Answer:
703.7 in²
Step-by-step explanation:
SA = 2πrh+2πr²
= 2×π×7×9+2×π×7²
= 224π
= 703.7 in² (rounded to the nearest tenth)
Answer:
option A is the correct answer
Answer:
- y = x - 6
- y = -x + 5
- y = x - 5
Step-by-step explanation:
<em>Slope - intercept formula: y = mx + b, where m- slope, b- y-intercept</em>
<u>1. Points are:</u>
<u>Slope is:</u>
- m = (y2 - y1)/(x2 - x1)
- m = (-2 - (-4))/(4 - 2) = 2/2 = 1
y-intercept is - 6 as per graph
<u>Then the formula is</u>
<u>2. Points are:</u>
<u>Slope is:</u>
- m = (1 - 5)/(4 - 0) = -4/4 = -1
y-intercept is 5 as per point
<u>Then the formula is</u>
<u>3. Points are:</u>
<u>Slope is</u>
- m = (3 - 1)/(-1 -(-3)) = 2/2 = 1
y-intercept is -5 as per graph
<u>Then the formula is</u>
