Answer:
did anyone figure this out
Answer:
question 19 = no solution because not enough information
question 20 = 18 for volume
Step-by-step explanation:
question 19:
cylinder formula
surface A =2πrh+2πr2
2π times 9 times 7 + 2π times 9 times 2
SA = 508.938009882
volume equals 395.840674352
question 20:
biggest one,
4h﹣a4+2(ab)2+2(ac)2﹣b4+2(bc)2﹣c4
V=18 IS the volume
Answer:
2 .The slope of Function A is less than the slope of Function B
Step-by-step explanation:
A graph of Function A shows it has a y-intercept of 4, the same as that of Function B. (Statements 3 and 4 are not correct.)
The slope of Function A is 2, which is less than the slope of 3 that Function B has. (Statement 2 is correct; statement 1 is not.)
_____
<em>More detailed working</em>
The slope of Function A can be figured easily between the points with x-values that differ by 1:
m = (y3 -y2)/(x3 -x2) = (24-22)/(10-9) = 2/1 = 2 . . . . . Fun A has slope of 2.
The slope of Function B is the coefficient of x in the equation: 3.
__
The y-intercept of Function A can be found starting with point-slope form:
y -22 = 2(x -9)
y = 2x -18 +22
y = 2x +4 . . . . . . . slope-intercept form
The intercept of +4 is the same as that of Function B.
Part 1)
A foot is 12 inches so 5 feet is 60 inches.
First, you have to divide 216 by 18.(miles)
Next, since 5 feet is 60 inches, multiply the quotient by 60.(inches)
The two cities are 720 inches apart on the map.
Part 2)
The ratio to cups of flour to cups of sugar is 3:4
First, divide 7.5 by 3.(flour)
Next, multiply the quotient by 4.(sugar)
You need 10 cups of sugar for the recipe if 7.5 cups of flour is used.
I hope this helps because I spent a lot of time on it c:
