Find the interest on $4,000 at 3% for 4 months

Sladkaya [172]

Step-by-step explanation:

✧ $\underline{ \underline{ \large{ \tt{G \: I \: V \: E \: N}}}} :$

Principal ( P ) = $ 4000
Rate ( R ) = 3 %
Time ( T ) = 4 months = $\ \frac{4}{12}$

✧ $\underline{ \underline{ \large{ \tt{ T \: O \: \: F\: I\: N \: D}}}} :$

Interest ( I )

✧ $\underline{ \underline{ \large{ \tt{S \: O \: L \: U \: T \: I \:O\: N}}}} :$

☂ $\boxed{ \large{ \sf{Interest \: ( \: I \: ) = \frac{PTR}{100}}}}$

~Plug the known values and then simplify !

➝ $\large{ \bf{ \frac{4000 \times \frac{4}{12} \times 3}{100} }}$

➝ $\large{ \bf{ \frac{4000}{100}}}$

➝ $\large{ \bf{ \frac{4 \: 0 \: \cancel{0 \: 0}}{1 \: \cancel{ 0 \: 0}}}}$

➝ $\boxed{ \large{ \bf{ \$ \: 40}}}$

⟿ $\boxed{ \boxed{ \underline{ \large{ \text{OUR \: FINAL \: ANSWER }: \boxed{ \underline{ \tt{ \$ \: 40}} }}}}}$

A stone is thrown vertically upward from a platform that is 20 feet height at a rate of 160 ft/sec. Use the quadratic function h

Nutka1998 [239]

Check the picture below.

$\textit{vertex of a vertical parabola, using coefficients} \\\\ y=\stackrel{\stackrel{a}{\downarrow }}{-16}x^2\stackrel{\stackrel{b}{\downarrow }}{+160}x\stackrel{\stackrel{c}{\downarrow }}{+20} \qquad \qquad \left(-\cfrac{ b}{2 a}~~~~ ,~~~~ c-\cfrac{ b^2}{4 a}\right)$

$\left(-\cfrac{ 160}{2(-16)}~~~~ ,~~~~ 20-\cfrac{ (160)^2}{4(-16)}\right) \implies \left( - \cfrac{ 160 }{ -32 }~~,~~20 - \cfrac{ 25600 }{ -64 } \right) \\\\\\ \left( 5 ~~~~ ,~~~~ 20 +400 \right)\implies (\stackrel{seconds}{5}~~,~~\stackrel{feet}{420})$
