Answer:

f(x) = (x + 4)(x - 4)(x + 3)

The other zeros of the function are at 4 and -3.

Step-by-step explanation:

Given function is f(x) = x³ + 3x² - 16x - 48.

Now, given that - 4 is a zero of the given function.

So, the function has a factor equals to (x + 4).  

Now, f(x) = x³ + 3x² - 16x - 48

⇒ f(x) = x³ + 4x² - x² - 4x - 12x - 48

⇒ f(x) = x²(x + 4) - x(x + 4) - 12(x + 4)

⇒ f(x) = (x + 4)(x² - x - 12)

⇒ f(x) = (x + 4)(x - 4)(x + 3)

Therefore, the other zeros of the function are at 4 and -3. (Answer)

Answer:

error pecentage is 5.5% i think because 1.8 divde by 32.7 is 0.5504... * 100 is 5.504

Step-by-step explanation:

The percent error in Charlie's guess regarding his dog's weight is 5.5%, calculated using the difference between the actual and estimated values divided by the actual value, times 100%.

To calculate the percent error in Charlie's guess, we use the formula for percent error which is:

Percent Error = (|Actual Value - Estimated Value| / Actual Value) × 100%

Substitute the values into the formula:

Percent Error = (|32.7 - 34.5| / 32.7) × 100%

Percent Error = (1.8 / 32.7) × 100%

Percent Error = 0.054983922826 × 100%

Percent Error = 5.5% (rounded to the nearest tenth)

Therefore, the percent error in Charlie's guess is 5.5%.

Answer:

[tex]a=15[/tex]

[tex]b=\frac{1}{3}[/tex]

Step-by-step explanation:

we have an exponential function of the form

[tex]y=a(b^x)[/tex]

where

a is the initial value or y-intercept

b is the base

Looking at the graph

we can see the ordered pairs (0,15) and (1,5)

(0,15) ---> y-intercept

so

The value of a is equal to

[tex]a=15[/tex]

substitute

[tex]y=15(b^x)[/tex]

with the point (1,5) find the value of b

For x=1, y=5

substitute in the exponential function

[tex]5=15(b^1)[/tex]

solve for b

[tex]5=15(b)[/tex]

[tex]b=\frac{1}{3}[/tex]

therefore

The exponential function is

[tex]y=15(\frac{1}{3}^x)[/tex]

Final answer:

The student's question involving a system of equations can be solved to find that the two numbers are 17 and -5. By setting up a system of equations based on the given conditions and solving it using the elimination method, we obtain the values for the two unknown numbers.

Explanation:

System of Equations to Find Two Numbers

Let's define the first number as x and the second number as y. The problem states that x plus twice y equals 7 and twice x plus y equals 29. These statements can be turned into a system of linear equations:

x + 2y = 7

2x + y = 29

Using the substitution or elimination method, we can solve these equations for x and y. First, multiply the first equation by 2 to align the coefficients of x:

(2)(x) + (2)(2y) = (2)(7)

The equations now become:

2x + 4y = 14

2x + y = 29

Subtracting the second equation from the first gives us:

3y = -15

Divide both sides of this new equation by 3 to get the value of y:

y = -5

Now that we have a value for y, substitute it back into one of the original equations to find x:

x + 2(-5) = 7

x - 10 = 7

x = 17

The two numbers that solve the system are x = 17 and y = -5.

4x+8=7.8+5x

Subtract 4x from both sides:

8 = 7.8 +x

Subtract 7.8 from both sides:

x = 0.2

Answer:

The value of positive integers are 21.22 and 12.11

Step-by-step explanation:

Given as :

The sum of squares of two integer = 698

Let The one positive integer be x

And The other positive integer be y

According to question

one positive integer = 3 less than twice the other positive integer

So, x = 2 × y - 3

I.e x = 2 y - 3

And x²  +  y² = 698

So, Put the value of x

I.e  ( 2 y - 3 )² +  y² = 698

or, 4 y² + 9 - 12 y +  y² = 698

Or, 5 y² - 3 y - 698 = 0

Now solving this quadratic equation

y = [tex]\frac{-b\pm \sqrt{b^{2}-4\times a\times c}}{2\times a}[/tex]

Or, y = [tex]\frac{3\pm \sqrt{-3^{2}-4\times 5\times -698}}{2\times 5}[/tex]

Or, y = [tex]\frac{3\pm \sqrt{13969}}{10}[/tex]

Or, y = [tex]\frac{3\pm 118.19}{10}[/tex]

∴ y = 12.11 , - 11.51

So , The value of y = 12.11

And the value of x = 2 × 12.11 - 3

I.e x = 21.22

Hence The value of positive integers are 21.22 and 12.11 Answer

To find the two integers, we can set up two equations based on the given information. By substituting the value of x from the first equation into the second equation, we can solve for y. Then, substituting the value of y back into the first equation, we can find the value of x.

