Answer:
Work shown below!
Step-by-step explanation:
[tex]x^{4}-5x^{2} +4[/tex] = [tex]0[/tex]
[tex]A[/tex] = [tex]x^{2}[/tex]
[tex]A^{2} -5A+4[/tex] = [tex]0[/tex]
[tex](A-1)(A-4)[/tex] = [tex]0[/tex]
[tex](x^{2}-1)(x^{2} -4) =0\\(x-1)(x+1)(x-2)(x+2)=0[/tex]
x - 1 = 0
Add 1 to both sides;
x = 1
x + 1 = 0
Subtract 1 from both sides;
x = -1
x - 2 = 0
Add 2 to both sides;
x = 2
x + 2 = 0
Subtract 2 from both sides;
x = -2
Let f(x) = x + 7 and g(x) = x − 4. Find f(x) ⋅ g(x). (1 point) x2 − 3x −28 x2 − 3x − 11 x2 + 3x − 28 x2 + 3x − 11
[tex]f(x)=x+7\\g(x)=x-4\\f(x)*g(x)=(x+7)(x-4)\\f(x)*g(x)=x^2+3x-28[/tex]
So it's x^2+3x-28

Answer:
Y = 5
Step-by-step explanation:
Answer:
y=5
Step-by-step explanation:
15(12-y)+9y=150 do the () first
180-15y+9y=150 combine the y terms
180-6y=150 subtract 180 from both sides
-6y= -30 divide by -6

Second Answer: 1262.28571429
Answer:
Step-by-step explanation:
first subtract 7,000 because its the largest and easiest number to subtract and calculate, you get 1,836 then subtract 1,400 because the its, again the easiest number to do so, from there you get 436 then you subtract 420 for the same reason, then you get 16 subtract 14 to get 2, then add the previous numbers to get 1262, now we have to subtract with decimals so every whole number we use will actually be a decimal, add all those numbers together for a total of 1262.285714 with a line on the top of it signaling that it is never-ending which if we kept dividing we would get back to the same numbers so it stops here.

In the image which shows the complex number w and z+w, the value of the complex number Z is -3+6i.
How to find value of complex number from graph?
To find the value of a complex number from the graph, follow the steps below.
On the graph where x-axis represents the real line, the distance of the point give the real number.On the graph where y-axis represents the imaginary line, the distance of the point give the imaginary number, which is written with complex number i.The image shows w and z + w. The point w is 1 units left from the imaginary axis. Thus, the real number for w is -1.
This number is 2 units down. Thus, the complex number represent the point w is,
[tex]w=-1-2i[/tex] ......1
Similarly, z+w is 4 units left and 4 units up. Thus, the complex number represent z+w is,
[tex]z+w=-4+4i[/tex] ......2
Substrate equation 1 from equation 2,
[tex]z+w-w=-4+4i-(-1-2i)\\z=-4+4i+1+2i\\z=-3+6i[/tex]
Hence, In the image which shows the complex number w and z+w, the value of the complex number Z is -3+6i.

The total cost in dollars for Larry to have his birthday party at a local
Trampoline Park can be found using the function t = 6.95p + 29.95, where p is
the number of people who will attend the party. If Larry only has $70 to spend on
his party, which of the following could represent the domain of the function?
Answer:
He can have 5 people at max
Step-by-step explanation:
He can only have 5 people at max which would cost $64.70, since if there were one more it'd cost $71.65. So the equation would be
T = 6.95p + 29.95 { 0 ≤ x ≤ 5 }
The domain can be represented as 0 ≤ p < 6
What is domain of the function ?Domain is the set of all inputs for which the function is valid, whereas the range of a function is the set of outputs that the function will produce. Also, we can define domain and range as, domain is the set of numbers which are valid values for the independent variable. The range is the set of valid numbers for the dependent variable.
We have
t = 6.95p + 29.95
Amount = $70
Required
Determine the domain
First, we need to solve for p
Substitute $70 for t in t = 6.95p + 29.95
70 = 6.95p + 29.95
Collect Like Terms
6.95p = 70 - 29.95
6.95p = 40.05
Solve for p
p = 40.05/6.95
p = 5.76
This implies that Larry can not invite up to 6 people.
Hence, the domain can be represented as 0 ≤ p < 6

The population of Chicago, Illinois, in 2003 was 2,869,121. The area of Chicago was 227.1 square miles. What was the average number of people living in 1 square mile?
Answer:
12,633.7
Step-by-step explanation:
population of Chicago, in 2003 = 2,869,121
The area of Chicago = 227.1 square miles.
What was the average number of people living in 1 square mile?
Average number of people living in 1 square mile also refers to the population density of Chicago
Average number of people living in 1 square mile = Total population / total square miles
= 2,869,121 / 227.1
= 12633.734037868

Solve for the variable p Write the equation 4l +26p= 210. Write the equation in the form p = an expression.
Answer:
p = (105-2l)/13
Step-by-step explanation:
4l + 26p = 210
Isolate 26p by subtracting 4l from both sides
26p = 210-4l now divide by 26
p = (210-4l)/26 you can simply
p = (105-2l)/13
