The basketball team sold t-shirts and hats as a fundraiser they sold a total of 23 items and made a profit of $246 they made a profit of $10 for every t shirt they sold and $12 for every hat they sold dertermine the number of t shirts and the number of hats the basketball team sold
The basketball team sold a total of 23 items (t-shirts and hats) and made $246. By setting up and solving a system of equations, it was determined that they sold 15 t-shirts and 8 hats.
To determine the number of t-shirts and hats sold by a basketball team for a fundraiser, given that they sold a total of 23 items and made a profit of $246, with a profit of $10 per t-shirt and $12 per hat sold. To solve this problem, we can set up a system of linear equations and solve for the two variables representing the number of t-shirts (T) and the number of hats (H).
Let T represent the number of t-shirts and H represent the number of hats.
We know that T + H = 23 (since 23 items were sold in total).
We also know that the profit from t-shirts is $10 per t-shirt, and the profit from hats is $12 per hat. Therefore, 10T + 12H = $246 (total profit).
We can now set up the equations:
T + H = 23
10T + 12H = $246
From the first equation, we can express H in terms of T: H = 23 - T.
Substitute H = 23 - T into the second equation:
10T + 12(23 - T) = $246
Simplify and solve for T:
10T + 276 - 12T = $246
-2T + 276 = $246
-2T = $246 - 276
-2T = -$30
T = 15 (number of t-shirts sold)
Now, we can find the number of hats by substituting T back into H = 23 - T. Since T is 15, H = 23 - 15 = 8 (number of hats sold).
Therefore, the basketball team sold 15 t-shirts and 8 hats.

Answer:
[tex]x^{\frac{5}{12} }[/tex]
Step-by-step explanation:
In the question given we use the law of exponents;
[tex](a^{b})^{c} = a^{bc}[/tex]
If a base a is raised to a power b and the entire expression raised to a power c, the resulting expression is simply equal to the base a raised to the product of the two exponents b and c, that is bc.
In the case given,
a = x
b = 5/8
c = 2/3
To simplify the expression we simply multiply b and c;
bc = 5/8 * 2/3
= 5/12
The simplified expression is thus;
[tex]x^{\frac{5}{12} }[/tex]

The correct answer is ((x⁵/⁸)²/³) = x⁵/¹²
Step-by-step explanation:
Points to remember:-
Identity
(xᵃ)ᵇ = xᵃᵇ
Here it is given that, ((x⁵/⁸)²/³)
To find the value of ((x⁵/⁸)²/³)
(5/8) * (2/3) = (5 * 2) /(8 * 3) = 10/24 = 5/12
By using identity (xᵃ)ᵇ = xᵃᵇ we can write,
((x⁵/⁸)²/³) = x⁽⁵/⁸⁾ˣ⁽²/³⁾
= x⁵/¹²
Therefore the correct answer is ((x⁵/⁸)²/³) = x⁵/¹²

A parabola opening upward shifted 7 units rights and 4 units down
Answer:
y + 4 = a(x - 7)^2
Step-by-step explanation:
The standard vertex form of a parabola with vertex at (h, k) is
y - k = a(x - h)^2
and if we start with the simplest case, y = a(x)^2 and translate its graph 7 units to the right and 4 units down, we get y - {-4] = a(x - 7)^2, or
y + 4 = a(x - 7)^2
The answer is y + 4 = a(x - 7)^2.
The standard vertex form of a parabola with vertex at (h, k) is
y - k = a(x - h)^2
And if we start with the simplest case,
y = a(x)^2 and
translate it Into 7 units to the right and 4 units down,
we get
y - {-4] = a(x - 7)^2
then we get the equation is y + 4 = a(x - 7)^2.

