Answer:
- 1/64 (x+4)² (x-3) (x-4) = 0
Step-by-step explanation:
f(x) = a (x+4)²(x-3)(x-4) ... curve touch (-4,0) and not cross x axis
x=0 f(x) = -3
a (4)² * (-3) * (-4) = -3
a = - 1/64
- 1/64 (x+4)² (x-3) (x-4) = 0
<u><em>Answer:</em></u>
A. $4397.9
<u><em>Explanation:</em></u>
We are given that Kendra sold 200 shares and that the price per share was $22.1
<u>This means that:</u>
Total value = 200 * 22.1 = $4420
Now, we know that the broker charged 0.5% commission on the total value
<u>This means that:</u>
Broker's charge = 0.5% * 4420 = 0.005 * 4420 = $22.1
<u>Therefore,</u>
Kendra's return = Total value - broker's charge
Kendra's return = 4420 - 22.1 = $4397.9
Hope this helps :)
<u>Answer</u>
A) 7.3 in.
Explanation
The area of a triangle = 1/2 ×base length × height
In the question given, base length = height = x
Area = 27 in²
1/2 × x × x =27
1/2×x²=27
x² = 54
x = √54
= 7.3485 in²
Which number carry’s the s?
I am guessing that the correct form of equation
is:
f(x)
= 16,800(0.9)^x
where
x is the exponent of (0.9)
Since
we are looking for the original population and x stand sfor the number of years,
therefore x=0
substituting:
f(x) = 16,800(0.9)^0
Since (0.9)^0 would just be equal to 1. Therefore
the original population is
16,800.
Answer: B. 16,800
