Answer 1

Answer:

x = -5 + [tex]\sqrt{26}[/tex]

Step-by-step explanation:

f(x) = x² + 10x - 1

        x² + 10x = 1

        x² + 10x + 25 = 1 + 25

        (x + 5)² = 26

take the square root of each side to get:

        x + 5 = √26

        x = √26 - 5  or -5 + √26

Answer:

x = √53

Use the pythagorean theorem to solve for x, which would be c in the equation a^2 + b^2 = c^2.

(a and b are the sides that meet up in a right triangle, c is the hypotenuse. In this case, you are solving for the hypotenuse.)

Step-by-step explanation:

1. Plug in the numbers in the pythagorean theorem.

2^2 + 7^2 = c^2 (remember, each variable is squared)

2. Simplify.

4 + 49 = 53

Since each variable in the pythagorean theorem is squared, the side value would be √53.

Answers

Answer:

Simplified form of [tex]\frac{x+1}{x^2+x-6}\div \frac{x^2+5x+4}{x-2}[/tex] is [tex]\mathbf{\frac{1}{(x+3)(x+4)} }[/tex]

Option A is correct answer.

Step-by-step explanation:

We need to find simplified form of [tex]\frac{x+1}{x^2+x-6}\div \frac{x^2+5x+4}{x-2}[/tex]

Solving the given expression:

[tex]\frac{x+1}{x^2+x-6}\div \frac{x^2+5x+4}{x-2}[/tex]

First we find factors of [tex]x^2+x-6[/tex]

[tex]x^2+x-6 \\= x^2+3x-2x-6\\= x(x+3)-2(x+3)\\=(x-2)(x+3)[/tex]

So, factors of [tex]x^2+x-6[/tex] are [tex](x-2)(x+3)[/tex]

Now, fining the factors of [tex]x^2+5x+4[/tex]

[tex]x^2+5x+4\\=x^2+4x+x+4\\=x(x+4)+1(x+4)\\=(x+1)(x+4)[/tex]

So, factors of [tex]x^2+5x+4[/tex] are [tex](x+1)(x+4)\\[/tex]

Now the given expression will become:

[tex]\frac{x+1}{(x-2)(x+3)}\div \frac{(x+1)(x+4)}{x-2}[/tex]

Now, converting division sign into multiplication sign:

[tex]=\frac{x+1}{(x-2)(x+3)}\times \frac{x-2} {(x+1)(x+4)}\\Cancelling, \:common\:terms\\=\frac{1}{(x+3)(x+4)}[/tex]

So, simplified form of [tex]\frac{x+1}{x^2+x-6}\div \frac{x^2+5x+4}{x-2}[/tex] is [tex]\mathbf{\frac{1}{(x+3)(x+4)} }[/tex]

Two sides of a triangle measure 17 inches and 9 inches. Which cannot be the length of the remaining side?

Answers

Answer: B. 26

Step-by-step explanation:

The options are:

A. 21

B. 26

C. 9

D. 15

Let the third side of the triangle be x.

Since the two sides of a triangle measure 17 inches and 9 inches, therefore we can form a triangle inequality with the figures given. This would be:

x + 9 > 17

x > 17 - 9

x > 8

Also,

x < 9 + 17

x < 26

Therefore, 8 < x < 26

Therefore, the answer is 26.

Mark has a bag with different flavors of candy. The bag contains 4 cherry, 3 lemon, 7 watermelon, and 2 grape candies. Which of the following shows the complement of selecting a grape candy?

Answers

The complement of selecting a grape candy is D. 7:8.

What is the complement in probability?

The complement of a choice is the ratio of not choosing the specified item in preference to others.

The chance of choosing a grape candy is 1/8 or 1:8.  The complement of choosing a grape candy is 7:8 or (1 - 1/8).

The complement of a choice is the opposite probability of choosing an event.

Items          Number    Ratio

Cherry               4         4/16

Lemon               3         3/16

Watermelon      7         7/16

Grape candies  2        2/16

Total                 16

The ratio of grape candies = 2/16 or 1:8

The ratio of not choosing grape candies = 14/16 or 7/8

Thus, the likelihood of failing to choose a grape candy is Option D.
