1) What percent of the time did Main Street have 100 or more cars per hour?

Answers

The box plot represents the rate of cars in the Main Street per hour

25 percent of the time, the Main Street have 100 or more cars per hour

How to determine the proportion of the boxplot?

From the box plot, we have the following parameter:

The upper quartile of the boxplot is 100

This means that:

Q3 = 100

The upper quartile is the 75% dataset

The actual percentage is then calculated as:

Actual = 100% - 75%

This gives

Actual  = 25%

Hence, 25 percent of the time, the Main Street have 100 or more cars per hour

The numbers in this sequence increase by 40 each time 30, 70, 110, 150. The sequence is continued with the same rule. Which number in the sequence will be closest to 300?

Answers

The value in the sequence closest to 300 is 310

Arithmetic Sequence

Arithmetic sequence is a sequence where each term increases or decreases by addition or subtraction of a constant term

the first term a = 30

common difference, d = 40

which term is closest to 300 we solve like this

300 / 40 = 7.5 say 7

the 7th term, T7 is solved by

T7 = a + ( n - 1 ) d

T7 = 30 + ( 7 - 1 ) 40

T7 = 30 + 240

T7 = 270

checking for the 8th term to confirm the nearest

T8 = T7 + d = T7 + 40

T8 = 270 + 40

T8 = 310

therefore the 8th term is closest and the value is 310

Amount at the year end

The Amount accumulated at the end of a interest year is the sum of the principla amount and the interest gained on the principal amount.

How to find amount at the end of interest year?

As Andres start the savings account after 3 years so, the equation representing the value of Andre's account after t years is-[tex]v_h=500(1.025)^{t-3}[/tex].

Also, the amount accumulated in the mean 3 years will be-

d. What is the height of the ball after 1 second?
(THIS IS A 4 PART QUESTION, PLEASE DO ALL PARTS!!!) PLEASE GIVE INDEPTH EXPLANATION FOR ALL PARTS!

Answers

Answer:

(a)  144 ft

(b)  2 s

(c)  5 s

(d)  128 ft

Step-by-step explanation:

[tex]h(t) = -16t^2 + 64t + 80[/tex]

Part (a)

To find the turning point of the parabola:

1. differentiate the function:

[tex]\implies h'(t) = -32t + 64[/tex]

2. Set it to zero and solve for t:

[tex]\implies h'(t) =0[/tex]

[tex]\implies -32t + 64=0[/tex]

[tex]\implies 32t = 64[/tex]

[tex]\implies t=2[/tex]

3. Input found value of t back into the function and solve for h:

[tex]\implies h(2) = -16(2)^2 + 64(2) + 80=144[/tex]

Therefore, the maximum height reached by the ball is 144 ft

Part (b)

As found in part (a), the maximum height is reached when t = 2, so the ball reached its maximum height at 2 seconds.

Part (c)

The ball will hit the ground when h(t) = 0

1. Set the function to zero

[tex]\implies h(t)=0[/tex]

[tex]\implies -16t^2 + 64t + 80=0[/tex]

2. Solve for t:

Divide both sides by 16

[tex]\implies -t^2 + 4t + 5=0[/tex]

[tex]\implies t^2 - 4t - 5=0[/tex]

Factor:

[tex]\implies t^2 +t-5t - 5=0[/tex]

[tex]\implies t(t+1)-5(t+1)=0[/tex]

[tex]\implies (t+1)(t-5)=0[/tex]

Therefore:

[tex](t+1)=0 \implies t=-1[/tex]

[tex](t-5)=0 \implies t=5[/tex]

As time is positive, t = 5

So the ball will hit the ground at 5 seconds.

Part (d)

To find the height of the ball after 1 second, input t = 1 into the function and solve for h:

[tex]\implies h(1) = -16(1)^2 + 64(1) + 80=128[/tex]

Therefore, the height of the ball after 1 second is 128 ft

--------------------------------------------------------------------------------------

Parts (a) & (b) - alternative method

Rewrite the function in vertex form by completing the square.

Set the function to zero:

[tex]\implies-16t^2 + 64t + 80=0[/tex]

Subtract 144 from both sides:

[tex]\implies -16t^2+64t-64=-144[/tex]

Factor out -16:

[tex]\implies -16(t^2 - 4t +4)=-144[/tex]

Factor expression in brackets:

[tex]\implies -16(t-2)^2=-144[/tex]

Add 144 to both sides:

[tex]\implies -16(t-2)^2+144=0[/tex]

Therefore:

[tex]\implies h(t)=-16(t-2)^2+144[/tex]

The maximum height is the y-value of the vertex.

The vertex is (2, 144) so the maximum height is 144 ft.

The time the ball reached the max height is the x-value of vertex.

So the time then the ball reached the maximum height is 2 s

their sum is -11 and difference is 41

What is the value of x?



