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.

(SHOW WORK)
In a survey in 2010, the population of two plant species were found to be growing exponentially. Their growth is given by these equations: species A, and species B, , where t = 0 in the year 2010.
Answer: 7 years
Step-by-step explanation:
year 1 5.75 (million) x 1.16 (16 percent ) = 6.67 motorcycles
year 2 6.67 x 1.16 = 7.7372
year 3 7.74 x 1.16 = 8.9784
year 4 8.98 x 1.16 = 10.4168
year 5 10.42 x 1.16 = 12.0834
year 6 12.09 x 1.16 = 14.0244
year 7 14.02 x 1.16 = 16.2632
year 1 3.5 (million) x 1.25 (25 percent) = 4.375
year 2 4.375 x 1.25 = 5.46875
year 3 5.47 x 1.25 = 6.8359
year 4 6.84 x 1.25 = 8.5449
year 5 8.55 x 1.25 = 10.6875
year 6 10.69 x 1.25 = 13.359375
year 7 13.36 x 1.25 = 16.7
A regular octagon has side length 10.9 in. The perimeter of the octagon is 87.2 in and the area is 573.67 in2. A second octagon has side lengths equal to 21.8 in. Find the area of the second octagon. Round to the nearest hundredth.
Answer:
2,294.66 square inches
Step-by-step explanation:
The area of an octagon is given by the formula:
A = 2 * a² * ( 1 + √2 )
So, if we input the numbers we have:
A = 2 * 21.8² * ( 1 + √2 )
A = 2 * 475.24 * (2.4142)
A = 2,294.66 square inches
As you can see, if you double the side of an octagon, its area will quadruples, which is logic since the one variable in the calculation of the area is the side's length... that is squared. So, if you double it, that double factor is squared.
It's as if we had written
A = 2 * (10.9 * 2)² * ( 1 + √2 )
A = 2 * (10.9² * 2²) * ( 1 + √2 )
which formula do you use to find the surface area of a cylinder
================================================
Explanation:
The portion that has 2pi*r^2 represents the two base areas (think of the top and bottom of a can). The 2*r*pi*h is the lateral surface area, which can be thought of as the area in which the label covers. So put together the total surface area of the entire cylinder is 2pi*r^2 + 2*r*pi*h
note: 2*r*pi*h is the same as 2pi*r*h

A train travels train travels 288 kilometre at a uniform speed. If the speed had been 4 kilometre per hour more it would have taken 1 hour less for the same journey. Find the speed of the train
Answer:
Let the speed of the train be x km/h.
Case 1:
Distance = 288 km
Speed = x km/h
Time = Distance/Speed
= 288/x h
Case 2:
Distance = 288 km
Speed = (x+4) km/h
Time = 288/x + 4 h
Since 288/x > 288/x + 4
288/x - 288/x+4 = 1
288[1/x - 1/x+4 ] = 1
[ x + 4 - x / x(x + 4) ] = 1/288
[4 / x^2 + 4x ] = 1/288
x^2 + 4x = 1152
x^2 + 4x - 1152 = 0
x^2 + 36x - 32x - 1152 = 0
x(x + 36) - 32(x + 36) = 0
(x + 36)(x - 32) = 0
x + 36 = 0 , x - 32 = 0
x = -36 , x = 32
x = -36 , rejected since speed cannot be negative.
Therefore , speed of the train = 32 km/h

For this case we must solve the following questions:
Question 1:
We must solve the following quadratic equation:
[tex]x ^ 2 + 1 = 0[/tex]
We subtract 1 from both sides of the equation:
[tex]x ^ 2 + 1-1 = -1\\x ^ 2 = -1[/tex]
We apply square root to eliminate the exponent:
[tex]x = \pm \sqrt {-1}[/tex]
The solution is not real.
[tex]x_ {1} = + i\\x_ {2} = - i[/tex]
Answer:
[tex]x_ {1} = + i\\x_ {2} = - i[/tex]
Option D
Question 2:
We must solve the following quadratic equation:
[tex]x ^ 2-10x + 24 = 0[/tex]
We factor the equation, that is, we must look for two numbers that when multiplied give as result 24 and when summed with -10. These numbers are -6 and -4:
[tex]-6-4 = -10\\-6 * -4 = 24\\(x-6) (x-4) = 0[/tex]
The roots are:
[tex]x_ {1} = 6\\x_ {2} = 4[/tex]
ANswer:
[tex]x_ {1} = 6\\x_ {2} = 4[/tex]
Option D
Question 3:
We must complete squares of the following expression:
[tex]x ^ 2-18x = 7[/tex]
We add [tex](\frac {b} {2}) ^ 2 = (\frac {-18} {2}) ^ 2 = (- 9) ^ 2[/tex]
Then:
[tex]x ^ 2-18x + (- 9) ^ 2 = 7 + (- 9) ^ 2\\x ^ 2-18x + (- 9) ^ 2 = 7 + 81\\x ^ 2-18x + (- 9) ^ 2 = 88\\(x-9) ^ 2 = 88[/tex]
Then, to complete the square, add it to both sides [tex](-9) ^ 2 = 81[/tex]

