Answer:
car help
Step-by-step explanation:
In order to determine which type of house insurance would be considered as cheapest first it is necessary to determine either monthly or either weekly
As we know that
Generally in the month there is a 4 weeks
So For Car Help, the monthly would be
= $8.60 × 4
= $34.40
And for Car safety, the quoted price is $36.10 per week
So according to the above calculation the car help would be choose as the cheapest
A function is a mapping from a set A to a set B, If, for all a1,a2 in A, where a1=a2, a1 and a2 get mapped to the same b in B

Answer:
Step-by-step explanation:
The tangent of the angle can be found using the identity for the tangent of the difference of angles.
tan(α-β) = (tan(α) -tan(β))/(1 +tan(α)tan(β))
The tangent of the angle of each vector is the ratio of the j coefficient to the i coefficient.
tan(α) = -2/3
tan(β) = 4/7
tan(α-β) = (-2/3 -4/7)/(1 +(-2/3)(4/7))
= (-14-12)/(21 -8) = -26/13 = -2
Then the magnitude of the angle between the vectors is ...
arctan(2) ≈ 63.43°
The answer is 1 because that's the point on the graph where x meets 0, or (0, 1)
Answer:
Step-by-step explanation:
The sum of the angles in a triangle is 180 degrees. This means that
Angle A + Angle B + Angle C = 180 degrees
Looking at the triangle,
Angle A = (15x + 10) degrees
Angle B = (15x - 10) degrees
Angle C = (3x + 15) degrees
Therefore,
15x + 10 + 15x - 10 + 3x + 15 = 180
15x + 15x + 3x + 10 - 10 + 15 = 180
33x + 15 = 180
Subtracting 15 from the left hand side and the right hand side of the equation, it becomes
33x + 15 - 15 = 180 - 15
33x = 165
Dividing the left hand side and the right hand side of the equation by 33, it becomes
33x/33 = 165/33
x = 5
Angle A = 15 × 5 + 10 = 85 degrees
