We know that this ratio is directly because the two magnitudes go up.
In this case we will get the <u>proportionality constant</u> by dividing any term of the second magnitude by the first.
<h3>For example: </h3>
Now that we know that k = 3, we can know how much "<u>y</u>" will be if <em>x = 5</em>.
We just multiply:
<h3>Answer: <u>y = 15</u></h3>
Answer:
16
Step-by-step explanation:
2x² - 5x - 17
Put x as -3 and solve.
2(-3)² - 5(-3) - 17
2(9) - (-15) - 17
18 + 15 - 17
= 16
<u>Given</u>:
The circumference of the smaller is 30% of the circumference of the larger circle.
We need to determine the circumference of the larger circle.
<u>Diameter of the larger circle:</u>
The diameter of the smaller circle is 9 in.
Since, the circumference of the smaller is 30% of the circumference of the larger circle, we have;
where S is the circumference of the smaller circle and L is the circumference of the larger circule.
Thus, the diameter of the larger circle is 30 inches.
<u>Circumference of the larger circle:</u>
The circumference of the larger circle is given by
Thus, the circumference of the larger circle is 94.2 inches.
Answer:
True
Step-by-step explanation:
The circumcenter is the center of the circumscribing circle, the circle that intersects each of the vertices. Since the points on a circle are equidistant from its center, the vertices of a triangle are equidistant from the circumcenter.
<h2>
Answer:</h2>
Area of triangle = Base×Height/2
Base of this triangle = 12 units
Height of this triangle = 4 units
Area=12×4/2 units² = 24 cm²
