Answer:
f(-5) = 25
f(0) = -2
f(5) = 16
Step-by-step explanation:
Given the functions;
To get f(-5), we will use the function of x where x is less than 0 since -5 is less than zero
at where x < 0, f(x) = x^2
f(-5) = (-5)^2
f(-5) = 25
b) For f(0), where the point where x = 0, f(x)= -2
Hence the value of f(o) = -2
c) For f(5), the function where x > 5 is f(x) = 2x+6
f(x) = 2x+6
f(5) = 2(5)+6
f(5) = 16
You can put the 2 circles together to get 1 circle
so basically we just find
area of rectangle taht is 8ft by 18ft
and area of ciecle with disameter of 8
area rectangle=18 times 8=144 square feet
area of ciecle=pir^2
d/2=r, 8/2=4
area=pi4^2=16pi, pi=3.14 so then
50.24
toal is rectangle+circles=144+50.24=194.24 suare feet
rounded
194 square feet
Answer:
(y, -x)
Step-by-step explanation:
Rotation of 90°
(Clockwise)
(x, y) ---> (y, -x)
Rotation of 90°
(CounterClockwise)
(x, y) --> (-y, x)
Rotation of 180°
(Both Clockwise and Counterclockwise)
(x, y) ---> (-x, -y)
Rotation of 270°
(Clockwise)
(x, y) ---> (-y, x)
Rotation of 270°
(CounterClockwise)
(x, y) ---> (y, -x)
x² + 7x - 4 = 0
a = 1, b = 7, c = -4
x = [-b +/- √(b² - 4ac)]/2a
= [-7 +/- √(49 + 4)]/2
= (-7 +/- √53)/2
