Y = -5/2(x + 4) + 7
y = -5/2x + (-10) + 7
y = -5/2x - 3
Answer:
160π cm²
Step-by-step explanation:
The area of the shaded region is
area of outer circle - area of inner circle
A = πr₁² - πr₂²
r₁ is the radius of the outer circle = 10 + 3 = 13 cm
r₂ is the radius of the inner circle = 3 cm
A = π × 13² - π × 3²
= π(169 - 9) = 160π cm² ≈ 502.65 cm² ( to 2 dec. places )
Answer:
y = 4/3x + 1.
Step-by-step explanation:
The equation of the lines passing through (2,1) and (6,7) is:
y - 7 = (7-1)/(6- -2)(x - 6)
y - 7 = 6/8(x - 6)
y = 3/4(x - 6) + 7
y = 3/4x + 5/2.
So the line perpendicular to it has slope -1/3/4 = -4/3:
y - 9 = -4/3(x + 6)
y = -4/3 x - 8 + 9
y = 4/3x + 1.
The answer is 117.5 because to find the interquartile range first u need to find the median. Then you fave to find the lower quartile which is 125 and thenearest u need to find the upper quartile which is 242.5. Finally u subtract 242.5 by 125 to get 117.5.
Hope it helped
Answer:
$15.75
Step-by-step explanation:
1.75 x 7 = 12.25
28 - 12.25 = 15.75
Add dollar sign. Final answer is $15.75
