Answer:

The radius is [tex]r=5\ cm[/tex]

Step-by-step explanation:

we know that

The inscribed angle is half that of the arc it comprises.

so

[tex]m<C =(1/2)[arc\ AB][/tex]

[tex]m<C =90\°[/tex]

substitute

[tex]90\°=(1/2)[arc\ AB][/tex]

[tex]arc\ AB=180\°[/tex]

That means----> The length side AB of the inscribed triangle is a diameter of the circle

Applying Pythagoras Theorem

Calculate the length side AB

[tex]AB^{2}=AC^{2}+BC^{2}[/tex]

[tex]AB^{2}=8^{2}+6^{2}[/tex]

[tex]AB^{2}=100[/tex]

[tex]AB=10\ cm[/tex] -----> is the diameter

Find the radius

[tex]r=10/2=5\ cm[/tex] -----> the radius is half the diameter

20^2+21^2=29^2 can be used to determine if the triangle is a right triangle

Answer:

Step-by-step explanation:

The two smaller line lengths are squared separately and added. The square of the third line is noted. If squares of the two small ones equal the square of the largest one, you are working with a right angle triangle.

The one that puts into a formula what is stated above is B. D is close, but the longest line must be by itself.

Perpendicular lines are lines that touch each other, or are slanted in a way that they will eventually touch each other. The examples I used are all crosses, which are two line that cross.

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.

The formula for finding the volume of a rectangular prism (the cargo area of the truck is the shape of a rectangle in 3D; a rectangular prism) is V = (l)(w)(h); where l = length, w = width, and h = height.

First, substitute the known values into the equation:

l = 8.5

w = 6

h = 10.5

V = (8.5)(6)(10.5)

(Note: .5 = 1/2)

Now, all we need to do is simplify:

V = 535.5 ft³ OR 535 1/2 ft³

(Note: ft³ is the condensed form of cubic feet)

You can pick whichever form your test directs you to use. They are both the same value though.

Hope this helps!

The volume of the cargo area of the truck is 519.75 cubic feet.

The volume of the cargo area of the truck can be calculated by multiplying its length, width, and height. Given the dimensions in feet are:

Length = 8 1/2 feet = 8.5 feet = 8 + 1/2 feet

Width = 6 feet

Height = 10 1/2 feet = 10.5 feet = 10 + 1/2 feet

To find the volume, we convert the mixed numbers to improper fractions and then multiply:

Length in fractions = 8 + 1/2 = 17/2 feet

Width in fractions = 6 = 6 * 2/2 = 12/2 feet

Height in fractions = 10 + 1/2 = 21/2 feet

Now, multiply the dimensions to find the volume:

Volume = Length * Width * Height

Volume = (17/2 feet) * (12/2 feet) * (21/2 feet)

Volume = (17 * 12 * 21) / (2 * 2 * 2) cubic feet

Volume = 4158 / 8 cubic feet

Simplifying the fraction, we get:

Volume = 519.75 cubic feet

Answer:

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]

The answer is -2. X is -2.

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.

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).

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.

Answer:

[tex]f(x)=log_ex[/tex]

Step-by-step explanation:

By definition, we can write ln instead of log. WHEN??

Whenever the base of the logarithm is the number "e".

Hence, when we have:

[tex]Log_e[/tex]

We can write it in shortcut as:

[tex]Log_e=ln[/tex]

Hence, ln x can also be written as [tex]Log_ex[/tex]

Fourth answer choice is right.

Answer:

[tex]f(x) = log_e(x)[/tex]

Step-by-step explanation:

[tex]f(x) = ln x[/tex]

For logarithmic function ln(x) the base of ln is 'e'

[tex]f(x) = log_3(x)[/tex]

The base of log is 3 . so it is not equivalent to [tex]f(x) = lnx[/tex]

[tex]f(x) = log_{10}(x)[/tex]

The base of log is 10 . so it is not equivalent to [tex]f(x) = lnx[/tex]

[tex]f(x) = log_b(x)[/tex]

The base of log is b . so it is not equivalent to [tex]f(x) = lnx[/tex]

[tex]f(x) = log_e(x)[/tex]

The base of log is e . so it is equivalent to [tex]f(x) = lnx[/tex]

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]

Answer:

The correct answer is ((x⁵/⁸)²/³) = x⁵/¹²

Step-by-step explanation:

Points to remember:-

Identity

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,
