Answer:
<u>42.25π m²</u>
Step-by-step explanation:
Let's solve!
⇒ Take the radius of the lawn to be 'r'
===========================================================
Then, area of the path equals :
⇒ Area of (lawn + path) - Area of lawn
⇒ π (r + 2)² - πr² = 30π
⇒ πr² - πr² + 4πr + 4π = 30π
⇒ 4πr = 26π
⇒ r = 6.5 m
===========================================================
Area of the lawn :
⇒ Area = πr²
⇒ Area = π × (6.5)²
⇒ Area = <u>42.25π m²</u>
It will take 15 hours. Because the train has a speed of 18 mph, you just have to divide 270 by 18 which makes 15. The train goes 18 mph, so it is 15 hours.
Answer:
The table can be filled as shown below.
Step-by-step explanation:
The first function is
Put different values of x and find values of f(x).
For x=-2
For x=-1
Similarly for x=0,1,2 the value of f(x) are 8,12,16 respectively.
The second function is
For x= -6
For x= -3
Similarly for x=0,3,6 the value of f(x) are 8,10,12 respectively.
The third function is
For x= 2
For x= 3
Similarly for x=4,5,6 the value of f(x) are 32,132,632 respectively.
The fourth function is
For x=-4
For x=-3
Similarly for x=-2,-1,0 the value of f(x) are 11,-1,-4 respectively.
Answer: 47°

Step-by-step explanation:
The Midpoint Formula works exactly the same way. If you need to find the point that is exactly halfway between two given points, just average the x-values and the y-values.
