Answer:

[tex]\frac{1}{64}[/tex]

Step-by-step explanation:

Using the rule of exponents

[tex]a^{-m}[/tex] = [tex]\frac{1}{a^{m} }[/tex]

and 4³ = 4 × 4 × 4 = 16 × 4 = 64

Then

[tex]4^{-3}[/tex] = [tex]\frac{1}{4^{3} }[/tex] = [tex]\frac{1}{64}[/tex]

Answer:

A: *Graph shown in image*

B: She will reach her goal when the x is 14 (14,460) with y being 460 (or the goal) giving you the equation [tex]y = \frac{50}{2} x + 110[/tex] going up 50 and going right 2 with x being 7 meaning you would have to go up 50 and right 2, seven times to reach 460.

Step-by-step explanation:

A: From your previous question you asked 14 hours ago with a screenshot, you did your graph wrong so for YOU make your graph look like the second image. (Plot the point 0,110 for the y intercept and plot -4.4,0 for the x line)

B: Lot's of explaining but you will get it once you add it to your own graph and go with the flow. Kind of like slope intercept form.

For C: you can answer in your own words since I gave you the priority answer(s)

Solving the quadratic equation, it is found that the number of teams is greater than 1000 after 3.1 years.

The number of teams after x years is given by:

[tex]T(x) = 17.155x^2 + 193.68x + 235.81[/tex]

Initially, there are T(0) = 236 teams. If will 1000 be when T(x) = 1000, thus:

[tex]17.155x^2 + 193.68x + 235.81 = 1000[/tex]

[tex]17.155x^2 + 193.68x - 764.19 = 0[/tex]

Which has coefficients [tex]a = 17.155, b = 193.68, c = -764.19[/tex], then:

[tex]\Delta = (193.68)^2 - 4(17.155)(-764.19) = 89950.66[/tex]

[tex]x_{1} = \frac{-193.68 + \sqrt{89950.66}}{2(17.155)} = 3.1[/tex]

[tex]x_{2} = \frac{-193.68 - \sqrt{89950.66}}{2(17.155)} = -14.3[/tex]  

We want the positive root, so the number of teams is greater than 1000 after 3.1 years.

Comparing the equivalent cost of Milk in Euro in the two countries, then we can conclude that Milk is a better value for money in Paris.

In other to make accurate comparison of the cost ; we need to using the same unit or milk and same currency value :

Cost of 1 pint of Milk in London :

1 pint = 0.58 pounds

The equivalent value of 1 pint of Milk in terms of Euro in London will be :

1 pound = 1.17 euro

0.58 pound = x

Cross multiply :

x = 1.17 × 0.58

x = 0.6786 euro

x = 0.68 euro

Hence, 1 pint of Milk cost 0.68 euro in London

Cost of 1 pint of Milk in Paris :

1 Litre = 1.76 pint

Hence,

1.76 pint = 1.05 euro

1 pint = c

1.76c = 1.05

c = 1.05 / 1.76

c = 0.597 euro

Hence, cost of 1 pint of Milk cost 0.60 euro in Paris

Therefore, since the cost of Milk in Paris cost less in Paris than in London, then Milk is a better value for money in Paris.

Think of it this way what if an exponent had 1 so like 10^1

that still equals 10, and does not change anything, so you need to add one more to the exponent as the first number does not change how many types the number is multiplied. Hope this helps

Answer:

square has 4 sides.

perimeter adds all sides to make 72

72/4=18 units each side

length * width =area of square

square has all sides equal, so 3y and 2x are tricks to confuse. All sides are 18.

The value of the algebraic expression when n is given as 6 will be 38.

An algebraic expression is when we use numbers and words in solving a particular mathematical question.

Based on the information given in the question, the expression will be:

= 1 + 7n - 5

Note that the value of n = 6

Therefore, 1 + 7n - 5 will be:

= 1 + 7n - 5

= 1 + 7(6) - 5

= 1 + 42 - 5

= 38

Step-by-step explanation:Therefore, the value of the algebraic expression when n is given as 6 is 38.
