Answer:
A trinomial is an algebraic equation composed of three terms and is normally of the form a[tex]x^{2}[/tex] + bx + c = 0, where a, b and c are numerical coefficients. The number “a” is called the leading coefficient and is not equal to zero (a≠0). For instance, x² − 4x + 7 and 3x + 4xy – 5y are examples of trinomials.

$0.11
per ounce
1.32/12=0.11!!
Answer: 1.21
Since we know that $1.32 is 12 ounces all we need to do is figure out how much is in each ounce which is "0.11", so this means for each unit equals to "0.11" so
0.11 x 11=1.21 ounces Good luck!
Eric has 240 coins in his collection 11/20 are pennies and 4/40 are nickels
Answer:
There would be 36 coins left
Step-by-step explanation:
I don't know if that was the question but you would do:
11/20x2=22/40
22/40+4/40=26/40
26/40=13/20
One twentieth of 240 is 12

If Sarah sold 20 bags of dog treats for $3.25 each, how much money did she earn? You must show your work to earn full credit.
Answer:
$65
Step-by-step explanation:
20 bags of dog treats multiplied by 3.25 = $65.00
Sarah made 65 dollars.
Answer:
Sarah earned $65.
Step-by-step explanation:
Create an equation.
20 representing the bags she has sold, 3.25 representing the value of each bag. If Sarah sold 20 bags of dog treats, with each of them being worth 3.25, then 20(3.25) = 65, meaning Sarah earned $65.
over the last 4 years michael has earned $240 interest on an initial investment of $2,000. what simple annual interest rate is the bank paying on this account
Answer:
.03 or 3%.
Step-by-step explanation:
Important:
I = interest
P = principal (investment)
R = simple interest rate
T = years
Formula: I = PRT
Given:
I = $240
P = 2000
T = 4 years
R = ?
Plug into formula:
240 = 2000(R)4
Multiply right side 2000*4
240 = 8000R
Divide both sides by 8000.
R = 240/8000
R = .03
The simple annual interest rate was .03 or 3%.
Therefore it .03 or 3%
Which of the following represents a function?
Answer:
B) Graph of an Absolute Value Function
Step-by-step explanation:
A function is a relation in which no two ordered pairs have the same input and different outputs. Whenever you're trying to determine whether a given relation is a function, observe whether each input correspond with exactly one output.
The given table in Option A) is not a function because there are two corresponding y-values for x = 3.
Option C is also not a function because the input value of x = -1 has two output (y-values): -11 and 5.
Option D is also not a function because the input value of 3 has two output values: -5 and 0.
Option B represents a function because each input value has exactly one corresponding output value. A useful technique to use in determining whether a given graph represents a function is the Vertical Line Test. If a vertical line intersects the graph in all places at exactly one point, then the relation is a function.
Attached is an edited screenshot of Option B, where it shows that each blue vertical line has its own corresponding point. This means that the each line crosses the graph at most once. Therefore, the correct answer is Option B.
Answer:
The graph

Just find m2
Answer:
I'll assume the question says "m<1 is 12 deg. more than m<2."
Step-by-step explanation:
m<WXZ is 86
m<1 + m<2 = 86
m<1 = m<2 + 12
(m<2 + 12) + m<2 = 86
2m<2 + 12 = 86
2m<2 = 74
m<2 = 37
m<1 = 49
m<1 + m<2 = 86 [Checks]

Using the discriminant, determine the number of real solutions,
-2x^2+x-28= 0
Ono real solutions
O one real solution
O two real solutions
The number of real solutions is 0, the correct answer is A.
How to use discriminant to find the property of solutions of given quadratic equation?Let the quadratic equation given be of the form ax^2 + bx + c = 0, then
The quantity b^2 - 4ac is called its discriminant.
The solution contains the term [tex]\sqrt{b^2 - 4ac}[/tex] which will be:
Real and distinct if the discriminant is positive
Real and equal if the discriminant is 0
Non-real and distinct roots if the discriminant is negative
There are two roots of a quadratic equations always(assuming existence of complex numbers). We say that the considered quadratic equation has 2 solution if roots are distinct, and have 1 solutions when both roots are same.
We are given that;
The equation -2x^2+x-28= 0
Now,
The discriminant of a quadratic equation ax^2 + bx + c = 0 is given by b^2 - 4ac. The discriminant can be used to determine the number of real solutions of the equation as follows:
If the discriminant is positive, there are two distinct real solutions.
If the discriminant is zero, there is one repeated real solution.
If the discriminant is negative, there are no real solutions.
In this case, the quadratic equation is -2x^2 + x - 28 = 0. Comparing it with the standard form, we can identify that a = -2, b = 1, and c = -28. Therefore, the discriminant is:
b^2 - 4ac
= 1^2 - 4(-2)(-28)
= 1 - 224
= -223
Since, the discriminant is negative, there are no real solutions for this equation.

Answer:
x = 17.331....
Step-by-step explanation:
Basically use Tan on the calculator to find x. Look up "soh cah toa" if you still dont understand what I am doing.
Tan(37) = opposite / adjacent = x / 23
x = Tan(37) (23) multiply by 23 on both sides to get this
x = 0.753.... (23) now multiply the tan value on the calculator
x = 17.331....

Please show step by step :)
Answer:

Step-by-step explanation:
f(9) = - 14 maps x = 9 to y = - 14
The inverse maps y = - 14 to x = 9 , that is

find the sum of the even integers from 20 to 50.
with solutions please help
Answer: 560
Step-by-step explanation:
There are [20, 22, 24, 26, 28]: 5 even integers for each ten numbers.
The 20's set can be written as 5*20 + (2+4 + 6 + 8) = 5*20 + (20) = 120
The 30's can be written: 5*30 + 20 = 170
40's: 5*40+20 = 220
50's: 5*50+20 = 270
60's: 5*60+20 = 320
Each set is incremented by 50
We want the sets for 20, 30, and 40, plus the number 50.
(120+170+220+50) = 560
You can also do this in Excel (attached). Set the first cell to 20, the next cell below equal to the cell above plus 2. Then draw the second cell down until you've reached 50. Then sum the cells to arrive at 560.
