What is the value of the sin3x/6x; as x approaches to zero
Answers
Step-by-step explanation:
When x = 0,
sin3x / 6x = 0 / 0, which is an indeterminate form.
Hence we use L'Hospital's rule:
d/dx (sin3x) = 3cos3x
d/dx (6x) = 6
Now we have 3cos3x / 6 or 0.5cos3x.
When x = 0, 0.5cos3x = 0.5(1) = 0.5.
Hence the limit is 0.5.
Using limits, it is found that the value of the function is of 0.5.
The limit given is:
[tex]\lim_{x \rightarrow 0} \frac{\sin{(3x)}}{6x}[/tex]
The following property is used:
[tex]\lim_{x \rightarrow 0} \frac{\sin{(ax)}}{ax} = 1[/tex]
Hence, multiplying the numerator and denominator by 0.5:
[tex]\lim_{x \rightarrow 0} \frac{\sin{(3x)}}{6x} = 0.5\lim_{x \rightarrow 0} \frac{\sin{(3x)}}{3x} = 0.5(1) = 0.5[/tex]
The value of the function is of 0.5.

What is 9m + 6 = 87
please help im desperate fwhe
Answers
Answer:
m=9
Step-by-step explanation:
9m=81
Answer:
9
Step-by-step explanation:
First you have to get the variable by its self (m). So you will get rid of 6 and since it’s positive you will do negative 6 to cancel it out. But what you do to one side you do to the other, so you will do 87 - 6 and get 81. Now it’s 9m = 81. So then since 9 is next to m that implies multiplcation so you do the opposite of multiplication and dived 9 by both sides. And when you do that you get 9.

A tv has a screen that is 15 in long and has a 25 in long diagonal find the area of the tv screen?
Answers
Answer:
300 in²
Step-by-step explanation:
The TV screen is rectangular in shape.
Thus:
Length of the rectangular screen = 15 in.
Diagonal of the rectangular screen = 25 in.
To find the area of the rectangular screen, we need the length and the width of the screen.
Use pythagorean theorem to find the width as shown below:
[tex] a^2 + b^2 = c^2 [/tex], where:
a = width = ?
b = 15 in.
c = 25 in. (The hypotenuse/longest side)
Plug in the values into the equation
[tex] a^2 + 225 = 625 [/tex]
Subtract 225 from each side
[tex] a^2 = 400 [/tex]
Take the square root of both sides
[tex] a = 20 [/tex]
width of the screen = 20 in.
Thus,
Area of the screen = length × width
= 15 × 20
Area = 300 in²
