In general, when you state "the difference between a point A and a point B" meaning that you have to take the final value at the point B subtract the initial value at the point A"
<span>For example: Find the difference in distance between a point A =2 m and a point B = 5 m? </span>
<span>In this case: </span>
<span>In general: The difference in distance = 5 m - 2 m = 3 m </span>
<span>You can also write it as: </span>
<span>The difference in distance = 2 m - 5 m = -3 m </span>
<span>Since the distance between 2 points CAN'T be a negative value, you've to take the absolute value of -3 m to get the positive answer of 3 m. </span>
<span>This based on a scalar quantity. </span>
<span>Unless you're working on a Vector problem in Physics. In this case, you must take the final point subtract the initial point since the motion not only describes the magnitude but also describes the direction of the motion as well. </span>
<span>Again, in this case, you can have the magnitude is always a POSITIVE number and the direction can be either POSITIVE or NEGATIVE depends on the direction that you chose as a positive. </span>
<span>Back to your question. "the difference between 15 and the product of 5 and y" </span>
<span>I would write this statement as 5y - 15 </span>
What you must do for this problem is to re-imagine the equation in "vertex form"
Vertex form:
where "h" shifts the graph to the right if "h" is positive" and to the left if "h" is negative. K shifts the graph up and down.
a=1
h=1
k=0
So, your final answer should be:
Answer:
A, 55, 55
B, 30, 30
E, 45, 90
Are the possible choices for the measures <A and <C. Hope this helps!
Answer:
Pat earnings = $181
Ally earnings = $362
Julie earnings = $452
Step-by-step explanation:
Let
Pat earnings = x
Ally earnings = 2x
Julie earnings = 2x + 90
Total earnings = $995
Total earnings = Pat earnings + Ally earnings + Julie earnings
995 = x + 2x + (2x + 90)
995 = 3x + 2x + 90
995 = 5x + 90
995 - 90 = 5x
905 = 5x
x = 905/5
x = 181
Pat earnings = x = $181
Ally earnings = 2x
= 2(181)
= $362
Julie earnings = 2x + 90
= 2(181) + 90
= 362 + 90
= $452
Answer:
Yes.
Step-by-step explanation:
A fourth degree function is defined as a function with a multiplicity of four. This can be done with any number distinct roots less than or equal to four. If the three distinct roots given must be the only roots, we can choose any of the roots to square and make the function a fourth degree polynomial. Otherwise, we can add another root to make a fourth degree polynomial. Either way, it's possible.
