Step-by-step explanation:
Uhm, 2 miles every 2/5 hours? :joy:
It says "Laura jogs at a unit rate of 2 miles every 2/5 hours"
and then says "What is her unit rate"
Sooooo LoL
Formula for Riemann Sum is:
interval is [1,3] so a = 1, b = 3
f(x) = 3x , sub into Riemann sum
Continue by simplifying using properties of summations.
Now you have an expression for the summation in terms of 'n'.
Next, take the limit as n-> infinity.
The limit of
goes to 0, therefore the limit of the summation is 12.
The area under the curve from [1,3] is equal to limit of summation which is 12.
It should be D, if -7x-2 is 14, then -5x-2 will be 10.
Answer:
x=-7
Step-by-step explanation:
-8x = 56
divide both sides by -8
that leaves you with x = -7
you can plug it in to check because -8 * -7 = 56
Answer:
Conversion and substitution
Step-by-step explanation:
One way to find out if the expression is true, we can convert all the percentages into their decimal equivalence.
60% = 0.6
10% = 0.1
6% = 0.06
Now let's substitute the values.
0.06 = 0.6 x 0.1
0.06 = 0.06
Since 0.06 is equal 0.06, this then proves that it is true.
