Answer:
(0, 2) and (1, 1)
Step-by-step explanation:
When x=0, the exponential term is 1, so the value of the function is the multiplier, 2. Thus (0, 2) is a point on the graph.
When x=1, the value of y is half of 2, so (1, 1) is also on the graph.
__
For x > 1, y < 1, so (2, 2.25) cannot be on the graph.
f(x) cannot be negative, so (-2, -8) and (-1, -1) cannot be on the graph.
The correct numbers are a. c. e. and f. The rest are incorrect. Hope this helped
Is there more? Because there isn't a question in this. :)
Answer:
Step-by-step explanation:
The original price of the wind chimes at the home improvement store is $w.
A customer signed up for a free membership card and received a 5% discount off the price. The value of the discount is
5/100 × w = 0.05w
The discounted price would be
w - 0.05w = 0.95w
Sales tax of 6% was applied after the discount. The amount of sales tax applied would be
6/100 × 0.95w = 0.057w
The algebraic expression to represent the final price of the wind chime is
0.95w + 0.057w
= 1.007w
Answer:
24 square kilometers
Step-by-step explanation:
Well, this is a trapezoid. The formula for the area of a trapezoid is 1/2 the height times base one plus base two. In other words, 1/2 <em>h </em>x (base 1 + base 2)
So in this case, the two bases are 4 and 12. So we would add the two bases to get 16. Now, we have to half the height. 3 divided by 1/2 is 1.5. So we then do the last step which is multiplying the height by the two bases. So in other words, 1.5 times 16. And 1.5 times 16 is 24. Therefore, the answer is 24 sqaure kilometers.
