Answer: k(0) = 4; k (2x - 7) = 2x -3
Step-by-step explanation:
If k(a) = a + 4
K(0) will be 0 + 4
K(0)= 4
Then, k (2x - 7) = 2x -7 +4
K (2x - 7) = 2x - 3
The seats in the classroom form a square pattern
of four columns and six rows.
There is one of these mystery objects in every seat
between the hours of 9:00 AM and 12:00 Noon,
and also between the hours of 1:00 PM and 4:30 PM.
a). How many objects are there in seats at 12:45 PM ?
b). How many objects are there in seats at 2:07 PM ?
c). What do you think the mystery objects are ?
Answer:
sin(θ)^2 + tan2θ + sin(θ)^2 + cosθsinθ - cos(θ)^2. sinθ.tan2θ - cos(θ)^2 . sinθ - cos(θ)^2 / cosθsinθ
Answer:
Step-by-step explanation:
4x+2y = -24 -------------(i)
<u> -4x+y = 12 -</u>------------(ii)
add (i) &(ii) 3y = -12
y = -12/3
y = -4
Put y = (-4) in (i)
4x + 2*(-4) = -24
4x - 8 = -24
4x = -24 + 8
4x = -16
x = -16/4
x = -4
Answer: C, 420
Step-by-step explanation:
The first positive even numbers are from 2 to 40, so the sum is equal to the number of terms, times the number of terms plus one (20*21 = 420)
the sum is 420
