A Number Of Squares Are Connected In A Row To Form A Rectangle. The Table Shows The Relationship Between

Answers

Answer 1

Answer:

✅The table can be represented by the equation, [tex] y = 4x + 4 [/tex]

✅The relation is a function.

✅The graph of the function is linear.

Step-by-step explanation:

✍️The first statement: The table can be represented by the equation, [tex] y = 4x + 4 [/tex].

To check if the first statement is correct let's find the equation that can represent the table by finding the slope (m) and y-intercept (b).

Using two pairs, (1, 8) and (2, 12),

Slope = [tex] \frac{y_2 - y_1}{x_2 - x_1} = \frac{12 - 8}{2 - 1} = \frac{4}{1} = 4 [/tex].

Substitute, x = 1, y = 8, and m = 4 into y = mx + b to solve for b.

Thus:

8 = (4)(1) + b

8 = 4 + b

Subtract 4 from each side

8 - 4 = b

4 = b

Plug in the values of b and m into y = mx + b.

Thus, the equation that represents the table would be:

[tex] y = 4x + 4 [/tex].

✅Therefore, the first statement is correct.

✍️The second statement: The graph of the function is non-linear.

This is NOT TRUE because the equation of the function, [tex] y = 4x + 4 [/tex], represents the equation of a linear graph in the slope-intercept form. When graphed, it will give us a straight line.

✍️The Third statement: The relation is a function.

This is TRUE because each input value (x-value) has exactly one output value (y-value).

✍️The Fourth statement: The rate of change is NOT constant.

This standby is NOT TRUE.

The rate of change is the slope (m) that we have calculated above to be 4. Between any two pairs, the rate of change remains 4.

Therefore, this statement is not correct.

✍️The Fifth statement: The graph of the function is linear.

This is TRUE. As stated earlier, from the equation generated, it is safe to say that the equation represents graph of a linear function. The graph will be a straight line graph.

Answer 2

The true statements are:

(a) The equation of the function is [tex]\mathbf{y = 4x +4}[/tex](c) The relation is a function(e) The graph is linear

(a) The equation of the function

Start by calculating the slope (m)

[tex]\mathbf{m = \frac{y_2 - y_1}{x_2 -x_1}}[/tex]

So, we have:

[tex]\mathbf{m = \frac{12 - 8}{2 -1}}[/tex]

[tex]\mathbf{m = 4}[/tex]

The equation is then calculated as:

[tex]\mathbf{y = m(x -x_1) + y_1}[/tex]

So, we have:

[tex]\mathbf{y = 4(x -1) + 8}[/tex]

[tex]\mathbf{y = 4x -4 + 8}[/tex]

[tex]\mathbf{y = 4x +4}[/tex]

Hence, this statement is true

(b) The graph is nonlinear

Because of (a) above, the graph is linear

Hence, this statement is false

(c) The relation is a function

A linear relation is a function

Hence, this statement is true

(d) The rate of change is not constant

Because of (a) above, the rate of change is constant

Hence, this statement is false

(e) The graph is linear

Because of (a) above, the graph is linear

Hence, this statement is true

Lets define a=1st number, b=2nd number, and c=3rd number

We know that a+b+c=126

We also know that the second number is 6 more than the first, so we can represent this as b=a+6

We also know that the third number is 3 times the first which can be represented as c=3a

We can plug these new values into our original equation and get:

a+(a+6)+(3a)=126

2a+6+3a=126 COMBINE LIKE TERMS

5a+6=126

5a=120

a=24

Our first number is 24.

Our second number is 6 more than our first number, so the second number is 24+6=30

Our third number is 3 times the first number, so the third number is 3(24)=72

We can check by plugging these numbers in for a, b, and c in our original equation

a+b+c=126

24+30=72=126

126=126

The numbers are 26, 20, and 80.

What is an expression?

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Three numbers:

First = a

Second = b

Third = c

Now,

a + b + c = 126 ____(1)

c = 4b ____(2)

b = a - 6 _____(3)

From (1), (2), and (3) we get,

a + (a - 6) + 4b = 126

a + a - 6 + 4b = 126

2a + 4b = 126 + 6

2a + 4b = 132

2a + 4(a - 6) = 132

2a + 4a - 24 = 132

6a = 132 + 24

6a = 156

a = 26

Now,

a = 26

b = a - 6 = 20

c = 4b = 4 x 20 = 80

Thus,

The numbers are 26, 20, and 80.

Given that sin x = 3/4
where x is an obtuse angle, find the exact value of cos x.

Answers

Answer:

Step-by-step explanation:

sin x =3/4

x is an obtuse angle and sin x is positive .

∴ x lies in 2nd quadrant.

Hence cos x is negative.

[tex]cos x=-\sqrt{1-sin^2x} =-\sqrt{1-(3/4)^2} =-\sqrt{1-\frac{9}{16} } =-\sqrt{\frac{7}{16} } =-\frac{\sqrt{7} }{4}[/tex]

Solving a trigonometric equation, it is found that:

[tex]\cos{x} = -\frac{\sqrt{7}}{4}[/tex]

The sine and the cosine of an angle x are related by the following equation:

[tex]\sin^2{x} + \cos^2{x} = 1[/tex]

In this problem:

x is an obtuse angle, which means that it is the second quadrant, in which the sine is positive and the cosine is negative.

[tex]\sin{x} = \frac{3}{4}[/tex], thus:

[tex]\sin^2{x} + \cos^2{x} = 1[/tex]

[tex](\frac{3}{4})^2 + \cos^2{x} = 1[/tex]

[tex]\frac{9}{16} + \cos^2{x} = 1[/tex]

[tex]\cos^2{x} = 1 - \frac{9}{16}[/tex]

[tex]\cos^2{x} = \frac{7}{16}[/tex]

[tex]\cos{x} = \pm \sqrt{\frac{7}{16}}[/tex]

Since the cosine is negative.

[tex]\cos{x} = -\frac{\sqrt{7}}{4}[/tex]

What is 48,020,000 expressed in scientific notation?

C. 0.4802 x 10^8
D. 4.802 x 10^8

Answers

A is the correct answer

Answer:

im pretty sure it is answer A. 4.802 x 10^7

Step-by-Step explanation

The purpose of scientific notation is for scientists to write very large, or very small, numbers with ease.

Calculating scientific notation for a positive integer is simple, as it always follows this notation:

a x 10b

Follow the steps below to see how 48,020,000 is written in scientific notation.

Step 1

To find a, take the number and move a decimal place to the right one position.

Original Number: 48,020,000

New Number: 4.8020000

Step 2

Now, to find b, count how many places to the right of the decimal.

New Number: 4 . 8 0 2 0 0 0 0

Decimal Count:   1 2 3 4 5 6 7

There are 7 places to the right of the decimal place.

Step 3

Building upon what we know above, we can now reconstruct the number into scientific notation.

Remember, the notation is: a x 10b

a = 4.802 (Please notice any zeroes on the end have been removed)

b = 7

Now the whole thing:

4.802 x 107

Step 4

Check your work:

107 = 10,000,000 x 4.802 = 48,020,000
