Answer:
1
Step-by-step explanation:
Start at -0.5 and go toward 0.5.
From -0.5 to zero, it's a distance of 0.5.
From zero to 0.5, it's also a distance of 0.5.
Add the two distances, 0.5 + 0.5 = 1.
The distance between -0.5 to 0.5 is 1.
Answer:
17.5
Step-by-step explanation:
The following data were obtained from the question:
Angle R = 105°
Side R = r
Side S = 15
Side T = 6
The value of r can be obtained by using cosine rule formula as shown below:
inding sides:
r² = s²+ t² – 2st cos(R)
r² = 15² + 6² – 2 × 15 × 6 × cos105°
r² = 225 + 36 – 180 × cos105°
r² = 261 + 46.587
r² = 307.587
Take the square root of both side
r = √307.587
r = 17.5
Therefore, the value of r is 17.5
Answer:
y-4=-3(x-1)
Step-by-step explanation:
Point slope formula=
y-y_1=m(x-x_1)
Underscores mean subscript

Step-by-step explanation:
9,2
Answer:
432
Step-by-step explanation:
We are given that a four digit number can be formed by using digits from 1 to 9.
Two digits equal to each other and other two digits are equal to each other .
We have to find number of four digit numbers can be formed using digits from 1 to 9.
Total digits =9
Number of ways to filled first place =9
Number of ways to filled second place =1 because two digits are same
Number of ways to fill the third place =8 because different from previous two digits
Number of ways to fill the fourth place =1 because remaining two digits are same
Total number of ways to make four digit number =
Because two digits out of 4 and remaining two digits are same select out of 4
Total number of ways in which four digit number can be formed=
