1. Elissa is buying a new car. She has an excellent credit score of

k0ka [10]

Answer:

$273.38 per month

Step-by-step explanation:

<u>Monthly Payment Formula</u>

$\sf PMT=\dfrac{Pi(1+i)^n}{(1+i)^n-1}$

where:

PMT = monthly payment
P = loan amount
i = interest rate per month (in decimal form)
n = term of the loan (in months)

Given:

P = $19,500 - $4,000 = $15,500
i = 2.25% / 12 = 0.0225 / 12
n = 5 years = 60 months

$\implies \sf PMT=\dfrac{15500 (\frac{0.0225}{12})(1+\frac{0.0225}{12})^{60}}{(1+\frac{0.0225}{12})^{60}-1}$

$\implies \sf PMT=273.3788438$

$\implies \sf PMT=\$273.38$

If you add 21 to my number and then multiply the result by 3, you will get 84 more than two-thirds of my number. Find my number.

Ksivusya [100]

Based on the calculations, the unknown number is equal to $\frac{-45}{7}$

Let the unknown number be x.

<h3>How to find an unknown number:</h3>

Translate the word problem into an algebraic expression, we have;

Adding 21 to the unknown number:

$21 +x$

Multiplying the result by 3:

$3\times (21+x)$

84 more than two-thirds of the unknown number:

$\frac{2x}{3} +84$

Equating the equations, we have:

$3\times (21+x) = \frac{2x}{3} +84\\\\43+3x=\frac{2x}{3} +84$

Cross-multiplying, we have:

$43+3x=\frac{2x}{3} +84\\\\129+9x=2x+84\\\\9x-2x=84-129\\\\7x=-45\\\\x=\frac{-45}{7}$

Csc\theta -cot\theta =\frac{sin}{1+cos\theta }

Inga [223]

Answer:

Step-by-step explanation:

Left Hand Side

Change to sin(theta) and cos(theta)

csc(theta) = 1/sin(theta)

cot(theta) = cos(theta)/sin(theta)

1/sin(theta) - cos(theta)/sin(theta) Put over Sin(theta) Common denominator

[1 - cos(theta)] / sin(theta) Multiply numerator and denominator by 1 + cos(theta)

(1 - cos(theta)(1 + cos(theta) ) / sin(thata)*(1 + cos(theta))

(1 + cos(theta)(1 - cos(theta)) = 1 - cos^2(theta)

sin^2(theta) / (sin(theta)* ( 1 + cos(theta)

sin(theta) / (1 + cos(theta) )

Right hand Side.

See Above.
