Answer:
the first option
Step-by-step explanation:
Start by substituting 15 for x. Then, simplify to get f(15)=36.
cuz
f(x)=2(x+3)
f(15)=2(15+3)
= 2×18=36
gimme brainliest plz
Step-by-step explanation:
The point (12, 5)
x = 12, y = 5
=> r =√12²+5² =√144+25= √169=13
so, cos θ = x/r = 12/13 and
cot θ = x/y = 12/5
Answer:
Largest prime factor of the given expression is <em>379.</em>
Step-by-step explanation:
Given the expression:
To find:
The largest prime factor of the given expression.
Solution:
First of all, let us factorize the given expression.
Let us learn two formula:
Applying the above formula in the expression written above:
...... (1)
Similarly:
........ (2)
Multiplying the expressions from (1) and (2) to get the result:
So, largest prime factor of the given expression is <em>379.</em>
The answer is; five pieces of wood.

Answer:
(c) The t-distribution is bell shaped
(e) The t-distribution has more values at the extremes than a standard normal distribution
(f) The t-distribution is centered at 0
Step-by-step explanation:
When the sample size is small or population variance is unknown, and we have to estimate population parameter then t- probability distribution is used.
The t-distribution has properties as follows:
- The mean of t-distribution is 0. Thus, option (f) is correct.
- t-distribution is normal. Thus, option (c) is correct.
- As compare to standard normal distribution, t-distribution has more values at the extremes. Thus, option (e) is correct.
