Answer:
x = 216
Step-by-step explanation:
2 + 5 = 32
Subtract 2 from both sides of the equation
i.e. 2 + 5 - 2 = 32 - 2
5 = 30
Take the cube of both sides of the equation
i.e. (5)³ = (30)³
(5)³()³ = (30)³
(5 × 5 × 5)()³ = (30 × 30 ×30)
125x = 27,000
Divide both sides of the equation by the coefficient of x(which is 125)
x = 216
<u>Check</u>
Substituting 216 for x in 2 + 5∛x = 32,
2 + 5 = 32 ( = 6)
2 + (5 × 6) = 32
2 + 30 = 32
∴ x = 216
Hope this helps :))
Answer:
p=$15000
R=15%
t=5years
compound amount CI=?
Step-by-step explanation:
we have
- CI=p(1+R/100)^t=$15000(1+15/100)^5=$15000×1/15^5=$30170.35
Answer:
86
Step-by-step explanation:
because 86 reminds me of 69
If you have learned how to find the line of best fit manually, then you can do it that way. Perhaps you may want to just find a line that can connect at least two of the points and I believe that that line will be able to represent the other points because, in general, the points are pretty close to one another.
If you don't want to do it manually and have a graphing calculator (which I recommend) then you can use that to find the line of best fit (and if you want then you can see how precise your points are with your r^2 value). Or there is a website (http://illuminations.nctm.org/Activity.aspx?id=4186), which you can use to help you to find the equation of that particular line.
Once you have that done, then you can substitute 2009 for the x value in the equation and then see what y value the equation produces. That will then be your answer :)
Answer:
The figure will change by a factor of 2.25.
Step-by-step explanation:
When the lengths (1-dimensional) change by a factor 1.5 (the definition of <em>dilating </em>a figure), the area (2-dimensional) will change by a factor 1.5 to the power of the quotient of the values of the dimensions, which is 2/1 = 2. So the area will change by a factor of 1.5^2 = 2.25.
