2 1/2 * 5/8 = ?
2 1/2 * 8/5 =?
2 1/2 ÷ 5/8 = ?

Answers

Answer 1

Answer:

c

Step-by-step explanation:

The answer is c

Answer 2

Answer:

5/8 * ? = 2 1/2

Step-by-step explanation:

x is the height of tower when finished.

We know that Priya takes a break when the tower is 2 and 1/2 feet tall, which is 5/8 off the height of the tower she wants to build.

This means that 5/8 of x equals 2 and 1/2 Let us represent this information in an equation.

5/8 × x = 2 and 1/2

Convert our given mixed fraction into improper fraction.

5/8 × x = 5/2

Multiply both sides of our equation by 8/5.

(8/5 × 5/8) × x = (5/2 × 8/5)

x = 8/2

x = 4

4 feet

A behavioral economist studies transportation habits in an urban center. She identifies 4 bus routes that connect to 3 different light rail routes available to participants in the study. Before she interviews participants, she must determine the number of possible routes participants can choose to use. Which expression represents the number of available options

a. 4!+3!
b. 4×3
c.4!×3!
d. 4!/3!

Answers

Answer:

Total possible routes participants can choose = 4×3 = 12 ways

The correct option is - b. 4×3

Step-by-step explanation:

Given - A behavioral economist studies transportation habits in an

            urban center. She identifies 4 bus routes that connect to 3

            different light rail routes available to participants in the study.

To find - Before she interviews participants, she must determine the

              number of possible routes participants can choose to use.

              Which expression represents the number of available options.

Proof -

Given that ,

Total bus routes = 4

So, number of possible ways she use the bus route = 4

Also,

The 4 bus route connects to 3 different light rail

So, possible ways that she use light rail = 3

∴ we get

Total possible routes participants can choose = 4×3 = 12 ways

The correct option is - b. 4×3

Answer:

  x ≈ 0.309906932381 or 4

Step-by-step explanation:

There are no algebraic methods of solving a mixed exponential and polynomial equation. The value of x can be found by guessing, or by other means such as trial and error or graphing.

Attached is a graph showing two solutions. x = 4 is the integer solution (2^4 = 4·4). The irrational solution is approximately x ≈ 0.309906932381. That precision is obtained by Newton's method iteration, easily done by a graphing calculator.

Find the amplitude and the period of the graphed function; please show work or steps.

Answers

Answers:

Amplitude = 2Period = 5pi/2

===========================================

Explanation:

The lowest point occurs when y = -2. The highest point occurs when y = 2.

The vertical distance between the highs and lows is 4 units (since 2-(-2) = 2+2 = 4). This cuts in half to get 4/2 = 2.

The amplitude is 2. It measures the vertical distance from the midline to either the peaks or valleys.

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

Note that this curve has two lowest points and one highest point shown. What we'll do is shift the graph over to the right so that each of those lowest points snap to a grid point. The lowest point on the left will move to where x = -pi, while the lowest point on the right snaps to x = 3pi/2. We'll keep each point at the same y coordinate.

The horizontal distance from x = -pi to x = 3pi/2 is

(3pi/2) - (-pi) = 3pi/2 + 2pi/2 = 5pi/2

This represents the horizontal distance from the left valley point to the right valley point. This is one full period of the curve. After we arrive at the right valley point, we repeat the process of going up and coming back down in this exact same fashion. The process is repeated forever to generate the cosine curve. The curve repeats itself every 5pi/2 units along the x axis.

Side note: any phase shift of a curve will have the same period as the original curve. This is why we're allowed to shift left or right to help find the period.

Answer:

Triangle a: 44.7°

Triangle b: 30.5°

Triangle c: 67.4°

Triangle d: 56.6°

Step-by-step explanation:

Recall: SOHCAHTOA

a. Reference angle = [tex] \theta [/tex]

Opposite = 19

Hypotenuse = 27

Apply SOH:

[tex] sin(\theta) = \frac{Opp}{Hyp} [/tex]

[tex] sin(\theta) = \frac{19}{27} [/tex]

[tex] \theta = sin^{-1}(\frac{19}{27}) [/tex]

[tex] \theta = 44.7 degrees [/tex] (nearest tenth)

b. Reference angle = [tex] \theta [/tex]

Opposite = 33

Adjacent = 56

Apply TOA:

[tex] tan(\theta) = \frac{Opp}{Adj} [/tex]

[tex] tan(\theta) = \frac{33}{56} [/tex]

[tex] \theta = tan^{-1}(\frac{33}{56}) [/tex]

[tex] \theta = 30.5 degrees [/tex] (nearest tenth)

c. Reference angle = [tex] \theta [/tex]

Opposite = 12

Adjacent = 5

Apply TOA:

[tex] tan(\theta) = \frac{Opp}{Adj} [/tex]

[tex] tan(\theta) = \frac{12}{5} [/tex]

[tex] \theta = tan^{-1}(\frac{12}{5}) [/tex]

[tex] \theta = 67.4 degrees [/tex] (nearest tenth)

d. Reference angle = [tex] \theta [/tex]

Hypotenuse = 20

Adjacent = 11

Apply CAH:

[tex] cos(\theta) = \frac{Adj}{Hyp} [/tex]

[tex] cos(\theta) = \frac{11}{20} [/tex]

[tex] \theta = cos^{-1}(\frac{11}{20}) [/tex]

[tex] \theta = 56.6 degrees [/tex] (nearest tenth)

Thermal energy storage systems commonly involve a packed bed of solid spheres, through which a hot gas flows if the system is being charged, or a cold gas if it is being discharged. In a charging process, heat transfer from the hot gas increases thermal energy stored within the colder spheres; during discharge, the stored energy decreases as heat is transferred from the warmer spheres to the cooler gas. Consider a packed bed of 75-mm-diameter aluminum spheres (p = 2,700 kg/m^3; c = 950 J/kg*K; k = 240 W/m*K) and a charging process for which gas enters the storage unit at a temperature of 300 degrees C. The initial temperature of the spheres is Ti = 25 degrees C and the convection heat transfer coefficient is h = 75 W/m^2*K.a. How long does it take a sphere near the inlet of the system to accumulate 90% of the maximum possible thermal energy? What is the corresponding temperature at the center of the sphere?b.
