The area of the figure is 254.8 m²

Area is the region occupied by an object.

Since the figure is a rectangle and containing two semi-circles, we find the area of the figure by finding the area of the rectangle and the two semi-circles.

The area of the rectangle is given by A = LW where

Given that

A = LW

= 16 m × 12 m

= 192 m²

The area of a semi-circle with diameter d is A = πd²/4

Now for the first semi-circle, its diameter d' = 8 m.

So, its area A' =  πd'²/4

=  π(8 m)²/4

= π64 m²/4

= 16π m²

= 16 ×3.14 m²

= 50.24 m²

Also, for the fsecond semi-circle, its diameter d" = 4 m.

So, its area A' =  πd'²/4

=  π(4 m)²/4

= π16 m²/4

= 4π m²

= 4 × 3.14 m²

= 12.56 m²

So, the area of the figure is A₁ = A + A' + A"

= 192 m² + 50.24 m² + 12.56 m²

= 254.8 m²

So, the area of the figure is 254.8 m²

The statement that correctly compares the two functions is

They have the same x-intercept and the same end behavior as x approaches ∞.

A function's final behaviour is represented by the value of f(x) as x approaches infinity. Both functions in this scenario have the same final behaviour because they both have unbounded growth, or they both go to positive infinity.

To find y-intercept of a function we have to put x= 0

So, The y-intercept of f(x) is y = -3.

and, The y-intercept of g(x) is y = -4.

To  find x -intercept of a function put y = 0

Answer:

Step-by-step explanation: A congruence statement expresses that two figures have the same size and shape. Here's how you can write a congruence statement step by step:

Write the two figures you want to compare. For example, you could write "Triangle ABC" and "Triangle DEF".

Use the symbol "≅" to indicate congruence. Place the symbol between the two figures, like this: "Triangle ABC ≅ Triangle DEF".

Label the corresponding parts of the two figures to show that they are congruent. For example, you could write "AB = DE", "BC = EF", and "AC = DF".

The final congruence statement would look like this: "Triangle ABC ≅ Triangle DEF, with AB = DE, BC = EF, and AC = DF". This statement says that Triangle ABC is congruent to Triangle DEF, and that the lengths of their corresponding sides are equal.

The equation of the given line is [tex]y= \frac{1}{3}x+2[/tex]

What is the slope of a line?

A line's steepness and direction are measured by the line's slope. Any two different points on a line can be used to calculate the slope of any line. The ratio of "vertical change" to "horizontal change" between two different locations on a line is calculated using the slope of a line formula.

Given a straight line in a graph, we need to find the equation of this line

from the graph, we can see that the line passes through the axes at (0, 2) and (-6, 0)

now, the slope of the line is [tex]\frac{y2 - y1}{x2 - x1}[/tex]

[tex]= \frac{0 - 2}{-6 - 0} \\= \frac{1}{3}[/tex]

The line makes an intercept of 2 on the Y-axis, as we can see clearly

The slope-intercept form of the line is y = mx + c, where 'c' is the intercept and 'm' is the slope of the line

The formula possible formula for the trigonometric function whose values are in the following table is  y = 6 x sin(π/2 * x) - 4.

Trigonometric functions are described as the periodic functions which denote the relationship between angle and sides of a right-angled triangle.

The formula for a trigonometric function is typically written as :

y = a sin (bx + c) + d

where a, b, c, and d are constants which tells us  the amplitude, frequency, phase shift, and vertical shift of the function, respectively.

From the above table,  the amplitude = 6,

The circumference of a circle with a diameter of 26 feet is approximately 81.64 feet.

What is the circumference?

The circumference is the length of any great circle, the intersection of the sphere with any plane passing through its center. A meridian is any great circle passing through a point designated as a pole.

The formula for the circumference of a circle is 2 * π * r, where r is the radius of the circle.

To find the circumference, we first need to find the radius of the circle.

The diameter of the circle is 26 feet, so the radius can be calculated by dividing the diameter by 2:

r = 26 feet / 2 = 13 feet

Now that we know the radius, we can find the circumference:

C = 2 * π * r = 2 * 3.14 * 13 = 81.64 feet

Therefore, the circumference of a circle with a diameter of 26 feet is approximately 81.64 feet.

Answer:

Step-by-step explanation:

o find the solution of a system of linear equations, we can find the point where the two lines intersect. The point of intersection represents the solution to the system of equations.

The first linear equation can be determined by finding its slope and y-intercept using the given points:

m = (7 - 6) / (3 - 1) = 1

b = 6 - m * 1 = 6 - 1 * 1 = 5

y = mx + b

y = x + 5

The second linear equation can be found similarly:

m = (8 - 6) / (5 - 3) = 1

b = 6 - m * 3 = 6 - 1 * 3 = 3

y = mx + b

y = x + 3

Since the two lines have the same slope, they are coincident and represent the same line. The solution to the system of equations is therefore any point on this line, but since we were asked for a specific point, we can choose (3,6) as the solution.

.

The statement is true. A confidence interval is a range of values that is likely to contain the true value of the parameter with a certain degree of confidence.

In this case, we are interested in the odds ratio between MI (yes, no) and treatment (placebo, aspirin).

If the 95% confidence interval for the odds ratio between MI and placebo is (1.44, 2.33), this means that we can be 95% confident that the true odds ratio falls between these two values. This implies that the odds of having an MI are between 1.44 and 2.33 times greater for those taking the placebo compared to those taking aspirin.

When we switch the rows so that aspirin is in the first row, we need to take the reciprocal of the upper and lower bounds of the confidence interval to get the new interval. This is because the odds ratio is calculated as the odds of MI for one group divided by the odds of MI for the other group, and switching the groups changes the ratio.

So, if we take the reciprocal of the lower and upper bounds of the original interval, we get:

1/2.33 and 1/1.44

which is the new 95% confidence interval for the odds ratio when aspirin is in the first row. Therefore, the statement is true.

Step-by-step explanation:

3/4 is 75%, and 1/4 is 25 percent. 3/4 is greater than 1/4!

The marked-up price of the discounted tablet computer is $298.35.

A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.

Given, During a sale, a store offered a 35% discount.

So, The discounted price of the computer tablet is,
