Answer:

L = 29,550 mm

Step-by-step explanation:

i think i've done this before.. but anyway Lets make it simple and easy.

Let A = 600mm

Let B = 300mm

Let C = 16 as number turns

Let d = 20mm

L = sqrt ((3.14 * (600 - 20))² + 300³)    * 16

L = 29,550 mm

3√2 and 3 are the values of x and y respectively from the figure.

The given diagram is a right triangle with an acute angle of 45 degrees

We need to determine the values of variables x and y.

Applying the trigonometry identity, we will have:

sin 45 = opposite/hypotenuse
sin45 = 3/x

x = 3/sin45

x = 3/(1/√2)
x = 3√2

Similarly:

tan 45 = opposite/adjacent
tan 45 = 3/y

1 = 3/y

y = 3

Hence the values of x and y from the figure is 3√2 and 3 respectively

Answer:

Step-by-step explanation:

go from one point to the other. From the left point to the right point you are running across (to the right) three times. Then you are ¨rising¨ (going down) once. going to the right is positive. If you are going down its negative. Vise versa. The formula is Rise/Run. your answer would be -1/3. the one is negative because it went down.Then divide it and you have -0.333. I hope I helped!

Answer:

Step-by-step explanation:

I Honestly don't know i'm only on here to get answers.

PART A: Linda has $4.41 more than Enrique after one year.

PART B: Enrique has $12.10 more than Linda after the second year.

PART A: After one year, we can calculate the amount of money each person has in their respective accounts.

For Linda's account:

Principal amount = $610

Interest rate = 1.2%

\(Interest $ earned = Principal $ amount \times (Interest rate/100) = $610 \times (1.2/100) = $7.32\)

\(Total $ amount after one year = Principal amount + Interest earned = $610 + $7.32 = $617.32\)

For Enrique's account:

Principal amount = $590

Interest rate = 3.9%

\(Interest $ earned = Principal amount \times (Interest rate/100) = $590 \times (3.9/100) = $22.91\)

Total amount after one year = Principal amount + Interest earned = $590 + $22.91 = $612.91

Comparing the two amounts, after one year Linda has more money.

The difference in the amount is:

$617.32 - $612.91 = $4.41

Therefore, Linda has $4.41 more than Enrique after one year.

PART B: After a second year, we need to calculate the amounts again.

For Linda's account:

Principal amount = $617.32

Interest rate = 1.2%

\(Interest earned = Principal amount \times (Interest rate/100) = $617.32 \times (1.2/100) = $7.41\)

Total amount after the second year = Principal amount + Interest earned = $617.32 + $7.41 = $624.73

For Enrique's account:

Principal amount = $612.91

Interest rate = 3.9%

\(Interest earned = Principal amount \times (Interest rate/100) = $612.91 \times (3.9/100) = $23.92\)

Total amount after the second year = Principal amount + Interest earned = $612.91 + $23.92 = $636.83

Comparing the two amounts, after the second year Enrique has more money.

The difference in the amount is:

$636.83 - $624.73 = $12.10

Answer:

(5x-4)(x+1)

Step-by-step explanation:

Answer:

$475 + 4% (19 percent) = $494 a year.

Step-by-step explanation:

$8,000.00 was loaned at 3% annual interest, and $17,000.00 (25,000 - 8,000) was loaned at 9% annual interest.

Let x be the amount loaned at 3% annual interest and y be the amount loaned at 9% annual interest.

According to the problem, we know that:

x + y = 25,000

0.03x + 0.09y = 1,770.00

We can use these two equations to solve for x and y.

One way to do this is to solve for one of the variables in terms of the other in the first equation, and  substitute that expression into the second equation.

y = 25,000 - x

Substituting this expression for y into the second equation, we get:

0.03x + 0.09(25,000 - x) = 1,770.00

Simplifying and solving for x, we get:

0.03x + 2,250 - 0.09x = 1,770.00

-0.06x = -480.00

x = 8,000.00

Therefore, $8,000.00 was loaned at 3% annual interest, and $17,000.00 (25,000 - 8,000) was loaned at 9% annual interest.

Answer:

a_n = 47 - 8n

Step-by-step explanation:

a_1 = 39

a_2 = 31

a_3 = 23

31 - 39 = -8

23 - 31 = -8

This is an arithmetic sequence with constant difference -8.

a_1 = 39

a_2 = 39 - 8

a_3 = 39 - 8 - 8 = 39 - 2(8)

a_4 = 39 - 8 - 8 - 8 = 39 - 3(8)

...

a_n = 39 - (n - 1)(8)

a_n = 39 - 8(n - 1)

a_n = 39 - 8n + 8

a_n = 47 - 8n

Answer:

\(a_n=47-8n\)

Step-by-step explanation:

Given sequence:

Calculate the differences between the terms:

\(39 \underset{-8}{\longrightarrow} 31 \underset{-8}{\longrightarrow} 23\)

As the differences are constant (the same), this is an arithmetic sequence with:

\(\boxed{\begin{minipage}{8 cm}\underline{General form of an arithmetic sequence}\\\\$a_n=a+(n-1)d$\\\\where:\\\phantom{ww}$\bullet$ $a$ is the first term.\\\phantom{ww}$\bullet$ $d$ is the common difference between terms.\\\end{minipage}}\)

Substitute the found values of a and d into the formula to create an equation for the nth term of the sequence:

\(\implies a_n=39+(n-1)(-8)\)

\(\implies a_n=39-8n+8\)

\(\implies a_n=47-8n\)

Answer:

GH is parallel to KJ and GJ is parallel to HK, we have shown that both pairs of opposite sides are parallel. Therefore, GHJK is a parallelogram.

What is the parallelogram?

A parallelogram is a quadrilateral with two pairs of parallel sides. The opposite sides of a parallelogram are equal in length, and the opposite angles are equal in measure.

To prove that GHJK is a parallelogram, we need to show that both pairs of opposite sides are parallel.

From the given information, we know that GK is parallel to HJ (since they are both parallel to LG), so we can start by using this fact to show that GH is parallel to KJ:

∠GKL and ∠HJK are alternate interior angles formed by the transversal GK across the parallel lines LG and HJ.

Therefore, ∠GKL ≅ ∠HJK.

Similarly, we can use the fact that LG is parallel to GK to show that GJ is parallel to HK:

∠ZGL and ∠KHG are alternate interior angles formed by the transversal HG across the parallel lines LG and GK.

Therefore, ∠ZGL ≅ ∠KHG.

Hence, GH is parallel to KJ and GJ is parallel to HK, we have shown that both pairs of opposite sides are parallel. Therefore, GHJK is a parallelogram.
