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.

Find the common ratio.
statuscvo [17]

Answer:

324, -972, 2916

Step-by-step explanation:

Divide a number by the previous number to find r.

r = -12/4 = -3

Multiply a number by r to find the next number.

-108 * (-3) = 324

324 * (-3) = -972

-972 * (-3) = 2916

Answer: 324, -972, 2916

An engineer is planning a new water pipe installation. The circular pipe has a diameter of d=20\text{ cm}d=20 cmd, equals, 20, s
Alex_Xolod [135]

Answer:

314.2 cm²

Step-by-step explanation:

The area of the circular cross section of the pipe is given by A = πd²/4 where d = diameter of pipe = 20 cm

So, A = πd²/4

substituting the value of d into the equation, we have

A = π(20 cm)²/4

A = π400 cm²/4

A = 100π cm²

A = 314.16 cm²

A ≅ 314.2 cm²
