Answer: SI = $70
Step-by-step explanation:
SI = prt / 100
24 months = 2 years
= (875 x 4 x 2) / 100
= 70
Answer: 5
Step-by-step explanation:
0.666... is equal to 2/3 and 0.75 is equal to 3/4. 2/3 x 3/4= 6/12 which simplifies to 1/2 or 0.5.
To divide, multiply the first number by the reciprocal of the second, so 2/3 x 4/3 = 8/9.
The short cut formula for finding equation of two points
(x₁, y₁) and (x₂, y₂)
is:
(y - y₁) / (y₂- y₁) = (x - x₁) / (x₂ - x₁).
Substituting: x₁ = -3, y₁ = 2, x₂ = 7, y₂ = -1
(y - 2) / (-1 - 2) = (x - -3) / (7 - -3)
(y - 2) / -3 = (x + 3) / (7 + 3)
(y - 2) / -3 = (x + 3) / 10
10*(y - 2) = -3*(x +3)
10y - 10*2 = -3*x - 3*3
10y - 20 = -3x - 9
10y + 3x = -9 +20
10y +3x =11
Hence equation is: 10y + 3x = 11
Hope this explains it.
One of the equations for a circle is (x - h)² + (y - k)² = r² where (h, k) are the center and r is the radius.
So after substitution:
(x + 6)² + (y - 2)² = 100
Notice the equation has the opposite of h and k and 100 is the result of squaring 10.
