Answer:
x=−y26+y3−136
Explanation:
Given -
Vertex (−2,1)
Directrix x=1
The vertex is in the 2nd quadrant. The directrix is parallel to the y-axis. So, the parabola opens to the left. The vertex of the parabola is not the origin. Then its general form is -
(y−k)2=−4.a.(x−h)
Where -
h and k are the coordinates of the vertex.
h=−2)
k=1
a=1.5 half the distance between Directrix and vertex [= distance between focus and vertex]
Substitute these values in the equation
(y−1)2=−4.1.5.(x+2)
y2−2y+1=−6x−12
−6x−12=y2−2y+1
−6x=y2−2y+1+12
x=y2−6−2y−6+13−6
x=−y26+y3−136
Answer:
$546
Step-by-step explanation:
Given
Amount, P = $650
Rate, R = 12%
Period, T = 7 months
Required
Determine the amount paid.
We'll solve this using simple interest formula, as thus
Substitute values for T, R and P
<em>Hence, Henry's withdrawal is $546</em>
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>
