Jayden was excited to get his test back for his
parents to sign He scored a 105%. He
received the extra 5 points for showing his work.
Which decimal represents his test score?
Answer:
1.05
Step-by-step explanation:
100% is 1.0, therefore 105% will be 1.05.
Explanation:
Think of 105% as 105.0%
Now remove the percent sign to get 105.0
Lastly, move the decimal point two spots to the left to get to 1.05
Percentages that are over 100% convert to decimal values larger than 1; on the flip side, percentages that are under 100% are between 0 and 1.
More Examples:
76% = 0.76
18% = 0.18
255% = 2.55

The correct option regarding the high tide and the low tide is given as follows:
B. high tide at 6 a.m. and 6 p.m., depth of 28 ft.
low tide at 12 midnight and 12 noon, depth of 20 ft.
What is the definition of the cosine function?The cosine function is defined as follows:
g(x) = acos(bx+c)+d.
The coefficients have these following roles:
a: amplitude.b: The period is of 2π/B.c: phase shift.d: vertical shift.The amplitude for this problem is of 4, with a vertical shift of 24, hence the low and high tides are given as follows:
Low: -4 + 24 = 20 ft.High: 4 + 24 = 28 ft.The function is reflected over the x-axis, due to the multiplication by the negative number, hence the low tide is at midnight.
The period of the function is given as follows:
2π/(π/6) = 12 hours.
Thus the low tide also happens at noon, meaning that option B is correct.

The degree of polynomial is 2 and leading coefficient is 3.
What are polynomial?A polynomial is a mathematical expression made up of one or more terms. The phrases "poly" and "nominal," for example, are whence the name "polynomial" arose. The words "poly" and "nominal" both signify many. A polynomial is an algebraic expression with two or more algebraic terms, to put it simply. It has exponents, operators, coefficients, coefficients, variables, and constants.
Given polynomials 9, 3x², 8x
standard form of polynomial; The value of the largest exponent in a polynomial is known as its degree. However, it differs between a polynomial with just one variable and one with multiple variables. The degree of a polynomial for a single variable is equal to the variable's highest power in the polynomial.

Answer:
The fraction 480/840 can be reduced to its lowest terms by dividing the numerator and denominator of the fraction by their greatest (highest) common factor (divisor), gcf (hcf, gcd). This results in a reduced fraction of 4/7.

A person invested \$5,600$5,600 in an account growing at a rate allowing the money to double every 6 years. How long, to the nearest tenth of a year would it take for the value of the account to reach \$72,500$72,500?
Answer:
22.2 years
Step-by-step explanation:
Doubling formula is given as:
P(t) = Po × (2)^t/k
Where
Po = Initial amount invested = $5600
P(t) = Amount after time t = $72500
k = Time it takes to double = 6 years
t = Time in years = ??
Hence:
72500 = 5600 × (2)^t/6
Divide both sides by 5600
72500/5600 =( 5600 × (2)^t/6)5600
12.946428571 = (2)^t/6
Take the In of both sides
In 12.946428571 = In (2)^t/6
In 12.946428571 = t/6 In (2)
Divide both sides by In 2
In 12.946428571/In 2 = t/6
3.6944822628 = t/6
Cross Multiply
t = 6 × 3.6944822628
t = 22.166893577 years
Approximately
t = 22.2 years
Therefore, it would take 22.2 years

Please find attached the graph showing the translation transformation of the triangle ΔABC with vertices A(2, 1), B(-1, 2), and C(-2, -1) using the rule (x, y) → (x - 1, y - 3), to produce triangle ΔA'B'C' with vertices A'(1, -2), B'(-2, -1), and C'(-3, -4), created with MS Excel
What is a translation transformation?A translation transformation is one in which the location of the points on the original figure slides by the same amount and in the same direction to form the image.
The vertices of the triangle ΔABC are; A(2, 1), B(-1, 2), and C(-2, -1)
The specified transformation is; (x, y) → (x - 1, y - 3)
Applying the specified transformation, we get;
A(2, 1) ⇒ (x, y) → (x - 1, y - 3) ⇒ A'(2 - 1, 1 - 3) = A'(1, -2)
B(-1, 2) ⇒ (x, y) → (x - 1, y - 3) ⇒ B'(-1 - 1, 2 - 3) = B'(-2, -1)
C(-2, -1) ⇒ (x, y) → (x - 1, y - 3) ⇒ C'(-2 - 1, -1 - 3) = C'(-3, -4)
The vertices of the image ΔA'B'C' of the triangle ΔABC following the transformation, (x, y) → (x - 1, y - 3) are therefore;
A'(1, -2), B'(-2, -1), C'(-3, -4)

