A Ferris wheel has a radius of 35 m. Its center is 36 m above the ground. It rotates once every 60 s. Suppose you get on the bot

tom at t = 0 .
Write an equation that expresses your height as a function of elapsed time.

h = 36 cos 2π (t - 30) / 60 + 35

h = 60 cos 2π (t - 35) / 36 +60

h = 35 cos π (t - 30) / 60 + 36

h = 35 cos 2π (t - 30) / 60 +36

Jessica buys a lamp that costs $35 and a table that costs $75.00. If the tax rate is 10%, what will be the total cost of the lam
shepuryov [24]
Hello there!

75 + 35 = 110

110 x 10% = 0.1

110 x 0.1 = 11 ( the 11 is your tax )

75 + 35 = 110

110 + 11 = 121

$121 

Hope this helped!

The estimated regression equation obtained is :

y = b0 + b1x

b0 = 82.82967

b1 = 3.46061

ŷ = 3.46061X + 82.82967

The change in annual sales for every year of experience is given by the slope value, b1 = 3.46061 = 3.5 (1 decimal place)

The Coefficient of determination R² = 0.8477 = 0.848 ( 3 decimal place).

The Coefficient of determination gives the proportion of explained variance.

About 84.8% percent variation in annual sales can be explained by years of experience of the sales person.

Using the regression equation :

ŷ = 3.46061X + 82.82967

Years of experience, x = 8

ŷ = 3.46061(8) + 82.82967 = 110.514

111 = (to the nearest whole number)
