For the first expression
15 + 2d
A possible word problem would be this:
A person saves $2 per day of money. Before he started saving, he had $15 dollars set aside. Look for the expression that expresses the total amount of money saved in terms of the number of days passed
The second expression is
200 - 2m
A possible word problem would be this:
The distance from school to the park is 200m. A kid riding a bike is traveling at a speed of 2m/s from the school to the park. Write an expression for the distance remaining between the park and the kid.<span />
Answer:
Step-by-step explanation:
Curvilinear relationship
A curvilinear relationship is a type of relationship in which there are two variables. As and when the value of one variable increases, so does the value of the other. This continues until a certain point, after which an increase in one variable decreases the value of the other.
Example:
The two variables are - Work pressure and work performance. As work pressure increases, work performance increases until a certain point. After a threshold, when work pressure exceeds, work performance drops. This results in a curvilinear relationship between the two variables.
Volume of a cone = (1/3) * Area of Base * height
144 * 3 / 9 = Area of Base
Area of the Base = 48
S
A
=
96
sq in.
Explanation:
V
=
s
3
64
=
s
3
find the cubic root of each side
3
√
64
=
s
4
=
s
so the side of the cube is 4 cu in.
The surface area of a cube is
S
A
=
n
A
where
S
A
is surface area,
n
is the number of faces, and
A
is the area of one face.
Te area of one face (
A
) is
s
2
so
A
=
16
n
=

S
A
=
