Which phrase describes the end behavior of the graph of (x) = x5 4x4 + 7x2 2?

Which phrase describes the end behavior of the graph of ƒ(x) = –x5 – 4x4 + 7x2 – 2?

Answers

Answer 1

well for end behavior, you simply look at the highest exponent (in this case 5) and look for 2 things:
Is it even or odd? Odd
Is it positive or negative? Negative

Using this we can determine that it is up to the left, and down to the right

Or, for more advanced terms, as x approaches -∞, y approaches ∞, and as x approaches ∞, y approaches -∞

(10^25)-7 is divisible by

a) 2 b)3 c)9 d) both 2 & 3

Answers

The answer is b)3.

If the last digit of a number is divisible by 2, than the number is divisible by 2 (for example, in 828, the last digit is 8 which is divisible by 2 (8/2 = 4), so 828 is also divisible by 2).

If the sum of all the digits of a number is divisible by 3, then the number is divisible by 3 (for example, in 396, the sum of the digits is 18 (3+9+6=18), so 396 is also divisible by 3).

Similarly, if the sum of all the digits of a number is divisible by 9, then the number is divisible by 9.

Now, let's check it out for 10²⁵ - 7. Let's first take simple examples:
10² - 7 = 100 - 7 = 93 (The last digit is not divisible by 2. Also, the sum of the digits is 9+3=12 and it is divisible only by 3, but not by 9).
10³ - 7 = 1000 - 7 = 993 (The last digit is not divisible by 2. Also, the sum of the digits is 9+9+3=21 and it is divisible only by 3, but not by 9).
10⁴ - 7 = 10000- 7 = 993 (The last digit is not divisible by 2. Also, the sum of the digits is 9+9+9+3=30 and it is divisible only by 3, but not by 9).
....
10²⁵-7 =..... There are many zeros, but based on the previous examples, we can make a conclusion that the last digit is not divisible by 2. Also, the sum of the digitsit is divisible only by 3, but not by 9.

Find a possible formula for a fourth degree polynomial g g that has a double zero at 1 1 g(−4)=0 , g(5)=0 , and g(0)=−6

Answers

There's a double zero at 11, so that means (x-11)^2 is a factor

g(-4) = 0 so x+4 = 0 meaning that (x+4) is a factor
g(5) = 0 so x-5 = 0 meaning that (x-5) is a factor

all together, we have

(x-5)*(x+4)*(x-11)^2

let's expand this out

(x-5)*(x+4)*(x-11)^2
(x^2-x-20)*(x^2-22x+121)
x^2(x^2-22x+121) - x(x^2-22x+121) - 20(x^2-22x+121)
x^4-22x^3+121x^2-x^3+22x^2-121x-20x^2+440x-2420
x^4-23x^3+123x^2+319x-2420

This is multiplied by some constant k such that

k*(x^4-23x^3+123x^2+319x-2420) = -6

where plugging in x = 0 leads to -6

Let's plug in x = 0 and find out what happens with k

k*(x^4-23x^3+123x^2+319x-2420)
k*(0^4-23*0^3+123*0^2+319*0-2420)
k*(-2420)
-2420k

So -2420k = -6 leads to k = 3/1210

Therefore, the equation is [tex]y = \frac{3}{1210}(x^4-23x^3+123x^2+319x-2420)[/tex]

The fourth degree polynomial g(x) with a double zero at x=1, zeros at x=-4 and x=5, and satisfying g(0)=-6 is g(x) = 3/10(x-1)²(x+4)(x-5).

A possible formula for a fourth degree polynomial g(x) with specific characteristics. The polynomial must have a double zero at x=1, zeros at x=-4 and x=5, and must satisfy g(0)=-6.

Since the polynomial has a double zero at x=1, we can represent that part of the polynomial as (x-1)². The other two zeros at x=-4 and x=5 give us factors of (x+4) and (x-5) respectively. Multiplying these factors gives us a polynomial that satisfies the zero requirements: (x-1)²(x+4)(x-5).

Now, we need to find the constant k that will make the polynomial satisfy g(0) = -6. We set up the equation using the known factors:
k(x-1)²(x+4)(x-5) and substitute x with 0 to solve for k. This gives us k(0-1)²(0+4)(0-5) = -6. Solving for k, we find k = 3/10.

Therefore, the formula for the polynomial g(x) is g(x) = 3/10(x-1)²(x+4)(x-5).

which fraction is not equivalent to 7/8

a 21/24 b 35/40 c 15/16 d 28/32

Answers

7/8 = 7 divided by 8 = 0.875

21/24 = 21 divided by 24 = 0.875
35/30 = 35 divided by 40 = 0.875
15/16 = 15 divided by 16 = *0.9375*
28/32 = 28 divided by 32 = 0.875

Answer=15/16 is not equivalent to 7/8.

Final answer:

Option c, 15/16, is the correct answer because it cannot be simplified to 7/8, making it not equivalent to 7/8, while the other options are equivalent after simplification.

