Answer:
The amount spent on the refrigerator is $ 800 .
Step-by-step explanation:
Given as :
The amount spent on television = $ 1600
Le The total amount in the account = $ A
so, The amount left in account after spent on television = $ A - $ 1600
The amount spent on refrigerator = × ( A - 1600 )
The amount left in his saving account = × A
Now, According to question
A - ( 1600 + × ( A - 1600 ) ) =
× A
Or, A - × A = 1600 +
× ( A - 1600 )
Or, × A = 1600 +
× A -
× 1600
or, × A -
× A = 1600 - 640
Or, × A = 960
or, × A = 960
∴ A =
I.e A = 3600
So, The amount in the saving account is $3600
∵ , The amount spent on refrigerator = × ( 3600 - 1600 )
Or, The amount spent on refrigerator = × 2000
I.e The amount spent on refrigerator = $ 800
Hence The amount spent on the refrigerator is $ 800 . Answer
Given that the integral is given as , Hence, we are required to find the area under the graph where t is between 0 and 12. The correct answer is 2 (Option A) See the explanation below.
An integral is a function of which a given function is the derivative, that is, when differentiated, it returns that function, and it can express the area under the curve of a graph of the function.
Hence the areas under the graph for the above function are given as:
12 + 6 + 2 + (-2) + (-16)
= 20-18
= 2
Notice that the following figures were arrived at by dividing the areas under the graph into common geometric shapes and deriving their area.
For example, the first three positive values were derived by dividing the positive part of the graph into two triangles and a rectangle.
The length of the rectangle is 6 while its height is 2
Area of a rectangle is L x W
= 6 * 2
= 12
It is to be noted that the areas under the curve are negative hence the negative results. See the attached image.
