The length of a rectangle is increasing at a rate of 8 cm/s and its width is increasing at a rate of 6 cm/s. When the length is 7 cm and the width is 4 cm, how fast is the area of the rectangle increasing?
Given :
The length of a rectangle is increasing at a rate of 8 cm/s and its width is increasing at a rate of 6 cm/s. When the length is 7 cm and the width is 4 cm .To find :-
how fast is the area of the rectangle increasing?Solution :-
As we know that :-
A = lbTo find the rate :-
d(A)/dt = d(lb)/dt .Differenciate :-
dA/dt = l (db/dt ) + b (dl/dt )Substitute :-
dA/dt = 6*7 + 4* 8 dA/dt = 42 + 32 cm²/s dA/dt = 74 cm²/sWhat is the sum of the first 7 terms for the geometric sequence with first term 3, seventh term 46,875, and common ratio 5
A. 35,154
B. 58,593
C. 19,531
D. 11,718
The sum of the given geometric sequence with first term 3 and seventh term 46875 is 136717 so none of the given options are correct.
What is geometrical progression series?A geometric progression is a sequence in which any element after the first is obtained by multiplying the previous element by a constant which is called a common ratio denoted by r.
Given that,
First term (a) = 7
Common ratio r = 5
Seventh term = 46875
The sum of the first n term in GP is given as,
[tex]S_{n} = a(r^n-1)/(r-1)\\[/tex]
Sum of first seventh term,
S₇ = 7(5⁷ - 1)/(5-1)
S₇ = 136717
Hence "The sum of the given geometric sequence with first term 3 and seventh term 46875 is 136717 ".

0.75*(x)*(y)
Step-by-step explanation:
Eric is hiring a company to install carpeting in his house. The company charges a one-time installation fee plus a certain amount per square yard of carpeting. The graph below shows the relationship between the number of square yards of carpeting and the total cost, in dollars.
A. Slope of the graph
B. Y-intercept of the graph
C. Domain of the function
D. Range of the function
Answer:
As axjames said, it is A. Slope of the graph.
Step-by-step explanation:
A slope in a graph can mean a increase or a decrease in whatever. For example a decrease in miles per hour (mph), business sales, and more. Also don't forget slopes with decrease are negative slopes and slopes with increase are positive slopes. A positive slope moves upward on a graph from left to right. A negative slope moves downward on a graph from left to right. It's important to note that we work from left to right when dealing with slope.
The graph of a linear equation is a straight line.
The quantity that represents the cost per square yard of carpeting is the (a) slope of the graph.
The slope of the graph is the rate of change of the total cost over the change in square yard.
This means that:
The slope of the graph is the cost per square yard of the carpet.
Hence, the required quantity is (a)

Factor out 7 from the expression and remaining will be[tex]7(7x - 1)[/tex]
Hence,Option C is correct..The solution is: Option C is correct. Factor using the GCF: 49x - 7 is
7(7x-1).
Here, we have,
given that,
we have to factor using the GCF: 49x - 7.
we know that,
In mathematics, the greatest common divisor of two or more integers, which are not all zero, is the largest positive integer that divides each of the integers. For two integers x, y, the greatest common divisor of x and y is denoted {\displaystyle \gcd}.
so, we have,
49x - 7
now, we know,
7 * 7 = 49
and, 7 * 1 = 7
so, we get, the GCF of 49 and 7 is 7.
so, we have,
Factor out 7 from the expression and remaining will be.
7(7x-1)
i.e. 49x - 7 = 7(7x-1)
Hence, Option C is correct. Factor using the GCF: 49x - 7 is 7(7x-1).
