Answer:
To convert base A log to base B log, use the formula:
logAx = (logBx)/(logBA)
So, to convert log134 to natural logs (base e).
log134 = (loge4)/(loge13) = ln4/ln13

Solve the simultaneous equation 3x+2y=4 4x+5y=10
Answer:
2x=4-2y
x=(4-2y)/3
4x+5y=10
4[(4-2y)/3]+5y=10
(16-8y)/3+5y=10
(16-8y+15y)=10*3
7y=30-16=14
y=2
Step-by-step explanation:
The solution to the simultaneous equations 3x + 2y = 4 and 4x + 5y = 10 is x = 0 and y = 2.
To solve the simultaneous equations:
Equation 1: 3x + 2y = 4
Equation 2: 4x + 5y = 10
We can solve this system of equations using the method of substitution or elimination.
Step 1: Multiply Equation 1 by 4 and Equation 2 by 3 to make the coefficients of x in both equations the same:
Equation 1 (multiplied by 4): 12x + 8y = 16
Equation 2 (multiplied by 3): 12x + 15y = 30
Step 2: Subtract Equation 1 from Equation 2 to eliminate x:
(12x + 15y) - (12x + 8y) = 30 - 16
12x - 12x + 15y - 8y = 14
7y = 14
y = 14 / 7
y = 2
Step 3: Substitute the value of y into either equation to solve for x. Let's substitute it into Equation 1:
3x + 2(2) = 4
3x + 4 = 4
3x = 4 - 4
3x = 0
x = 0 / 3
x = 0
Therefore, the solution to the simultaneous equations 3x + 2y = 4 and 4x + 5y = 10 is x = 0 and y = 2.

Help? which one should I choose
Answer:
true
Step-by-step explanation:
For 3 sides to be able to form a triangle, we need to check that the 2 shorter sides can "touch" when "stemming" out of the long side.
The long side has length 7cm, so the sum of 2 shorter sides must be bigger than 7cm for them to "touch". Note: if the sum was 7cm, the only way they would touch is if they were laid along the long side, so it would not be a triangle - it would be a segment.
Fortunately, 3cm + 5cm > 7cm, so we can form a triangle.

An initial population of 490 quail increases at an annual rate of 6%. Write an exponential
function to model the quail population. What will the approximate population be after 5 years?
Answer:
656
Step-by-step explanation:
Given data
Initila population= 490
Rate = 6%
TIme= 5 years
Let us apply the compounding expression
A=P(1+r)^t
substitute
A= 490(1+0.06)^5
A=490(1.06)^5
A=490*1.338
A= 655.62
Hence the approximate Quail population will be 656

2.42*3.20 step by step
Answer:
7.744
Step-by-step explanation:
3.20=3.2
you can multiply just 242 and 32 then pop in the decimal point later
242*32=242*30 + 242*2
242*3*10=726*10=7260
242*2=484
7260+484=7744
2*3 (rounded version of numbers) is 6
so the answer after putting decimal point should be around 6
77.44 is way too hight
7.744 is decently close to 6
so the answer is 7.744
A corner store sells two kinds of baked goods: cakes and pies. A cake costs $15 and a pie costs $13. In one
day, the store sold 9 baked goods for a total of $121. How many cakes did they sell?
a. 8 cakes
c. 7 cakes
b. 2 cakes
d. 4 cakes
Answer:
a. 8
Step-by-step explanation: Out of 12 baked goods sold , let the number of cakes sold, be x in number and pies sold were 12 − x in number. Total sell was $ 144 , 1 cake costs $ 14 and 1 pie costs, $ 8 ∴ 14 ⋅ x + ( 12 − x ) ⋅ 8 = 144 or 14 x − 8 x = 144 − 96 or 6 x = 48 ∴ x = 8

In 1995, there were 85 rabbits in Central Park. The population increased by 12% each year. How many rabbits
populated Central Park 21 years later?
Answer:
918
Step-by-step explanation:
Given data
Initila population= 85
Rate = 12%
TIme= 21 years
Let us apply the compounding expression
A=P(1+r)^t
substitute
A= 85(1+0.12)^21
A=85(1.12)^21
A=85*10.80
A= 918
Hence the approximate Rabbit population will be 918

Which expression describes the nth term of the arithmetic sequence 5, 9, 13, 17, ...?
Answer:
4n + 1
Step-by-step explanation:
The first term is 5.
Each new term is 4 plus the previous term.
Term 1 = 5
Term 2 = 5 + 4
Term 3 = 5 + 4 + 4
Term 4 = 5 + 4 + 4 + 4
Notice that for each new term, you add one 4 less than the number of the term.
In term 1, you have 5 and no 4 added.
In term 2, you add one 4 to the 5.
In term 3, you add two 4's to the 5.
In term n, you add (n - 1) 4's to the 5.
Term n = 5 + (n - 1)4
Term n = 5 + 4n - 4
Term n = 4n + 1
Answer: 4n + 1

how can you tell if a linear equation is proportional?
Answer:
If the line goes through the origin, (0,0), that means the linear equation is proportional, if it doesn't go through the origin, the equation isn't proportional.
You can also tell if a linear equation is proportional if the equation has an constant after the x (for example y=2x+6)
How much interest will be earned in a bank account with £3850 that pays 1.3% interest each year how much will there be after 6 years
Answer:
Results are below
Step-by-step explanation:
Giving the following information:
Initial investment (PV)= £3,850
Number of periods (n)= 6 years
Interst rate (i)= 1.3% = 0.013
First, we will calculate the future value (FV), by using the following formula:
FV= PV*(1+i)^n
FV= 3,850*(1.013^6)
FV= £4,160.23
Now, by difference, the interest earned:
Interest earned= 4,160.23 - 3,850= £310.23
