Center: (-13, -14) Point on Circle: (-13, -19)

Mathematics
1 answer:
SpyIntel [72]3 years ago
4 0

Answer:

(X + 13)² + (Y + 14)² = 25

Step-by-step explanation:

(X - H)² + (Y - K)² = R²

According to this Circle Equation, all negative symbols give the OPPOSITE terms of what they really are, which is why you see a 13 and 14 in the parentheses [-(-13) = 13; -(-14) = 14]. So, you plug the center into the formula, where <em>H</em> is the <em>phase shift</em> [<em>horizontal shift</em>] and <em>K</em> is the <em>vertical </em><em>shift</em>. Now, to find the radius, we have to find the range in between the <em>K</em><em> </em>and the y-coordinate of the Point of the Circle, so we do this:

-14 + ? = -19

5 = ? [Radius]

Now that we have our radius, we need to square it, so 5² is 25, there R² is 25.

I am joyous to assist you anytime.

Elza [17]
Not sure I'm right but:

If the bar weighs 9.25 ounces and 65% of the bar is gold, you'd do 65% of 9.25. So the answer would be <span>65% of 9.25= 6.0125</span>

A total of 200 10-year-old children of similar intellectual abilities participated in a noise experiment in their classrooms. Th
Vladimir79 [104]

Answer:

The dependent variable for this experiment is the ability of students with similar intellectual abilities to recall the meaning of a symbol in a textbook one week after the start of the experiment which depends on the presence or absence of noise outside the classroom.

Step-by-step explanation:

In an experiment, the independent variable is the one whose value, form or outcome is not determined by any other variable in the experiment.

The dependent variable is the one whose value, form or outcome is determined by one or more other variable(s) in the experiment.

This experiment tests the abilities of students with similar intellectual abilities to recall the meaning of a symbol in a textbook one week after the start of the experiment.

This ability was made to depend on whether there was noise or no noise outside their classrooms.

Since, this variable to be measured is determined by another variable in the experiment, it is evident that this is the dependent variable for this experiment.

Hope this Helps!!!
