Answer:

The area of the square is increasing at 90.51m^2/min

Step by step explanation:

Given;

Change in diagonal length ∆d = 8m/min

Length l = 8m

When l = 8m

d^2 = 2l^2 = 2×8^2 = 128

d = √128

Area of a square = l^2 = (d^2)/2

d = diagonal

Change in area = ∆A = dA/dd

∆A = 2 × d/2 × ∆d = d×∆d

∆A = √128 × 8 = 90.51m^2/min

My daughter needs help and I don't understand the question ethier.
WINSTONCH [101]

So firstly, let's figure out the expression for a singular goody bag. Since there's 2 of each item, a single goody bag is going to be (1.07*2+0.85*2+2.12*2)

Now since we have 7 friends who are all getting 1 goody bag, multiply the cost of the goody bag by 7, and our expression is 7(1.07*2+0.85*2+2.12*2) . Now we can solve it from there.

Firstly, solve the multiplication inside the parentheses: 7(2.14+1.7+4.24)

Now add up what's inside the parentheses: 7(8.08)

Lastly, multiply and <u>your answer will be $56.56</u>

What is the key difference between the graph of a linear relationship and the graph of a nonlinear relationship?
kakasveta [241]
<span>The main key difference between the graph of a linear relationship and the graph of a nonlinear relationship are linear relationship is the relation between variables which creates a straight line when spotted on a cartesian plane and linear relations have constant slope always.The key difference between the graph of an exponential relationship and the graph of a quadratic relationship is exponential relation is a mathematical function of the following form: f ( x ) = a x. where x is a variable, and a is a constant called the base of the function but quadratic relationship of the graph is the the standardized form of a quadratic equation is ax^2 + bx + c = 0,.</span>
