In a right triangle, this formula can be used:
a^2 + b^2 = c^2
when a and b are the legs and c is the hypotenuse.
Substitute the numbers from the problem into the formula.
14^2 + b^2 = 18^2
Simplify.
196 + b^2 = 324
b^2 = 128
b = square root of 128 = 11.3137...
When 11.313 is rounded to the nearest tenth, it is 11.3
The length of the other leg is 11.3 centimeters.
Hope this helps!
Answer:
9 & 2.
Step-by-step explanation:
let x represent the unknown numbers.
x + x-7 = 11
2x = 11+7
2x = 18.
divide both sides by 2.
x = 9.
x-7 = 9-7 = 2
Answers
Part 1: 210
Part 2: 24
Explanation
Part 1
This is called combination.
ⁿCm means, the number of different combinations of m objects out of n objects.
¹⁰C₆ = 10!/10!(10-6)!
= 10!/(6!×4!)
=210
Part 2
This is called permutation.
If you have nPm, this means the number of permutations of m objects out of n.
It's solve as follows;
nPm = n!/(n-m)!
⁴P₃ =4!/(4-3)!
= 4!/1!
= 24
Answer:
Y=1.88x
Step-by-step explanation:
x1=2 x2=3, y1=3.76 y2=5.64
(2, 3.76) (3, 5.64)
m(slope) =5.64-3.76/3-2
m=1.88
y-3.76=1.88(x-2)
y-3.76=1.88x-3.76
Y=1.88x
