Queremos encontrar la escala que se ha utilizado para la elaboración de la maqueta.
Veremos que la escala utilizada es 1cm = 0.5m
Para encontrar la escala, tenemos que ver la relación entre la medida de la maqueta y la medida real.
Sabemos que:
largo en la maqueta = 90cmlargo real = 45mLo que tenemos que ver es cuanto representa cada centimetro en la maqueta.
Asi, tenemos la relación:
90cm = 45m
90cm/90 = 45m/90
1cm = 0.5m
Es decir, cada centimetro en la maqueta representa 0.5 metros en la realidad, es decir, la escala utilizada es:
1cm = 0.5m

Have a GREAT day and remember to take care of yourself!
The required trigonometric function is cos x.
Given that cosec x cot x [tex](1-cos^{2}x )[/tex].
By using trigonometric identities [tex]cos^{2}x + sin^2x=1[/tex],
that gives [tex]1-cos^2x=sin^2x[/tex]. -----(1)
By using the trigonometric functions,
cosec x = [tex]\frac{1}{sin x}[/tex] -------(2)
cot x = [tex]\frac{cos x}{sin x}[/tex] -----------(3)
By substituting equation 1, 2 and 3 in the given expression,
That implies, cosec x cot x [tex]sin^{2}x[/tex] = [tex]\frac{1}{sin x}[/tex] × [tex]\frac{cos x}{sin x}[/tex] × [tex]sin^2 x[/tex]
On algebraic simplifying gives,
cosec x cot x [tex]sin^{2}x[/tex] = [tex]\frac{cos x}{sin^2 x}[/tex] × [tex]sin^2 x[/tex]
On simplifying trigonometric functions gives,
cosec x cot x [tex]sin^{2}x[/tex] = cos x.
Hence, the required trigonometric function is cos x.

Acelynn borrows $1337 to buy a four-wheeler. The annual
intrest rate is 4% for the 14-year loan.How many intrest
will she payfor the money borrowed?
Answer:
$748.72
Step-by-step explanation:
Multiply 1337 times 4%
4% = 0.04
1337 x 0.04 = 53.48
Multiply the product by the amount of years -
53.48 x 14 = 748.72
She will pay back $748.72 intrest for the money borrowed.
The interest rate is 4%. So, it can be written as 0.04
$1337 × 0.04 × 14 = 748.72
So, she'll pay $748.72 interest for the borrowed money...

Use the Binomial Theorem to expand the expression (a - 4)5. Choose the correct polynomial.
Step-by-step explanation:
a⁵-5×a⁴×(-4)-10×a³×-(4)²-10×a²×(-4)³-5×a×(-4)⁴-(-4)⁵
=a³-20a⁴+160a³-640a²+1280a-1024
The required expansion of the binomial theorem will be as:
(a - 4)⁵ = a³-20a⁴+160a³-640a²+1280a-1024.
What is the Binomial Theorem?The binomial theorem states the principle for expanding the algebraic expression (x + y)ⁿ and describes it as the total of the phrases involving the unique exponents of the x and y variables. Each word in a binomial expansion has a coefficient, which is a numerical value.
The expression is given in the question following as:
(a - 4)⁵
[tex](a-4)^5=\frac{5!}{0!\left(5-0\right)!}a^5\left(-4\right)^0+\frac{5!}{1!\left(5-1\right)!}a^4\left(-4\right)^1+\frac{5!}{2!\left(5-2\right)!}a^3\left(-4\right)^2+\frac{5!}{3!\left(5-3\right)!}a^2\left(-4\right)^3+....[/tex]
⇒ a⁵-5×a⁴×(-4)-10×a³×-(4)²-10×a²×(-4)³-5×a×(-4)⁴-(-4)⁵
⇒ a³-20a⁴+160a³-640a²+1280a-1024
Therefore, the required expansion of the binomial theorem will be as:
(a - 4)⁵ = a³-20a⁴+160a³-640a²+1280a-1024.
Hence, the correct answer would be an option (A).
