What is the length of AC?

Alenkasestr [34]

So in order to find line AC you must find line AD and DC then plus them together.

to find AD use Pythagoras theorem
a^2 = c^2 - b^2
AD^2 = 7.5^2 - 6.5^2
AD^2 = 56.25 - 42.25
AD^2 = 14
square root both sides to get rid of the ^2
AD ≈ 3.7 or 3.74

Do the same for DC
DC^2 = 10^2 - 6.5^2
DC^2 = 100 - 42.25
DC^2 = 57.75
DC ≈ 7.6

now plus AD and DC which should give u 11.3

What is 0.123 rounded to the nearest hundredth

Sholpan [36]

You would round to 0.12, What you would do is look at the placement of each number. The 1 is in the tenths place, the 2 is in the hundreds and the 3 is in the thousands. So you look at the three and see if you would round up or down, if it is 5 or greater you round up if it is 4 or less then round down. This is less so you would round down to 0.12

A solid right (noncircular) cylinder has its base R in the xy-plane and is bounded above by the paraboloid zequalsx2plusy2. Th

Aleonysh [2.5K]

Answer:

a. V = 4/3

b. See attachment

Step-by-step explanation:

Given

Z = x² + y²

V = ∫ ∫ (x² + y²) dxdy {0,1}{0,y} + ∫ ∫ (x² + y²) dxdy {0,1}{x,2-x}

V = ∫ ∫ (x² + y²) dxdy {0,1}{x,2-x}

Integrate with respect to y

V = ∫ x²y+ y³/3 dx {0,1}{x,2-x}

V = ∫ x²(2-x) + (2-x)³/3 - x²(2) - (2)³/3 dx {0,1}

V = ∫ 2x² -7x³/3 + (2-x)³/3 dx {0,1}

V = 2x³/3 - 7x⁴/12 + (2-x)⁴/12 {0,1}

V = (⅔ - 7/4 + 2/12) - (0-0+16/12)

V = 4/3
