Write a function max that has two c string parameters and returns the larger of the two.

Answers

char max(char number1, char *number2){
if (strcmp(number1, number2) > 0)
return number1;
else
return number2;
}

Final answer:

To determine the larger of two C strings, a function named max uses strcmp to compare them, returning the one considered greater in alphabetical order.

Explanation:

To write a function named max that returns the larger of two C strings, one must compare the two strings alphabetically. Here is an example implementation in C:

#include // Include the header file for string functions

// Function declaration
const char* max(const char* str1, const char* str2) {
// Compare the two strings
int result = strcmp(str1, str2);

// If str1 is greater than or equal to str2
if(result >= 0)
return str1;
else
return str2;
}

The strcmp function from the string.h library is used to perform the comparison. If the first string (str1) is greater than or equal to the second string (str2), str1 is returned; otherwise, str2 is returned. Note that the comparison is based on the ASCII values of the characters, effectively ordering them alphabetically.

A swimming pool is 15 by 30 feet and a consistent 5 feet deep. you are painting the walls and floor of the pool. if a gallon can of paint covers 250 square feet, how many gallon cans would you need to buy

Answers

the bottom of the pool is 15 x 30 = 450 sq feet.

you the have 2 walls that are 30 x 5 = 150 x 2 = 300 square feet

then 2 walls that are 15 x 5 = 75 x 2 = 150 square feet

for a total of 450 +300 +150 = 900 square feet

1 can covers 250 sq ft

so 900/250 = 3.6

so you would need 4 cans of paint

Each input can only have one output. The other tables have multiple outputs for each input. Therefore they get "cut off," and table D is the answer.

Help please. Find the value of the variable. If your answer is not an integer, leave it in simplest radical form.

A.5√2 /2

B.5√3

C.5√2

D.5√3 /2

Answers

Answer: The value of the variable is [tex]x=\dfrac{5\sqrt2}{2}.[/tex]

Step-by-step explanation: We are given to find the value of the variable 'x' in the figure.

We can see that the figure is a right-angled triangle with the length of the hypotenuse as follows:

h = 5 units.

Now, with respect to the angle of measure 45°, the length of the perpendicular is x units.

That is, p = x units.

From relations between trigonometric ratios, we have

[tex]\sin 45^\circ=\dfrac{\textup{perpendicular}}{\textup{hypotenuse}}\\\\\\\Rightarrow \dfrac{1}{\sqrt2}=\dfrac{p}{h}\\\\\\\Rightarrow \dfrac{1}{\sqrt2}=\dfrac{x}{5}\\\\\\\Rightarrow x=\dfrac{5}{\sqrt2}\\\\\\\Rightarrow x=\dfrac{5\sqrt2}{(\sqrt2)^2}\\\\\\\Rightarrow x=\dfrac{5\sqrt2}{2}.[/tex]

Thus, the value of the variable is [tex]x=\dfrac{5\sqrt2}{2}.[/tex]

find the center of the circle that can be circumscribed about triangle EFG, E(6,4) F(6,2) and G(10,2)

Answers

Final answer:

The center of the circumscribed circle about triangle EFG with given vertices is found by calculating the perpendicular bisectors of the triangle's sides and locating their intersection point, which is the center (8,3).

Explanation:

To find the center of the circumscribed circle about triangle EFG with vertices E(6,4), F(6,2), and G(10,2), we need to determine the perpendicular bisectors of at least two sides of the triangle and then find their intersection point, which will be the center of the circumscribed circle.

First, find the midpoint of side EF, which has the same x-coordinate (since E and F have the same x-coordinate), so the midpoint is (6,3).Next, we need the equation of the perpendicular bisector of EF. Since EF is vertical, its perpendicular bisector is a horizontal line that passes through the midpoint, hence the equation is y = 3.Then, find the midpoint of side FG. As the endpoints have the same y-coordinate, the midpoint will have that y-coordinate (2) and the x-coordinate will be the average of the x-coordinates of F and G, which is (6+10)/2 = 8. So, the midpoint of FG is (8,2).The slope of side FG is 0 (since it's horizontal), so the slope of its perpendicular bisector is undefined, meaning it's a vertical line. Consequently, the equation of this perpendicular bisector is x = 8.Last, by solving the system of equations formed by the two perpendicular bisectors x = 8 and y = 3, we find the intersection point, which is the center of the circumscribed circle: (8,3).

A mosaic is made by having 1 cm square tiles glued onto a photograph. the photograph is a 6 cm by 8 cm rectangular photo. It is enlarged by a scale factor of 1.5. how many tiles are needed to cover the enlarged photo

Answers

A scale factor is the ratio of two similar geometric figures of their corresponding sides. The scale factor is calculated by locating the corresponding sides on each figure. Enlargement of a figure would have a scale factor that is greater than 1 which is evident for the problem above. To determine how many tiles would be needed to cover the enlarged photo, we need to know the new dimension of the photo. We do as follows:

Old photo = 6 cm x 8 cm
New photo = 6 cm x 1.5 x 8 cm x 1.5
= 9 cm x 12 cm

Number of tiles = Area of photo / Area of tiles
Area of photo = 9 x 12 = 108 cm^2
Area of tiles = 1 cm x 1 cm = 1 cm^2

Number of tiles = 108 cm^2 / 1 cm^2 = 108 tiles

C. The circle is congruent to the hexagon.
D. Each vertex of the hexagon lies outside the circle.
E. The circle is tangent to each side of the hexagon.

