What can you say about the end behavior of the function f(x) = -4x6+6x2 -52 ?
A. F(x)is an even function so both ends of the graph go in the same
direction.
B. f(x) is an even function so both ends of the graph go in opposite
directions
O C. The leading coefficient is negative so the left end of the graph
goes up.
D. The leading coefficient is negative so the left end of the graph
goes down
Answer:
A. F(x)is an even function so both ends of the graph go in the same direction.
D. The leading coefficient is negative so the left end of the graph goes down.
Step-by-step explanation:
Even function:
For every value of x, f(x) = f(-x)
In this question:
We are given the following function:
[tex]f(x) = -4x^6 + 6x^2 - 52[/tex]
Testing if it is even:
[tex]f(1) = -4(1)^6 + 6(1)^2 - 52 = -4 + 6 - 52 = -50[/tex]
[tex]f(-1) = -4(-1)^6 + 6(-1)^2 - 52 = -4 + 6 - 52 = -50[/tex]
Since f(1) = f(-1), it is even.
Since it is even, both ends of the graph go in the same direction, so option A is correct, while option B is wrong.
Options C and D:
The leading coefficient, is -4(which multiplies x with the highest exponent). Since it is negative, it goes to negative infinity as x increases, that is, the left end goes down, and option D is correct while C is not.

an object is launched at 4 ft./s from 88 foot tall platform the objects height H in feet after T seconds is given by the equation H=-16T^2+8t+80 when does the object strike the ground
Answer:
1.5seconds
Step-by-step explanation:
When the ball hits the ground, the height is equal to zero. So find t when H=0:
H=16t²+8t+80
0=16t²+8t+80
0=2t²+t+10
0=(2t-3)(t+2)
So (2t-3)=0, or (t+2)=0
So t=1.5 or t=-2. Time can't be negative though, so we take our answer as 1.5seconds

What is the surface area in square centimeters of the figure shown below?
11 cm
6 cm
4 cm
Answer:
268 cm²
Step-by-step explanation:
Surface area = (front + back + left side + right side + top + bottom) areas
since pairs of areas are the same (front back, left rigth, top bottom)
Surface area = (2 · front + 2 · left side + 2· top) areas
= 2 · 11 · 4 + 2 · 11 · 6 + 2 · 4 · 6
= 268 cm²
A survey of Mrs. Ramirez's students showed that 30
students will have pizza fonlunch, 17 will have macaroni
and cheese, 12 will have a hamburger, and 5 will have
chicken fingers. Suppose Mrs. Ramirez surveys all 1 200
students in the school. How many students can she
expect to choose hamburgers for
Hunch?
Answer: 480
Step-by-step explanation:
We can create a ratio for this!
We have:
[tex]\frac{number of hamburgers}{total students}[/tex]= [tex]\frac{new number of hamburgers}{new number of students}[/tex]
We can use substitution to input the information we already know:
[tex]\frac{12}{30}[/tex] = [tex]\frac{x}{1200}[/tex]
Using cross multiplication, we get:
1 200(12) = 30x
14,400 = 30x
[tex]\frac{14,400}{30}[/tex]=[tex]\frac{30x}{30}[/tex]
x = 480
Hope this helps! :)
The number of students expect to have hamburgers for lunch is 225 students.
What is a word problem?
A word problem is a verbal description of a problem situation. It consists of few sentences describing a 'real-life' scenario where a problem needs to be solved by way of a mathematical calculation.
For the given situation,
Mrs. Ramirez's survey on students
Number of students have pizza = 30
Number of students have macaroni and cheese = 17
Number of students have a hamburger = 12
Number of students have chicken fingers = 5
Total number of students = 64.
Now, Mrs. Ramirez surveys all 1 200 students.
Then number of students expect to choose hamburgers for lunch can be found by,
[tex]\frac{Number of students have hamburgers}{Total number of students} = \frac{Number of students expect to have hamburgers}{ Total number of students}[/tex]
Let x be the number of students expect to have hamburgers.
⇒ [tex]\frac{12}{64}=\frac{x}{1200}[/tex]
⇒ [tex]x=\frac{(12)(1200)}{64}[/tex]
⇒ [tex]x=225[/tex]
Hence we can conclude that the number of students expect to have hamburgers for lunch is 225 students.

Hi
Let's call X the amount in the beginning.
we have X*1.03^6 = 1819.77
X = 1819.77 / 1.03^6
X ≈ 1524.03

Find the area of the following
trapezoid:
8 cm
5 cm
4 cm
16 cm
A = [?] cm2
PLEASE HELP
Answer:
48 cm²
Step-by-step explanation:
Area of trapezoid = [tex]\frac{a + b}{2}[/tex] × h
Area = (8 + 16)/2 x 4
Area = 24/2 x 4
Area = 12 x 4
Area = 48 cm²
Given = x= [b a 4 a ] Y =[c d a b] and z = [a c 16 b] What is Y if x-2y=Z?
Answer:
a [2, -4, -6, -2]
Step-by-step explanation:
The calculated value of the matrix Y is : Y = [tex]\left[\begin{array}{ccc}2&-4\\-2&-6\end{array}\right][/tex]
What is matrix?In mathematics, a matrix is a rectangular array or table of numbers, symbols, or expressions, arranged in rows and columns, which is used to represent a mathematical object or a property of such an object.
Here, we have,
Calculating the matrix Y
From the question, we have the following parameters that can be used in our computation:
Given that
X - 2Y = Z
So, we have
b - 2c = a
a - 2d = c
4 - 2a = 16
a - 2b = b
So, we have
4 - 2a = 16
-2a = 12
a = -6
Next, we have
a - 2b = b
-6 - 2b = b
3b = -6
b = -2
Next, we have
b - 2c = a
-2 - 2c = -6
-2c = -4
c = 2
Lastly. we have
a - 2d = c
-6 - 2d = 2
-2d = 8
d = -4
The matrix Y is given as: Y =[c d a b]
So, we have
Y = [tex]\left[\begin{array}{ccc}2&-4\\-2&-6\end{array}\right][/tex]

In a triangle, the sum of the lengths of the
two shorter sides is 13 inches. What do
you know about the length of the third
side?
Answer:
The length of the third side is less than 13.
Step-by-step explanation:
In any given triangle the sum of any two sides is longer than the length of the third side.
This means that the length of the third side has to be less than 13, since that is the sum of the lengths of the two shorter sides.
Find the missing lengths!!!!!!!
