Answer:

ok I did it two ways and got different answers

Step-by-step explanation:

addition

42^2 +69^2= x^2

1,764 +4,761=x^2

1,764 + 4,761= 6,525

Square root of 6,525 is 80.77 or 15/29

subtracting

4,761 -1,764= 2,997

Square root of 2,997 is 54.74 or 9/37

hope one of these are right, good luck

Answer:

The range of f(x) is:

[tex]y\in\{-1,0,1\}[/tex]

Step-by-step explanation:

Domain and Range

Given a function y=f(x), the domain of f(x) is the set of values that x can take and the range of f(x) is the set of values that f gets when x is in the domain.

We have the function:

[tex]\displaystyle f(x) = \frac{1}{2} x-2[/tex]

And the domain is

[tex]x\in\{2,4,6\}[/tex]

Compute the range by assigning each value of x:

For x=2:

[tex]\displaystyle f(2) = \frac{1}{2} \cdot 2-2=1-2=-1[/tex]

[tex]\displaystyle f(2) = -1[/tex]

For x=4:

[tex]\displaystyle f(4) = \frac{1}{2} \cdot 4-2=2-2=0[/tex]

[tex]\displaystyle f(4) = 0[/tex]

For x=6:

[tex]\displaystyle f(6) = \frac{1}{2} \cdot 6-2=3-2=1[/tex]

[tex]\displaystyle f(6) = 1[/tex]

The range of f(x) is:

[tex]y\in\{-1,0,1\}[/tex]

Answer:

B

The equation that represents the function g(x) is [tex]g(x)=9cos(x-\frac{\pi }{3} )+7[/tex].

Function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

Translation means the displacement of a figure or a shape from one place to another. In translation, a figure can move upward, downward, right, left or anywhere in the coordinate system. In translation, only the position of the object changes, its size remains the same.

The function is given as

[tex]f(x)=9cos(x-\frac{\pi }{2} )+3[/tex]

The function f(x) is first translated [tex]\frac{\pi }{6}[/tex] units left.

The rule of translation is:

[tex](x,y)=(x+\frac{\pi }{6},y)[/tex]

So, we have:

[tex]f'(x)=9cos(x+\frac{\pi }{6} -\frac{\pi }{2} )+3[/tex]

Take LCM

[tex]f'(x)=9cos(x+\frac{\pi-3\pi }{6} )+3[/tex]

[tex]f'(x)=9cos(x-\frac{2\pi }{6} )+3[/tex]

[tex]f'(x)=9cos(x-\frac{\pi }{3} )+3[/tex]

Next, translate f'(x) 4 units up.

The rule of this translation is:

[tex](x,y)=(x,y+4)[/tex]

So, we have:

[tex]g(x)=9cos(x-\frac{\pi }{3} )+3+4[/tex]

[tex]g(x)=9cos(x-\frac{\pi }{3} )+7[/tex]

Hence, the equation that represents the function g(x) is [tex]g(x)=9cos(x-\frac{\pi }{3} )+7[/tex].

Answer:

d = 10 inches

Step-by-step explanation:

It is given that,

The length, breadth and the height of a rectangular box is 8 inches×10 inches ×6 inches

We need to find the length of its longest diagonal.

In a rectangle, 6 inches will act as perpendicular and 8 inches will be base. The diagonal can be calculated using Pythagoras theorem as follows :

[tex]d=\sqrt{8^2+6^2} \\\\=\sqrt{64+36}\\\\=10\ \text{inches}[/tex]

So, the length of its diagonal is 10 inches.

Step-by-step explanation:

Answer:

54

Step-by-step explanation:

First let's replace the values x and y.

4y + 2x + 30 will become (4 * 5) + (2 * 2) + 30

Then we do order of operations.

(4 * 5) is 20..

20 + (2 * 2) + 30

Then we do (2 * 2) which is just four.

20 + 4 + 30

Lastly we add it all up.

24 + 30 = 54

Multiplication is a mathematical arithmetic operation.

The process of adding the same number many times is repeated addition.

Multiplication is a repeated addition.

Example - 2 × 3 means 2 is added three times, or 3 is added 2 times.

Given:

Last year,

a company that makes apple juice produced 8.3 billion bottles of apple juice.

And 355 milliliters of juice occupied by each bottle.

then the company produced,

The addition of the functions f(x) and g(x) will be (f+ g)(x) = x² – 2x – 13. Then the correct option is A.

Functions are found all across mathematics and are required for the creation of complex relationships.

If f(x) = 2x – 5 and g(x) = x² – 4x – 8.

Then the function (f+ g)(x) will be

(f+ g)(x) = f(x) + g(x)

(f+ g)(x) = 2x – 5 + x² – 4x – 8

(f+ g)(x) = x² – 2x – 13

Then the correct option is A.

Step-by-step explanation:

To calculate the slope, you can use the slope formula which is the change in the height compared to the change in the width. Using ordered pairs, this is the change in the y-values divided by the change in the x-values or the rise divided by the run.

Answer: She got 30 questions right and 6 questions wrong.

Step-by-step explanation:

Let x = Number of correct questions, y = Number of wrong questions

As Award for each correct answer = +3 points and Award for each wrong answer = -1 point.

Total score = 3x-1y

If Marjorie omitted 4 of the 40 questions, then she did 40-4=36 questions.

Now, x+y = 36 (1)

and 3x-y =84   (2)  (as she scored 84)

Adding (1) and (2), we get

4x = 120

Divide both sides by 4, we get

x= 30

y = 36-30=6

hence, she got 30 questions right and 6 questions wrong.

Answer:

Option (D)

Step-by-step explanation:

From the figure attached,

Since, ΔABD and ΔECD are the similar triangles,

Their corresponding sides will be proportional.

[tex]\frac{AB}{EC}=\frac{BD}{CD}[/tex]

[tex]\frac{h}{6}=\frac{(x+10)}{10}[/tex]

10h = 6(x + 10)

Since, the person is standing 35 feet from a street light,

x = 35 feet

By substituting the value of x in the equation,

10h = 6(35 + 10)

10h = 270

h = 27 ft

Therefore, height of the street light will be 27 feet.

Option (D) is the answer.

Answer:

There are 33 girls in choir

Step-by-step explanation:

4 x 11 = 44 (we get four from the 1 boy for every 4 girls)

assuming that we have 44 kids in the class, 1/4 will be boys. 44/4 = 11 which means that we subtract 11 from 44 which will get you 33.

If there is a total of 11 boys. Then the number of girls in the choir will be 44 girls.

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

PEMDAS rule means the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.

In the school, there is 1 boy for every 4 girls.

If there is a total of 11 boys. Then the number of girls in the choir will be given as,

⇒ 11 x 4

⇒ 44 girls

If there is a total of 11 boys. Then the number of girls in the choir will be 44 girls.
