Answer:

Step-by-step explanation:

From the figure, it is given that AB≅ED, BC≅CD and ∠CAD≅∠CEB.

Now, from ΔACD and ΔECB, we have

Statements Reason

1. AB≅ED, BC≅CD Given

2. ∠CAD≅∠CEB. Given

3. AB=ED, BC=DC Definition of congruent segments

4. AB+BC=AC and Segment addition postulate

ED+DC=CE

5. ED+DC=AC and Substitution property

ED+DC=CE

6. AC=CE Substitution property

7. AC≅CE Definition of congruent segments

8. ∠C≅∠C Reflexive property

9. ΔACD≅ΔECB ASA rule of congruency

Hence proved.

Hence, option A is correct.

A hurricane is predicted to hit the coast in 5 days. Supplies are expected to dwindle as people prepare. The manager of the hard

Anton [14]

To test if linear model, we fit the data into a line and solve for the correlation coefficient:
The equation is
y = -1537.5x + 5466.67
and the correlation coefficient is
R² = 0.964

The model can't be exponential growth since the daily supply decreases with time. So, the data is tested if it's exponential decay. The same procedure is done the exponential equation would be linearized in the form:
y = -2816.06 lnx + 4073.57
with correlation coefficient of
R² = 0.998

Since the correlation coefficient for the exponential decay model is closer to 1, it must be the right model.

Xcel energy uses the equation c (x) =7.1+23logx to determine the cost of electricity for x hours. A. What would the function c^-

Sergeeva-Olga [200]

Answer:

Step-by-step explanation:

Note that the cost function is $c(x) = 7.1+23\ln(x)$ , which gives us the cost of electricity for x hours of consumption

a). The function $c^{-1}(x)[tex] which is the inverse function, tells us given a cost, the amount of hours we can consume electricty. b) Consider the equation [tex]y=7.1+23\ln(x)$

To find out the inverse function, we interchange the labels of x and y and solve for y, that is

$x = 7.1+23\ln(y)$

when solved for y we have

$e^{\frac{x-7.1}{23}}= y$

So the inverse function is given by $c^{-1}(x) = e^{\frac{x-7.1}{23}}$ .

c) We will use the inverse function to find the amount of hours the customer can use eelectricity. It is simple obtained by evaluating the inverse function at the desired cost (i.e $c^{-1}(15)$ )
