We observe that we have a polynomial of the form:
ax2 + bx + c
Therefore, to complete the square, we must use the following formula:
a (x + (b / 2a)) ^ 2 + c - (b ^ 2 / 4a)
Thus,
Step 1:
We define:
a = 5
b = 15
c = -4
Step 2:
we use the formula:
5 (x + (15 / (2 * 5))) ^ 2 + (-4) - ((15) ^ 2 / (4 * 5))
5 (x + (15 / (2 * 5))) ^ 2 - 15.25
5 (x + 1.5) ^ 2 - 15.25
5 (x + 3/2) ^ 2 - 61/4
Answer:
Gio should do first:
a (x + (b / 2a)) ^ 2 + c - (b ^ 2 / 4a)
a = 5
b = 15
c = -4
300,000
the hundred thousands place is "2" and 28 is closer to 30
Answer:
I can't see the answers but i'm guessing it should be 1.1*3
Step-by-step explanation:
Since we need an angle measure we have to use an inverse trig ratio, sin^-1, cos^-1, or tan^-1.
Setting up the right triangle we have the opposite and adjacent so we use tan.
tan angle = 28/32
tan^-1 (28/32) = 41 degrees
Answer:
The geometric mean of given data is approximately 2.6051
Step-by-step explanation:
We are given the following data in the question:
1, 2, 3, 4, 5.
We have to find the geometric mean.
Formula:
Putting the values, we get,
Thus, the geometric mean of given data is approximately 2.6051
