Answer:

3

Step-by-step explanation:

The average rate of change of f(x) in the closed interval [ a, b ] is

[tex]\frac{f(b)-f(a)}{b-a}[/tex]

here [ a, b ] = [ 0, 2 ] and from the graph

f(b) = f(2) = 0

f(a) = f(0) = - 6, hence

average rate of change = [tex]\frac{0-(-6)}{2-0}[/tex] = [tex]\frac{6}{2}[/tex] = 3

(-4 + 7i)(-4 - 7i)

= 16 - 49i2

Since i = √-1,

16 - 49i2

= 16 + 49

= 65

Answer:  65

Step-by-step explanation:

   (-4 + 7i)(-4 - 7i)

= -4(-4 - 7i)  +7i(-4 - 7i)

=  16 + 28i    -28i - 49i²

=  16                     - 49(-1)         Note: i² = -1

= 16 + 49

Answer:

C

Step-by-step explanation:

Basically (f+g)(x) = f(x)+g(x).

Following this rule you combine like terms.

7x-2x=5x and 10+5 = 15.

Therefore the answer is C.

f(x) = 10 - 2x

g(x) = 7x + 5

(f + g) (x) = (10 - 2x) + (7x + 5) //Adding two functions

= 10 - 2x + 7x + 5

= 15 + 5x

Answer: C.

Answer:

14

Step-by-step explanation:

This can be solved by writing 2 equations and solving simultaneously.

Let number of Adult tickets be A, and number of child tickets be C.

"Bob bought 24 hockey tickets":

[tex]A+C=24[/tex]

"Adult tickets cost $5.50, and child tickets cost $2.00...Bob bought 24 hockey tickets for $83":

[tex]5.5A+2C=83[/tex]

Now we can solve the first equation for A and substitute in 2nd equation and get the value of C.

A + C = 24

A = 24 - C

Now,

5.5 A + 2 C = 83

5.5 (24 - C) + 2C = 83

132 - 5.5C + 2C = 83

-3.5 C = 83 - 132

-3.5C = - 49

C = 14

Hence, Bob bought 14 child tickets

[tex] {p}^{2} q + {r}^{2} - pqr - pr \\ = pq(p - r) - r(p - r) \\ = (pq - r)(p - r)[/tex]

Answer:

(p - r)(pq - r)

Step-by-step explanation:

P = p²q + r² – pqr – pr  

Rewrite the equation in descending orders of p and increasing orders of r.

P = p²q - pqr - pr + r²

Factor the first two and the last two terms

P = pq(p - r) - r(p - r)

Remove the common factor

P = (p - r)(pq - r)

Answer:

AB = 12.99

Step-by-step explanation:

To answer this problem, use the breast theorem.

[tex]\frac{sinA}{a} = \frac{sinC}{c}[/tex]

The side opposite angle C is denoted by the letter c. It is also denoted as AB side

We know that:

A = 80.4°

a = 17

C = 48.9

Then we have that:

[tex]\frac{sin(80.4\°)}{17} = \frac{sin(48.9\°)}{c}[/tex]

Now clear the variable c from the equation

[tex]c = \frac{sin(48.9\°)}{\frac{sin(80.4\°)}{17}}[/tex]

[tex]c = 12.99[/tex]

Answer:

B

Step-by-step explanation:

Chords which intersect have segments whose products are equal. This means the chord with lengths 5 and x has a product 5x. It is equal to the the other chords lengths 5.1 and 9 as a product 5.1*9.

5x = (5.1)(9)

5x = 45.9

x = 9.18

9.18 rounds to the tenth place as 9.2

Final answer:

To factor 1/7 out of 1/7x+46/7, you can factor it out of each term separately and then combine like terms.

Explanation:

To factor 1/7 out of 1/7x+46/7, you can factor it out of each term separately. So you would have:

1/7(1/7x) + 1/7(46/7)

Simplifying each term gives us:

1/49x + 1/49(46)

Finally, you can combine like terms to get the answer:

1/49x + 46/49

Hence, the number of ways of doing so is:

                                780 ways.

Step-by-step explanation:

We know that if we have to choose r items out of a total of 'n' items then the number of ways of doing so is calculated by the formula of combination as:

                             [tex]n_C_r[/tex]

which is given by:

[tex]n_C_r=\dfrac{n!}{r!\times (n-r)!}[/tex]

Here we have to chose 2 books out of a shelf of 40 books.

i.e. we have: n=40 and r=2

Hence, the number of ways of doing so is:

[tex]{40}_C_{2}=\dfrac{40!}{2!\times (40-2)!}\\\\\\{40}_C_2=\dfrac{40!}{2!\times 38!}\\\\\\{40}_C_2=\dfrac{40\times 39\times 38!}{2!\times 38!}\\\\\\{40}_C_2=\dfrac{40\times 39}{2}\\\\\\{40}_C_2=780[/tex]

            Hence, the answer is:

                   780

In mathematics, the concept of combinations is used when selecting items from a larger group where order doesn't matter. Using the combination formula, we find that there are 780 ways to select 2 books from a shelf of 40 books.

