You probably jsut need to use law of cosines in order to solve for angle A

$c^2 = a^2+b^2 -2ab \cos C$
or
$a^2 = c^2+b^2 -2cb \cos A$

Answer:

if the prices at the bottom are per pound, then:

pears = 3.7604 (3.76)

apples = 1.1385 (1.13)

peaches = 2.8122 (2.81)

total bill = 7.07

Step-by-step explanation:

pears =

1.19 x 3.16 = 3.7604 (3.76)

apples =

0.99 x 1.15 = 1.1385 (1.13)

peaches =

1.29 x 2.18 = 2.8122 (2.81)

total bill =

3.76 + 1.13 + 2.81 = x

x = 7.7

7.7 money-wise = 7.07 <em><u>(i think)</u></em>

total bill = 7.07

total bill =

3.7604 + 1.1385 + 2.8122 = x

x = 7.7111

----------------

7.7111 = 7.7 = 7.07

Given the function f(x) = 4^x - 1, explain and show how to find the average rate of change between x = 1 and x = 4.

soldier1979 [14.2K]

Answer:

Step-by-step explanation:

f(1)=4^1 - 1 = 3

f(4) = 4^4 - 1 = 255

rate of change = $\frac{f(x_2)-f(x_1)}{x_2-x_1}$

(255 - 3) / (4 - 1) = 252 / 3 = 84
