Answer: D
Step-by-step explanation:
An irrational number plus a rational number results in an irrational number.
Answer:
C
Step-by-step explanation:
The table shows the sign of the function is the opposite of the sign of x, so ...
as x → ∞, f(x) → -∞; as x → -∞, f(x) → ∞ . . . . . matches the 3rd choice
This answer of this equation is n=10
Answer:
Step-by-step explanation:
I used 3 of the coordinates to solve for the a, b, and c that we need in
We have 3 unknowns so we need 3 equations. The coordinates I used are from your table:
(-2, 12), (-1, 6), (0, 2). Start with (0, 2). Sub in a 2 for y and a 0 for x in the standard form of the quadratic:
which simplifies very nicely to
c = 2. We will use that value now when we do this again using (-2, 12):
and
12 = 4a - 2b + 2 and
4a - 2b = 10 (1)
Do it again with the third coordinate (-1, 6):
and
6 = 1a - b + 2 and
a - b = 4 (2)
Now we have a system of equations, (1) and (2) that we will combine and solve for a:
4a - 2b = 10
a - b = 4
Multiply the second equation by -2 to get a new system:
4a - 2b = 10
-2a + 2b = -8
Add to get
2a = 2 so
a = 1
Now sub in 1 for a in (2):
1 - b = 4 and
-b = 3 so
b = -3
Now we have all that we need to write the equation:
The value of the given expression is 7.0 × 10⁸
<h3>Simplifying an expression</h3>
From the question, we are to determine the value of the given expression
The given expression is
(3.5x10⁶)÷(5x10-³)
The expression can be simplified as follows
(3.5x10⁶)÷(5x10⁻³)
= (3.5 ÷ 5) × (10⁶ ÷ 10⁻³)
= (0.7) × (10⁶⁻⁽⁻³⁾)
= 0.7 × (10⁶⁺³)
= 0.7 × (10⁹)
= 7.0 × 10⁸
Hence, the value of the given expression is 7.0 × 10⁸
