F(x) = 2x² - 8x - 10.
This is a parabola open upward (since a>0) with an axis of symmetry = -b/2a:
a) axis of symmetry: x = -(-8)/(2*2) = 8/4 = 2. Then x = 2, which is the x component of the vertex
b) for x = 2, f(x) = f(2) = - 18 (component of y of the vertex)
c) VERTEX(2, - 18)
d) DISCRIMINENT: b² - 4.a.c = 64 - 4*2*(-10) = 144
Answer:
73%
Step-by-step explanation:
/ means divide
you divide the total by those who showed up
27/37 = .7297 = around .73 = 73%
Answer: 35.88
Step-by-step explanation: So if something is marked up by 8.7% it means, it is 108.7% of the original number.
So we can convert 108.7% to a decimal by dividing 108.7 by 100, which equals 1.087.
So if we want to find the original number, all we have to do is divide 39 by 1.087.
This will give us 35.88 as the original number rounded to the nearest tenth.
Answer:
<h2>6.5</h2>
Step-by-step explanation:
Given the sum of the series represented as . <u>To get the sum to infinity of the geometric series, we need to get its first term and its common ratio</u>. comparing to the general term of the sum of series of a GP
a = first term of the series
r = common ratio
On comparing to the given series, a = 1.3 and r = 0.8
Sum to infinity of a Geometric series is expressed as:
Hello!
So, according to the problem, the heart rate of a bear during hibernation is its original amount.
So we can write an equation to help us understand this.
of sr = 28
We can use inverse to make this easier to solve. 2 × 28 = sr.
So, in simple form, we multiply.
28 × 2 = 56
Our final answer would be:
A bears heart rate during the summer would be 56 beats per minutes.
