Find the area of the triangle.

Answer:

153.86 in²

Step-by-step explanation:

Area of circle = \(\pi r^2\)

d = 14 inches, r = d/2 = 7 inches

= 3.14 * 7 * 7

= 153.86 in²

multiply all the numbers with -7 and make a new matrix

In 24-hour clock time the clock shows a. 10:32

We need the basics of converting am/pm system to a 24-hour time. In the 24-hour system, the clock doesn't use am/pm symbol and when the clock shows pm we need to add 12 hours before, for example:

am

01:00 am = 01:00

we don't need to add 12 hours before and erase the am symbol.

pm

01:00 pm = 13:00

we need to add 12 hours before (01 + 12 = 13)

Hence, when the clock shows 10:32 am, we don't need to add 12 hours before and just erase the am symbol. The 24-hour time will be at 10:32.

Answer:

45 degrees

Step-by-step explanation:

Because the shape is a square, all of the sides are equal and all of the angles are 90 degrees. From there you simply divide  90 by 2.

Answer:

∠ ABE = 45°

Step-by-step explanation:

The diagonals of a square bisect the angles, thus

∠ ABC = 90°, so

∠ ABE = 0.5 × 90° = 45°

Using the distributive property, the expanded form of (−1/4)(−8x+12y) is c) 2x - 3y.

The distributive property states that when you multiply a number or a variable expression by a sum or a difference, you can distribute the multiplication over each term within the parentheses.

So, to expand the expression (−1/4)(−8x+12y), we can apply the distributive property by multiplying -1/4 to each term inside the parentheses:

(−1/4)(−8x+12y) = (−1/4) × (−8x) + (−1/4) × (12y)

= (1/4) × 8x − (1/3) × 12y

= 2x − 3y

Therefore, the expanded form of (−1/4)(−8x+12y) is 2x − 3y. Hence, the correct answer is (c) 2x-3y.

This pooled estimate provides a common probability of success for both populations under the null hypothesis H0: p1 = p2, and is used in the calculation of the test statistic for the hypothesis test.

To calculate the best pooled estimate p for the population probability of success using H0: p1 = p2, we first need to calculate the individual sample proportions for each population.

The sample proportion for the first population is r1/n1, and the sample proportion for the second population is r2/n2.

Then, we can calculate the pooled estimate p as:

p = (r1 + r2) / (n1 + n2)

This is the weighted average of the sample proportions, where the weight is proportional to the sample size.

Using this pooled estimate p, we can then calculate the test statistic for the hypothesis test of difference of proportions.

two-variable linear equations in the standard form Class 9

Hence, a linear equation with two variables is any equation that can be written in the form axe + by + c = 0, where a, b, and c are real values, and a and b are not equal to zero. This implies that you can come up with a tonne of these equations.

For the question:

Let the age of the daughter be 'x'.

Let the age of the father be 'y'.

After 3 years:

10(x + 3) = (y + 3)

10x + 30 = y  + 3

y = 10x + 27  ..eq 1

One year ago

(x - 1) +  (y - 1) = 36

Answer:

a

Step-by-step explanation:

These are basic properties of parallelograms and there's really no way to explain other than memorizing them.

Answer:

This equation does not have the same solution as the original equation.

In conclusion, equations 1 and 2 have the same solution as the original equation (2.3p – 10.1 = 6.5p – 4 – 0.01p). Equations 3, 4, and 5 do not have the same solution.

Step-by-step explanation:

2.3p – 10.1 = 6.4p – 4

Using the commutative property of addition, we can rearrange the terms on the left-hand side of the equation to get:

-6.4p + 2.3p = -4 + 10.1

Combining like terms, we have:

-4.1p = 6.1

Dividing both sides by -4.1, we get:

p = -1.49

This equation has the same solution as the original equation.

2.3p – 10.1 = 6.49p – 4

Using the commutative property of addition, we can rearrange the terms on the left-hand side of the equation to get:

-6.49p + 2.3p = -4 + 10.1

Combining like terms, we have:

-4.19p = 6.1

Dividing both sides by -4.19, we get:

p = -1.46

This equation has the same solution as the original equation.

230p – 1010 = 650p – 400 – p

This equation does not have the same solution as the original equation.

