Step-by-step explanation:
g(x) = 3x² + 2x - 1
g(-1) = 3(-1)² + 2(-1) - 1
= 3(1) -2 -1
= 3 - 3
= 0
Answer: Hammer reaches river after 15.8 seconds.
Step-by-step explanation:
Use formula: t = square root of h divided by 4. In this problem h = 4,000.
Therefore,
T = square root of 4,000 divided by 4.
T = 15.8 seconds
We know that GCF stands for Greatest Common Factor and hence we need to apply this in solving the given problem. The solution is shown below:
54x+8154x+81
Combine same terms, we have:
8208X+81
Factoring with the greatest common factor which is 27
304x+3
The answer for the factored expression is 304X + 3.
It would be option 4) 2 because the line is perpendicular hope this helps!!
Answer:
Costco has the better deal.
Step-by-step explanation:
Find the unit rate for Costco:
<em>Remember, the unit rate is when one of the numbers in a ratio is 1.</em>
<em />
Toilet paper : Price
6 : 4.99
(divide both sides by 6)
1 : .83
<em>Remember to round to the nearest hundredth place because money only goes two places after the decimal point.</em>
<em />
Therefore, 1 roll of toilet paper at Costco costs 83 cents.
Find the unit rate for Target:
Toilet paper : Price
8 : 6.99
(divide both sides by 8)
1 : .87
Therefore, 1 roll of toilet paper at Target costs 87 cents.
Conclusion:
.83 < .87
In conclusion, Costco has a better deal because toilet paper is cheaper per roll.
