Answer:
Step-by-step explanation:
Complete the square
+ 2x - 13 = 0
+ 2x = 13
+ 2x +
= 13 +1 (take 1/2 of the b term , the 2 )
+ 2x + 1 = 14
(x +1)^2 = 14

Option A: is the dilation factor
Explanation:
The Coordinates of the square ABCD are A(-21,18), B(-12,18), C(-12,9), D(-21,9)
Also, the coordinates of the square A'B'C'D' are A'(–7, 6), B'(-4,6), C'(-4,3), D'(-8,3)
Now, we shall determine the scale factor in the dilation if the coordinates A' and C'.
Since, the dilation is the enlargement of the image in the same shape but different size.
To determine the scale factor, let us divide A'C' by AC
Thus, we have,
Also,
Dividing A'C' by AC, we have,
Thus, is the dilation factor
For this case we have the following function:
Where,
g: number of gallons of gas
M (g): number of miles that Danny's truck travels
We know that the maximum capacity is 20 gallons of gas.
Therefore, the maximum distance the truck can travel is given by:
Thus, the domain of the function is:
The range of the function is:
Answer:
A domain and range that are reasonable for the function are:
D. D: 0 ≤ g ≤ 20
R: 0 ≤ M (g) ≤ 340
Usando las relaciones entre velocidad, distancia y tiempo, se encuentra que ella condujo a una velocidad media de 90,5 km/h.
--------------------------
La <u>velocidad </u><u>es la distancia dividida por el tiempo</u>, por lo que:
- Total de 135,75 km, o sea,
- Llego en 1,5 horas, o sea,
La velocidad es:
División de decimales, o sea, seguimos multiplicando los números por 10 hasta que ninguno sea decimal:
Ella condujo a una velocidad media de 90,5 km/h.
