Answer:

x=0   x=7

Step-by-step explanation:

A(x) = x(x-7)

Set equal to zero

x(x-7) =0

Using the zero product property

x=0     x-7 =0

x=0   x=7

Answer:

2.54648ft.

Step-by-step explanation:

r=8/[tex]\pi[/tex](ft.) therefore, the radius of the circle when its circumference is 16 feet is r≈2.54648ft.

Answer:

r =8

Step-by-step explanation:

Therefore,  C = π d .

We know that the circumference,  C , is  16 π , so we can say that:  

16 π = π d

We can divide both sides by  π  to see that  16 = d .

We now know that the diameter of the circle is  16 .

We also know that the diameter has twice the length of the radius.

In equation form:  2 r = d

 2 r = 16

r = 8

Answer:

No options given. But there are two methods of adding polynomials; The horizontal method, and the vertical method.

Step-by-step explanation:

The options are not stated here. However, there are two methods of adding polynomials; The horizontal method, and the vertical method.

Example: Suppose we want to add the polynomials (3x³ + 5x² + 56) + (16x² + 3x) + (4x³ + 4)

Horizontal method

(3x³ + 5x² + 56) + (16x² + 3x) + (4x³ + 4)

First collect the like terms

3x³ + 4x³ + 5x² + 16x² + 3x + 56 + 4

= 7x³ + 21x² + 3x + 60

Vertical method

3x³ + 5x² +...........56

+ ......16x² + 3x

4x³ +...................... 4

...................................................

7x³ + 21x² + 3x + 60

These two methods both yield the same results.

Answer: decrease

Step-by-step explanation:Accounts payable are what the business owes. By paying off accounts payable, the liabilities are decreasing and the assets are also decreasing (because they use assets/cash to pay off the liabilities, so they have less now).

Answer:

The payment of accounts payable would decrease both assets and liabilities.

Accounts payable (AP) refers to a record inside the overall record that addresses an organization's commitment to take care of a momentary obligation to its leasers or providers. One more typical use of it alludes to the business office or division that is answerable for making installments owed by the organization to providers and different leasers.

In the event that AP increases over an earlier period, that implies the organization is purchasing more services and products on credit, instead of paying cash. In case an organization's AP decreases, it implies the organization is paying on its earlier period obligations at a quicker rate than it is buying new things using credit. And, the thing people or business uses to pay accounts payable in cash, which is an asset. So, basically, when you pay accounts payable, both your assets and liabilities will decrease.

Answer:

Step-by-step explanation:

2x + 5y = 19

x - 2y = -4

Multiply the second equation by 2

2x - 4y = -8

Now we have:

2x + 5y = 19

2x - 4y = -8

Subtract the second eq from the first to get:

9y = 27

/ 9

y = 3

Now substitute this value into one of the first equations

x - 2(3) = -4

x - 6 = -4

x = 2

Thus, your answer would be option B

Answer:

a-135 hot dogs and 245 sodas were sold.

Step-by-step explanation:

Our equations are:

1.25h + 0.75s = 352.50

h + s = 380

Let's use substitution to solve for this system. In the second equation, let's write h in terms of s:

h + s = 380

h = 380 - s

Now, let's plug in 380 - s for h in the first equation:

1.25h + 0.75s = 352.50

1.25(380 - s) + 0.75s = 352.50

We can now solve for s fairly easily:

1.25(380 - s) + 0.75s = 352.50

475 - 1.25s + 0.75s = 352.50

0.5s = 122.5

s = 245 sodas

We can already see which answer choice will match: A, and that is our answer.

Answer:

a-135 hot dogs and 245 sodas were sold.

Step-by-step explanation:

1.25h + 0.75s = 352.50

h + s = 380

h = 380 - s

1.25(380- s) + 0.75s= 352.50

475 - 1.25s + 0.75s = 352.50

122.5 = 0.5s

s = 245

h = 380 - 245

h = 135

Answer:

x=30

Step-by-step explanation:

you distribute the negative to 2x and 19

3x+4-2x-19=15

then you combine like terms

x-15=15

you add 15 to both sides

x=30

Answer:

x = 20

Step-by-step explanation:

We are given the equation ( 3x + 4 ) – ( 2x + 9 ) = 15;

( 3x + 4 ) - ( 2x + 9 ) = 15 ⇒ Take ( ) out, through distribution of - 1,

3x + 4 - 2x - 9 = 15 ⇒ Subtract 4 from either side,

3x - 2x - 9 = 11 ⇒ Combine like terms,

x - 9 = 11 ⇒ Add 9 on either side,

Solution; x = 20

Answer:

Correct option: fourth one -> y = 6(1/3)^x

Step-by-step explanation:

A decay curve is produced by an exponencial function with a rate lesser than 1 and greater than 0. This way, we have an exponencial function where the values of y decrease when the values of x increase.

