The answer is
<span>a) 1000=-16t^2+1700, implies t² = -700 /-16, and t= 6.61s
b) </span><span>970= -16t^2+1700, </span><span>implies t² = -730 /-16, and t=6.75s
c)
reasonable domain of h
h is polynomial function, so its domain is R, (all real number)
its range
the inverse of h is h^-1 = sqrt (1700- t / 16), and its domain is </span>
<span><span><span>1700- t / 16>=0, so t <1700,
the range of h is I= ]-infinity, 1700]</span> </span> </span>
Answer:
f(x)=x2,g(x)=f(3x)=(3x)2=9x2
Now to graph y=9x2. This is a parabola (U-shape), vertex at (0, 0), symmetric around y axis. When x=1/3 or -1/3, then y=1.
Hope this helps! :))
Answer:
During the test for any significant difference in the means for the three assembly methods, there is significant evidence to reject the claim of equal population means
Step-by-step explanation:
Let;
SS be sum of square

The possible number of seats that the manager can order is 260 and 270.
270 is nearest to 267.
The least number of seats the manager should order is 270
<h3>What is an expression?</h3>
An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Number of seats needed = 267
Seats are sold in groups of 10.
The least number of seats to order:
We need a multiple of 10 nearest to 267.
We have,
26 x 10 = 260
27 x 10 = 270
270 is nearest to 267.
Thus,
The least number of seats the manager should order is 270
