Using trigonometric ratios, tan a + cot a = (cos a + sin a) / sin a * cos a

<h3>Trigonometric Ratio</h3>

The six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec). In geometry, trigonometry is a branch of mathematics that deals with the sides and angles of a right-angled triangle. Therefore, trigonometric ratios are evaluated with respect to sides and angles.

In the question given, the trig ratio is

tan a + cot a

We can simplify this as

tan a = sin a / cos a

cot a = 1 / tan a = 1 / sin a / cos a = cos a / sin a

Adding both ratios together

tan a + cot a = (sin a / cos a) + (cos a / sin a)

tan a + cot a = (cos a + sin a) / sin a * cos a

A company needs 713 slices of pizza for a company party. If each pizza is cut into 8 slices, about how many whole pizzas should

alukav5142 [94]

Answer:

Step-by-step explanation:

To find the number of WHOLE pizzas needed, we need to divide the total number of slices needed (713) by 8 slices. Thus

$\frac{713}{8}=89.125$

<em>because we can't order fractional pizza, we need to round up. So we will need 90 pizzas.</em>

<em>Correct answer is D.</em>

To solve this problem, we will use the formula for permutation. A permutation is where the order of the things in the set matter.
Solution:
₁₂P₅ = $\frac{12!}{7!}$ = 12 x 11 x 10 x 9 x 8 = 96,040 different ways that can be made.

You deposit $400 in an account. The account earns $18 simple interest in 9 months. What is the annual interest rate

Mamont248 [21]

Use the formula,

I = Prt

P = Principal amount = 400

I = interest = 18

r = annual rate

t = time in years = 9/12 = 3/4

so,

18 = 400*r*3/4

r = 0.06

so the annual interest rate is 0.06 or 6%.

Find the area of this trapezoid. Be sure to include the correct unit in your answer. Continue 13 cm 20 cm 8 cm 5 cm 0 0/0 08 cm

kodGreya [7K]

Given:

• Upper Base of trapezoid = 8 cm

• Lower base = 20 cm

• Length of one leg (also height) = 5 cm

• Length of other leg = 13 cm

Let's find the area of the trapezoid.

To find the area of the trapezoid, apply the formula:

$A=\frac{a+b}{2}*h$

Where:

A is the area

a is the length of upper base = 8 cm

b is the length of the lower base = 20 cm

h is the height = 5 cm

Plug in the values for a, b, and h to find the area, A:

$\begin{gathered} A=\frac{8+20}{2}*5 \\ \\ A=\frac{28}{2}*5 \\ \\ A=14*5 \\ \\ A=70\text{ cm}^2 \end{gathered}$

Therefore, the area of the trapezoid is 70 cm^2
