Answer: -3486784401
Step-by-step explanation:
This is a geometric progression and the formula to use to find the nth term will be: = ar^(n-1)
where,
a = 3
r = -9/3 = -3
n = 20
Therefore, ar^(n-1)
= 3 × -3^19
= 3 × -1162261467
= -3486784401

for the first one it is the second option because of one property of logarithms:
log(a)-log(b)=log[tex]\frac{a}{b}[/tex]
for the second one using the same property we can say that we third option is correct and not the second one but we use one more property of the logarithm
loga(b)^x=xloga(b) the power of the logarithm becomes a fator and [tex]\sqrt[3]{x}[/tex] is equal to [tex]x^{\frac{1}{3}}[/tex]
2. The perimeter of rectangle is 48cm. If the
files are in the ratio 3 : 5, find the length
of the sides
lets the length be 3x
width be 5x
perimeter = 48
so
3x +5x=48
8x = 48
x =48/8
x= 6
so.
3x = 3×6 = 18
5x = 5×6= 30
hope it will be helpful
can someone pls help me with this? i’d really appreciate it :)
Answer:
y = 2x - 12 or A
Step-by-step explanation:
6x - 3y = 36 Subtract 6x from both sides.
-3y = 36 - 6x Divide by - 3
-3y/-3 = 36/-3 - 6x/-3
y = -12 + 2x
The answer is A
Find the exponential equation for the given information. Pls help
Answer:
y = 12 [tex](2.9)^{x}[/tex]
Step-by-step explanation:
The standard form of the exponential function is
y = a [tex](b)^{x}[/tex]
Find a and b by substituting ordered pairs from the table into the equation
Using (0, 12 ), then
12 = a[tex]b^{0}[/tex] ( [tex]b^{0}[/tex] = 1 ), so
a = 12, then
y = 12 [tex]b^{x}[/tex]
Using (1, 34.8 ) , then
34.8 = 12 [tex]b^{1}[/tex] ( divide both sides by 12 )
b = 2.9
Thus exponential function is
y = 12 [tex](2.9)^{x}[/tex]

Four banks have provided proposals for a savings account. Which scenario provides exponential growth that will best benefit the account holder?
A.The deposit increases by 3%, percent of its current value, compounded annually.
B.The deposit increases by 3%, percent of its current value, compounded monthly.
C. The deposit increases by 5%, percent of its initial value each year.
D. The deposit increases by 0.40% point, percent of its initial value each month.
Answer:
B. The deposit increases by 3% of its current value, compounded monthly.
Step-by-step explanation:
When compounded monthly that means the account is getting more money monthly rather than annually, or each year, so this answer choice would give the best benefit to the account holder. I did this problem on Khan Academy myself and this was the correct answer.

Find the diameter of a circle if its area is
a. 100cm2
Ibucm2
c. 400mcm2
d. - ncm2
4
Answer:
[tex]Diameter = 11.28[/tex]cm --- (a)
[tex]Diameter =22.58[/tex] cm --- (c)
Step-by-step explanation:
Only (a) & (c) are clear enough to be solved. Others are not properly presented.
Use the following explanations of (a) & (c) to answer others.
[tex]a.\ Area = 100cm^2[/tex]
Area is calculated as:
[tex]Area = \pi r^2[/tex]
Substitute 100 for Area
[tex]100 = \pi r^2[/tex]
Take π as 3.14. So, the expression become
[tex]100 = 3.14 r^2[/tex]
Divide both sides by 3.14
[tex]\frac{100}{3.14} = \frac{3.14 r^2}{3.14}[/tex]
[tex]\frac{100}{3.14} = r^2[/tex]
[tex]r^2 = \frac{100}{3.14}[/tex]
[tex]r^2 = 31.847133758[/tex]
Solve for r
[tex]r = \sqrt{31.847133758[/tex]
[tex]r = 5.64[/tex]
But diameter = 2 * radius
So:
[tex]Diameter = 2 * 5.64[/tex]
[tex]Diameter = 11.28[/tex]
[tex]a.\ Area = 400cm^2[/tex]
Area is calculated as:
[tex]Area = \pi r^2[/tex]
Substitute 400 for Area
[tex]400 = \pi r^2[/tex]
[tex]400 = 3.14 r^2[/tex]
Divide both sides by 3.14
[tex]\frac{400}{3.14} = \frac{3.14 r^2}{3.14}[/tex]
[tex]\frac{400}{3.14} = r^2[/tex]
[tex]r^2 = \frac{100}{3.14}[/tex]
[tex]r^2 = 127.388535032[/tex]
Solve for r
[tex]r = \sqrt{127.388535032[/tex]
[tex]r = 11.29[/tex]
But diameter = 2 * radius
So:
[tex]Diameter = 2 * 11.29[/tex]
[tex]Diameter =22,58[/tex]

