1 What is the domain of the following function?
A -4
B 4≤x≤1.5
C -5
D -5≤y≤6
Answers
The domain of the function is -4 ≤ x ≤ 1.5. The correct answer is option B.
What is Domain ?
A domain is the possible independent variable value of a function. In a two dimensional graph, the independent variable is x - axis.
From the given graph, tracing the line of the equation to the x - axis, the independent variable value span from x = -4 to x = 1.5.
So, we can say that the domain of the function is -4 ≤ x ≤ 1.5
Therefore, the correct answer is option B.

The length and width of a rectangle are consecutive integers. The perimeter of the rectangle is 42 inches. Find the length and width of the rectangle.
Answers
Answer:
The length of the rectangle is 11 inches, and the width of the rectangle is 10 inches.
Step-by-step explanation:
Let l be the length of the longer side of the rectangle. Then the width of the rectangle is l-1 inches. Since the perimeter of the rectangle is 42 inches, we have:
2(l + l - 1) = 42
l + l - 1 = 21
2l = 22
l = 11 inches, so l - 1 = 10 inches

Answers
The trail that is closest in length to 10.5 kilometers is Spruce Trail. option D
How to determine the closest trailFrom the information given, we have that;
Oak Trail = 10.653 kilometersMaple Trail = 10.592 kilometersPine Trail = 10.732 kilometersSpruce Trail = 10.484 kilometersThe closest in length would be the trail with the lowest difference;
Oak trail = 10.653 - 10. 5 = 0. 153
Maple Trail = 10.592 - 10. 5 = 0. 092
Pine Trail = 10.732 - 10. 5 = 0. 232
Spruce Trail = 10.484 - 10. 5 = -0. 016
Thus, the trail that is closest in length to 10.5 kilometers is Spruce Trail. option D

Solve using PEMDAS
11²-[3. (8-5)*7-19=
Answers
Step-by-step explanation:
The order of operations is a rule that tells the correct sequence of steps for evaluating a math expression. We can remember the order using PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)
Answer:
39.
Step-by-step explanation:
I say good try to the first guy, but aye, it's not fully answering the question.
PEMDAS is the order you solve all of this in. Parenthesis (), Exponents (^), Multiplication (*), Division (/), Addition (+), and Subtraction (-).
We would solve (8-5) first for 3, since there is no sign between both three's, this will be multiplication.
Next is the exponent, 11^2 is 11*11, which is equal to 121.
121 - 3 * 3 * 7 - 19
Next up is Multiplication. 3 * 3 = 9, and 9 * 7 is 63.
Now our equation is 121 - 63 - 19. There is no Division or addition symbol, so we skip to Subtraction.
121 - 63 = 58, and 58 - 19 = 39.
Your Answer is 39.

Step-by-step explanation:
The value of x is 8.366, y is 4.582 and z is 5.477.
Using Pythagoras theorem in both Triangle as
Triangle 1:
H² = P² + B²
z²= y² + 3²
z² = y² + 9
Triangle 2:
x² = y² + 7²
x² = y² + 49
and, x² = z² - 9 + 49
x² = z² + 40.............(1)
Now, In big Triangle
x² + z² = 10²
x² + z² = 100
Now, from equation (1) we get
z² + 40 + z² = 100
2z² = 60
z² = 30
z = 5.477
and, x²= 30+40 = 70
x= 8.366
and, y²= z² - 9
y² = 21
y= 4.582

Question 3: A family is traveling in their RV all summer. They have several propane tanks on their RV. Propane is safe to use between temperatures of −40° F and 120° F.
Write an inequality to represent the temperatures at which the propane is safe to use.
Answers
The inequality to represent the temperatures at which the propane is safe to use is -40 < x < 120.
It is said that it is safe to use Propane between the temperatures of -40°C and 120°C.
We already know the use of an equality. It makes the values on both sides of it equivalent.
An inequality compares the values on both sides of it. It informs us which one is greater than or less than the other or if they are equal. That is, inequality has a possibility for equality too.
Here the minimum temperature at which propane is safe to use = -40°C
The maximum temperature at which Propane is safe to use = 120°C
We take a variable 'x' to denote the safe temperature of Propane.
Then according to the information, the inequality to represent the temperatures at which the propane is safe to use is,
-40 < x < 120
An inequality is written with the bigger value is in the open end of '<' and the lower value at the other end.

Change the following statement into coordinate points
a)f(-1)=1
b)f(2)=7
c)f(1)=1
d)f(3)=0
Answers
Changing [f(-1) = 1] into coordinate points, we get (x₁, y₁) = (-1, 1),
Changing [f(2) = 7] into coordinate points, we get (x₂, y₂) = (2, 7),
Also, changing [f(1) = 1] into coordinate points, we get (x₃, y₃) = (1, 1),
And finally, changing [f(3) = 0] into coordinate points,
We get (x₄, y₄) = (3, 0).
As per question statement, we are provided with Four separate functions, as follows, [f(-1) = 1], [f(2) = 7], [f(1) = 1] and [f(3) = 0].
We are required to convert the above mentioned functions into coordinate points.
To solve this question, we need to know the standard form of conversion of functions into coordinate points, which goes as [y = f(x)], i.e., the ordinate is a function of the abscissa.
Thus comparing [y = f(x)] to [1 = f(-1)], we get (x, y) = (-1, 1).
Similarly, comparing [y = f(x)] to [7 = f(2)], we get (x, y) = (2, 7),
Comparing [y = f(x)] to [1 = f(-1)], we get (x, y) = (-1, 1),
And finally, comparing [y = f(x)] to [0 = f(3)], we get (x, y) = (3, 0).
