An object is dropped from a height of 150 feet. Its heights s at time, t is given by the

equation s(t) =-16t^2+150 ,where s is measured in feet and t is measured in seconds.

Find the average rate of change of the height over the interval [1, 2.5).

O 1) -56 ft/sec

O2) 77 ft/sec

03) 56 ft/sec

O4) -35 ft/sec

Answers

Answer:

The average rate of change of the height over the interval [1, 2.5] is - 56 feet per second.

Step-by-step explanation:

Let [tex]s(t) = -16\cdot t^{2} + 150[/tex]. Geometrically speaking, average rate of change over a given interval ([tex]\bar v[/tex]), measured in feet per second, is determined by definition of secant line, which is defined:

[tex]\bar v = \frac{s(t_{2})-s(t_{1}) }{t_{2}-t_{1}}[/tex] (1)

Where:

[tex]s(t_{1})[/tex], [tex]s(t_{2})[/tex] - Initial and final position of the object, measured in feet.

[tex]t_{1}[/tex], [tex]t_{2}[/tex] - Initial and final times, measured in seconds.

If we know that [tex]t_{1} = 1\,s[/tex] and [tex]t_{2} = 2.5\,s[/tex], then the average rate of change over the interval [tex][1,2.5][/tex]:

[tex]s(1) = -16\cdot (1)^{2}+150[/tex]

[tex]s(1) = 134[/tex]

[tex]s(2.5) = -16\cdot (2.5)^{2}+150[/tex]

[tex]s(2.5) = 50[/tex]

[tex]\bar v = \frac{50\,ft-134\,ft}{2.5\,s-1\,s}[/tex]

[tex]\bar v = -56\,\frac{ft}{s}[/tex]

The average rate of change of the height over the interval [1, 2.5] is - 56 feet per second.

Verify [(1+tanx)/sinx] - secx = cscx. Show your work and identities you used.

Answers

Answer:

let's start.

Step-by-step explanation:

                         [tex]\frac{(1+tanx)}{sinx} -secx = cscx\\[/tex]

we can write it as

                        [tex]\frac{(1 + tanx)}{sinx} = cscx + secx[/tex]

starting with left hand side

LHS    

       [tex]\frac{(1 + tanx)}{sinx}[/tex]

      [tex]\frac{1}{sinx} + \frac{tanx}{sinx}\\\\cscx + tanx *\frac{1}{sinx}\\\\cscx + \frac{sinx}{cosx} *\frac{1}{sinx}\\\\cscx + \frac{1}{cosx}\\\\cscx + secx[/tex]  

       

∴ LHS = RHS

hence,   proved        

Answer:

See below

Step-by-step explanation:

(1 + tanx)/sinx - secx = cscx1/ sinx + tanx/ sinx - 1/cosx = cscx1/ sinx + sinx/ cosx × 1/sinx - 1/ cos x = cscx1/ sinx + 1/cosx - 1/cosx = cscx1/ sinx  = cscxcscx = cscx

Nick spent 34 minutes on the phone while routing 17 phone calls. In all, how many phone calls does Nick have to route to spend a total of 50 minutes on the phone? Assume the relationship is directly proportional.

Answers

Answer:

25 phone calls

Step-by-step explanation:

Create a proportion where x is the number of phone calls for 50 minutes on the phone:

[tex]\frac{34}{17}[/tex] = [tex]\frac{50}{x}[/tex]

Cross multiply and solve for x:

34x = 850

x = 25

So, Nick would have to make 25 phone calls

you and a friend fill balloons with water. Two out of every 25 balloons pop while being fillied what percent of the balloons do not pop while they are being fillied

Answers

Answer:

92 percent

Step-by-step explanation:

Answer:

92% of balloons filled did not pop.

Step-by-step explanation:

2 / 25 balloons is the fraction of balloons that do pop, and we want the percentage that don't pop.

To start off with, we will get the fraction of balloons that don't pop - 23 / 25.

We will then convert this fraction to a decimal by dividing the fraction:

23 divided by 25 = 0.92

Now, to convert this to a percentage, we just multiply by 100.

0.92 x 100 = 92%

Therefore the answer is 92% of balloons filled did not pop.

Mckenzie's Work Cara's Work

a2 + b2 = c2 a2 + b2 = c2

52 + 132 = c2 52 + b2 = 132

25 + 169 = c2 25 + b2 = 169

194 = c2 b2 = 144

Square root 194 equals square root c squared. Square root b squared equals square root 144.

13.93 ≈ c b ≈ 12
Who is right?

Answers

Answer:

Makenzie is correct,  13.93 ≈c

Step-by-step explanation:

the sides with determined lengths (see image) are A (13) and B (5). C however is not determined.

the correct equation would be to solve for c.

13² + 5² = c²

[tex]\sqrt {169 + 25} = c[/tex]

c ≈ 13.93

Clara solved for b and not c, which is incorrect.

The right working is as follows:

c² = a² + b²

c² = 5² + 13²

Using Pythagoras theorem,

c² = a² + b²

where

c = hypotenuse

a and b are the other two legs.

Therefore,

c = ?

a = 5

b = 13

c² = 5² + 13²

c² = 25 + 169

c² = 194

c = √194

c = 13.9283882772

c = 13.9 inches
