Answer:

1 1/4 yards

$20

Step-by-step explanation:

The amount of fabric more that she needs can be determined by subtracting the sum of the yards needed for the shawl and the dress from the fabric she has

sum of the yards needed for the shawl and the dress =

2\frac{1}{2} + 1\frac{3}{4}

3\frac{2 + 3}{4} = 3\frac{5}{4} = 4\frac{1}{4}

Yards needed

4\frac{1}{4} - 3 = 1\frac{1}{4}

cost of dance outfit = $16 x 1\frac{1}{4}

\frac{5}{4} × $16  = $20

Determine the dimensions of a rectangular solid (with square base) with a maximum volume if its surface are is 337.5 square cent
juin [17]
The question is asking to determine the dimension of a rectangular solid with a maximum volume if its surface area is 337.5 square centimeters and base on my further computation, I would say that the answer would be x= sqrt 56.25 and y = 7.5 and having a maximum volume of 421.875. I hope this would help

Find the average rate of change of k(x)=5x–19 over the interval [<br> -<br> 14,<br> -<br> 4].
rusak2 [61]
The rate of change of a function can be modeled with the following expression:

\frac{\Delta{k{x)}}{\Delta{x}}

Where Δx is the change in x value, and Δk(x) is the corresponding change in k(x). We're given the two extremes of x, so we can calculate the change in x to be

\Delta{x}=-4-(-14)=10

To find the change in k(x), we can calculate the values of k(x) at x = -14 and x = -4 and find the difference between them:

k(-14)=5(-14)-19=-70-19=-89\\ k(-4)=5(-4)-19=-20-19=-39\\ \Delta{y}=k(-14)-k(-4)=-89-(-39)=-50

So, the rate of change for the function from x = -14 to x = -4 is

\frac{\Delta{y}}{\Delta{x}}= \frac{-50}{10}=-5

Which is an exponential decay function
Vikentia [17]

Answer:

Step-by-step explanation:

The last answer choice is the correct one.  The common ratio here is 0.7, which is between 0 and 1, an important criterion for recognizing an exponential decal function.  Every time x increases, f(x) will decrease.
