Which is a possible turning point for the continuous function
f(x)?
(-3,-4)
(-2,-1)
(0,-5)
(1,8)
Answer:
B. (-2,-1)
Step-by-step explanation:
A continuous function is one that do not discontinue, and a little change in its input has no effect on its result. This is one major difference between continuous and discontinuous functions. Both functions has major applications in calculus.
The turning point of a function can be obtained by determining where it is increasing or decreasing.
In the given question, though there is no detailed information about the continuous function, but the probable turning point is (-2, -1).

Answer:
Attachment 1 :- x = 3/2
Attachment 2 :- m + r = 154°
Step-by-step explanation:
Attachment 1 :-
[tex]9^(^2^-^x^) = 3\\=> 3^2^(^2^-^x^) = 3\\[/tex]
As the base 3 is same on both the sides , cancel the base 3 from both left & right side of eqn. After that we will get:-
[tex]2(2 - x) = 1\\=> 2 - x =\frac{1}{2} \\=> x = 2 - \frac{1}{2} = \frac{3}{2}[/tex]
Attachment 2 :-
PQR is a straight line . It's given that m + n = 110°
But we know that m + n + r = 180° ..............eqn.1
So substituting the value of m+n in eqn.1 gives :-
m+n+r = 180°
=> r + 110° = 180°
=> r = 180° - 110°
= 70°
It's also given that n+r = 96°
So putting the value of r in the above gives ,
n+r = 96°
=> n + 70° =96°
=> n = 96° - 70°
= 26°
Putting the value of n in eqn.1 gives
m + n = 110°
=> m + 26° = 110°
=> m = 110° - 26°
= 84°
So m + r = 84° + 70° = 154°
At the movie theatre, child admission is $6.40 and adult admission is $9.50. On Sunday, 165 tickets were sold for a total sales of $1266.80. How many adult tickets were sold that day?
Answer:
68Step-by-step explanation:
1. Define unknowns:
x - number of adult tickets ($9.50 each)y - number of child tickets ($6.40 each)2. Make system of equations:
[tex]x+y=165[/tex] [tex]9.5x+6.4y=1266.8[/tex]3. Multiply both sides of first equation by 6.4:
[tex]6.4x+6.4y=1056[/tex] [tex]9.5x+6.4y=1266.8[/tex]4. Subtract first equation from second one:
[tex](9.5x-6.4x)+(6.4y-6.4y)=1266.8-1056[/tex] [tex]3.1x=210.8[/tex] [tex]x=68[/tex]plssssss answer quick Hudson bought a plant and planted it in a pot near a window in his house. The initial height of the plant was 8 inches and it grew at a rate of 3 inches per month. Write an equation for H,H, in terms of t,t, representing the height, in inches, of the plant tt months after Hudson bought the plant.
Answer:
H = 8 + 3t
Step-by-step explanation:
H = height
t = time in months
H = 8 + 3t
H is the height at and given time. 8 is the initial height and since it grows 3 in a month it would be 3 times how ever many months have passed.
For example after 6 months
t = 6
H = 8 + 3 (6)
H = 8 + 18
H = 26in
If I had 39inches and 28inches how many inches and all
Answer:
67 inches
Step-by-step explanation:
Since the question is asking how many inches total do you have, we need to add up the 2 values given:
39 inches + 28 inches = 67 inches.
We can convert this to feet by dividing by 12:
67 in /12 in/ft ≈ a little over 5 and a half feet

