A whole number has a denominator of 1
Answer:
Step-by-step explanation:
cos(46°) = 24/x
x = 24/cos(46°)
First: markup rate × wholesale price = amount of markup
Second: Well the markup rate is a percentage, you have to convert it into a decimal. Percent means "out of one hundred," so <span>80%</span> is equivalent to <span>80/100 </span>which is also equal to <span>80÷100</span>.
<span>Third: 80÷100=0.80</span>
0.80 × $93.00 = $74.40
Fourth: The markup rate is a percentage of the wholesale price that is added to get the retail price, you can find the retail price with the following equation: amount of markup + wholesale price = retail price
<span>$74.40</span> + <span>$93.00</span> = <span>$167.40</span>
The retail price of the chair should be <span>$167.40</span>.
First lets distribute the 5x
5x^2 + 30x = -50
Lets divide every term by 5
x^2 + 6x = -10
To complete the square we have to half the b value, which in this case is 6. Then square it.
Half of 6 is 3, 3 squared is 9
Add that to both sides of the equation
x^2 + 6x + 9 = -1
Find the binomial squared
(x+3)^2 (If you're wondering how i got that please comment)
(x+3)^2 = -1
Take the square root of the equation of both sides
(x+3) = +/- i
x = -3 +/- i
x = -3 - i
and
x = -3 + i
