No. the two smaller numbers must add up to be greater than the largest number. the lengths you have would form two equal lines

Answer:

4: No

5: A

Step-by-step explanation:

4: The mapping does now represent a function. In a function each x value can only have 1 corresponding y value ( meaning that the x values can not repeat.) In the mapping the x value 3 corresponds with 2 y values therefore the mapping is not a function.

Formula for volume of a cylinder = $V=\pi r^2h$

Where r = radius and h = height

The cylinder shown has a given diameter of 22ft and a given height of 10ft

In order to use the formula we must convert the diameter to radius.

To do this we divide the diameter by 2 ( this is because the radius is equal to half the diameter )

so radius = 22/2 = 11

Now we plug in the dimensions into the formula

$V=\pi 11^210\\11^2=121\\121*10=1210\\1210\pi$

Remember, it says " Leave your answer in terms of pi," therefore we do not apply pi and leave it as 1210π

We can conclude that the answer is A

atroni [7]

Answer:

$ 30

$ 20

Step-by-step explanation:

Sea el costo fijo xy el costo por km sea y suponiendo que es el mismo para ambos taxis.

De la pregunta obtenemos las dos ecuaciones

$x+8y=190\quad ...(i)$

$x+5y=130\quad ...(ii)$

Aplicando $(i)-(ii)$

$8y-5y=190-130\\\Rightarrow 3y=60\\\Rightarrow y=\dfrac{60}{3}\\\Rightarrow y=20$

Sustituyendo en $(ii)$

$x+5y=130\\\Rightarrow x+5\times 20=130\\\Rightarrow x=130-100\\\Rightarrow x=30$

Entonces, el costo fijo es de $ 30 y el costo por km es de $ 20.
