The weight of a puppy was monitored for the first year of its life. The weight, in grams, of the puppy has a strong linear relationship with the number of months, x, since
birth. The relationship can be modeled by the function f(x) = 1,200x + 400. What is the meaning of the y-intercept of the function?
A. The puppy weighed about 400 grams at birth
B. The puppy weighed about 1200 grams at birth
C. The weight of the puppy increases by about 400 grams per month
D. The weight of the puppy increases by about 1200 grams per month
Answer:
y-intercept is 400 so it means the puppy weighed 400 at birth

1/4 OF MY POINTS For this assignment, you will use sinusoids to model mathematical and real-world problems.
Background Information
Data sets that are cyclical, harmonic, oscillating, or periodic can be modeled with sinusoidal functions.
Finding key features such as minimum, maximum, amplitude, period, and frequency are helpful in
determining a sinusoidal model. Recall that the general forms of equations of sinusoids can be in these
forms: y = a sin(b(x – h)) + k or y = a cos(b(x – h)) + k.

A quadratic equation can be written in vertex form or i n standard form. Sometimes one form is more beneficial than the other. Identify which form would be more helpful if you needed to do each task listed below and explain why.
a. Factor the equation.
b. Graph the parabola.
c. Identify the vertex, minimum, or maximum of the parabola.
d. Solve the equation using the quadratic formula
Answer:
a. Standard form
b. Vertex form
c. Vertex form
d. Standard form
Step-by-step explanation:
The vertex form of a quadratic equation is y = a·(x - h)² + k
The standard form of a quadratic equation is y = a·x² + b·x + c
Therefore;
a. In order to factor the equation, the vertex form needs to be expanded to the standard form first, to obtain the factors of the equation
b. The parabola is easily graphed with the information on the vertex given in the vertex form of the quadratic equation
c. The vertex, minimum or maximum of the parabola are easily obtained in the vertex form of the quadratic equation
d. The quadratic formula is defined based on the standard form of the quadratic equation
The forms of a quadratic equation are the ways the equation can be written.
The tasks and the required forms are:
Factor the equation - Standard formGraph the parabola - Vertex formIdentify the vertex, minimum or maximum - Vertex formQuadratic formula - Standard formThe standard form of a quadratic equation is:
[tex]\mathbf{y =ax^2 + bx + c}[/tex]
The above form can be used to calculate the roots of a quadratic equation, using the following quadratic formula
[tex]\mathbf{x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}}[/tex]
Also, a quadratic equation can be easily factorized from [tex]\mathbf{y =ax^2 + bx + c}[/tex]
This means that, the standard form can be used for (a) and (d)
The vertex form of a quadratic equation is:
[tex]\mathbf{y = a(x - h)^2 + k}[/tex]
The above form is used to
Identify the vertexIdentify the maximum and the minimum points of a parabolaThis means that, the vertex form can be used for (b) and (c)

A pitcher in a major league baseball game threw 100 pitches. If 36 of the pitches were balls and 64 were strikes, what is the ratio of balls to strikes for that game?
Answer:
The ratio of balls to strikes is 9 : 16
Step-by-step explanation:
From the question, a pitcher in a baseball game threw a total of 100 pitches in which some were balls and others were strikes. 36 of them were balls and 64 were strikes.
To determine the ratio of balls to strikes for the game, we will divide the number of balls by the number of strikes.
That is,
Ratio of balls to strikes = Number of balls / Number of strikes
Number of balls = 36
Number of strikes = 64
Therefore,
Ratio of balls to strikes = 36 / 64
Ratio of balls to strikes = 9 / 16
Hence, the ratio of balls to strikes is 9 : 16.

$36000. For every year after it is purchased, the car loses 17% of its value due to depreciation. What is the value of the car after 64 months? find in exponential function grade 11 math
Answer:
$13,320Step-by-step explanation:
The expression for depreciation is
V=C(1-r)^t ,
where V is the value of the car after t years,
C is the original cost, and
r the rate of depreciation. If a car
given
C=$36000
r=17%= 0.17
t in years 64/12= 5.33years
Substituting to the formula we have
V=36000(1-0.17)^5.33
V=36000(0.83)^5.33
V=36000*0.370
V=13,320
the value will be $13,320
