Answer:

Step-by-step explanation:

Given

w is the classmate's weight in pounds

h is the height

The general formula for the expression is y = MX+c where

m is the slope

c is the intercept

M is the change in y to change in x

Comparing with the given equation

w = 6.5h - 275, we will see that the slope of the equation is 6.5 and can be expressed as the change in the classmate's height to the classmate's weight

slope = dh/dw = 6.5

A hot air balloon is flying at a constant speed of 20 mi/h at a bearing of N 36° E. There is a 10mi/h crosswind blowing due east

crimeas [40]

Answer:

Step-by-step explanation:

v = {[(20sin36°)i + (20cos36°)j] + 10i} mi/h

vE = 20sin36º + 10 = 21.76 mi/h

vN = 20cos36° = 16.18 mi/h

v = √(vE2 + vN2) = √(21.762 + 16.182) mi/h = 27.12 mi/h

θ = tan-1(vN/vE) = tan-1(16.18/21.76) = 36.6º north of east

Hi there! :)

Answer:

$\huge\boxed{x = 10,000}$

Given:

$logx = 4$

The given expression is a logarithm with a base of 10, therefore we can rewrite this as:

$10^{4} = x$

Evaluate:

$x = 10,000$

Reika [66]

Answer:

74.7 km/h

Step-by-step explanation:

The computation of the average speed is shown below:

As we know that

Speed = Distance ÷ Time

where

Distance = 66 km

And, the time is from 14.54 to 15.47 is 53 minutes

So, the speed is

= 66 km ÷ 53 minutes

= 74.71698 kilometers per hour

= 74.7 km/h

Answer:

$\boxed{x = 3}$

Step-by-step explanation:

${5}^{2} = {4}^{2} + {x}^{2} \\ {x}^{2} = {5}^{2} - {4}^{2} \\ {x}^{2} = 9 \\ x = \sqrt{9} \\ x = 3$
