Answer:

See below

Step-by-step explanation:

your answer for [tex]a_{1}[/tex] is correct, but I get

[tex]a_{n} = \frac{2}{25} 5^{n}[/tex] for the second answer

[tex]\frac{2}{5} 5^{n - 1} = \frac{2}{5} 5^{n} 5^{-1} = \frac{2}{5} 5^{n} \frac{1}{5}[/tex]

[tex]a_{n} = \frac{2}{25} 5^{n}[/tex]

Answer:

8.5 inches

Step-by-step explanation:

1/2 in = 5 miles

? = 85 miles.

So you would do 85/5 to figure out how many times you have to multiply 5 to get to 85.

85/5= 17

So then you would multiply 17 by 1/2 to get the answer 8.5. So that would b 8.5 inches

Answer:

The first option is

The second option is:

The equation for this option is:

Now, which option is better?

It depends on the number of x. It is assumed the genie is offering money or similar reward.

For the values of x below 50 option A is better and option B is much better for x > 50.

See the graph in the attachment, where green line represents the option A and red line is option B.

Answer:

20 years old

Step-by-step explanation:

The age of Eli would be 20 years old

A numerical expression is an algebraic information stated in the form of numbers and variables that are unknown. Information can is used to generate numerical expressions.

Consider E and F represent Eli and his Father's current ages.

We are told that E = (1/4)F.  

Eli is now one quarter of his father’s age.

But in 5 years, that will be:

(E+5) = (1/3)(F+5)      

In 5 years’ time his age will be one third of his father’s age.

We have two equations and two unknowns.  

To Find a way to eliminate one of the two variables and then solve for the remaining variable.

E = (1/4)F

(E+5) = (1/3)(F+5)

This seems to me the easiest would be to use the first equation's definition of E [=(1/4)F] in the second equation:

(E+5) = (1/3)(F+5)

((1/4)F+5) = (1/3)(F+5)

(1/4)F - (1/3)F = (1/3)*5 - 5

F - (4/3)F = (4/3)*5 - 20

-(1/3)F = (20/3) - (60/3)

-(1/3)F = (-40/3)

F = (120/3)

F = 40 years

E = 10 years  (based on E = (1/4)F)

In five years, F is 45 and E is 15, that would make Eli  1/3 of his father's age in 5 years.

Answer:

A

Step-by-step explanation:

Answer:

x = -2

y = 6

Step-by-step explanation:

Part A

If she multiplies the 1st equation by 5, then she should multiply the 2nd equation by -3.  Then add the two results

(1)      2x + 3y = 14            (2)     7x + 5y = 16

        10x + 15y = 70                 -21x - 15y = -48

        -21x - 15y = - 48

         -11x          = 22

             x = - 2                          7(-2) + 5y = 16

                                                    -14 + 5y = 16

                                                            5y = 30

                                                              y = 6

Check:  Substitute values in (1)   2(-2) + 3(6) = -4 + 18 = 14   Yea!   they work

Answer:143.60 ft

Step-by-step explanation:

Given

Height of hill [tex]h=80\ ft[/tex]

the launch velocity of the rocket is [tex]u=64\ ft/s[/tex]

At maximum height, the velocity of the rocket is zero

using the third  equation of motion [tex]v^2-u^2=2as[/tex]

[tex]\Rightarrow 0^2-64^2=2\times (-32.2)\times s\\\Rightarrow s=\dfrac{64^2}{64.4}=63.60\ ft[/tex]

The maximum height will be [tex]80+63.60=143.60\ ft[/tex]

Answer:

75

Step-by-step explanation:

Answer:

75 questions total

Step-by-step explanation:

15 questions are multiple choice and represent 20% (or 1/5) of the total questions on the test.

If 1/5 is 15, then 5/5 would be 15 x 5 = 75 questions total.

Answer:

Step-by-step explanation:

First find slope

y2 - y1 / x2 - x1

2 - 4 / 0 + 1

-2/1 = slope

Find b now

Insert any x and y

2 = -2/1 (0) + b

Solve for b

b = 2

y= -2x + 2

Answer:

y=17x-55

Step-by-step explanation:

y=ax+b

y=17x+b

-4=17(3)+b

-4=51+b

-55=b

y=17x-55
