1.3 minutes does the tortoise walk.
What is speed- distance formula?Speed, time, and distance relationships
Distance/Time x Speed This reveals how quickly or slowly an object is moving. It gives the amount of time it took to travel a certain distance divided by the distance travelled.Speed is inversely correlated with time and directly correlated with distance. Therefore, as the speed increases, the time required, because Time = Distance / Speed. Distance = Speed X Time.Each Speed, Distance and Time can be expressed in different units:
Time: seconds(s), minutes (min), hours (hr)Distance: (meters (m), kilometers (km), miles, feetSpeed: m/s, km/hrGiven:
distance= 5.2 m
speed= 4 m/ min
Now using
speed= Distance / time
4 = 5.2 / time
time= 5.2/4
time= 1.3 minutes.
Hence, 1.3 minutes does the tortoise walk.

If the same number is added to the nunerator of 12/13 and subtract from the denominator, the new fraction is equal to 3/2. What is the number?
Answer:
x = 3
Step-by-step explanation:
If the same number is added to the numerator of 12/13 and subtract from the denominator, the new fraction is equal to 3/2. What is the number?
[tex]\frac{12+x}{13-x} =\frac{3}{2}[/tex]
multiply both sides by 13-x:
[tex](13-x)\frac{12+x}{13-x} =\frac{3}{2}(13-x)\\\\12+x = \frac{3(13-x)}{2} \\\\12+x = \frac{39-3x}{2} \\[/tex]
multiply both sides by 2:
[tex]2(12+x) = (\frac{39-3x}{2})\\\\24+2x = 39-3x[/tex]
subtract 24 from both sides:
24 + 2x - 24 = 39 - 3x - 24
2x = 15 - 3x
add 3 x to both sides:
2x + 3x = 15 - 3x + 3x
5x = 15
divide both sides by 5:
5x/5 = 15/5
x = 3
check:
[tex]\frac{12+x}{13-x} =\frac{3}{2}\\\\\frac{12+3}{13-3} =\frac{3}{2}\\\\\frac{15}{10} =\frac{3}{2}\\\\\frac{3}{2} =\frac{3}{2}[/tex]

The simple interest formula is:

where A is the final amount, P is the principal, r is the annual interest rate (as a decimal) and t is time in years.
Substituting with P = 1,300, r = 0.06 and t = 3, we get:

The value of c is a true zero of the polynomial function P(x)
How to show that c is a zero of the polynomial?The polynomial function is given as
P(x) = x³ + 3x² - 16x - 48
Also, we have the value of c to be
c = -3
If truly, the variable c is a zero of the polynomial, then the following must be true
P(c) = 0
Start by substituting -3 for c in the equation P(x) = x³ + 3x² - 16x - 48
So, we have
P(-3) = (-3)³ + 3(-3)² - 16(-3) - 48
Evaluate the exponents
P(-3) = -27 + 3(9) - 16(-3) - 48
Evaluate the products
P(-3) = -27 + 27 + 48 - 48
Evaluate the sum and the difference
P(-3) = 0
Recall that
c = -3
So, we have
P(c) = 0
Hence, c is a zero of the polynomial because P(c) = 0

A sequence is given by the equation an= 1/4n where a1 = 512 and n > 1 and is a
whole number.
What are the first 4 terms of the series?
Series:
The first 4 terms of the sequence are 512 , 128 , 32 and 8 .
In mathematics, a sequence is a named collection of elements where repeats are allowed and order matters.
It has pieces, much like a set (also called elements, or terms). The number of items determines how long the series is (potentially infinite). The same elements could appear in a sequence more than once at different places in contrast to a set, where the order is crucial. Formally, a sequence can be defined as a relationship between the items at each of the positions in the sequence and natural numbers (the positions of the sequence's constituents). It is possible to think of an indexed family, which is a function from any index set, as a generalization of the concept of a sequence.The formula for the sequence is given by aₙ = 1/4 aₙ₋₁
It is given that a₁ = 512
Hence a₂ = 1/4 a₁ = 1/4 × 512 = 128
a₃ = 1/4 a₂ = 32
a₄ = 1/4 a₃ = 8
Therefore the first 4 terms of the sequence are 512 , 128 , 32 and 8 .

If you buy a car for $24,686 and it depreciates linearly at a rate of 8% per year, what will be its value after 6 months?
The value of a car after 6 months will be $23,698.56.
What is mean by Percentage?
A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
To Calculate the percent of a number , divide the number by whole number and multiply by 100.
Given that;
Cost of a car = $24,686
And, The cost of a car is depreciates linearly at a rate of 8% per year.
Now,
The depreciated cost of a car in 1 year = 8% of $24,686
= 8/100 x $24,686
= $1,974.88
So, The depreciated cost of a car in 1 year will be $1,974.88
Since, In 1 year there is 12 month.
Hence, The depreciated cost of a car in 6 month = $1,974.88 ÷ 2
= $987.44
Therefore, The value of a car after 6 month = $24,686 - $987.44
= $23,698.56
Hence, The value of a car after 6 months will be $23,698.56.

What constitutes a function?
A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output. Each function has a range, codomain, and domain.
Four main categories can be used to classify different sorts of functions. One to one function, many to one function, onto function, one to one and into function—all based on the element.

Aisha earned some money doing odd jobs last summer and put it in a savings account that earns 14% interest compounded monthly. After 7 years, there is $300.00 in the account. How much did Aisha ea doing odd jobs? Round your answer to the nearest cent.
Aisha earned some money doing odd jobs
Let P be the amount earned doing odd jobs
she saved the money for 7 years
The interest is 14%
Using the formula
A = p(1 + r/n)^nt
Let P = principal
t= time
r = rate
n = compounded period
Since, the money is compounded monthly, then n = 12
A = $300.00
r = 14%
r = 14/100 = 0.14
t = 7
n = 12
substituting the above figures in to the formula
$300 = P( 1 + 0.14/12)^12 x 7
300 = P( 1 + 0.0116)^84
300 = P (1.0116)^84
300 = P(2.635)
300 = 2.635P
Divide both sides by 2.635
300/2.635 = 2.635P/2.635
P = $113.85
Approximately $114

The y-intercepts are the values of y such that f(y) = 0, solving that we will get:
y-intercepts: -6.93, 6.93.
How to find the y-intercepts of the function?
Here we have a function that depends of y, and we want to find the y-intercepts.
The function is:
f(y) = 5*y^2 - 240
The y-intercepts are the values of y such that the function becomes zero, so we need to solve:
0 = 5*y^2 - 240
240 = 5*y^2
240/5 = y^2
48 = y^2
Now we apply the square root in both sides to get:

±6.93 = y
