Please help with number 8. And if you can explain how you got the answer please do and I’ll give brainliest

ddd [48]

Answer:

X=7.9

Y=7.9

Step-by-step explanation:

We have that x=y

And form Pythagoras theorem we have

$5 \sqrt{5} = \sqrt{x ^{2} + x ^{2} } \\ take \: the \: square \: of \: the \: two \: sides \\ 125 = 2x ^{2} \\ x {}^{2} = 62.5 \\ x = 7.9$

So x = y = 7.9

On a coordinate plane, a line is drawn from point A to point B. Point A is at (2, negative 3) and point B is at (negative 4, 9).

zimovet [89]

Answer: (0,1)

Step-by-step explanation:

If $(x_1, y_1)$ and $(x_2, y_2)$ are two point son a coordinate plane and (x,y) dividing it in a ratio of m: n.

Then , the coordinates of (x,y) is given by :-

$x=\dfrac{nx_1+mx_2}{m+n}$

$y=\dfrac{ny_1+my_2}{m+n}$

Given : On a coordinate plane, a line is drawn from point A to point B. Point A is at (2, - 3) and point B is at (- 4, 9).

Then , the x- and y- coordinates of point E, which partitions the directed line segment from A to B into a ratio of 1:2 :

$x=\dfrac{2(2)+1(-4)}{1+2}=0$

$y=\dfrac{2(-3)+1(9)}{1+2=1}$

Hence, the x- and y- coordinates of point E = (0,1)

If sin 0 = 7/25, find csc 0

kipiarov [429]

Answer:

$csc(\theta)=\frac{25}{7}$

Step-by-step explanation:

We know that:

$sin(\theta)=\frac{7}{25}$

And we want to find:

$csc(\theta)$

Remember that there is a trigonometric identity that relates the $sin(\theta)$ function with the $csc(\theta)$ function

$csc(\theta)=\frac{1}{sin(\theta)}$

Then if $sin(\theta)=\frac{7}{25}$ this means that:

$csc(\theta)=\frac{1}{\frac{7}{25}}$

Finally:

$csc(\theta)=\frac{25}{7}$
