Answer:
The only function that has only one zero at -6 is f(x) = (x + 6)(x + 6)
Step-by-step explanation:
We have a function:
f(x)=(x+6)(x+6)
This function is also equal to f(x)=(x+6)^2
This is the square of the binomial. It has only one zero
f(x)=(x+6)^2 = 0
If we take square root we get:
√(x+6)^2 = 0
x+6 =0
x= -6
The only function that has only one zero at -6 is f(x) = (x + 6)(x + 6)....
Answer:
Induction produces an electromagnetic field in a coil to transfer energy to a work piece to be heated. When the electrical current passes along a wire, a magnetic field is produced around that wire

Answer
2890
Step-by-step explanation:
2,890 meters^2 is grass
Step-by-step explanation:
First find the area of the garden
Area of a rectangle can be found using:
a=lw
a=85*50
a=4,250 meters^2
We know that 32% of the area is flowers, so we can multiply 32% and 4250
32%*4250
Convert 32% to a decimal by dividing by 100
32%/100=0.32
0.32*4250=1360
So, 1360 meters^2 is flowers.
The rest must be grass, so we can find the difference between the total area and the flowers
4250-1360=2890
We can divide the shape into a rectangle and a triangle:
(1) Area of rectangle = length*width
From the graph we can see that the length of the rectangle is 7 units and the width is 5 units
Area = 7*5 = 35 units^2
(2) Area of triangle = 1/2*bh
From the graph we can see that the base of the triangle is 4 units and its height is 5 units
Area = 1/2*4*5 = 10 units^2
(3) Total area = area of triangle + area of rectangle
= 10 + 35
= 45 units^2
