Answer:
r = 8%
Step-by-step explanation:
Given that,
Interest, I = $24
Principal, P = $1200
Time, t = 90 days = 90/360 = 1/4 years
We need to find the rate.
We know that,
The simple interest is given by :
Put all the values,
So, the rate is 8%.

Step-by-step explanation:
Recall that an expression that can be factored as (U+V)(U-V) using distributive property for multiplication of binomials, should render: (the factorization given above is that of a difference of squares. Then, the idea is to write the original expression :
as a difference of perfect squares. Let's examine each term and its numerical and variable form to find if they can be written as perfect squares:
a) the term therefore, if we assign the letter U to
, the first term becomes:
b) the term therefore, if we assign the letter V to
, this second term becomes:
With the above identification, our expression can now be factored as a difference of squares:
Answer:
Step-by-step explanation:
From the graph, we can conclude the following points:
1. Number of zeros = 4 ( As the graph intersects or touches the x axis at 4 points.)
2. Number of turning points are 6. ( As there are 3 minimums and 3 maximums)
3. Number of zeros with even powers are 3. ( As the graph touches the x axis at 3 points)
Among all the four options, only the first option fulfills all the above points.
The above function has 4 zeros at
The above function has 3 even zeros
Now, number of turning points for the above function is given as:
Turning points = Number zeros + Number of even zeros - 1 = 4 + 3 - 1 = 6
Therefore, the correct option is option 1.
