Shifting down 4 means you are taking away 4.
F(x) = g(x) - 4 = 3x^2 - 4
Answer:
87.92 in²
Step-by-step explanation:
pi × (R² - r²) = area
Where R is the radius of the outer circle and r of the inner circle.
Since C = 2pi×r
37.68 = 2×3.14×r
r = 6 in
R = 6 + 2 = 8 in
Therefore,
pi × (R² - r²) = area
Area = 3.14 (8² - 6²)
= 87.92 in²
Y = 2x - 3
y = (slope)x + (y-intercept)
slope is rise over run which is up 6 over right 3 ... slope = 2
y-intercept is where the graph crosses y-axis ... y-intercept = -3
Answer:
y+7= -6/5(x+3)
Step-by-step explanation:
Point slope form for a line is given by
y-y1 = m(x-x1) where m is the slope and (x1, y1) is a point on the line
y - -7 = -6/5(x - -3)
y+7= -6/5(x+3)
