Answer:

So you need to compute all the rates to see which is the best deal.

$1.79/12.5ft^2=$0.1432 per ft^2

$5.29/40ft^2=$0.13225 per ft^2

$8.49/50ft^2=$0.1698 per ft^2

$6/60ft^2=$0.10 per ft^2

So the last option is the cheapes per square foot and thus is the best deal. Ordered from least to greatest.

Answer:

y=a|x-h|+k (absolute value function)

a= 3/5 (a easier way to know is it is somehow basically the slope of the line but it must be positive.)

h= -3 (you are correct)

k= -1 (you are correct)

Tan 1.1 – tan 4.6/

VladimirAG [237]

The value of the given equation is –0.37458.

Solution:

Given equation is:

$$\frac{\tan 1.1-\tan 4.6}{1+\tan 1.1 \tan 4.6}$

Let us first find the values.

The value of tan 1.1 = 1.96475

The value of tan 4.6 = 8.86017

Substitute these values in the given equation.

$$\frac{\tan 1.1-\tan 4.6}{1+\tan 1.1 \tan 4.6}$

$$=\frac{1.96475-8.86017}{1+1.96475 \times 8.86017}$

$$=\frac{-6.89542}{1+17.4080}$

$$=\frac{-6.89542}{18.4080}$

= –0.37458

$$\frac{\tan 1.1-\tan 4.6}{1+\tan 1.1 \tan 4.6}=-0.37458$

Hence the value of the given equation is –0.37458.
