Answer:
Percent increase : 20%
Step-by-step explanation:
First month: 4,264 phone calls.
Second month: 25% more phone calls than in the first month.
To know the total phone calls received during this month you must take 25% of 4,264 and then add it to the 4,264 call of the first month:
64,264*25%=1,066
Total phone calls of the second month: 1,066+ 4,264= 5,330
You can also calculate the total phone calls of the second month by multiplying 4264 times 1,25 because times 1 is the same number and times 0,25 is the percent increase in the number of calls:
4,264*1,25= 5,330
Third month: 6,396 phone calls
To know the percent increase in the number of phone calls from the second month to the third month you must use the percent change formula:
Percent change: ((value2-value1)/ value 1 )*100%
Value 2: phone calls received during the third month
Value 1: phone calls received during the second month
Percent change: ((6,396-5,330)/ 5,330 )*100%
Percent increase: 20%

Solve log (x 1) = –x2 10 by graphing. Which equations should be graphed?.
Equal expressions can be taken as equal to some third quantity (which is not used previously, and is new). The equations for given equation to graph are: and
What is logarithm ?When you raise a number with an exponent, there comes a result.
Lets say you get
[tex]a^b = c[/tex]
Then, you can write 'b' in terms of 'a' and 'c' using logarithm as follows
[tex]b = \log_a(c)[/tex]
Log with base 10 is written as [tex]\log(x)[/tex] mostly.
For the given equation, using the above definition, we get:
[tex]log(x+1) = -x^2 + 10\\\\\\(x+1) = 10^{-x^2 + 10}\\x + 1 = 10^(-x^2} \times 10^10 = y\: \: \rm (say)\\[/tex]
Then we get two equations as:
[tex]y = x + 1\\y = 10^(-x^2} \times 10^10[/tex]
Graphing those equations and then getting their common intersection point will give us the solution, as plotted below in the attached graph.

Identify the relation that is a function. city name to state name number of apples purchased to the cost of the apples days of the week to the months of the year last name to phone number
Answer:
number of apples purchased to the cost of apples
Step-by-step explanation
The only relation that is a function is number of apples purchased to the cost of the apples.
A relation is considered a function if each input (domain element) is associated with exactly one output (range element). Let's analyze the given relations:
City name to state name: This is not necessarily a function. Multiple cities can be in the same state.
Number of apples purchased to the cost of the apples: This is a function. Each number of apples purchased is associated with a single cost of apples.
Days of the week to the months of the year: This is not a function. Some days of the week might correspond to multiple months.
Last name to phone number: This is not necessarily a function. Different people with the same last name could have different phone numbers.

find two numbers if their sum is 7.2 and their difference is 2.7
Answer:
4.95 and 2.25
Step-by-step explanation:
x+y=7.2
x-y=2.7
Add equations
x+y + x-y= (2x-y+y)=2x
7.2+2.7=9.9
Therefore 2x=9.9 x=9.9/2=4.95
x=4.95
x+y=7.2
4.95+y=7.2
y=7.2-4.95=2.25
y=2.25
Answer:
4.95 and 2.25.
Step-by-step explanation: This is really long... (PLEASE TAKE NOTE THE INFO ISNT DIRECTLY WRITTEN BY ME).
Adding equations (1) and (2), we get
Therefore
x=4.95
Substituting value of x from (3) in (1), we get
y=2.25
From (3) and (4), the two numbers are 4.95 and 2.25.

Delisile spends 30% of her income on rent and 50%of the remaining on food and travelling. she pays R2200,00 per month for education and now has R3120,00 left . her monthly income is
The total monthly income of Delisile including her spendings is R 1,520,000
How to find Delisile monthly incomeGiven:
x = Total monthly incomeAmount spent on rent = 39% of x= 0.30x
Amount remaining = x - 0.30x
= 0.70x
Amount spent on food and traveling = 50% of 0.70x
= 0.50 × 0.70x
= 0.35x
Amount spent on education = R 220,000Amount left = R 312,000Total = rent + food + education + amount left
x = 0.30x + 0.35x + 220,000 + 312,000
x = 0.65x + 532,000
x - 0.65x = 532,000
