Answer:
21 N
Step-by-step explanation:
let mass be m and weight be w
Given w varies directly with m then the equation relating them is
w = km ← k is the constant of variation
To find k use the condition m = 7 , w = 49 , then
49 = 7k ( divide both sides by 7 )
7 = k
w = 7m ← equation of variation
When m = 3 , then
w = 7 × 3 = 21 N
It's division.
Hope I helped!
1 US = 1.09 Australian
divide by 1.09 on both sides to find how much a 1 Australian dollar is worth.
1/1.09 = 1 Australian dollar
1 Australian dollar = 0.92 US dollar
mulitply 35 on both sides of the equation
35 Australian = 35 (0.92) = 32.2 US dollars
Answer:
(6,-34)
Step-by-step explanation:
You can use the vertex formula to find the x of the vertex and then plugin the x value into the formula to find the y value.
Now plugin 6 into y=x²-12x+2
y=x²-12x+2
y=6²-12(6)+2
y=36-72+2
y=36-72+2
y = -34
Vertex = (6,-34)
Answer:
20
Step-by-step explanation:
The area can be calculated by Length times width. The length is 10 and the width is 2 so 10 x 2 = 20
