The diagnoal of a tv is 26 inches long . assuming that this diagonal forms a pair of 30 -60 - 90 right triangles , what are the exact length and width of the tv?

Answers

Answer 1

Answer: 13 inches by 13-√3 inches

Let

x-------> the length side of the TV

y-------> the width of the TV

d------> the diagonal of a TV

we know that

in a 30-60-90 right triangle
cos (30°) = √³/2

sin (30°) =1/2

d = 26 in

sin (30°) = ----> y = d * sin(30°)

cos (30°) = ----> x = d * cos (30°)

substitute the values

y = 26* = 13 in

x = 26³ = 13√√3 in

the length side of the TV is 13√3 in the width of the TV is 13 in

Answer: 13 inches by 13-√3 inches

I hope this helps! :)

Find two positive numbers whose product is 192 and their sum is a minimum.

Answers

Answer:

8√3

Step-by-step explanation:

Let a, b = the positive numbers, and the sum = s,

(1)---- ab = 192

(2)--- a + b = s

Since we want to find the minimum sum, we'll have to substitute one of the variables (either a or b) from (1) to (2), I'll choose b,

From (1), b = 192/a

Substitute b = 192/a into (2),

s = a + 192/a

Now, we are able to use a concept of calculus (maximum & minimum) to solve it, just remember 2 steps in finding the values of x in maxima minima question:

1) find dy/dx

2) Find x from dy/dx = 0

ds/da = 1 - 192/

When ds/da = 0,

1 - 192/ = 0

= 192

a = ±192

a = 83 , -83

Since a is positive, a = 83

Substitute a into (1),

b = 192/(83)

b = 83

Therefore, the two positive numbers are 8√3... and 8√3

Find the equation of a line passing through the same point that f(x) passes through at x = 3 with a slope equal to the
limit you found in part A.

Answers

the equation of the line f(x) slope 3

The function is f(x) = x³ − 4x² + 2.

How to find the slope?

The slope of a line or straight object is the ratio of how much amount of rise occurs in correspondence to the increment in the run.

Find the difference between the y coordinates, Δy is change in y.Find the difference between the x coordinates, Δx is change in x.Divide Δy by Δx to find slope.

As,

Slope = rise/ run

Given:.

f(x) = x³ − 4x² + 2

As a line passing through the same point that f(x) passes through at x = 3 with a slope equal to the limit.

Then the slope of the function is given by the differentiation.

slope= d/dx [f(x)]

slope= d/dx  ( x³ − 4x² + 2)

slope=  3x² - 8x

slope= 3* 3* 3 -8*3

slope= 27-24

slope= 3

An exponential function is a mathematical function in the form y = ab^x

This can be simplified as:

2.) 7

3.) 167 students/year

4.) 1879

5.) 1879+167t

6.) 4050

Step-by-step explanation:

1.) Find the difference between the number of students in 2002 and 2009:

[tex]3382-2213=1169[/tex]

2.) Find the difference in the years:

[tex]2009-2002=7[/tex]

3.) To find the average growth, find the change between 2002 and 2009 and divide by 7.

[tex](3382-2213)/7=y\\1169/7=y\\167=y[/tex]

4.) To find the population of the students in the year 2000, we need to subtract the average growth time and the difference of years from 2213.

[tex]2213-167(2002-2000) = y\\2213-334=1879[/tex]

5.) Taking the equation above, and changing it to match the requirements, we get:

[tex]P = 1879+167t[/tex]

6.) Now find the difference between 2013 and 2000, and substitute for t to get:

[tex]P = 1879+167(2013-2000)\\P = 1879+167*13\\P = 4050[/tex]
