An N-scale model railroad caboose is 3 inches long. N scale is 169 feet to 1 foot.

hammer [34]

9514 1404 393

Answer:

c/3 = 169/12
42 1/4 feet

Step-by-step explanation:

Since we want to know the actual number of feet, we can write the proportion with that in the numerator.

$\dfrac{\text{actual feet}}{\text{scale inches}}=\boxed{\dfrac{c}{3}=\dfrac{169}{12}}\\\\c=\dfrac{3\cdot169}{12}=42\frac{1}{4}\qquad\text{multiply by 3}$

The real caboose is 42 1/4 feet long.

4000 principle earning 6% compounded annually after 5 years

Dmitrij [34]

Principal, P= 4000
interest = 6%/4 = 0.015 (per quarter)
Number of periods, n = 5*4 =20 quarters

Compound interest formula:
Future value:
$F=P(1+i)^n$
$=4000(1+.015)^{20}$
$F=5387.42$ to the nearest cent.

A circle has center at (7, 0). What is the equation of the line that is tangent to the circle at (2, 0)?

IgorC [24]

First find equation
center is (h,k) then
(x-h)^2+(y-k)^2=r^2
given
(7,0) is center
(x-7)^2+y^2=r^2
also given (2,0)
(2-7)^2+0^2=r^2
(-5)^2=r^2
25=r^2

(x-7)^2+y^2=25 is equation

take derivitive of both sides, implicit differntiaton
2(x-7)+2y dy/dx=0
2(x-7)=-2y dy/dx
(7-x)/y=dy/dx
at (2,0)
(7-2)/0
undefined
that means the line is x=something
(2,0)
the equation is x=2

Given: b = 600, B = 11°, C = 75° in triangle ABC; find C. (Round the answer to the nearest whole number.)

Slav-nsk [51]

Answer:

The answer to your question is the letter B. 3,037

Step-by-step explanation:

Data

b = 600

B = 11°

C = 75°

c = ?

Process

1.- To solve this problem, use the law of sines

b/sin B = c/sin C

2.- Solve for c

c = b sin C / sin B

3.- Substitution

c = 600 sin 75 / sin 11

4.- Simplification

c = 600 (0.966) / 0.191

c = 579.55 / 0.191

5.- Result

c = 3037
