Answer:
$280
Step-by-step explanation:
According to the problem, calculation of the given data are as follows:
Principal amount (P) = $1,000
Rate of interest (r) = 7%
Time period (t) = 4 years
Here we use simple interest formula to calculate interest after 4 years.
I = P × r × t
By putting the value, we get
I = $1,000 × 7% × 4
= $70 × 4
= $280
I would say its 3/4 because there was only one blue and all together there is 4 now and the probability of picking a purple should be 3 out of 4.
Answer:
With
So then the x intercept would be (0,-5). And finally we can graph the function as we can see in the figure attached.
Step-by-step explanation:
For this case we know the following function:
We can begin the zeros or the values where the function is 0 like this:
And solving for x we got:
Now we can rewrite the expression like this:
And we can find the position for the vertex at x with this formula:
With
And replacing we got:
And then with the coordinate of x for the vertex we can find the coordinate of y replacing the value of x obtained for the vertex.
Then we can find the intercept using the value of x=0 and replacing into the function we got:
So then the x intercept would be (0,-5). And finally we can graph the function as we can see in the figure attached.
Answer: 9.3 ×
Step-by-step explanation: To write a number in scientific notation, first write a decimal point in the number so that there is only one digit to the left of the decimal point.
In this case, we can write 93,000,000 as 9.3000000 and notice that there is only one digit to the left of the decimal point.
Next, we count the number of places the decimal point would need to move to get back to the original number which is 93,000,000.
Since we will need to move the decimal point seven places to the left, we have an exponent of positive 7. Our exponent will be positive because we need to move the decimal point seven places to the right. Now, we can write our number in scientific notation.
9.3 ×
