Answer:

177 and 178

Step-by-step explanation:

First, the expression for the 2nd mile marker is x+1.

Now, you add x and x + 1 together to get 2x + 1

Next, make 2x + 1 equal to 355

Now subtract 1 and then divide by two on both sides to get x = 177.

This means that the first mile marker is 177 and the next is 178.

Suppose we want to choose 5 objects, without replacement, from 15 distinct objects.
goblinko [34]

15444 ways we can choose 5 objects, without replacement, from 15 distinct objects.

Given that, suppose we want to choose 5 objects, without replacement, from 15 distinct objects.

<h3>What is a permutation?</h3>

A permutation is a mathematical calculation of the number of ways a particular set can be arranged, where the order of the arrangement matters.

Now, 13P_{5}= 13!/(13-5)!

= 13!/8! = 13x12x11x10x9= 1287 x 120 = 15,444

Therefore, 15444 ways we can choose 5 objects, without replacement, from 15 distinct objects.

Find the interest generated if one invests $6000 for 9 years at 7% per annum with interest compounded monthly
marysya [2.9K]

Answer:

principle= 6000

time =9 years

rate = 7%

so,

compound interest = p((1+r/100)^t. -1)

= 6000((1+0.07)^9 -1)

=6000(1.84-1)

=6000*0.84

=5040

Solve the equation using the quadratic formula
amm1812

Answer:

Step-by-step explanation:

Rewrite this quadratic equation in standard form:  2n^2 + 3n + 54 = 0.  Identify the coefficients of the n terms:  they are 2, 3, 54.

Find the discriminant b^2 - 4ac:  It is 3^2 - 4(2)(54), or -423.  The negative sign tells us that this quadratic has two unequal, complex roots, which are:

     -(3) ± i√423        -3 ± i√423

n = ------------------- = ------------------

             2(2)                      4
