a triangle undergoes a dilation with a scale factor of 9/5. the resulting triangle is _[blank]_ the original triangle.
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.

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).To learn more about probability, refer:

Solve for the following
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?
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
the rocket's flight time is 8 seconds.

A computer store buys a computer system at a cost of $436.80. The selling price was first at 728, but then the store advertised a 20% markdown on the system. Answer part b.
A= 582.40
Members of the store's loyalty club get an additional 20% off their computer purchases. How much do club members pay for the computer with their discount?
The price for club members is $______
please help
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:
582.40 - (20% × $582.40)
= $582.40 - $116.48

Find the distance of a line with endpoints (1, 2) and (7, 4). Round to the nearest tenth.
Distance Formula:
d=√√(x₂-x₁)² + (y₁ - y₁)²
The distance between the two points is 2√10
Distance between two points:
The formula for the distance between two points (x₁, y₁) and (x₂, y₂) is given by Distance = √ [(x₂-x₁)² + (y₁ - y₁)²]
This formula can be used to find the length of a line whose endpoints are (x₁, y₁) and (x₂, y₂)
Here we have
The endpoints of the line are (1, 2) and (7, 4)
As we know d =√ [(x₂-x₁)² + (y₁ - y₁)²]
Take (x₁, y₁) = (1, 2) and (x₂, y₂) = (7, 4)
By the given formula,
Distance of line = √ [(7 - 1)² + (4 - 2)²]
= √[(6)² + (2)²]
= √(36 + 4)
= √40
= 2√10

Mr. Ramli is a small entrepreneur, he wants to invest RM 2000 in a spice business. He
is confident that his investment, RM y will increase at a rate 2(x+121) which x is time
in year.
Find the number of years it takes for his investment money to be doubled from his
original investment.
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.

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

[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.
