1,680
Step-by-step explanation:
There are 8 students to choose for the first chair. After we choose one, we have 7 students to choose from for the second chair, 6 for the third chair, etc.
8 * 7 * 6 * 5 = 1680 (ans)
Hello.
Ken had 6.57 yards of tape, and then used 0.5 yards of the tape. Subtract 0.5 from 6.57.
6.57 - 0.5 = 6.07
He has 6.07 of the tape left.
Answer:
Jillene will spend<em> $345.60</em> in 6 months.
Step-by-step explanation:
To find the answer we will turn <em>24% into a decimal</em>. 24% ÷ 100 = <em>0.24</em>. Now <em>multiply 0.24 by $240</em> and we get<em> $57.60</em>. Because we are trying to find how much Jillene will spend in 6 months, we will <em>multiply $57.60 by 6</em>, which is $345.60. Therefore, <em>$345.60 is our answer.</em>
Answer:
f(x) = -22.45x^2 + 92.38x + 1.86
Because the points on the scatter plot show an increase in concentration from 0 hours through 2 hours and a decrease from 2 hours through 4 hours, the relationship shown is best modeled using a quadratic function.
Let's look closely at the two quadratic function choices to determine the key features of their graphs.
Because the coefficient of its x^2 -term is negative, the graph of f(x) = -22.45x^2 + 92.38 + 1.86 will be concave down and have a maximum value.
Because the coefficient of its x^2 -term is positive, the graph of f(x) = 22.45x^2 + 92.38 + 1.86 will be concave up and have a minimum value.
Because the scatter plot shown has a concave down trend, the function that best describes the relationship shown is:
f(x) = -22.45x^2 + 92.38 + 1.86

Answer:
6000
Step-by-step explanation:
2000+1000=3000
9000-3000=6000
Side note: I'm not sure if this is 100% correct because you didn't give the choices
