D. 8sqrt3

Determine The Value Of X A. 8B. 4C.8sqrt2D. 8sqrt3

Answers

Answer 1

Answer:

The value of x is : [tex]\mathbf{8\sqrt{2}}[/tex]

Option C is correct.

Step-by-step explanation:

We need to find value of x

We are given Perpendicular = 8

Hypotenuse = x

and Ф= 45°

Using trigonometric identity

[tex]sin \theta=\frac{Perpendicular}{Hypotenuse}[/tex]

Putting values and finding x

[tex]sin \theta=\frac{Perpendicular}{Hypotenuse}\\sin \ 45^o=\frac{8}{x}\\\frac{1}{\sqrt{2} }= \frac{8}{x}\\\frac{1}{\sqrt{2} }x=8\\x=8\sqrt{2}[/tex]

So, the value of x is : [tex]\mathbf{8\sqrt{2}}[/tex]

Option C is correct.

The table shows the outputs y, for different inputs ,x

Input x: 3,7,11,15
Output y: 4,6,8,10

Part A: Do the data in this table represent a function? Justify your answer.

Part B: Compare the data in the table with the relation f(x) = 5x-21. Which relation has a greater value when x=11

Part C: Using the relation in part b, what is the value of x if f(x) =99

Answers

Part A: Yes, the data represent a function. The definition of a function is a relation in which no value of x will have two different values of y.

(Every time you plug in 3 as x, you will always get 4 as y; it's ok if you plug in 3 and 5 as x and get the same y, you just can't get two different y's for one x; sorry, it is pretty confusing). None of the numbers in the table repeat, so we can safely say that the relation is a function.

Part B: All we have to do is plug in 11 for x in the function given to find the answer:

In the table, y = 8 when x = 11, but in the function given, y = 34 when x = 11, so the function given is greater.

Part C: To find the answer to C, just plug in 99 for f(x), as it tells you to do:

Why is it essential to know how to solve Exponential equations in order to solve Logarithmic equations? (Make sure to fully explain).

Answers

Answer:

Because you need it for your later life and for your GCSES and if you dont want to fail then you will need it.

Step-by-step explanation:

Given an exponential equation in which a common base cannot be found, solve for the unknown. Apply the logarithm of both sides of the equation. If one of the terms in the equation has base 10, use the common logarithm. If none of the terms in the equation has base 10, use the natural logarithm.

If it takes 10 hours for 9 workers to mow 45 lawns, dividing the 45 lawns by 9 we see that in 10 hours one worker can mow 5 lawns. This means that in one hour, a single worker can mow 5/10=1/2 of a lawn

Answers

Explanation:

720/6 = 120

44 x 120 = 5280

Answer:

$5280

Hope this helps!!!!!

Step-by-step explanation:

Cost of 6 notebooks = 720

Then, cost of 1 notebook = 720/6

Therefore, cost of 44 notebooks = 720/6 x 44

= 120 x 44

= 5,280

Therefore, the cost of 44 notebooks will be 5,280

What is the slope and y intercept for 14X - 7Y = 28

Answers

Answer:

y = 2x - 4 (the slope is 2 or 2/1 and the y-intercept is -4)

Step-by-step explanation:

Subtract 14x from both sides of the equation.

This should get you  -7y = 28 - 14x.

Then you need to divide by -7 on both sides.

y = -4 + 2x is the result

which you can switch around if you like and get y = 2x - 4
