Answer:

x = -1.7, or x = -17/10

Step-by-step explanation:

f(x) = 9.2 + 6x + 1 is a linear function and as such (and because the slope is not zero) has only one solution.  Combining like terms, we get

f(x) = 10.2 + 6x = 0 (you must set this equal to zero if solving for zero(s).

Then 6x = -10.2, and x = -1.7, or x = -17/10

What does the slope of the graph show about Emma's typing speed?
AleksAgata [21]

Answer:

Emma types at a rate of 45 words per minute.

Step-by-step explanation:

I know this because if you divide 90/2 you can get 45 because as you see on the graph, every two minutes is 90 words, so just divide 90/2.

What is the approximate radius of a sphere with a volume of 34 cm3?​
xz_007 [3.2K]

Answer:

<h2>2.01 cm</h2>

Step-by-step explanation:

The formula of a volume of a sphere:

V=\dfrac{4}{3}\pi R^3

<em>R</em><em> - radius</em>

<em />

We have

V=34\ cm^3

Substitute:

\dfrac{4}{3}\pi R^3=34    <em>multiply both sides by 3</em>

3\!\!\!\!\diagup^1\cdot\dfrac{4}{3\!\!\!\!\diagup_1}\pi R^3=(3)(34)

4\pi R^3=102         <em>divide both sides by 4</em>

\dfrac{4\pi R^3}{4}=\dfrac{102}{4}

\pi R^3=\dfrac{51}{2}          <em>divide both sides by π</em>

\dfrac{\pi R^3}{\pi}=\dfrac{\frac{51}{2}}{\pi}

R^3=\dfrac{51}{2\pi}   <em>use π ≈ 3.14</em>

\R^3\approx\dfrac{51}{(2)(3.14)}

R^3\approx\dfrac{51}{6.28}\\\\R^3\approx8.121\to R\approx\sqrt[3]{8.121}\\\\R\approx2.01\ cm
