Answer:
you divide the top number by the bottom number
Step-by-step explanation:
2/5 = 0.4
Arc length: s = radius (central angle)
Here, 18 cm = (radius)(7pi/8)
Solving for the radius:
18 cm (18 cm)(8)
radius = --------------- = ------------------ = ? Please calculate this.
(7pi/8) 7pi
Step-by-step explanation:
let the cost of the item be y
for taxes
30%of y
30/100×y=3y/10
=0.3y
freight charges =65
total =520
0.3y+65=520
0.3y=520-65
0.3y=455
y=455/0.3
y=$1516.7
y≈$1517
Answer:
y³ - 3y² + 1/y+3
Step-by-step explanation:
y² - 9 = (y - 3) ( y + 3)
y-3/(y-3)(y+3) = 1/y+3
Answer:
OPTION A
Step-by-step explanation:
To find the table substitute the points on the given function and compare the values.
The given function is:
.
OPTION A:
(i) When x = -2
LHS = y = 6.
RHS = (-2)² + 2 = 4 + 2 = 6.
LHS = RHS
(ii) When x = -1
LHS = y = 3
RHS = (-1)² + 2 = 1 + 2 = 3.
LHS = RHS
(iii) When x = 0
LHS = y = 2
RHS = 0² + 2 = 2.
LHS = RHS
(iv) When x = 1
LHS = y = 3
RHS = (1)² + 2 = 1 + 2 = 3.
LHS = RHS
(v) When x = 2
LHS = y = 6
RHS = (2)² + 2 = 4 + 2 = 6
LHS = RHS
OPTION B:
(i) When x = -2
LHS = y = -2
RHS = (-2)² + 2 = 6
LHS
RHS
OPTION B is eliminated.
OPTION C:
(i) When x = -2
Using the same reason as OPTION B this option is eliminated as well.
So, OPTION A is the correct answer.
