Answer:
x = 3

Explanation:
Let's first start with the front triangle.
This one is an isosceles right-angled triangle. This means that it has special side lengths of: s , s and s√2 with s√2 being the hypotenuse.
Since we have the hypotenuse = 6√2 units
Therefore, each of the other two sides would be of length = 6 units

Now, let's consider the side triangle.
This one is also a right-angled triangle. This means that special trigonometric functions can be applied.
These functions are:
sin (θ) = opposite / hypotenuse
cos (θ) = adjacent / hypotenuse
tan (θ) = opposite / adjacent

Now, we have:
θ = 60°
adjacent side = x
hypotenuse = 6 units (calculated from the previous step)

Substitute with the givens in the cos function to get the value of x as follows:
cos (60) = x / 6
x = 6 * cos(60)
x = 3 units

Hope this helps :)

Determine the value of n that makes the polynomial a perfect square trinomial. Then factor as the square of a binomial. Express

blsea [12.9K]

Answer:

Step-by-step explanation:

$y^2-11y+n\\=(y-(11/2))^2+n-(11/2)^2$

So in order the trinomial a perfect square we need

$n-(11/2)^2 =0\\n= (11/2)^2\\n=\frac{121}{4}$

When n is equal to this number that we have

$y^2-11y+n = (y- (11/2))^2$

Answer:

option C

Step-by-step explanation:

$5 = \frac{4}{3}(6y + 9)\\\\5 = \frac{4\times6y}{3} +\frac{4 \times 9}{3}\\\\5= 8y + 12$

The table and the plotted data are in the attachment.

Answer and Step-by-step explanation: A line of best fit is the best approximation of the given data. It is used to show the relation of two variables and it can be determined, more accurately, by the Least Square Method.

To use the method, follow the steps:

1) Calculate the mean of the two variables:

$X = \frac{\Sigma x_{i}}{n}$
