The resulting triangle is 9/5 the original triangle.

How triangle dilated with scale factor?

The focuses in the direction planes are A(0, 2), B(2, 1), C(- 2, - 2). In the event that the scale factor is 2, each direction point of the first triangle is duplicated by the scale factor 2. Subsequently, the expanded triangle will be A'B'C' and the direction focuses got are A'(0, 4), B'(4, 2), C'(- 4, - 4).

According to question:

Let we have a triangle ABC,If this triangle undergoes a dilation with a scale factor of 9/5,

Then changed triangle is  A'B'C'

So, relation between them is A'B'C' = 9/5(ABC)

Thus, the resulting triangle is 9/5 multiple of triangle ABC.

Find the indicated angle using trigonometry

Answers

The measure of indicated angle in the given triangle is 71.035°.

What are trigonometric ratios?

The sides and angles of a right-angled triangle are dealt with in Trigonometry. The ratios of acute angles are called trigonometric ratios of angles. The six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec).

In the given right angled triangle, hypotenuse side is 74 units and the two legs of triangle are 70 units and 24 units.

Let the unknown angle be x.

We know that, tanθ =Perpendicular/Base

Now, tan x= 70/24

tan x= 2.91

x =71.035°

So, one of the angle in the triangle is 71.035°.

Therefore, the measure of unknown angle is 71.035° in the given triangle.

Step-by-step explanation:

A square garden is surrounded by a concrete walkway of width x. The length of the walkway is 15 feet long
a) Write an expression for the area of the garden.
The formula for the area of a square is A = s^2, where s is
a side length of the square.
A(x) = (15 + 2x)
b) Consider the information given above and discuss the maximum and minimum size of the concrete walkway. Be sure to explain your estimates.

Answers

Considering the information, the minimum and maximum size of the concrete walkway is is -900 and -450 units respectively

How to determine the minimum and maximum values?

Minimum and maximum values of the area of the square garden is the area the square garden can occupy.

The given parameters are

A=S²

S= a side of the square= A(x) = (15+2x)

Now, hence A=S²

This implies that

(15+2x)(15+2x)

Expand the brackets to get

225+60x+4x=0

Solving the equation using the quadratic formula

x=± (√b²-4ac)÷2a

This implies that  

x= -60±(√60²-4*4*225)÷2*4

Simplifying the equation we have

(-60±0)÷8

x=-30

Now if x= -3

Therefore (15+2*-30) = -45 and (15*x)

= 15*-30=-450 units

The probability that both choose Black Panther as their favourite character is 189/3875.

How is the probability calculated?

KHS students' list of their favourite Marvel comic character:

Spiderman - 45

Black widow - 17

Rocket raccoon - 5

Total = 125

The chances that two people can be drawn from a sample of 125 playing cards in 125[tex]C_{2}[/tex] ways.

What is probability?The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty. The likelihood that an event will occur increases with its probability. Probability informs us of the likelihood that an event will occur given enough trials.Probabilities can be expressed numerically by the number of desired outcomes, divided by the total number of outcomes, when dealing with experiments that are random and well-defined in a purely theoretical context (like flipping a coin).

The value of ordered pair of   (x,y) is (-2, -3)

How to solve the equation by substitution method ?

x - 5y = 13

4x - 3y = 1

Solve the equation for x

x - 5y = 13

Move '5y' to R.H.S and change it's sign

x=13+5y

Substitute the given value of X into the equation

4x - 3y = 1

4(13+5y)-3y = 1

Solve the equation for y

distribute 4 through the parentheses

52+20y -3y =1

Collect like terms

52+17y = 1

Move constant to R.H.S and change it's sign

17y = 1 - 52

Calculate

17y =  - 51

Divide both sides of the equation by 17

17y/17 = -51/17

Calculate

y = -3

Now, substitute the given value of y into the equation

x = 13 + 5y

x= =13+5x(-3)

Solve the equation for x

Multiply the numbers

= 13 - 15

Calculate the difference

= -2

The possible solution of the system is the ordered pair

( x , y )

What is Unitary Method?

