Write an equation that has of constant of proportionality of 15.

hoa [83]

Hello there! The formula for constant of proportionality is k = y/x, which also is k = slope.

Equations with a constant of proportionality of 15 would be:

• k = 15/1

• k = 30/2

•k = 75/5

and so on. Anything that is a multiple of 15 and is placed as the numerator over the dividend used to receive a quotient of 15 would work. Hope this helps!

In ΔLMN, l = 870 cm, ∠N=117° and ∠L=17°. Find the length of n, to the nearest 10th of a centimeter.

MAXImum [283]

We have been given that in ΔLMN, l = 870 cm, ∠N=117° and ∠L=17°. We are asked to find the length of n to the nearest 10th of a centimeter.

We will use law of sines to find the length of n.

Law of sine states the relation between the angles of a triangle and their corresponding side.

$\frac{a}{\text{sin(A)}}=\frac{b}{\text{sin(B)}}=\frac{c}{\text{sin(C)}}$ , where a, b and c are corresponding sides to angles A, B and C respectively.

Upon using law of sines, we will get:

$\frac{n}{\text{sin(N)}}=\frac{l}{\text{sin(L)}}$

$\frac{n}{\text{sin}(117^{\circ})}=\frac{870}{\text{sin}(17^{\circ})}$

$\frac{n}{0.891006524188}=\frac{870}{0.292371704723}$

$\frac{n}{0.891006524188}\times 0.891006524188=\frac{870}{0.292371704723}\times 0.891006524188$

$n=2975.66414925226\times 0.891006524188$

$n=2651.336170776$

$n\approx 2651.3$

Therefore, the length of n is approximately 2651.3 cm.

a country's population in 1994 was 52 million in 2000 it was 55 million estimate the population in 2003

atroni [7]

[email protected] = 52,000,000
[email protected] = 55,000,000
[email protected] = ?
r = ?

Equation: P = Po * e^(rt)
-----
Solve r:
P/Po = e^(rt)

ln(P/Po) = rt
r = ln(P/Po)/t
r = ln([email protected]/[email protected])/(2000-1994)
r = ln(55M/52M)/6
r = 0.009348

----
Solve for [email protected]
t = 2003 - 1994 = 9

[email protected] = [email protected] * e^(rt)
[email protected] = 52M * e^(0.009348*9)
[email protected] = 56,564,292.9

approximately 57M.
