Answer:

C. 570.20 ft²

Step-by-step explanation:

Surface

A = 2·pi·r^2 + 2·pi·r·h

A = 2·pi·5.5^2 + 2·pi·5.5·11 = 570.20 ft²

Incomplete question as we have not told what to find.So I have assumed to find average CPI for each program.So complete question is here

Compilers can have a profound impact on the performance of an application. Assume that for a program, compiler A results in a dynamic instruction count of 1.0E9 and has an execution time of 1.1 s, while compiler B results in a dynamic instruction count of 1.2E9 and an execution time of 1.5 s.

Find the average CPI for each program given that the processor has a clock cycle time of 1 ns.

Answer:

$CPI_{A}=1$

$CPI_{B}=1.25$

Step-by-step explanation:

As we know CPU time given as

$CPU_{time}=instructions*CPI*Cycle_{time} \\So\\CPI=\frac{CPU_{time}}{instructions*Cycle_{time}}\\ Where\\Cycle_{time}=1*10^{-9}s\\ And\\executionTime=CPUtime$

For Compiler A

$CPI_{A}=\frac{CPU_{timeA} }{instruction_{A}*Cycle_{time} }\\CPI_{A}=\frac{1s}{10^{9}*1.0*10^{-9}s }\\CPI_{A}=1$

For Compiler B

$CPI_{B}=\frac{CPU_{timeB} }{instruction_{B}*Cycle_{timeB} }\\CPI_{B}=\frac{1.5s}{(1.2*10^{9})*(1.0*10^{-9}s) }\\CPI_{B}=1.25$

umka21 [38]

Painted Area: 72 in^2

Unpainted Border on all sides: ====> 4 in"

4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 = 72

Answer: =====> 66 inches

My Internet kept messing up on me here, but the Answer is 66 inches, Sorry I couldn't finish working out the problem, going to check out my internet. - Thanks - P.

Hope that helps!!!! : )

Ask Your Teacher Write out the form of the partial fraction decomposition of the function (See Example). Do not determine the nu

exis [7]

Answer:

Step-by-step explanation:

Given to ask the Teacher Write out the form of the partial fraction decomposition of the function

It is not necessary to find the coefficients

For decomposition of partial fractions the necessary condition is that the denominator should be in a position to be factored into atleast two factors.

Then only partial fraction is possible otherwise not.

Here

a) $\frac{x}{x^2+x-20}$
