Given real numbers a,b > 1.

Mathematics
1 answer:
irina [24]3 years ago
8 0

Answer:

FALSE

Step-by-step explanation:

Recall that a function f(x) is of exponential order c, if there exists a constant M such that and a real r such that

|f(x)|\leq Me^{cx}\;(x\geq r)

Now, take a = 2.5 and b = 2

The functions

f(x)=(2.5)^x\;g(x)=2^x

are both exponential of order 1, since  

\lim_{x \to \infty}\frac{f(x)}{e^x}=\lim_{x \to \infty}\frac{g(x)}{e^x}=0

but a>b

Y varies directly with x. When x is 4 y is 8. Find y when x = 10.
grandymaker [24]

Step-by-step explanation:

y = 4 when x = 8 So, 4 = 8k

k = 1/2

y = (1/2)x

Therefore, when x = 10, y = (1/2)(10) = 5

What is equilibrium if autonomous expenditures are $2,000 and the mpe is 0. 5?
STALIN [3.7K]

The equilibrium level if autonomous expenditures are $2,000 and the mpe is 0. 5 is $4000.

<h3>How to calculate the equilibrium?</h3>

From the information given, the autonomous expenditures are $2,000 and the mpe is 0. 5.

Here, the equilibrium level will be:

= 2000/(1 - 0.5)

= 2000/0.5

= 4000

In conclusion, the correct option is $4000.

Find the missing term in the geometric sequence. 180,___,5
Elan Coil [88]

Answer:

30.

Step-by-step explanation:

first term = a

3r term = ar^2

So here ar^2/ a  = r^2

r^2 = 5/180 = 1/36

r = 1/6

So missing term = 180 * 1/6 = 30.
