Answer:
![cos^{-1} (\frac{8}{[tex]\sqrt{113}](https://tex.z-dn.net/?f=cos%5E%7B-1%7D%20%28%5Cfrac%7B8%7D%7B%5Btex%5D%5Csqrt%7B113%7D)
} )[/tex]
Step-by-step explanation:
Given two vectors a and b,we are rquired to find the angle between them.
a=(8,7);b=(7,0).
Angle between two vectors can be found by dot product of them.
If a and b are two vectors then the dot product of them is given by|a||b|cos(α).
Where α is the angle between the vectors a and b.
Now 
. and 
=56.
Now cosα=
so α= cosine inverse of that.
∴α=

Answer: The expenses of the fundraiser is $1500
Step-by-step explanation:
P(n) models the fundraiser's profit (in dollars) where n represents the number of tickets that are sold. The equation is expressed as
P(n) = 70n - 1500
A negative profit means the expenses exceeded the income from tickets. Looking at the model, for the charity organization to make profits, the product of the number of tickets sold and the cost per ticket must exceed $1500. If it is below $1500, then it is a negative profit. This means that the expenses is $1500
