
= 15.6km
Hence, distance between Belfast and Larne is 15.6km
