The required linear function to model the amount of money in Iri's account at any time t using the simple interest formula is 185 + 5.55t.
What is interest?An expense associated with borrowing money or other assets is interest.
The principal is the amount borrowed, and the interest is calculated as a percentage of the principal for a specific period of time.
If someone borrowed $1,000 at 2% interest and accumulated $100 in interest, the interest for that year would be $22.
It's because interest is paid on a total of $1100, which includes the principal ($1000) and accrued interest ($100). 2% of $1100 is $22.
So, in this situation, the checking account offers simple interest at a rate of 3% annually. Her account has $185 in it.
The total balance of the account will always be:
= 185 + (PRT/100)
P = principal
R = rate
T = time
Then,
= 185 + [(185 × 3 × t)/100]
= 185 + 5.55t
185 + 5.55t is the function.
Therefore, the required linear function to model the amount of money in Iri's account at any time t using the interest formula is 185 + 5.55t.

Graphing a functionFrom the question, we are to graph the given function.
From the given information,
The given function is
g(x) = -5^x + 5
To graph the function, we will determine some of the points on the line
When x = -2
g(2) = -5^(-2) + 5
g(2) = -1/25 + 5
g(2) = 4 24/25 = 4.96
When x = -1
g(1) = -5^(-1) + 5
g(1) = -1/5 + 5
g(1) = 4 4/5 = 4.8
When x = 0
g(0) = -5^(0) + 5
g(0) = -1 + 5
g(0) = 4
When x = 1
g(1) = -5^(1) + 5
g(1) = -5 + 5
g(1) = 0
When x = 2
g(2) = -5^(2) + 5
g(2) = -25 + 5
g(2) = -20

The required linear equation that defines the dependent variable, p, in terms of the independent variable, t is p = 3t + 4.
Explain linear equation?A linear equation is a mathematical condition of the structure y=mx+b. including just a steady and a first-request (straight) term, where m is the slant and b is the y-catch. Sometimes, the above is known as a "straight condition of two factors," where y and x are the factors.
According to question:Let linear equation be p = at + b
Where a and b are constant.
On putting the values from the table,
4 = 0×a + b
b = 4
and,
7 = 1×a + b ⇒ a + b = 7
a + 4 = 7

The equation g(x) = |-x-3| + 2 would reflect the function over the y-axis.
The required value of f(3) is 10.
What is a reflection across the y-axis?Reflection across the y-axis is defined as reflecting a point across they = x, the x-coordinate, and y-coordinate places, the line y = -x is the coordinates (-x, y).
So reflected across the y-axis: f(x) → f(-x),
⇒ (x,y) → (-x , y)
As per the given question,

liters/minute, where t is in minutes since the pump is started. if the holding tank contains 1000 liters of water when the pump is started, approximately how much water does it hold two hours later?
Approximately, water does it hold two hours later is = 248.72 liters
Given that,
The holding tank contains 1000 liters of water
Water does it hold two hours later,
Then,
1) Integrate the function, from t =0 to t = 120 minutes to obtain the number of liters pumped out in the entire interval, and
2) Substract the result from the initial content of the tank (1000 liters).
So
We can write,
Let us assume,
Integral of (6 - 6 [tex]e^{-0.13t}[/tex] ) dt ]from t =0 to t = 120 min
= 6t + 6 [tex]e^{-0.13t}[/tex] / 0.13
= 6t + 46.1538 6 [tex]e^{-0.13t}[/tex] ] from t =0 to t = 120 min
= 6*120 + 46.1538 e^(-0.13*120) - 0 - 46.1538
= 720 + 46.1538 (1.678) - 46.1538
= 720 + 77.44 - 46.1538 liters
= 751.28 liters
2) If the holding tank contains 1000 liters of water,
1000 liters - 751.28 liters = 248.72 liters
Therefore,
Approximately, water does it hold two hours later is = 248.72 liters

Decide whether enough information is given to prove that the triangles are congruent using the HL Congruence Theorem. Explain.
Answer:
No
Step-by-step explanation:
You want to know if there is enough information to claim ∆PQT ≅ ∆SRT by the HL theorem.
HL theoremThe HL theorem tells you right triangles are congruent if they have one leg (L) and the hypotenuse (H) congruent.
Here, the triangles are not indicated as being right triangles, so the HL theorem cannot be applied.
__
Additional comment
There is not enough information here to permit the triangles to be declared congruent.
For congruence by any theorem, we'd need to know that angle T is the largest angle in each triangle, a condition not supported by the evidence.
Though rarely (if ever) seen in congruence discussions, a claim of SSA congruence can only be supported if the angle (A) is opposite the longest side. When the angle is 90°, this is called the HL congruence theorem. When the angle is known to be obtuse, it will always be opposite the longest side.
When the given angle is opposite the shortest of the two given sides, there are two possible triangles that can be constructed. Hence congruence cannot be guaranteed between two triangles with the same SSA dimensions.

Write the equation of 5x-y=15 after it is reflected in the y-axis and then translated (3 -1)
Answer: y=-5x-1. I need someone to tell me what translating equations is and how to get there.
The equation after the transformation is y = -5x - 1
How to determine the equation after the transformation?From the question, we have the following parameters that can be used in our computation:
Equation: 5x - y = 15
Make y the subject
So, we have
y = 5x + 15
The rule of reflection across the y-axis is
(x, y) = (-x, y)
So, we have the following equation
y = -5x + 15
The rule of translation by (3 -1) is
(x, y) = (x + 3, y - 1)
So, we have the following equation
y = -5(x + 3) + 15 - 1
Expand
y = -5x - 15 + 15 - 1
So, we have
y = -5x - 1
Hence, the equation is y = -5x - 1
