Answer:

the absolute maximum is 3 because it's the highest point on the graph

Step-by-step explanation:

The limit of the given function is 1/2

Given the following limit of a function

lim x→0 √(x²+4)-2/x²​

Substitute the limit to have:

√(0²+4)-2/0²​

√4 - 2/0

2-2/0

0/0 (ind)

Apply the L'hospital rule to have;

lim x→0 d/dx√(x²+4)-2/(d/dx)x²​

lim x→0 (x²+4)^-1/2 * 2x/2x

lim x→0 (x²+4x)^-1/2

Substitute

(4)^-1/2

1/2

Hence the limit of the given function is 1/2

Step-by-step explanation:

2(4+7a^2)

=8+14a^2

=7a^2+4

OR if that 2 is an exponent

(4+7a^2)^2

=(4+7a^2)(4+7a^2)

=16+49a^4+28a^2+28a^2

The answer is M = (C-5)/4

Answer:

6 foot

Step-by-step explanation:

Since the board is 12foot and the angle makes 60 degrees to the wall, we can assume that it is the 30,60,90 degreees. 30,60,90 degrees triangle makes the side of x, 2x ,and xroot3.

Hence, the board(12foot) is equal to 2x.

x=6

The triangle ABC drawing, which has vertices at A (1,6), B (1,1), and C (5,1) is shown below.

A triangle is the most basic form for a polygon with three sides and three vertices. Triangles are divided into various groups using their sides and angles. The triangle's total angle is always equal to 180 degrees, which is an interesting triangle fact (straight angle).

It is common knowledge that a triangle is a type of polygon with three edges and three vertices.

A, B, and C are frequently used to denote its vertices, making it one of the most important shapes in geometry.

A (1,6), B (1,1), and C (5,1) will be picked as the points. 〖〖AB〗^2+ 〖BC〗^2= AC〗^2

Hence, the image of the triangle ABC's design, which has vertices at A (1,6), B (1,1), and C (5,1) is linked above.

Dale should use the $15 dollars off coupon to save the most money which costs 47.00.

25% off of 47.00 is 45.49.

$15 off of 47.00 is 32.00.

The $15 off coupon makes the DVD player cost less, so he should use that one.

Answer:

(x + 7)² + (y - 1)² = 64

Step-by-step explanation:

Use the equation of a circle, (x - h)² + (y - k)² = r²

Plug in the point and center, then solve for r:

(x - h)² + (y - k)² = r²

(-7 + 7)² + (9 - 1)² = r²

0 + 64 = r²

64 = r²

8 = r

Then, plug in the center and r² into the equation:

(x + 7)² + (y - 1)² = 64

So, (x + 7)² + (y - 1)² = 64 is the standard form of the circle's equation

Answer:

B) x = 0

Step-by-step explanation:

To find the solution value that satisfies the inequality x – 6 ≥ –7, you must plug every x value into the x and see which one works.

Plug -5 into x

-5 – 6 ≥ –7

Combine like terms

-11 ≥ –7

This is false, -11 is not greater than or equal to -7.

Plug 0 into x

0 – 6 ≥ –7

Combine like terms

– 6 ≥ –7

This is true, -6 is greater than -7.

Plug -2 into x.

-2 – 6 ≥ –7

Combine like terms

-8 ≥ –7

This is false, -8 is not greater than or equal to -7.

Plug -7 into x.

-7 – 6 ≥ –7

Combine like terms

-13 ≥ –7

This is false, -13 is not greater than or equal to -7.

B) x = 0 is the only solution that is true and works, so that is your answer.

=================================================

Explanation:

Sort the values from smallest to largest.

You should get {22, 53, 60, 98, 102}

The middle most value is 60, so this is the median.

If you wanted, you can cross off the outermost pair of values (22 and 102) to end up with {53, 60, 98} to help see the middle better.

----------

Another approach:

We have n = 5 items in the sorted set {22, 53, 60, 98, 102}

The middle-most value is in slot 3 since n/2 = 5/2 = 2.5 which rounds up to 3. The value in slot 3 is 60, so this is the median. This trick only works when we have an odd number of values.

Answer: the median is 60

Step-by-step explanation: It is 60 because in order to find the mean you have to put all the numbers in order from least to greatest.

22,53,60,98,102.

after doing this you have to see how many quantity of data will pair up and the one that is left in the middle is the median. In other words you have 5 data sets in this example, 22 and 102 will be a pair and so will 53 and 98 which would leave 60 in the middle with no pair hence 60 would be the median

[tex]2ab^2-\frac{a^2b^2}{5}=\frac{10ab^2-a^2b^2}{5}[/tex]

Step-by-step explanation:

Given the expression

[tex]2ab^2-\frac{a^2b^2}{5}[/tex]

[tex]\mathrm{Convert\:element\:to\:fraction}:\quad \:2ab^2=\frac{2ab^25}{5}[/tex]

[tex]2ab^2-\frac{a^2b^2}{5}=\frac{2ab^2\cdot \:5}{5}-\frac{a^2b^2}{5}[/tex]

[tex]\mathrm{Since\:the\:denominators\:are\:equal,\:combine\:the\:fractions}:\quad \frac{a}{c}\pm \frac{b}{c}=\frac{a\pm \:b}{c}[/tex]

                 [tex]=\frac{2ab^2\cdot \:5-a^2b^2}{5}[/tex]

                 [tex]=\frac{10ab^2-a^2b^2}{5}[/tex]

Thus,

[tex]2ab^2-\frac{a^2b^2}{5}=\frac{10ab^2-a^2b^2}{5}[/tex]

Answer:

Percentage Gain = 12.5%

Step-by-step explanation:

Given

[tex]Cost\ Prize = 9.60[/tex] per dozen

[tex]Selling\ Price = 18[/tex] per 20

Required

Determine the percentage gain or loss

First, we have to calculate the unit cost price and the unit selling price.

If a dozen costs 9.60

Then 1 costs

[tex]Cost = 9.60/12[/tex]

[tex]Cost = 0.80[/tex]

If he sells 20 for 18

Then he sells 1 for:

[tex]Sell = 18/20[/tex]

[tex]Sell = 0.9[/tex]

The percentage change is then calculated as:

[tex]\%Change = \frac{Sell - Cost}{Cost} * 100\%[/tex]

[tex]\%Change = \frac{0.9 - 0.8}{0.8} * 100\%[/tex]

[tex]\%Change = \frac{0.1}{0.8} * 100\%[/tex]

[tex]\%Change = \frac{0.1 * 100\%}{0.8}[/tex]

[tex]\%Change = \frac{10\%}{0.8}[/tex]

[tex]\%Change = 12.5\%[/tex]

Because the percentage change is positive, then he made a gain.

Hence:

Percentage Gain = 12.5%
