Answer:

Step-by-step explanation:

Take any two points and find the slope.

(3,7) ; (9,5)

Slope =[tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\[/tex]

         [tex]=\frac{5-7}{9-3}\\\\=\frac{-2}{6}\\\\=\frac{-1}{3}[/tex]

Equation: y -y1 = m(x -x1)

[tex]y - 7 = \frac{-1}{3}(x - 3)\\\\y -7 =\frac{-1}{3}x -3*\frac{-1}{3}\\\\y -7=\frac{-1}{3}x+1\\\\y = \frac{-1}{3}x+1+7\\\\y=\frac{-1}{3}x+8[/tex]

Which of the statements is true?

A. For every value of x, the rate of change of f(x) exceeds the rate of change of g(x).

B. As x increases, the rate of change of g(x) exceeds the rate of change of f(x).

C. At approximately x = 4.74, the rate of change of g(x) is equal to the rate of change of f(x).

D. As x increases, the rate of change of f(x) exceeds the rate of change of g(x).

Answers

A statement that is true include the following: B. As x increases, the rate of change of g(x) exceeds the rate of change of f(x).

How to determine the average rate of change?

In Mathematics, the average rate of change of f(x) on a closed interval [a, b] is given by this mathematical expression:

Average rate of change = [f(b) - f(a)]/(b - a)

Next, we would determine the average rate of change of the function f(x) over the interval [0, 1]:

a = 0; f(a) = 1

b = 1; f(b) = 6

By substituting the given parameters into the average rate of change formula, we have the following;

Average rate of change = (6 - 1)/(1 - 0)

Average rate of change = 5/1

Average rate of change = 5

For g(x), we have the following:

Average rate of change = (216 - 0)/(1 - 0)

Average rate of change = 216/1

Average rate of change = 216

If Albert Enstein has 53 socks in his drawer: 21 identical blue, 15 identical black and 17 identical red. The lights are out and he is completely in the dark. How many socks must he take out to make 100 percent certain he has at least one pair of black socks?

Answers

Answer:

6  socks

Step-by-step explanation:

What we must do is calculate the probability of this happening, that he takes out two black socks in the first two taken out.

There are 12 black socks and in total they are 24, therefore the probability of drawing 1 is:

12/24

and now the probability of getting another one is 11 (there is one less outside) and in total they are 23:

11/23

the final probability is the multiplication of these events:

(12/24) * (11/23)

P = 0.24

Now, to know how many you should get, we multiply the probability by the total number of socks, that is:

0.24 * 24 = 5.76

So you must take out at least 6 socks for the above to happen.

the number of socks  Albert Enstein has to take out to be sure that he has at least one pair of black socks is 38.

In order to determine the number of socks  Albert Enstein has to take out to be sure that he has at least one pair of black socks, we would have to add the number of blue socks with the number of red socks.

Number of socks to be taken out = number of blue socks + number of red socks

21 + 17 = 38 socks

question:
1. Use the Pythagorean theorem to find AD.
2. Find AC. Show your work.
3. Is ΔABC a right triangle? Explain.
SHOW YOUR WORK

Answers

Problem 1

Answer: AD = 9

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

Work Shown:

Focus on triangle ADB, which is the smaller triangle on the left.

We have these side lengths

AD = unknown leg

BD = 12 = known leg

AB = 15 = known hypotenuse

Let's apply the Pythagorean Theorem to find the unknown leg

a^2 + b^2 = c^2

(AD)^2 + (BD)^2 = (AB)^2

(AD)^2 + (12)^2 = (15)^2

(AD)^2 + 144 = 225

(AD)^2 = 225-144

(AD)^2 = 81

AD = sqrt(81)

AD = 9

Side AD is 9 units long.

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

Problem 2

Answer: AC = 25

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

Work Shown:

AC = AD + DC .... segment addition postulate

AC = 9 + 16 ..... substitution; refer to problem 1

AC = 25

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

Problem 3

Answer: Triangle ABC is a right triangle.

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

Work Shown:

The Pythagorean Theorem Converse says "if a^2+b^2 = c^2 is a true equation, then the triangle with sides a,b,c is a right triangle". Keep in mind that c is always the longest side (hypotenuse). The order of 'a' and b doesn't matter. Convention has us usually do [tex]a \le b[/tex] but again the order isn't important.

We have these three sides

a = 15 (length of side AB; leg #1)b = 20 (length of BC; leg #2)c = 25 (length of AC; hypotenuse)

Plug those values into the equation below. Simplify each side.

a^2+b^2 = c^2

15^2 + 20^2 = 25^2

225 + 400 = 625

625 = 625

We get a true equation. Therefore, triangle ABC is a right triangle.

Answer:

Step-by-step explanation:

Pythagorean = c^2 =a^2 + b^2

we are given c and a   so solve for b

c^-a^2 = b^2

15^2- 12^ = b^2

81= b^2

[tex]\sqrt{81}[/tex]=b

9=b

AD=b

AC = AD + 16

AC =9 + 16 =25

if it's a right triangle then Pythagorean will work with the sides to make 25

AC^2 = 15^2+20^2

AC = [tex]\sqrt{625}[/tex]

AC = 25
