Answers

Answer:

C)

Step-by-step explanation:

Well, we know for the first polygon that the short side of the rectangle is 3 and for the second polygon the short side is 6, this means that for the second polygon, all sides will be double of the other side. 2 times the long side of the first rectangle is 18, this is why x = 18.

Answers

Answer:

f=5

Step-by-step explanation:

4(f-3)=20     distribute

4f-12=20      add

4f-12+12=20+12... 4f=32   divide

4f/4=20/4..... f=5

Answer:

F=8

Step-by-step explanation:

DIVIDE BOTH SIDES BY 4

4(f-3)=20     Dividing 4(f-3) by 4 cancels out the 4 leaving it f-3

                    Dividing 20 by 4 =5

f-3=5   move the constant to the right  (constant is the 5)

f=5+3   calculate

f=8

if 4(x-1)=8(x-2),then x=​

Answers

4(x-1)=8(x-2)

multiply the first bracket by 4

(4)(x)=4

(4)(-1)=-4

multiply the second bracket by 8

(8)(x)=8x

(8)(-2)=-16

4x-4=8x-16

move 8x to the other side ( in other words combine like terms)

sign changes from +8x to -8x

4x-8x-4=8x-8x-16

-4x-4=-16

move -4 to the other side

-4x-4+4=-16+4

-4x=-12

divide both sides by -4 to get x by itself

-4x/-4=-12/-4

x=3

answer:

x=3

Answer:

x = 3

Step-by-step explanation:

4( x - 1) =8

4x - 4 = 8

   + 4  + 4

4x = 12

x = 3

8 ( x - 2 )

8 ( 3 - 2 )

24 - 16

= 8

true or false: to find the second derivative of a function take the derivative of the furst derivative if the function

Answers

Answer:

True

Step-by-step explanation:

The second derivative of an implicit function can be found using sequential differentiation of the initial equation F(x,y)=0. At the first step, we get the first derivative in the form y′=f1(x,y). On the next step, we find the second derivative, which can be expressed in terms of the variables x and y as y′′=f2(x,y).

The Venn diagram represents the Quantum Physics High School student body. Circle A represents all students enrolled in extracurricular activities. Circle B represents all female students. There are 117 female students enrolled in extracurricular activities, and the enrollment of the high school is 1,000 students. There are 450 male students. How many female students are not enrolled in extracurricular activities?

A.
117
B.
433
C.
550
D.
883

Answers

Answer:

total population of school = 1000

1000 - 450 males = 550 female students

550 - 200 females not in extra curriculars = 350 females in extra curriculars

350 + 90 males in extra curriculars = 440 total in extra curriculars

Circle A = 440

Circle B - overlap = 200 females not in extra curriculars

440 + 200 = 640

1000 - 640 = 370 students represented by the portion of the Venn diagram not in either circle

If you earned $240 interest on a loan of $600 at an interest rate of 5%, how many years was the loan for?

Answers

Answer:

The loan was for 8 years.

Step-by-step explanation:

It is stated that you earned $240 interest on a loan of $600 at an interest rate of 5%.

Find the duration time by using the formula

I = Pit

Here:

'I' is the interest'P' is the total principal loan'i' is the rate of interest per year't' is the total time in years

substituting I = $240, P = $600 and i = 5%

I = Pit

t = I / Pi

 = 240 / (0.05 × 600)

 = 240 / 30

t = 8 years

Therefore, the loan was for 8 years.
