Every state has different requirements for obtaining a high school diploma. And each school varies greatly in what type of classes they offer. There are, however, a number of classes that are available, and perhaps even mandatory, in most high schools.

The courses your teen takes will also vary depending on his plans beyond high school. Students who plan to go to college may be required to take more years of a foreign language. Or a student who plans to major in engineering may want to take more math and science classes to prepare for college.

Students in a vocational track may be able to gain some hands-on learning. Many of them are even able to gain certificates or licenses that will help them in their future careers.

It's important to talk to your teen about her aspirations. Help her explore various career options.

Also, talk about what courses she plans to take in high school. Discuss her interest areas and review her schedule together. In addition to the basic classes, there are usually plenty of opportunities for your teen to take electives in various areas of study.

Answer: Residuals and scatter plots and other stuffs.

Answer:

7. 46.39 miles

8. 109 cm

9. 18 cm

Step-by-step explanation:

7. Look at the attached picture so you can picture the scenario.

The distance from City A to City B is 85 miles North. Notice that the plane only got to travel 20 miles North because of a cloudbank and redirected 108 degrees NORTH OF EAST, 20 miles towards that direction.

The new path makes a triangle, as shown in the picture.

The angle of the triangle was solved this way.

108° - 90° = 18°

The length of a was solved by getting how many miles the plane didn't travel in its original path.

85 miles - 20 miles = 65 miles.

So now we have our new given:

a = 65 miles

b = 20 miles  

c = ?

C = 18°

Using the cosine law we can solve for the c, which is the distance of the plane from City B.

[tex]c^{2}=a^{2}+b^{2}-2abCosC\\\\c^{2}=65^{2}+20^{2}-2(65)(20)Cos18\\\\c^{2}=4225+400-2600(Cos18)\\\\c^{2}=4625-2472.75\\\\\sqrt{c^{2}}=\sqrt{2152.25}\\\\c=46.39miles[/tex]

8. Again look at the attached. So as you can see we make another triangle. We can solve this with the cosine law once again. Just remember that the longer diagonal is opposite the biggest angle.

Given that:

a = 54cm

b = 78 cm

C = 110°

[tex]c^{2}=a^{2}+b^{2}-2abCosC\\\\c^{2}=54^{2}+78^{2}-2(54)(78)Cos110\\\\c^{2}=2916+6084-8424(Cos110)\\\\c^{2}=9000-(-2281.18)\\\\\sqrt{c^{2}}=\sqrt{11881.18}\\\\c=109cm[/tex]

9. Again, the shorter diagonal is facing the smaller angle. But we use the same cosine law to find it, but we use the formula of a, since a is what we are missing.

Given that:

a=?

A = 58°

b = 21cm

c= 15cm

[tex]a^{2}=b^{2}+c^{2}-2bc(CosA)\\\\a^{2}=21^{2}+15^{2}-2(21)(15)(Cos58)\\\\a^{2}=441+225-630(Cos58)\\\\a^{2}=666-333.85\\\\\sqrt{a^{2}}=\sqrt{332.15}\\\\a = 18cm[/tex]

Answer:

option 1 is correct:

y = -5cos(2x - π)

Simplif 1/2t to t/2

t/2 + 8 = 5/2t - 10

Simplify 5/2t to 5t/2

t/2 + 8 = 5t/2 - 10

Multiply both sides by 2

t + 16 = 5t - 20

Subtract t from both sides

16 = 5t - 20 - t

Simplify 5t - 20 - t to 4t - 20

16 = 4t - 20

Add 20 to both sides

16 + 20 = 4t

Simplify 16 + 20 to 36

36 = 4t

Divide both sides by 4

36/4 = t

Simplify 36/4 to 9

9 = t

Switch sides

t = 9

Answer:

t = 9.

Step-by-step explanation:

1/2 t + 8 = 5/2 t - 10

         - 8      -5/2 t

1/2 t - 5/2 t   =   -10 - 8

-2t = -18

t = 9.

Answer:

n = 28

Step-by-step explanation:

3/4n - 18 = 1/4n - 4 (eliminate fractions by multiplying each value by 4)

(3/4n * 4) - (18 * 4) = (1/4n * 4) - (4 * 4)

3n - 72 = 1n - 16 (move values with variable to same side)

3n - 1n - 72 = 1n - 1n -16

2n - 72 = -16 (move numeric values to same side)

2n - 72 + 72 = -16 + 72

2n = 56  (isolate n by dividing out the 2)

2n/2 = 56/2

n = 28

Given a rectangle with a perimeter of 24 ft where the length is 4 ft longer than the width, we find that the length is 8 ft and the width is 4 ft by setting up and solving an equation based on the formula for the perimeter of a rectangle.

The subject of this question is about finding the length and width of a rectangle given the perimeter and a relationship between the length and width. The formula for the perimeter of a rectangle is 2 * (length + width). If a rectangle has a perimeter of 24 ft, and the length is 4 ft longer than the width, we can add the length and width together and multiply by 2 to calculate the perimeter.

Let's call the width 'w'. Then the length will be 'w + 4'. From the information given, we have:

Therefore, the width of the rectangle is 4 ft. This means that the length, which is 4 ft longer than the width, is 4 + 4 = 8 ft. So the length of the rectangle is 8 ft.

