Scilla [17]

Answer:

Sin B = 5/13

Cos B = 12/13

tan A = 12/5

Step-by-step explanation:

Sin B = opposite side/ hypotenuse

Sin B = 5/13

Cos B = adjacent side / hypotenuse

= 12/13

tan A = opposite side /adjacent side

Identify the variation as direct, inverse, joint or combined. y = cx²

viva [34]

Answer:

combined variation

Step-by-step explanation:

we have

$y=cx^{2}$

we know that

a)<u> in the interval </u>----> (0,∞)

If the value of x increase the value of y increase

Is a direct variation

b) <u>in the interval -</u>---> (-∞,0)

If the value of x increase the value of y decrease

Is a inverse variation

therefore

Is a combined variation

Help meeeeeeeeeeee:(

Vaselesa [24]

Answer:

1/3

Step-by-step explanation:

(1/3)^2x(1/3)^-1

so, we can write this as:

1/3 x 1/3 x 3/1

if calculated by cutting, the answer is 1/3

There is also an easier way to do this,

(1/3)^2 x (1/3)^-1

as the bases are same, the powers will be added.

2+(-1)

2-1

so,

(1/3)^1 or 1/3

Below are the rates of travel of 4 shipping trucks. Which truck drove the fastest rate? Truck A: 300 miles in 4 hours Truck B: 2

Tasya [4]

Answer:

Truck D.

Step-by-step explanation:

Below are the rates of travel of 4 shipping trucks.

Truck A: 300 miles in 4 hours Truck B: 240 miles in 3 hours Truck C: 325 miles in 5 hours Truck D: 170 miles in 2 hours.

Speed = distance/time

Speed of Truck A,

$v_A=\dfrac{300}{4}\\\\v_A=75\ mph$

Speed of Truck B,

$v_B=\dfrac{240}{3}\\\\v_B=80\ mph$

Speed of Truck C,

$v_C=\dfrac{325}{5}\\\\v_C=65\ mph$

Speed of Truck D,

$v_D=\dfrac{170}{2}\\\\v_D=85\ mph$

It can be seen that the speed of Truck D is more out of Trucks A,B and C. Hence, Truck D is moving at a faster rate.