Enter the range of values for x
3 < x < ?
Answer:
3 < x < 7
Step-by-step explanation:
From the diagram; |AB| = |AC|
The length AB is calculated as;
[tex]Sin\ 52^o = \frac{|BD|}{|AB|} \\\\|AB| = \frac{|BD|}{Sin\ 52^o} \\\\|AB| = \frac{12}{Sin\ 52^o} \\\\|AB| =15.228 \ m[/tex]
The length CD is calculated as;
[tex]Sin \ 31^o = \frac{|CD|}{|AC|} \\\\|CD| = |AC| \ \times \ Sin \ 31^o \\\\|CD| = 15.228 \ \times \ 0.515\\\\|CD| = 7.84[/tex]
|CD| = 2x - 6
2x - 6 = 7.84
2x = 7.84 + 6
2x = 13.84
x = 13.84 / 2
x = 6.92
x ≅ 7
Thus, 3 < x < 7

Answer:
The tree would be 27.6
Step by Step:
I took the height of the mailbox (6 ft) and its shadow (5.4) and subtracted that and got 0.6. Then I took 0.6 and added it to the shadow of the tree (27 ft) and got the answer 27.6.
Substitute it please!!
y=1-i
x=-3/2-i/2
thats what it should be
Simplify the expression
\[\frac{1}{\sqrt{2}} +\frac{3}{\sqrt{8}} + \frac{6}{\sqrt{32}}.\]
8 = 2³ and 32 = 2⁵, so
√(8) = √(2²•2) = 2√(2)
√(32) = √(2⁴•2) = 2²√(2) = 4√(2)
Then
1/√(2) + 3/√(8) + 6/√(32)
= 1/√(2) + 3/(2√(2)) + 6/(4√(2))
= 4/(4√(2)) + 6/(4√(2)) + 6/(4√(2))
= 16/(4√(2))
= 4/√(2)
Optional step: Rationalize the denominator by multiply this by √(2)/√(2) to get
4/√(2) • √(2)/√(2) = (4√(2))/2 = 2√(2)
which you can also write as √(8).

Answer:
the answers are bolded below!
Step-by-step explanation:
1. y-y1=m(x-x1)
line one- 14-4/6-1 = 10/5 = 2
so.... y-1=2(x-4)
simplified y=2x-7
line two- -2-23/1-6 = -25/5 = -5
so..... y-6=-5(x-23)
simplified y=-5x+121
b- they will intersect 1 time at (18.2,29.5)
2. No, it the system has infinitely many solutions, then the lines would be on top of each other. But since there are only two solutions, then your answer would not be infinitely many solutions.
3. y=-2x+1. This would not intersect with y=-2x+3 because they are parallel. the slopes are the same so they will each travel at the same rate but they have different y intercepts.
4. y=-2x+7 ------> x=-1/2y-7/2
y=-3(-1/2y+7/2)+8 -----> y=5
y=-2x+7 ---> 5=-2x+7 ----> x=1
one solution at (1,5) because f graphed, the lines would only intersect once.
b- x=5
3x-y=5 ---> 3(5)-y=5 ---> y=10
one solution at (5,10) because f graphed, the lines would only intersect once.
c- no solutions because if it were to be graphed, the lines would not intersect at all.
d- no solutions because if it were to be graphed, the lines would not intersect at all.
e- no solutions because if it were to be graphed, the lines would not intersect at all.

A culture of bacteria triples by the end of each hour. If there were initially 40 bacteria in a culture, how many bacteria should there be after 3 hours?
Answer:
There would be 1080 bacteria in the culture.
Step-by-step explanation:
Initial number of bacteria = 40
Given that
culture of bacteria triples by the end of each hour
Number of bacteria after 1 hour = 40*3 (multiplying initial number of bacteria by 3)
Number of bacteria after 1 hour = 120
number of bacteria after 2 hours = 3*Number of bacteria after 1 hour = 3*120
number of bacteria after 2 hours =360
number of bacteria after 3 hours = 3*Number of bacteria after 2 hour = 3*360 = 1080
Thus,
there would be 1080 bacteria in the culture.
Answer:
1080 bacteria
