The monthly water bill is a function of the number of gallons used. The cost is $19.50 for 20,000 gal or less. Over 20,000 gal, the cost is $19.50 plus $1 for each
1000 gal over 20,000 with any fraction of 1000 gal charged at a fraction of $1. On what interval is the cost constant? On what interval is the cost increasing?
Answer:
Constant: [0,20000]
Increasing: (20000, ∞)

Find the distance between the two points rounding to the nearest tenth! PLEASE HELP ASAP!!!
Answer:
10
Step-by-step explanation:
d =√[(-3+9)²+(6+2)²]
= √(6²+8²)
=√(36+64)
=√100
= 10
Answer:
[tex]\boxed {\boxed {\sf d=10}}[/tex]
Step-by-step explanation:
The distance between two points can be calculated using the following formula.
[tex]d= \sqrt{(x_2-x_1)^2+(y_2-y_1)^2[/tex]
In this formula, (x₁, y₁) and (x₂, y₂) are the two points. We are given the points (-9, -2) and (-3,6). If we match the value with the corresponding variable we see that:
x₁= -9 y₁= -2 x₂= -3 y₂= 6Substitute the values into the formula.
[tex]d= \sqrt {(-3 - -9)^2 + (6 - -2)^2[/tex]
Solve inside the parentheses. Remember that 2 back to back negative signs become a plus sign.
(-3 - -9)= (-3+9)= 6 ( 6- -2)= (6+2) =8[tex]d= \sqrt{ (6)^2 + (8)^2[/tex]
Solve the exponents. Multiply the number by itself.
(6)²= 6*6= 36 (8)²= 8*8= 64[tex]d= \sqrt{(36)+(64)[/tex]
Add.
[tex]d= \sqrt{100[/tex]
Take the square root of the number.
[tex]d= 10[/tex]
The distance between the points (-9, -2) and (-3, 6) is 10.

Answer:
Step-by-step explanation:
The revenue function is given to you, it's just not given in equation form. In equation form, the function is
R(p) = p(120 - 4p)
If we are looking for the number of tickets that causes the revenue to be $0, we replace R(p) with 0 and solve for p.
0 = p(120 - 4p). That means, by the Zero Product Property, that
p = 0 or 120 - 4p = 0 which gives us, when we solve each one of those equations, that
p = 0 or
120 = 4p and
p = 30. The reasoning is the bold statement up above.
The equation we would use to determine the number of tickets needed to sell for the revenue to be $600 will be
600 = p(120 - 4p)

Answer:
c³ + 24c² + 192c + 512
Step-by-step explanation:
(c + 8)³
= (c + 8)(c + 8)(c + 8) ← expand last 2 factors using FOIL
= (c + 8)(c² + 16c + 64)
Multiply each term in the second factor by each term in the first factor
c(c² + 16c + 64) + 8(c² + 16c + 64) ← distribute parenthesis
= c³ + 16c² + 64c + 8c² + 128c + 512 ← collect like terms
= c³ + 24c² + 192c + 512

Carson buys eggs and lemons at the store.
He pays a total of $39.62.
He pays $6.74 for the eggs.
He buys 8 bags of lemons that each cost the same amount.
Which equation could be used to determine xx, how much each bag of lemons costs?
Answer: 8x = $39.62 - $6.74
Step-by-step explanation:
Cost of 1 bag of lemons = $x
Cost of 8 bags of lemons = 8*x = 8x
Cost of 8 bags of lemons = Total cost - cost of the egg
8x = $39.62 - $6.74
Find the conjugate of
7-3i
8+2i
Find the product and conjugate of
4-i
6+3i
(I am not asking for just the answer I would also like to know how you got that answer)
Answer:
see below
Step-by-step explanation:
To find the conjugate of a+bi take the opposite of bi so it would be a - bi
7-3i, the conjugate is 7 + 3i
8+2i the conjugate is 8 -2i
The product of a number and its conjugate is
(a+bi) (a-bi) = a^2 +abi-abi -b^2 i^2 = a^2 - b^2 (-1) = a^2 + b^2
( 4-i) ( 4+i) = 4^2 + 1^2 = 16+1 = 17
( 6+3i)(6-3i) = 6^2 + 3^2 = 36+9 = 45
#1
z=7-3i[tex]\\ \sf\longmapsto \overline{z}=7+3i[/tex]

z=8+2i[tex]\\ \sf\longmapsto \overline{z}=8-2i[/tex]

The ratio of the loudness of lala's earphones to the loudness of polina's earphones to the loudness of goffy's earphones is 6:5:3. if polina's earphones have a loudness of 90 decibels, find the total loudness of all three earphones.
Answer: 252 decibels
given:
6:5:3 = ratio of L to P to G
P=90
one unit is 90/5 because the five represents a smaller version of 90
one unit = 18
answer=18(6+5+3)=252

A rectangular block of fin is 0.5 m long and 0.0lm thick Find the width of the block if its mass and density are 0.45 kg and 9000kgm-³ respectively
Answer:
Step-by-step explanation:
This is going to give you a preposterous answer. The width is into the millions.
density = 9000 kg / m^3
mass = 0.45 kg
V = density / mass
V = 9000 / 0.45 = 20000 m^3
V = L *w * h
L = 0.5 m
h = 0.01 m
w = ?
20000 = 0.5 * 0.01 * w
20000 / (0.5 * 0.01) = w
w = 4000000 m

Which is the better buy?
3-gallon jug of water for $10.92
8-quart jug of water for $8.64
Answer:
3-gallon jug of water for $10.92, is the better buy
Step-by-step explanation:
First let's do the 3 gallon jug -
We need to find the unit rate (The cost per gallon/quart)
$10.92 / 3 = $3.64
$8.64 / 8 = $1.08
1 Gallon = 4 Quarts, therefore the 3-gallon jug of water is the better buy.

6) Two numbers have a sum of 15 and a product of 26. What are they?
Answer:
2 and 13
Step-by-step explanation:
2+13=15
and
2x13=26
[tex]\large \mathfrak{Solution : }[/tex]
let the numbers be x and y
now, we know that
x + y = 15 - Equation (1)xy = 26 - Equation (2)by squaring Equation (1) :
(x + y)² = 15²x² + y² + 2xy = 225x² + y² - 2xy + 4xy = 225(x - y)² + (4 × 26) = 225(x - y)² + 104 = 225(x - y)² = 225 - 104(x - y)² = 121x - y = 11 x = 11 + y - Equation (3)
Plugging the value of x from Equation (3) into Equation (1)
x + y = 1511 + y + y = 152y = 15 - 11y = 4 ÷ 2y = 2 - Equation (4)now, let's plug the value of y from Equation (4) into Equation (3) :
x = 11 + yx = 11 + 2x = 13Please help!!!!!!!!!!!!!!!!!!!!!!!
Step-by-step explanation:
11. Angle A and B are supplementary (add to 180)
And measure of Angle A is 2x+30 and measure of angle B is 6x-12. All you have to do is make an algebraic expression.
180= (2x+30) + (6x-12)
Then just combine like terms and you get
8x+18=180.. Subtract 18 and you get
8x=162 then divide by 8 and you get
X=20.25
Then plug in the number and you get
180=(2*20.25+30)+(6×20.25-12)
Which is is transferred to
180=(70.5) +(109.5)
Which is 180=180.
The measure of angleA is 70.5°
You can try the other's if you want if not then
9. Value of x is 33.5
10. Measure of angleB 90°
12. Measure of angleA 24°
