Eliminate the parameter t. Find a rectangular equation for the plane curve defined by the parametric equations.
djverab [1.8K]

Answer:

1. C

2. C

Step-by-step explanation:

1. x = \sqrt{t}\\, y = 4t +3

Solve for t:

t = x^{2}

Plug in t:

y = 4(x^{2} ) +3

y = 4x^{2} +3

2. x = 2t, y = t + 2

Solve for t:

t = x/2

Plug in t:

y = 1/2x + 2

in Youngstown, the population reached 4420 people in 1993. in 1998 the population was 5600 residents. what was the population in
Julli [10]
5600 - 4420 = 1180....so there is a difference of 1180 in a period of (1998 - 1993) = 5 yrs.

1180/5 = 236 people per yr

so in 1998 the population was 5600.....in 2000 (2 yrs later) the population would be : 5600 + 236(2) = 5600 + 472 = 6072 <==

A trampoline park charges $2 plus an hourly rate for each hour. The sign to the
MArishka [77]

The linear function that gives the cost of spending h hours at the park is given by:

C(h) = 2 + mh.

In which m is the hourly rate.

<h3>What is a linear function?</h3>

A linear function is modeled by:

y = mx + b

In which:

  • m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
  • b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.

The fixed rate is the y-intercept, hence, the linear function that gives the cost of spending h hours at the park is given by:

C(h) = 2 + mh.

In which m is the hourly rate.
