Step-by-step explanation:
<h3>Part A</h3>
<u>Multiply the energy produced in 1 second by the number of seconds:</u>
erg
<h3>Part B</h3>
10⁻³ is same as 0.001 times and 10³ is same as 1000 times.
1.6*1000 = 1600 mm = 160 cm = 1.6 m is way too big for the measurement of the distance between the tracks on a CD.
So the first option is correct.
Y divided by x or 500 divided by 25
A point has no dimension. It is usually represented by a dot. A line has one dimension. It is usually represented by a straight line with two arrowheads to indicate that the line extends without end in two directions.
By this equation: d = 4(32), we know what d equals, which means we have the value of d.
d= 4*32
d = 128
Slopes of perpendicular lines are opposite reciprocals of each other. The slope of the given equation (which is in slope-intercept form) is 1, the invisible coefficient of x. The opposite reciprocal of 1 is -1, thus the slope of a line perpendicular to the line y = x + 4 is -1.
Hope this helps.
