Answer:
4th degree polynomial with leading coefficient of 1.
As x goes to negative or positive infinity, y goes to positive infinity in both cases.
Step-by-step explanation:
The degree of a polynomial is the highest exponent on the variable. Here it is 4.
The leading coefficient is the coefficient on the the term with the highest degree, Here there is none so it is 1.
The end behavior is how x and y behave at negative and positive infinity. When graphed, this equation has a W shape. This means at each end y goes to positive infinity.
Answer:
y = -0.6x^2 + 5x + 6
Step-by-step explanation:
First, find the equation of a linear line that passes through the points (0,6) and (3, 15.6) in the slope intercept form, y = mx + b. We know that the line has a y-intercept of 6, so b = 6. Substitute 3 for x, 15.6 for y, and 6 for b to find m.
y = mx + b
15.6 = 3m + 6
9.6 = 3m
m = 3.2
y = 3.2x + 6
y = a(x - 0)(x - 3) + 3.2x + 6
y = a(x)(x - 3) + 3.2x + 6
Finally, substitute 10 for x and -4 for y in the equation above to find a.
-4 = a(10)(10 - 3) + 3.2*10 + 6
-4 = a(10)(7) + 32 + 6
-4 = 70a + 38
-42 = 70a
a = -0.6
Simplify to write in standard form.
y = -0.6(x)(x - 3) + 3.2x + 6
y = -0.6x^2 + 5x + 6
Answer is C. y=1/3x+3
the slope is going to be 1/3 (opposite of -3/1) and if go to the point 3,4 and go down one and left 3, you will get a y intercept as 3
Here we can first find the area of yard and then subtract the area of vegetable garden to get the required area.
The formula to find area is given by:

Now we find area of yard:
length is 25 ft and width is 15 ft.

Area of yard = 375 ft²
Area of vegetable garden:
length = 8ft and width =8ft
So the vegetable garden is a square.
Area = 8*8
Area of vegetable garden =64 ft²
Area of backyard to be laid with grass = Area of yard-Area of vegetable garden
Area required = 375 -64 = 311 ft²
Answer : The area of backyard in which grass is to be laid is 311 square feet.
