Step-by-step explanation:
let the price of 6 hats be x
and price of 7 t shirts be x+6
x+x+6=$86
2x=86-6
x=80/2
x=40
price of 6 hats=40
price of a hat =40/6=$6.33
price of 7 t shirts =40+6
price of a t shirt = 46/7 =$6.57
Since pi is irrational and it is used in the formula, we cannot give an exact answer except in terms of pi (we can give an aproxamation using 3.14 =aprox pi, but it is not exact)
ok
circumfernce=2pir
r=15
circumference=2pi15
circumference=30pi
exact=30pi cm
if you want to aprox pi=3.14 then
aprox circumfernce=94.2 cm

Answer:c
Step-by-step explanation: By graph, it is clear that the closest time for lunch is 1:40pm as she spent more time in hiking after a constant time.
2a)
To verify, set the factors to zero.
(x - 2) = 0, x = 2
(x + 3) = 0, x = -3
Insert zero's in the equation:
<u>when x = 2</u>
3(2)³ + 2(2)² - 19(2) + 6 = 0
<u>when x = -3</u>
3(-3)³ + 2(-3)² - 19(-3) + 6 = 0
Hence verified the factors.
2b)
The remaining factor is (3x - 1)
2c)
Set the factors to zero to find real zeros of f
2d)
<u>Complete factorization</u>: (3x - 1)(x - 2)(x + 3)
