Answer:

9.3 centimeters

Step-by-step explanation:

If the length of the third side of the triangle is c, then according to the Law of Cosines, c2 = 72 + 132 – 2(7)(13)(cos 44°). The value of c2 can be simplified to approximately 49 + 169 – 130.9198, or 87.0802, using a calculator. By taking the square root of 87.0802, the length of the third side of the triangle comes out to be approximately 9.3 centimeters.

A suit is on sale for 33% off the sale price is 536 what is the regular price
nataly862011 [7]

Answer: sale: 536

discount: 33%

33/100*536=

Step-by-step explanation:

1- I assume the cost of the suit is $536, not 536%.

So the % of the part times $536= Original price

Remember, $536 is 77% of the original price.

536x0.77=$696.10

Since the suit was 33% off, and since the sale price of the suit was $536

Then the suit was sold for 67% of its original price

Therefore, 67% of its original price (p) equals $536, or .67(p) = 536

.67p = 536

p = 536 � .67 = $800

Original price of suit was $800

Drag the point around to graph more horizontal lines. What is the general equation of a horizontalline?
svetlana [45]

A horizontal line is one for which the value of y is the same for the entire length of the line. Therefore this type of line can be expressed as below:

y=c

Where "c" is a constant that changes the position of the line on the coordinate plane. If c is equal to 2, then we have a constant line that crosses the y-axis at the position 2 for example.

Suppose that y varies inversely with x.Write an equation for the inverse variation Y=4 when x=7
myrzilka [38]

Answer:

If y varies inversely as x, then we write it as:

y = k/x


where k is some constant.


If we multiply both sides of this equation by x we get an equation for k:

k = x*y


We are given that y=4 when x=7, therefore:

k = 7*4 = 28


Put this back into our original equation to get:

y = 28/x
