Find the horizontal distance of a soccer ball being kicked at a 40 degree angle with a velocity of 50 feet per second, to the ne

grin007 [14]

Answer:

77 ft

Step-by-step explanation:

The horizontal distance is the range and it is a projectile motion.

So, range R = u²sin2θ/g where u = velocity = 50 ft/s, g = acceleration due to gravity = 32 ft/s² and θ = projection angle = 40°.

Substituting the values of the variables into the equation, we have

R = u²sin2θ/g

= (50 ft/s)²sin2(40°)/32 ft/s²

= (2500 ft²/s²)sin80°/32 ft/s²

= (2500 ft²/s²) × 0.9848/32 ft/s²

= 2462.02 ft²/s² ÷ 32 ft/s²

= 76.94 ft

≅ 77 ft to the nearest foot

Fill in the blank with a constant, so that the resulting expression can be factored as the product of two linear expressions: 2a

sdas [7]

Answer:

-15

Step-by-step explanation:

We proceed as follows;

In this question, we want to fill in the blank so that we can have the resulting expression expressed as the product of two different linear expressions.

Now, what to do here is that, when we factor the first two expressions, we need the same kind of expression to be present in the second bracket.

Thus, we have;

2a(b-3) + 5b + _

Now, putting -15 will give us the same expression in the first bracket and this gives us the following;

2a(b-3) + 5b-15

2a(b-3) + 5(b-3)

So we can have ; (2a+5)(b-3)

Hence the constant used is -15

A postal service requires that any box sent by priority mail have length plus girth (distance around) totaling no more than 104

Vaselesa [24]

Answer:

The length is no more than 56 inches.

The volume of the box is 8064 cubic inches.

Step-by-step explanation:

Given : A postal service requires that any box sent by priority mail have length plus girth (distance around) totaling no more than 104 in. One volume that meets this condition is contained by a box with a square end 12 in. on each side.

To find : What is the length of the box? What is the volume?

Solution :

A square end 12 inch on each side.

Then the girth of the box is given by,

$P=4\times s$
