No they did not, to have been working at the same rate it should have taken Heath 90 minutes to complete 18 problems, as 6x3 is 18, you would also multiply the time completed by 3, hope this helps

Kiera : 30/6 = 5 minutes per problem
Heath : 40/18 = 2.22 minutes per problem

They did not work at the same rate....Heath worked faster

A circle has a diameter of 15 cm. Find the circumference. . Use 3.14 for π. Round your answer to the nearest tenth. PLEASE HELP!
8_murik_8 [283]

Answer:

47.1 cm

Step-by-step explanation:

<u>The formula for finding circumference is πd. So, plug in the given values and simplify the expression:</u>

d = 15

π = 3.14

15 × 3.14 = 47.1

<u>The circumference of a circle with a diameter of 15 cm and using 3.14 as a substitute for π will be </u><u>47.1 cm</u><u>.</u>

Help me find the range of this function please
lara31 [8.8K]

Answer:

{-2, -14, -26, -50}

Step-by-step explanation:

The range of the function is the function evaluated at each point of the given domain. So to find the range of the function we need to find the value of the function for each point in the domain:

- For x = -8

f(x)=-2x-18

f(-8)=-2(-8)-18

f(-8)=16-18

f(-8)=-2

The first value of the range of the function is -2

- For x = -2

f(x)=-2x-18

f(-2)=-2(-2)-18

f(-2)=4-18

f(-2)=-14

The second value of the range is -14

- For x = 4

f(x)=-2x-18

f(4)=-2(4)-18

f(4)=-8-18

f(4)=-26

Th third values of the range is -26

- For x = 16

f(x)=-2x-18

f(16)=-2(16)-18

f(16)=-32-18

f(16)=-50

The fourth and last value of the range is -50

Now we can put all the values of the range together

The range of the function is {-2, -14, -26, -50}
