Answer:
-x² + 8x - 7
Step-by-step explanation:
Step 1: Write expression
(7 - x)(x - 1)
Step 2: FOIL (First Outside Inside Last)
7x - 7 - x² + x
Step 3: Combine like terms
-x² + 8x - 7
Answers:
a) 1/6
b) 0
Step-by-step explanation:
a) this is the way i remember
on a 6 sided dice there are <em>6</em> outcomes. 5 is 1 of those outcomes. so its 1/<em>6</em>
b) there no 7 on a six sided dice so its impossible. impossible outcomes are represented as 0
Answer:
= 84/177100
Step-by-step explanation:
Here 9 mid sized
16 compact cars
selected = 6
= 84/177100
for 3 mid sized
3 compact cars
then
3Cx/9Cx
divide by 3 we get
Cx/3Cxtaking Cx coomon
it become Cx =1/3 hence the probability is 1/3
Suppose an object starts moving at u and gains an acceleration of a. After time t, it gets a speed v after travelling a distance of s.
a = (v - u) / t => v - u = at
v = u + at
s = ut + 1/2(v - u) t
s = ut + 1/2 (at) t
s = ut + 1/2 at2
s = ut + 1/2 at2
v2 = (u + at)2
v2 =u2 + 2uat + a2t2
v2 = u2 + 2a (ut + 1/2 at2)
v2 = u2 + 2as
v2 = u2 + 2as
