How many solutions does this equation have? d − 3 = –3 + d

1 answer:

4 0

It has an infinite amount of solutions.

Explanation:
d-3 = -3+d which can be arranged as: d-3=d-3
Since they are equal to each other, no matter what number you input, your solution will be the same which means that there are an infinite amount of solutions. Let’s put this to the test and put in 5 for d. 5-3=5-3 is 2=2. They are equal to each other which means: infinite solution.

Indicate which formula you would use to solve for the missing side B and then write your answer correct to two decimal places.Wr

Answer:

The measure of the angle $b$ is approximately 44.040°.

Step-by-step explanation:

We need to apply Law of the Sine to determine the value of angle $b$ , since the length of the side opposite to this side and another side length and its opposite angle are known. That is:

$\frac{3.6}{\sin b} = \frac{5.1}{\sin 100^{\circ}}$

$\sin b = \frac{3.6}{5.1}\times \sin 100^{\circ}$

$b = \sin^{-1}\left(\frac{3.6}{5.1}\times \sin 100^{\circ} \right)$

$b \approx 44.040^{\circ}$

The measure of the angle $b$ is approximately 44.040°.

What is the circumference of the circle if r = 3,5 feet?

Nady [450]

Answer:

21.98

Step-by-step explanation:

C=2πr C=2d are the formulas of circumference so that would mean the diameter of the circle is 7 since 2 times the radius is the diameter. We then multiply the diameter 7 by PI to get 21.98
