Answer:
y = 60x + 22
262 miles
Step-by-step explanation:
Given that the car enters the turnpike at 22 miles, his initial starting point, or initial value (b) is 22. You also know the rate at which the car travels is 60 miles per hour, which is the slope (m). Using the slope-intercept formula of a linear function: y = mx + b, you can plug in your initial value and rate:
y = 60x + 22, where y = the total miles and x = the number of hours traveled
After 4 hours:
y = 60(4) + 22 = 240 + 22 = 262 miles
Answer:
2.8592933268
Step-by-step explanation:
tan(72) = 8.8/x
=> x = 8.8/tan(72) = 2.859293326849
Answer:
x=2
Step-by-step explanation:
Since they are both equal to y set them equal to each other: 2x-3=-8x+17
Subtract 17 from both sides: 2x-20=-8x
Subtract 2x from both sides: -20=-10x
Divide both sides by -10: 2=x
c. they are all parts of 12, and when added together they equal 11/12. The formula to solve non proportionate fractions*or with different denominators* is to CROSS multiply and make the denominators equal, then add the numerators and SIMPLIFY.
*Cross multiply to make the denominator equal (you can google how to make fractions equal)
then add the numerators together
then simplify. PLEASE BE CONSIDERATE OF THE FORMULA AND DONT BE INTIMIDATED BY THE LOOK OF THE PROBLEM. They all have the same formula or method of solving. Good Luck!! I hope this helps.
The colony doubles every hour, the population is equal to
p = 2^t
<span>Where t </span><span>is the time in hours.</span>
We are able to see this because:
2^0 = 1
2^1 = 2
2^2 = 4
Notice that the x coordinate of the graph corresponds to the time, and the y coordinate corresponds to the population.
<span>Thus at t = 9
</span>p = 2^t
p = 2^9
p = 512.
The correct answer is 512.
