Answer:
26
Step-by-step explanation:
the function is f(x), and we need to find f(-2). the only difference between the two terms i gave is the -2 replacing the x. this means that you must replace every x in the first equation with -2. this makes the new function f(-2)=-9(-2)+8. after multiplying the -9 and -2 and adding that product to 8, you come up with your answer: 26.
Answer:
mean=14
median =4
Range=3
Step-by-step explanation:
Mean = 4+6+3+1+9+0+5/2
=28/2
=14
Median = ( N+1/2 )th item
= ( 7+1 )/2
= 8/2
= 4
Range = largest no- lowest no
= 9-6
= 3
Answer:
y >= 25 - 5x/3
Step-by-step explanation:
5x + 3y >= 75
-5x -5x
3y >= -5x + 75
3y/3 >= (-5x+75)/3
y >= 25 - 5x/3
Answer:
329.91 cm^2
Step-by-step explanation:
A ring-shaped region is shown below. Its inner radius is 8m, and its outer radius is 11m. 8m 11m Find the area of the shaded region. Use 3.14 for π. Do not round your answer.
Your answer
Given data
inner radius= 8cm
area= πr^2
area= 3.142*8^2
area= 3.142*16
area= 50.272 cm^2
outer radius= 11cm
area= πr^2
area= 3.142*11^2
area= 3.142*121
area= 380.182 cm^2
Hence the area of the shaded part is
=380.182-50.272
=329.91 cm^2
