Find the value of x and the value of y

marshall27 [118]

Right triangle 30 60 90
short leg = 1/2 hypo = 4√2 / 2 = 2√2
so x = 2√2

long leg = short leg times √3 = 2√2 * √3 = 2√6
so y = 2√6

answer C.
x = 2√2 ; y = 2√6

What multiplies to give you 108 and adds up to give you -31?

meriva

4 x 27 = 108 and 4 + 27 = 31... I don't think there is any pair of numbers that would equal -31. So the answer would be 4 and 27. Good luck! Hope this helped!!

writing an equation of a line given its slope and y-intercept. write an equation in slope-intercept form for the line with slope

Gre4nikov [31]

Answer:

y = -5(x-1)

Step-by-step explanation:

A y-intercept of 1 means that the point (0,1) falls on the line.

Slope-intercept form is $y-y_{1} =m(x-x_{1} )$ where m is the slope...

Therefore, the slope-intercept equation is y-1=-5(x-0) or y-1=-5x

A line in standard (x,y) coordinate plane passes through the points (7.5 ,-4.25) and (12.5,-6) find the slope of the line

Svet_ta [14]

Answer:

Step-by-step explanation:

Rise over run. Difference in y values is rise. 4.25 -6 is -1.75. Run s difference in x values. 12.5 -7 is 5. Divide -1.75/5 to get -0.35 As a faction thats -7/20

The height of a wooden pole, h, is equal to 20 feet. A taut wire is stretched from a point on the ground to the top of the pole.

kykrilka [37]

ANSWER

D. 25 feet

EXPLANATION

The height of the wall,h, the taut wire and the distance from the base of the pole to the point on the ground, formed a right triangle.

According to the Pythagoras Theorem, the sum of the length of the squares of the two shorter legs equals the square of the hypotenuse.

Let the hypotenuse ( the length of the ) taught wire be,l.

Then

${l}^{2} = {h}^{2} + {b}^{2}$
