Step-by-step explanation:
Water is added or drained from a tank each day. The first day, 910 of a gallon is added to the empty tank. The second day, 710 of a gallon is drained from the tank. The third day, 810 of a gallon is added to the tank. The fourth day, 610 of a gallon is drained from the tank. The amount of water in the tank after 15 days is given by 910+(−710)+810+(−610)+⋯+310+(−110)+210 9 10 + ( − 7 10 ) + 8 10 + ( − 6 10 ) + ⋯ + 3 10 + ( − 1 10 ) + 2 10 . How much water is in the tank after 15 days? Write your answer as a decimal. gallon(s)
Answer:
The quantity of water in the tank after 15 days is 1610.0 gallons OR 1.61 × 10³ gallons.
Step-by-step explanation:
The amount of water in the tank after 15 days is given by the series
910+(−710)+810+(−610)+⋯+310+(−110)+210
From the series, we can observe that, if water is added for a particular day then water will be drained the following day.
Also, for a day when water is to be added, the quantity to be added will be 100 gallon lesser than the quantity that was last added. Likewise, for a day when water is to be drained, the quantity to be drained will be 100 gallons lesser than the quantity that was last drained.
Hence, we can complete the series thus:
910+(−710)+810+(−610)+710(-510)+610(-410)+510(-310)+410(-210)+310+(−110)+210
To evaluate this, we get
910-710+810-610+710-510+610-410+510-310+410-210+310-110+210
= 1610.0 gallons
Hence, the quantity of water in the tank after 15 days is 1610 gallons OR 1.61 × 10³ gallons.

0,4 Find the roots of the following quadratic equations
using the quadratic formula
1) 6a²x² - 7abx - 3b²=0, a is not equal to zero
pls answer
Answer:
b = b2-4ac
= (-7ab)^2 -4 (6a^2)(-3b^2)
= 49a^2b^2 + 72a^2b^2
= 121a^2b^2
Now, x = (7ab +- root 121a^2b^2)÷2(6a²)
= (7ab +- 11ab ) ÷ 12a²
= ( 20ab)/12a² or 4ab/12a²
= 5/3ab or - 1/3ab .
So, these are its roots .

HELP ASAPP... Find the volume of a cylinder with a radius of 5 inches and a height that is three times the radius. Use 3.14 for pi and round your answer to the nearest tenth. (Hint: You may only enter numerals, decimal points, and negative signs in the answer blank)
Answer:
1177.5 in³
Step-by-step explanation:
To find the volume of a cylinder, you need to do this:
V= π r² h
Substitute in 3.14, 5, and 15
V= 3.14 x 5² x 15
Multiply 5 by itself
V= 3.14 x 25 x 15
Multiply 3.14 and 25
V= 78.5 x 15
Multiply 78.5 x 15 to get your answer:
V= 1177.5 in³

Answer: The answer provided is correct
Step-by-step explanation:
which subtraction expression does the number line model show
Answer:
13-+4
Step-by-step explanation:
What is the equation of the line that is perpendicular to the line y = 2x+5 and
passes through the point (-4, 2)?
O A. y = -1/2x+2
B. y = 2x + 6
O C. y = 2x-6
O D. y=-1/2x
Answer:
y= -1/2x
Step-by-step explanation:
perpendicular is the opposite slope so -1/2 is the opposite slope of 2y=mx+b to solve for b I was taught to plug in what you have so2= -1/2(-4)+b2=2+bsubtract 2 on both sides to get b=0ASAP PLEASE What is the slope of the blue and green line ( both parallel)
Answer:
slope = - 2
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 8, 4) and (x₂, y₂ ) = (- 1, - 10) ← 2 points on the green line
m = [tex]\frac{-10-4}{-1+8}[/tex] = [tex]\frac{-14}{7}[/tex] = - 2
Repeat with (x₁, y₁ ) = (- 3, 0) and (x₂, y₂ ) = (0, - 6) ← 2 points on the blue line
m = [tex]\frac{-6-0}{0+3}[/tex] = [tex]\frac{-6}{3}[/tex] = - 2
Since the slopes are equal then the lines are parallel
