A company is going to make a water tank in the shape of a cylinder. As shown below, the tank will have a height of 4ft and a radius of 6ft. The tank will be made from metal (including its top and bottom). Suppose the total cost of the metal will be $14,318.40. How much will the metal cost per square foot? Use 3.14 for pi, and do not round your answer.

Step-by-step explanation:

Answer:

b. P = 56,382(1+0.012)^t

The equation that defines the population in Smalltown t years after 2010 is [tex]P = 56,382(1 + 0.012)^t[/tex]

percentage, a relative value indicating hundredth parts of any quantity.

The population P after 2010 is an exponential growth function of the form:

[tex]P = P_{0} (1 + r)^t[/tex]

where P₀ is the initial population,

r is the annual growth rate as a decimal, and

t is the time in years.

Byu given information P₀ = 56,382,

r = 0.012, and

t is the number of years after 2010.

The equation that defines the population in Smalltown t years after 2010 is:

[tex]P = 56,382(1 + 0.012)^t[/tex]

Hence, equation that defines the population in Smalltown t years after 2010 is [tex]P = 56,382(1 + 0.012)^t[/tex]

Answer:

0.753

Step-by-step explanation:

I just took the test lol

The value of log₃(⁷/₁₆) when log₃4 = 1.262 and log₃7 = 1.771 is;

log₃(⁷/₁₆) = -0.753

We are given;

log₃4 = 1.262

log₃7 = 1.771

We want to find log₃(⁷/₁₆)

Now, from properties of logarithm too, we have;

logₐ(x/y) = logₐx - logₐy

Thus;  log₃(⁷/₁₆) =  log₃7 -  log₃16

Also, we know that; logₐx² = 2logₐx

Thus; log₃16 =  log₃4²

log₃16 = 2log₃4

Thus; log₃(⁷/₁₆) = log₃7 - 2log₃4

Plugging in the relevant values gives;

1.771 - 2(1.262) = -0.753

Answer: y = 3

Step-by-step explanation:  

So, we must find an equation of a line that passes through these two points such that we find the slope first as,  

m = (3-3) / (2-(-1)) = 0 / 3 = 0. Then we bring up the point-slope form of an equation to find the line such that  

y - y1 = m(x - x1). Next,  

y - 3 = 0(x - (-1))

y - 3 = 0..............Then add 3 such that the equation of a line is

Answer:

It will be worth $128.

Step-by-step explanation:

After 1 year, 3/5 of 800 is 480 which leaves the value at $320, and then after 2 years, 3/5 of 320 is 192. 320-192 leaves the value at $128.

Answer:Justin plans to spend $20 on sports cards. Regular cards cost $3.50 per pack and foil cards cost $4.50 per pack

number of packs of regular cards =r and the number of packs of foll cards = f

Cost of Regular card = 3.50

Cost of 'r' packs of regular card = 3.50r

Cost of Foil card = 4.50

Cost of 'f' packs of Foil card = 4.50f

Justin plans to spend $20 on sports cards so the sum of cost of regular and Foil cards should be less than or equal to 20

The inequality becomes

3.50r + 4.50f <= 20

Answer:

184

Step-by-step explanation:

f(-9) means find the value of the function when x = -9, so substitute -9 into the function and solve:

3(-9)^2 + 5(-9) - 14

3(81) + 5(-9) - 14

3(81) + (-45) - 14

Answer:

Step-by-step explanation:

Simplifying

5x + -4 = 40

Reorder the terms:

-4 + 5x = 40

Solving

-4 + 5x = 40

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '4' to each side of the equation.

-4 + 4 + 5x = 40 + 4

Combine like terms: -4 + 4 = 0

0 + 5x = 40 + 4

5x = 40 + 4

Combine like terms: 40 + 4 = 44

5x = 44

Divide each side by '5'.

x = 8.8

Simplifying

x = 8.8

C. bisects that chord

Step-by-step explanation:

The radius of a circle is perpendicular to a chord if and only if it bisects the chord. Therefore, the option b is correct.

In the case when the diameter or the radius should be perpendicular with respect to the chord so it should be bisected the chord also its arc.

At the time when the two chords should be congruent so their corresponding arc should also be congruent.

Therefore, the option b is correct.

Answer:

The distance between two cities is 70 km.

Step-by-step explanation:

Given that,

The distance between two cities on a map is 3.5 centimeters.

It is also mentioned that the map uses a scale  in which 1 centimeter represents 20 kilometers.

We need to find the actual distance  between these two cities in kilometers.

1 cm = 20 km

3.5 cm = (3.5 × 20) km

= 70 km

Hence, the distance between two cities is 70 km.
