Find an equation in x and y that has the same graph as the polar equation. r sin(θ) = −2

Note that r sin theta  always equals "x" in polar coordinates. 

Thus, x = -2.  That's the graph in the upper, right-hand corner.

Solve x – 7 > –8.
IgorC [24]
Question 1.

x - 7 > - 8

Adding 7 to both sides, we get:

x - 7 + 7 > - 8 + 7

x > -1

Thus the answer to the inequality is option Fourth.

Question 2.

A number exceeds 66. Let that number be x. The number exceeds 66 means that the number is larger than 66. So in form of an expression we can write the inequality as:

x is greater than 66

x > 66

So, option 1st gives the correct answer.


Question 3.

The tiles are square shaped and area of a square can be calculated as the square of its Length.

Area of square = (Length)²

If we are given the Area, we can find the length as:

Length = \sqrt{Area}

For Tile A, the length will be:

Length= \sqrt{9}=3  
So length is a Rational number

For Tile B, the length will be:

Length= \sqrt{25}=5  
So length is a Rational number

For Tile C, the length will be:

Length= \sqrt{34}  
So, Length is not Rational.

For Tile D, the length will be:

Length= \sqrt{76}  
Length is not Rational

Thus, the lengths of Tile A and Tile B are rational only.

Therefore, the correct answer is 1st option

Find:
JulijaS [17]

Answer:

a) 15 ÷ 2/3=

=1 5 x 3/2=45/2

b) 3 × 1/8 × 6/9

=1/8 x 2(  Simplify 3 with 9 remainder 3, reduce

6 with 3 remainder 2)

=1/4

c) 3 3/5 ÷ 2 2/5

=18/5 : 12/5

=18/5 . 5/12

=3/2

d) 2 1/12 × 1 1/5

= 25/12 . 6/5

=5/2

The perimeter of a triangle is 65 meters. The second side is 5 meters less than the first side The third side is 7
tangare [24]

Answer:

The length of each side is 31.5m, 26.5m, 7m

Step-by-step explanation:

Let the length of the first side of the triangle be x meters.

Then, the second side is x-5 meters.

The third side is given as 7 meters.

The perimeter is 65 meters

This gives us the equation:

65 = x + x - 5 + 7

65 - 7 + 5 = x + x

63 = 2x

x =  \frac{63}{2}  = 31.5

The length of each side is 31.5m, 26.5m, 7m

If f(x) = 3^x + 10x and g(x) = 2x - 4, find (f + g)(x)
allsm [11]

Answer:

3^x + 12x -4

Step-by-step explanation:

f(x) = 3^x + 10x

g(x) = 2x - 4,

(f + g)(x) = 3^x + 10x +  2x - 4

Combine like terms

             = 3^x + 12x -4
