1,1 is your answer. just apply the rule to the set points
Answer:
<u>a(n)=80*(9/10)^(n-1)</u>
Step-by-step explanation:
I think u r confused
this sequence is geometric not arithmetic
HOw we know that ??
when we get a common difference <u>that must Be equal </u>
d=72-80=-8 not equal to d=64.8-72=-7.2
So it is not arithmetic
but when we get the common ratio that also must <u>be equal </u>
r=72/80=9/10 equal to r=64.8/72=9/10
So it is geometric
By using this equation:
a(n)=a*r^(n-1)
and we have <u>a=80 , r=9/10</u>
Then <u>a(n)=80*(9/10)^(n-1)</u>
<em>I really hope this helps <3</em>
Answer:
Step 4
part a: no answer yet still having trouble showing my work
part b:
-0.125(x-24)^2+50
-0.125(x-24)(x-24)+50
-0.125(x^2-24x-24x+576)+50
-0.125(x^2-48x+576)+50
-0.125x^2+6x-75+50
-0.125x^2+6x-22
a=-0.125
b=6
c=-22
part c: yes he went through
part d:
plug in roots (4,0) and (44,0)
if x is 4 and y is 0
0=-0.125(4)^2+6(4)-22
0=-2+24-22
0=-2+2
0=0
if x=44 and y=0
0=-0.125(44)^2+6(44)-22
0=-242+264-22
0=-242+242
0=0
Answer:
a. 800 grams = 1.76 pounds
b. 700 grams = 1.54 pounds
Step-by-step explanation:
Here is a weight conversion problem.
In this question, we shall be making conversions from grams to pounds.
Kindly note that 453.592 grams = 1 pound as stated in the question
a. 800 grams
Kindly recall;
453.592 grams = 1 pound
800 grams = x pound
Thus;
453.592 * x = 800 * 1
x = 800/453.592
x = 1.764 pounds which is 1.76 pounds to 2 decimal places
b. 700 grams
1 pound = 453.592 grams
y pound = 700 grams
y * 453.592 = 700 * 1
y = 700/453.592
y = 1.543 pounds which is 1.54 to 2 decimal places
