Choose the function whose graph is given by:

katen-ka-za [31]

Answer:

D. $y=\tan (x-\pi)+2$

Step-by-step explanation:

We are given the graph of the transformed tangent function.

As, we can see that the graph is shifted 2 units upwards.

That is, the parent function is translated 2 units up.

So, the new function will be of the form, $y=\tan (x)+2$ .

Thus, options A and C are not correct.

Moreover, 'If a function f(x) has period P, then the function cf(bx) will have period $\frac{P}{|b|}$ .

Also, form the figure, we see that the period of the graphed function is $\pi$ .

Since, $y=\tan (x)$ have period $\pi$ .

So, function in option B will have period $\frac{\pi}{2}$ , which is not possible.

<em>Further, function in option D have period $\pi$ .</em>

Thus, the equation of the graphed function is, $y=\tan (x-\pi)+2$ .

Find the measure of the smaller angle formed by hands of a clock at the following time.

goldfiish [28.3K]

A clock is a circle which is 360 degrees.

There are 12 hours -----> 360/12 = 30 degrees.

Going clockwise, add 30 degrees for every hour the hour hand is at.

There are 60 minutes -----> 360/60 = 6 degrees.

Add 6 degrees for every minute the minute hand is at.

Find position of both hour hand and minute hand, then take the difference.

Time is 5:15.
Hour hand is at 5 plus 15/60 or 5.25.
Multiply by 30. 30*5.25 = 157.5

Minute hand is at 15.
Multiply by 6. 15*6 = 90

157.5 - 90 = 67.5 degrees.

Paper 3 Foundation Practice Questions. Monday 13th June 2022

All you have to do is divide the number by the denominator which is 8. So 510 divided by 8.

Which will give you 63.75.

Then you times it by the numerator which is 3 so 63.75 x 3

And you are left with £191.25 which is 3/8 of 510

Use the equation below to find y, if m=7, x=6, and b=2.<br> y=mx+b

Dahasolnce [82]

Answer:

y=44

Step-by-step explanation:

y=mx+b you do substition and replace m with 7 and b with 2 and x with 6

y=7*6+2

the solve with system of order 7 times 6 which is 42 then add the 2 and then you get 44
