Answer:
Student A says this estimate is reasonable because… Get ... Student A says this estimate is reasonable because the product is negative and about half of 1.5. Student B says you could find the product using a calculator as follows: "Divide −18 by 35, multiply the quotient by 1.43, then round the product
Step-by-step explanation:
calculations with a calculator or computer we need a way of checking that the answers it ... introduce students to this way of thinking and give them practice at estimating simple ... Do they always get the right answer no matter what? Invent a story illustrating a calculator error that you may have made or use the following.
Answer:
An equation of a line that passes through the point (4,3) and is perpendicular to the graph of the equation will be:
Step-by-step explanation:
We know that the slope-intercept form of the line equation is
where
Given the line
y = -13x+4
comparing with the slope-intercept form of the line equation
The slope of the line = m = -13
We know that a line perpendicular to another line contains a slope that is the negative reciprocal of the slope of the other line, such as:
slope = m = -13
Thus, the slope of the the new perpendicular line = – 1/m = -1/-13 = 1/13
Using the point-slope form of the line equation
where
- m is the slope of the line
substituting the values of the slope m = 1/13 and the point (4, 3)
Add 3 to both sides
Therefore, an equation of a line that passes through the point (4,3) and is perpendicular to the graph of the equation will be:
Answer:

Step-by-step explanation:
The loss totalled 1,583,684 over 490 days, so was
... $1,583,684/(490 days) = $3232.01 / day
The average loss per day was $3232.01.
