90 < [( n + n + 2 + n + 4) / 2] < 105

90 < (3n + 6) / 2 < 105

3n + 6 > 180 and 3n + 6 < 210

n > 58 , n < 68

58 < n < 68 answer

There is a circle with a center of 0,0 on a coordinate plane. There is one point on the circle's circumference in which the x:y

abruzzese [7]

Answer:

Step-by-step explanation:

Suppose the radius is 1. The parametric equations for the circle are

x = cosθ

y = sinθ

x:y = 3:1

tanθ = ⅓

cosθ = 3/√(1²+3²) = 3/√10

sinθ = 1/√10

The solutions are (3/√10, 1/√10) and (-3/√10, -1/√10).

Graph a right triangle with the two points forming the hypotenuse. Using the sides, find the distance between the two points in

pshichka [43]

Answer:

$d=\sqrt{53}$

Step-by-step explanation:

We need to find the distance between two points i.e. (−5,−1) and (−3,−8).

It can be calculated using distance formula as follows :

$d=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}$

We have, x₁ = -5, x₂ = -3, y₁ = -1 and y₂ = -8

Put all the values,

$d=\sqrt{(-8-(-1))^2+(-3-(-5))^2}\\\\d=\sqrt{49+4}\\\\d=\sqrt{53}$

So, the distance between the points is equal to $\sqrt{53}$

Judd worked 40 hours this week. He worked 7/10 of the hours outside and the rest inside. How many hours did he work outside?

Mnenie [13.5K]

If you would like to know how many hours did Judd work outside, you can calculate this using the following steps:

40 hours
outside: 7/10 of the hours = 7/10 * 40 hours = 7/10 * 40 = 28 hours

Judd worked 28 hours outside.
