To calculate the area of triangle with three sides we use Heron's formula,
Area=sqrt(s(s-a)(s-b)(s-c))
where:
s=(a+b+c)/2
thus,
s=(15+10+20)/2
=22.5
hence the area will be:
Area=sqrt(22.5(22.5-15)(22.5-10)(22.5-20))
Area=sqrt(22.5*7.5*12.5*2.5)
=sqrt5273.4375
=72.62 mm^2
The median of a data set is the number that is the middle value.
First you have to rearrange the numbers from greatest to least.
If there are any odd numbers then the median is in the center term.
If there is an even number of terms, you add the two middle terms and divide them by 2.
Answer:
B. -4
Step-by-step explanation:
The function only has one y-value: -4. That is the entirety of its range.
Answer: account b
Step-by-step explanation:
account A will give 92 thousand dollars
account B will give 100 thousand dollars
I put it in a table
To answer this, you would represent this as 5000x2x2x2x2x2x2x2x2x2x2. By writing this expression, you are representing the doubling for every year. The easiest way to show this would be to use exponents though. Two multiplied by itself 10 times is the same thing as saying two to the 10th power. So 5000 x 2^10. This is the answer, I think choice B was meant to say that.