Enter your answer in the box.

Answers

Answer:

x = 4

Step-by-step explanation:

x has the same value as RT since they are equal sides of the isosceles triangle.

RT is also the hypotenuse of ΔRST - 30°×60°×90° right triangle.

Acoording to the property of such triangles, the ratio of sides is:

a : b : c = 1 : √3 : 2

We have:

b = 2√3 and c = RT

Use the ratio to find the lenght of RT

2√3 : RT = √3 : 2RT = 2*2√3/√3RT = 4

So the value of x is 4 units

Find RT

sin60=2√3/RT√3/2=2√3/RTRT=4√3/√3RT=4

Now

Find the equation of the line that
is perpendicular to y = -2x - 9 and
contains the point (8, -4).

Answers

Answer:

[tex]y=\frac{1}{2} x-8[/tex]

Step-by-step explanation:

The final answer is in the slope-intercept form, which is y=mx +c, where m is the slope and c is the y-intercept.

The slope of a perpendicular line is the negative reciprocal of the slope of the given line (the line it is perpendicular to). Thus, let's find the slope of the given line first.

Given line: y= -2x -9

The above equation is already in the slope-intercept from and thus, the slope is the coefficient of x.

Slope of given line= -2

The coefficient is the number that comes before a variable and it includes the positive or negative sign, which explains why the slope of the given line is -2 instead of 2.

Slope of perpendicular line= [tex]\frac{1}{2}[/tex]

Substitute the value of the slope into the equation:
[tex]y=\frac{1}{2} x+c[/tex]

To find the value of c, substitute a pair of coordiantes the line passes through.

When x= 8, y= -4,

[tex]-4=\frac{1}{2}(8)+c[/tex]

-4= 4 +c

c= -4 -4

c= -8

Thus, the equation of the perpendicular line is [tex]\bf{y=\frac{1}{2} x-8}[/tex].

What is reciprocal?

The reciprocal of a number is 1 divided by that numberFor example, the reciprocal of 2 is [tex]\frac{1}{2}[/tex]In this question, we are interested in negative reciprocal. This means that if the slope of the given line is m, the slope of the perpendicular line is [tex]-\frac{1}{m}[/tex].

Improving water efficiency reduces operating costs (e.g., pumping and treatment) and reduces the need to develop new supplies and expand our water infrastructure. It also reduces withdrawals from limited freshwater supplies, leaving more water for future use and improving the ambient water quality and aquatic habitat. More and more utilities are using water efficiency and consumer conservation programs to increase the sustainability of their supplies. Case studies demonstrate substantial opportunities to improve efficiency through supply-side practices, such as accurate meter reading and leak detection and repair programs, as well as through demand-side strategies, such as conservation-based water rates and public education programs.Supply-Side Strategies for Water Suppliers Accounting for WaterAccounting for water is an essential step toward ensuring that a water utility is sustainable. This is best accomplished when water systems meter use by their customers. Metering helps to identify losses due to leakage and also provides the foundation on which to build an equitable rate structure to ensure adequate revenue to operate the system. Water Loss ControlNational studies indicate that, on average, 14 percent of the water treated by water systems is lost to leaks. Some water systems have reported water losses exceeding 60 percent. Accounting for water and minimizing water loss are critical functions for any water utility that wants to be sustainable. Demand-Side Strategies for Water Suppliers Water RatesOne of the most effective ways to reduce demand for water is to establish rates that escalate as more water is used. Consumer EfficiencyConsumers can reduce water use by installing water-efficient products or employing efficiency practices, such as turning the water off while brushing teeth or running washing machines only when they are full. Water systems can promote these actions through consumer rebate and education programs. EPA's WaterSense ProgramWaterSense seeks to protect the future of our nation's water supply by promoting water efficiency and enhancing the market for water-efficient products, programs, and practices. Visit the website for information on water-efficient products and practices, as well as utilities who offer rebates for WaterSense labeled products. Water systems can also apply to become a WaterSense program partner and receive tools they can use to promote their own water efficiency programs.implement -- to put in placeinfrastructure -- the physical structures necessary for a system to operateambient -- existing; already presentrevenue -- earned money or incomeQuestion 1Part AWhich structure does the author use to organize information in the text Water Efficiency Strategies?The author shares chronological instructions for managing water efficiency.The author compares and contrasts multiple water efficiency systems and practices.The author provides several solutions for efficient and sustainable water systems.The author explains events that caused a need for water efficiency systems.Question 2Part BHow does the section "Supply-Side Strategies for Water Suppliers" contribute to the structure and organization identified in Part A?It debates whether water loss control or accounting for water is more effective to achieve efficiency.It describes how and when water meters were first used to measure water usage.It provides detailed instructions for using a water meter and locating where leaks are most likely to occur.It explains how accounting for water and water loss control are methods to achieve sustainability.