Answers

A. The hexagon is circumscribed about the circle .
D. Each vertex of the hexagon lies outside the circle .
E. The circle is tangent to each side of the hexagon .

Answer: A. The hexagon is circumscribed about the circle.

D. Each vertex of the hexagon lies outside the circle.

E. The circle is tangent to each side of the hexagon.

Step-by-step explanation:

Given: A circle is inscribed in a hexagon.

Then the hexagon is circumscribed about the circle.

Each vertex of hexagon lies outside the circle.

As each side of hexagon is just attached to the circle not passing through the circle, thus the circle is tangent to each side of the hexagon.

Since circle is a closed curve and hexagon is regular polygon with 6 sides, they cannot be congruent because they have different shapes.

The record ski jump for women is 110 meters. What is this length in feet?

Answers

110 meters converted to feet is: 360ft

Answer:

The record ski jump for women is 360.89 feet.

Step-by-step explanation:

The record ski jump for women is 110 meters.

Record ski jump = 110 m

We need to find what is this length in feet.

We have the conversion 1 m = 3.28084 ft

Using the above conversion

We will get

1 m = 3.28084 ft

110 m = 110 x 3.28084 = 360.89 ft

The record ski jump for women is 360.89 feet.

A student claims that a figure has rotational symmetry and that the angle of rotational symmetry is 360 degrees. Critique the student's statement.

Answers

Remember rotational symmetry means if you turn it you end up with the same figure you started with. This happens with regular polygons since each angle is congruent. To find the angle of rotation you divide 360 by the number of angles. So if you rotated 360 degrees, that means 360/360=1. Your figure only had one angle, so it can't even be a polynomial! Also, every figure in the world will look exactly like it started if rotated 360 degrees, so this would not be logical.

The altitude to the hypotenuse of a right triangle divides the hypotenuse into two segments measuring 11 centimeters and 5 centimeters. to the nearest tenth, what is the length of the shorter leg of the triangle?

Answers

a^2 = x^2 - 5^2 where a = altitude, x=shorter leg and y=longer leg.

a^2 = y^2 + 11^2

x^2 - 5^2 = y^2 - 11^2.......... (1)

Also consider the whole triangle:

x^2 + y^2 = 16^2..........(2)

x^2 - y^2 = -96 .........(3) (from equation (1))

adding 2 x^2 = 256 + -96 = 160

x^2 = 80

x = sqrt80

What is the slope of a line that is perpendicular to the line v= 3/4x-6?

A. 3/4
B. -4/3
C. -3/4
D. 1/6

Answers

A perpendicular slope is equal to the negative reciprocal of the given slope, which is 3/4.

The reciprocal of 3/4 is 4/3. The negative of that is -4/3.

Final answer: B

The slope of line which is given to be perpendicular to the line represented by equation "v = (3/4)x - 6" is : (b) -4/3.

To determine the slope of a line that is perpendicular to the given line v = (3/4)x - 6, we use the property that perpendicular lines have slopes that are "negative-reciprocals" of each other.

The slope of the given line is 3/4. To find the slope of the perpendicular line, we take the negative reciprocal of 3/4.

The negative reciprocal of 3/4 is -4/3. So, the slope of the line that is perpendicular to the given-line v = (3/4)x - 6 is -4/3.

Therefore, the correct answer is (b) -4/3.

find the value of x.

Answers

To find the value of X, simply know that for this parallelogram, the angles on each end that are diagonal with respect to each other are the same. And knowing that the angles in a parallelogram add up to equal 360 degrees. Simply make an algebraic expression equal to the value of 360 and then solve for x.

X + X + (X - 26) + (X - 26) = 360
2X + X - 26 + X - 26 = 360
4X - 52 = 360
4x = 412
X = 103.

The value for X, I believe would be 103 degrees. You can verify this by plugging in the value into both expressions, X and X-26 and see that if adding all the expressions together does it equal 360 degrees.

15,000 loses value by 20% each year. What is the value after 3 years

Answers

So you have 15,000, which decreases in value by 20% each year. The question asks, what is the value after 3 years. So you would have 15,000(1-0.2)^3 and that is your equation. The reason for this is because you have your initial value 15,000, and when it is a percent decrease, you use the formula i(1-d)^x, where i represents the initial value, d represents the percent decrease, and x represents the number of years. We can convert 20% into a decimal as 0.2. So our initial value is 15000, our percent decrease is 0.2, and number of years we can see is 3. That is why the equation is 15,000(1-0.2)^3. I would solve this using PEMDAS, meaning that Parenthesis comes first, Exponents come second, and then Multiplication comes after both of those. I stopped here because these are the only three things we need to do to solve. When I solve this, I do (1-0.2) = 0.8, and (0.8)^3 = 0.512. Then I multiply 15,000 with 0.512, which gives me 7680. Therefore the value of 15000 after 3 years is $7680. Hope this helps. Feel free to ask me questions about my explanation, and feel free to post more questions.

Answer:

Step-by-step explanation: 7680

After losing 20% we have 80% remaining

∴ value after three years = 15,000 × [tex]\frac{80}{100}[/tex] × [tex]\frac{80}{100}[/tex] ×[tex]\frac{80}{100}[/tex]
