Answer:
JL = 9√13
Step-by-step explanation:
All of the triangles in this geometry are similar:
∆MKL ~ ∆MLJ ~ ∆LKJ
Corresponding sides of similar triangles are proportional, so you can write the relations ...
JL/JM = JK/JL ⇒ JL² = JM·JK
LM/JM = KM/LM ⇒ LM² = JM·KM
Using the second expression to find JM, we have ...
JM = LM²/KM = 18²/12 = 27
We know that JK = JM +KM. Then the first expression can be ...
JL² = 27·(27 +12) = 9²·13
JL = 9√13
-3 because 4 times -3 = -12 -7=-19
Answer:
you can split the garden in: 1/2 circles x 4 (because you have 4 half-circles) + a square.
the square's area is 4 x 4 = 16; the circles is pi x R x R (pi = aprox 3.14, R of the cirlce is 4m / 2 = 2m, because the square's side is 4m and is the same size with circle diagonale: Diag of circle = 2 X Radius => Radius = Diag / 2)
than answer will be: 16 + 3.14 x 2 x 2 x 2 (the last 2 is, because you have 4 halves of circles, than you will have 2 full circles) = 45.12, than answer is H, because 41 is the nearest number to 45.12
The inequality that represents the steps taken after the first day is 2000 + 500x ≥ 10000
<h3>Part A: The inequality that represents the number of steps?</h3>
The given parameters are:
- Initial number of steps = 2000
- Rate each day = 500
- Total number of steps = At least 10000
In inequality, at least means greater than or equal to i.e. ≥.
So, the inequality that represents the number of step each day (x) after the first day is:
2000 + 500 * x ≥ 10000
This gives
2000 + 500x ≥ 10000
<h3>Part B: How to exceed the goal</h3>
To exceed the goal faster, Angel can do any of the following activities:
- Increase the initial number of steps from 2000 to (say) 2500. This is represented by 2500 + 500x ≥ 10000
- Increase the rate from 500 to (say) 600. This is represented by 2000 + 600x ≥ 10000
