Answer: 42.14 cm^2
square:
Area of a square=s^2
A=14^2
A=196
circle (the two semi circles are the same as one circle):
Area of a circle=(pi)(r)^2
divide 14 (diameter) by 2 to find the radius
A=(3.14)(7)^2
A=(3.14)(49)
A=153.86
subtract the area of the two semi circles from the area of the square to get the answer
196-153.86=42.14
<h2>
Coordinate Pairs</h2>
Coordinate pairs are organized like (x,y).
- x tells us the location of the point in relation to the x-axis, the axis that is horizontal.
- y tells us the location of the point in relation to the y-axis, the axis that is vertical.
To determine a coordinate pair, we can determine each coordinate individually, then put them together.
<h2>Solving the Question</h2>
Notice how the red point sits on the very edge of the graph.
When we look at the x-axis, we can see that it occurs at the number 0 on the x-axis. In other words, the red point occurs when x=0.
When we look at the y-axis, we can see that it lines up with the number 2. In other words, the red point occurs when y=2.
Therefore, when we put the two coordinates together like (x,y), we get (0,2).
<h2>Answer</h2>
(0,2)
Answer:
11.4 years
Step-by-step explanation:
We assume you want to know the time it takes for Lucy's investment of $1200 to have a value of $6400. The compound interest formula is good for finding that.
FV = P(1 +r/n)^(nt)
for principal P invested at rate r per year for t years, compounded n times per year. We want to find t such that ...
6400 = 1200(1 +0.15/4)^(4t)
16/3 = 1.0375^(4t) . . . . divide by 1200
log(16/3) = 4t·log(1.0375) . . . . take logarithms
t = log(16/3)/(4·log(1.0375)) ≈ 11.4
It will take about 11.4 years for Lucy's investment value to be $6400.
Answer:
10 units
Step-by-step explanation:
To find the length we can use the formula
d = sqrt( (y2-y1)^2 + (x2-x1)^2)
We have the two points (-5,5) and (3,-1)
d = sqrt( (-1-5)^2 + (3--5)^2)
d = sqrt( (-6)^2 + (3+5)^2)
d = sqrt( (-6)^2 + (8)^2)
d = sqrt( 36 + 64)
d = sqrt(100)
d = 10
The circumference of the circle is 75.36 cm.
Diameter of the circle is 24 cm,
- Step 2: Formula used and calculation:
Circumference of the circle is 
.
So, Radius, r = 24/2 = 12 cm.
Now, Putting the value in the above formula, we get
2 × 3.14 ×12 = 3.14 × 24 = 75.36 cm.
Hence, the circumference of the circle is 75.36 cm.
