Answer:

  see below for a graph

Step-by-step explanation:

Completing the square for x and y terms can help you put this in the standard form.

  (x^2 +10x) +(y^2 +6y) = -18

  (x^2 +10x +25) +(y^2 +6x +9) = -18 +25 +9 . . . . add square of half linear coefficient

  (x +5)^2 +(y +3)^2 = 16 . . . . . . . circle centered at (-5, -3) with radius 4

Look at the figure below: an image of a right triangle is shown with an angle labeled y If sin y° = 7 divided by q and tan y° =
Andre45 [30]

Answer:

Cosy° = \frac{r}{q}

Step-by-step explanation:

From the picture attached,

By applying all trigonometric ratios in the given right triangle,

Siny° = \frac{7}{q} = \frac{\text{Opposite side}}{\text{Hypotenuse}}

tany° = \frac{7}{r} = \frac{\text{Opposite side}}{\text{Adjacent side}}

Therefore, Cosy° = \frac{\text{Adjacent side}}{\text{Hypotenuse}}

Cosy° = \frac{r}{q}

Therefore, Cosy° = \frac{r}{q} will be the answer.

A sign in front of a roller coaster says "You must be 40 inches tall to ride." What percentage of this height is
insens350 [35]

Answer: he percentage of height of A is 85% and the percentage of height of B is 135% and it can be evaluated by using unitary method.

Step-by-step explanation:

he percentage of height of A is 85% and the percentage of height of B is 135% and it can be evaluated by using unitary method.

Given :

To ride on roller coaster you must be 40 inches tall.

Unitary method is used to find the percentage of height of A and percentage of height of B. Single unit is determined first in the unitary method and than multiply the single unit to find the necessary value.

Applying unitary method to determined the percentage of height of A.

Divide 34 by 40.

       

Multiply the above value by 100.

       

       = 85%

Again applying unitary method to determined the percentage of height of B.

Divide 54 by 40.

       

Multiply the above value by 100.

       

       = 135%

The percentage of height of A is 85% and the percentage of height of B is 135% and it can be evaluated by using unitary method.
