Step-by-step explanation:

F-¹ (x)

f-¹=x-7

fx=7+1

Fx = 8 is the answer

Given: f(x) = x - 7

(a)

y = x - 7                    [make x the subject]

x = y + 7                   [this is the inverse]

f⁻¹(x) = x + 7

(b)

(f × f⁻¹)(x) = x              [go right to left in such function]

f(x + 7) = x

(x - 7) + 7 = x

x = x

Given: g(x) = 12x

(a)

y = 12x                    [make x the subject]

x = y/12                   [this is the inverse]

g⁻¹(x) = x/12

(b)

(g × g⁻¹)(x) = x              [go right to left in such function]

g(x/12) = x

12x/12 = x                    [simplify]

x = x

Step-by-step explanation:

because VW || YZ, the 2 triangles are similar.

this is given by the rules of equal angles of intersecting lines with parallel lines. Z to V and Y to W would be such intersecting lines.

and therefore, the angle at W is the angle at Y, the angle at V is the angle at Z. and therefore both angles at A are equal.

so, for similar triangles the scaling factor between corresponding pairs of sides is the same for all sides.

e.g. the same scaling factor that converts 7.2 to 12, converts then also x to x+4.

7.2 × f = 12

f = 12/7.2 = 12/ 72/10 = 120/72 = 10/6 = 5/3

x × 5/3 = x + 4

5x = 3x + 12

2x = 12

x = 6

A to Y = x = 6

W to A = x + 4 = 6 + 4 = 10

Check the picture below.

so the height of the pole is "p", and the angle of depression to the foot of the pole is really "44 + a".

so let's use the 44° angle first

[tex]\tan(44^o )=\cfrac{\stackrel{opposite}{30-p}}{\underset{adjacent}{25}}\implies 25\tan(44^o)=30-p\implies 25\tan(44^o)+p=30 \\\\\\ p=30-25\tan(44^o)\implies \boxed{p\approx 9}[/tex]

now, let's use the red triangle, namely the angle "44 + a"

[tex]\tan(44+a)=\cfrac{\stackrel{opposite}{30}}{\underset{adjacent}{25}}\implies \tan(44+a)=\cfrac{6}{5} \\\\\\ 44+a=\tan^{-1}\left( \cfrac{6}{5} \right) \implies 44+a\approx 50^o[/tex]

Using the given information, the value of [tex]a_{4}[/tex] is 7401

From the question, we are to determine the value of [tex]a_{4}[/tex]

From the given information,

[tex]a_{n} = (a_{n-1})^{2} +5[/tex]

Then we can write that

[tex]a_{4} = (a_{3})^{2}+5[/tex]

[tex]a_{3} = (a_{2})^{2}+5[/tex]

[tex]a_{2} = (a_{1})^{2}+5[/tex]

Also, from the given information

[tex]a_{1} = 2[/tex]

Then,

[tex]a_{2} = (a_{1})^{2}+5[/tex] becomes

[tex]a_{2} = (2)^{2}+5[/tex]

[tex]a_{2} = 4+5[/tex]

[tex]a_{2} = 9[/tex]

Also,

[tex]a_{3} = (a_{2})^{2}+5[/tex] becomes

[tex]a_{3} = (9)^{2}+5[/tex]

[tex]a_{3} = 81+5[/tex]

[tex]a_{3} = 86[/tex]

Then,

[tex]a_{4} = (a_{3})^{2}+5[/tex] becomes

[tex]a_{4} = (86)^{2}+5[/tex]

[tex]a_{4} = 7396 +5[/tex]

[tex]a_{4} = 7401[/tex]

Hence, the value of [tex]a_{4}[/tex] is 7401

Answer:

Θ = 46°

Step-by-step explanation:

the angle between a tangent and a radius at the point of contact is 90° , so

∠ ABO = 90°

since OB = OD ( radii of circle ) then Δ BOD is isosceles and

∠ OBD = ∠ ODB = 22°

the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

∠ AOB is an exterior angle of the triangle , then

∠ AOB = 22° + 22° = 44°

the sum of the 3 angles in Δ AOB = 180° , then

Θ + 44° + 90° = 180°

Θ + 134° = 180° ( subtract 134° from both sides )

Θ = 46°

The length of the rectangular field is 120 ft if the width of a rectangular field is 20 feet less than its length and the area of the field is 12,000 ft².

It is defined as the area occupied by the rectangle in two-dimensional planner geometry.

The area of a rectangle can be calculated using the following formula:

Rectangle area = length x width

Let's suppose the length of the rectangular field is l and the width is w.

w = l - 20

The area of the rectangular field

lw = 12000

l(l - 20) = 12000

l² - 20l - 12000 = 0

After solving the quadratic equation, we get:

l =   120 or l = -100(length cannot be negative)

Thus, the length of the rectangular field is 120 ft if the width of a rectangular field is 20 feet less than its length and the area of the field is 12,000 ft².

The speed that Morris is travelling is 0.3 ft/s

Speed is the ratio of distance covered with respect to time.

Given the following parameters

Speed of Annesha = 50mi/hr

Speed of Moris = 3ft/s less than Aneesha

Convert 50mi/hr to ft/hr

50mi/hr = 73.3ft/s

Speed of Morris = 73.3 - 3

Speed of Morris =70.3 ft/s

A lava rock falling for five seconds will reach a height of 122.5 meters.

The missing function is y = 1/2 gt².

A function is a remark, tenet, or regulation that establishes a relationship between the two parameters.

The height of lava fountains spewed from volcanoes cannot be measured directly.

Instead, their height in meters can be found using the equation is given as

y = 1/2 gt²

where y represents the height, g is 9.8, and t represents the falling time of the lava rocks.

Then the equation will be

y = 1/2 × 9.8 × t²

The probability of picking 2 white balls and 1 black ball is 0.154

The given parameters are:

When each ball is selected, the total number of ball decreases by 1 and the type of ball also decreases.

So, the probability is represented as:

P(2 white and 1 black) = White/n * White - 1/n - 1 * Black//n - 2

Substitute known values

P(2 white and 1 black) = 12/20 * 11/19 * 8//18

The cube root of 60 is 3.87 approximately.

Step by step solution:

We can calculate the cube root by Halley's method:

The  formula is [tex]\sqrt[3]{a} = x ((x^{3} + 2a)/(2x^{3} + a))[/tex]

where,

a = number whose cube root is being calculated

x = integer guess of its cube root.

Here a = 60,

Suppose x as 3

[∵ 3³ = 27 and 27 is the nearest perfect cube that is less than 60]

⇒ x = 3

Therefore,

∛60 = 3 (3³ + 2 × 60)/(2 × 3³ + 60)) = 3.87

⇒ ∛60 ≈ 3.87

Therefore, the cube root of 60 is 3.87 approximately.

Here ,  ∛60 is irrational because it cannot be expressed in the form of p/q where q ≠ 0.

Therefore, the value of the cube root of 60 is an irrational number.

The minimum number of integers that must be picked to be sure that at least four of them have the same remainder when divided by 7 is 8.

It should be noted that that when you divide a number by 7, there are 7 possible remainders which are 0, 1, 2, 3, 4, 5, 6, and 7.

Therefore, when we select a number and divide by 7, there is a possibility that the number will be 0 less than or equal to the remainder which is less than or equal to 7.

In this case, we'll pick 8 integers to be sure that at least 4 will have same remainder.
