The answer to this question would be: <span>-$1,700
In this question, we can separate the account into positive/debit and negative/credit value. The positive/debit value should be:
Joaquin has $1,300 in the bank
He has $4,000 worth of investment
Total positive value = $1300 + $4000= $5300
The negative value should be
</span><span>$7,000 worth of credit card debt
</span>Total positive value =$7000
<span>
Then the net worth should be: $5300 - $7000= -$1700</span>
Answer: $358.8 to the nearest tenth
Step-by-step explanation:
Compound interest is calculated by Where: A = P(1 + r)t
Where P= 300, r= 12% = 0.12, t= 1.5 years
Slot in the figures
300 (1 + 0.12) 1.5
300 (1.12) 1.5
300x 1.12
336e1.12
A = $ 358.84
Answer:
The mean is 104 (Just add them all up)
The median is either 6 or 10 (its the number in the middle, sometimes there are two medians)
The mode is 15 (It shows up more than once)
The range is 13 (Take the smallest number and the highest number and subtract)
The polynomial function whose real zeros are in -1, 1, 3 and whose degree is 3 is ![x^3-3x^2-x+3=0](https://tex.z-dn.net/?f=x%5E3-3x%5E2-x%2B3%3D0)
Step-by-step explanation:
We need to find a polynomial function whose real zeros are in -1, 1, 3 and whose degree is 3.
If -1, 1 and 3 are real zeros, it can be written as:
x= -1, x= 1, and x = 3
or x+1=0, x-1=0 and x-3=0
Finding polynomial by multiply these factors:
![(x+1)(x-1)(x-3)=0\\(x+1)(x(x-3)-1(x-3))=0\\(x+1)(x^2-3x-x+3)=0\\(x+1)(x^2-4x+3)=0\\x(x^2-4x+3)+1(x^2-4x+3)=0\\x^3-4x^2+3x+x^2-4x+3=0\\Combining\,\,like\,\,terms:\\x^3-4x^2+x^2+3x-4x+3=0\\x^3-3x^2-x+3=0](https://tex.z-dn.net/?f=%28x%2B1%29%28x-1%29%28x-3%29%3D0%5C%5C%28x%2B1%29%28x%28x-3%29-1%28x-3%29%29%3D0%5C%5C%28x%2B1%29%28x%5E2-3x-x%2B3%29%3D0%5C%5C%28x%2B1%29%28x%5E2-4x%2B3%29%3D0%5C%5Cx%28x%5E2-4x%2B3%29%2B1%28x%5E2-4x%2B3%29%3D0%5C%5Cx%5E3-4x%5E2%2B3x%2Bx%5E2-4x%2B3%3D0%5C%5CCombining%5C%2C%5C%2Clike%5C%2C%5C%2Cterms%3A%5C%5Cx%5E3-4x%5E2%2Bx%5E2%2B3x-4x%2B3%3D0%5C%5Cx%5E3-3x%5E2-x%2B3%3D0)
So, The polynomial function whose real zeros are in -1, 1, 3 and whose degree is 3 is ![x^3-3x^2-x+3=0](https://tex.z-dn.net/?f=x%5E3-3x%5E2-x%2B3%3D0)
