Answer:
#3
Step-by-step explanation:
from the formula given, the part "(1.025)" would be the growth factor or rate.
This part has a formula:
(1 + r)
where r is rate
So substituting, we get:
So, in pecentage, we have to multiply, thus we get:
0.025 * 100 = 2.5%
Answer choice #3
Answer:
B. 63
Step-by-step explanation:
There are two similar triangles given in the diagram above. Since they area similar, they also have corresponding side lengths that are proportional.
Therefore:
(6 + 3)/3 = x/21
9/3 = x/21
3 = x/21
Cross multiply
21*3 = x
63 = x
x = 63

<h2>Steps:</h2>
So for this, I will be completing the square to solve for x. Firstly, add 10 and subtract 30x on both sides of the equation:
Next, we want to make the left side of the equation a perfect square. To find the constant of this soon-to-be perfect square, divide the x coefficient by 2 and square the quotient. Once you get that result, add it to both sides of the equation:
Now, factor the left side:
Next, square root both sides:
Now, add 15 to both sides of the equation:
This is the <em>exact</em> solution. To find the approximate solution, solve the left side twice -- once with the plus sign, once with the minus sign:
<h2>Answer:</h2>
In short:
- Exact Solution:
- Approximate Solution (Rounded to the hundredths):
The only statement that is true is ...
The y-intercept of function f is greater than the y-intercept of function g.
_____
The y-intercept of function g cannot be greater than 4, since that parabola opens downard and the vertex is at y=4. Hence the 1st statement is false.
The minimum of function f is at (2.5, -0.25), hence the 2nd statement is false.
The vertex of function g is its maximum, hence the 4th statement is false.
