Answer:
(x -1)² +(y -4)² = 25
Step-by-step explanation:
The equation of a circle in standard form is ...
(x -h)² +(y -k)² = r² . . . . . . . circle with center (h, k) and radius r
The graph shows your circle has its center at (1, 4) and its radius is 5. Then the equation is ...
(x -1)² +(y -4)² = 25
Radius= 7cm
Base area= 49pi
Volume= 49pi*4= 196pi=615.75cm^3
Answer:
The answer is 61.
Step-by-step explanation:
Let, the numbers are: x, (x+2), (x+4)
Now, x+x+2+x+4 = 183
3x + 6 = 183
3x = 177
x = 59
So, second number would be: (x+2) = (59+2) = 61
G=gas
w=bottle of water
8g + 2w = 29
12g + 4w = 45
I'm going to use elimination to cancel out the variable w by multiplying the first equation by -2.
-16g - 4w = -58
12g + 4w = 45
-4g = -13
/-4 /-4
g = 3.25
Now plug it into an equation, any equation.
8 (3.25) + 2w = 29
26 +2w=29
w=1.5
Now to check, plug it into both equations if you want.
12 (3.25) + 4 (1.5)=45
39 + 6=45
One bottle of water is $1.50, while one gallon of gas is $3.25.