At 5:00 a.M., a parking lot had 16 cars already parked in it. Throughout the course of the day, 48 more cars entered and parked in the parking lot. Which situation would result in a difference of 0 for the cars exiting the lot for the day?
Answer:
The situation is that; the parking lot has 64 cars at the end of the day
Step-by-step explanation:
Given
Initial Number of cars = 16
Additional Cars = 48
Required
Determine the situation for the day
From the question, we understand that no car left the park;
This implies that
[tex]Number\ of\ cars = Initial\ Cars + Additional\ Cars[/tex]
[tex]Number\ of\ cars = 16 + 48[/tex]
[tex]Number\ of\ cars = 64[/tex]
So, the situation is that; the parking lot has 64 cars at the end of the day
Mya has an exercise ball in the shape of the sphere shown below.She wants to increase the weight of the ball by filling it with water. Which is closest to the amount of water in cubic inches,that Mya's exercise ball will hold if it is completely full?
Answer: Volume of a sphere = 4/3 * pi * r^3 r = radius of sphere pi~ 3.14
Step-by-step explanation: If you use the radius in inches, your result will be in cubic inches (in^3)
The amount of water in cubic inches, that Mya's exercise ball will hold is 904.779 in³.
What is the volume of a sphere?The volume of a sphere is the volume of space occupied by a sphere. It is given by the formula:
[tex]\text{Volume of Sphere} = \dfrac{4}{3}\pi r^3[/tex]
As it is given that the diameter of Mya's ball is 12 inches, also we know that the volume of a sphere is given by the formula,
[tex]\text{Volume of Sphere} = \dfrac{4}{3}\pi r^3[/tex]
As we know that the diameter of Mya's ball is 12 inches, therefore, the radius of Mya's ball can be written as,
[tex]\rm Radius = \dfrac{Diameter}{2} = \dfrac{12\ in}{2} = 6\ in.[/tex]
Now, if we substitute the value of the radius of Mya's ball in the formula of the volume of the ball,
[tex]\rm \text{Volume of Ball} = \dfrac{4}{3}\times \pi \times 6^3 = 904.779\ in^3[/tex]
Hence, the amount of water in cubic inches, that Mya's exercise ball will hold is 904.779 in³.

-8=-10x + 5y
Answer:
-8/5 + 2x = y
Step-by-step explanation:
-8=-10x + 5y

how do i find the Domain and Range in Inequality form
Answer:
Domain is the set of all x values, the independent quantity, for which the function f(x) exists or is defined.
Step-by-step explanation:
i just graphed it
Answer:
Domain:
[tex]x\in\mathbb{R}[/tex]
Range:
[tex]y\geq -5[/tex]
Step-by-step explanation:
The domain is the span of x-values covered by the graph, and the range is the span of y-values covered by the graph.
From the graph, we can see that the x-values covered by the graph will extend infinitely in both directions. Therefore, the domain of the graph is all real numbers.
We can't write this as an inequality, but we can write:
[tex]x\in\mathbb{R}[/tex]
For the range, we can see from the graph that the lowest y-value is y=-5. The graph doesn't go any lower than that. However, the graph will also cover all values greater than -5. Therefore, the range of the graph is all values greater than or equal to -5. In an inequality, this is:
[tex]y\geq -5[/tex]

A playground measures 300 m × 170 m.Find the cost of planting grass on this at the rate of Rs 80 per hectare.
To find the cost of planting grass , we have to find area of the field.
Area of field = Length × Breadth
[tex]{= 300×170}[/tex]
[tex]{=51000 sq. m}[/tex]
Now convert into hectare.
1 hectare = 10000m sq.
51000 / 10000
So area field = 5.1 hectare sq.
Now cost = 5.1 x 0.80 p

How much will fertilizer cost for a field 725 feet by 1,021 feet if one bag covers 10,000 square feet and costs $12.97 per bag?
Answer:
$9600.72
Step-by-step explanation:
Area of the field = length × width
Length = 1,021 feet
Width= 725 feet
Area of the field = length × width
= 1,021 feet × 725 feet
= 740,225 square feet
One bag covers 1000 square feet
There are 740,225 square feet
Find the number of bags that will cover the total of 740,225 square feet
Total bags = 740,225 / 10000
=740.225 bags
A bag cost $12.97
Total cost of 740.225 bags= 740.225 × 12.97
= $9600. 71825
Approximately
