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.

Answer: 2(8a+5)

To factor means to find a number that can divide all the terms in the expression and leave whole number quotients. The factor is written outside the bracket while the quotients are written inside the bracket. In the question, 2 can divide both 16a and 10 giving 8a and 5. This is how the answer was obtained.

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

Answer:

Given that,

Height of dougal is 1.84 meters and height of seb is 1.7 meters. We need to find the height of dougal as a fraction of the height of seb.

Let x is height of dougal as a fraction of the height of seb. So,

If we divide 1.7 on both sides of above equation, then,

On removing decimal, we get,

Hence, this is the required solution.

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.

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
