I rlly need help thanks the question is in the picture

Im a 5th grader and I don't even know that.

Answer:

1.363

Step-by-step explanation:

Area of the sector is x/360 * pi * r^2

A = 40/360 * pi * 7*7

= 1/9 * 22/7 * 49

= 1/9 * 22 * 7

= 17.111111

Area of the triangle OMN = 1/2 ab sin C

so here A = 1/2 * 7 * 7 * sin 40

= 49/2 * sin 40

= 15.748296437320213494904763542728

so, Area of shaded segment is

= Area of sector - area of triangle

= 17.1111111 - 15.748296437320213494904763542728

= 1.363

Answer:

Step-by-step explanation:

Simplifying

x2 + -9 = 0

Reorder the terms:

-9 + x2 = 0

Solving

-9 + x2 = 0

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '9' to each side of the equation.

-9 + 9 + x2 = 0 + 9

Combine like terms: -9 + 9 = 0

0 + x2 = 0 + 9

x2 = 0 + 9

Combine like terms: 0 + 9 = 9

x2 = 9

Simplifying

x2 = 9

Take the square root of each side:

x = {-3, 3}

Answer:

10^2=0

Step-by-step explanation

Because x by it self always means one it would technically be 1^2+9 which would equal 10^2=0

Answer:

325+250= 575

Step-by-step explanation:

If they want to make a profit of $1,725 or more, then they need to sell at least 101 tickets.

We know that each ticket costs $25, then if they sell t tickets the revenue is:

R(t) = 25t

We know that the band has a cost of $800, and they want to make a profit of at least $1,725, then we can write the inequality below:

25t - 800 ≥ 1,725

(remember that the profit is the difference between the revenue and the cost).

Now we can solve that for t.

25t  ≥ 1,725 + 800

25t  ≥ 2,525

t  ≥ 2,525/25

t  ≥ 101

They need to sell at least 101 tickets.

Answer:

77.5 degrees

Step-by-step explanation:

sin(90)/42=sin(?)/41

sin(90)/42 times 41=0.9761904

sin^-1(0.9761904)=77.47209456 degrees

The closest answer choice to this value is option 1, 33. Therefore, the best estimate for the unicity distance for an affine cipher is 33.

To find the best estimate for the unicity distance for an affine cipher, we can use the following formula:

Unicity Distance  (U) = (keyspace / entropy) × log2(1 / redundancy).

Given the answer choices:
1. 33
2. 35
3. 33
4. 26
5. 17.5

For an affine cipher, the keyspace is 26^2 (since there are 26 possibilities for both 'a' and 'b' in the equation

y = (ax + b) mod 26).

The entropy of English text is roughly 1.5 bits/character, and the redundancy is approximately 0.7.

Using the formula, we have:

U = (26^2 / 1.5) × log2(1 / 0.7)

U ≈ 33.49

Therefore, the best estimate for the unicity distance for an affine cipher is 33.

Let's solve your equation step-by-step.

−6=3/8x−2+

1/8x

Step 1: Simplify both sides of the equation.

−6=3/8x−2+1/8x

−6=3/8x+−2+1/8x

−6=(3/8x+1/8x)+(−2)

(Combine Like Terms)

−6=1/2x+−2

−6=1/2x−2

Step 2: Flip the equation.

1/2x−2=−6

Step 3: Add 2 to both sides.

1/2x−2+2=−6+2

1/2x=−4

Step 4: Multiply both sides by 2.

2*(1/2x)=(2)*(−4)

Answer:

There are about 118868 employees at the company.

Step-by-step explanation:

When dealing with percentage problems, we can use the following equation:

P%x = y, where P% of x is y.

Since we're told that 25200 is 21.2% of the total number of employees, we substitute 21.2% for P and 25200 for y in the formula to solve for x, the total number of employees.

Furthermore, we must first convert the percentage to a decimal by dividing 21.2 by 100:  21.2 / 100 = 0.212

0.212x = 25200

Step 1:  Divide both sides by 0.212 to solve for x:

(0.212x = 25200) / 0.212

x = 118867.9245

Step 2:  Round to the nearest whole number to get the final answer.

