Evaluate: 6.2x - 3y where x=2 and y=3
please help me I don't understand

Answers

Answer 1

Answer:

3.4

Step-by-step explanation:

6.2(2) - 3(3)

12.4 - 9

3.4

:)

Answer 2

Answer:

3.4

Step-by-step explanation:

6.2x = 6.2 x 2 = 12.4

y = 3

3y = 3 x 3 = 9

Hence, it is 12.4 - 9 = 3.4

Additional notes: If there is a integer/number bigger than 1 at the start of the alphabet, for example find 4y when y = 4 it's just basically multiplying the number which represents the alphabet with the value at the back of the alphabet. For example, to find 4y it is supposed to be 4 x 4 = 16.

Find an equation of the tangent line to the curve at the given point. y=√x, (49,7) To find the equation of a line, we need the slope of the line and a

Answers

Answer:

The equation of the tangent line to the curve at the given point is [tex]y = \frac{1}{14}(x - 49) + 7[/tex]

Step-by-step explanation:

Equation of the tangent line:

The equation of the tangent line to a function f(x) at a point [tex](x_0,y_0)[/tex] is given by:

[tex]y - y_0 = m(x - x_0)[/tex]

In which m is the slope, which is given by the derivative of f(x) at [tex]x_{0}[/tex]

y=√x, (49,7)

This means that [tex]x_0 = 49, y_0 = 7[/tex]

The derivative is:

[tex]y^{\prime} = \frac{1}{2\sqrt{x}}[/tex]

At [tex]x = 49[/tex]

[tex]m = y^{\prime} = \frac{1}{2\sqrt{49}} = \frac{1}{14}[/tex]

So

[tex]y - y_0 = m(x - x_0)[/tex]

[tex]y - 7 = \frac{1}{14}(x - 49)[/tex]

[tex]y = \frac{1}{14}(x - 49) + 7[/tex]

The equation of the tangent line to the curve at the given point is [tex]y = \frac{1}{14}(x - 49) + 7[/tex]

Answers

The median of the two data sets compares as they will be the same.

How is the median illustrated?

The medians are the same because the median is the value such that 50% of the data points are higher and 50% are lower. Therefore, the actual value of the highest element doesn't affect the median.

The mean of set B is greater and the standard deviation of B is higher because the highest element is further from the mean. Also, the boxes are the same if the center line is the median since the interquartile range is the same.

(b) Find the approximate area of the sidewalk. Use 3.14 to approximate π.

Answers

Let R be the greater radius and r be the smaller radius

A) Area of the sidewalk = R^2 - r^2 - This can be the expression

B) = 3.14

A measurement of 4.5 yards is how many feet longer than a measurement of 132 inches?

Answers

Answer:

4.5X3=13.5, 132/12=11, 13.5-11=2.5

Step-by-step explanation:

A measurement of 4.5 yards is 2.5 feet longer than a measurement of 132 inches.

As we know that,

                  [tex]1 yard = 3 feet[/tex]

So,             4.5 yards = [tex]3*4.5=13.5feet[/tex]

               [tex]12 inch = 1 feet\\\\132inch = \frac{`132}{12}=11feet[/tex]

Difference between 4.5 yards and 132 inches = [tex]13.5-11=2.5feet[/tex]

Thus, the measurement of 4.5 yards is 2.5 feet longer than a measurement of 132 inches.

this is the answer step by step hope it helps

Answer:

The width of the rectangle is 15 inches.

Step-by-step explanation:

Take I as the length of the rectangle and w as its width. Use the relationship between the length and the width and express the length in terms of the width.

[tex]l = 1.5w[/tex]

The perimeter of a shape is the sum of its sidelength, use this imformation to write a expression for the perimeter of the rectangle;

[tex]p = 2l \: + 2w[/tex]

Now, replace l for the expression in terms of the width and P for the given perimeter, then solve for w:

[tex]75 = 2(1.5w) + 2w \\ 75 = 3 w + 2w \\ 75 = 5w \\ \frac{75}{5} = w \\ w = 15[/tex]

The width of the rectangle is 15 inches.
