I'd say it's x + 1 < 17.
Because the operator should be included as a person as well.
Answer: 150 degrees
Step-by-step explanation:
Answer: X = 42
Steps:
(3x + 12) + x = 180
3x + 12 + x = 180
4x + 12 = 180
4x = 180 - 12
4x = 168
x = 168/4
x = 42
Check:
(3x + 12) + x = 180
3x + 12 + x = 180
3(42) + 12 + 42 = 180
126 + 12 + 42 = 180
180 = 180 ✅
I would appreciate the brainliest if this was correct and had helpful & clear steps! :)
F ( x ) = 3 sim x + 3 cos x
f ` ( x ) = 3 cos x - 3 sin x
f `` ( x ) = - 3 sin x - 3 cos x = - 3 ( sin x + cos x )
The inflection points:
- 3 ( sin x + cos x ) = 0
sin x + cos x = 0
sin x = - cos x / : cos x
tan x = - 1
x 1 = 3π / 4
x 2 = 7π / 4
The function is concave up when f``(x) > 0
- 3( sin x+ cos x ) > 0
sin x + cos x < 0
tan x < - 1
f is concave up for:
x ∈ ( π/2, 3π/4 ) ∪ ( 3π/2, 7π/4)
f is concave down for:
x ∈ ( 0, π/2 ) ∪ ( 3π / 4, 3π/2 ) ∪ ( 7π / 4, 2 π ).
Product factor is an expression in where you multiply the same value digit many times.
Exponent is the expression in where you convert product factor expression into a shorter expression
For example of product factor:
=> 9 x 9 x 9 x 9 x 9 x 9 x 9 x 9 x 9
As you can see, 9 is multiplied many times, that makes it longer.
Now, let’s make this product factor shorter using exponent.
=> since 9 is multiplied 9 times the exponent expression is:
=> 9 9 in where 9 is the base and the other 9 is called exponent.
