The truth is when V increases, W tends to increase. Positive correlation between two variables in which both variables move in tandem. Positive correlation exists when one variable decreases as the other also decreases or one variable increases while others increase too.
Area of a circle: π x r x r
area of the rectangle = 13x6=78
area of unshaded semi circle (circle) =
π x 3 x 3 = 28.274 ≈ 28.27
78-28.27=49.73 (in 2 decimal place)
if it’s not in 2 decimal place then it’s 49.726
Answer:
$480 total or 80$ in interest
Step-by-step explanation:
5 percent of 400 is 20
20 x 4 = 80
400+ 80= 480
he will make $480 after 4 years
The trains are 275 km apart when both are at their first stop
<em><u>Solution:</u></em>
The tracks make an angle of 130°, with the station as a vertex
Therefore, from given figure in question,
Angle at station = 130 degree
Let "c" be the point at station
The first train travels 100 km and makes its first stop at point A
Distance between A and station c = 100 km
Let a = 100 km
The second train travels 200 km and makes it first stop at point B
Distance between B and station c = 200 km
Let b = 200 km
We have to find the value of "d"
We can use the law of cosine
The square of a side of a plane triangle equals the sum of the squares of the remaining sides minus twice the product of those sides and the cosine of the angle between them.
From given figure in question,
Side opposite "d" to 130 degree is equal to sum of square of other sides a and b minus twice the product of those sides and the cosine of the angle between them which is 130 degrees
Therefore,
Thus trains are 275 km apart when both are at their first stop
Answer:
(a)
(b)
(c)
Step-by-step explanation:
Formula of compound interest:
Compound continuously
A= Amount after t years
P= Principal
r= rate of interest
a)
P=10,000, r=5.5%= 0.055 and t= 5 years, n=2 [ compounded semiannually]
(b)
P=10,000, r=5.5%= 0.055 and t= 5 years, n=12 [ compounded monthly]
(C)
P=10,000, r=5.5%= 0.055 and t= 5 years
