The polynomial function y = x3 -3x2 + 16x - 48 has only one non-repeated x-intercept. What do you know about the complex zeros o

earnstyle [38]

• First way to solve:
We'll manipulate the expression of the equation:

$y=x^3-3x^2+16x-48\\\\ y=x^2(x-3)+16(x-3)\\\\ y=(x-3)(x^2+16)$

If we have y=0:

$x-3=0~~~or~~~x^2+16=0\\\\ x=3~~~or~~~x^2=-16\\\\ x=3~~~or~~~x=\pm\sqrt{-16}\\\\ x=3~~~or~~~x=\pm4i$

Then, the function has one real zero (x=3) and two imaginary zeros (4i and -4i).

Answer: B

• Second way to solve:

The degree of the function is 3. So, the function has 3 complex zeros.

Since the coefficients of the function are reals, the imaginary roots are in a even number (a imaginary number and its conjugated)

The function "has only one non-repeated x-intercept", then there is only one real zero.

The number of zeros is 3 and there is 1 real zero. So, there are 2 imaginary zeros.

Answer: B.

Shane wants to plant 28 marigold plants and 36 rose plants in his garden. What is the greatest number of rows possible if each r

Dennis_Churaev [7]

Answer:

HCF=2*2=4

Step-by-step explanation:

Given : Shane wants to plant 28 marigold plants and 36 rose plants in his garden

To Find : the greatest number of rows possible each row has the same

number of marigold plants and the same number of rose plants.

Solution:

marigold plants = 28

rose plants = 36

To find the greatest number of rows possible if each row has the same

number of marigold plants and the same number of rose plants.

we need to find HCF of 28 and 36

28 = 2 x 2 x 7

36 = 2 x 2 x 3 x 3

HCF = 2 x 2 = 4

greatest number of rows possible is 4

(1 point) The length of an insect (L, in mm) is a function of the temperature during development (T , measured in ∘C according t

lawyer [7]

Answer:

$M(T)=1.1(7(8+T^{10})^{3})$ and $M(T)=1.1(7(8+22^{10})^{3})=1.44\time10^{41}$

Step-by-step explanation:

We have the next set of functions:

$L(T)=8+T^{10}$

$V(L)=7L^{3}$

$M(V)=1.1V$

We want to know M(T) then:

$M(V)=1.1V$ but we know that $V(L)=7L^{3}$ :

$M(L)=1.1(7L^{3})$ and we know that $L(T)=8+T^{10}$

$M(T)=1.1(7(8+T^{10})^{3})$

Finally using the value of 22º we have

$M(T)=1.1(7(8+22^{10})^{3})=1.44\time10^{41}$

Help please<br> I dont get this stuff

Lena [83]

Answer:

B) 3,375 / 3

Step-by-step explanation:

well, the way you find the volume of a cube is length * width * height. so, if you work backwards, then 3,375/3 = Length. (or width or height, since a cube is equal on all sides) sorry for bad explanations I dunno how to put it-

Goodluck on your homework/schoolwork!
