Answer:
-21=24
Step-by-step explanation:
Subtract 24 from 3
-21=8+2^2
Raise 4 to the power of 2
-21=8+16
Add 8 and 16
-21=24
1.999… is exactly the number 2.
Let <em>x</em> = 1.999… . Then 1000<em>x</em> = 1999.999… . Subtract <em>x</em> from this to eliminate the fractional part, and you get
1000<em>x</em> - <em>x</em> = 1999.999… - 1.999…
1000<em>x</em> - <em>x</em> = 1999 - 1
999<em>x</em> = 1998
<em>x</em> = 1998/999 = 2/1 = 2
So <em>p</em> = 2 and <em>q</em> = 1.
Answer: El valor de la variable b es de b = -1
Step-by-step explanation:
Para poder obtener el valor de la variable b, debemos efectuar una separación de términos, paso por paso:
1.- Reescribimos la ecuacion:
7b - 2/5 = 6b - 7/5
2.- Agrupamos variables del lado izquierdo y términos independientes del lado derecho
7b - 6b = 2/5 - 7/5
3.- Resolvemos la operaciones y obtenemos su valor directo
b = -5/5 simplificamos
b = -1 es el valor de la variable b

Answer:
y = 15·2.1599^x
Step-by-step explanation:
We know that the number changed by the ratio 1523/15 = 101.5333... in 6 days, so the daily multiplier is the 6th root of this:
b = 101.5333...^(1/6) = 2.1599 . . . rounded to 4 dp
Of course, the coefficient 'a' in the equation is the initial number, 15.
Your exponential equation is ...
y = 15·2.1599^x
a = 15
b = 2.1599
Answer:
x = 13√3
y = 13
Step-by-step explanation:
The side ratios in a 30-60-90 triangle are ...
1 : √3 : 2
In order to make the long sides match, we need to multiply these by 13:
1 : √3 : 2 = y : x : 26 = 13 : 13√3 : 26
Matching values, we find ...
x = 13√3
y = 13
