Based on the relationship between Mary's age and that of John, the representation of Mary's age is (X + 5).
How old is Mary?Your question seems incomplete or not worded well so I'll give a more general response.
Mary is said to be older than John by 5 years. This means that however old John gets, Mary will always be older by 5 years.
If John is X years therefore, Mary's age will simply be:
= John's age + Age difference
= X + 5
For instance, if John is 20 years then Mary would be:
= 20 + 5
= 25 years

Answer:
[tex]y=\frac{5}{2} \:x[/tex]
Step-by-step explanation:
A line with the highest absolute value of slope has the steepest graph
from the option, the highest is 5/2 so, y = 5/2 x is your answer.

Answer:
Y=5/2x
Step-by-step explanation:
The steepest graph is the one with the largest slope (m) this is because slope is rise over run so the larger the slope the steeper the graph. Hope this helps.

You deposit $3000 in an account earning 4% interest compounded continuously. How much will you have in
the account in 5 years?
Answer: $3,664.21
Formula: [tex]A=Pe^{rt}[/tex]
P = principle/original amount = $3000r = rate of interest = 4% = 0.04t = time period (in years) = 5A = the new amounte = Euler's number ≈ 2.718...Substitute in the values:
[tex]A=(3000)e^{(0.04)(5)} =(3000)e^{0.2} =(3000)(1.2214)=3664.208[/tex]
Approximately $3,664.21
I think this is how you solve it o_O
Approximately there will be $3,664 in your account in 5 years.
What is compound interest?
The interest on a loan or deposit that is calculated using both the initial principal and the accrued interest from prior periods is known as compound interest.
Simple math may be used to demonstrate this: If you have $100 and it generates 5% interest annually, you will have $105 at the end of the first year. You will wind up with $110.25 at the conclusion of the second year.
Solution:
Since interest is compounded continuously, we need to find the future value.
A = Pe^rt, where:
P is the initial deposit
r is the rate of interest
t is the time period of deposit
A is the future value
Given,
P = $3000
r = 4%
t = 5 yrs
Therefore, future value(A) = 3000 × e^(0.03)×(5)
= 3664
Hence you will have $3664 in your account approximately.

Lena and Ras drive to work.
Lena drives 24 miles in 1.5 hours.
Ras drives 36 km in 1 hour 15 min.
Work out the difference between their average speeds in km/h.
1 mile = 1.6 km
km/h
Answer:
3.2 km/h
Step-by-step explanation:
1. Approach
The average speed is the rate at which one travels. It can be found by diving the total distance traveled over the total time it took to cover that distance. In essence, the following formula can be used to find the average speed:
[tex]\frac{total\ distance}{total\ time}=average\ speed[/tex]
In this situation, one is asked to find the difference between two people's average speed. One is given the following information:
Lena: 24 miles 1.5 hours
Ras: 36km 1 hour 15 minutes
First, convert all of the numbers into the correct units (km) and (hours). Then find the average speed for each person. Finally, subtract the smaller speed from the larger speed to find the difference in the average speeds.
1. Find Lena's average speed
The problem asks one to find the average speed in the units (km/h). However, the distance Lena covered is given in (miles). Therefore, one has to multiply it by the conversion factor (1.6) in order to convert it from (miles) to (km).
24miles * 1.6 = 38.4
Now find the average speed by using the formula:
[tex]\frac{total\ distance}{total\ time}=average\ speed[/tex]
Substitute,
[tex]\frac{38.4}{1.5}\\\\=25.6[/tex]
2. Find Ras's average speed
Use a similar approach to work out Ras's average speed, as was used to find Lena's average speed. Since Ras's time spent is given in both hours and minutes, one must convert it to just minutes. There are (60) minutes in an hour, thus, one can rewrite the number as the following:
[tex]1\ hour \ \ 15\ minutes= 1 \frac{15}{60}\ hours = \frac{75}{60}\ hours[/tex]
Now find the average speed:
[tex]\frac{total\ distance}{total\ time}=average\ speed[/tex]
Substitute,
[tex]\frac{36}{\frac{75}{60}}\\\\=28.8[/tex]
3. Find the difference between the speeds
Since Ras's speed is greater, subtract Lena's speed from Ras's speed.
Ras - Lena
= 28.8 - 25.6
= 3.2

k = 5 m = 3 (d) Work out the value of 2k + 4m
Answer:
2k = 10m+4m=3
2k =14m=8.4
The solution of the given equation is 2k + 4m = 32
What does it mean to solve an equation?An equation represents equality of two or more mathematical expression.
A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.
Solutions to an equation are those values of the variables involved in that equation for which the equation is true.
We are given the equation as;
2k + 4m
When k = 5
m = 3
Solving ;
2k = 2 (5) = 10
4m = 4(3) = 12
Then 2k + 4m = 10 + 12 = 32

