Answer: a₉ = 327,680
Step-by-step explanation:
This seems to be a geometric sequence.
The recursive relation for this type of sequence is:
aₙ = aₙ₋₁*r
Where r is a constant.
Then we also have:
aₙ/aₙ₋₁ = r.
then we can find the value of r if we take the quotient of different consecutive terms, for example, the quotient of the second and firs term is:
r = 20/5 = 4
And the quotient between the third and second term is:
r = 80/20 = 4
Then we can conclude that r = 4.
And also, the n-th term of this sequence can be written as:
aₙ = a₁*r^(n - 1)
such that:
a₁ = 5
r = 4
Then the n-th term of this sequence is:
aₙ = 5*(4)^(n - 1)
Then the term a₉ can be found if we just replace n by 9 in the above equation:
a₉ = 5*(4)^(9 - 1) = 5*(4)^(8) = 327,580
5. Here are the first four terms of an arithmetic sequence: 6, 10, 14, 18..
a) First the sum of first 30 terms of the sequence.
Answer:
it hard too
Step-by-step explanation:
it's hard also so
Answer: 180
an = a1 + (n - 1)d
a1 = 6 [1st term]
d = 4 [common difference]
n = 30 [30th term]
a30 = 6 + (30 - 1)*6 = 180

Jesse bought a 340-gram bag of coffee beans. He uses 18.75 grams of coffee beans each day. When there are 40 grams of coffee beans remaining in the bag, Jesse will buy another bag to
make sure
he doesn't run out of coffee.
How many days can be use the 340-gram bag of coffee beans before he buys a new bag?
Answer:
Jesse should buy a new bag in 16 days.
Step-by-step explanation:
He uses 18.75 grams a day.
We can multiply the amount of grams by the amount of days.
18.75 x 16 = 300
He stops using the bag when he uses 300 grams.
So he uses 1 bag for 16 days
1 bag can last for 16 days.
Answer:
Jesse should buy a new bag in 16 days

Step-by-step explanation:
A department store buys 200 shirts at a cost of $3,600 and sells them at a selling price of $20 each. Find the percent markup.
Given:
A department store buys 200 shirts at a cost of $3,600 and sells them at a selling price of $20 each.
To find:
The percent markup.
Solution:
A department store buys 200 shirts at a cost of $3,600. So, the cost price of each shirt is
[tex]C.P.=\dfrac{3600}{200}[/tex]
[tex]C.P.=18[/tex]
So, the cost price(C.P.) is $18 each.
The selling price(S.P.) is $20 each.
Now,
[tex]\text{Percent markup}=\dfrac{S.P.-C.P.}{C.P.}\times 100[/tex]
[tex]\text{Percent markup}=\dfrac{20-18}{18}\times 100[/tex]
[tex]\text{Percent markup}=\dfrac{2}{18}\times 100[/tex]
[tex]\text{Percent markup}=\dfrac{1}{9}\times 100[/tex]
[tex]\text{Percent markup}\approx 11.11\%[/tex]
Therefore, the markup percent is 11.11%.

What is the complete factorization of 8x2 − 8x + 2?
A. 2(4x − 1)2
B. 8(x − 1)(x + 1)
C. 2(2x − 1)2
D. 2(x − 2)(x + 2)
Answer:
Step-by-step explanation:
8x^2 - 8x + 2
2(4x^2 - 4x + 1)
2(2x - 1)(2x - 1) or 2(2x - 1)^2
answer is C
The complete factorization of [tex]8x^2 - 8x + 2[/tex] will be [tex]2(2x-1)^2[/tex] .
What is factorization ?Factorization is a process consists of writing a number or another mathematical object as a product of several factors solving it into other factors.
We have,
[tex]8x^2 - 8x + 2[/tex]
Using the mid term splitting method;
[tex]=8x^2-4x-4x+2[/tex]
[tex]=4x(2x-1)-2(2x-1)[/tex]
[tex]=(4x-2)(2x-1)[/tex]
[tex]=2(2x-1)(2x-1)[/tex]
[tex]=2(2x-1)^2[/tex]
So, the factorization of the given expression is given in option [tex](c)[/tex] i.e. [tex]2(2x-1)^2[/tex] .
Hence, we can say that the complete factorization of [tex]8x^2 - 8x + 2[/tex] will be [tex]2(2x-1)^2[/tex] .

X, y and mans shadow length?
Answer:
x = 9.6 meters
y = 20.98 meters
Shadow length = 11.38 meters
Step-by-step explanation:
By applying tangent rule in right triangle ABD,
tan(21)° = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
tan(21) = [tex]\frac{x}{25}[/tex]
x = 25(tan 21)
x = 9.5966
x ≈ 9.60 meters
Similarly, by applying tangent rule in ΔABC,
tan(40)° = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
tan(40)° = [tex]\frac{BC}{AB}[/tex]
tan(40)° = [tex]\frac{y}{25}[/tex]
y = 25(tan 40°)
y = 20.98 meters
Length of the shadow of the man = y - x
= 20.98 - 9.60
= 11.38 meters
