Answer:

$319.43

Step-by-step explanation:

Monday= 4 * $11.52= $46.08

Tuesday= 4.5 * $11.52= $51.84

Thursday= 7.25 * $11.52= $83.27

Saturday= 12 * $11.52= $138.24

When you add all of those together you get $319.43

hope this helped (:

rectangle has dimensions 12 litre into 6 CM if you draw a square on the same perimeter what will be its area

Ber [7]

Answer:

$Area = 81cm^2$

Step-by-step explanation:

Given

$Length = 12$

$Width = 6cm$

Required

Determine the area of a square with the same perimeter

First, calculate the perimeter (P) of the rectangle.

$P=2*(Length + Width)$

$P=2*(12 + 6)$

$P=2*18$

$P=36$

The perimeter of a square is:

$P = 4L$

Where L is the side length.

Substitute 36 for P

$36 = 4L$

Make L the subject

$L =\frac{36}{4}$

$L =9$

The area of the square is:

$Area = L^2$

$Area = 9^2$

$Area = 81cm^2$

Look at Figure 2. What is the measure of x ? ( Hint: you may need to use triangle ACE to help you;) notice the right angle??? NE

kow [346]

Answer:

60°

Step-by-step explanation:

Let angle BAE = angle ACD = x

BCD = AEC = 60°

EAC + FCA + ECF + AEC = EAC + x + 60° + 60° = 180°

EAC = 60° - x

BAC = EAC + BAE = 60° - x + x = 60°

The graph of the function f(x) = 5 cos (2x) is a reflection over the x-axis of the graph of g(x) =

Zarrin [17]

Answer:

$g(x)=-5\cos (2x)$

Step-by-step explanation:

The given function is

$f(x)=5\cos (2x)$

If a function reflected over the x-axis, then x-coordinate remains same but the sign of y-coordinate is changed.

$P(x,y)\Rightarrow P'(x,-y)$

If function f(x) is a reflection over the x-axis to get the of g(x), then the resultant function is

$g(x)=-f(x)$

Substituting the value of function f(x), we get

$g(x)=-5\cos (2x)$

Therefore, the required function is $g(x)=-5\cos (2x)$ .
