perpendicular slopes are those that are opposite sign and reciprocal of the original given slope
Answer:
.
Step-by-step explanation:
Notice that the first two factors are in the form 
, which is equal to 
. Start by combining and expanding these two factors:
Let 
.
.
.
This expression can now be expressed as 
. 
stands the unit imaginary number, where 
. Unless is raised to a certain power other than 
, it can be treated just like a constant.
Expand this expression using FOIL:
.
Answer:
The data is quantitative
Data is discrete
The highest level is Ordinal
Step-by-step explanation:
Data is of quantitative type when it allows us to measure, in a numerical and objective way, the differences between different observations. Eventhough the supervisor uses words ( fair, poor etc) he can assign numerical values and measure differences between observations that has sense. Qualitative data refers to opinions, stories, interviews, images or data that cannot be interpreted numerically and has subjective interpretations depending in researcher.
Data is discrete because the variable measured: evaluation rating, can only takes certain specific values (1 to 5) A continuous variable, such as height can take many values in a ratio or real line,
Nominal data refers to variables that takes two possible values - the presence and absence of a characteristic, like being or not being a minor. Ordinal variables are variable which are discrete but the value of the variable allows to classify data in a specific order. This is the case of the rating scale. Interval variables are are ones that have specific low levels and high levels like age ranges.
Answer:
If the actual width is 36 feet, then the tent is 3 inches wide in scale.
Step-by-step explanation:
Let x be the width in inches.
The scale is: 1 inch : 12feet. The scale can be represented as inches to feet ratio and then equivalent ratios will be used
This can be expressed as fraction as 1/12
The equivalent ratios are:
Hence,
If the actual width is 36 feet, then the tent is 3 inches wide in scale.
Answer:
you can use the formula "<em>Cross method" </em> in which the last number of the equation is the sum of 2 number multiplication that also sums the 2nd num of the equation.
so it becomes
(x +6)(x +7)
WHY?
Bcs when u multiply 6 x 7 = 42 ( the last number of the equation)
when u sum 6 + 7 = 13 ( the 2nd number of the equation)
Hope this helps :)
