23,456
x 86
If we calculate the conventional way,
This gives us 23,456 * (6 + 80)
= (23,456 * 6) + (23,456 * 80)
First, we multiply 23456 by 6, the figures obtained will be 140736 (which is given in the question)
Next, we multiply 23456 by 80, the figures obtained will be 1,876,480
The third option is the correct answer
Answer:
8/9n - 3
Step-by-step explanation:
Answer:
Robert bought 13 colored pencils and 2 pencils
Step-by-step explanation:
13 x 0.60 = 7.8
2 x 0.45 = 0.9
7.8 + 0.9 = 8.70
13 colored pencils are $7.80
2 pencils are $0.9
15 total is $8.70
Answer:
y = - 2x - 4
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
calculate m using the slope formula
m =
with (x₁, y₁ ) = (- 2, 0) and (x₂, y₂ ) = (0, - 4) ← 2 points on the line
m = = = = - 2
the line crosses the y- axis at (0, - 4 ) ⇒ c = - 4
y = - 2x - 4 ← equation of line
Answer:
Where k represent the number of wave and represent the angular frequency with T the period.
For this case we know tha T = 520 nm
And the angular frequency would be given by:
So then the possible anwer for this case would be:
D.) y= sin pi/260 theta
Since is the only option with satisfy the general equation of a wave.
Step-by-step explanation:
Since the sine function can be used to model light waves we can use the following general expression:
Where k represent the number of wave and represent the angular frequency with T the period.
For this case we know tha T = 520 nm
And the angular frequency would be given by:
So then the possible anwer for this case would be:
D.) y= sin pi/260 theta
Since is the only option with satisfy the general equation of a wave.
