If u(x)=-2x^2+3 and v(x)=1/x,what is the range of (uov)(x) ?
The range of the composition is:
R (-∞, 3)
How to find the range?
We have the functions:
u(x) = -2x² + 3
v(x) = 1/x
The composition gives:
(u o v)(x) = -2*v(x)² + 3
(u o v)(x) = -2(1/x)² + 3
Now, as x tends to infinity, the first term tends to zero (because the denominator is to large) then the function has an upper bound at 3.
Then as x decreases, the function decreases, when x tends to zero, the function tends to negative infinity.
So the range is:
R (-∞, 3)

What are the zeros of the polynomial function f(x) = x3 − x2 − 20x?
The other two zeros, which are x = 5 and x = -4.
To find the zeros of the polynomial f(x) = x³ − x² − 20x, we need to set the polynomial equal to zero and solve for x. This can be done by factoring out the common term x from each term of the polynomial:
f(x) = x(x² - x - 20) = 0
The zeros of the polynomial will be the values of x for which the product is zero. Since we already have x as one factor, one zero is x = 0. We then need to factor the quadratic, which is:
x² - x - 20
We can factor this quadratic to
(x - 5)(x + 4)
Thus, the other two zeros of the polynomial are x = 5 and x = -4.

Jose heard a song on the radio as he was flipping between stations. He immediately remembered that his brother, Juan, played that piece on his guitar. Jose's response was _____ .emotional physical intellectual none of the above
Answer:
Option C, Intellectual Response
Step-by-step explanation:
Intellectual response comes after intellectual thinking which includes deep , intensive and focused thinking in a certain direction. In this case, Jose after hearing a song on radio remembers that his brother used to play the same song on guitar. This is an intellectual response as after listening the song Jose's brain must have evaluated the past interactions associated with this song and hence after the evaluation he comes to know that he had heard the same song in past when his brother played it on his guitar.
Thus, option C is correct.
Which expression is represented by the number line?
Answer:
3 - 5.5 +1.5
Step-by-step explanation:
LEts analyze the given number line
We always start with 0
Arrow goes 3 units to the right, so we put positive 3
from 3 , the arrow ends at -2.5. Arrow goes to the left so we subtract to find the distance. -2.5-3= -5.5
from -2.5 we add 1.5 to reach -1
So the expressio becoems 3 and then subtract 5.5 and then add 1.5
3 - 5.5 +1.5
Simplify by combining like terms: -18+3(5x-2)+8=46
-18 +3(5x-2)+8=46
-18 + 15x-6 +8 = 46
-18 + 15x +2 =46
-16 +15x =46
15x = 62
x = 62/15 = 4.1333
A pasture is twice as long as it is wide. its area is 88,200 ft2. how wide is the pasture?
The width of the pasture is 210 feet.
What is the area of the rectangle?The area of the rectangle is the product of the length and width of a given rectangle.
The area of the rectangle = length × Width
We are given that pasture is twice as long as it is wide. its area is 88,200 ft2.
If the width is w and the length is l, then the length is 2w=l.
In addition,
The area of the rectangle = length × Width
l x w=88200
Using the area formula, Plugging 2w in for l, we get ;
2w x w = 88200
88200= 2w².
Now Dividing both sides by 2, we get;
w²=44100
w= √(44100)
w =210.

At which angle will the hexagon rotate onto itself? 60° 90° 120° 180°
Answer:
60
Step-by-step explanation:
Answer: The hexagon will rotate onto itself at 60°.
Step-by-step explanation:
A hexagon is a regular polygon with six sides) having all its sides and all its angles are equal.
For a regular polygon , Order of rotation of the figure = Number of sides .
i.e. Order of rotation for hexagon = 6
Let [tex]\theta[/tex] be the angle at which hexagon rotate onto itself, then we have
[tex]\theta=360^{\circ}\ \div6=60^{\circ}[/tex] [∵One complete rotation= [tex]360^{\circ}[/tex]]
Hence, The hexagon will rotate onto itself at 60°.

Match each function to its domain.
Answer:
f(x) = sqrt(x-5) Domain: all real numbers greater or equal to 5 f(x) = 7/(x-8) Domain: all real numbers except 8 f(x) = sqrt(x) Domain: all positive real numbers and 0 f(x) = 8x Domain: all real numbers The domain of a function is the set of all numbers for which that function is valid.
Step-by-step explanation:
6x equals 7-4y solve for y
The given values of x, the corresponding values of y are:
1. When x = -2, [tex]\(y = \frac{19}{4}\)[/tex]
2. When x = -1, [tex]\(y = \frac{13}{4}\)[/tex]
3. When x = 0, [tex]\(y = \frac{7}{4}\)[/tex]
Let's solve the equation [tex]\(6x = 7 - 4y\)[/tex] for y:
[tex]\[6x = 7 - 4y\][/tex]
First, isolate the term with y:
[tex]\[4y = 7 - 6x\][/tex]
Next, divide both sides by 4 to solve for y:
[tex]\[y = \frac{7 - 6x}{4}\][/tex]
Now, we can find the values of y for each given value of x:
1. For x = -2:
[tex]\[y = \frac{7 - 6(-2)}{4} = \frac{7 + 12}{4} = \frac{19}{4}\][/tex]
2. For x = -1:
[tex]\[y = \frac{7 - 6(-1)}{4} = \frac{7 + 6}{4} = \frac{13}{4}\][/tex]
3. For x = 0:
[tex]\[y = \frac{7 - 6(0)}{4} = \frac{7}{4}\][/tex]
Therefore, for the given values of x, the corresponding values of y are:
1. When x = -2, [tex]\(y = \frac{19}{4}\)[/tex]
2. When x = -1, [tex]\(y = \frac{13}{4}\)[/tex]
3. When x = 0, [tex]\(y = \frac{7}{4}\)[/tex]
Complete question:
Solve equation for y. Then find the value of y for each value of x.
6x = 7 - 4y; x = -2, -1, 0
Final answer:
To solve the equation 6x = 7 - 4y for y, subtract 7 from both sides and divide by -4 to isolate y.
Explanation:
To solve the equation 6x = 7 - 4y for y, we need to isolate y on one side of the equation. First, we can move the 7 to the other side by subtracting it from both sides:
6x - 7 = -4y
Next, we can divide both sides by -4 to solve for y:
y = (6x - 7) / -4

Plants A birch tree grew 2.5 inches in five months. A bean plant grew 8 inches in 10 months. It rosebush grew 5 inches in eight months. Which grew faster?
Answer:
Bean plant grew faster .
Step-by-step explanation:
As given
Plants A birch tree grew 2.5 inches in five months.
i.e 2.5 inches = 5 months
Now calculate birch tree in one month .
[tex]Birch\ tree\ grew\ in\ one\ month = \frac{2.5}{5}[/tex]
= 0.5 inches
As given
A bean plant grew 8 inches in 10 months.
i.e 8 inches = 10 months
Now calculate bean plant in one month .
[tex]Bean\ plant\ grew\ in\ one\ month = \frac{8}{10}[/tex]
= 0.8 inches
As given
It rosebush grew 5 inches in eight months.
i.e 5 inches = 8 months
Now calculate rosebush in one month .
[tex]Bean\ rosebush\ in\ one\ month = \frac{5}{8}[/tex]
= 0.63 inches (Approx)
Therefore Bean plant grew faster .
