Answer:
$10.88
Step-by-step explanation:
To find the selling price, we first have to find the markup price by multiplying 8 by 36 and then dividing the product by 100.
8 × 36 = 288288 ÷ 100 = 2.88Now, we add the markup price the cost of the book.
2.88 + 8 = $10.88.Therefore, the selling price is $10.88.

Write the discriminant of quadratic equation ax2+bx+c=0
Hi!
In any quadratic in the form you have given ([tex]ax^2+bx+c=0[/tex]), the discriminant is ALWAYS
[tex]b^2-4ac[/tex]
Given the quadratic formula:
[tex]x=\frac{-b+/-\sqrt{b^2-4ac} }{2a}[/tex]
-------------------------------------------------------------------------------------------------------------
The discriminant would be the part of the equation that is under the square root.
-------------------------------------------------------------------------------------------------------------
Therefore, your answer is [tex]b^2-4ac[/tex]
Solve the equation by factoring.

PLEASE HELP ILL MARK BRAINLIEST
Answer:
y = 128(4.926)^x
Step-by-step explanation:
Exponential function: y = ab^x
x = 0, y = 128
128 = ab^0
128 = a
--------------------
a = 128, y = 371,293, x = 5
371,293 = 128 x b^5
b^5 = ( 371,293 / 128 )
b = (fifth root) 5^√2900.7265625
b ≈ 4.926
----------------------------------------
y = 128(4.926)^x

If the area of square 3 is 80 cm^2 and the area of square 2 is 100 cm^2, what is the area of square 1? HELP ASAP
Answer:
180 sq cm
Step-by-step explanation:
Square 1 formed on hypotenuse of the triangle, squares 2 and 3 are formed on the perpendicular legs of the triangle. Thus, by Pythagoras Theorem, A(square 1) will be equal to the sum of the areas of (square 2) and (square 3).
[tex]\implies A(square \:1) =A(square \:2)+A(square \:3) \\ \\ \implies \: A(square \:1) =100 + 80\\ \\ \implies \: A(square \:1) =180 \: {cm}^{2} [/tex]

Solve these 2 Question. 50 Points + Brainelist
using simultaneous equation:
2x + 3y = 190
3x + y = 180 * 3
Then:
2x + 3y = 190
9x + 3y = 540
--------------------
-7x = -350
x = 50
Insert this in equation 1 to find value of y:
2x + 3y = 190
2(50) + 3y = 190
3y = 190 - 100
3y = 90
y = 30
expanding the following:
→ (x + 2)³
[tex]\sf apply \ cubic \ formula : \bold{\left(a+b\right)^3=a^3+3a^2b+3ab^2+b^3}[/tex]
[tex]\rightarrow \sf x^3+3x^2\cdot \:2+3x\cdot \:2^2+2^3[/tex]
[tex]\rightarrow \sf x^3+6x^2+12x+8[/tex]
Justify for x = 5
[tex]\rightarrow \sf (5)^3+6(5)^2+12(5)+8[/tex]
[tex]\rightarrow \sf 125+150+60+8[/tex]
[tex]\rightarrow \sf 343[/tex]
Answer:
(a) x=50 y=30Step-by-step explanation for (a):
First use system of equations. Isolate a variable and substitute.
2x + 3y = 190
3x + y = 180
Isolate
subtract 3x from both sides of the second equation
y = 180 - 3x
since 180 - 3x = y, you can substitute this into the first equation for y
Substitute
2x + 3y = 190
2x + 3(180 - 3x) = 190
Distribute the 3
2x + (540 - 9x) = 190
Solve for x
subtract 540 from both sides
2x - 9x = -350
simplify
-7x = -350
divide each side by -7
x = 50
But you still need to solve for y, so substitute the x back into the first equation.(But really you could use either equation)
2(50) + 3y = 190
subtract 100 (2 * 50) from both sides
3y = 90
y = 30
Check your work by resubstituting.
3(50) + 30 = 180.
(b) This one is weird.
(x + 2)^3 expands to (x + 2)(x + 2)(x + 2).(Remember, it is NOT (x^3 + 8), you don't "distribute" the exponent)
It then simplifies to x^3 + 6x^2 + 12x + 8, and x = 5 is NOT an answer here. Maybe there is something more that you might not have screenshotted?
*edit its not asking to prove x is a solution(which i thought lolllll) its asking to plug x = 5 into the equation*

