Answer:

The equation required to find Width of rectangle is: \mathbf{24=2x+2}

Step-by-step explanation:

Area of rectangular table top =  24 ft^2

Let width of table = x

Length of table = x+2

We need to find equation that could be used to find the width (w) of the table top?

The formula used is: Area\:of\:rectangle=Length \times Width

Putting values in formula and finding the equation:

Area\:of\:rectangle=Length \times Width\\24=x+x+2\\24=2x+2\\

So, the equation required to find Width of rectangle is: \mathbf{24=2x+2}

The options given are not complete. So please verify your answer.

Paula Frye loaned $10,000 to her son's new business at 5% ordinary simple interest (360-day year). At the end of the loan period
faust18 [17]

Answer:

91 days

Step-by-step explanation:

Amount loaned = $10,000.

Interest rate = 5%

Paula received $125 as interest .

Since, the interest rate is 5% , One has to pay the 5% of total amount loaned in a year.

in  a year , he has to pay \frac{5}{100}×10,000 = $500.

But he paid $125 as interest , So,

Length of loan period = \frac{125}{500} Year  = \frac{1}{4}th Year  

                                     = 3 months

Thus, he paid the amount in 91 days. (Since one month will surely be of 31 days)

A quarterback throws a football to a teammate. The football is 6.5ft above the ground when it leaves the quarterback's hand. His
sergejj [24]

Answer:

y = - 16t² + 55.6t + 6

Step-by-step explanation:

Using y - y₀ = vt - 1/2gt² where g = 32 ft/s², and v the velocity of the football

So y = y₀ + vt - 1/2 × (32 ft/s²)t²

y = y₀ + vt - 16t² where y₀ = 6.5 ft

y = 6 + vt - 16t²

Now, when t = 3.5 s, that is the time the teammate catches the ball after the quarterback throws it, y = 5 ft. Substituting these into the equation, we have

5 = 6.5 + v(3.5 s) - 16(3.5 s)²

5 = 6.5 + 3.5v - 196

collecting like terms, we have

5 - 6.5 + 196 = 3.5v

194.5 = 3.5v

v = 194.5/3.5 = 55.57 ft/s ≅ 55.6 ft/s

So, substituting v into y, our quadratic model is

y = 6 + 55.6t - 16t²

re-arranging, we have

y = - 16t² + 55.6t + 6
