Answer:
Linear equations can take several forms, such as the point-slope formula, the slope-intercept formula, and the standard form of a linear equation. These forms allow mathematicians to describe the exact same line in different ways.

Let
point
A----------------- > Bob
point
B----------------- > lamppost that is to Bob left
point
C----------------- > lamppost that is to Bob right
we know that
dAB=25 ft
dAC=30 ft
dBC=20 ft
see the attached
figure
we use the law of
cosines------------- > dBC²=dAB² +dAC² -2(dAB)(dAC)cos(alfa)
we have that
20²=25² +30² -2(25)(30)cos(alfa)--------
> cos (alfa)=(20²-(25² +30²))/(-2*25*30)
cos (alfa)=(400-(625 +900))/(-1500)= (400-(625 +900))/(-1500)=1125/1500=0.75
<span>alfa=arccos (0.75)= 41.4096 -------- > 41 °--------
> </span>∡ BAC
the answer
is 41 °
<h2>
The bond will be worth in total after 10 years is =$1,950</h2>
Step-by-step explanation:
Given,
Nora invested $1,500 in at a bond simple interest rate of 3%
here P= $1500 R= 3% and t = 10year
Simple interest(I) = 
=$ 
=$ 450
<h3>
The bond will be worth in total after 10 years is = $1,500+ $450</h3><h3>
=$1,950</h3>
The answer is going to be v= 4500ft3;S=900ft2
