Answer:
U'(3,4)
J'(0,4)
B'(4,3)
P'(3,1)
Step-by-step explanation:
Refection over y-axis:
After reflection across y-axis, the sign of the x-coordinate will change.
(x ,y) after reflection will be (-x ,y)
U(-3, 4) → U'(3 ,4)
J(0,4) → J'(0,4)
B(-4,3) → B'(4,3)
P(-3, 1) → P'(3 ,1)
To find the common ratio in a geometric sequence, u divide the second term by the first term. 20/80 = 1/4 <== common ratio
Terms are found in a geometric sequence by multiplying each number by the common ratio to get to the next number.
start with 80
80 * 1/4 = 80/4 = 20
20 * 1/4 = 20/4 = 5
5 * 1/4 = 5/4
5/4 * 1/4 = 5/16 <===
5/16 * 1/4 = 5/64 <===
5/64 * 1/4 = 5/256 <===
Remember to be mindful of signs when adding and subtracting. 2c^2+5c+4
Step-by-step explanation:
f(x) = y= -x²-x+6
When y is max, f'(x) = 0
f'(x) = -2x-1
Equating to 0,
-2x-1= 0
x= -1/2
Put the value of x in f(x)
y = -(-1/2)² -(-1/2) +6
= -1/4+1/2+6
= 6+1/2
y= 13/2