what is the inverse of y=cos(x-pi/2)
Answer:
[tex]f^{-1}(x)=\cos^{-1} x+\frac{\pi}{2}[/tex]
Step-by-step explanation:
The given function is
[tex]y=\cos(x-\frac{\pi}{2})[/tex]
To find the inverse of this function, we interchange x and y.
[tex]x=\cos(y-\frac{\pi}{2})[/tex]
Take the inverse cosine of both sides to obtain;
[tex]\cos^{-1} x=y-\frac{\pi}{2}[/tex]
[tex]\cos^{-1} x+\frac{\pi}{2}=y[/tex]
Therefore the inverse of the given cosine function is;

Answer: Option B
[tex]f(g(x)) = 4x^2 -41x + 105[/tex]
Step-by-step explanation:
We have 2 functions
[tex]f(x) = 4x -\sqrt{x}[/tex]
[tex]g(x) = (x-5)^2[/tex]
We must find [tex]f(g(x))[/tex]
To find this composite function enter the function g(x) within the function f(x) as follows
[tex]f(g(x)) = 4(g(x)) -\sqrt{(g(x))}[/tex]
[tex]f(g(x)) = 4(x-5)^2 -\sqrt{(x-5)^2}[/tex]
By definition [tex]\sqrt{a^2} = |a|[/tex]
So
[tex]f(g(x)) = 4(x-5)^2 -|x-5|[/tex]
Since x is greater than 5 then the expression [tex](x-5)> 0[/tex].
Therefore we can eliminate the absolute value bars
[tex]f(g(x)) = 4(x-5)^2 -(x-5)[/tex]
[tex]f(g(x)) = 4(x^2 -10x + 25) -(x-5)[/tex]
[tex]f(g(x)) = 4x^2 -40x + 100 -x+5[/tex]
[tex]f(g(x)) = 4x^2 -41x + 105[/tex]

C.
The table represents a geometric sequence because the successive y-values have a common ratio of 0.4.
D.
The table represents an arithmetic sequence because the successive y-values have a common difference of 4.2.
Answer:
A.
The table represents a geometric sequence because the successive y-values have a common ratio of -2.4.
Step-by-step explanation:
A geometric sequence, with a first term a and common ratio r, is generally represented as;
[tex]a,ar,ar^{2},ar^{3},ar^{4},............ar^{n}[/tex]
The first term refers to the first number that appears in the sequence. The common ratio is the constant that multiplies a preceding value to obtain the successive one. That is, to obtain [tex]ar^{2}[/tex] from [tex]ar[/tex] we multiply [tex]ar[/tex] by the common ratio r.
In the table given the y-values are as follows;
4, -9.6, 23.04, -55.296
To obtain the common ratio we simply divide each value by the preceding one;
(-9.6)/4 = -2.4
23.04/(-9.6) = -2.4
(-55.296)/23.04 = -2.4
Since the sequence of numbers has a common ratio then it qualifies to be a geometric sequence. Thus, the table represents a geometric sequence because the successive y-values have a common ratio of -2.4.
Answer:
The table represents a geometric sequence because the successive y-values have a common ratio of -2.4

Compare the three functions below. Which has a greater period? A) y = 3cos(2x+1), B) y=5cos(4x +8), and C) y=cos(2x+4) (4.3)
Comparing the periods of the given cosine functions indicates that functions A) and C) both have the greatest period of π, which is longer than the period of function B), π/2.
Explanation:To compare the periods of the given functions, let's first understand what the general form of a cosine function tells us about its period.
The general form is y = A cos(Bx + C), where A is the amplitude, B affects the period, and C is the phase shift.
The period of such a function is given by 2π / |B|.
For function A) y = 3cos(2x+1), B = 2, thus its period is π.
For function B) y=5cos(4x +8), B = 4, yielding a period of π/2.
Lastly, for function C) y=cos(2x+4) (4.3), assuming the (4.3) is an unrelated notation and focusing on the given cos component with B = 2, its period is also π.
The function with the greatest period among A, B, and C is thus A) and C), both having the same period of π, which is greater than the period of B).
