Answer:
No.
Step-by-step explanation: Assuming you mean x^3*x-7, these two equations do not produce the same line.
Answer:
k=9
Step-by-step explanation:
First find r=22/20=1.1
The sum of the first k terms formula is a1•(1-r^k)/(1-r)
a1=20 and the sum is 271.59
Now plug in these values in the formula and find k.
271.59=20(1-1.1^k)/(1-1.1)
When you simplify this equation, you will get k=ln(2.358)/ln(1.1)
k=9
Answer:
W = 1.4119
Step-by-step explanation:
Is means equals and of means multiply
W = 7% of 20.17
Change to decimal form
W = .07 * 20.17
W = 1.4119
Because this triangle is an isosceles, we know that angle M and angle L are equal (as shown by the diagram)
So, we make the two values equal
5y-19=56
Take 19 to the other side as a positive
5y=75
y is equal to 15
But, we aren't done yet as the question asks us to find the value of k
So, we do
5*15-19+56+K=180
112+K=180
Take 112 to the other side as a negative number
180-112 is 68
So, angle K is equal to 68 degrees
If the furniture store took 9% off you would subtract and get 38 if you do subtract 47-9=38.
