Answer:
The fraction 7/8 is really close to 1 , so Yvonne could estimate that she needs approximately 6 yards of fabric per dress. So, to make 5 dresses, she would need approximately 30 yards.
Step-by-step explanation:
I'm not entirely sure, but 7/8 is very close to a whole, so this is what I would assume.

The population of the nanobots follows the equation

We must find the value of t such that the population of nanobots is 106 or more, that is

We'll solve the equation

Dividing by 5

Taking logarithms

By logarithms property

Solving for t

Answer:

Lenght of the equal sides: 
Step-by-step explanation:
You can observe in the picture that the triangle have two angles that have equal measure; therefore, it is an Isosceles triangle.
By definition, Isosceles triangles have two equal angles and two equal sides.
Based on this, you can write the following equation:

Solving for "x", you get this value:

Finally, you can subsitute the value of "x" into any expression to find the lenght of the equal sides:

Answer:
(See explanation and attachment below for further details)
Step-by-step explanation:
The parabola must satisfy the following conditions:


The expression for the x-intercepts are, respectively:
x = -3
![4 = C\cdot [(-3)^{2} - 2\cdot k\cdot (-3)+k^{2}]](https://tex.z-dn.net/?f=4%20%3D%20C%5Ccdot%20%5B%28-3%29%5E%7B2%7D%20-%202%5Ccdot%20k%5Ccdot%20%28-3%29%2Bk%5E%7B2%7D%5D)

x = 5
![4 = C\cdot [5^{2}-2\cdot k \cdot (5)+k^{2}]](https://tex.z-dn.net/?f=4%20%3D%20C%5Ccdot%20%5B5%5E%7B2%7D-2%5Ccdot%20k%20%5Ccdot%20%285%29%2Bk%5E%7B2%7D%5D)

By equalizing both expressions:



And,


The equation of parabola is:
