We can most easily solve this by simply inserting the known values and solving.

This is saying that x=1 and y=3. Lets replace the variables with them to solve.

Our equation is now 5(1)+3 is less than or equal to to -3.

Solve.

5+3

8 is definitely tly NOT less than -3. It is 11 more than it. The answer is no.

Hope this helps!

Use the position equation given below, where s represents the height of the object (in feet), v0 represents the initial velocity
iris [78.8K]

Answer:

(a) 7.5 seconds

(b) The horizontal distance the package  travel during its descent is 1737.8 ft

Step-by-step explanation:

(a) The given function for the height of the object is s = -16·t² + v₀·t + s₀

The initial height of the object s₀ = 900 feet

The initial vertical velocity of the object v₀_y = 0 m/s

The time it takes the package to strike the ground is found as follows;

0 = -16·t² + 0×t + 900

900 = 16·t²

t² = 900/16 = 62.25

t = √62.25 = 7.5 seconds

(b) Given that the horizontal velocity of the package is given as 158 miles/hour, we have

158 miles/hour = 231.7126 ft/s

The horizontal distance the package  covers in the 7.5 second of vertical flight = 231.7126 ft/s × 7.5 s = 1737.8445 feet = 1737.8 ft to one decimal place

The horizontal distance the package  travel during its descent = 1737.8 ft.

Koran is spending $12 on games and rides at another carnival, where a game costs $0.25 and a ride costs $1.
Vlad [161]

Answer:

0.25x+y=12

Step-by-step explanation:

Let

y ----> the number of rides

x ---> the number of games

we know that

The number of rides multiplied by  $1 plus the number of games multiplied by $0.25 must be equal to $12 (the dollar amount Koran is spending)

so

The equation that represent this situation is

0.25x+y=12

A cube in Emily's closet where she stores her jewelry has a side length of 1 1/4 feet.
Gnom [1K]

<u>Answer:</u>

1.95 cubic feet

<u>Step-by-step explanation:</u>

We are given that Emily stores her jewelry in a cube and the cube has a side length of 1\frac{1}{4} feet.

1\frac{1}{4} feet in an decimal form is 1.25 feet.

We know that,

<em>volume of a cube = s^{3}</em>

where <em>s</em> is the side length of the cube.

So substituting this value of side length of cube in the formula to get:

Volume of cube = (1.25)^3 = 1.95 feet
