Answer:

x = 0,6

Step-by-step explanation:

Move all terms to the left side and set equal to zero. Then set each factor equal to zero.

Answer:

The answer I got is x=0 or x=6

Answer:

the answer is 12-18

it's because 12 can't go in 18

so we minus 18 from 12 which is 6

Then we add the minus sign

Answer:

18.9

Step-by-step explanation:

361-4 = 357

the root of 357 is 18.9 when rounded

Answer: [tex](0,0), (3,-27)[/tex]

Step-by-step explanation:

Given

Curve is [tex]y=x^4-4x^3[/tex]

The stationary point on a differentiable function is the points where the differentiation of the function is zero i.e. slope is zero at that point.

Differentiate the curve [tex]f(x)=x^4-4x^3[/tex]

[tex]\Rightarrow f'(x)=4x^3-12x^2[/tex]

Equate it to zero

[tex]\Rightarrow 4x^3-12x^2=0\\\Rightarrow 4x^2(x-3)=0\\\Rightarrow x=0,0,3[/tex]

Put [tex]x=0,3[/tex] in the function [tex]f(x)=x^4-4x^3[/tex]

[tex]\Rightarrow f(0)=0\\\Rightarrow f(3)=3^4-4(3)^3\\\Rightarrow f(3)=81-108\\\Rightarrow f(3)=-27[/tex]

Therefore, the stationary points are [tex](0,0), (3,-27)[/tex]

Answer:

48

Step-by-step explanation:

5 songs would equal 12 minutes, right?

5 times what equals 20? It's 4, so you take 12 times 4 since there'd be 4 times as many songs. So, to listen to 20 songs it'd take 48 minutes.

Answer:

457 pesos

Step-by-step explanation:

From the above question, we are told that:

David bought 23 pens and 15 pencils.

Each pen = 14 pesos

Each pencil = 9 pesos

The amount of money David spent in total =

(23 × 14 pesos) + (15 × 9 pesos)

= 322 pesos + 135 pesos

= 457 pesos

Therefore, David spent in total 457 pesos

Answer:

1 and to find a unit fraction of an amount, divide the amount by the denominator of the fraction. For example to find 1/3 of 18, divide 18 by 3. 18 ÷ 3 = 6 and so, one third of 18 is 6. /3 is a unit fraction with a denominator of 3.

Answer:

If Sandy bought a soft drink for 2 dollars that's 2 dollars subtracted from the total of $12.00 spent

If we have 10 dollars and bought 5 candy bars we would divide so 10 divided by 5 = 2 so each candy bar costed $2 dollars

Answer:

$156

Step-by-step explanation:

First you must find out the number of dollars Prasad receives per hour.

Since he earns $195 in 15 hours we can do 195/15 = 13 to find out the amount of dollars he earns per hour which is $13.

Next we must find out how much money he receives when he work for 12 hours so we simply do 13 (payment per hour) * 12 (amount of hours he works) which will give us $156!

This makes sense cuz 156 is a little bit less than 195 and ofc 12 is a little bit less than 15!

Prasad earn $156 next week if he is scheduled to work 12 hours

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.

Prasad worked 15 hours this week and earned $195

We have to find the amount earned by prasad for work 12 hours

Let us form an proportional equation.

Let x be the amount earned for 12 hours

15/195 = 12/x

Apply cross multiplication

15x=195(12)

15x=2340

Divide both sides by 15

x=2340/15

x=156

Hence, Prasad earn $156 next week if he is scheduled to work 12 hours

So just multiply $55,000 by 0.15.

After multiplying, you should get 8250.

So 8250 is your answer

Answer:

Step-by-step explanation:

Check for continuity by evaluating 2^x and -x^2 - 4x + 1 at the break point x = 0:  2^0 is 1 and -x^2 - 4x + 1 is also 1, so these two functions approach the same value as x approaches 0.

Now do the same thing with

-x^2 - 4x + 1 and (1/2)x + 3 at x = 2; the first comes out to -11 and the second to 4.  Thus, this function is not continuous at x = 2.  

We must reject statement A.

Statement B:  as x increases without bound, (1/2)x + 3 also increases without bound.  This statement is true.

Statement C:  False, because the quadratic -x^2 - 4x + 1 has a maximum at

x = -b/[2a], or x = -(-4)/[-2], or x = -2

Statement D:  True:  there are no limitations on the values of the input, x.

The statement B is as x approaches positive infinity f(x) approaches positive infinity is true

A point or level beyond which something does not or may not extend or pass.

We have to check for continuity by evaluating [tex]2^x[/tex] and [tex]-x^2 - 4x + 1[/tex]

at the break point x = 0

[tex]2^0[/tex]is 1 and [tex]-x^2 - 4x + 1[/tex] is also 1,

So these two functions approach the same value as x approaches 0.

Now do the same thing with

[tex]-x^2 - 4x + 1[/tex]and [tex](1/2)x + 3[/tex] at x = 2;

The first comes out to -11 and the second to 4.  

Thus, this function is not continuous at x = 2.  

We must reject statement A.

for B we have as x increases without bound,

[tex](1/2)x + 3[/tex]

also increases without bound.  

Therefore the statement B is true statement.

Statement C is  False,

because the quadratic[tex]-x^2 - 4x + 1[/tex] has a maximum at

[tex]x = -b/[2a],[/tex]

[tex]x = -(-4)/[-2],[/tex]

[tex]x=-2[/tex]

There are no limitations on the values of the input, x.

D is also false negative number are in real numbers.

Therefore,the statement B is as x approaches positive infinity f(x) approaches positive infinity is true
