Swimming Pool On a certain hot summer's day, 366 people used the public swimming pool. The
daily prices are $1.25 for children and $2.25 for adults. The receipts for admission totaled $767.50.
How many children and how many adults swam at the public pool that day? There were
children at the public pool.
Answer:
c=__ and a=__
Step-by-step explanation:
767.50=1.25(c)+2.25(a).
366=c+a
normally from here, I would just guess the number of adults and children. It does take a while doing it that way, but maybe you know a quicker way. Hope this helps :)

Find f(4) given f(x) = 2x^2 - 7
Answer:
f(4) = 25
Step-by-step explanation:
substitute x = 4 into f(x)
f(4) = 2(4)² - 7 = 2(16) - 7 = 32 - 7 = 25
19. Solve for the angle x.
sin²(2x) = 1
Answer: Е
Step-by-step explanation:
▪︎ a^2 - b^2 = (a-b)(a+b)
sin^2(2x) = 1
sin^2(2x) - 1 = 0
(sin2x - 1)(sin2x + 1) = 0
sin2x - 1 = 0 or sin2x + 1 = 0
sin2x - 1 = 0
sin2x = 1
2x = 90° + 360°n
x = 45° + 180°n
▪︎180° means half of the unit circle, therefore,
x = 45° + 360°n and
x = 45° + 180° + 360°n = 225° + 360°n
sin2x + 1 = 0
sin2x = -1
2x = 270° + 360°n
x = 135° + 180°n
therefore,
x = 135° + 360°n and
x = 135° + 180° + 360°n = 315° + 360°n
n is an integer

[tex]\huge\boxed{\bf\:tan \: Z= \frac{4}{3}}[/tex]
Step-by-step explanation:
We know that, tan θ = opposite side of ∠θ / adjacent side of ∠θ.
Here, we need to find tan Z,
In this triangle for ∠Z,
Opposite side = 28Adjacent side = 21Then,
tan Z
= opposite side / adjacent side
= 28 / 21
= 4 / 3

The graph of a sinusoidal function intersects its midline at (0, 1) and then has a maximum point at
Write the formula of the function, where is entered in radians.
f(x) =
Answer:
f(x) = 4·sin(2/7x) +1
Step-by-step explanation:
The sinusoidal function y = a·sin(kx) +b will have cross its midline at (0, b), and a peak value of (x, y) = (π/(2k), a+b). We can use these facts to find the values of a, k, and b for the sinusoidal function.
__
midline(0, b) = (0, 1) ⇒ b = 1
peak value(7π/4, 5) = (π/(2k), a+1)
This gives rise to two equations:
7π/4 = π/(2k)
k = π/(2(7π/4)) = 2/7
and
a+1 = 5
a = 4
equationUsing the found values for the parameters of the function, we have ...
f(x) = 4·sin(2/7x) +1
Please help me solve for Z
The correct value of z in this figure is 190⁰
The image given in this question is of a circle. To solve it, let's calculate it as an equation of the first degree.
– First, let's: add the data that are on the circle and equate the equality as 360⁰, which is the value of the degree of a circle.
145 + 24 + z = 360⁰
– Now, let's: add the natural terms to each other. And finally, we'll isolate z and subtract 360⁰ by the number that's left.
145 + 24 + z = 360⁰
170 + z = 360⁰
z = 360⁰ - 170
z = 190⁰
So, the value of z, will be 190⁰

what is an isosceles triangle?An isosceles triangle is a type of triangle with base angles equal and opposite sides equal.
Analysis:
Since GF = EF
∠FGE = ∠FEG = (x - 18)°( base angles of an isosceles triangle are equal)
∠FGE + ∠FEG + ∠GFE = 180°( sum of angles in a triangle)
(x - 18)° + (x-18)° + 66 = 180
2x -36 + 66 = 180°
2x + 30 = 150
2x = 180 - 30
2x = 150°
x = 150/2 = 75°
In conclusion, the value of x in the diagram is 75°

What is the common difference between successive terms in the sequence? 2, 8, 14, 20, 26,. –6 –4 4 6.
Answer:
The common difference is the difference between any two consecutive terms in an arithmetic sequence.
The formula which is used to find the common difference in AP is
d = an - an-1
Here the common difference is
d = a2 - a1 = 8 - 2 = 6
d = a3 - a2 = 14 - 8 = 6
d = a4 - a3 = 20 - 14 = 6
d = a5 - a4 = 26 - 20 = 6
2, 8, 14, 20, 26 … = 2, (2 + 6), (8 + 6), (14 + 6), (20+ 6) …
Therefore, the common difference is 6.

Find the sum of the first 200 terms of the arithmetic sequence that begins: 12, 18, 24, ...
Answer:
S₂₀₀ = 121800
Step-by-step explanation:
the sum to n term of an arithmetic sequence is
[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] [ 2a₁ + (n - 1)d ]
where a₁ is the first term and d the common difference
here a₁ = 12 and d = a₂ - a₁ = 18 - 12 = 6 , then
S₂₀₀ = [tex]\frac{200}{2}[/tex] [ (2 × 12) + (199 × 6) ]
= 100(24 + 1194)
= 100 ×1218
= 121800