Mrs. Galicia gave her sisters $3000 each to invest. The investment will last 8 years. The table shows what each sister did with their investment and how it changed over 8 years. Use the chart to answer the following questions please
1. What is the balance of Michelle's $3000 after 8 years?
2. What is the balance of Kristen's $3000 after 8 years?
3. What is the balance of Gabriella's $3000 after 8 years?
4. What is the balance of Judy's $3000 after 8 years?
5. Who has the most money at the end of the 8 years? If i were to choose one of the options to use for my own money, which option should I choose?
Michelle's balance after 8 years is $10,790.48.
Kristen's balance after 8 years is $3,770.55.
Gabriella's balance after 8 years is $24,780.42.
Judy's balance after 8 years is $3618.62.
The person with the most money at the end of the 8 years is Gabriella. If I were to choose one of the options, I would choose Gabriella's option
What is Michelle's balance after 8 years?The formula that can be used to determine the future value of an amount with compounding is:
FV = P (1 + r)^nm
Where:
FV = Future value P = Present value R = interest rate / number of compoundingm = number of compoundingN = number of yearsFuture value with monthly compounding = $2000 x ( 1 + 0.035/12)^(12 x 8) = $2645.18
Future value with continuous compounding = : A x e^r x N
A= amount e = 2.7182818 N = number of years r = interest rate1000 x e^0.018 x 8 = $8,145.30
Total = $8,145.30 + $2645.18 = $10,790.48
What is Kristen's balance after 8 years?Future value with quarterly compounding = 2500 x (1 + 0.012 / 4)^(4 x 8) = $2,751.50
Future value with quarterly compounding = 500 (1 .0225)^(8x4) = $1019.05
Total = $3,770.55
What is Gabriella's balance after 8 years?$3000 x e^0.032 x 8 = $24,780.42
What is Judy's balance after 8 years?Future value with exponential increase = 1050 x (1.015)^8 = $1,182.82
Future value with biannual compounding = 1950 x (1 + 0.028/2)^(8 x 2) = $2435.80
Total = $3618.62

Answer:
6
Step-by-step explanation:
1/2 of 12 is 6
Zeke ate twice as much as Niko, so he ate 12 and Niko ate 6.
This makes 18 cookies eaten in total.
NO LINKS. Part 1: Complete the sequence
Answer:
a) (6, 6) and (7, 4)
b) [tex]t(n)=-2n+18[/tex]
c) see attached
Step-by-step explanation:
From inspection of the table, we can see that as n increases by 2, t(n) decreases by 4. Therefore, as this a directly proportional relationship, it is a linear function.
So as n increases by 1, t(n) will decrease by 2.
Therefore, the remaining two ordered pairs are:
(6, 6)
(7, 4)
We know that the function decreases by 2 each time n increases by 1, so the slope (gradient) of the linear function will be -2.
Using the point-slope formula: [tex]y-y_1=m(x-x_1)[/tex]
(where [tex]m[/tex] is the slope and [tex](x_1,y_1)[/tex] is a point on the line)
Given:
[tex]m=-2[/tex][tex](x_1,y_1)=(1,16)[/tex][tex]\implies y-16=-2(x-1)[/tex]
[tex]\implies y=-2x+18[/tex]
[tex]\implies t(n)=-2n+18[/tex]
Graphing
To find the y-intercept, substitute [tex]n=0[/tex] into the equation:
[tex]\implies t(0)=-2(0)+18=18[/tex]
Therefore, the y-intercept is (0, 18)
To find where the line crosses the x-axis, set the equation to zero and solve for n:
[tex]\implies -2n+18=0[/tex]
[tex]\implies 2n=18[/tex]
[tex]\implies n=9[/tex]
Therefore, the line crosses the x-axis at (9, 0)
