Answer:
yes
Step-by-step explanation:
To determine if the point lies on the line substitute the coordinates into the left side of the equation and if equal to the right side then the point lies on the line
- 3 + (4 × 4) = - 3 + 16 = 13 = right side
Hence (- 3, 4) lies on the line x + 4y = 13
Rate of growing, r = 91.2/90 = 1.013
Salary, f(x) = Initial salary * (r)^ (years from 2005)
f(x) = 90(1.013)^x.
This is the second option.
Answer:
x=8.5
Step-by-step explanation:
3x+31=14+5x
17=2x
x=8.5
1) find the are of the circle: πr²
2) find the area of each triangle: (base x altitude)/2
3) subtract the triangles from the circle are
1) area of circle:π.5² = 25 π
2) Area of the triangle = (6 x 4)/2 =12 cm². We also notice that both triangles are congruent SSS (6,5 & 5), so the total surface of the 2 triangles = 24 cm²
3) (25π - 24) cm² is the answer
