Answer:
x^4 -53x^2 +108x +160
Step-by-step explanation:
If <em>a</em> is a zero, then (<em>x-a</em>) is a factor. For the given zeros, the factors are ...
p(x) = (x +8)(x +1)(x -4)(x -5)
Multiplying these out gives the polynomial in standard form.
= (x^2 +9x +8)(x^2 -9x +20)
We note that these factors have a sum and difference with the same pair of values, x^2 and 9x. We can use the special form for the product of these to simplify our working out.
= (x^2 +9x)(x^2 -9x) +20(x^2 +9x) +8(x^2 -9x) +8(20)
= x^4 -81x^2 +20x^2 +180x +8x^2 -72x +160
p(x) = x^4 -53x^2 +108x +160
_____
The graph shows this polynomial has the required zeros.
Well, one advantage simply is that its a loan. If its a loan, you can pay little by little until its paid off. Not sure if this helps, but I hope it does.
Answer:
20 times
Step-by-step explanation:
The equation is...
9.5x+105=14.75x
105=5.25x
20=x
Answer:
(2.3 times 10^4) is less than (1.15 times 10^8). That means that every single one of these answer options is wrong. However, If the problem were how many times bigger is 1.15 x 10^8 than 2.3 x 10^4 then the answer would be 5000. So therefore all of these answers are incorrect. I now understand why you are so desperate for this answer!
Step-by-step explanation:
Answer:
The required amount of interest is $5538.
Step-by-step explanation:
Given : $1,500 invested for 20 days at 6.75%, compounded daily.
To find : The amount of interest ?
Solution :
Applying compound interest formula,
Where, A is the amount
P is the principal P=$1500
r is the interest rate r=6.75%=0.0675 compounded daily
t is the time t=20 days
Substitute the value in the formula,
Therefore, The required amount of interest is $5538.
