Answer:

2√5

Step-by-step explanation:

Were there answer choices from which to choose?  If so, please share them next time.

The Pythagorean Theorem would suit very well in finding this distance.

The horizontal distance between the two points is 2 (I'm neglecting the - sign), and the vertical distance is 4.  Thus, the distance between the two points is

d = √ [ 2^2 + 4^2 ] = √ [20]  = √4*√5  = 2√5

A2 = -8 and a5 = -512<br> Find a10
yawa3891 [41]

Answer:

The value of a₁₀ is -1352

Step-by-step explanation:

a₂ = -8

a₅ = -512

Now,

a₂ = -8 can be written as

a + d = -8 ...(1) and

a₅ = -512 can be written as

a + 4d = -512 ...(2)

Now, from equation (2) we get,

a + 4d = - 512

a + d + 3d = - 512

(-8) + 3d = - 512 (.°. <u>a + d = </u><u>-8</u><u>)</u>

3d = - 512 + 8

3d = - 504

d = - 504 ÷ 3

d = - 168

Now, for the value of a put the value of d = -168 in equation (1)

a + d = -8

a + (-168) = -8

a - 168 = -8

a = 168 - 8

a = 160

Now, For a₁₀

a₁₀ = a + 9d

a₁₀ = 160 + 9(-168)

a₁₀ = 160 - 1512

a₁₀ = -1352

Thus, The value of a₁₀ is -1352

1. The county fair charges $1.50 per ticket for the rides. Jermaine bought 20 tickets for the rides and spent a
makvit [3.9K]

Cost per ticket for the rides = $1.50.

a) Let us assume the number of ride tickets = x.

Total cost of x number of rides = y.

Total amount spent = $48.75.

Amount spent on 20 tickets = 20 × 1.50 = $30

<em>Fair admission charge = Total amount spent - Amount spent on 20 tickets</em>

<em> =  $48.75 - $30 = $18.75.</em>

Let us apply slope-intercept form y=mx+b to get the equation.

Total cost of x number of tickets at the rate $1.50 each ticket = 1.50x.

To<em>tal cost of fair = Total cost of x number of tickets + Fair admission charge.</em>

<h3>b) y = 1.50x + 18.75.</h3>
