Answer:
El número resultante es 902 billones 43 mil millones. (
)
Step-by-step explanation:
Antes de proceder a escribir a resolver este problema, debemos recordar las siguientes equivalencias:
<em>Una decena de millares de millón</em> - 10.000'000.000
<em>Una centena de billón</em> - 100'000.000'000.000
<em>Una unidad de billón</em> - 1'000.000'000.000
<em>Un millar de millón</em> - 1.000'000.000
El ejercicio consiste en sumar las cantidades dadas para obtener el total, es decir:
El número resultante es 902 billones 43 mil millones. ()
<h3>
Answer:</h3>
x=2
<h3>
Solution:</h3>
- In order to isolate x, we should first of all take the square root of both sides.
- If we take the square root of the left-hand side, we will get
- How about the right-hand side? Well, we should take the square root of the numerator (9) and the denominator (4)
- So we have
- Move -1/2 to the right:
- x=2

Answer:
The cost of tuition as a function of x, the number of years since 1990, is C(x)= 14*(x-1990) + 95
Step-by-step explanation:
A linear function is a polynomial function of the first degree that has the following form:
y= m*x + b
where
- m is the slope of the function
- n is the ordinate (at the origin) of the function
So, in this case: C(x)= m*( x-1990) + b where x is the number of years since 1990.
Given the coordinates of two points, it is possible to determine the slope m of the line from them using the following formula:
In this case, you know that in 1990, the cost of tuition at a large Midwestern university was $95 per credit hour. And in 1999, tuition had risen to $221 per credit hour. So:
- x1= 1990
- y1= 95
- x2= 1999
- y2= 221
So the value of m is:
m= 14
So C(x)= 14*( x-1990) + b. In 1999, tuition had risen to $221 per credit hour. Replacing:
221= 14*(1999 - 1990) + b
221= 14*9 +b
221= 126 + b
221 - 126= b
95= b
Finally, <u><em>the cost of tuition as a function of x, the number of years since 1990, is C(x)= 14*(x-1990) + 95</em></u>

if two angles sum is 90 degree their name the relationship must be vertical.
a+b=90
