Answer: First, suppose that A is a knight. then when he says "i am a knave" he would be lying, so you have a logical failure because knights can't lie.
if A is a knave and says "I am a Knave, but B isn’t" then he would be telling a truth in the first part.
now you have two paths to tink itm as A said a truth, he can't be a knave. but if you consider the whole sentence can be splitted in two sentences.
I am a Knave ----- wealready know that will be a truth.
but B isn’t----- and now, as the first sentence is true, this must be false, so the sum of both sentences is false.
so A is a knave and B is a knave.
Answer: Answer Bellow
Step-by-step explanation:The sum of all four angles of the quadrilateral is 360°. To find the fourth angle or the missing angle in a quadrilateral when the measurements of three angles of a quadrilateral are known, then subtract the three angles from 360° to calculate the missing angle.
(If the answer is correct I would appreciate brainiest)
Answer:
The equation of the line is y = 6x - 14
Step-by-step explanation:
To find the equation of this line, start by using the two points with the slope formula to find the slope.
m(slope) = (y2 - y1)/(x2 - x1)
m = (16 - 4)/(5 - 3)
m = 12/2
m = 6
Now that we have the slope, we can use that and either point in point-slope form to find the equation.
y - y1 = m(x - x1)
y - 4 = 6(x - 3)
y - 4 = 6x - 18
y = 6x - 14
Answer:
t= 0.8 hr or 48 min.
Step-by-step explanation:
Speed of Enrique= 6 mph
Half and hour late it means that after 1/2 hr.
Speed of Enrique brother = 8 mph
Lets take Enrique cover x distance in time t hr .
So
x = 6 t ------------ 1
Then his brother will cover x/2 distance in time (t-1/2) hr.
So
x/2 = 8 (t-1/2) -----------------2
Now from equation 1 and 2
6 t = 16 (t-1/2)
6 t = 16 t - 8
So t= 0.8 hr or 48 min.
It means that his brother will take 0.8 hr to cover half of distance cover by Enrique .
Answer:
The maximum height is:
The ball reaches the ground in 1.79 s.
Step-by-step explanation:
We need to take the derivative and equal to zero to find the time at the maximum height.
(1)
Now, we just need to put t(max) into equation (1) to find h(max)
If we want to get the time when the ball reaches the ground we just need to equal h(t) to zero.
Let's solve this quadratic equation.
We will get two solutions and we must choose the positive value.
t1 = 1.79 u
t2 = -0.10 u
Therefore, the ball reaches the ground in 1.79 u.
I hope it helps you!
