3x-9 when x=3 Solve this

Mathematics
1 answer:
Citrus2011 [14]3 years ago
3 0

Answer:

0

Step-by-step explanation:

3x - 9 if x = 3

Substitute:

3(3) - 9 =

9 - 9 = 0

This can be written as a function: f(x) = 3x - 9

f(3) = 3x - 9

f(3) = 3(3) - 9

f(3) = 9 - 9

f(3) = 0

Find a function ω(x) such that the function f(x) = sin(ω(x)) has the roots at π, π2
atroni [7]

So, I came up with something like this. I didn't find the final equation algebraically, but simply "figured it out". And I'm not sure how much "correct" this solution is, but it seems to work.

f(x)=\sin(\omega(x))\\\\f(\pi^n)=\sin(\omega(\pi^n))=0, n\in\mathbb{N}\\\\\\\sin x=0 \implies x=k\pi,k\in\mathbb{Z}\\\Downarrow\\\omega(\pi^n)=k\pi\\\\\boxed{\omega(x)=k\sqrt[\log_{\pi} x]{x},k\in\mathbb{Z}}

Solve-2a - 5 &gt; 3.<br> Which graph shows the solutions?
stellarik [79]
The last number line the correct answer!
-2a-5>3
-2a>8
a<-4

( the sign is flipped in the end because when you multiply or divide by a negative number, the sign flips the other way around)

A helicopter is hovering above a road at an altitude of 24 m. At a certain time, the distance
LuckyWell [14K]

Answer: 32.23°

Suppose the setpoint of a helicopter is A and that of a car is C and that of the road is B

The distance from the helicopter to the car and the road forms a right triangle

=> ΔABC is a right triangle at B

=> the angle of depression from  the helicopter from the car is ∠ACB

we have: ΔABC is a right triangle => sin ∠ACB = 24/45

=> m∠ACB = 32.23°

Explain how to rewrite the equation -2x - 6y = 18 in slope-intercept form.
MrMuchimi

Answer:

y = -1/3x -3

Step-by-step explanation:

-2x - 6y = 18

We want to solve for y since the slope intercept form is y =mx+b where m is the slope and b is the y intercept

Add 2x to each side

-2x-6y +2x = 2x+18

-6y = 2x+18

Divide each side by -6

-6y/-6 = 2x/-6 + 18/-6

y = -1/3x -3

This is in slope intercept form with the slope -1/3 and the y intercept -3
