<span><u>Answer </u>
Common difference = -4.5
<u>Explanation. </u>
An arithmetic sequence is a sequence in which the next term is found by adding a constant to the current term. This constant is called the common difference.
If a, b, c, d, e, ….is an arithmetic sequence, then the common difference will be,
Common difference = b-a=c-b=d-c=e-d…..
Now the question above common difference is;
Common difference = (-22.5)-(-14)=-4.5

Answer:
B. P′ (−4, 0)
Step-by-step explanation:
You can look at the graph. The X-axis always goes first. SO -4 is first because it's on the x-axis. ANSWER= (-4, 0)
Answer:
The algebraic expression for y -2 if this is subtraction is "some number" minus 2
Step-by-step explanation:
Answer:
x=3 and x=-5
Step-by-step explanation:
To find the x intercepts set y =0 and solve for x
0 = x^2+2x-15
Factor
What two numbers multiply to -15 and add to 2
5*-3 = -15
5+-3 =2
0 = (x+5) (x-3)
Using the zero product property
x+5=0 x-3 =0
x=-5 x=3
Answer:
Step-by-step explanation:
Length of the Plastic Sheet= 96cm
Width of the plastic Sheet =70cm
If a square of side x is cut from each corner of the plastic sheet to form the box.
Length of the box=96-2x
Width of the box=70-2x
Height of the box =x
Volume of the box = LWH
Volume=(96-2x)(70-2x)x
The maximum volume of the box is obtained at the point where the derivative is zero.
Setting the derivative to 0.
Since we are looking for the minimum value of x,
