What is the equation of the circle with: center (5, 7) and point on the circle: (-2, 8)
Answer:
[tex](x-5)^2+(y-7)^2=50[/tex]
Step-by-step explanation:
Hi there!
Equation of a circle: [tex](x-h)^2+(y-k)^2=r^2[/tex] where the circle is centered at [tex](h,k)[/tex] and r is the radius
Plug in the center (5,7)
[tex](x-5)^2+(y-7)^2=r^2[/tex]
Plug in the given point (-2,8) to solve for r²
[tex](-2-5)^2+(8-7)^2=r^2\\(-7)^2+(1)^2=r^2\\49+1=r^2\\50=r^2[/tex]
Therefore, r² is equal to 50. Plug this back into [tex](x-5)^2+(y-7)^2=r^2[/tex]
[tex](x-5)^2+(y-7)^2=50[/tex]
I hope this helps!

Meliah wants to make a gallon of punch. She uses 2 quarts of orange juice, 1 cup of lemon juice, and 2 1/2 pints of pineapple juice. How many cups of water should she add to make 1 gallon?
Answer:
2 cups of water
Step-by-step explanation:
Meliah wants to make a gallon of punch.
Note that
1 gallons = 16 cups
For Orange juice
She uses 2 quarts of orange juice,
1 quart = 4 cups
2 quarts = x
Cross Mulitiply
2 × 4 cups = 8 cups
For lemon juice
1 cup of lemon juice
For pineapple juice
2 1/2 pints of pineapple juice.
1 pint = 2 cups
2 1/2 pints = x
Cross Mulitiply
2 1/2 × 2 cups = 5 cups
Total number of cups
= 8 cups orange juice + 1 cup lemon juice + 5 cups of pineapple juice
= 14 cups
Hence, the number of cups of water she should add to make 1 gallon is calculated as:
16 cups - 14 cups
= 2 cups of water

Caroline weighs 41,390,000 mg which One and her baby sister waste 3415 g what is the total weight in kilograms
Answer:
44.805 kg
Step-by-step explanation:
Step 1
Convert mg to kg
Caroline weighs 41,390,000 mg
1 mg = 0.000001 kg
41,390,000 mg = x
x = 41,390,000 mg × 0.000001 kg
= 41.39 kg
Step 2
Converting her baby sister weight to kg
1000g = 1 kg
3415 g = x
Cross Multiply
1000x = 3415g × 1 kg
x = 3415g × 1 kg/1000
x = 3.415 kg
Therefore, the total weight in kilograms is
41.39 kg + 3.415 kg
= 44.805 kg

When using the quadratic formula to solve 7x2 – 3x + 2 = 0, which number will be squared as part of the formula?
Answer:
The value of b will be squared
Step-by-step explanation:
Recall that the quadratic formula is [tex]x=\frac{-b\pm\sqrt{b^{2}-4ac } }{2a}[/tex]
You will see that the only squared coefficient is b.

Trish had a square garden with side lengths of 8 feet. She expanded her garden to 10 feet by 8 feet. By how many square feet did she expand the area of her garden?
Answer:
[tex]16\:\mathrm{ft^2}[/tex]
Step-by-step explanation:
Trish's initial garden had an area of [tex]8\cdot8=64\:\mathrm{ft^2}[/tex]. After expanding her garden to be 10 feet by 8 feet, the garden has an area of [tex]8\cdot 10=80 \:\mathrm{ft^2}[/tex]. Therefore, the garden was expanded by [tex]80-64=\boxed{16\:\mathrm{ft^2}}[/tex]

Aiden brought chocolate and vanilla cupcakes to school for his birthday. 12 students picked a vanilla cupcake and 88 students picked a chocolate cupcake. What percentage of the students picked a vanilla cupcake?
Answer:
the percentage is 12%
Step-by-step explanation:
Given that
The 12 students picked up the vanilla cupcake
And, 88 students picked up the chocolate cupcake
We need to find out the percentage of the students picked up a vanilla cupcake
So, the percenatge is
= (12) ÷ (12 + 88) × 100
= 12 ÷ 100 × 100
= 12%
Hence, the percentage is 12%

The three numbers are in the ratio 4:5:6 . If the sum of the largest and
the smallest number is equal to the sum of second largest number
and 55. Find the numbers. pls answer the question fast I don't have time
Answer:
Step-by-step explanation:
Let the 3 numbers be 4x , 5x and 6x
4x + 6x = 5x + 55
10x = 5x + 55 Subtract 5x from both sides.
5x 5x
5x = 55 Divide by 5
x = 55/5
x = 11
Therefore the numbers are
3*11 = 33
4*11 = 44
5*11 = 55
What is the area of triangle ABC?
9514 1404 393
Answer:
C. 36√3 square units
Step-by-step explanation:
Your knowledge of special triangles tells you that height CD is ...
CD = 6√3
so the area is ...
A = 1/2bh
A = 1/2(12)(6√3) = 36√3 . . . . square units

Additional comment
The 30°-60°-90° right triangle that is half an equilateral triangle has a short side equal to half the length of the long side. The Pythagorean theorem tells you that the middle-length side is √(2²-1²) = √3 times the shortest side. That is, the side length ratios in this "special" triangle are ...
1 : √3 : 2
This means the length DB is 12/2 = 6, and the length CD is 6√3.
El corredor belga Stefaan Engels tenía el record de correr 365 maratones seguidos. Pero ese record se lo ha arrebatado Ricardo Abad, que con 41 años ha entrado en el libro Guiness, como el que ha corrido durante mas veces seguidas la distancia de 42,195 metros, un total de 500 maratones. ¿En cuántos metros en total corridos estaba el record de Stefaan Engels antes de que Ricardo Abad lo superase?
Answer:
15401.175 metros
Step-by-step explanation:
El corredor Belga tenía 365 maratones que a razón de 42.195 metros son:
365 * 42.195 = 15401.175 metros
Find an equation of the circle that has center (-2, 6) and passes through (-6, 1).
Answer:
(x+2)^2 + (y-6)^2 = 41
Step-by-step explanation:
The equation for a circle is (x-h)^2+(y-k)^2=r^2
So first, it is known that the circle's center is at (-2,6), Therefore, this can be filled in:
(x+2)^2+(y-6)^2=r^2
Next, we need to find the radius, and one of the points is already known, being (-6, 1)
With this, find the distance between these two points by doing the Pythagorean Theorem, a^2+b^2=c^2. The a^2 would be the x value changed and the b^2 would be the y value changed between the two numbers. Note that this is interchangeable.
To find a:
-2 to -6 = change of 4
To find b:
6 to 1 = change of 5
Next, write out the equation for this:
4^2+5^2=c^2
16+25=c^2
41=c^2
c = √41
The radius would be √41, so the equation can now be completed. Since c will be brought to the second power, this will cancel out the square root.
(x+2)^2 + (y-6)^2 = 41
Hope that helps.