23p – 101 = 65p – 40 – p

This equation does not have the same solution as the original equation.

2.3p – 14.1 = 6.4p – 4

Using the commutative property of addition, we can rearrange the terms on the left-hand side of the equation to get:

-6.4p + 2.3p = -4 + 14.1

Combining like terms, we have:

-4.1p = 10.1

Dividing both sides by -4.1, we get:

p = -2.47

C) g(x) = f(x) + 4

Step-by-step explanation:

A vertical shift is where you shift, slide or translate the whole graph up or down (on a graph) The way this shows up in the equation is just a number tacked on to the end of the equation. A +anumber (like the +4 in the answer) slides the function UP four units. A

-anumber would slide the function DOWN instead.

As for the other answers:

A) the 3multiplied in front is a vertical STRETCH.

D) the 1/2 multiplied in front is a vertical shrink (smash)

B) The -3 in close tight with the x is a horizontal shift(slide, translate) It is a RIGHT shift. A +anumber would be a LEFT shift. Horizontal shift seem kind of backwards. + goes LEFT and - goes RIGHT.

The function represented by the f(x) =\(2(\frac{1}{2})^x\) is an exponential decay function

The function is  

f(x) =\(2(\frac{1}{2})^x\)

The function is defined as the expression that represents the relationship between one variable and another variable.

The function is in the form of

f(x) = a × \(b^x\)

Such functions are called exponential function

Here  

The value of a = 2

The value of b = 1/2

If the value of b > 1, the function is called exponential growth function.

If the value of b < 1, the function is called exponential decay function.

Here b < 1

Therefore it is exponential decay function

Hence, the function represented by the f(x) =\(2(\frac{1}{2})^x\) is an exponential decay function

Descriptive statistics are used to summarize data in a useful and informative manner.

This type of statistics provides meaningful information about the data set by organizing and presenting it in an easily understandable format. Descriptive statistics can be used to summarize the data in the form of tables, graphs, and charts. It can also be used to provide detailed information about the data set, such as the mean, median, mode, standard deviation, and range.

Descriptive statistics can also be used to make inferences about a population. This is done by comparing the data collected from a sample to the characteristics of the population. By understanding the characteristics of the population, researchers can make accurate predictions about the behavior of the population.

Descriptive statistics can also be used to determine if the data adequately represent the population. This involves analyzing the sample size, data accuracy, and the assumptions made about the population. If the data does not accurately represent the population, then researchers have to make changes to their data collection process or revise their assumptions about the population.

Finally, descriptive statistics can be used to gather or collect data. This involves designing surveys, experiments, and other data collection methods. By using descriptive statistics to collect data, researchers can ensure that the data is valid and reliable.

After divide, the solution of the expression is,

⇒ x (x + 2y) / 5

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that;

The expression is,

⇒ (x² - 4y²) ÷ (5x - 10y) / x

Now, We an simplify as;

⇒ (x² - 4y²) ÷ (5x - 10y) / x

⇒ (x² - (2y)²) ÷ (5x - 10y) / x

⇒ (x - 2y) (x + 2y) ÷ 5(x - 2y) / x

⇒ (x - 2y) (x + 2y) × x/ 5 (x - 2y)

⇒ x (x + 2y) / 5

Step-by-step explanation:

Y-intercepts and x-intercepts are points on the graph that are on the y-axis and x-axis, respectively.

Looking at the graph, the graph passes through the y-axis at y=2. Therefore, the y-intercept is 2.

Looking at the graph, the graph passes through the x-axis at x=-2 and x=4. Therefore, the x-intercepts are -2 and 4.

Rounding to the nearest whole number, she will have run a total distance of 13 kilometers after 16 days.

To find out how far she will have run in total after 16 days, we can use the formula for calculating compound interest:

A = P(1 + r/100)^n

Where:

A = Total distance run after n days

P = Initial distance (4.8 kilometers)

r = Rate of increase per day (6.9%)

n = Number of days (16)

Plugging in the given values, we can calculate the total distance:

A = 4.8(1 + 6.9/100)^16

Using a calculator or performing the calculations step by step, we get:

A ≈ 4.8(1.069)^16 ≈ 4.8(2.092473)^16 ≈ 4.8(2.628)

A ≈ 12.6144
