Find the value of y. 5 8 4 2 50 Pts!

Vinvika [58]

Answer and Explanation:

Since this is a 30-60-90 triangle, you can use the ratio of side lengths specific to this type of triangle:

x = 4√(2)

y = 2(4) = 8

because where 4 = T,

x = T√2 and y = 2T

so again:

$x = 4\sqrt{2}\\y = 8$

The graph of the function f(x)

Oksi-84 [34.3K]

Step-by-step explanation:

A special relationship where each input has a single output. It is often written as "f(x)" where x is the input value. Example: f(x) = x/2 ("f of x equals x divided by 2") It is a function because each input "x" has a single output "x/2": • f

If the polar coordinates of a point are given by (9.77 m, θ) and the rectangular coordinates are given by (x, 3.50 m), determine

Artyom0805 [142]

Answer:

the solutions are (9,12 m , 0.366 rad) and (-9,12 m , 1.936 rad)

Step-by-step explanation:

given the polar coordinates (r=9.77 m , θ) and (x, y=3.50 m) , since we know that

x²+y²=r² → x = ±√(r²-y²) = ±√(9.77 ²-3.50 ²)= ± 9,12 m

then

x = r* cos θ → for θ = cos ⁻¹ (x/r)

thus

for x= 9,12 m → θ = cos ⁻¹ (9,12 m/9.77 m) = 0.366 rad

for x= -9,12 m → θ = 0.366 rad + π/2 rad = 1.936 rad

therefore the solutions are (9,12 m , 0.366 rad) and (-9,12 m , 1.936 rad)
