Answer:
Please check explanations
Step-by-step explanation:
Given the factored form, all we have to do is to equate each of the factor to zero, then solve for x
The particular value of x represents the solution that shows the value of the x-intercept
for example
In a case of a quadratic equation where we have
(x-a)(x-b) = 0
Then we can have
(x-a) = 0 or ((x-b) = 0
Then we have x = a or x = b
a and b are the x intercepts in this case
Answer:
The measure of JK is 60
Step-by-step explanation:
It is given that the points F, G, and H are the midpoints of the sides of triangle JKL , FG = 37, KL = 48, and GH = 30.
The point F is midpoint of JK, point G is midpoint of KL and the point H is midpoint of LJ as shown in figure .
According to the midpoint theorem, the line connecting the midpoints of two sides is parallel to the third and its length is half of the third si
Answer:
it will be the first one
Step-by-step explanation:
There are 720 ways through which 3 numbers can be selected from 10 numbers to open a keypad lock.
Given that there are 10 numbers are 3 numbers are required to open a keypad lock.
Permutations are the number of ways in which objects can be selected without replacements to form subsets.
It is expressed as n
=n!/(n-r)!.
Factorial of a number is the product of consecutive numbers less than the number.
Total numbers available=10
Numbers to be selected=3
Number of ways can be found by using permutations.
Number of ways =10
=10!/(10-3)!
=10!/7!
=10*9*8*7!/7!
=10*9*8
=720 ways.
Hence there are 720 ways through which 3 numbers can be selected from 10 numbers.
