The correct  answer is the option "B":

 B.(-x-6i)(x-6i)

 Explanation

 You must keep in mind the following:

 1. By definition, a complex number has the following form:

  a+bi

 "a" is the real part and "b" is the imaginary part.

 2. i²=-1

 3. Then,you have:

 (-x-6i)(x-6i)=(-x²+(6i)²)=-x²-36

 4. Therefore, the answer is: (-x-6i)(x-6i)

19. A spherical balloon has a circumference of 19cm. what is the approximate surface area of the balloon to the nearest square c
Tamiku [17]
The main formula of a spherical surface area is SA= 4 x Pi x r²
the circumference is C= 19cm =2 Pi r, so r = C/ 2Pi = 19 / 6.28 =3.02cm
so the surface area can be found by computing
SA= 4x 3.14x 3.02² =114.5, the nearest square centimeter is <span>A) 114 cm^2</span>

STALIN [3.7K]

Guven:

Miles per day = 34 miles

Number of days = 5 days

To find the total distance(miles), we have:

Total distance = distance covered per day x Number per days

Is the answer 4/5 ? Can someone help please ?
Zina [86]

Answer:

m=-\frac{4}{5}

Step-by-step explanation:

We can take 2 arbitrary points in the graph and solve for slope using the formula shown below.

<u>Note:</u> we will use the 2 points (2,-3) & (-3,1)

Where x_1 = 2, y _1 = -3  and  x _ 2 = -3 and y _ 2 = 1

The formula:

m=\frac{y_2-y_1}{x_2-x_1}

Let's plug the numbers and find the slope:

m=\frac{1-(-3)}{-3-2}\\m=\frac{4}{-5}\\m=-\frac{4}{5}

Hence, thsi is the slope.
