Answer:
a.) -1 < x < 5
b.) x <= 1
Step-by-step explanation: Domain is the independent variable (x).
For both question a and b, make sure that the number under the square root does not end up being negative. And the denominator of the fractional number is not equal to zero when variable x is being substituted for any value.
a.) y = √ x + 1 /√ 25 − x^2
Domain : -1 < x < 5
That is the minimum value for x is 0 and the maximum value is 4
b. f(x) = (√ 1 − x ) ln x
Domain : x <= 1
That is, x is less than or equal to 1
The maximum value for x is 1. x can be
1, 0, -1, -2, -3, ..........
Answer:
Alright so the answer is B but I'll explain why because im nice ig.
Step-by-step explanation:
So lets do some calcumalations.
We'll use 1 as n and should get an output of 3 to check these formulas. Since 1 is the first term and 3 is the first term value makes sense alright.
So 9^1-1 is 0 and any number to the 0 power is 1 so that wont work.
3(4)^1-1 = 3(1); that's the answer
4^1-1 = 1, + 3 = 4 so that wont work either
I hope this helps ya have a great afternoon
Answer:
k+15
Step-by-step explanation:
The word "increased" indicates that there will be addition and the word "product" indicates there will be multiplication. Since it's asking for the product of 5 and 3, we can solve by multiplying those two numbers to get 15. Our variable k will then add 15. So, the final answer we get is: k+15
Answer:
yes that is correct
Step-by-step explanation:
make sure you use mulipy subrract and - only
A=pi r^2
The diameter of the circle is 15 so half the diameter is the radius which is 7.5
(3.14) 7.5^2
(3.14)56.25=176.625
V= area of the circle times the height
176.625x5.7= 1006.7625
