Use the distance formula to find the distance to the nearest 10th from R(7,-2) to w(-2,3).
Jlenok [28]

Answer:

10.3

Step-by-step explanation:

d = sqrt ((x2 - x1)^2 + (y2 - y1)^2)

(7,-2)....x1 = 7 and y1 = -2

(-2,3)...x2 = -2 and y2 = 3

now we sub

d = sqrt ((-2 - 7)^2 + (3 - (-2)^2)

d = sqrt ((-9^2) + (5^2))

d = sqrt (81 + 25)

d = sqrt (106)

d = 10.295 rounds to 10.3 <===

Let f be the function that determines the area of a circle (in square cm) given the radius of the circle in cm, r. That is, f(r)
yarga [219]

Answer:

The answers to each question are:

a)A=f(r=4cm)=50.26cm^2

b)\Delta A(10.91cm-10.9cm)=f(10.91cm)-f(10.9cm)=0.6851cm^2

c)C=5\cdot f(r=12.7cm)=2533.54cm^2

d)D=f(r=28cm)+59cm^2=2522.01cm^2

Step-by-step explanation:

The function f(r) that represents the area of a circle (in square cm) is:

f(r)=\pi r^2

a) To represent the area (in square cm) of a circle whose radius is 4 cm, you just have to evaluate the function with a radius of 4cm:

A=f(r=4cm)=50.26cm^2

b) To represent how much the area (in square cm) of a circle increases by when its radius increases from 10.9 to 10.91 cm, you have to represent the difference between the final area with a radius of 10.91cm and the initial area of a radius of 10.9cm:

\Delta A(10.91cm-10.9cm)=f(10.91cm)-f(10.9cm)=0.6851cm^2

c) To represent the area of 5 circles that all have a radius of 12.7 cm, we can use the function f(r) to represent the area of a circle with a radius of 12.7cm and multiply it for 5:

C=5\cdot f(r=12.7cm)=2533.54cm^2

d) To represent the area of the larger circle that is 59 square cm more than the first circle (with a radius of 28 cm), we can use the function f(r) to obtain the area of the first circle and addition 59 square cm:

D=f(r=28cm)+59cm^2=2522.01cm^2

Please help ????? Just the bottom question
torisob [31]

Answer:

144

Step-by-step explanation:

We can see that every 2 boxes has 24 peaches in it. That means that every single box would have 12 in it. Then it is just simple multiplication from there. 12 * 12 = 144.

Hope that this helps!

The mean hourly salary of the 10 employees at a fast­food restaurant is $8.25. One of the employees earning $6.50 an hour leaves
IgorC [24]
You would add $8.25 + $5.50, which equals $13.75. Then you would divide that number by the number of employees currently working at the fast food restaurant; $13.75 / 2 = $6.875. So, $6.88 would be the new mean salary of the employees.
