Answer:

all real numbers

Step-by-step explanation:

Answer:

The domain of this function is all real numbers

Step-by-step explanation:

Unless there is a domain restriction for the function, the domain of a function is all real numbers. This means that all we need to do is determine whether there is a domain restriction.

The things that cause a domain restriction are: an x in the denominator of a fraction like [tex]f(x)=\frac{1}{x}[/tex] or a radical like [tex]f(x)=\sqrt{1-x}[/tex]

As there are no variables in the denominator or a radical, we can conclude that the domain of this function is all real numbers.

Answer:

[tex] p(s) = -24s^2 +2200 s -18000[/tex]

If we use the valie of s =60 we have

[tex] p(60) = -24 (60)^2 +2200*60 -18000[/tex]

And after solve we got:

[tex] p(60)= -86400 +132000 -18000 =27600[/tex]

So then the best option for this case would be:

$27,600

Step-by-step explanation:

Using the following info in order to complete the problem:

p(s)=-24s^(2)+2200s-18000

$112,560

$27,600

$111,120

$236,400

$14,240

We have the following function given:

[tex] p(s) = -24s^2 +2200 s -18000[/tex]

If we use the valie of s =60 we have

[tex] p(60) = -24 (60)^2 +2200*60 -18000[/tex]

And after solve we got:

[tex] p(60)= -86400 +132000 -18000 =27600[/tex]

So then the best option for this case would be:

Answer: B

21x^2-17x+2

Step-by-step explanation:

Answer: x-intercept = 2, y-intercept = -6

Step-by-step explanation:

To solve this problem, we must first convert 6x - 2y = 12 to slope-intercept form by getting y by itself.

1. 6x - 2y = 12

2. -2y = 12 - 6x

3. -2y/-2 = 12/-2 - 6x/-2

y = 3x - 6

Using our knowledge of what the slope-formula represents, we know that the -6 is the y-intercept.

To find the x-intercept, we set the formula equal to 0 instead of y and solve for x.

1. 0 = 3x - 6

2. 0 + 6 = 3x

3. 6/3 = 3x/3

x = 2

Answer:

Area of the garden in standard form:

Area = (2t^2) + 7t - 4

The dimension of the garden is 8ft × 7ft

Step-by-step explanation:

Length of the rectangular garden, L = t+4

Width of the garden, B = 2t - 1

Area = length * width

Area = (t+4) * ( 2t-1)

Area = (2t^2) + 7t - 4..….......(1)

If the Area = 56 ft^2

Substitute Area into (1)

56 = (2t^2) + 7t - 4

(2t^2) + 7t - 60 = 0

(2t^2) - 8t + 15t - 60 = 0

2t(t - 4) + 15(t - 4) = 0

(2t+15) (t-4) = 0

Let 2t + 15 =0

t = -7.5

Let t - 4 = 0

t = 4

* When t = -7.5

Length, L = -7.5 + 4 = -3.5 ft

Width, B = 2(-7.5) -1 = -16 ft

Since length and breadth cannot be negative, t = -7.5 is not possible

** When t = 4

Length, L = 4+4 = 8 ft

Width, B = 2(4) - 1 = 7 ft

Therefore, the dimension of the garden is 8ft × 7ft

Answer:

The dimension is 8ft by 7ft

Step-by-step explanation:

Given data

Length l =  [tex](t+4)[/tex]

Width w=  [tex](2t-1)[/tex]

the area  is expressed as  [tex]A= length * width[/tex]

[tex]A= (t+4)*(2t-1)\\A= t(2t-1) +4(2t-1)\\A= 2t^{2}-t+8t-4\\[/tex]

collecting like terms we have

[tex]A= 2t^{2} +7t-4[/tex]

hence our expression for area is [tex]A= 2t^{2} +7t-4[/tex]

given that the area is [tex]56ft^{2}[/tex]  to solve for the sides we need to first solve fot t

equating the expression for area to 56 we can solve for t

[tex]A= 2t^{2} +7t-4= 56[/tex]

taking the constant term to the other side and solve we have

[tex]A= 2t^{2} +7t-4-56\\A= 2t^{2} +7t-60\\[/tex]

we can substitute two factors for 7t that when multiplied we give -60 and when added we give 7  these factors are 15 and -8

[tex]A= 2t^{2} +7t-60\\\\A= 2t^{2} -8t+15t-60\\2t^{2} -8t+15t-60=0\\\\2t(t-4) +15(t-4)= 0\\2t+15=0, (t-4)= 0\\2t=-15, t= -7.5\\t= 4[/tex]

t=4  hence the length is

[tex](t+4)\\(4+4)= 8ft\\[/tex]

hence the width  is

[tex](2t-1)\\(2*4-1)= (8-1)= 7ft[/tex]

Answer:

Total amount to be paid = $655

Step-by-step explanation:

Given,

Total price before coupon is  = 261.36 +381.25+77.52

= $720.13

Discount = 15%

Amount of discount = 15% of total amount

Amount of discount = [tex]\frac{15}{100} \times 720.13[/tex]

= $108.02

Remaining amount = Total amount - discount amount

Remaining amount = $720.13 - $108.02

= $612.11

Sales tax = 6%

Amount of sales tax = 6% of remaining amount

[tex]=\frac{6}{100} \times 612.11\\\\=42.85[/tex]

Amount to be paid = Remaining amount + sales tax

= 612.11 + 42.85

= 654.96

Rounding off to nearest whole number;

Total amount to be paid = $655

Answer:

The area would be 1 : 16 ratio, of the smaller rectangle to the larger one.

Step-by-step explanation:

I used a rectangle with the side length of 1 to model this for me. You can choose any number, but 1 is easy to multiply.

If the original rectangle had a side length of 1 and 1, the area would be 1.

If you reduce the size to 1/4th of the size, the area would be 0.0625, or 1/16th of the original.

[tex]x = 6(7 + 2y)[/tex]

Answer:

Given

x/7 + 2y = 6

Multiply through by 7 to clear the fraction

x + 14y = 42 ( subtract 14y from both sides )

x = 42 - 14y

Answer:

15/18=5/6

14/18=7/9

the last symbol

Step-by-step explanation:

Answer:

For the first part (the part on the top), you have to make the fractions have the same denominator. To do this, you must find the LCM (least common multiple) of 6 and 9. The LCM of 6 and 9 would be 18 because 6x3=18 and 9x2=18. Now, both of the denominators are 18. But we still have to change the numerators! To change the numerators, we must multiply them by the same numbers that we multiplied the denominators by. So for 5/6, we would multiply the 5 (the numerator) by 3 because that is what we multiplied the 6 by. 5x3=15. So now the first fraction, 5/6, is 15/18 (that's the answer). For 7/9, we still have to multiply the 7 (the numerator) by 2. 7x2=14. So now this fraction, 7/9, is 14/18 (that's the answer).

So basically what I was saying is that 5/6=15/18 and 7/9=14/18.

For the second part (the part on the bottom), you have to compare the fractions. It is difficult right now as it is written as 5/6 and 7/9. But remember what we did for the first part! Think about these fractions as 15/18 and 14/18. 15/18 is larger than 14/18. So the answer for the part on the bottom is 5/6 > 7/9.

Hope this helps! :)
