In a right triangle, angle C measures 40°. The hypotenuse of the triangle is 10 inches long. What is the approximate length of t

Zepler [3.9K]

Answer:

<em>Approximate length of the side adjacent to ∠C is </em><em>7.66 inches.</em>

Step-by-step explanation:

*The appropriate triangle is attached below.

From the diagram, the right triangle ABC has

Hypotenuse = $\overline{AC}=10\ inch$
$m\angle C=40^{\circ}$

The side adjacent to angle C is BC. We can get the length of BC by applying trigonometric operations.

We know that,

$\cos \theta =\dfrac{b}{h}$

Putting the values,

$\Rightarrow \cos 40 =\dfrac{BC}{10}$

$\Rightarrow BC=\cos 40 \times {10}$

$\Rightarrow BC=7.66\ in$

The graph of an exponential function passes through the point (0,15) and (1,10). What is the equation of the exponential functio

Vilka [71]

Answer:

$y=15(\frac{2}{3})^x$

Step-by-step explanation:

we know that

The equation of a exponential function is of the form

$y=a(b^x)$

where

a is the initial value or y-intercept

b is the base of the exponential function

In this problem we have

$a=15$ ----> the y-intercept is given

substitute

$y=15(b^x)$

we have the other ordered pair (1,10)

substitute the value of x and the value of y and solve for b

$10=15(b^1)\\10=15b$

$b=\frac{10}{15}=\frac{2}{3}$

substitute

$y=15(\frac{2}{3})^x$

see the attached figure to better understand the problem

What is the approximate area of a 70 decree sector of a circle with a radius of 8 inches

puteri [66]

The area of the sector will also be 70/360
Sector area = 70/360 • pir^2
= 7/36 • pi • 8^2
A= 112/9 • pi
A= 39.1 inch^2
