Answer:
1/64
Step-by-step explanation:
To get from a₄ to a₉, we multiply a₄ by r⁵ (since 9 - 4 = 5). We know a₄ and r = 1/2 so the answer is 1/2 * (1/2)⁵ = 1/64.

Answer:
50
Step-by-step explanation: 50 is the only number that you can't multiply by two of the same whole number.
Given:
(7,0), (10,21)
To find the slope of the line that passes through the given points, we use the formula:
![m=\frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
where:
m=slope
Based on the given points, we let:
We plug in what we know:
![\begin{gathered} m=\frac{y_2-y_1}{x_2-x_1} \\ =\frac{21-0}{10-7} \\ \text{Simplify} \\ m=\frac{21}{3} \\ m=7 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20m%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D%20%5C%5C%20%3D%5Cfrac%7B21-0%7D%7B10-7%7D%20%5C%5C%20%5Ctext%7BSimplify%7D%20%5C%5C%20m%3D%5Cfrac%7B21%7D%7B3%7D%20%5C%5C%20m%3D7%20%5Cend%7Bgathered%7D)
Therefore, the answer is A. The slope is 7.
