Answer:
-2/3
Step-by-step explanation:
2^a = 0.5 = 2^-1 ⇒ a = -1
5^b = 125 = 5^3 ⇒ b = 3
Then the expression a^b +b^a is ...
a^b +b^a = (-1)^3 +3^(-1) = -1 +1/3 = -2/3
Answer:
260°
Step-by-step explanation:
∠RPS +∠PSR +∠SRP= 180° (∠ sum of △PRS)
∠RPS +45° +60°= 180°
∠RPS +105°= 180°
∠RPS= 180° -105°
∠RPS= 75°
Let's focus on quadrilateral PQTU.
Sum of interior angles= (n -2) ×180°, where n is the number of sides
∠QPU
= ∠RPS +∠TPU
= 75° +25°
= 100°
Sum of interior angles= (4 -2) ×180°
m +n +p +100°= 2 ×180°
m +n +p +100°= 360°
m +n +p
= 360° -100°
= 260°
It is an odd-degree polynomial. Therefore...
As the coefficient is negative for x^9.
When x < 0 or x approaches negative infinity, y or f(x) will approach positive infinity.
When x approaches positive infinity, y or f(x) will approach negative infinity.
So it is the second and the third.
The equation would be r = 1/6*s - 1. Put 2=r, which would be 2 = 1/6*s - 1, add 1 to both sides, the equation would be 3 = 1/6*s, multiplying by 6 would make the equation 18 = 1*s, or s. Therefore, there are 18 strawberries.
