Y={2x-1)(x+4)(2x-3)(x-1)
Answers
Answer:
Y =4x^4 + 4x^3 − 37x^2 + 41x −12
Step-by-step explanation:
Y = (2x - 1 ) (x + 4) (2x - 3) (x - 1)
Using commutative property we can re-arrange RHS,
Y= (2x - 1) (2x - 3) (x + 4) (x - 1)
Using the property
[(x+a) (x+b) = x^2 + (a+b)*x +ab],
Y =
[(2x)^2 + (-1 - 3)*2x + (-1 )*(-3)] [x^2 + (4 - 1)*x + 4*(-1)]
From here onwards I would recommend u to do the calculation by your own bc I might have made mistakes
in the steps but I got right but still just check yourself if u copy all the steps as it is
Y = (4x^2 -8x + 3) (x^2 + 3x -4)
Y = 4x^4 + 12x^3 - 16x^2 -8x^3 -24x^2 + 32x + 3x^2 + 9x - 12
Y = 4x^4 + 4x^3 -37x^2 + 41x - 12
Here I got the answer right so my calculations will also might be right
I checked my answer if it's right using an app called "MathPapa" and it's a great app to solve algebra questions like urs. The screenshot of the answer using this app is here on the top. This is the longest question I have solved for anyone, bye and have a nice day ahead!

Rebecca is saving money to purchase a laptop which cost $1,099.51 she has already saved $354.20 and plans to continue saving $50.60 per week which inequality could be used to find W the number of weeks of Rebecca must save in order to purchase a laptop
Answers
Answer:
745.31+50.60w=1,099.51
W=7
Step-by-step explanation:
1st subtract 1099.51 from 354.20
2nd use your answer which is 745.31 and add that with how much she plans on saving for how ever long
3d to find out how many weeks which is 50.60*w you need to first minus 745.31 from both sides
4th so 745.31- 745.31 and 1099.51-745.31 =354.2 or .20
5th divide 354.2 by 50.60 =7
So overall w= 7

An equation for a toy boat is bobbing on the water is in the sinusoidal form which we can write as, D(t) = 0.2 sin2t +1
What is an Equation ?
An equation is a mathematical term, which indicates that the value of two algebraic expressions are equal. There are various parts of an equation which are, coefficients, variables, constants, terms, operators, expressions, and equal to sign.
For example, D(t) = acos2t +b
Types of equation
1. Linear Equation
2. Quadratic Equation
3. Cubic Equation
Given information,
Equation of bobbing, D(t) = a sinbt + d
By graph we can say that it is compressed two times,
So, value of b will be, 2
At t =0, height from the floor is 1 m
1 = a sin(2×0) + d
d = 0
At t =π/4, height from the floor is 1.2 m
1.2 = a sin(2×π/4) + 1
a = 0.2
By graph we can say that it is compressed two times,
So, value of b will be 2
Hence, An equation is D(t) = 0.2 sin2t +1

Let R be the region in the first quadrant bounded above by the graph of y=1−x^2 and below by the graph of y=1−√x, as shown in the figure above. What is the area of the region?
Answers
1/3
have a good day/night
If R be the region in the first quadrant bounded above by the graph of y=1−x² and below by the graph of y=1−√x then area is 1/3.
To find the area of the region bounded by the graphs of y = 1 - x² and y = 1 - √x in the first quadrant.
we need to determine the points of intersection and integrate the difference between the two functions over that interval.
To find the points of intersection, we set the two functions equal to each other:
1 - x²= 1 - √x
x²= √x
Squaring both sides again, we have:
x⁴ = x
x(x³ - 1) = 0
This equation gives us two potential solutions: x = 0 and x = 1.
To determine the limits of integration, we need to find the x-value where the two curves intersect.
Since y = 1 - √x represents the upper curve, we can set the two functions equal to each other and solve for x:
1 - x² = 1 - √x
x² = √x
x⁴ = x
Since we are only interested in the first quadrant, the solution x = 0 is not relevant.
Therefore, the only point of intersection is x = 1.
Integrating the difference between the two functions over the interval [0, 1] will give us the area of the region R:
A = ∫[0, 1] (1 - x²) - (1 - √x) dx
Expanding and simplifying the integrand:
A = ∫[0, 1] 1 - x² - 1 + √x dx
A = ∫[0, 1] -x² + √x dx
Integrating each term separately:
A = [-x³/3 + (2/3)x^(3/2)]|[0, 1]
A = [-(1/3) + (2/3)] - [0]
A = 1/3
Therefore, the area of the region R is 1/3.

A.
1 meter per second
5 meters per second
B.
C.

D.
11 meters per second
Answers
Using proportions, it is found that the difference between the speeds of the two boys was of:
A. 1 meter per second.
What is a proportion?A proportion is a fraction of a total amount. Following this concept, velocity is distance divided by time.
In this problem, Miguel ran 1 lap = 400 meters each 240/3 = 80 seconds, hence his speed is given by:
sM = 400/80 = 5 m/s.
Joseph ran 400 metters each 200/3 = 66.67 seconds, hence his speed is given by:
sJ = 400/66.67 = 6 m/s.
The difference is given by:
6 m/s - 5 m/s = 1m/s.
Hence, option A is correct.

Remark
√-12
The square root of -12 must have an i in it somewhere. If it does not, then the minus sign stays under the root sign. If you take the root of -1 you get i, and that is outside √ sign.
Solution
A is incorrect. i is on the outside of the root sign.
B is the answer.
C does not seem to take the square root of anything except -1 so it is incorrect.
D Has no i anywhere and the -1 is incorrectly placed. D is wrong
E is just wrong. The minus should disappear once the square root of -1 is taken. 12 has a root that has not been declared.
