Suppose PQ has one endpoint at

Mathematics
1 answer:
klio [65]2 years ago
5 0

Step-by-step explanation:

The midpoint can be found with the formula.

midpoint = (x1+x2) /2 , (y1 + y2 )/2

 ( x1 , y1), and (x2 , y2 ) are the coordinates of two points, and the midpoint is a point lying equidistant and between these two points.

P = (0,0)

midpoint = (2,5)

x midpoint = 2 = (0+ x2)/2

×2 = 4

y midpoint = 5 = (y2+0 )/2

10 = y2

so the point Q is (4 , 10)

If sine of x equals square root of 2 over 2, what is cos(x) and tan(x)? Explain your steps in complete sentences.
kolbaska11 [484]
Sin x =  square root (2) / 2

In order for us to get for cos x and tan x, first we need to know what 
Hypotenuse, Adjacent, and Opposite sides.

sin x = opposite / hypotenuse.

adjacent = square root (hypotenuse^2 - opposite^2)
adjacent = square root (2^2 - square root(2)^2)
adjacent = square root (4 - 2)
adjacent = square root (2)

cos x = adjacent / hypotenuse
tan x = opposite / adjacent..

cos x = square root (2) / 2
tan x = square root (2) / <span>square root (2)  = 1

So, </span>cos x = square root (2) / 2 and tan x<span> = 1</span>

Shawn drew a rectangle that had a width of 4.2 inches and a length of 8.1 inches. Find the perimeter of Shawn's rectangle
MArishka [77]

Answer: 24.6 inches


Step-by-step explanation: Since it's a rectangle, and not a rectangular prism, that means it's 2D. Length is the long sides on the top and bottom, and width is the shorter sides on it's left and right. So since there's two of each, just do 8.1 + 8.1 + 4.2 + 4.2 and you have your answer!

F(x) = 2x^2 – 5x; find f(3)​
Nookie1986 [14]

Answer:

f(3) = 3

Step-by-step explanation:

f(x) = 2x^2 – 5x

Let x = 3

f(3) = 2(3)^2 - 5(3)

      = 2*9 -15

      = 18-15

      =3