Step-by-step explanation:

Odd numbers are any numbers that end with 1, 3, 5, 7, 9.

Out of the numbers inbetween 75 & 100, the odd numbers are:

75, 77, 79, 81, 83, 85, 87, 89, 91, 93, 95, 97, 99,

which makes 13.

Set the amount of numbers you got over the total amount.

13/27

You have a 13/27, or 48.15% chance of picking an odd number.

~

The numbers you are looking for are 23, 25, and 27. Let's start by defining a variable.  Let x be the first of the three odd numbers.  Since odd numbers are 2 apart, that means that the other two numbers are x + 2 and x + 4.

Now, their sum is x + (x + 2) + (x + 4) which equals 3x + 6.

Decrease that by the second number, x + 2.  That means:  3x + 6 - (x + 2), which is equal to 2x + 4.

So now we know that 2x + 4 = 50, and we can solve that easily:

2x + 4 = 50

2x = 46

x = 23

Therefore, the three odd numbers are 23, 25, and 27. Hope this helps! Please mark Brainliest. Thank you v much! :)

The answer to the problem is the three consecutive odd integers 23, 25, and 27.

Let's solve the problem step by step. We are looking for three consecutive odd integers. A useful way to express consecutive odd integers algebraically is as x, x+2, and x+4, where x is any odd integer.

The problem states that the sum of these integers minus the second one equals 50. This provides the equation: x + (x+2) + (x+4) - (x+2) = 50. Simplifying this equation, we get 2x + 4 = 50. We can further simplify to find that x = 23.

So, the three consecutive odd integers are 23, 25, and 27.

Just like before, we can conclude that the scale factor is

B.

Answer

6 inches separate the cities on the map

Explanation

We know that our scale factor is 1/4 inch = 1 mile, so we can create a conversion factor to convert 24 miles to inches. Since we need to convert from miles to inches, the denominator of our conversion factor must be 1 mile so we can cancel miles out. Notice that we can also express 1/4 inch as 0.25 inch to simplify our calculations:

We can conclude that if the conversion factor is 1/4 inch = 1 mile, 6 inches separate the cities on the map.

Answer:

8(157x^6 - 1)

Step-by-step explanation:

1256x^6 - 8

Start by factoring out a common factor. 1256 and 8 are both divisible by 8.

1256x^6 - 8 = 8(157x^6 - 1)

157 is prime, so 157x^6 - 1 is not factorable.

Answer: 8(157x^6 - 1)

I think that 2/4 would be bigger because 2/4 is the same as 1/2 and 1/2 is bigger than 1/8. Imagine a pizza, if i have 1/2 of a whole pizza i would have more pizza than a friend who had 1/8 of the whole pizza.

I hope this helps :)

If you simplify 2/4, you will get 1/2. 1/2 is bigger than 1/8.

Proof:

Draw 2 mental circles in your head. then draw lines that will make the circles out of 2 and out of 8. Now color in 1/2 of the first circle and 1/8 of the second circle. You can see that the 1/2 is bigger than the 1/8.

Final answer:

The maximum value of the quadratic function y = -2x^2 - 16x - 29 is 3, occurring at x = -4, found by determining the vertex of the parabola, which opens downwards due to the negative coefficient of the x^2 term.

Explanation:

To find the maximum or minimum value of the quadratic function y = -2x² - 16x - 29, we can utilize the properties of parabolas. Since the coefficient of the x² term is negative, the parabola opens downwards, meaning the vertex will give us the maximum value. The vertex of a parabola given by y = ax² + bx + c is found at the x-coordinate x = -b/(2a). Substituting the values from the given equation:

x = -(-16)/(2*(-2)) = -16/(-4) = -4

Now, we substitute this value back into the original equation to find the y-coordinate of the vertex:

y = -2(-4)² - 16(-4) - 29

y = -2(16) - 64 - 29

y = -32 + 64 - 29

y =3

Therefore, the maximum value of the function is 3, and it occurs at x = -4.

Equation that can find the value of the car on December 31, 2017 is:

A= 25000*(1-0.15)^7 and the value of car after 7 years is $8014.427.

Step-by-step explanation:

Price of car = $ 25,000

Rate of depreciation = 15 %

Formula used:

A= P(1-r)^n

where p= price of car

A= new price of car after depreciation

r = rate of depreciation i.e. 15/100 = 0.15

n= time in years 2017 - 2010 = 7 years

Putting values in formula:

A= 25000*(1-0.15)^7

A= 25000*(0.85)^7

A= $8014.427

So, Equation that can find the value of the car on December 31, 2017 is:

A= 25000*(1-0.15)^7 and the value of car after 7 years is $8014.427.

Answer:

√245 or 15.65247...

Step-by-step explanation:

a² + b² = c²

14² + 7² = c²

196 + 49 = c²

245 = c²

√245 ≈ c

When you have a right triangle, you can use the Pythagorean Theorem to find the missing side length. (but it only works for RIGHT triangles)

Pythagorean Theorem:

a² + b² = c²         Since you know a=14 and b=7, plug it into the equation

(14)² + (7)² = c²

196 + 49 = c²

245 = c²

√245 = c    or 15.6524758425 = c
