The easiest thing to do to solve all of these is to use the quadratic equation.

The first number (the one attached to x^2) is equal to a. The second number (the one attached to x) is b. The final number (the one with nothing attached) is c.
Answer:
It is expected that linearization beyond age 20 will be use a function whose slope is monotonously decreasing.
Step-by-step explanation:
The linearization of the data by first order polynomials may be reasonable for the set of values of age between ages from 5 to 15 years, but it is inadequate beyond, since the fourth point, located at
, in growing at a lower slope. It is expected that function will be monotonously decreasing and we need to use models alternative to first order polynomials as either second order polynomic models or exponential models.
Answer:
B
Step-by-step explanation:
(f+g)(x) means add f(x) and g(x) together:
(x/2)-2 + 2x^2 +x -3
collect all the like terms:
2x^2
(x/2) + x = 3/2x (explanation below)
-2 -3 = -5
x/2 + x can be turned to 1x/2 + 2/2x (2/2 = 1, so when you simplify it to 1x, it is still x)
Answer:
Please check the explanation.
Step-by-step explanation:
Given
- The location of Point A on the number line = -13.4
- The location of Point B on the number line = 14
- The location of Point C on the number line = 19.9
The location of Point C on the number line = 19.9
Thus, the distance or length between B and C can be calculated by subtracting the point B units from point C units.
BC = 19.9 - 14
= 5.9 units
Therefore,
BC = 5.9 units
Also, the distance or length between C and A can be calculated by subtracting the point C units from point A units.
CA = -13.4-19.9
= -33.3 units
Therefore,
CA = -33.3 units
As the length or distance can not be negative, hence
CA = 33.3 units
Slope is y=1 and y-intercept is -3
