In total Lt. Bartlett spent 4.5 hours exercising. He spent a total of 1 hour sprinting so you would divide 1 by 4.5 to get .222 repeated hours which could be rounded to .22 I hope this helps, I’m not the best at explaining things.
<A+<B+<C=180(sum of triangle)
55+65+<C=180
120+<C=180
<C=60
<u>Answer</u>
x ≥ -2
<u>Explanation</u>
The inequalities are solve the same way as algebra. This would be solve as follows.
-2x-1≤5
-2x≤5+1
-2x≤4
Divide both sides of the inequality by -2. This will change the sign from ≤ to ≥.
(-2x)/(-2) ≤ 4/(-2)
x ≥ -2
Answer:
See below
Step-by-step explanation:
<u>Given points:</u>
- A (3, -1)
, B (9, 2)
, C (6, -4)
First, plot the points on the coordinate plane (see attached)
<u>We see that AB and BC look the same. Let's find their length:</u>
- AB =
- BC =
We showed that AB = BC = 3√5, so the triangle has two sided of the same length, therefore is isosceles.
Answer:
Definition:
The Jacobian of the transformation x = f(r, θ) and y = g(r ,θ) is:
= ......[1]
Given: and
then,
and
Substitute these value in [1] ;
=
=
On simplify:
=
[ Use ]
therefore, the jacobian transformation of and is;
