Answer:
The correct choice is C
Step-by-step explanation:
The given curve is described by the parametric equations:
Let us eliminate the parameter by making t the subject in the first equation and substitute into the second equation;
We substitute this into the second equation to get:
This is the equation of a parabola whose vertex is at (4,-2)
The correct choice is C
Boardgame+snacks=total weight
total weight<25
boardgame=4
snacks=weight per each time number=14 times n or 14n
4+14n<25
minus 4 both sides
14n<21
divide both sides by 14
n<1.5
we can't send 0.5 package so we round down
n<1
send less than 1 snack pack
A
The answer is b hope it helped
Answer:
60°
Step-by-step explanation:
Am equilateral triangle is a triangle that has all its sides and angles equal. Note that an equilateral triangle has 3 sides and angles.
Let the angles be a, b and c
The sum of angle in a triangle is 180°, hence;
a+b+c = 180°
Since a = b = c
The equation becomes;
a+a+a = 180°
3a = 180
a = 180/3
a = 60°
Hence the measure of the angles of an equilateral triangle is 60° for the three angles.
