Answer:
Step-by-step explanation:
Number words Nebi has typed = 250
t = Duration of typing = 3 minutes
Number of words typed in 3 minutes = 150
Rate of typing in 3 minutes
So the linear equation representing the situation would be
Where
w = Number of words
m = Number of minutes after starting the timer
Answer:
f(-1) = 3
Step-by-step explanation:
f(-1) means the value of y at x = -1.
So what's the value of y at x = 1?
First, focus on the graph and look at x = -1.
Next, see which y-value does graph pass through when x = -1.
Looks like the graph passes y = 3 when x = -1
Thus, f(-1) = 3
U have both a dog and a cat
let us check each equation one by one
1. y=4x
for (1,4)
lhs = rhs
for (2,16)
lhs ≠rhs
2. y=x⁴
for (1,4)
lhs≠rhs
3. y=4^x
for (1,4)
lhs =rhs
for (2,16)
lhs=rhs
so y=4^x is the correct choice
Answer:
20 ways
Step-by-step explanation:
Given that six musicians will play in a recital. Three will perform before intermission, and three will perform after intermission
Since A singing first and B second is different from B first and A second, here order matters. So permutation
But selecting 3 members from 6 for the period before intermission is combination.
Thus 3 players selected in 6C3 ways = 20 ways
Once these 3 players are selected other three are fixed.
Total number of ways of choose which three musicians
will play before intermission = combination = 6C3 *1 = 20 ways
