Distance between two points =
√(3−−2)2+(3−3)2= √52+02= √25+0=
√25= 5
Distance between points (-2, 3) and (3, 3) is 5
Im assuming the base of the triangle is 4cm. The volume is
.
If the dimensions are tripled, the base is 12, the height is 24, and the length is 18. The volume is
, which is 27 times bigger.
If you are increasing each side by a factor of x, you are multiplying the original by
Answer:
see the explanation
Step-by-step explanation:
we have
0.888...
This is a <u>repeating decimal</u> (Is a decimal that has a digit, or a block of digits, that repeat over and over and over again without ever ending)
Convert to fraction number
Let
x=0.888...
10x=8.888...
Subtract 0.888... from 8.888... to remove the decimal
10x-x=8.888...-0.888...
9x=8
Solve for x
x=8/9
therefore
Mike fraction is incorrect
because 4/5=0.8
0.8 is a <u>terminating decimal </u>(It's a decimal with a finite number of digits)
Mike's mistake was considering the number as a terminating decimal instead of a repeating decimal
Beth is correct
because
If you divide 8/9
the result is 0.8888888...
<span>cost of producing x radios is c(x) = 400 + 20x - 0.2x
where:
x=number of units
thus the cost required to produce 30 units will be given by
c(30)=400+20(30)-0.2(30)
c(30)=400+600-6
c(30)=994
Answer: Marginal cost will be $994</span>
