Point (0,3) is the y - intercept of the function because it is the point where x = 0.

A y - intercept is when x is 0 and y is a point

If you get a equation like this:

y = 4x

The y - intercept would be zero since there is no number for y

If you get a equation like this

y = 4x + 1

The The y - intercept would be 1 since there is a b

Standard form: y = mx + b

b = y-intercept

HELP PLZ THIS IS TIMED WILL GIVE BRAINLIEST

(x² +9) and g(x) are factors of f(x).
That is, (x² +9)(g(x)) = f(x).

The roots of (x² +9) are roots of f(x). They are 3i and -3i.

The factor (x² +9) has degree 2, so f(x) has degree at least 2.

We cannot say anything about the x- or y-intercepts based on this information.

Imaginary roots usually come in even numbers (2, 4, etc.) for the polynomials we study. The information given here does not support the idea of 3 imaginary roots for f(x).

Calculate the 1st quartile of the data set below: 53, 54, 71, 95, 108, 110, 115, 120, 128, 128, 129, 141, 143, 158, 193

<span>The first quartile, is the median of the lower half of the data set. That means we have to find the median. If you write these numbers down on a piece of paper and x them out you can easily find the median! The median is 120. Hope this helps! <3</span>

Crecimiento de arboles
denpristay [2]

Queremos encontrar la altura de las plantas luego de t años, dado que conocemos la altura inicial y la velocidad de crecimiento.

La ecuación de la altura es:

h(t) = 0.75*t^2 + 5*t + 12

Con ella veremos que los arbustos miden 69cm cuando son vendidos.

<em>Veamos como resolver esto.</em>

h(t) es la función que modela la altura de las plantas.

Sabemos que:

\frac{dh(t)}{dt} = 1.5*t + 5

Sí integramos, obtendremos:

h(t) = (1/2)*1.5*t^2 + 5*t + c

donde C es una constante de integración, la cual representa la altura inicial (para t = 0) de las plantas, notar que:

h(0) = c

Y sabemos que las plantas miden 12 cm cuando son plantadas, entonces c = 12.

La ecuación de la altura es entonces:

h(t) = 0.75*t^2 + 5*t + 12

Esta ecuación nos da la altura en centimetros a tiempo t.

Sabemos que los arbustos se venden luego de 6 años, entonces la altura que tendran cuando son vendidos es:

h(6) = 0.75*6^2 + 5*6 + 12 = 69

Es decir, los arbustos miden 69cm cuando son vendidos.
