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;

[tex]f^{-1}(x)=\cos^{-1} x+\frac{\pi}{2}[/tex] where [tex]-1\le x\le 1[/tex]

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

Answer:

h ≈ 30.10  ft

Step-by-step explanation:

Marie measures the angle of elevation from a point A to a tree as 34° . She works 10 ft directly towards the tree and discovered the new angle of elevation is 41°. The height of the tree can be computed below.

let

a = distance from point B to the tree

h = height of the tree

The right angle triangle formed from point B,  we can use tan to find the height of the tree.

tan 41°  = opposite /adjacent

tan 41° = h/a

cross multiply

h = a tan 41°

The right angle formed from point A

tan 34° = opposite/adjacent

tan 34° = h/(a + 10)

(a + 10)tan 34° = h

Therefore,

a tan 41° = (a + 10)tan 34°

0.8692867378

a =  0.6745085168(a + 10)

0.8692867378a = 0.6745085168a + 6.7450851684

collect like terms

0.8692867378a - 0.6745085168a = 6.7450851684

0.194778221a = 6.7450851684

a = 6.7450851684/0.194778221

a = 34. 629565532  ft

height of the tree can be find with

h = a tan 41°

h = 34. 629565532 × 0.8692867378

h =  30.103022053  ft

h = 30.10 ft

[tex](x-5)^2 + (y-3)^2= 16[/tex] is the equation of a circle

Step-by-step explanation:

The circle below is centered at the point (5,3) and has a radius of length 4

To find the center  form of equation, we use formula

[tex](x-h)^2 + (y-k)^2= r^2[/tex]

where (h,k) is the center and 'r' is the radius of the circle

given center is (5,3)

h=5  and k =3

radius r= 4, plug in all the values in the equation

[tex](x-h)^2 + (y-k)^2= r^2[/tex]

[tex](x-5)^2 + (y-3)^2= 4^2[/tex]

[tex](x-5)^2 + (y-3)^2= 16[/tex] is the equation of a circle

Answer:

The Answer is C

Step-by-step explanation:

The volume of the cylinder increases by a factor of 25 when the radius is increased by a factor of 5.

The volume of a cylinder is given by the formula:

Volume = π * (radius^2) * height

If the radius is increased by a factor of 5, the new radius is 5 times the original radius. Let's call the original radius "r" and the new radius "5r." The height remains the same.

Now, let's calculate the new volume with the increased radius:

New Volume = π * (5r)^2 * height

New Volume = π * 25r^2 * height

To find the effect on the volume, we can compare the new volume to the original volume:

Effect on Volume = (New Volume) / (Original Volume)

Effect on Volume = (π * 25r^2 * height) / (π * r^2 * height)

The π, height, and r^2 terms cancel out:

Effect on Volume = (25r^2) / (r^2)

Effect on Volume = 25

So, the volume of the cylinder increases by a factor of 25 when the radius is increased by a factor of 5.

Answer:

Total area = 135 .39 square yard

Step-by-step explanation:

Given : composite figure.

To find : Find the surface area of the composite solid. Round the answer to the nearest hundredth.

Solution : We have given a composite figure with rectangle base and four triangles .

Base of two triangle  =  4 yd .

Height of two triangle = √13 yd .

Base of other two triangle  =  6 yd .

Height of other two triangle = 2√2 yd .

Area of rectangle  = length * width .

Area of rectangle  = 6 *4

Area of rectangle  = 24 square yard .

Area of all rectangle = 3 *24 = 72 square yard

Answer:

B.) 45

Step-by-step explanation:

All that is needed to solve this problem is .75*60. Whenever there is a percentage, , just move the decimal place up two :).

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: Domain of definition of a function is the set of numbers which the variable attains and for which the function is defined.

Step-by-step explanation:

f(x) = sqrt (5x-10)

Here x can have value equal to any real number >=2 because if x attains value less that 2, 5x-10 becomes negative and sqrt(5x-10) has no real value.

therefore the domain of the function f(x) is (2, infinity) inclusive of 2.

The domain of the above function is (2, ∞) .

Let y = f(x) be a function with an independent variable x and a dependent variable y.

If a function f provides a way to successfully produce a single value y using for that purpose a value for x then that chosen x-value is said to belong to the domain of f.

For the given function   [tex]y = \sqrt{5x-10[/tex]

The domain will be the value that satisfies the function and produces a value of y

For any value less than 2 , the value of v will be an imaginary number .

As the square root of a negative number will be an imaginary number.

Therefore (2, ∞) is the domain of the above function.

Given that (x,y)=(5,10), we want to find r.

We use the relation:

We substitute x=5 and y=10 into the formula to get,

[tex]r = \sqrt{ {5}^{2} + {10}^{2} } [/tex]

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:

= 72 cm

Step-by-step explanation:

The ratio of lengths of two similar figures is called the linear scale factor.

In this case, the linear scale factor is 2/3

The linear scale factor is also equivalent to the ratio of the perimeter of two similar figures.

Therefore, 2/3 = 48/x

                x = 48 × 3/2

                   = 72 cm

The perimeter of the other polygon is 72 cm

Answer:

72 cm

Step-by-step explanation:

Given in the question, there are two similar polygons and the ratio of the corresponding side lengths is 2/3.

Perimeter of the smaller polygon = 48 cm

let perimeter of the larger polygon = x cm

We know that if two polygons are similar, then the ratio of their perimeters is equal to the ratios of their corresponding side lengths.

So,

Perimeter of smaller polygon / Perimeter of larger polygon = 2 / 3

48 / x = 2 / 3

48(3) = 2(x)

144 = 2x

x = 72 cm

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,
