Answer:

Step-by-step explanation:

hello :

cos²θ +sin²θ = 1 and cosθ =4/5

(4/5)² + sin²θ = 1 so : sin²θ = 1 - 16/25

sin²θ = 9/25 = (3/5)²

sinθ = 3/5 or sinθ = - 3/5 because : (3/5)²= (- 3/5)²= 9/25

The oxygen consumption (in milliliter per pound per minute) for a person walking at x mph is approximated by the function f(x)=\

Oliga [24]

Answer: Speed = 5.6 mph

Oxygen consumption = 71.6 mL/lb/min

Step-by-step explanation: For the oxygen consumption to be the same, functions must be equal:

f(x) = g(x)

$\frac{5}{3}.x^{2} + \frac{5}{3}.x+10=11x+10$

Resolving:

$\frac{5}{3}.x^{2} + \frac{5}{3}.x - 11x =0$

$\frac{5}{3}x^{2} + \frac{5}{3}x - \frac{33x}{3}=0$

$\frac{5}{3}x^{2} - \frac{28x}{3}=0$

$\frac{x}{3}(5x - 28)=0$

$\frac{x}{3} = 0$

x=0

5x - 28 = 0

$x = \frac{28}{5}$

x = 5.6

The speed when the oxygen consuption is the same is 5.6 mph.

For the level of oxygen consumption:

f(5.6) = g(5.6)

g(5.6) = 11*5.6 + 10

g(5.6) = 71.6

The level of oxygen consumption is 71.6 mL/lb/min