To solve this problem, we can set up two equations based on the given information. Let's say the first integer is x and the second integer is y. We are given that x is 3 less than twice y, so we can write the equation: x = 2y - 3. We also know that the sum of their squares is 698, so the equation becomes x^2 + y^2 = 698. Now we can substitute the value of x from the first equation into the second equation and solve for y.

Substituting x = 2y - 3 into the equation x^2 + y^2 = 698, we get (2y - 3)^2 + y^2 = 698. Expanding this equation, we get 4y^2 - 12y + 9 + y^2 = 698. Combining like terms, we have 5y^2 - 12y + 9 = 698. Rearranging this equation and simplifying, we get 5y^2 - 12y - 689 = 0. Now we can solve this quadratic equation to find the value of y.

Using the quadratic formula, y = (-(-12) ± sqrt((-12)^2 - 4(5)(-689))) / (2(5)). Simplifying the equation further, we have y = (12 ± sqrt(144 + 13780)) / 10. Taking the positive value, y = (12 + sqrt(13924)) / 10. Evaluating this expression, we find y ≈ 9.7394. Now we can substitute this value back into the first equation to find x.

Using x = 2y - 3, we have x = 2(9.7394) - 3. Simplifying this equation, we get x ≈ 16.4788. Therefore, the two integers are approximately 16.4788 and 9.7394.

Answer:9

Step-by-step explanation: First you add the 3x to both sides(the -4x and the -3x) and then you get 15-1x=6. Next you subtract 15 from 15 and 6, so you get -1x=-9. So then you divide both sides by -1 (do -1x over -1 equals -9 over -1). Last you do the dividing and you get x=9.

Isolate the variable x by moving terms involving x to one side and constants to the other side. Simplify the equation step-by-step to find that x = 9.

To solve the equation 15 - 4x = 6 - 3x, we need to isolate the variable x. Follow these steps:

Therefore, the solution to the equation 15 - 4x = 6 - 3x is x = 9.

Answer:

- 0.183

Step-by-step explanation:

Given that [tex]\sin \theta = \frac{1}{3}[/tex]

and [tex]\frac{\pi }{2} < \theta  < \pi[/tex]

We have to find the exact value of [tex]\sin (\theta + \frac{\pi }{6} )[/tex].

Now, [tex]\sin \theta = \frac{1}{3}[/tex]

⇒ [tex]\theta = \sin ^{-1} (\frac{1}{3} ) = 19.47[/tex]

Now, since  [tex]\frac{\pi }{2} < \theta  < \pi[/tex],

So, [tex]\theta  = 180 - 19.47 = 160.53[/tex]

{Since [tex]\sin \theta = \sin (180 - \theta)[/tex]

Now, [tex]\theta + \frac{\pi }{6} = 160.53 + 30 = 190.52[/tex]

Hence, [tex]\sin (\theta + \frac{\pi }{6} )[/tex].

= [tex]\sin 190.52[/tex]

Final answer:

It will take approximately 13.6 weeks for the stock's price to reach $20.00 per share.

Explanation:

To determine the number of weeks it will take for the stock's price to reach $20.00 per share, we need to find the number of weeks it will take for the price to decrease from $62.50 to $20.00. Since the price is declining at a rate of 5% per week, we can set up an equation:

$62.50 - ($62.50  imes 0.05  imes  ext{number of weeks}) = $20.00

Simplifying the equation, we have:

$62.50 - (0.05  imes 62.50  imes  ext{number of weeks}) = $20.00

$42.50 = (0.05  imes 62.50  imes  ext{number of weeks})

Dividing both sides by 0.05 and 62.50, we get:

ext{number of weeks} =  rac{42.50}{0.05  imes 62.50}

Calculating this, we find that it will take approximately 13.6 weeks for the stock's price to reach $20.00 per share.

Answer:

The second city is 54 miles behind the first city

Step-by-step explanation:

The first bus is assumed to go ahead of the second bus and is moving at 54 mph. The second bus is moving at a speed such as 54 mph is 60% (0.6) of its speed.  

The speed of the second bus is then 54/0.6 = 90 mph

When 1 and a half hour has passed, the first bus has moved a distance of

[tex]X_1=54\times 1.5[/tex] = 81 miles

The second bus (behind the first bus) has moved

[tex]X_2=90\times 1.5[/tex] = 135 miles

The problem states they both meet in that time, it can only be possible if the second bus departed a distance 135 - 81 = 54 miles behind the first city

So, the second city is 54 miles behind the first city

356,864 × −194,758 = negative sign answer

Answer:

Divide by 13, you will get 10x - 1

To factor the expression 130x - 13, find the greatest common factor, which is 13, and factor it out. The factored form is 13(10x - 1).

To factor the expression 130x - 13, you need to look for a common factor in both terms. In this case, both terms can be divided by 13, which is the greatest common factor of the two numbers. By factoring out 13, you get:

13(10x - 1)

This process is known as factoring by common factor or GCF factoring. It simplifies the expression to a product of a constant (13) and a binomial (10x - 1). This method is very useful in solving equations, simplifying expressions, and can be a first step in more complex factoring processes.
