Answer:
the first option
Step-by-step explanation:
it is directly there in the problem description.
f(x) = 1.8x - 10
g(x) = -4
so, for f(x)=g(x) that automatically means
1.8x - 10 = -4
1.8x = 6
x = 6/1.8 = (6/1) / (18/10) = 10×6 / 18×1 = 60/18 = 10/3
Answer:
Step-by-step explanation:
20
Answer:
sin(B) = 12/13
cos(B) = 5/13
tan(B) = 12/5
csc(B) = 13/12
sec(B) = 13/5
cot(B) = 5/12
Step-by-step explanation:
If ABC is a right triangle, assuming that ∠C = 90°, then the segment AB =13 is the hypotenuse and the other two sides are:
The six trigonometric functions of angle B are:
Answer:
Effective tax rate of Maria is 5.08%.
Step-by-step explanation:
Effective tax rate ETR =
As a percent we can represent ETR = ×100
In this question Maria has a total tax = $3072 and gross income = $60449
By putting these values in the formula ETR = ×100 = 5.08
Therefore her effective tax rate is 5.08%.
Answer:
20a (less than or equal to) 28a
Step-by-step explanation:
PEMDAS
2a + 3= 5a
4*5a=20a
2. a+1=1a
-3*1a=-3a
-3a+31= 28a
