Answer:

Step-by-step explanation:
<u>Step 1:-</u>
Given f(x) = 4 x+1 and g(x) =x^2-5

Given



Therefore 
Answer:
<u>The smaller angle measures 44° and the larger measures 136°</u>
Step-by-step explanation:
Smaller angle = x
Larger angle = 3x + 4
Therefore, we have:
x + 3x + 4 = 180
4x = 180 - 4
4x = 176
x = 176/4
x = 44 ⇒ 3x + 4 = 136
The smaller angle measures 44° and the larger measures 136°

"T<u>he function is decreasing":</u>
This means the slope of the function will be negative at the given point. Anywhere the line is going down, from left to right, is decreasing. This eliminates choices A and C.
<u>"The function is concave down":</u>
This means the curve of the function will be open down (think of an upside down u). This eliminates choice E.
<u>"f(x)>0":</u>
This is anywhere the curve is above the x axis. This eliminates choice D.
The answer is Choice B) x=2.
Hope this helps!!
ANSWER.
The correct answer is Option A
EXPLANATION.
The real number

to 9 decimal places.
You can see that the decimals are not repeating, neither will they terminate.
Therefore the real number
is irrational because, the decimal does not terminate or repeat
Also note that,
.
That is,
is a product of two irrational numbers, which still gives an irrational number.
