Answer:
a₁₀₀ = 385Step-by-step explanation:
The nth term of arithmetic sequence is [tex]a_n=a_1+d(n-1)[/tex]
So:
[tex]a_9=a_1+d(9-1)\\\\37=a_1+8d\\\\a_1=37-8d\\\\\\a_{16}=a_1+d(16-1)\\\\65=a_1+15d\\\\65=37-8d+15d\\\\28=7d\\\\d=4\\\\a_1=37-8\cdot4=5\\\\\\a_{100}=a_1+d(100-1)=5+4\cdot95=385[/tex]

k = 12/36
k = 1/3
Answer: k = 1/3
The price of a watch was increased by 20% to £162.
What was the price before the increase?
Answer:
The answer is 135

24.6
Answer:
21.2Step-by-step explanation:
[tex]x\times(x+ 28) = 20\times (20+32)\\\\x^2+28x-1040=0\\\\\ x=\dfrac{-28\pm\sqrt{28^2-4\cdot1\cdot(-1040)}}{2\cdot1}= \dfrac{-28\pm\sqrt{4944}}{2}\\\\x\approx21.2\quad or\quad x\approx-49.2[/tex]
x has to be >0 so the answer is 21.2

Rachel's car has a 12 gallon gas tank and
she uses about 0.5 gallons per day driving to
school. Write an equation describing the
number of gallons of gas, g, Rachel has in
her car and the number of days, d, she has
driven to school.
please help meeee
Answer:
g=dx
Or, if you'r wanting the solved equation..
12 = 0.5 x 24
Step-by-step explanation:
If she has 12 gallons in her tank and you look at what it's asking us to do, "..number of gallons of gas, g" pairs up with the 12 gallons while the 0.5 gallons used per day pairs with "...the number of days, d, she has driven to school."
Hope this helped!

Amanda is pumping water into an aquarium at a rate of 12 liters per minute the aquarium had 42 liters of water in it before she started her goal is given by 13x+42<_234 where x is the number of minutes she pumps water into the aquarium
Answer:
Let x represent minutes.
The inequality derived from the question is...
58 > 18 + 5x
Solve for x...
58 > 18 + 5x
58 - 18 > 5x
40 > 5x
40/5 > x
8 > x
So it will take more than 8 minutes to have 58 liters.

Answer:
4x^2 -3 + 1/x
Where ;
p(x) =( 4x^2 -3) and k = 1
Step-by-step explanation:
Here, we want to divide the given polynomial
To get this, we can use the method of long division
P(x) will be the quotient of the division, while k will be the remainder of the division
We can see the long division used in as seen in the attachment
So, we have the result as;
4x^2 -3 + 1/x
Where ;
p(x) = 4x^2 -3 and k = 1

The function f is given in three equivalent forms.
Which form most quickly reveals the vertex?
Choose 1 answer:
f(x) = 3x^2+ 36x + 33
f(x) = 3(x+6^2-75
f(x)=3(x+1)(x+11)
What is the vertex?
Answer:
Step-by-step explanation:
Look what happens when you factor the 3 out of the first choice:
f(x) = 3x^2+ 36x + 33 = f(x) = 3(x^2+ 12x) + 11
We can "complete the square:" x^2 + 12x becomes x^2 + 12x + 36 - 36, which, in turn, becomes (x + 6)^2 - 36
so that the original f(x) becomes f(x) = 3(x + 6)^2 - 36 + 33, or
f(x) = 3(x + 6)^2 - 3
Comparing this to
f(x) =a(x - h)^2 + k reveals that h = -6 and k = -3. Thus, the vertex is at (-6, -3).
