Answer:
$ 1249.6
Step-by-step explanation:
given,
cost of saddle = $534.00
riding chaps cost = $87.02
boots cost = $143.99
hat cost = $55.87
pairs of glove cost = $15.94
sales tax paid = 7.5%
Sam's lesson cost = $35.00 per lesson
number of lesson = 10
Total purchase cost
= $534.00 + $87.02 + $143.99 + $55.87 + $15.94
= $ 836.82
cost included sales tax
= 1.075 x $ 836.82
= $ 899.58
Cost of lesson = 10 x $35.00 = $350.0
Total cost of the Sam
= $ 899.58 + $350.0
= $ 1249.58
= $ 1249.6

Answer:
r = -12cos(θ)
Step-by-step explanation:
The usual translation can be used:
Putting these relationships into the formula, we have ...
(r·cos(θ) +6)² +(r·sin(θ))² = 36
r²·cos(θ)² +12r·cos(θ) +36 +r²·sin(θ)² = 36
r² +12r·cos(θ) = 0 . . . . subtract 36, use the trig identity cos²+sin²=1
r(r +12cos(θ)) = 0
This has two solutions for r:
r = 0 . . . . . . . . a point at the origin
r = -12cos(θ) . . . the circle of interest
Answer:
A. 6.5
Step-by-step explanation:
First we find the average
of the 9 data:

Where n is the data number, that in this case is 9.

The formula of the standard deviation
is:

We replace the data and find the value of the standard deviation:


We approximate the number and the solution is 6,5
