Answer:
x = 10°
y = 14
Step-by-step explanation:
Angle A = angle B = angle C = 6x ( equilateral triangle has equal angles )
therefore
Angle A + Angle B + angle C = 180° ( sum of angle in a triangle)
6x + 6x + 6x = 180
18x = 180°
divide both sides by 18
x = 10°
to get y
side AC = AB = BC ( equilateral triangle has equal sides )
Y=2x²-x+4
1) we have to find the slope of this line.
we have to calculate the first derivative of this function.
y´=4x-1
The slope in x=3 will be: m(3)=4(3)-1=12-1=11.
2)We have to find a point of this line:
if x=3; ⇒y=2(3)²-3+4=18-3+4=19; Our point will be (3,19)
2) point-slope form: we need a point (x₀,y₀) and the slope.
y-y₀=m(x-x₀)
We know the slope (m=11) and the point (3,19); therefore:
y-19=11(x-3)
y=11x-33+19
y=11x-14
Answer: A. y=11x-14
Answer:
a. 2/3 or 0.6666...
b. AB = 6cm and AD = 3cm
Step-by-step explanation:
28/42 = 2/3
14/21 = 2/3
42*1/7 = 6
21*1/7 = 3
Answer:
<h2>No</h2>
Step-by-step explanation:
A function is a relation between sets that associates to every element of a first set exactly one element of the second set.
Each element from the first set is assigned exactly one element from the second set.
It's not a function, because for 0 are assigned two elements 1 and 3.
