The table below represents the velocity of a car as a function of time.

1 answer:

4 0

We plot these data where x corresponds to the time and y corresponds to the velocity. Using the calculator, y - intercept is equal to 50. y-intercept is the y-value when x is zero. The car is accelerating. The average rate of change when x =1 to x=3 is (56-52)/(3-1) or 2 miles/hour^2. The car would reach 60 miles/hour when x=5 from the acceleration of 2. Domain is 5.

Which is the correct input-output table for the function ?f(x)=3/x+4

Amanda [17]

It seems the function f(x) is 3/(x+4).

If the function is f(x) = 3 / (x + 4), a table could be

x f(x)

-8 -3/4

-7 -1

-6    -3/2

-5    -1

(-4 is no a valid input)

- 3 3

- 2    3/2

-1    1

0 3/4

1    3/5

2    3/6 = 1/2

3    3/7

4    3/8

If the function is f(x) = (3/x) + 4

Just substitute different values for x and obtain the respective outputs. In this case, x has to be different of o, i.e. 0 is not a valid input.

The first side of a triangle is 2 inches shorter than the second side. The third side is 5 inches longer than the second side. I

fomenos

Let the length of second side be x" ,

So,
Length of first side = 2" shorter than second = ( x - 2 )"
Length of third side = 5" longer than second = ( x + 5 )"

=×=×=×=×=×=×=×=×=×=×=×=×=×=×=×=×=

$\text{Perimeter = sum of all sides }$

Given, perimeter = 33"

= > first side + second side + third side = 33"

= > ( x - 2 ) + x + ( x + 5 ) = 33

= > x - 2 + x + x + 5 = 33

= > 3x + 3 = 33

= > 3x = 30

$= \: > x = \frac{30}{3}$

= > x = 10

Hence, length of each side is

First side = ( x - 2 )" = ( 10 - 2 )" = 8 inches

Second side = x " = 10 inches

Third side = ( x + 5 )" = ( 10 + 5 )" = 15 inches
