Answer:
A. between 3.0 and 3.5 and between 4.0 and 4.5
Step-by-step explanation:
The idea here is that if a function is continuous and you have points on opposite sides of the x-axis, then there must be a zero-crossing between those points. As the table and graph show, ...
... (3.0, 4.0) and (3.5, -0.2)
are points on opposite sides of the x-axis. So, there must be a zero crossing between x=3.0 and x=3.5.
Likewise, ...
... (4.0, -0.8) and (4.5, 0.1)
are points on opposite sides of the x-axis. So, there must be a zero-crossing between x=4.0 and x=4.5
The appropriate answer choice lists both of these possible zero crossings.
Answer:
Ratio = 3.801
Step-by-step explanation:
Given that the total assets balance at the beginning of the year was $175,000 and at the end of the year was $167,000.
Average assets for the year = ![\frac{175000+167000}{2} =171000](https://tex.z-dn.net/?f=%5Cfrac%7B175000%2B167000%7D%7B2%7D%20%3D171000)
Sales for the year = 650000 dollars
To calculate the ratio of sales to total assets:
Required ratio = ![\frac{650000}{171000} =3.801](https://tex.z-dn.net/?f=%5Cfrac%7B650000%7D%7B171000%7D%20%3D3.801)
As the regular pentagon there is 5 regular triangles.
And the area of 1 regular triangle is:
At = Side^2 × √(3)/4
But, as the pentagon has 5 triangle
Then,
Ap = 5 × Side^2 . √(3)/4
Replacing Ap = 6.9
5 × Side^2 . √(3)/4 = 6.9
Side^2 . √(3)/4 = 6.9 ÷ 5
Side^2 . √(3) = 4 × 1,38
Side^2 = 5,52 ÷ √(3)
Side^2 = 3,187
Side = √(3,187)
Side = 1,785 cm
Then,
The total perimeter will be:
P = 5 × Side
P = 5 × 1,785
P = 8,92 cm
Well, I did find this answer.
Answer:
The focii are 8 feet apart
Step-by-step explanation:
You can use the formula
F = √(a^2 - b^2) where F is the distance of the focii from the center , a = length of the semi major axis and b = length of the semi minor axis)
So here it is √(5^2 - 3^2)
= √16 = 4
So the distance is 2*4 = 8
