Answer: I think the answer would be (2, -1)
Cos<span> 42° ~ 0.743
cos 42° = sin(90-42) = sin 58°
So sine of complementary angle also has same value as cos 42.
So sin 58 ~ 0.743

Answer:
7
Step-by-step explanation:
"a certain whole number" is a number that we don't know, so pick a variable, let's use n
"Twice" means two times, so we'll use 2n for this.
"subtracted from" means the 2n will be AFTER the minus sign.
____ - 2n
What goes in front? "3 times the square of the number" 3n^2
Now we have 3n^2 - 2n
Lastly, we see the result is 133. So this gives us:
3n^2 - 2n = 133 To solve, subtract 133 from both sides of the equation.
3n^2 -2n - 133 = 0 Next FACTOR.
(3n + 19)(n - 7) = 0
3n+19=0 and n-7=0
n=-19/3 and n=7
Since we are looking for a whole number choose n=7
Divide 18000 by 24= get a calculater
En una ecuación definimos como "factor" a la constante que multiplica una variable, o a un termino multiplicativo dado.
Veremos que Ernesto quiere que le presten 3,080 pesos.
Aqui sabemos que Ernesto tiene una cantidad X. Y quiere que le presten esa cantidad aplicandole un factor 8, entonces lo que el quiere es:
8*X
Sabiendo que esa cantidad es 385 pesos, reemplazamos:
8*(385 pesos) = 3,080 pesos.
Ernesto quiere que le presten 3,080 pesos.
