Attachment 1=Solution 1Attachment 2=Solution 2An air traffic controller is monitoring the altitudes of four planes. The four equations below show y, the
distance in feet of each plane above the ground, after 6 minutes of descent. (Hint: Look at the slopes to help
you.)
Plane A: y = 400t + 12,000
Plane B: y = -800t + 28,000
Plane C: y = -200t +13,500
Plane D: y = -500t + 30,000
a. Which plane is descending at the slowest rate?
b. Which plane began its descent from the highest altitude?
Answer:
Step-by-step explanation:
a. Plane C has the slowest rate of descending.
b. Place D has begun to descend from the highest altitude.
What is the equation of a line in slope intercept form?The equation of a line in slope intercept form is y = mx + b where the slope is m and the y-intercept is b.
The altitude of four planes is represented by y after 6 minutes and t represents time in minutes.
To determine which plane is descending at the slowest rate we have to look for a slope in these four equations which is the least steep or which modulus value is the least.
If we take the modulus of all four slopes 200 is the least value.
∴ Plane C has the least descending rate.
To determine which plane starts descending from the highest altitude we look for the value of y-intercept which is the largest among them and that is plane D.

why is it important to have a random sample for your data in statistics?
Answer:The simplest random sample allows all the units in the population to have an equal chance of being selected. ... Perhaps the most important benefit to selecting random samples is that it enables the researcher to rely upon assumptions of statistical theory to draw conclusions from what is observed.

a regular pentagon is divided into 5 isoscleles triangles work out the size of angle x angle y angle z
x = 72
y = 54
z = 54
================================================================
The regular pentagon has all five sides the same length. It also has all interior angles the same measure. This leads to y = z. These two angles are the congruent base angles of the isosceles triangle. The base angles are opposite the congruent sides.
The fact that we have a regular pentagon also means that the five triangles shown are identical copies of one another (i.e. they are congruent triangles). Divide the full 360 degree rotation into 5 parts to get 360/5 = 72, which represents the measure of the central angle x.
--------------
For any triangle, the three angles always add to 180. This means,
x+y+z = 180
72+y+z = 180 .... plug in x = 72
72+y+y = 180 ... recall that y = z
2y+72 = 180
2y = 180-72
2y = 108
y = 108/2
y = 54, which is also the measure of angle z as well
--------------
As a quick check,
x+y+z = 72+54+54 = 180
which helps confirm the answer.

Ruby is saving up to buy a new jacket. She already has $25 and can save an additional $7 per week using money from her after school job. How much total money would Ruby have after 10 weeks of saving? Also, write an expression that represents the amount of money Ruby would have saved in ww weeks.
Total savings after 10 weeks:
Total savings after ww weeks:
From the question;
1) Ruby will save $95 after ten weeks
2) The equation for ww weeks is; S = $25 + ($7 x ww)
What is an equation?
Total savings after 10 weeks:
Ruby saves $7 per week from her after school job, and she already has $25, so her total savings after 10 weeks can be calculated as follows:
Total savings = Initial savings + (Weekly savings x Number of weeks)
Total savings = $25 + ($7 x 10)
Total savings = $25 + $70
Total savings = $95
So, Ruby would have a total of $95 after 10 weeks of saving.
Expression for the amount of money Ruby would have saved in ww weeks:
Let "S" represent the total savings after ww weeks.
Expression: S = $25 + ($7 x ww)
