The perimeter of the triangle ΔADE will be 30 units.
Let the triangle be ABC.
Then the perimeter of the triangle will be
Perimeter = AB + BC + CA
AC and BD are perpendicular bisectors of each other.
The diagram is shown below.
P = AD + DE + EA
P = 13 + 12 + 5
P = 30 units

THE CORRECT ANSWER IS 30.
AC and BD are perpendicular bisectors of each other.
=> ABCD is rhombus.
AD = 13
AE = √(13^2 - 12^2) = 5
Answer:
5
Step-by-step explanation:
To find the x-intercept of the line 4x+11y=20, we need to set y=0 and solve for x. This is because the x-intercept is the point where the line crosses the x-axis, which is the point where y=0.
First, substitute y=0 into the equation: 4x+11(0)=20
Simplify: 4x=20
Solve for x: x=5
Therefore, the x-intercept of the line 4x+11y=20 is 5.
ANSWER
Find out the how many milliliters of water did coach Kelly put in each cooler.
To proof
let us assume that the water put in the each cooler be x.
As given
Coach Kelly bought 32 L of water
she divied the water equally between 8 coolers
1 litre = 1000 miilitre
solving the above
x = 4000 millitre
therefore 4000 milliliters of water did coach Kelly put in each cooler.
Hence proved
Answer:
Option D is correct
Step-by-step explanation:
Option D is correct
Being an arithmetic sequence there will be common difference between the consecutive terms
Option A is incorrect because it is not necessary that explicit formula is an arithmetic sequence we can create explicit formula for any sequence
Option B is incorrect because recursive formula can be created for any sequence for geometric series also.
Option C is incorrect because the sequence that has constant ratio is the geometric sequence not an arithmetic sequence.
Answer:
D. She showed that f(n) - f(n - 1) was a constant difference.
Step-by-step explanation:
∵ A sequence is called arithmetic if there is constant difference between consecutive numbers,
Thus, option D is correct.
In Explicit formulas, we define each term in a sequence directly,
Thus, there are many sequences other than arithmetic that have explicit formula,
i.e. Option A can not be true.
Now, recursive formula defines the relation between successive terms,
Thus, there are many sequences other than arithmetic that have recursive formula,
i.e. Option B can not be true.
Also, if the ratio between successive terms is constant then the sequence is a Geometric sequence,
A GP can not be an AP,
i.e. Option D can not be true.
