Answer:

Step-by-step explanation:

We need two points to use the slope formula

(0,0) and ( 4,80)

The slope is given by

m = ( y2-y1)/(x2-x1)

= ( 80-0)/(4-0)

= 80/4

= 20

The slope is 20

The rate at which a professional tennis player used carbohydrates during a strenuous workout was found to be 1.7 grams per minut

Alex787 [66]

Answer:

m=1.7

C=68 gr

Step-by-step explanation:

Function Modeling

We are given a relationship between the carbohydrates used by a professional tennis player during a strenuous workout and the time in minutes as 1.7 grams per minute. Being C the carbohydrates in grams and t the time in minutes, the model is

$C=1.7t$

The slope m of the line is the coefficient of the independent variable, thus m=1.7

The graph of C vs t is shown in the image below.

To find how many carbohydrates the athlete would use in t=40 min, we plug in the value into the equation

$C=1.7\cdot 40=68\ gr$

What is the value of the expression?

victus00 [196]

To solve this we are going to use the unitary circle and the fact that $tan \alpha = \frac{sin \alpha }{cos \alpha }$

From our circle we can infer that $sin\frac{5 \pi }{3}= \frac{- \sqrt{3} }{2}$ and $cos\frac{5 \pi }{3}= \frac{1}{2}$ .

Since $tan \alpha = \frac{sin \alpha }{cos \alpha }$ , $tan\frac{5 \pi }{3}= \frac{\frac{- \sqrt{3} }{2}}{\frac{1}{2} }$
$tan\frac{5 \pi }{3}=- \sqrt{3}$

We can conclude that $tan\frac{5 \pi }{3}=- \sqrt{3}$ .

If a circle has a diameter of 24 inches, which expression gives its area in

nexus9112 [7]

Answer:

D. 12²•π

Step-by-step explanation:

Area of a circle = πr²

Radius (r) = ½ of diameter = ½*24 = 12 inches

Plug in the value into the area

Area = π * (12)²

Area = π * 12²

Area = 12²•π
