You do 9x27=243 then take 2x31=62 add 243+62=305 then take 305 and subtract it from 28 305-28=277
so if i did it right you should get n=277
Answer:
t = 2.64 or
Step-by-step explanation:
v(t) =
v(t) = -32t + C
when t = 0, the velocity is 12
12 = -32(0) + C
C = 12
v(t) = -32t + 12
now finding position
when t = 0, position is 80
80 = 0 + C, C = 80
now finding when position = 0
0 =
0 =
t = -1.89, 2.64
t>0, so t = 2.64
Answer:
All the lateral faces in a triangular pyramid are congruent.
Step-by-step explanation:
- A triangular pyramid is a pyramid that has a triangular-shaped base.
- It has equilateral triangles which are equilateral.
- The pyramid is also known as tetrahedron because the base is of triangular shape.
- There are four faces and a triangular base in a triangular pyramid.
- There are four vertices and six edges.
As you can see in the graph, the dot is at (-8, -8).
It tells you the translate(move) the figure 6 units up, but since we're just focusing on the dot, just move the dot 6 units up.
If you do this, only the y coordinate will change, meaning it will be (-8,-2)
Answer: (-8, -8) is the point in the original position
(-8, -2) is the point in the final figure
Probability of distinct 3-digits is 1/6.
Probability of both the first digit and the last digit are even numbers is 1/5.
<u>Step-by-step explanation</u>:
Given set of numbers {1,2,3,5,8,9} = 6
Total number of 3-digits can be formed = 654 = 120.
<u>Probability of the three-digit numbers with distinct digits</u> :
The number of 3-digit numbers with distinct digits = (654) / (321) = 20.
P(distinct 3-digits) = no. of distinct 3-digits / Total no.of 3-digits
⇒ 20/120
⇒ 1/6
<u>Probability that both the first digit and the last digit of the three-digit number are even numbers</u> :
The even numbers in the set are 2 and 8 = 2 possibilities.
The number of 3-digits with 1st and 3rd digit are even = (262) = 24.
P(1st and 3rd digits even)= no. of 1st and 3rd digit even/Total no. of 3-digits.
⇒ 24/120
⇒ 1/5
