what is an equation of a circle with center (-10,6) and radius 8?
Answer:
(x+10) ^2 + (y-6)^2 = 64
Step-by-step explanation:
The equation of a circle can be written as
(x-h) ^2 + (y-k)^2 = r^2 where( (h,k) is the center and r is the radius
(x- -10) ^2 + (y-6)^2 = 8^2
(x+10) ^2 + (y-6)^2 = 64

Answer:
SA = 680 units^2
V =1200 unit^3
Step-by-step explanation:
If the radius is 5 then the diameter is 2r = 2*5 = 10
The height would remain the same
Surface area of a prism is given by
SA = 2 (lw+lh+hw)
l =d = 10 w = d = 10 h = 12
SA = 2 ( 10*10 + 10 * 12+ 12* 10)
SA = 2( 100+120+120)
SA = 2(340)
SA = 680 units^2
V = l*w*h = 10*10*12 =1200 unit^3

What is the inverse of the function? f(x)=3x−1
Answer:
The inverse is 1/3 (x+1)
Step-by-step explanation:
y = 3x-1
Exchange x and y
x = 3y-1
Solve for y
Add 1 to each side
x+1 = 3y-1+1
x+1 = 3y
Divide each side by 3
(x+1)/3 = 3y/3
1/3(x+1) =y
The inverse is 1/3 (x+1)

Find attached to this answer a hand drawn sketch diagram of the Aquarium (rectangular prism) showing its dimensions.
Complete Question
The aquarium shown is a rectangular prism that is filled with water. You drop a spherical ball with a diameter of 8 inches into the aquarium. The ball sinks, causing the water to spill from the tank. How much water is left in the tank? Enter your answer to the nearest tenth. (Hint: 1 in³ = 0.00433 gal)
The dimensions of the rectangular prism is given as:
Height = 13 in
Width = 13 in
Length= 20in
The amount of water left is about ____ gallons.
Answer:
The amount of water left in the tank approximately to the nearest tenth is 13.5 gallons (gal) of water
Step-by-step explanation:
Step 1
We are given a rectangular prism with the dimensions :
Height = 13 in
Width = 13 in
Length= 20 in
The first step would be to find the Volume of the Rectangular prism
Volume of the rectangular prism = Length × Width × Height
= 20in × 13in × 13in
= 3380 in³
From the question, we are given the hint that
1 in³ = 0.00433 gal
This means that 1 in³ of an object contains 0.00433 gallons of water.
Therefore, if
1 in³ = 0.00433 gal
3380 in³ =
Cross multiply
2880 in³ × 0.00433 gal
= 14.6354 gal
This means the Aquarium (rectangular prism) contains 14.6354 gallons of water.
Step 2
A spherical ball with the diameter of 8 inches was dropped into the aquarium.
We would find the volume of the spherical ball.
Volume of the Spherical ball = 4/3πr³
Radius = Diameter ÷ 2
= 8 inches ÷ 2 = 4 inches.
Volume of the Spherical ball = 4/3 × π × 4³
Volume of the Spherical ball = 268.08in³
Step 3
We would be converting the Volume of spherical ball to gallons because this gives us the quantity of water spilled due to the sinking of the spherical ball
If , 1 in³ = 0.00433 gal
268.08in³ =
Cross multiply
268.08 in³ × 0.00433 gal
= 1.1607864 gal.
Step 4
The fourth and final step is to subtract the volume of water in the aquarium from the volume of water spilled
14.6354 gal - 1.1607864 gal
= 13.4746136 gal
Approximately to the nearest tenth = 13.5 gal
Therefore, the amount of water left in the tank approximately to the nearest tenth is 13.5 gallons (gal) of water.

Round 66.3899872389 to the nearest thousandth
Answer:
66.390
Step-by-step explanation:
Answer:
66.39
Step-by-step explanation:
The thousandth place is 0.00. To round, look at the number right after it. If the number is 4 or less, the number stays the same. If the number is 5 or greater, the number is rounded up.
For 66.3899872389, the bold number is the number we are trying to round. The number after it is 9. This number is greater than 5 so you have to round up.
Your answer is 66.39.
Find the surface area AND the volume of the triangular prism
Answer:
SA=1200 in squared. V=2160 in cubed.
Step-by-step explanation:
Let's start with the surface area. The area of of a triangle is 1/2 x b x h. But we have 2 congruent triangle on the prism, so we have this.
2 x 1/2 x b x h.
The 2 and 1/2 cancel so we are left with b x h.
The other sides are easy.
Find the area of the sides we know that have base times height.
16 x 30 + 16 x 9 + 30 x 9...
To find the last side, we need to find the hypotenuse.
To find it, we use the pythagorean theorem.
a²+b²=c²
Use the values of the right triangle's dimensions and plug them in.
16²+30²=c²
256+900=c²
c²=1156
c=34
now using this, we have
16 x 30 + 16 x 9 + 30 x 9 + 9 x 34.
Now solve!
SA = 1200 in squared
The volume is easy.
All we need is the area of the triangular side and multiply it by the depth, 9.
16 x 30 x 1/2 =
240
240 x 9=
2160. in cubed

Answer:
(b) 1/3
Step-by-step explanation:
because it has 3 equal parts
Answer:
As shown in the picture, if the three angles at 0 are equal, the amount of fruits in 3 sections would be equal, too.
It means the total amount of fruits would be divided equally into 3 potions, 1 portion is pawpaw, 1 portion is mango, and 1 portion is orange.

Chris buys 8 more Ninja Turtles than Star Wars action figures. The Ninja Turtles cost $7 each and the Star Wars cost $9 each. Write an expression to model this situation, using S for Star Wars.
Answer:
Total Cost, C=$(16S +56)
Step-by-step explanation:
Chris buys 8 more Ninja Turtles than Star Wars action figures.
Cost of each Ninja Turtle = $7
Cost of each Star Wars = $9
Let number of Star Wars bought = S
As per question statement, number of Ninja Turtles bought = S+8
Cost of 'S' number of Star Wars = Number of Star Wars bought [tex]\times[/tex] cost of each Star Wars
Total cost of Star Wars bought = S [tex]\times[/tex] 9 or $9S
Similarly, Cost of 'S+8' number of Ninja Turtles = Number of Ninja Turtles bought [tex]\times[/tex] cost of each Ninja Turtles
Total cost of Ninja Turtles bought = (S+8) [tex]\times[/tex] 7 or $(7S +56)
Total Cost of the purchase = Total cost of Star Wars Bought + Total cost of Ninja Turtles bought
Total Cost of the purchase, C = 9S + (7S +56)
[tex]\Rightarrow C=\$(16S +56)[/tex]
Answer:

The point-stope form of the equation of the line that passes through (-5. -1) and (10.-7) is y+7= -2/5(x-10). What is the standard form of the equation for this line?
2x - 5y = -15
2x - 5y = -17
2x + 5y = -15
2x - 5y = -17
Answer:
2x+5y = -15
Step-by-step explanation:
y+7= -2/5(x-10)
Multiply each side by 5 to get rid of the fraction
5(y+7)= 5*-2/5(x-10)
5(y+7)= -2(x-10)
Distribute
5y+35 = -2x+20
Add 2x to each side
2x+5y +35 = 2x-2x+20
2x+5y +35 = 20
Subtract 35 from each side
2x+5y+35-35 = 20-35
2x+5y = -15
