$HEY MATE !!$

Secx = $\frac{25}{24}$

As we know secx = hypotenuse/ perpendicular

And cotx = Base / perpendicular

So now we have to find BASE .

${25}^{2}= {B}^{2}+ {24}^{2}$
625= ${B}^{2}$ + 576
${B}^{2}$ = 625 - 576
${B}^{2}$ = 49

Taking squre root on both sides.

B = 7

Now cotx = 24/ 7

SO YOUR ANSWER IS OPTION . (C)

HOPE YOU LIKED.

If f(x)= x-3/x and g(x)= 5x-3, what is the domain of (f•g)(x)

ad-work [718]

$f(x)=\dfrac{x-3}{x},\ D_f:x\neq0\\\\g(x)=5x-3,\ D_g=\mathbb{R}\\\\(f\cdot g)(x)=f(x)\cdot g(x)\\\\(f\cdot g)(x)=\dfrac{x-3}{x}\cdot(5x-3)=\dfrac{(x-3)(5x-3)}{x}\\\\D_{(f\cdot g)}=D_f$

Answer: The domain of (f•g)(x) is all real numbers except for 0

$D=\mathbb{R}-\{0\}$

Anna does sit-ups to get ready for her first triathlon. When she starts, she does a sit-up every 222 seconds. But, as she gets t

Alexeev081 [22]

Answer:

Choice B) No.

Step-by-step explanation:

When she starts , she does a sit-up every 222 seconds.

But as she gets tired, each sit-up takes longer and longer to do.

It means, each sit-up takes more time than she did at beginning.

So, it is NOT proportional to the time.

If it is proportional, she should take constant number of sit-ups even she get tired.

Lets check the first point (0,6)

3*0+4=4 no good

0+6 =6 good

0^2+6 =6 good

6 * (7/6) ^0 =6 good

Lets check the second point (1,7)

3*1+4= we don't care since it didn't work for (0,6)

1+6 =7

1^2+6 =7

6 * (7/6) ^1 =7

Lets check the third point (2,10)

3x+4= we still don't care

2+6 = 8 no good

2^2+6 =10 good

6 * (7/6) ^2 =6 * 49/36 =49/6 no good

f(x) = x^2 +6

Nostrana [21]

Answer:

$6.72

Step-by-step explanation:

The store is selling lemons at $0.56 each. Each lemon yields about 2 tablespoons of juice.How much will it cost to buy enough lemons to make three 9-inch lemon pies, each requiring half a cup of lemon juice?

1 cup = 16 table spoon of juice

half a cup = 8 table spoon of juice

1 pie require half a cup of lemon juice. so 1 pie requires 8 tablespoon of lemon juice

Each lemon yields about 2 tablespoons of juice

2 times 4 = 8

So 4 lemon needed to make a pie

cost of 1 lemon = 0.56

cost of 4 lemons = $0.56 \cdot 4=2.24$

cost of lemon for making 3 pie= $3 \cdot 2.24=6.72$
