When working with scientific notation, what does a negative exponent let you know about the size of the number?

1 answer:

4 0

well, you saw it on the previous exercise, 8.25 x 10⁻⁶, it <u>looks</u> like 8.25 is some value between 1 and 10, but is not really, the 10⁻⁶ is disguising that is really much smaller than that, in fact much smaller than even 1.

Sholpan [36]

Answer:

14.67 gram

Step-by-step explanation:

Henry has two pixie sticks full of delicious sugar.

Now, each pixie stick contains 22 grams of sugary goodness, then in two sticks, there will be (22 × 2) = 44 grams of sugar.

Now, Henry shares two pixie sticks among two friends and himself in equal proportion.

Therefore, each of his friends will get $\frac{44}{3} = 14.67$ (Round to the nearest tenth) gram of sugary goodness. (Answer)

A particular isotope has a half-life of 74 days. If you start with 1 kilogram of this isotope, how much will remain after 150

shtirl [24]

$\bf \stackrel{150~days}{\textit{Amount for Exponential Decay using Half-Life}} \\\\ A=P\left( \frac{1}{2} \right)^{\frac{t}{h}}\qquad \begin{cases} A=\textit{accumulated amount}\\ P=\textit{initial amount}\dotfill &1\\ t=\textit{elapsed time}\dotfill &150\\ h=\textit{half-life}\dotfill &74 \end{cases} \\\\\\ A=1\left( \frac{1}{2} \right)^{\frac{150}{74}}\implies A=1\left( \frac{1}{2} \right)^{\frac{75}{37}}\implies \boxed{A\approx 0.24536}$

$\bf \stackrel{300~days}{\textit{Amount for Exponential Decay using Half-Life}} \\\\ A=P\left( \frac{1}{2} \right)^{\frac{t}{h}}\qquad \begin{cases} A=\textit{accumulated amount}\\ P=\textit{initial amount}\dotfill &1\\ t=\textit{elapsed time}\dotfill &300\\ h=\textit{half-life}\dotfill &74 \end{cases} \\\\\\ A=1\left( \frac{1}{2} \right)^{\frac{300}{74}}\implies A=1\left( \frac{1}{2} \right)^{\frac{150}{37}}\implies \boxed{A\approx 0.060202}$

An expression is shown.

Colt1911 [192]

Answer:

Step-by-step explanation:

(2x - 3) + [ 4x(3x + 2)]

2x - 3 + [ (4x*3x) + (4x*2) ]

2x - 3 + [ 12x² + 8x ]

2x - 3 + 12x² + 8x

12x² + 10x - 3
