When a boy pulls his sled with a rope, the rope makes an angle of 70 with the horizontal. If a pull of 16 pounds on the rope is

alexandr1967 [171]

The horizontal component of force is 5.47 lb

Step-by-step explanation:

Given that a boy pulls his sled with a rope.

The rope makes an angle with horizontal = 70 degree

If a pull on the rope is needed to move the sled = 16 pounds

We need to find the horizontal component of force

In given scenario, the force used in this scenario is a vector addition of the horizontal and the vertical force component. The horizontal force component is calculated by multiplying the applied force by the cosine of the angle of the applied force from the horizontal plane in which it is found: horizontal force component = applied force x cos 70 degree

Horizontal component force = $f \cos \alpha$

Here, given applied force, f = 16 pounds

Then, horizontal component of force = $16 \cos 70^{\circ}$

Horizontal component of force = 16×0.342

Hence, horizontal component of force = 5.47 lb

Determine whether each function is an example of exponential growth or decay. then find the y-intercept. y=3(0.25)x

laila [671]

Answer: year 0 you get 3 * .25^0 = 3 * 1 = 3 year 2 you get 3 * .25^1 = 3 * .25 = .75 year 3 you get 3 * .25^2 = 3 * .0625 = .1875 the numbers are decreasing year after year so you are talking about decay. b^x increases as x increases if b is greater than 1. b^x stays the same as x increases if b is equal to 1. b^x decreases as x increases if b is greater than 0 and less than 1. x is assumed to be greater than or equal to 0.

Which formula should be used to find the area of the composite shape?

hoa [83]

The last option seems the best one: the figure is composed of a square/rectangle and a triangle. The area of the rectangle is the product of its dimension (i.e. $lw$ ), while the area of the triangle is half the product of the base and height ( $\frac{1}{2}bh$ ).

The sum of the two areas is the area of the composite shape.