Explanation:

The question asks us to identify which fraction is not equivalent to 7/8. To determine this, we need to compare each option with 7/8:

Option a: 21/24 can be simplified by dividing the numerator and the denominator by 3, which gives us 7/8, so this option is equivalent.Option b: 35/40 can be simplified by dividing the numerator and the denominator by 5, which gives us 7/8, so this option is equivalent as well.Option c: 15/16 cannot be simplified to 7/8 because when we divide both by their greatest common divisor, we do not get 7/8. Therefore, this fraction is not equivalent to 7/8.Option d: 28/32 can be simplified by dividing the numerator and the denominator by 4, which gives us 7/8, so this option is equivalent.

Hence, the correct answer is option c, which is not equivalent to 7/8.

Answers

this is sort of weird to write without any numbers, but it's not too hard. take your info out of the word problem:

fit fast = fee per class
stepping up = fee per class + monthly fee

now you just change all of that into variables, essentially:

F = cx
S = cx + m

so, fit fast is the cost of classes (c) times the number of classes taken (x). stepping up is the cost of classes times x, PLUS that additional monthly fee (m).

x = -3

r = sqrt(x^2 + y^2)
r = sqrt((-3)^2 + (3*sqrt(3))^2)
r = sqrt(9+27)

r = 6

theta = arctan(y/x)
theta = arctan(3sqrt(3)/(-3))
theta = arctan(-sqrt(3))
theta = -60 degrees which is coterminal to 300 degrees

So the polar form is (r,theta) = (6, 300)

how does sin(-13pi/4) = -5pi/4

we were asked to find the exact value of sin(-13pi/4)
how does sin(-13pi/4) = -5pi/4

we were asked to find the exact value of sin(-13pi/4)

Answers

NOTE: My solution here has +13pi/4 instead of yours as -13pi/4, however, if you just examine this solution, it could help you solve the problem yourself.

13π / 4 needs to be 'reduced' so that we find out where on the Unit Circle you are.

To do this, subtract out 8π / 4 (2π, or a whole Unit Circle) until you can't do it anymore without getting a negative number.

Subtracting out 8π/4 gives you 5π/4.

Sin 5π/4 = -√2 / 2

The reason I chose 8π/4 was because your fraction had 4 in the denominator. If it had, say, 12 in the denominator, the subtraction would have been 24π/12 (still giving 2π, or a whole Unit Circle). Make sense?

The equation sin(-13π/4) = -5π/4 is incorrect.

The correct value for sin(-13π/4) is actually 1/√2 or √2/2, not -5π/4.

Here, we have,

To understand why, let's break down the calculation step by step:

The sine function represents the ratio of the length of the side opposite the angle to the length of the hypotenuse in a right triangle.

In this case, we have an angle of -13π/4.

To find the reference angle,

we can add 2π to -13π/4 to bring it into the standard range of angles:

-13π/4 + 2π = -5π/4

Now, we can find the reference angle of -5π/4 in the unit circle or trigonometric table.

The reference angle of -5π/4 is π/4.

Since sine is positive in the second quadrant,

the value of sin(-5π/4) is the same as sin(π/4), which is 1/√2 or √2/2.

Therefore, the correct exact value of sin(-13π/4) is 1/√2 or √2/2, and not -5π/4.

Square feet! Cubic feet are used for 3D spaces, or volume, which won't be necessary for a 2D surface. Yards are commonly used for distance and perimeter. Square yards would be much too long for something such as tiling on a bathroom floor. Hope this helps.

Answer:

Step-by-step explanation:

In order to take the measurements, he should use the square feet unit of measure.

As, the cubic feet also known as unit of volume can be defined as the volume of the cube with sides of one foot in length. Since, the bathroom is two dimensional therefore, cubic feet can't be used.

Yards are basically a unit of length use to measure length and perimeter and square yards are used in measuring the long space and the bathroom is bit too small for it.

Therefore, square feet should be used to measure.

A. $18
B. $15
C. $25
D. $10
<33 please help
...?

Answers

Let c is the cost of renting a canoe and t is the cost of renting inner tubes.

For the girls,
2c + 3t = 80
For the boys,
c + 7t = 95

Solving the system of equations, multiply the second equation by 2 and subtract them.

2c + 3t = 80
2c + 14t = 190
---------------
11t = 110
t = 10

Substitute t to either equations,
c = 95 - 7t
c = 95 - 7(10)
c = 25

Therefore, one canoe costs $25 (C.)

The cost to rent 1 canoe from the rent made by the group of the girls and boys is $25.

What are word problems?

Word problems are a mathematical interpretation by using variables, numbers, and arithmetic operations to solve real-life problems.

From the given information:

The group of girls: 2c + 3t = 80 --- (1)The group of boys: 1c + 7t = 95 ---- (2)

Now, we can have a system of equations, and we can solve for the number of canoes and the inner tubes rented.

Using Elimination method:

2c + 3t = 80 --- × (1)

c + 7t = 95 --- × (2)

2c + 3t = 80

-2c + 14t = 190

0 + -11t = -110

-11t = -110

t = -110/-11

t = 10

From equation (1)

2c + 3t = 80

2c + 3(10) = 80

2c + 30 = 80

2c = 80 - 30

2c = 50

c = 50/2

c = 25

Therefore, we can conclude that the cost of the rent of 1 canoe is $25.
