Answer:

The percentage decrease in the depth is 45%

Step-by-step explanation:

January, lake depth = 1086 feet

august, lake depth = 597.3 feet

The decrease in depth = 1086 - 597.3

= 488.7 feet

Percentage decrease = decrease over January lake depth multiply by 100%

% decrease = (488.7/1086)*100%

=0.45*100%

= 45%

In circle D with m \angle CDE= 122m∠CDE=122 and CD=6CD=6 units, find the length of arc CE. Round to the nearest hundredth.
antoniya [11.8K]

Answer:

12.78 units

Step-by-step explanation:

The formula for arc length =

2πr × θ/360

From the question:

θ = 122°

r = 6 units

Therefore, the arc length =

2 × π × 6 × (122/360)

= 12.775810125 units

Approximately to the nearest hundredth = 12.78 units

Therefore, the length of arc CE is 12.78 units

Write an equation in slope -intercept form of the line that passes through (4,6) and (-8,3)
SpyIntel [72]

\bf (\stackrel{x_1}{4}~,~\stackrel{y_1}{6})\qquad (\stackrel{x_2}{-8}~,~\stackrel{y_2}{3}) ~\hfill \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{3}-\stackrel{y1}{6}}}{\underset{run} {\underset{x_2}{-8}-\underset{x_1}{4}}}\implies \cfrac{-3}{-12}\implies \cfrac{1}{4}

\bf \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{6}=\stackrel{m}{\cfrac{1}{4}}(x-\stackrel{x_1}{4}) \\\\\\ y-6=\cfrac{1}{4}x-1\implies y=\cfrac{1}{4}x+5

4, 8, 16, 32, __, ...​
Westkost [7]

Step-by-step explanation: To find the next two terms in the pattern shown here, notice that we multiply by 2 to get from 4 to 8. Next we multiply 8 by 2 to get 16 and then we multiply by 2 to get from 16 to 32.

Continuing with the same pattern, we would next multiply 32 by 2 and would end with a product of 64. Finally we would multiply 64 by 2 and we would end up with a product of 128.

With this pattern, we can say that we will multiply 2 by each number that is in our pattern in order to get our next number in the pattern.
