a roller skating rink offers a special rate for birthday parties. On the samr day, a party for 10 skaters cost $107 and a party

olga nikolaevna [1]

Answer:

$119

Step-by-step explanation:

Let

x -----> the number of skaters

y -----> the cost for birthday parties

we have the points

(10,107) and (15,137)

step 1

Find the slope of the linear equation

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

substitute the values

$m=\frac{137-107}{15-10}$

$m=\frac{30}{5}=6\ \frac{\$}{skater}$

step 2

Find the equation of the line in point slope form

$y-y1=m(x-x1)$

we have

$m=6\\point\ (10,107)$

substitute

$y-107=6(x-10)$

step 3

Convert to slope intercept form

$y-107=6x-60$

$y=6x-60+107$

$y=6x+47$

step 4

How much would a party for 12 skaters cost?

For x=12 skaters

substitute the value of x in the equation and solve for y

$y=6(12)+47$

$y=\$119$

The function h(t) = -4.922 +17.694+ 575 is used to model the height of an object being tossed from a tall building, where

wel

Correct question is;

The function h(t) = -4.92t ² + 17.69t + 575 is used to model an object being tossed from a tall building, where h(t) is the height in meters and t is the time in seconds. Rounded to the nearest hundredth, what are the domain and range?

Answer:

The domain and range are:

Domain: [0, 12.76]

Range: [0, 590.9]

Step-by-step explanation:

For the domain;

Let's find the root of the given function h(t) = -4.92t ² + 17.69t + 575.

We will do it by Equating h(t) to zero and using quadratic formula;

So;

-4.92t ² + 17.69t + 575 = 0

t = [-17.69 ± √(17.69² - 4(-4.92 × 575))]/(2 × -4.92)

Solving with a calculator, the roots are

t = -9.16 or t = 12.76

We ignore the negative root and make use of the positive root.

Thus, the domain is:

[0, 12.76]

For the range:

Let's find the derivative of the given function:

Thus;

h'(t) = -9.84t + 17.69

Again like we did for the domain, we will equate to zero to find t

Thus;

-9.84t + 17.69 = 0

t = 17.69/9.84

t ≈ 1.8

Thus, this is the time at which the object being tossed reaches the maximum height of the function.. Thus max height at t = 1.8 is;

h(1.8) = (-4.92 × 1.8²) + (17.69 × 1.8) + 575

h(1.8) = -15.9408 + 31.842 + 575

h (1.80) ≈ 590.9

So the range is; [0, 590.9]