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

As, Maximum miles driven=highest consumption per gallon × Maximum  

                                                                                                         gallons

where;

Maximum miles driven per person=64 mile

Maximum miles driven = 64×4

                                     =256 miles

So, highest consumption =24.56 miles per gallon

let the Maximum gallons needed be x

256=24.56 x

24.56 x=256

x ≥ 256/24.56

x ≥10.42 gallons

Hence, No, the estimate should be higher

what is the probability of having the first head at the k-th trial? what is the name of this random variable?

Answers

The probability of having the first head at the k-th trial is 1/2.

The formula for the binomial distribution of probability is shown below. It can be used to determine the likelihood of getting K heads out of N coin tosses.

[nC k]* [pk]* [qn-k]

p= probability of receiving a head and

q= probability of having a tail.

Both p and q are 1/2.

As a result, the equation is [f12n! * f! r! * (n-r)!]

If you obtain exactly r successes, you also get (n - r) failures at the same time.

qn - rpr = P(getting r successes and n - r failures) (since the n trials are independent) Using the product theorem

There is no mention of the challenges from which the results were attained. There are nCr methods for selecting successful trials among r trials. The remaining (n - r) trials should be failures once the r trials that were picked for successes have been chosen. These nCr methods are incompatible. P(obtaining exactly r successes) in each of these nCr methods equals qn - rpr.

Answers

The price that that club members pay for the computer is $465.92.

How to calculate the price?

A percentage is a value or ratio that may be stated as a fraction of 100. If we need to calculate a percentage of a number, we should divide it's entirety and then multiply it by 100. The percentage therefore refers to a component per hundred.

Since the selling price was first at 728, but then the store advertised a 20% markdown on the system and members of the store's loyalty club get an additional 20% off their computer purchases.

The cost will be calculated thus:

A rocket is fired with an initial vertical velocity of 40 m/s from a launch pad 45 m high.  Its height is given by the formula , where h is in meters and t is in seconds.  How high does the rocket go? How much time is the rocket in flight?

Answers

The maximum height which the rocket attains is 80 m and the time taken by the rocket is 8 sec.

Given,

the following formula yields the height h,

h= -5t² + 40t +45

45m is the height of the launch pad.

We take the first derivative of the function h and then set it to zero to determine the height the rocket reaches.

h' = 0

-10t + 40 =0

-10t = -40

 t = 4

Therefore, height reached by the rocket in time t = 4 is,

h= -5t² + 40t +45

  = -5(4)²  + 40(4) + 45

  =125 m

As a result, the rocket can reach:

125- 45

= 80 m

(To determine the real height the rocket travels, we have subtracted the height of the launch pad.)

The rocket takes twice as long to launch as it does to reach the peak.

t = 2*4 = 8 sec

Therefore,

the rocket goes 80 meters in height

Find the number of years it takes for his investment money to be doubled from his
original investment. ​

Answers

Mr. Ramli's investment in the small entrepreneurship will be doubled in 8 year.

Explain the term rate of change?The term "rate of change" (ROC) describes the rate which something evolves over time. Thus, it is not the amount of specific changes themselves but rather the acceleration or slowdown of changes (i.e., the rate). Rate of change is a tool used in finance to comprehend price returns and spot trend momentum.

For the stated equation-

rate of increase is given as-

dy/dx = 2(x + 121) < - rate of the change

dy = 2(x + 121)dx

Integrating;

∫dy = ∫2(x + 121)dx

y = x² + 242x + C

At x = 0, y(0) = 0 Thus,

(0)² + 242(0) + C = 2000

C = 2000

Now, y = x² + 242x + 2000

Calculate 't' to get the y(t) = 40,000 (double the amount)

4000 = x² + 242x + 2000

x² + 242x - 2000 = 0

Find the factor;

x = 8 and x = -250

As, x is time in year. So, x = 8 years.

Therefore, it takes eight years for his investment capital to double from what he initially put up.