The first equation is a linear equation.

The second and third equations are exponencial equations, but with a rate bigger than 1

The fourth equation is an exponencial equation with a rate lesser than 1 and greater than 0, so this equation will produce a decay curve.

Answer:

116.62 yards

Step-by-step explanation:

information that we have about the soccer field:

length: [tex]l=100yards[/tex]

width: [tex]w=60yards[/tex]

the line that crosses from one corner to another is the hypotenuse of a right triangle that is formed with the sides [tex]l[/tex] and [tex]w[/tex].

So if we call this distance [tex]h[/tex], by the Pythagorean theorem we will obtain that:

[tex]h^2=l^2+w^2[/tex]

solving for  [tex]h[/tex]:

[tex]h=\sqrt{l^2+w^2}[/tex]

substituting the known values:

[tex]h=\sqrt{100^2+60^2} \\h=\sqrt{10,000+3,600}\\ h=\sqrt{13,600}\\ h=116.62yards[/tex]

the approximate distance from one corner to the opposite corner found by the Pythagorean theorem is: 116.62 yards

Answer:

c = 0

Step-by-step explanation:

A 3-variable linear system of equations is constructed after replacing known values for x and y:

[tex]16\cdot a - 4 \cdot b + c = 7[/tex]

[tex]9\cdot a + 3\cdot b + c = 0[/tex]

[tex]64\cdot a + 8\cdot b + c = 10[/tex]

After making algebraic manipulation, the following solution is found:

[tex]a = \frac{1}{4}[/tex] and [tex]b = -\frac{3}{4}[/tex] and [tex]c = 0[/tex]

The value of c is 0.

Answer:

96% confidence interval for desired retirement age of all college students is [54.30 , 55.70].

Step-by-step explanation:

We are given that a survey was conducted to determine the average age at which college seniors hope to retire in a simple random sample of 101 seniors, 55 was the  average desired retirement age, with a standard deviation of 3.4 years.

Firstly, the Pivotal quantity for 96% confidence interval for the population mean is given by;

                         P.Q. =  [tex]\frac{\bar X-\mu}{\frac{s}{\sqrt{n} } }[/tex]  ~ [tex]t_n_-_1[/tex]

where, [tex]\bar X[/tex] = sample average desired retirement age = 55 years

            [tex]\sigma[/tex] = sample standard deviation = 3.4 years

            n = sample of seniors = 101

            [tex]\mu[/tex] = true mean retirement age of all college students

Here for constructing 96% confidence interval we have used One-sample t test statistics as we don't know about population standard deviation.

So, 96% confidence interval for the population mean, [tex]\mu[/tex] is ;

P(-2.114 < [tex]t_1_0_0[/tex] < 2.114) = 0.96  {As the critical value of t at 100 degree

                                               of freedom are -2.114 & 2.114 with P = 2%}  

P(-2.114 < [tex]\frac{\bar X-\mu}{\frac{s}{\sqrt{n} } }[/tex] < 2.114) = 0.96

P( [tex]-2.114 \times {\frac{s}{\sqrt{n} } }[/tex] < [tex]{\bar X-\mu}[/tex] < [tex]2.114 \times {\frac{s}{\sqrt{n} } }[/tex] ) = 0.96

P( [tex]\bar X-2.114 \times {\frac{s}{\sqrt{n} } }[/tex] < [tex]\mu[/tex] < [tex]\bar X+2.114 \times {\frac{s}{\sqrt{n} } }[/tex] ) = 0.96

96% confidence interval for [tex]\mu[/tex] = [ [tex]\bar X-2.114 \times {\frac{s}{\sqrt{n} } }[/tex] , [tex]\bar X+2.114 \times {\frac{s}{\sqrt{n} } }[/tex] ]

                                           = [ [tex]55-2.114 \times {\frac{3.4}{\sqrt{101} } }[/tex] , [tex]55+2.114 \times {\frac{3.4}{\sqrt{101} } }[/tex] ]

                                           = [54.30 , 55.70]

Therefore, 96% confidence interval for desired retirement age of all college students is [54.30 , 55.70].
