Solution:

we are given with the function y = 2.5sec(x-5)

The plot of the given function can be found by applying the shifting and stretching property to the graph of the parent function.

Here the parent function is y=secx\\

As we know,

f(x-c) \ \text{Shift the function by  c units to the right}.\\

So the parent function y=secx\\ gets shifted to right by 5 units.

\text{The graph of the function a*f(x) gets stretched/squeezed by the factor of a }\\ \\ here  \ \ a=2.5>1\\ \\ \text{Hence the parent function will gets squeezed by 2.5} \\

The required plot of the function and parent function is attached.

The correct option has also been attached.

An urn contains 7 red marbles and 3 white marbles. three marbles are drawn from the urn one after the other. find the probabilit
vaieri [72.5K]

7+3 = 10 total marbles

 1st pick = 7/10 for a red one

2nd pick = 6/9 reduces to 2/3 for a red one

3rd pick = 3/8 for a white one

7/10 x 2/3 =14/30 reduces to 7/15

7/15 x 3/8 = 21/120 reduces to 7/40

 probability = 7/40

(1/12)^-2b•12^-2b+2=12?
Anvisha [2.4K]

Step-by-step explanation:

(1/12)^-2b x 12^-2b+2=12

12^-(-2b) x 12^-2b+2=12

12^2b+(-2b+12)=12

2b-2b+12=12

=1

Use the law of Sines to find the missing angle of the triangle. <br> Find m
Whitepunk [10]
Ah...Trigonometry is fun!

The law of sines states:
\frac{sinA}{a}= \frac{sinB}{b} = \frac{sinC}{c}
The transitive property (switching the orders of the equations) applies here. Therfore, we can say that \frac{sinA}{a}=\frac{sinC}{c}

We then plug in our given values to find C

\frac{sin24}{77}=\frac{sinC}{162}
\frac{162*sin24}{77}=sinC
Solving, we get 0.8557316387. We're not done yet!

We are trying to find an angle measure, so we'll do the inverse of the ratio we used (sin).

arcsin0.8557316387 (arcsin is the same as inverse sin)
=58.8 (approximate)

So the measure of angle C is 58.8. You could check this by reinserting it into the equation \frac{sinA}{a}= \frac{sinB}{b} = \frac{sinC}{c}.
