Answer:
Step-by-step explanation:
Shape of the can is cylinder
r = 4 in
h = 15 in
Volume =πr²h
= 3.14* 4 * 4 * 15
=753.6 cubic inches
Answer:
$300
Step-by-step explanation:
Let Dave's saving be D and Sam's savings be S
- <u>"At first, the ratio of Dave's savings to Sam's savings was 5:4":</u>
- <u>"After each of them donated $40 to charity, the ratio of Dave's savings to Sam's savings became 13:10":</u>
<em>So we subtract 40 from each of them and then the ratio becomes 13 is to 10. Hence we can write:</em>
<em>Plugging in into S (as we found earlier), we can solve for D (our answer):</em>
So, Dave's savings at first, D, is $300.
Answer:
g=4
Step-by-step explanation:
Move all terms not containing g to the right side of the equation.
-7g-2=-30
-7g=-28
g=-28/-7
g=4
To add the variables, add the coefficients with same variable. The expression which is equivalent to given expression is . The option 2 is the correct option.
<h3>What is
equivalent expression?</h3>
Equivalent expression are the expression whose result is equal to the original expression, but the way of representation is different.
Given information-
The expression given in the problem is,
Let the resultant expression of the above expression is . thus,
To add the algebraic terms open the brackets first,
Separate the same variable terms,
To add the variables, add the coefficients with same variable. Thus,
Hence, the expression which is equivalent to given expression is . The option 2 is the correct option.

Answer:
1.5 unit^2
Step-by-step explanation:
Solution:-
- A graphing utility was used to plot the following equations:
- The plot is given in the document attached.
- We are to determine the area bounded by the above function f ( x ) subjected boundary equations ( y = 0 , x = -1 , x = - 2 ).
- We will utilize the double integral formulations to determine the area bounded by f ( x ) and boundary equations.
We will first perform integration in the y-direction ( dy ) which has a lower bounded of ( a = y = 0 ) and an upper bound of the function ( b = f ( x ) ) itself. Next we will proceed by integrating with respect to ( dx ) with lower limit defined by the boundary equation ( c = x = -2 ) and upper bound ( d = x = - 1 ).
The double integration formulation can be written as:
Answer: 1.5 unit^2 is the amount of area bounded by the given curve f ( x ) and the boundary equations.
