Answer:
y = 
Step-by-step explanation:
Let the equation of the exponential function is,
y = a(b)ˣ
Since the graph of this function passes through two points 
and (3, -1)
For the point ,
---------(1)
For second point (3, -1),
-1 = a(b)³ ---------(2)
Divide equation (2) by equation (1),
= 
From equation (2)
-1 = 
-1 = 
a = 8
Therefore, equation of the exponential function will be,
y =
Answer:
1436.8 cm^3
Step-by-step explanation:
You just plug it in:
r = 7 since it is the radius
Volume = (4 / 3) pi x r^3
Volume = (4 / 3) pi x (7)^3
Volume = 1436.75 = 1436.8 cm^3 (nearest tenth)
Answer:
A. 2^11
Step-by-step explanation:
(They are basically asking what's 2^4 × 2^7, but with more words.)
I usually do each exponent individually:
2^4 is the same as 2 × 2 × 2 × 2 = 16 (or you could have read the text to figure that out)
2^7 is the same as 2 × 2 × 2 × 2 × 2 × 2 × 2 = 128
Then just multiply 128 and 16 to get 2,048, and see which option also gives you 2,048.
BUT, you can also:
(Combine the exponents together to get your answer. Just remember that if it's multiplication you add them, and if it's division you subtract them.)
2^4 × 2^7
4 + 7 = 11
2^11 (This equals 2,048 btw. You don't even have to check all the options to get the answer).
Hope this helps friend :)
The last part I learned from another user, while answering one of your other questions. I personally find this mind blowing, lol.
I know for a fact that the Airjet Express had shorter flight times because it had lesser dots than the Cross Country Airlines. Hope this helped!
The complementary event is that a customer does not enter the store within one minute of closing, and the probability is 75%.
The complement is found by subtracting from 100%; 100-25 = 75%.
