Answer: The answer is 767.72 ft.

Step-by-step explanation:

You need to use tan since the problem requires u finding out the distance from the airport and ship and u only have the height of the balloon and the angle of depression. So then the equation becomes :

Tan21 = x/2000

Then you multiply by 2000 on both sides:

Tan21(2000) = x(2000)

The equation then becomes:

X= Tan21(2000)

so then x is: 767.72 ft

The horizontal distance is given by the formula:
tan θ=opposite/adjacent
where:
θ=21
opposite=2000 ft
adjacent=a
thus calculating for a we get:
tan 21=2000/a
thus
a=2000/tan 21
a=5210.18 ft

Answer: 5210.18 ft

<h3>How many pages should Claire read per day?</h3>

It follows from the task content that the number of pages which Claire should read per day in a bid to finish all 35 pages in 6 days be determined.

Since the given condition is such that; Claire reads an equal number of pages on each of the next six days.

It follows that the number of pages to be read each day is given by;

35 / 6

= 5.833 pages per day.

Ultimately, the number of pages Claire should read per day over the next 6 days is; 5.833 pages per day.

With Obesity on the rise, a Doctor wants to see if there is a linear relationship between the Age and Weight and estimating a pe
Romashka [77]

Answer:

112.569 ( D )

Step-by-step explanation:

Applying the estimated Regression Equation

y = b1X1 + b2X2 + a

b1 = ((SPX1Y)*(SSX2)-(SPX1X2)*(SPX2Y)) / ((SSX1)*(SSX2)-(SPX1X2)*(SPX1X2)) = 596494.5/635355.88 = 0.93884

b2 = ((SPX2Y)*(SSX1)-(SPX1X2)*(SPX1Y)) / ((SSX1)*(SSX2)-(SPX1X2)*(SPX1X2)) = 196481.5/635355.88 = 0.30925

a = MY - b1MX1 - b2MX2 = 149.25 - (0.94*61.31) - (0.31*193.88) = 31.73252

y = 0.939X1 + 0.309X2 + 31.733

For x1 ( age ) =39, and  x2(weight) =143

y = (0.93884*39) + (0.30925*143) + 31.73252= 112.569

where

Sum of X1 = 981

Sum of X2 = 3102

Sum of Y = 2388

Mean X1 = 61.3125

Mean X2 = 193.875

Mean Y = 149.25

attached is the Tabular calculation of the required values needed for estimated regression equation