Find the known measures. Round lengths to the nearest hundredth and angle measures to the nearest degree.
Answer:
KM = 10.68
K = 55 degrees
M = 35 degrees
Step-by-step explanation:
Firstly, we can use Pythagoras’ theorem to calculate the length of the hypotenuse which is KM
Mathematically, this is the sum of the squares of the two other sides KL and LM according to Pythagoras’ theorem
Thus, we have it that;
KM^2 = KL^2 + LM^2
KM^2 = 6.2^2 + 8.7^2
KM^2 = 114.13
KM = √(114.13)
KM = 10.68
We have two angles to calculate
Let us start with the angle at vertex K
The opposite side to is is the length LM which is 8.7
The adjacent side to it is the length 6.2
Mathematically, the relationship between the two can be calculated using the Tan ; as the Tan of an angle is the ratio of the length of the opposite to that of the adjacent
thus;
Tan K = 8.7/6.2
K = arc Tan (8.7/6.2)
K = 54.5 which is 55 degrees
since we have a right angle , we only have to subtract he measure of angle K from 90 to get the measure of M
M = 90-55 = 35 degrees

Answer:
D.
Step-by-step explanation:
The subtraction property involves subtracting the same number that is subtracted from one side of the equal sign and also subtracting same from the other side of the equal sign
For example: y + 3 = 2

Determine whether the series is convergent or divergent by expressing sn as a telescoping sum (as in this example). [infinity] 6 n(n + 3) n = 1
a) convergent
b) divergent
If it is convergent, find its sum. (If the quantity diverges, enter DIVERGES.)
I assume the series is supposed to be
[tex]\displaystyle\sum_{n=1}^\infty \frac6{n(n+3)}[/tex]
The summand can be expanded into partial fractions:
[tex]\dfrac6{n(n+3)}=\dfrac an+\dfrac b{n+3}[/tex]
[tex]\implies 6=a(n+3)+bn=(a+b)n+3a[/tex]
[tex]\implies\begin{cases}a+b=0\\3a=6\end{cases}\implies a=2,b=-2[/tex]
Then the sum is equivalent to
[tex]\displaystyle2\sum_{n=1}^\infty\left(\frac1n-\frac1{n+3}\right)[/tex]
Consider the N-th partial sum of the series:
2[(1 - 1/4) + (1/2 - 1/5) + (1/3 - 1/6) + (1/4 - 1/7) + (1/5 - 1/8) + …
+ (1/(N - 3) - 1/N) + (1/(N - 2) - 1/(N + 1)) + (1/(N - 1) - 1/(N + 2)) + (1/N - 1/(N + 3))]
Each of the negative terms (in bold) will have a positive counterpart (underlined) that cancel, so the N-th partial sum would be
[tex]\displaystyle\sum_{n=1}^N\frac6{n(n+3)} = 2\left(1+\frac12+\frac13-\frac1{N+1}-\frac1{N+2}-\frac1{N+3}\right)[/tex]
As N approaches infinity, the last three terms in the sum converge to 0, so the original sum converges to
[tex]\displaystyle\sum_{n=1}^\infty \frac6{n(n+3)} = 2\left(1+\frac12+\frac13\right) = \boxed{\frac{11}3}[/tex]

It means the given function is defined if the value of (x-3) is greater than or equal to 0.
[tex]x-3\geq 0[/tex]
Adding 3 on both sides, we get
[tex]x-3+3\geq 0+3[/tex]
[tex]x\geq 3[/tex]
The inequality [tex]x-3\geq 0[/tex] is used to find the domain of the given function and the domain of the given function is [tex]x\geq 3[/tex].
