At a local gas station regular gas line sale for $2.89 per gallon wow premium gas line sale for three dollars is in $.39 per gal

Allisa [31]

Answer:

$7.55

Step-by-step explanation:

We have been given that at a local gas station regular gasoline sale for $2.89 per gallon while premium gasoline sale for $3.39 per gallon. We are asked to find the amount saved by a person on buying 15.1 gallons of regular gasoline.

First of all, we will find amount saved on buying 1 gallon of regular gasoline as:

$\text{Savings from one gallon of regular gasoline}=\$3.39-\$2.89$

$\text{Savings from one gallon of regular gasoline}=\$0.5$

To find amount saved on buying 15.1 gallons of regular gasoline, we will multiply $0.5 by 15.1 as:

$\text{Savings from 15.1 gallons of regular gasoline}=\$0.5\times 15.1$ $\text{Savings from 15.1 gallons of regular gasoline}=\$7.55$

Therefore, a person will save $7.55 on buying 15. gallons of regular gasoline.

A model rocket is launched with an initial upward velocity of 100 ft/s. The rocket's height h (in feet) after t seconds is given

tamaranim1 [39]

$\bf \stackrel{h}{34}=100t-16t^2\implies 16t^2-100t+34=0\\\\\\ 8t^2-50t+17=0
\\\\\\
~~~~~~~~~~~~\textit{quadratic formula}
\\\\
\stackrel{\stackrel{a}{\downarrow }}{8}t^2\stackrel{\stackrel{b}{\downarrow }}{-50}t\stackrel{\stackrel{c}{\downarrow }}{+17}=0
\qquad \qquad 
t= \cfrac{ - b \pm \sqrt { b^2 -4 a c}}{2 a}$

$\bf t=\cfrac{ - (-50) \pm \sqrt { (-50)^2 -4(8)(17)}}{2(8)}\implies t=\cfrac{50\pm \sqrt{2500-544}}{16}
\\\\\\
t=\cfrac{50\pm\sqrt{1956}}{16}\implies t=\cfrac{50\pm\sqrt{4\cdot 489}}{16}\implies t=\cfrac{50\pm\sqrt{2^2\cdot 489}}{16}
\\\\\\
t=\cfrac{50\pm 2\sqrt{489}}{16}\implies t=\cfrac{25\pm \sqrt{489}}{8}\implies t\approx
\begin{cases}
5.88916805\\
0.36083195
\end{cases}$
