Answer:
Step-by-step explanation:
a = 2 ; b = 4
4a + 2b² - 2(a -3b) = 4*2 + 2(4)² - 2 (2 - 3*4)
= 4*2 + 2*16 - 2(2 -12)
= 4*2 + 2*16 - 2* (-10)
= 8 + 32 + 20

What is a quadratic function?A polynomial function with one or more variables, where the largest exponent of the variable is two, is referred to as a quadratic function. In other terms, a "polynomial function of degree 2" is a quadratic function.
Given:
A quadratic polynomial,
x² + 10x + 20.
A perfect square trinomial is an expression that may be constructed from the binomial equation's square.
That means, the roots are repeated.
Solving the equation, we get,
x = (-5 ± √5)
The roots are not repeated.
Therefore, it is not a perfect square trinomial.

Step 1: Define
(x - 3)(2x + 1)(3x - 2)
Step 2: Expand
Expand [FOIL]: (2x² + x - 6x - 3)(3x - 2)Combine like terms: (2x² - 5x - 3)(3x - 2)Expand: 6x³ - 15x² - 9x - 4x² + 10x + 6Combine like terms: 6x³ - 19x² + x + 6X^2+3x+4=(x+a)^2+b what is A and B equal please help me
Answer:
a = 1.5, b = 1.75
Step-by-step explanation:
Expand the right side using FOIL, then compare the coefficients of like terms with the expression on the left side.
(x + a)² + b
= x² + 2ax + a² + b , then compare to
x² + 3x + 4
Comparing the coefficients of the x- terms
2a = 3 ( divide both sides by 2 )
a = 1.5
Comparing the constant terms
a² + b = 4
1.5² + b = 4
2.25 + b = 4 ( subtract 2.25 from both sides )
b = 1.75

I will put the answers in the comments I need to use a calculator
Answer:
Step-by-step explanation:
Think of it as two rectangles and one triangle.
The first rectangle is 1.5 * 2.5 = 3.75 square feet.
There is two of these rectangles, so you can do 3.75 *2 = 7.5 square feet.
Finally, the triangle is 1.5 by 1.5, so the area is 1.5 * 1.5 / 2 = 1.125.
To find the total area, add the two together: 7.5 + 1.125 = 8.625 square feet

Answer:

Step-by-step explanation:
$2000 is invested at a rate of 4.2% compounded annually. Identify the compound interest function to model the situation. Then find the balance after 7 years. A = 2000(1.042)^t; $2667.50 A = 2000(1.42)^4t; $2557.50 A = 2000(1.042)^t; $2337.50 A = 2000(14.2)^4t; $2447.50
Answer:
A = 2000(1.042)^t; $2667.50
Step-by-step explanation:
The formula or model for Compound Interest is given as:
A = P(1 + r/n)^nt
Where:
A = Amount or Balance after t years
P = Principal or initial amount invested = $2000
r = Interest rate = 4.2% = 0.042
t = Time in years = 7 years
n = Compounding frequency = Annually = per year = 1
Hence, the compound interest function to model for the situation (Question) with time t above is:
A = 2000(1 + 0.042) ^1 ×t
A = 2000(1.042)^t
Therefore solving for the balance
A = 2000(1.042)^7
A = 2,667.50
A = $2667.50
Therefore, option a =
A = 2000(1.042)^t; $2667.50
is the correct option.

Answer:
Adult tickets sold = 225
Student Tickets sold = 375
Step-by-step explanation:
Let:
Adult tickets sold = x
Student Tickets sold = y
Total tickets sold = 600
So, we can write: x+y = 600
Total money collected = 3037.50
Cost of 1 Adult ticket = $6.00
Cost of one Student ticket = $4.50
So, we can write: 6x+4.5y=3037.50
Now, we get a system of equations, that if solved we can find values of x and y
Let:
[tex]x+y = 600--eq(1)\\6x+4.5y=3037.50--eq(2)[/tex]
We can solve using substitution method.
Finding value of x from eq(1) and putting it in eq(2)
[tex]We\:have\\x+y=600\\x=600-y[/tex]
Put in eq(2)
[tex]6x+4.5y=3037.50\\6(600-y)+4.5y=3037.50\\3600-6y+4.5y=3037.50\\-1.5y=3037.50-3600\\-1.5y=-562.5\\y=\frac{-562.5}{-1.5}\\y=375[/tex]
So, we get value of y = 375
Now put value of y in eq(1) to find value of x
[tex]x+y=600\\Put\:y=375\\x+375=600\\x=600-375\\x=225[/tex]
So, we get value of x = 225
The Tickets sold will be:
Adult tickets sold = x = 225
Student Tickets sold = y = 375
On Monday, I sold 5 small Christmas wreaths and 3 large Christmas wreaths for a total of $82. Let x represent the cost of small wreaths and y represent the cost of large wreaths. Write an equation to represent this situation.
Answer:
The equation is, [tex]5x+3y=82[/tex].
Step-by-step explanation:
Let [tex]x[/tex] represent the cost of small wreaths.
So, the cost of [tex]5[/tex] small Christmas wreaths [tex]=5x[/tex].
Let [tex]y[/tex] represent the cost of large wreaths.
So, the cost of [tex]3[/tex] large Christmas wreaths [tex]=3y[/tex].
On Monday, [tex]5[/tex] small Christmas wreaths and [tex]3[/tex] large Christmas wreaths are sold for a total of [tex]\$82[/tex].
The equation is, [tex]5x+3y=82[/tex].

How can the slope of the line be interpreted? Every 98 words requires 312 minutes to read. Every 312 words requires 98 minutes to read. In each additional minute, approximately 98 more words are read. In each additional minute, approximately 312 more words are read.
Answer:
In each additional minute, approximately 312 more words are read.
Step-by-step explanation:
Given tbe sentences :
The slope is the rate of change per unit: in the context of the question, the number of word reads increases. By 312.
Hence, the slope according to the slope of the graph interpretation is that, the number of words read per minute increases by 312 as the value of minute increases by one minutes.

Step-by-step explanation:
You are in the buy and sell business. find out the wholesale price of an item (e.g. t-shirt, soap,toy) suppose you buy 24 pieces of that item at wholesale price. atleast at what price should you tell each item to have a 25% profit? how much will be your total profit in pesos from these items?
With explanation please!!
The wholesale price isn't given, suppose the wholesale price is $5
Answer:
$6.25 ; 1441.8 pesos
Step-by-step explanation:
Number of items purchased = 24
Wholesale price of item = x
To obtain a 25% profit, the sales price would be :
Wholesale price = wholesale price + 25% of wholesale price
(x = x + 0.25x) per unit
For 24 items :
24x + 0.25 * 24x
Unit wholesale price = 5
24(5) + 0.25*24(5)
= $150
Hence, sale price per unit will be :
$150 / 24
= $6.25
Total profit in pesos :
1 dollar = 48.06 pesos
Total profit = $150 - 24(5) = $150 - $120 = $30
$30 = (30 * 48.06) = 1441.8 pesos