The limit is x---->4-
The negative show that x approaches from the left
Now
As x approaches 4 from the left ... Means This number should be less than 4 (<4) but really close to 4.
Let's pick a Number
Say 3.99
Substitute this... You have
3.99/3.99-4
3.99/-0.01
If we choose x to be 3.999
we will have
3.999/-0.001
Notice the pattern... As x approaches 4 from the left... This limit will approach NEGATIVE INFINITY
Why?
As you approach 4 from the left... 3.9,3.99,3.999... You notice that the denominator becomes negative and EXTREMELY SMALL... and when you divide by an extremely small Number..... You'll get a relatively HUGE VALUE(You can try this... Use a calc... Divide any number of choice by a very small number... say.. 0.0000001.... You'll get a huge result
In our case... The denominator is negative... So it Will Approach a very Huge Negative Number
Hence
Answer.. X WILL APPROACH NEGATIVE INFINITY.
Vertical asymptotes are the zeroes of the denominator of a function
The denom. is x-4
Equate to zero to get the asymptote
x-4=0
x=4
Hence... There will be a vertical asymptote at x=4.

2) Julie wants to purchase swim lessons for her son. There are four different stores that offer swim lessons. Based on the lowest cost per minute, which store has the BEST deal ?
Store A: $25 for a 45 minute lesson, Store B: $30 for a 1 hour lesson, Store C: $45 for a 1.5 hour lesson, and Store D: $80 for three 1 hour lessons
Store C offers the best deal
Based on the lowest cost per minute, Store C has the best deal. It charges $45 for a 1.5 hour lesson, which works out to $0.30 per minute. The other stores charge more per minute: Store A charges $0.56 per minute, Store B charges $0.50 per minute, and Store D charges $0.40 per minute for each of the three 1 hour lessons.
Store A has the highest cost that is $0.56 per minute
Next Store B comes in the 2nd place which costs around $0.50 per minute.
After that Store D charges at the rate of $0.40 per minute.

You start driving west for 5 miles, turn left, and drive south for another 8 miles. At the end of driving, what is your straight line distance from your starting point? Round to the nearest tenth of a mile.
Answer: 9.4
Step-by-step explanation: plug it into Pythagorean Theorem equation
The straight line distance from your starting point if You start driving west for 5 miles, turn left, and drive south for another 8 miles is 9.4 miles.
What is the right-angled triangle?A triangle whose one is 90 degrees is considered a right-angled triangle. Pythagoras' theorem is applied only to the right-angled triangle.
Given:
The distance to the west, W = 5 miles,
The distance to the south, S = 8 miles,
As it will make a right-angle triangle, so by using Pythagoras' theorem the hypotenuse will be the straight line distance from the starting,
Straight Distance = [tex]\sqrt{W^2 + S^2}[/tex]
Substitute the values,
Straight Distance = [tex]\sqrt{5^2 + 8^2}[/tex]
Straight Distance = 9.4 miles
Therefore, the straight line distance from your starting point if You start driving west for 5 miles, turn left, and drive south for another 8 miles is 9.4 miles.

What are the first 3 triangular numbers?
The depiction of numbers as an equilateral triangle organized in a series is known as a triangular number sequence. These numerals follow a 1, 3, 6 order.
Explain the term triangular numbers?A number that may be expressed as the sum of the initial n positive integers is referred to as a triangular number.
For instance, the fact that 6 may be expressed as 1+2+3, being sum of the initial three positive integers, indicates that it is a triangular number. If one takes the sum of the initial positive integer to be the first element, then sum of the earliest two positive integers to be the second element, then so on, triangular numbers comprise a sequence. In this scenario, n signifies the position of such a triangular number with in sequence if a number equals the sum of the initial n positive integers. Triangles can be formed from triangular numbers.Thus, the first three triangular numbers 1, 3, 6.
