91 divided by 7 is 13. so he can paint 13 in 1 week. 13 x 4 equals 52 so he can paint 52 portraits in 4 weeks.
Outer radius: Ro = 11 m
Inner radius: Ri = 9 m
Area of the sidewalk: A = <span>π (Ro^2 - Ri^2)
A = </span><span>π ( (11 m)^2 - (9 m)^2 )
A= </span><span>π ( 121 m^2 - 81 m^2 )
A = </span><span>π ( 40 m^2 )
A= 40</span><span>π m^2
The exact area of the sidewalk is 40</span><span>π square meters
A = 40 (3.14) m^2
A = 125.6 m^2
The approcimate area of the sidewalk is 125.6 m^2</span>
Answer:
Step-by-step explanation:
if you are going in a negative direction or by a decimal you are contracting, so the image would get smaller. If you are going in a positive direction(has to be a whole number as well) you have an expansion.
Answer:
x = - 6
Step-by-step explanation:
The x-intercept is when y =0, you are looking for a point (x, 0)
So you replace y = 0 in the equation
4x - 3y = - 24
4x - 3(0) = - 24
4x = - 24
x = - 6
(a) The parabola opens downward.
(b) The axis of symmetry is at x = -2.
(c) The vertex is at (-2,0).
(d) The x-intercepts is (-2,0), and the y-intercept is at (0,-1).