118867.9245 rounded to the nearest whole number is 118868.  Thus, the company has about 118867 employees in total.

Step 3:  Check that 21.2% of 118868 is (exactly or approximately) 25200:

0.212 * 118868 = 25200

25200.016 > 25200

Although 25200.016 is slightly larger than 25200, we can still trust that our answer is 11868 since it's rounded and an approximation.  A more exact number like 118867.9245 would give us exactly 25200.

Answer:

Step-by-step explanation:

The two triangles are similar by the property side angle side.

If two objects are having the same shape then they will be termed as similar. So in mathematics, if two figures have the same shapes, lines or angles then they are called similar.

In geometry, two figures or objects are said to be congruent if their shapes and sizes match, or if one is the mirror image of the other. The meaning of congruency is that the two shapes are similar as well as equal in size.

Here in the triangles, the angle is equal and the sides are dilated by factor two from 18 to 9. It means that the sides are similar to each other and the angle is the same.

A function \(P(t) = 170.(1.30)^t\)  that gives the deer population P(t) on the reservation t years from now

We were told there were 170 stags on reservation. The number of deer is increasing at a rate of 30% per year.

We could see the deer population grow exponentially since each year there will be 30% more than last year.

Since we know that an exponential growth function is in form:

\(f(x) = a*(1+r)^x\)

where a= initial value, r= growth rate in decimal form.

It is given that a= 170 and r= 30%.    

Let us convert our given growth rate in decimal form.

\(30 percent = \frac{30}{100} = 0.30\)

Upon substituting our given values in exponential function form we will get,

    \(P(t) = 170.(1+0.30)^t\)

⇒ \(P(t)= 170.(1.30)^t\)

Therefore, the function \(P(t) = 170.(1.30)^t\) will give the deer population P(t) on the reservation t years from now.

The corollary states that for every positive real number ε, there exists a positive integer n such that

The corollary of the Archimedean principle states that for any positive real number ε, there exists a positive integer n such that ε is greater than the reciprocal of n, i.e., ε > 1/n. In other words, there exists a positive integer n such that the fraction 1/n is smaller than any given positive real number ε.

To prove this corollary, we can assume that ε is a positive real number. By the Archimedean principle, there exists a positive integer m such that m > ε. Now, consider the positive integer n = ⌈1/ε⌉ + 1, where ⌈x⌉ denotes the ceiling function, rounding up x to the nearest integer.

We have:

1/ε < 1/(⌈1/ε⌉ + 1) ≤ 1/(1/ε) = ε.

Therefore, we can conclude that for any positive real number ε, there exists a positive integer n = ⌈1/ε⌉ + 1 such that ε > 1/n.

The probability of either A or B occurring is 0.5. The probability that neither A nor B will happen is also 0.5.

It is given that events A and B are mutually exclusive, meaning there is no intersection that is they are independent events. In simple terms, A and B are occurring at different times.

P(A or B) = P(A) + P(B) = 0.30 + 0.20 = 0.50

So the probability of either A or B occurring is 0.5.

Also, the total probability of the event is 1.

So to find the Probability of (neither A nor B):

P complement = 1 - P(A or B) = 1 - 0.50 = 0.50

If the best fit line is nearly horizontal, it suggests no significant relationship between height and head circumference.

In this scenario, the explanatory variable is the child's height, as it is being used to predict the head circumference.

The response variable is the head circumference itself, as it is the variable being predicted or explained by the height.

To draw a scatter diagram of the data, you would plot the child's height on the x-axis and the corresponding head circumference on the y-axis. Each data point would represent a child's measurement pair.

Once all the data points are plotted, you can then draw the best fit line, also known as the regression line, that represents the overall trend or relationship between height and head circumference.

By observing the scatter diagram and the best fit line, you can determine the relationship between a child's height and head circumference.

If the best fit line has a positive slope, it indicates a positive relationship, meaning that as height increases, head circumference tends to increase as well.

If the best fit line has a negative slope, it indicates a negative relationship, meaning that as height increases, head circumference tends to decrease.

By assessing the slope of the best fit line in the scatter diagram, you can determine whether the relationship between height and head circumference is positive, negative, or nonexistent.
