Find the zeros of f(x) =x^3+2x^2-3x
Answer: 0, 1, -3
Step-by-step explanation:
f(x) = x^3 +2x^2 -3x
f(x) = x(x^2 +2x-3)
f(x) = x(x-1)(x+3)
to find zeroes, plug into f(x) and solve for each value of x. doing this gives 0, 1, and -3

The number of employees per department are normally distributed with a population standard deviation of 198 employees and an unknown population mean. If a random sample of 22 departments is taken and results in a sample mean of 1460 employees, find the error bound (EBM) of the confidence interval with a 80% confidence level.
Answer:
EBM = +-54.126
Step-by-step explanation:
In this question we have confidence interval to be 80%
The formula to solve this is in the attachment.
Bar X = 1460
Z-alpha/2 = 1.282
Sd = standard deviation = 198 employees
n = 22 departments
After we have inserted all values in to the formula we have:
1460 +-(1.282*198/√22)
= 1460+-(54.12604)
= (1405.87, 1514.126)
The error bounded mean EBM
= +-z-alpha/2 x (sd/√n)
= 1.282 x 198/√22
= 1.282 x 42.22
EBM = +-54.126

Step-by-step explanation:
The polynomial p is a function of x. The graph of p has four zeros at -4, -2/3, 0, and 9
Select all the expression that could represent p.
A
-3x(x + 4)(3x + 2)(x - 9)
B
3x(x – 4) (x + 3)(x +9)
с
3x(x + 4)(2x - 3)(x -9)
D
- x(x + 4) (x + })(x – 9)
E
-3x(x + 4)(3x + 2)(x - 9)2
The only expression of that can represent polynomial p as a function on a graph having four zeros at -4, -2/3, 0, and 9 is: A. [tex]\mathbf{-3x(x + 4)(3x + 2)(x - 9)}[/tex]
Given the four zeros of the graph of p are at:
-4, -2/3, 0, and 9From the options given, the expression in option A will represent a function of a polynomial p with zeros at -4, -2/3, 0, and 9.
Here's why:
[tex]-3x(x + 4)(3x + 2)(x - 9)[/tex] (option A)
Therefore are four factors in the polynomial above which are:
[tex]3x\\\\(x + 4)\\\\(2x - 3), $ and\\\\(x -9)[/tex]
The zeros of polynomial p will be the following:
[tex]3x = 0\\\\x = \frac{0}{3} \\\\\mathbf{x = 0}[/tex]
[tex](x + 4) = 0\\\\\mathbf{x = -4}[/tex]
[tex](3x + 2) = 0\\\\3x = -2\\\\\mathbf{x =-\frac{2}{3}}[/tex]
[tex](x -9) = 0\\\\\mathbf{x = 9}[/tex]
Therefore, the only expression of that can represent polynomial p as a function on a graph having four zeros at -4, -2/3, 0, and 9 is: A. [tex]\mathbf{-3x(x + 4)(3x + 2)(x - 9)}[/tex]

Answer:
The answer to this problem is B, C, and E.
Step-by-step explanation:
The true equations are B. 2x+4y=20 and C. x+6y=10
How to determine the equations?The point is given as (10,0)
This means that:
x = 10 and y = 0
Next, we test the options by substituting the above values.
So, we have:
A. 5x+2y = 15
5(10) + 2(0) = 15
50 = 15 ---- false
B. 2x+4y = 20
2(10) + 4(0) = 20
20 = 20 ---- true
C. x+6y=10
10 + 6(0) = 10
10 = 10 ---- true
D. 3x+3y=13
3(10) + 3(0) = 13
30 = 13 ---- false
E. 4x+2y=20
4(10) + 2(0) = 20
40 = 20 ---- false
F. 6x+y=50
6(10) + 0 = 50
60 = 50 ---- false
Hence, the true equations are B. 2x+4y=20 and C. x+6y=10

Answer:
The value of x would 12.2.

One-third of a number t is equal to 7.
Write the word sentence as an equation then solve
Answer:
21
Step-by-step explanation:
One third of the number can be represented by 1/3t.
To make an equation, set this equal to 7.
1/3t = 7
Then, solve for t by dividing each side by 1/3:
1/3t = 7
t = 21
So, the number is 21.

What is the greatest possible error if Irina measured the weight of her dog as 13 pounds?
Answer:
0.5
Step-by-step explanation:
Given that:
Irina measured the weight of her dog to be 13 pounds.
The greatest possible error that could have to occur will be the maximum error.
Let assume that the 13th value obtained was rounded between the range of 12.5 → 13.49 to 13 pounds
Then;
The greatest possible error that could have to occur = 13.0 - 12.5 pounds
The greatest possible error that could have to occur = 0.5 pounds

18.53 ft2
43.07 ft2
39.53 ft2
20.07 ft2
Answer:
B) 176 ft²
Step-by-step explanation:
Answer:
39.53 ft2
Step-by-step explanation:
If you are having a hard time with this it is most likely due to the semicircle. First you need to divide the diameter (3) by 1/2, next you multiply the now radius (radius is always 1/2 of the diameter) and pi to get 3.53.
Now you have to find the area of the rectangle, 3*12 = 36.
36 + 3.53 = 39.53 rounded.
The entrance for the amusement park is $40, visitors purchase additional $2
tickets for rides, games and food. How many tickets can you buy if you
brought $100 to spend at the park?
Answer:
2 tickets because round
Step-by-step explanation:
make an equation: 100=40x+2 and solve
2.45 tickets so only two
40+40 =80
100-80=20
but 100-2=98 so there is only 18$ left so not enough for another ticket
Answer:
30 Tickets
Step-by-step explanation:
In the question, it said that $40 is the entrance fee. Then, it said that visitors purchase additional tickets for rides, games, and food. This means that EACH ticket is 2 dollars.
Hence, $40 (entrance fee) + $2 (each ticket price) x (the number of tickets spent) = 100 (total amount of money).
So, the equation should be 40 + 2x = 100, which means x = 30.
100 - 40 = 60
60/2 = 30
30 tickets can be purchased
