The linear function that relates the helicopter's elevation (E) to the travel time (t) is:
E = −493t+14787What is a linear function?A linear function is modeled by:
[tex]y = mx + b[/tex]
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0.In this problem:
The helicopter descends at a rate of 493 feet per minute, hence [tex]m = -493[/tex].It flies from an elevation of 14,505 feet to an elevation of 282 feet BELOW sea level, hence the distance it travels in feet is [tex]b = 14505 + 282 = 14787[/tex]Hence, the model is:

How do i write the quotient as a mixed number?
Answer:
divide the numerator by the denomantor
Step-by-step explanation:
A fraction in which the numerator is smaller than the denominator, like 1/3 or 2/5 is called a proper fraction. A fraction in which the numerator is larger than or equal to the denominator, like 5/2, 17/3, or 6/6 is called an improper fraction. (To put it another way, a fraction with a value less than 1 is a proper fraction. A fraction with a value greater than or equal to 1 is an improper fraction.)
As we have shown above, mixed numbers can be written as improper fractions. Similarly, improper fractions can be written as mixed numbers.

What transformation is described by the
notation (x, y) —> x,-y)?
A : translation left 1 unit
B : translation down 1 unit
C : reflection across the x-axis
D : reflection across the y-axis
Answer:
C. reflection across the x-axis
Step-by-step explanation:
When a point is reflected across the x-axis, the x-coordinate stays the same while the y-coordinate turns into its opposite (positive to negative, negative to positive).
As we can see in the notation, the x-coordinate stayed the same while the y-coordinate went from positive to negative, which tells us that this notation is a reflection across the x-axis.

Ms. Smith purchased ½ of a pound of grapes. She would like to make 1/12 of a pound portions for this week’s snacks. How many portions will she be able to make?
Answer:
There is no enough information to determine how many portions she will be able to make.
We need to know how many pounds of grapes will she needs to make a particular pounds portions for the snacks.
For example, if she needs 2 pounds of grapes to make 5 pounds portion for the snacks, and she purchase ½ pounds of grapes, we can determine how many pounds of portions for the snacks she will be able to make with this information.
Using a simple ratio
2:5 = ½:x
2/5 = ½/x
Multiplying both sides by x
(2/5)x = 1/2
Multiplying both sides by 5/2
x = (1/2)×(5/2)
x = 5/4
x = 1¼ pounds
Meaning she will be able to make 1¼ pounds of portion for snacks with ½ pounds of grapes.

A power system will collapse if a ground fault occurs on any two of lines A, B, and C simultaneously. Assume that ground faults on lines A, B, and C are independent and have identical probability of 0.01. Hint: parts (a) and (b), use Bernoulli Trials; part (c), use Bayes Rule. a) What is the probability that the system will collapse
Answer:
0.000298 = 0.0298% probability that the system will collapse
Step-by-step explanation:
Number of possible ways the system can fail:
2 lines from a set of 3 fail, or all three fail.
Two from a set of 3:
Can be A and B, A and C, or B and C. Three possible outcomes then.
The probability of each is:
0.01*0.01*0.99
Two failling, each with 0.01 probability, and 1 working, with 0.99 probability.
All three:
Each with 0.01 probability.
a) What is the probability that the system will collapse
Both cases, so
[tex]p = 3*(0.01)^2*0.99 + (0.01)^3 = 0.000298[/tex]
0.000298 = 0.0298% probability that the system will collapse

divide 49 ÷ 8 = and show your work
Answer:
6
Step-by-step explanation:
Place this digit in the quotient on top of the division symbol. Multiply the newest quotient digit (6) by the divisor 8 . Subtract 48 from 48 . The result of division of 48÷8 48 ÷ 8 is 6
The required, 49 divided by 8 gives 6 as the quotient and 1 as the remainder.
To divide 49 by 8, you can use long division to find the quotient.
Determine how many times the divisor (8) can fit into the new number (49). In this case, 8 goes into 49 six times. Subtract the result (48) from the number you brought down (49). 49 - 48 = 1. Write the result (1) below the line.
6
_______
8 | 49
- 48 (8 times 6)
______
1 (Remaining 1 after subtracting)
Therefore, 49 divided by 8 gives 6 as the quotient and 1 as the remainder.

The perimeter of the parallelogram is of 44 units.
What is the perimeter of a figure?
The perimeter of a figure is given by the sum of all it's outside measures.
In this problem, since it is a parallelogram, we have that:
AD = BC
Hence:
3x - 1 = 2x + 2
x = 3
Hence:
AD = BC = 3x - 1 = 3(3) - 1 = 8
We also have that:
AB = DC
4y - 2 = 2y + 6
2y = 8
y = 4
Then:
AB = DC = 4y - 2 = 4(4) - 2 = 14
Thus, the perimeter is:
2 x (14 + 8) = 44 units.
