What is 15 n-45/5=6 n-9

Mathematics
1 answer:
Leona [35]3 years ago
5 0

Answer:

Step-by-step explanation:

15n - 45/5 = 6n - 9...reduce any fractions

15n - 9 = 6n - 9 ...subtract 6n from both sides

15n -9 - 6n = 6n - 6n - 9...combine terms

9n - 9 = -9....add 9 to both sides

9n - 9 + 9 = -9 + 9...combine terms

9n = 0....divide both sides by 9

n = 0/9 which = 0

an electronics manufacturer has 140 capacitors, and the same number of capacitors is needed for each circuit board made. the man
natka813 [3]
Let x be the number of circuit boards that can be produced and m be the number of capacitors per circuit board
y = mx
140 capacitors allowed the production of 35 boards.
140 = 35x
x = 4
No circuit boards can be made without capacitors so the line's y intercept is 0. No capacitors are used if no circuit boards are to be made so the x intercept is also 0.

Amplitude of 16 units, a period of 5 units, a vertical displacement of 3 units up and a phase shift of 2.5 units left.
allochka39001 [22]

The question is incomplete. The complete question is :

A sine function that has an amplitude of 16 units, a period of 5 units,a vertical displacement of 3 units up and a phase shift of 2.5 units left. Graph this function and show each step.

Solution :

The standard form of the sine function is

y = a sin (bx - c) + d

Here given :

Amplitude, a = 16

Period :   $\frac{2 \pi}{|b|} = 5$

            ⇒ $b = \frac{2\pi}{5}$

Phase shift :  $\frac{c}{b} = 2.5$

                   $\Rightarrow \frac{c}{2 \pi/5}=\frac{5}{2}$

                  ∴ $c = - \pi$

The vertical displacement : d = 3 units up

Now substituting a, b, c and d values in the standard form gives :

$y = 16 \sin \left( \frac{2 \pi}{5}x -(- \pi)\right) + 3$

$y = 16 \sin \left( \frac{2 \pi}{5}x + \pi\right) + 3$

The graph is attached below.
