Answer:

$2089

Step-by-step explanation:

One way to do this rounding is to add $0.50, then drop all of the fractional digits.

$2088.523125 + 0.50 = $2089.023125

Dropping all of the digits right of the decimal point gives $2089.

A contractor purchases 6 dozen pairs of padded work gloves for $87.12. She incorrectly calculates the unit price as $14.52 pe

artcher [175]

So, there are 6 dozen pairs of gloves. That amount of gloves costed $87.12. She calculated the amount per pair as 14.52. This was incorrect because she forgot about the majority of the 6 dozen(one dozen is the number 12). So that means there are not 6 pairs of gloves, in fact, there are 72 pairs of gloves. So, now that we have that number, we can correctly calculate the amount of gloves per pair. Now we have 2 answers. The amount per glove and the amount per pair

Answer 1: Each pair of gloves costs $1.21.

Answer 2: Each individual glove costs 61¢(if there is a number under the hundredths place in the price, like in the thousandths, you always round upwards, in this case, the cost was .605, but you round up, making it 61¢)

Provide me three coordinate points for the following, given the Slope and Y-intercept. 5. Slope = 7/9, Y intercept = 12(give me

madam [21]

Since we have that the slope is m = 7/9 and the y-intercept is b = 12, we can write the equation of the line in slope-intercept form:

$\begin{gathered} y=mx+b \\ \Rightarrow y=\frac{7}{9}x+12 \end{gathered}$

to find three coordinate points, we can use arbitrary values on x to get the y-coordinate. To make things easier, let's use x = 9, 18 and 27:

$\begin{gathered} x=9 \\ \Rightarrow y=\frac{7}{9}(9)+12=7+12=19 \\ x=18 \\ \Rightarrow y=\frac{7}{9}(18)+12=7(2)+12=14+12=26 \\ x=27 \\ \Rightarrow y=\frac{7}{9}(27)+12=7(3)+12=21+12=33 \end{gathered}$

therefore, the line with slope m = 7/9 and y-intercept 12 passes through the three points (9,19), (18,26) and (27,33)

Let f(x)=x2−2x−4 . What is the average rate of change for the quadratic function from x=−1 to x = 4?

goblinko [34]

Answer:

The average rate of change for f(x) from x=−1 to x = 4 is, 1

Step-by-step explanation:

Average rate A(x) of change for a function f(x) over [a, b] is given by:

$A(x) = \frac{f(b)-f(a)}{b-a}$
