A formula models real-world phenomena when it describes the relationship between the variables of a real life situation. We use formulas in our every day life, but maybe are not aware of it. Some examples of using math formulas in the real world are: - the most obvious example is that we use formulas in the grocery store (multiplication, estimation, percentages,...

- we use formulas while baking (measuring ingredients, understanding ratios and proportions,<span> converting metrics,...)</span>

Vika [28.1K]
Reflection across the y axis means multiply the whole function by -1

so

f(x)=3x+12
times -1
g(x)=-3x-12 is the answer


answer is C
not sure why you put an arrow to choice A, but it's wrong

Regular quadrilateral prism has an altitude h = 11 cm and base edges b=8 cm. Find the sum of all edges.
natka813 [3]
The first thing we will do is assume that the prism is square based.
 We have then that the edges of the base are:
 P = 4L
 P = 4 (8)
 P = 32 cm
 The edges of the top of the prism are:
 P = 4L
 P = 4 (8)
 P = 32 cm
 The edges of the prism height are:
 P = 4h
 P = 4 (11)
 P = 44 cm
 The total sum will be:
 Pt = 32 + 32 + 44
 Pt = 108 cm
 Answer:
 
the sum of all edges is:
 
Pt = 108 cm
