Answer:
(A, B, C) = (2, 5, 2)
Step-by-step explanation:
Undo the square operation by taking the square root. Both the positive and negative square roots are solutions to the equation.
[tex]c -2 = \pm\sqrt{50}[/tex]
Add 2 to both sides of the equation:
[tex]c = 2\pm\sqrt{50}[/tex]
Simplify the square root:
[tex]c=2\pm\sqrt{25\cdot2}=2\pm\sqrt{25}\cdot\sqrt{2}\\\\\boxed{c=2\pm5\sqrt{2}}\qquad\text{A=2, B=5, C=2}[/tex]
_____
Additional comment
Square roots are simplified by factoring out the factors that are perfect squares.

Jim bought some nice running shoes for $216. The sales
tax is 6.5% and he is paying cash with bills only because
he doesn't have any change. What is the least amount
he should give the cashier?
Answers
Answer:
I believe the answer is $ 231.00.
Step-by-step explanation:
I might be wrong, but please don't hate me if I am!!
First I found the sales tax of the nice running shoes by multiplying the price of the shoes by the sales tax:
216 * 6.5% = 14.04
Then I added the sales tax to the price of the nice running shoes:
$ 216 + $ 14.04 = $ 230.04
Since Jim doesn't have any change and can only pay in cash, you would round $ 230.04 to the nearest dollar:
$ 230.04 is rounded to $ 231.00 :D

Hello, for the first question, you just take the person with the largest number and the person with the smallest number. Kenny (5) and Sammy (0).
For question 18, you just add up all the numbers like this:
0+1+3+5+4+1+1+2+1= 18
And then you divide it by the number of people there which is 9:
18/9=2
For question 19, you arrange all the numbers from least to greatest like this:
0,1,1,1,1,2,3,4,5
And then you count on both ends until it meets the middle. 1 is the middle.
For the last question, you just find the number that appears the most, which is one.
Consider the functions shown on the graph. A coordinate grid with two lines. One line labeled f(x) and passes through (negative 3, 1), (0, 1), and point (1.5, 1). The second line is labeled g(x) and passes through point (0, negative 1), point (1.5, 1), and point (3, 3). What is the best approximation for the input value when f(x)=g(x)?

Answer:
1.8
Step-by-step explanation:
If we know Xin ordered 5 identical pieces of bread, this must mean that each one weighs the same
By dividing the 9 pounds with 5 (the amount of bread) we will get 1.8
So each bread is 1.8
but if u want to check the answer then we can multiply 1.8 with the 5 loaves of bread and it will result in 9

trig function
a. Cos Ɵ = 2/5 find Tan Ɵ
b. Cosec Ɵ = 7/3 find Cos Ɵ
c. Cot Ɵ = 4/3 find Sec Ɵ
d. Tan Ɵ = 3 find Cosec Ɵ
Answers
Answer:
a.
cos θ = 2/5, tan θ = ?
tan θ = sin θ / cos θ tan θ = √sin² θ / (2/5) tan θ= 5√(1 - cos²θ) / 2 tan θ = 5√(1 - 4/25) / 2 tan θ = 5√(21/25) / 2 tan θ = √21 / 2b.
cosec θ = 7/3, cos θ = ?
cosec θ = 1/ sin θ cosec θ = 1/ √(1 - cos²θ) √(1 - cos²θ) = 1 / cosec θ1 - cos²θ = (1 / (7/3))² cos²θ = 1 - 9 / 49cos²θ = 40/49cos θ = √40/49cos θ = 2√10/7c.
cot θ = 4/3, sec θ = ?
cot θ = cos θ / sin θcos θ = cot θ * sin θcos θ = 4/3 * √(1 - cos²θ)9cos²θ = 16(1 - cos²θ)25cos²θ = 16cos²θ = 16/25cos θ √16/25cos θ = 4/5sec θ = 1/ cos θsec θ = 1/ (4/5)sec θ = 5/4d.
tan θ = 3, cosec θ = ?
sin²θ + cos²θ = 11 + cos²θ/sin²θ = 1/ sin²θ1 + 1/tan²θ = cosec²θ1 + 1/9 = cosec²θcosec²θ = 10/9cosec θ = √(10/9)cosec θ = √10 / 3What is the angle of rotation of the image?

3. The Manhattan Island Cruise Company sold 57
tickets for its Circle-the-Island Cruise. Each adult had
to pay $22 for the cruise and each child had to pay
$10. The company's total receipts were $774. How
many children went on the cruise?
Answers
Answer:
40 children went on the cruise.
Step-by-step explanation:
This question can be solved by a system of equations.
I am going to say that:
x is the number of adults on the cruise
y is the number of children on the cruise.
57 tickets were sold:
This means that [tex]x + y = 57[/tex], and since we want the number of children y, [tex]x = 57 - y[/tex]
Each adult had to pay $22 for the cruise and each child had to pay $10. The company's total receipts were $774.
This means that:
[tex]22x + 10y = 774[/tex]
Since [tex]x = 57 - y[/tex]
[tex]22(57 - y) + 10y = 774[/tex]
[tex]1254 - 22y + 10y = 774[/tex]
[tex]12y = 480[/tex]
[tex]y = \frac{480}{12}[/tex]
[tex]y = 40[/tex]
40 children went on the cruise.
