2. Because it is being reflected across the X axis, the X coordinate would change signs, but the Y coordinate would remain the same sign.
A(-6,-4) would become A'(6,-4)
B(-3,5) would become B'(3,5)
C(1,-1) would become C'(-1,-1)
The answer would be the third choice.
3. Reflected across the Y axis, the X would stay the same sign and the Y would change signs.
P(-2,-4) would become P'(-2,4)
Q(2,-5) would become Q'(2,5)
R(-1,-8) would become R'(-1,8)
The answer would be the second choice.
Answer:
A. Domain: {-8, -6, -4, -2, 0} Range: {2}
Step-by-step explanation:
The domain of a function is the x values, the range is the y values. you order them in either greatest to least or least to greatest (keep this consistent in both domain and range values). also, if a value repeats, only list it once (this is why the range is {2} rather than {2, 2, 2, 2, 2} )
You would need 88 boxes. dividing 962 by 11 would lead to 87.45, but the remains cannot just be left out therefore you’d need 88 boxes
The formula for the area of a circle is pi times the radius squared. Here are the steps to solving this problem.
1. First, find the radius. Since the radius is allows half of the diameter, then we divide the diameter by two. 50/2= 25
2. Next, we square the radius. 25^2= 625
3. After that we multiply 625 ft by pi(3.14).
625 times 3.14= 1962.5
4. The last step is to round the the answer to the nearest square foot. Since 5 is at the end, we round up to 1,963.
So the answer is 1,963 ft^2.
Answer:
Two
Step-by-step explanation:
The table is saying that, if Sandra swam enough races, she should expect to get 20 firsts, 12 seconds, 6 thirds, and two no placements.
Her expected value of points will be the average (mean) of all the points awarded for each race.
The average is the total number of points divided by the number of races.
The simulation says that, if she swam 40 races, she should expect to earn a total of 90 points.
She can't win a fraction of a point, so she can expect to win two points in her first race.
