x^4-5x^2+4=0
Answers
Answer:
x = 4 and x = -4
x = 1 and x = -1
Step-by-step explanation:
let u = x^2
Then,
u^2-5u+4 = 0
(u - 4)(u - 1) = 0
u = 4 and u = 1
we substitute back for u
Then,
x^2 = 4
x = 4 and x = -4
x^2 = 1
x = 1 and x = -1
The solutions to the equation x⁴ - 5x² + 4 = 0 are x = ±2 and x = ±1.
To solve the equation x⁴ - 5x² + 4 = 0, we can use substitution to simplify it.
Let's take a new variable, u = x².
Substituting u into the equation, we get:
u² - 5u + 4 = 0
Now, we can factor this quadratic equation:
(u - 4)(u - 1) = 0
Setting each factor equal to zero, we have:
u - 4 = 0 or u - 1 = 0
Solving for u in each case:
u = 4 or u = 1
Now, we substitute back the original variable x:
For u = 4:
x² = 4
Taking the square root of both sides:
x = ±2
For u = 1:
x² = 1
Taking the square root of both sides:
x = ±1
Therefore, the solutions to the equation x⁴ - 5x² + 4 = 0 are x = ±2 and x = ±1.

Answer:
36 units squared
Step-by-step explanation:
Since this is kind of a weird shape, we can split it into two smaller shapes, a triangle, and a rectangle.
The rectangle is 6 units wide, and 4 units long. Multiply the length and width to get 24 units squared.
The triangle has a base of 6 and a height of 4, so multiply the base and height, then divide by 2. 6 times 4 is 24 and that divided by 2 is 12.
Finally add the two areas together. 24+12=36 units squared.
Answer:
36
Step-by-step explanation:
Since the two triangles on the bottom are the same, we can flip one of them over onto the other, and they will make a square. Then the top rectangle is 24, and the bottom new square would be 12 and 24 plus 12 is 36

According to a personal trainer's study, the equation yˆ=8.6067x+116.6567 models the average number of calories burned by a 160 lb individual, where x is amount of time spent weight lifting, in minutes, given the individual started the workout with a 10-minute jog.
According to this regression equation, what is the approximate calories burned for an individual who spent 30 minutes weight lifting?
Answers
Answer:
An individual who spent 30 minutes weight lifting will burn approximately 142.4768 calories.
Step-by-step explanation:
Given;
yˆ = 8.6067x + 116.6567 ............................... (1)
Where;
yˆ = The average number of calories burned by a 160 lb individual
x = Amount of time spent weight lifting
Since x is amount of time spent weight lifting, this implies that for an individual who spent 30 minutes weight lifting, x = 30
Substituting x = 30 into equation (1), we have:
yˆ = (8.6067 * 30) + 116.6567
yˆ = 25.8201 + 116.6567
yˆ = 142.4768
Therefore, an individual who spent 30 minutes weight lifting will burn approximately 142.4768 calories.

in the diagram below, line segment AB is drawn. Point A has been mapped to image point A' by the use of a translation.
Answers
a. B'(9,-1)
b. AB is parallel to A'B'
Explanation
a. Coordinate of A is (-5,2) and it is translated 6 units right and 3 units up (x+6, y+3).
Now A'(-5+6, 2+3) = A' (1,5)
Thus B's coordinate is (3,-4) and it is also translated in the same direction as A.
Now, B' (3+6, -4+3) = B'(9, -1)
Therefore, the translated point is A'(1,5) and B'(9,-1)
b. AB is parallel to A'B', Because the line segment obtained by translation is parallel to the original segment.
What is translation?A translation is a geometric change in Euclidean geometry that involves moving each point in a figure, shape, or space by the same amount in one direction. A translation can also be thought of as moving the origin of the coordinate system or as adding a constant vector to each point. Any translation in a Euclidean space is an isometry.To learn more about translation, refer to https://brainly.com/question/1046778

Given
slope = m = 3point (5, 10)We know that the point-slope form of the line equation is
[tex]y-y_1=m\left(x-x_1\right)[/tex]

Answer:
Step-by-step explanation:
The first option is false because the minimum is y = -8 or more, based on the table.
The second option is false because the intervals decrease until y = 2.
The third option is true because the intervals decrease from x = -3 to x = 2 then is the same from x = 1 to x = 3 then increases from x = 3 to x = 5.
The four option is false because based on the table the function has a maximum of y = 16 or more.
The fifth option is false based on the table.
The sixth option is true because if we start at (0,0) and move to the left or x = -infinity, the y-values increase. When we start from (0,0) and move to the right x = infinite, the y-values increase.
The seventh option is false.
The eighth option is true based on the third option.
The last option is true based on the table.

Answers
Answer:

Step-by-step explanation:
hope this helps
Answer:
70 cups
Step-by-step explanation:
C. P. of lemonade supplies = $5.25
S. P. of one cup of lemonade = $1.50
Let us assume that she should sell n cups of lemonade to make a profit of $100.00.
Therefore, S. P of n cups = $1.50n
Since,
Profit = S. P. - C. P.
Therefore,
100 = 1.5n - 5.25
100 + 5.25 = 1.5n
105.25 = 1.5n
n = 105.25/1.5
n = 70.1666667
n = 70 cups

One palm tree is located at (−2 1/2, −2). The other palm tree is a reflection of point T across the x-axis. What are the coordinates of point R?
Answers
Answer:
-2.5, 2
Step-by-step explanation:
When you reflect across the x axis you have to flip the sign of the y coordinate. When you reflect across the x axis you have to flip the sign of the x coordinate.
Answer:
(−2 1/2, 2)
Step-by-step explanation:
Since, one palm tree is located at (−2 1/2, −2). The other palm tree is a reflection of point T across the x-axis.
Therefore, for other palm tree x- coordinate will remain same and y-coordinate will flip over x- axis to become positive.
Thus, the coordinates of point R would be (−2 1/2, 2)
