Answer:
a rational number
Step-by-step explanation:
3.4 is a terminating decimal. That means that after the 4 in 3.4 there are no other numbers (the number "ends" after the 4) Also, 3.4 can be written as a RATIO of two numbers (looks like a fraction)
3.4 = 3 4/10 = 3 2/5
= 15/5 + 2/5
= 17/5
If you put 17÷5 in a calculator it would say 3.4
3.4 = 17/5
3.4 is a rational number.
Hi there! I can help you! Okay, so to find the answer for these types of questions, we have to divide the total cost on gas by the number of gallons filled in the tank. With that being said, if you do this correctly, here are your answers.
Genevieve: $3.68
Unnamed Person: $3.64
When you compare the prices, you see that 3.64 < 3.68. With this being the case, the unnamed person spent less per gallon of gas.
Answer:
5.025m
Step-by-step explanation:
The clothesline also creates an upside-down triangle with two sides being 5m, 0.5m, and the hypotenuse being the clothesline.
We can use the pythagorean theorem to find the length of the clothesline.
5 squared +.5 squared= the length of the clothesline squared
25+.25= the square root of 25.25
= 5.025
Answer:
The one that gives us the fastest y-intercept is "b". The coordinates are (0,15).
Step-by-step explanation:
In order to check which form gives us the fastest y-intercept value, let's apply x = 0 in all three of them and check how many operations we need to do to get our desired results.
a) f(x) = -3*(x - 2)² + 27
f(0) = -3*(0 - 2)² + 27
f(0) = -3*(4) + 27
f(0) = -12 + 27
f(0) = 15
b) f(x) = -3*x² + 12*x + 15
f(0) = -3*(0)² + 12*(0) + 15
f(0) = 15
c) f(x) = -3*(x + 1)*(x - 5)
f(0) = -3*(0+1)*(0-5)
f(0) = -3*(-5)
f(0) = 15
The fastest one is "b". Since it is in the standard second degree equation form "a*x² + b*x + c", we could have checked immediately by the value of "c".
The y-interecept is (0,15).
