Answer:
Step-by-step explanation:
You don't say whether this is compound interest or simple interest.
I will assume it's compounding that interests you.
The appropriate formula is
A = P(1 + r)^t, where r is the interest rate as a decimal fraction, t is the time in years, and P is the original amount. Thus:
A = $1000·(1 + 0.05)^t, or A = $1000·(1.05)^t
Please note: There were apparently possible answer choices. Next time, please be sure to list such choices. Thank you.
3. Sqrt of 40
4. Sqrt of 148
Distance formula is sqrt of (x-x1)^2+(y-y1)^2
So (-4-2)^2+ (3-5)^2
(-6)^2+(-2)^2
36+4
Sqrt of 40
Do the same process for 4!
Ps don’t forget to keep the square root
Answer:
The answer to your question
a) Values excluded = -2, 0
b) solutions = -2/3, 2
Step-by-step explanation:
Equation
a) x is restricted when the denominators equal zero, so let's get them.
2x + 4 = 0 2x = 0
2x = - 4 x = 0 / 2
x = -4 / 2 x = 0
x = -2
x must be different to -2, 0
b)
4x² = (x + 2)²
4x² = x² + 4x + 4
4x² - x² - 4x - 4 = 0
3x² - 4x - 4 = 0
3x² - 6x + 2x - 4 = 0
3x(x - 2) + 2(x - 2) = 0
(x - 2)(3x + 2) = 0
x₁ - 2 = 0 3x₂ + 2 = 0
x₁ = 2 x₂ = -2/3
Answer:
Jacket A costs 43$
Jacket B costs 55$
Step-by-step explanation:
According to the Question,
- Given, Two jackets have a combined cost of $98. Jacket 'A' costs $12 less than jacket 'B'. Thus, if the jacket B Cost 'X' So, Jacket A costs 'X-12'.
Therefore, Jacket A + Jacket B = 98
X-12+X = 98
2X = 110
X = $55 ( Cost of jacket B) & Cost of Jacket A is 55-12 = 43$ .
