Answer:
[tex]\frac{(a^{2}*\pi )}{2} + 8a[/tex]
Step-by-step explanation:
We need to find the area of that semi circle and add it to the area of the rectangle. We can easily find the area of the rectangle with the equation length times width which is 4 *2a or 8a.
The radius is a and since the area of a semi-circle is (pi*r^2)/2, we can get a^2*pi/2.
Therefore, the equation would be [tex]\frac{(a^{2}*\pi )}{2} + 8a[/tex]

What is the Y-INTERCEPT of the line y = 3x - 5
Answers
Answer:
(0,-5)
Step-by-step explanation:
In y = mx+b, b is the y-value of the y-intercept.
Here, b = -5.
Note: the y-intercept is a POINT, not a value.
Step-by-step explanation:
Hey there!
Given equation is; y= 3x-5.
Comparing the equation with y= mx+b, where "b" is y-intercept. we get;
y-intercept= -5
Therefore, y-intercept of the equation is"-5".

How can knowing the slope and y-intercept help you graph an equation?
Answers
Answer:
To graph the equation of a line, we plot at least two points whose coordinates satisfy the equation, and then connect the points with a line. We call these equations "linear" because the graph of these equations is a straight line.There are two important things that can help you graph an equation, slope and y-intercept.SlopeWe're familiar with the word "slope" as it relates to mountains. Skiers and snowboarders refer to "hitting the slopes." On the coordinate plane, the steepness, or slant, of a line is called the slope. Slope is the ratio of the change in the y-value over the change in the x-value. Carpenters and builders call this ratio the "rise over the run." Using any two points on a line, you can calculate its slope using this formula.GIVING BRAINLIEST easy question
A bridge is 10 m above a railroad track and at right angles to it. A train is running at the rate of 20 m/s passes under the center of the bridge at the same instant that a car running 15 m/s reaches that point. How rapidly are they separating 3 seconds later?
Answers
x = 20t, y = 15t, z = 10
let s be thedistance between them at time t,
s^2 = (20t)^2 + (15t)^2 + 10^2 = 625t^2 + 100
2s ds/dt = 1250t
ds/dt = 625t/s
when t = 3, s = √(625*9+100) = 75.6637
ds/dt = 625*3/75.6637 = 24.78 m/s
The time taken that should be rapidly are distinct 3 seconds later should be considered as 24.78 m/s.
Calculation of the time taken:Here the point should be considered directly under the center of the bridge as the origin
Here
x = 20t, y = 15t, z = 10
let us assume s be the distance between them at time t,
So it be like
[tex]s^2 = (20t)^2 + (15t)^2 + 10^2 = 625t^2 + 100[/tex]
2s ds/dt = 1250t
ds/dt = 625t/s
Now at the time when
t = 3,
[tex]s = \sqrt (625*9+100)[/tex] = 75.6637
So,
ds/dt = [tex]625*3/75.6637[/tex] = 24.78 m/s

Write an equation in the form y=Mx+b to model the given representation
Answers
Answer:
y= 20x +30
Step-by-step explanation:
y - intercept of the graph is 30
Slope of the graph is [tex]\frac{20}{1}[/tex]
Answer:
y = 20x + 30
Step-by-step explanation:
y=mx+b
b value = y-intercept, so you find where the line crosses the y-axis.
Find point at (0,30); b = 30
m value = rise/run (rise over run) (y/x)
find the next point that the graph intersects at and count add to it to find 30.
the closest point is at (-1,10)
go back to rise/run
30-10 = 20
0-(-1) = 1
20/1 =20 is your m value
plug m value and b value into equation to form your line.
y=20x+30
