Hi! First, we multiply both sides by 5, -n/5*5=5*5=-n=25. Second, we divide both sides by -1, -n/-1=25/-1. Therefore, our answer is n=-25

A dog trainer has 104 ft of fencing that will be used to create a rectangular work area for dogs. If the trainer wants to enclos
vova2212 [387]

Answer:

  36 ft by 16 ft

Step-by-step explanation:

To solve this problem, you need to find dimensions of a rectangle such that the perimeter is 104 ft and the area is 576 ft. The perimeter is twice the sum of length and width, so the sum of length and width is 52 ft.

The area is the product of length and width, so if w represents the width, we have ...

  w(52 -w) = 576

  w² -52w = -576 . . . . . eliminate parentheses, multiply by -1

  w² -52w +26² = 26² -576 . . . . . .  complete the square

  (w -26)² = 676 -576 = 100

  w = 26 ±√100 =  {16, 36}

If the width is the short dimension, it is 16 feet. Then the length is 36 feet.

Question 7 of 10
astra-53 [7]

The correct answer is option D which is 0.798

The complete question is given below:-

For an exponential regression equation in the form y=ab^x which of the following values of b will cause y to get smaller as x gets larger?

a.) 1.526

b.) 1.798

c.) 2.526

d.) 0.798

<h3>What is an equation?</h3>

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

Since we know that an exponential function is in the form:y= ab.^x where,

a= Initial value,

b = For growth b is in form (1+r), where r is the rate in decimal form.

b = For decay or regression b is less than 1 and in form (1-r), where r is the rate in decimal form.

Upon looking at our given choices we can see that options a, b and c are in form 1+r, while the choice provided in option d is less than 1 and in form 1-r, therefore, option d is the correct choice.

Therefore the correct answer is option D which is 0.798

suppose that two people standing 3 miles apart both see the burst from a firework display.after a period of time ,the first pers
Marrrta [24]

The fireworks display occur at 550.331 ft

The generic equation for a hyperbola provided by: is the best method for solving the problem in this instance.

\frac{y^{2} }{b^{2} } - \frac{x^{2} }{a^{2} } = 1 -

We presume that the y-axis is where the hyperbola's longer axis lies.

In this instance, the sound traveled a total of 1100 meters, and the value of a can be calculated as follows:

2a = 1100

a = 550ft

Given that the two people are 3 miles apart, we can calculate the value of c in feet as follows:  

1 mile = 5280 feet

∴ 3 miles = 15840 ft = c

And this is how we may determine what b is worth:

b^{2} = c^{2} - a^{2}

b^{2} = 15840^{2} - 550^{2}

b^{2} = 250603100

Our equation is thus given by:

\frac{y^{2} }{250603100 } - \frac{x^{2} }{550^{2} } = 1

And for this case we want to find the value of x when y = 3ft=15840ft and solving for x we get,

\frac{15840^{2} }{250603100 } - \frac{x^{2} }{550^{2} } = 1

\frac{15840^{2} }{250603100 } - 1 = \frac{x^{2} }{550^{2} }

1.001- 1 = \frac{x^{2} }{550^{2} }

0.001 = \frac{x^{2} }{550^{2} }

302865.145= {x^{2}

x = 550.331 ft.

The fireworks display occur at 550.331 ft.
