Answer:
2x⁴ - 11x³ + 7x² + 5x - 3
Step-by-step explanation:
(2x²-3x+1) * (x²-4x-3) = 2x⁴ - 8x³ - 6x² - 3x³ + 12x² + 9x + x² - 4x -3
= 2x⁴ - 11x³ + 7x² + 5x - 3
Answer:
2 days
Step-by-step explanation:
For the flight to and from it will cost a total of $998
We subtract the flight from the budget, which leaves us with $285
Next, we subtract 1 day from $285 which is $112
That leaves us with $173.
We then subtract one mire day ($112) which leaves us with $61
Answer:
y = 8
x = 8√5
z = 4√5
Step-by-step explanation:
Using the formula (which is a geometric mean):
a y
---- = -----
x a
Where a is the altitude (y), x is a projection (16), and y is the other projection (4):
y 4
---- = -----
16 y
Cross multiply:
y² = 16 (4)
y² = 64
√y² = √64
y = 8
To find x and z, use the Pythagorean Theorem:
16² + y² = x²
256 + 8² = x²
256 + 64 = x²
320 = x²
√320 = √x²
√64√5 = √x²
8√5 = x
x = 8√5
4² + y² = z²
16 + 64 = z²
80 = z²
√80 = √z²
√16√5 = √z²
4√5 = z
z = 4√5
Answer:
ASA
Step-by-step explanation:
With this inverse functiion, you would want to replace f(x) with y for now.
so new equation
y = 1/4^x - 12
then change positions of y and x
x = 1/4^y - 12
Then try to get Y by itself
x + 12 = 1/4^y
So then use Logarithm
Log Base_ 1/4 _ (x+12) = y
