Answer:

C = 97.20

Step-by-step explanation:

Given that C varies as r² then the equation relating them is

C = kr² ← k is the constant of variation

To find k use the condition C = 202.80 when r = 2.6

k = $\frac{C}{r^{2} }$ = $\frac{202.8}{2.6^{2} }$ = 30

C = 30r² ← equation of variation

When r = 1.8, then

C = 30 × 1.8² = 97.20

What is the slope of the line that contains the points (4,-1) and (-1,4)?

fiasKO [112]

If you follow the slope formula your answer should be -1
proof:
slope formula: Y2-Y1/X2-X1=Slope (M)
4,-1 will be our x1,y1 and -1,4 will be our x2,y2
plug in numbers into formula: 4-(-1)/ -1-4
simplify you get 5/-5
simplify again and your answer is -1!!!
If its wrong im sorry

Help me with #4

Sladkaya [172]

Step-by-step explanation:

a. lim(x→2) [g(x) + h(x)]

Use additive property of limits.

= lim(x→2) g(x) + lim(x→2) h(x)

= 0 + 5

= 5

b. lim(x→2) [3 h(x)]

Use multiplication property of limits.

= [lim(x→2) 3] [lim(x→2) h(x)]

= 3 lim(x→2) h(x)

= 3 (5)

= 15

c. lim(x→2) [g(x) h(x)]

Use multiplication property of limits.

= [lim(x→2) g(x)] [lim(x→2) h(x)]

= (0) (5)

= 0

Gabriel interviewed his 30 classmates on whether or not they own a bike and live near a pool. He displayed his results in the tw

Answer:

The true statement is:

A) Over half of the bike owners live near a pool.

Step-by-step explanation:

See the attached table

According to the data of the table, we will check which statement is true.

A) Over half of the bike owners live near a pool.

The number of the bike owners = 8 + 7 = 15

The bike owners live near a pool = 8

The percentage of the bike owners live near a pool to all the bike owners= 8/15 = 0.533 > 0.5

The statement is true.

B) Less than 55% of his classmates live near a pool.

The number of classmates = 30

The number of classmates live near a pool = 8 + 10 = 18

The number of classmates live near a pool to all

classmates = 18/30 = 0.6 = 60% > 55%

The statement is wrong.

C) About 50% of his classmates don't live near a pool.

Don't live near a pool = live near a pool

So, the same explanation of statement B

The statement is wrong.

D) 2/3 of his classmates that live near a pool don't own a bike.

The number of classmates live near a pool = 8 + 10 = 18

The number of classmates live near a pool and don't own a bike = 10

The percentage of classmates live near a pool and don't own a bike to classmates live near a pool = 10/18 = 0.556 < 2/3

The statement is wrong.
