Answer:
A) The model exists: f(x) = -3x^2 +4x -4
Step-by-step explanation:
A quadratic model will always exist for 3 given points, provided they are not on a line. In that case, a linear model is appropriate.
Here, the slope between -1 and 0 is positive, and the slope between 0 and 3 is negative. Thus, we know these points are not collinear, and a model must exist.
The model is most easily found using a quadratic regression tool. Such is shown in the attachment. It tells us that ...
f(x) = -3x^2 +4x -4
The answer is >>> 4 989 600
First get the factors of 24: 2*2*2*3Then the factors of 9: 3*3 Comparing the factors, the GCF is 3 Then you can rewrite the expression: 3*8 + 3*3 At this point, I'm not sure whether what you mean is really distributive property or not since this case is more of a factoring. 3*(8+3)
Answer:
If oscar had 3 apples then he took 2 from Tim and gave 1 to Mike.How many apples does he have?
Step-by-step explanation:
Area of the figure is 102 cm²
Step-by-step explanation:
- Step 1: Find the area of the square with side = 6 cm.
Area of the square = (side)² = 6² = 36 cm²
- Step 2: Find the area of the trapezoid.
Length of parallel side 1 = 7 cm
Length of parallel side 2 = 21 - 6 = 15 cm
Height = 6 cm
⇒ Area of the trapezoid = 1/2 × (Sum of parallel sides) × height
= 1/2 × (7 + 15) × 6
= 1/2 × 22 × 6 = 66 cm²
- Step 3: Find the area of the figure.
Area of the figure = Area of the square + Area of the trapezoid
= 36 + 66 = 102 cm²
