F(x) = (x+3)(x-2) → f(x) = x² + x - 6
1st : The coefficient a > 0, the parabola opens upward,
2nd: The x-= intercepts are x = - 3 & x= +2 ( the values that render f(x) = 0
3rd: For x = 0, y = - 6 (this is y intercept)
The only figure that corresponds to those specifications is the 1st graph
Answer:
Width = 5 inches
Length = 9 inches
Step-by-step explanation:
The paper;
Length = (x + 4) inches
Width = x inches
The area is close as possible to 50 square inches.
Since this paper is rectangular in shape; the area of a rectangle is given by:
Area = Length × Width
∴ (x + 4) * x = 50 square inches
x² + 4x = 50
Let the area be equal to 45 square inches;
Applying the quadratic formula, x = 5 or -9
But since we are dealing with length measurements, the value of x = 5 inches.
So the width = 5 inches and;
length = 5 + 4 = 9 inches.
Hey there!
22100 : 19.3
x : 100
Nearest whole number = 114508
Answer : Total employees = 114,508
Hope this helps. - M
The first one is : (9)
By submitting --> 9
For every "X" in both of the equations its = 59
And because the question told us that the perimeter is 118 , so we multiply the 59 by 2
59x2 = 118
So , the answer is (9)
the second one is : (19)
the coverage value is 5$ , and the cost p/m is 0.15$ , so we subtract 7.85$ - 5$ we will get = 2.85$ , now by dividing 2.85$/0.15$ we will get = 19 , and that is the number of miles.
Good Luck!
The question is impossible to answer since. Since you can't answer that without knowing the volume of the bar to start with. The only given is the length, there should be other dimensions like the width and area of the cross-section, for instance.
Volume = Width x Depth x Height in all cases, so when you know the volume. But to solve for the height of the cuboid, the equation is V/100 (because the base of the cuboid is 100 cm^2)