The question pertains to the concept of combinations in mathematics. When you're selecting items, such as books, from a larger group and the order in which you select them doesn't matter, you are dealing with combinations. In this case, you are choosing 2 books from a selection of 40, and the order in which you select them doesn't matter.

To solve this, we use the combination formula nCr = n! / [(n-r)! r!], where 'n' represents the total number of items, 'r' is the number of items to choose, and '!' denotes factorial. In this scenario, n = 40 (total number of books) and r = 2 (number of books to select).

So, substituting these into the formula, we get 40C2 = 40! / [(40-2)! 2!] = (40*39) / (2*1)= 780.

Therefore, there are 780 ways to select 2 books from 40.

4.5x + -7 = 20

Reorder the terms:

-7 + 4.5x = 20

Solving

-7 + 4.5x = 20

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '7' to each side of the equation.

-7 + 7 + 4.5x = 20 + 7

Combine like terms: -7 + 7 = 0

0 + 4.5x = 20 + 7

4.5x = 20 + 7

Combine like terms: 20 + 7 = 27

4.5x = 27

Divide each side by '4.5'.

Final answer:

To find the total cost of the candy Jessica bought, we multiply the quantity (12 pieces) by the price per piece ($0.65) to get a total of $7.80 spent.

Explanation:

Jessica bought 12 pieces of candy at the store for $0.65 each. To find out how much she spent in all on the candy, we simply multiply the number of pieces of candy by the price per piece.

Using the equation:
total cost = (number of pieces) × (price per piece),
we get:
total cost = 12 × $0.65.

By doing the multiplication, we find that:
total cost = $7.80.

Therefore, Jessica spent $7.80 on the 12 pieces of candy.

n = 15

k = 7

Now let's plug it in.

[tex]_{n}C_{k}=\dfrac{n!}{k!(n-k)!}[/tex]

[tex]_{15}C_{7}=\dfrac{15!}{7!(15-7)!}[/tex]

Yes, the ramp is indeed a right triangle.

Final answer:

The triangle with sides of 9 inches, 40 inches, and 41 inches is a right triangle, as it satisfies the Pythagorean theorem (9² + 40² = 41²).

Explanation:

A student asked if a ramp with a triangular cross-section and side lengths of 9 inches, 40 inches, and 41 inches is a right triangle. To determine this, we can use the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

For the triangle in question, if we square each of the side lengths and add the squares of the shorter sides, we should get the square of the longest side if it is indeed a right triangle:

Then add the squares of the two shorter sides:

81 + 1600 = 1681

Since 1681 equals 41², the triangle with sides of 9 inches, 40 inches, and 41 inches satisfies the Pythagorean theorem, confirming it is a right triangle.

Answer:

Helio is 53.2 feet from the kite ⇒ the last answer

Step-by-step explanation:

* Lets change this story problem to a trigonometry problem

- Assume that there is a triangle joining between the

 kite, Farimah and Helio

- The name of the triangle is KFH, where K position of the kite,

 F position of Farimah and H is the position of Helio

∵ Farimah and Helio are standing 15 feet apart from each other

∴ FH = 15 feet

∵ Farimah is flying the kite on a 57 feet string at an angle

 of 68 with the ground

∴ FK = 57 feet

∴ m∠KFH = 68°

∵ We need to know that Helio is how far from the kite

∴ We need to calculate the length of KH

* Now lets find the best way to find the length of KH

 using the trigonometry

- We have the length of two sides and the measure of the included

 angle between them , then the best way is the cosine Rule

* Lets explain the cosine rule:

- In ΔABC:

∵ a is the length of the side opposite to ∠A ⇒ a is BC

∵ b is the length of the side opposite to ∠B ⇒ b is AC

∵ c is the length of the side opposite to ∠C ⇒ c = AB

∴ a² = b² + c² -2bc × cos(A)

∴ b² = a² + c² -2ac × cos(B)

∴ c² = a² + b² -2ab × cos(C)

* We will use the rule in our problem to find HK

∵ FH is k , HK is f , KF is h

∴ f² = h² + k² - 2hk × cos(F)

∵ h = 57 feet , k = 15 feet , m∠F = 68°

∴ f² = (57)² + (15)² - 2(57)(15) × cos(68) = 2833.4227

∴ f = √2833.4227 = 53.2 feet

* Helio is 53.2 feet from the kite
