Answer:a
Step-by-step explanation:did it
Answer:
9 days
Step-by-step explanation:
Given isabella saves a nickel a day.From this day onwards she kept on incresing the savings by doubling them.
Here it form's a geometric progression with first term(a) = 1 and common ratio (r) = 2
S(n) =
Given condition is S(n) >500
n ≥ 9
So it will take 9 days for her savings to be more than 500
The graph is crossing the x-axis at x = - 4 .
If you observe the graph it is touching x = -4 and turning away. When graph exhibit such a behavior we say that the multiplicity of the root is 2. This means the root x = -4 occurs two times. So the factors of the polynomial are x + 4 and x + 4
So the given polynomial can be expressed as (x+4)(x+4).
Thus, the correct answer is option A
<span>Given
situation
=> A piece of string is said to have a measurement of 25 and ½ inches long.
=> It will be cut in ¾
Question: How many pieces of string will there be?
Solutions:
=> 25 and ½ = 25. 50 inches long
=> ¾ = .75 inches long
Let’s start the division to get the answer that we need:
=> 25.5 / .75
=> 34, thus there will be 34 pieces of cut string which measures 0.75 inches
long.</span>
