In the diagram below, XY is
tangent to OC at point P.
What is m
Answer:
90
Step-by-step explanation:
Tangents meet the end of a radius that is not at the center of a circle.
The tangent makes a 90 degrees angle with that end of the radius.
Answer:
m<CPX = 90°
Step-by-step explanation:
The line tangent to a circle states that when a line is a tangent to a circle, a radius that is drawn from the center to the circle to the point of tangency will be perpendicular to the tangent line
Apply this theorem to the given circle, one can state that (m<CPX= 90°) and (m<CPY = 90°), since (XY) is tangent to the circle will radius (CP).

Find the area of the shaped region
Answer:
Assuming π is represented by 3.14, the correct answer is [tex]50.24m^2[/tex].
Step-by-step explanation:
Because the question is asking for the area of the shaded region, you can ignore the non-shaded versions of the diagram. The formula of finding the area of a circle is [tex]\pi r^2[/tex], where r is the radius of the circle. Since the radius of the shaded circle is [tex]4m[/tex], you can infer that the area of the shaded region would be [tex]4^2 * 3.14[/tex] = [tex]16*3.14[/tex] = [tex]50.24m^2[/tex].

A lake near the Arctic Circle is covered by a 222-meter-thick sheet of ice during the cold winter months. When spring arrives, the warm air gradually melts the ice, causing its thickness to decrease at a constant rate. After 333 weeks, the sheet is only 1.251.251, point, 25 meters thick.
Let yyy represent the ice sheet's thickness (in meters) after xxx weeks.
Complete the equation for the relationship between the thickness and number of weeks.
y=y=y, equals
Answer:The question is a little incorrect, the ice sheet thickness should be 2m and not 222m.
The required function formula is,
S(t) = 2 - 0.25 t
Step-by-step explanation:
Here, the initial thickness of the ice sheet = 2 meters,
After 3 weeks, the thickness of ice sheet = 1.25 meters
Total changes in the thickness in 3 weeks = 2 - 1.25 = 0.75 meters,
⇒ Total changes in the thickness in 1 weeks = 0.75/3 = 0.25 meters,
Since, the ice is melting with the constant rate.
⇒ The rate of ice decreasing = 0.25 meters per week.
⇒ Total changes in t weeks = 0.25 t meters
The new thickness of ice after t weeks = Initial thickness - Total changes in t weeks.
⇒ S(t) = 2 - 0.25 t
Which is the required function's formula.

What is proportion?In general, the term "proportion" refers to a part, share, or amount that is compared to a total.
According to the concept of proportion, two ratios are in proportion when they are equal.
From the triangle it can be assume that ΔPSR is similar to ΔPQR.
Then, the ratio of corresponding sides of triangles are proportion.

If the ratio of beakers to test tubes in a lab is 3:8, and there are 64 test tubes, how many beakers are there?
64 + 64 = 128. 128 is 6/8
128 is 75%
[tex]\frac{75}{100} = \frac{128}{y}[/tex]
y should be 171 or 172
The number of beakers in the lab are 24.
What is the ratio?The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.
Given that, the ratio of beakers to test tubes in a lab is 3:8, and there are 64 test tubes.
Let the beakers be 3x and the number of test tubes be 8x
The number of test tubes =8x=64
x=8
So, the number of beakers =3x=24
Therefore, the number of beakers are 24.

Earth. During the first quarter, half of the side of the moon facing the Earth is visible. During a full moon the entire

Answer:

Step-by-step explanation:
Got it right on the practice :)
Based on the data presented , the answer is that Yes, it show repeated and periodic behavior. and thus the data indicate that a sine regression is appropriate in this case.
What leads to a new moon phase?This occurs as our Moon is said to orbits around Earth. the side of the moon that is facing the Sun is said to be illuminated due to the sun's brightness, just like when the Earth's daylight side is also said to be illuminated by the Sun.
We tend to have a “new Moon” only when our Moon is said to orbit around the Earth and thus moves it between Earth and the Sun.
See options below
Using the information above, plot the data points. Does this data indicate that a sine regression may be appropriate in this case?
a. Yes, it shows repeated and periodic behavior.
b. Yes, it shows a curve increasing from left to right.
c. No, the points are random.
d. No, the points depict a parabola.
