Write two numbers that are multilied together to get to 75 but are added together to get 10?

1 answer:

7 0

Find all factor pairs of 75, add them to see which ones add to 10
75+1=76, nope
25+3=28, nope
15+5=20, nope
false, the smallest numbers are the sqrt of 75, but they are about 8, and 8+8=16 which is more than 10

there are no 2 numbers

Answer:

$\frac{1}{25}$

Step-by-step explanation:

Using the rule of exponents

$a^{-m}$ = $\frac{1}{a^{m} }$ , hence

f(- 2) = $5^{-2}$ = $\frac{1}{5^{2} }$ = $\frac{1}{25}$

A laptop computer is purchased for $2350. After each year, the resale value decreases by 35% . What will the resale value be aft

pentagon [3]

$\qquad \textit{Amount for Exponential Decay} \\\\ A=P(1 - r)^t\qquad \begin{cases} A=\textit{current amount}\\ P=\textit{initial amount}\dotfill &2350\\ r=rate\to 35\%\to \frac{35}{100}\dotfill &0.35\\ t=years\dotfill &4\\ \end{cases} \\\\\\ A=2350(1 - 0.035)^{4}\implies A=2350(0.965)^4\implies A\approx 2037.87$
