Answer:
246.5 seconds
Step-by-step explanation:
4.25x58=246.5
First you check for Pythagoras' Theorem.
Is 8.6² = 8.1² + 2.6² ?
8.1² + 2.6² = 65.61 + 6.76 = 72.37
8.6² = 73.96
8.1² + 2.6² ≠ 8.6²
Since Pythagoras' Theorem is not satisfied it is not a right angled triangle.
The longest side is 8.6, let's find the angle facing the longest side 8.6.
By cosine formula CosA = (b² + c² - a²) / (2bc)
CosA = (2.6² + 8.1² - 8.6²) / (2*2.6*8.1) = -1.59/42.12 = -0.0377
A = Cos inverse (-0.0377) = 92.1 degrees
So there is an angle is greater than 90 degrees.

do u know the answer? can u teach me pls?
Step-by-step explanation:
Given
Grant and Pedro are comparing their stocks for the week
On Monday, their results were opposite.
for Monday if Grant lost $4
Explain how you would graph their results for Monday.
To proof
let us assume that value of stocks after a week = x
As given in question
for Monday if Grant lost $4
i.e x= - $4
result were opposite for grant and pedro.
thus
for Monday if Pedro gain $4
i.e x = $4
Therefore two values are
x = -4 and x = 4 is shown in graph given below.
This shows that x = -4 lies left of 0 to x-axis and x = 4 lies right of 0 to x- axis.
