The linear function that calculates the expected distance from the sun of the Voyager-2 spacecraft in x years after 1990 is given by:
y = 3.3x + 30.6.
<h3>What is a linear function?</h3>
A linear function is modeled by:
y = mx + b
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.
In this problem, we have that the distance increases 33 AU each 10 years, hence the slope is given by:
m = 33/10 = 3.3.
Hence:
y = 3.3x + b.
When x = 28, y = 123, hence we use it to find b as follows:
123 = 3.3(28) + b
b = 30.6.
Hence equation to calculate the expected distance from the sun of the Voyager-2 spacecraft in x years after 1990 is given by:
y = 3.3x + 30.6.

#SPJ1
Lamborghini=
fraction = 2/32
Decimal = 0.0625
Percentage= 6.25%
Corvette=
Fraction= 4/32
Decimal=0.125
Percentage=12.5%
Explanation:
Since the problem says “lamborghini OR corvette” you need to add the probability amount of both cars together. There are 2 lamborghinis and 4 corvettes, so 2+4=6. Now, put this number over the total amount of all cars. 6+2+4+8+12=32. So, the probability will be 6/32 which simplifies to 3/16. In decimal form this is .1875, and in percent form this is 18.75% (move the decimal 2 places to the right)
Answer:
7.81*10^11
Step-by-step explanation:
1.86*10^5=186,000
186,000*4,200,000=7.81*10^11
Answer:
50 miles
Step-by-step explanation:
x = (30 - 5) / 0.50
<em>Subtract To Solve Parentheses</em>
x = 25 / 0.50
<em>Divide</em>
x = 50