You save $8,500.00. You place 40% in a savings account earning a 4.2% APR compounded annually and the rest in a stock plan. The stock plan decreases 3% in the first year and increases 7.5% in the second year. What is the total gain at the end of the second year for both accounts combined?
Answer:
The total gain at the end of the second year for both accounts combined is $509.09.
Step-by-step explanation:
Amount saved = $8500
40% of 8500 is saved in saving account; [tex]0.4\times8500=3400[/tex]
Remainder amount in stock plan; [tex]8500-3400=5100[/tex]
Working for savings plan:
[tex]A=p(1+\frac{r}{n})^{nt}[/tex]
Here, p = 3400 ; n = 1 , t = 2 , r = 0.042
Putting values in formula:
[tex]A=3400(1+\frac{0.042}{1})^{2}[/tex]
[tex]A=3400(1+0.042)^{2}[/tex]
A = $3691.60
We get a gain of [tex]3691.60-3400=291.60[/tex] dollars
Working for stock plan:
The stock plan decreases 3% in the first year and increases 7.5% in the second year.
[tex]5100\times 0.97=4947[/tex]
When increases;
[tex]4947\times1.075=5318.03[/tex] dollars
So, we get a gain of [tex]5318.03-5100=218.03[/tex] dollars
Therefore, we have a total gain of [tex]291.06+218.03=509.09[/tex] dollars.

The sporting equipment has been sorted into baseballs and bats. The number of baseballs is four less than three times the number of bats. The equipment is 80% baseballs. Choose the equation that best represents this scenario
Answer: Second Option
[tex]\frac{x}{3x-4} = \frac{20}{80}[/tex]
Step-by-step explanation:
The baseball team is composed of bats and balls.
Call x the number of bats and call z the number of balls.
Then we know that:
The number of baseballs is four less than three times the number of bats.
This is:
[tex]z = 3x-4[/tex] (I)
Then we know that the team is 80% baseballs
This is:
[tex]\frac{x}{z} = \frac{0.2}{0.8}[/tex] (II)
We substitute the first equation in the second and we have:
[tex]\frac{x}{3x-4} = \frac{0.2}{0.8}\\\\\frac{x}{3x-4} = \frac{20}{80}[/tex]
Answer:
x/(3x-4) = 20/80

if there are 125 people and only 57 of them have pets, what percent has pets?
if we take 125 to be the 100%, what is 57 off of it in percentage?[tex]\bf \begin{array}{ccll} amount&\%\\ \cline{1-2} 125&100\\ 57&x \end{array}\implies \cfrac{125}{57}=\cfrac{100}{x}\implies 125x=5700 \\\\\\ x=\cfrac{5700}{125}\implies x = 45.6[/tex]
There are 125 people and 57 of the people have pets. What percent of people have pets.
First, we need to understand what the question is asking us to do. We know that there are 125 people altogether and only 57 of the people have pets. We are trying to figure out what percent of the people have pets.
The fraction [tex]\frac{57}{125}[/tex] is representing the 57 people who have pets out of all the people. To find what percent of people have pets, we have to change [tex]\frac{57}{125}[/tex] to a percent.
57 ÷ 125 = 0.456
0.456 × 100 = 45.6%
Therefore, 45.6% of people have have pets.
Someone help please!!!
Answer:
41.5 ft
Step-by-step explanation:
From the information given, and definition of midpoint, we know that:
AB = BC = ½ AC
AC = CE = ½ AE
CD = DE = ½ CE
GF = FE = ½ GE
HG = GE = ½ HE
AI = IH = ½ AH
AJ = JI = ½ AI
We also know:
AH = 20
HE = 14
GD = 4
Therefore:
AI = IH = 10
HG = GE = 7
AJ = JI = 5
GF = FE = 7/2
Next, since JB and IC are parallel with HE, we know that AJB and AIC are similar to AEH. So:
JB / 5 = 14 / 20
JB = 7/2
IC / 10 = 14 / 20
IC = 7
And since DF and CG are parallel to AH, then DFE and DGE are similar to AHE. So:
DF / (7/2) = 20 / 14
DF = 5
CG / 7 = 20 / 14
CG = 10
Next we know that AIB and AHC are similar, and DEG and CEH are similar.
IB / 10 = CH / 20
CH / 14 = 4 / 7
CH = 8, IB = 4.
We've found all the lengths inside triangle AEH. Adding them up:
JB + IB + IC + CH + CG + DG + DF
7/2 + 4 + 7 + 8 + 10 + 4 + 5
41.5
The total length of the inside bars is 41.5 ft.

Answer:
[tex]3 \sqrt[3]{162} = 3 \sqrt[3]{27} \sqrt[3]{6} = 3(3 \sqrt[3]{6} ) = 9 \sqrt[3]{6} [/tex]
Final answer:
The simplest form of 3 cube root of 162 is 9 cube root 2, with a=9 and b=2 after factoring out the perfect cube within 162.
Explanation:
The student has asked about simplifying the expression 3 cube root of 162 into the form a3 cube root b. The cube root of 162 can be simplified by factoring out cubes. The number 162 is equal to 2 * 81, where 81 is a perfect cube (3³). Thus, we can rewrite 162 as 2 * 3³. When taking the cube root, the cube root of 3³ is 3, and it comes out of the cube root symbol leaving us with 2 inside the cube root. Multiplying this by 3 outside the cube root, we get:
3 * 3 cube root 2 = 9 cube root 2
Therefore, the expression in its simplest form is 9 cube root 2, which follows the format a3 cube root b with a=9 and b=2.

A recursive function is a function that calls itself and takes as input the output of the previous call.
a = -2 a + 4
a1: 1
a2: -2 (1) + 4 = -2 + 4 = 2
a3: -2 (2) + 4 = -4 + 4 = 0
a4: -2 (0) + 4 = -0 + 4 = 4
a5: -2 (4) + 4 = -8 + 4 = -4
a6: -2 (-4) + 4 = 8 + 4 = 12
a7: -2 (12) + 4 = -24 + 4 = -20
