Answer:

Sine of an angle =

opposite / hypotenuse

I this figure

AB is the opposite which is 12

BC is the hypotenuse which is 13

sine ∅ = 12/13

Therefore the sine ratio of the angle is

12/13

Hope this helps

Use the Pythagorean theorem to find the missing length in the following right triangle.
lesantik [10]
Hello there!


The Pythagorean Theorem is:

a² + b² = c²

We have b = 48 and c = 50

Remember: The hypotenuse is always longer.

a² + 48² = 50²

a² + 2304 = 2500

a² = 2500 - 2304

a² = 196

a = √196

a = 14

The missing length is 14.

Let me know if you have any questions. As always, it is my pleasure to help students like you!

I WILL MAKE YOU THE BRANLIEST
Anuta_ua [19.1K]

The area of a triangle is given by half the multiplication of base and height. Since you want the answer is squared centimeters, let's convert base and height in centimeters first:

b = 4.3 m = 430 cm, \qquad h = 2.6m = 260 cm

Now we can do the computation:

A = \dfrac{430cm \cdot 260cm}{2} = 55900 cm^2

The graph of the function P(x) = −0.34x2 + 12x + 62 is shown. The function models the profits, P, in thousands of dollars for a
STatiana [176]

Answer:

0 ≤ x < 1.12 and 34.18 < x ≤ 39.87

Step-by-step explanation:

<u><em>The options of the question are</em></u>

−4.57 ≤ x ≤ 39.87

1.12 ≤ x ≤ 34.18

−4.57 ≤ x ≤ 1.12 and 34.18 ≤ x ≤ 39.87

0 ≤ x < 1.12 and 34.18 < x ≤ 39.87

Let

x ----> is the number of tires produced, in thousands

C(x) --->  the production cost, in thousands of dollars

we have

C(x)=-0.34x^{2} +12x+62

This is a vertical parabola open downward (the leading coefficient is negative)

The vertex represent a maximum

The graph in the attached figure

we know that

Looking at the graph

For the interval [0,1.12) ----->  0\leq x

The value of C(x) ----> C(x) < 75

That means ----> The production cost is under $75,000

For the interval (34.18,39.87] -----> 34.18 < x\leq 39.87

The value of C(x) ----> C(x) < 75

That means ----> The production cost is under $75,000

Remember that the variable x (number of tires) cannot be a negative number

therefore

If the company wants to keep its production costs under $75,000 a reasonable domain for the constraint x is

0 ≤ x < 1.12 and 34.18 < x ≤ 39.87
