how can you tell two objects are similar when all you did is make the the object smaller by a scaled factor?

if good answer... will give brainly and also 5 stars and everything​

Answers

Answer 1

Answer:

You can tell if they are similar if all the angles correspond and the sides are all scaled down by the same factor. For instance, a triangle with sides of 30, 40, and 50 scaled down by a factor of 2 would have sides of 15, 20, and 25.

% compounded quarterly. After 16 years, how much more money would Angel have in his account than Jackson, to the nearest dollar?

Answers

Answer:22215

Step-by-step explanation: got it from delta math

After 16 years Angel would have amount $22942 more money in his account than Jackson.

What is compound interest?

Compound interest is the interest you earn on interest. Compound interest is the interest calculated on the principal and the interest accumulated over the previous period.

For the given situation,

Investment of Jackson, p = $81000

Rate of interest, r = 6 1/2%

⇒ [tex]6.5\% = 0.065[/tex]

Interest is compounded monthly, so n = 12

Number of years, T = 16

Investment of Angel, p = $81000

Rate of interest, r = 7 1/8%

⇒ [tex]7.125\% = 0.07125[/tex]

Interest is compounded quarterly, so n = 4

Number of years, T = 16

The formula of amount in compound interest is

[tex]A=p(1+\frac{r}{n} )^{nT}[/tex]

Jackson's amount after 16 years,

⇒ [tex]A=81000(1+\frac{0.065}{12} )^{(12)(16)}[/tex]

⇒ [tex]A=81000(\frac{12.065}{12} )^{192}[/tex]

⇒ [tex]A=81000(1.0054)^{192}[/tex]

⇒ [tex]A=81000(2.8123)[/tex]

⇒ [tex]A=227798.13[/tex]

Angel's amount after 16 years,

⇒ [tex]A=81000(1+\frac{0.07125}{4} )^{(4)(16)}[/tex]

⇒ [tex]A=81000(\frac{4.07125}{4} )^{64}[/tex]

⇒ [tex]A=81000(1.0178)^{64}[/tex]

⇒ [tex]A=81000(3.0955)[/tex]

⇒ [tex]A=250739.62[/tex]

After 16 years, how much more money would Angel have in his account than Jackson is

⇒ [tex]250739.62-227798.13[/tex]

⇒ [tex]22941.49[/tex] ≈ [tex]22942[/tex]

Hence we can conclude that after 16 years Angel would have $22942 more money in his account than Jackson.

$365.40
$185.40
$180.00
$250.00

Answers

Answer:

Compound interest = $365.4

Step-by-step explanation:

Given:

Amount borrowed = $6,000

Rate of interest = 3%

Number of year =  year

Find:

Compound interest

Computation:

A = P[1+r]ⁿ

Amount after 2 year = 6,000[1 + 3%]²

Amount after 2 year = 6,000[1 + 0.03]²

Amount after 2 year = 6,000[1.03]²

Amount after 2 year = 6,000[1.0609]

Amount after 2 year = 6,365.4

Compound interest = Amount after 2 year - Amount borrowed

Compound interest = 6,365.4 - 6,000

Compound interest = $365.4

for solve the bracket we have to multiply 1/5 for x and for -1

x+1/5x-1/5 = 1

now we have to multiply the two members of the equation by 5

5(x+1/5x-1/5) = 5

5x + x - 1 = 5

now we have to sum 1 at both members

5x + x -1+1 = 5+1

6x = 6

at least we have to divide the two members by 6

x = 1 that is the solution of the equation

help please triangles and trig

Answers

Answer:

[tex]\sin L = \frac{3}{5}[/tex]

[tex]\tan N = \frac{4}{3}[/tex]

[tex]\cos L = \frac{4}{5}[/tex]

[tex]\sin N = \frac{4}{5}[/tex]

Step-by-step explanation:

Given

The above triangle

First, we calculate the length LM using Pythagoras theorem.

[tex]LN^2 = LM^2 + MN^2[/tex]

[tex]10^2 = LM^2 + 6^2[/tex]

[tex]100 = LM^2 + 36[/tex]

Collect like terms

[tex]LM^2 = 100 - 36[/tex]

[tex]LM^2 = 64[/tex]

Take positive square root

[tex]LM=8[/tex]

Solving (a): Sin L

[tex]\sin L = \frac{Opposite}{Hypotenuse}[/tex]

[tex]\sin L = \frac{MN}{LN}[/tex]

[tex]\sin L = \frac{6}{10}[/tex]

Simplify

[tex]\sin L = \frac{3}{5}[/tex]

Solving (b): tan N

[tex]\tan N = \frac{Opposite}{Adjacent}[/tex]

[tex]\tan N = \frac{LM}{MN}[/tex]

[tex]\tan N = \frac{8}{6}[/tex]

Simplify

[tex]\tan N = \frac{4}{3}[/tex]

Solving (c): cos L

This calculated as:

[tex]\cos L = \frac{Adjacent}{Hypotenuse}[/tex]

[tex]\cos L = \frac{LM}{LN}[/tex]

[tex]\cos L = \frac{8}{10}[/tex]

Simplify

[tex]\cos L = \frac{4}{5}[/tex]

Solving (d): sin N

This is calculated using:

If [tex]a + b = 90[/tex]

Then: [tex]\sin a = \cos b[/tex]

So:

[tex]\sin N = \cos L[/tex]

[tex]\sin N = \frac{4}{5}[/tex]
