Answer:
81.12 cm²
Step-by-step explanation:
The area for a semicircle can be figured with this formula: (πr²)/2. The triangle's area formula is bh/2.
(3.14 * 4²)/2 + (14 * 8)/2 <em>(Work the operations in parentheses first.)</em>
(3.14 * 16)/2 + 112/2
50.24/2 + 112/2 (<em>Divide 50.24 by 2. Do the same for 112.)</em>
25.12 + 56 (<em>Add 25.12 & 56.)</em>
81.12 cm²
The area of the figure is 81.12 cm².
Answer:
d. empty or null set is the answer
It'd be a lot easier to help you if you'd share the answer graphs.
Just so that you know:
<span>f(x) = log(x + 3) + 1 can be graphed as follows:
</span>
1. Graph y = log x. This function's domain is x>0. It begins in Quadrant IV and ends in Quadrant I. It intercepts the x-axis at (1,0).
2. Now move the entire graph 1 unit to the left. This gives you the graph of y = log (x+1).
3. Now translate this entire graph up 3 units. This gives you the graph of <span>f(x) = log(x + 3) + 1.</span>
You want to leave a 15% tip on a meal that cost $65.00.
First, convert the 15% to an actual number that can be used in a calculation. For percents,this is always done by simply dividing the percent (in this case 15%) by 100%.So, the conversational term "15%" becomes 15% / 100% = 0.15 in terms of a real mathematical number.
Second, you need to find out what 15% of your $65.00 meal cost is.This is always done by multiplying 0.15 by $65.00, or
0.15 x $65.00=$9.75.
So, the amount of tip you are going to leave is $9.75.
This makes the total cost of your meal (to write on your charge slip or other payment)
$65.00 + $9.75 = $74.75.
