Answer:
Domain: x>-3 Range: y [tex]\geq[/tex]-5
Step-by-step explanation:
The domain at the left has an open circle, meaning it is not uncluded in the domain. The domain would start from there, not including -3, and go on towards positive infinity. The range, at its lowest starts at -5, including negatove 5, since it is a closed circle, and goes up from there.

If sin(t) = 3/5 and t is in the 2nd quadrant, find cos(t).
Cosine is [tex]\frac{hypotenuse}{adjacent}[/tex].
Apply the equation:
[tex]sin(t) = \frac{3}{5} \\3^2 + b^2 = 5^2\\b^2 = 5^2 - 3^2\\\\\sqrt{b^2} = \sqrt{5^2}- \sqrt{3^2}\\\\\\b = 5 - 3 \\\\b = 2[/tex]
B is the adjacent side so
cosine is:
Cos(t) = 5/2

A study took a group of adults and randomly divided them into two groups. One group was told to drink tea every night for a week, while the other group was told not to drink tea that week. Researchers then compared when each group fell asleep. Does this describe an observational research study or an experimental research study?
Answer:
2nd one
Step-by-step explanation:
experimental research
The case described here is an experimental research study.
In an experimental research study, the researcher deliberately manipulates one or more variables (in this case, whether or not the participants drink tea) and observes the effects on other variables (in this case, the time each group falls asleep). The researcher randomly assigns participants to different groups, ensuring that any differences observed between the groups can be attributed to the manipulation of the variable of interest.
In this scenario, the researcher randomly divided the adults into two groups and instructed one group to drink tea every night while the other group was told not to drink tea. By manipulating the variable (tea consumption) and comparing the outcomes (time of falling asleep) between the two groups, the study follows the experimental research design.

Three boys cut out hundredths decimal models. Fred does not shade any of his models. Edward shades nine tenths of one model. Jeff shades one model and seven tenths of another model. What decimal represents the amount each boy shades?
Answer:
Step-by-step explanation:
Fred does not shade any model
Edwards shades nine tenths : 0.9
Jeff shades shades seven tenths : 0.7
so add 0.9 + 0.7, you get 0.16 : sixteen hundredths .

Below are two different functions, f(x) and g(x). What can be determined about their y-intercepts? graph going through negative 1, negative 1 and negative 4, negative 1 x g(x) 4 9 6 13 8 17 (1 point) The function g(x) has a higher y-intercept. The function f(x) has a higher y-intercept. They both have the same y-intercept. The relationship between y-intercepts cannot be determined.
Answer:
The function g(x) has a higher y-intercept.
Step-by-step explanation:
First function f(x):
Slope = (-1, - (-1) / -4 - -1) = 0
So its equation is y = -1.
The y-intercept is (0, -1).
Second function g(x):
Slope = (13-9)/ (6-4) = 2.
y - y1 = m(x - x1) where m = slope and (x1, y1) is a point on the line, so we have:
y - 9 = 2(x - 4)
y = 2x - 8 + 9
y = 2x + 1.
So the y-intercept is (0, 1).
The accompanying bar graph shows the percentage of adults in a certain city who smoked cigarettes for selected years from 1970 through 2010.
The mathematical model p + x/2 = 40 describes the percentage, p, of adults who smoked cigarettes x years after 1970. Use this information to answer questions (a) and (b) below.
Does the mathematical model underestimate or overestimate the percentage of adults who smoked cigarettes in 2010? By how much? Select the correct choice below and fill in the corresponding answer box to complete your choice.
Finding the numerical value of the function, it is found that:
Considering that the percentage of smokers in 2010 is of 23%, while the model estimates at 20%, it is found that the model underestimated the percentage by 3%.
--------------------------------
The numerical value of a function f(x) at x = a is f(a).
--------------------------------
The percentage of smokers in x years after 1970 is given by:
[tex]p + \frac{x}{2} = 40[/tex]
Then
[tex]p(x) = 40 - \frac{x}{2}[/tex]
--------------------------------
2010 is 2010 - 1970 = 40 years after 1970, thus the percentage is p(40).
[tex]p(40) = 40 - \frac{40}{2} = 40 - 20 = 20[/tex]
Considering that the percentage of smokers in 2010 is of 23%, while the model estimates at 20%, it is found that the model underestimated the percentage by 3%.

Jay found 1/3 of a sheet cake in the kitchen. He ate 1/2 of it.What fraction of the whole cake did he eat?
Answer:
1/6
Step-by-step explanation:
Multiply the fractions to find how much of the whole cake he ate.
1/3 * 1/2
1/6
Best of Luck!
Answer:
1/6
Step-by-step explanation:
He ate 1/2 of 1/3 of the cake, so the fraction of the whole cake he ate is 1/2 x 1/3. Multiplying fractions is easy, simply multiply the numerator of each fraction (the numbers at the top of each fraction) and the denominator of each fraction (the numbers at the. bottom of each fraction). Therefore, 1/2 x 1/3 = 1/6.

An airplane is flying in a direction of 165° with an airspeed of 650 mph. The wind is blowing at 50 mph in a direction of N 30°E What is the ground speed and direction of the plane?
A) ground speed: 658 mph; direction 108°
B) ground speed: 639 mph; direction 161°
C) ground speed: 686 mph; direction 108°
D) ground speed: 698 mph; direction 161°
Direction is usually specified as bearing, however, with regards to vectors direction is specified relative to the positive, x-axis
The correct option for the ground speed and direction of the plane is option B
B) Ground speed: 639 mph; direction 161°
The given parameters are;
Direction of airplane = 165° (vector, measured from the horizontal x-axis)
Airspeed of airplane = 650 mph
The speed of the wind blowing = 50 mph
The direction of the wind = N30°E
Required:
The ground speed of the airplane
Solution:
The velocity of the airplane in vector form is found as follows;
[tex]\overset \longrightarrow P[/tex] = 650 × cos(165)·i + 650 × sin(165)·j ≈ -628·i + 168·j
The velocity of the wind in vector form is found as follows;
[tex]\overset \longrightarrow W[/tex] = 50 × cos(60)·i + 50 × sin(60)·j ≈ 25·i + 43·j
The sum of the vectors, [tex]\overset \longrightarrow R[/tex] = The ground speed, therefore;
[tex]\overset \longrightarrow R[/tex] = [tex]\overset \longrightarrow P[/tex] + [tex]\overset \longrightarrow W[/tex]
[tex]\overset \longrightarrow R[/tex] = (25 - 628)·i + (43 + 168)·j = -603·i + 211·j
The magnitude of the ground speed = √((-603)² + 211²) ≈ 639
The magnitude of the ground speed ≈ 639 mph
The direction, Φ ≈ arctan(211/(-603)) ≈ -19°
Φ is measured from the negative x-axis in the clockwise direction, therefore;
The direction of the airplane from the positive x-axis, in the anticlockwise direction, θ = 180° + Φ
θ = 180° + (-19) = 161°
The direction of the airplane measured from the positive x-axis, θ ≈ 161°
Therefore, the correct option is ground speed; 639 mph; direction 161°

the volume of a cuboid box is 60cm³.the length and breadth of the box are respectively 6cm and 2cm. calculate its height.
take a picture and send me the answer step by step ASAP
Answer:
height = 5 cm
Step-by-step explanation:
The volume (V) of a cuboid is calculated as
V = lbh ( l is length, b is breadth, h is height )
Here l = 6, b = 2 and V = 60 , then
6 × 2 × h = 60 , that is
12h = 60 ( divide both sides by 12 )
h = 5
That is height is 5 cm
