Let the actual distance be x mile.
1/4 inch = 1/2 mile
9/2 inch = x mile
(9/2)/(1/4)=x/(1/2)
            18=2x
              x=9

the actual distance is 9 mile.

Find the solution(s) of the quadratic equation 2x2 – 3x – 35 = 0
Yuliya22 [10]

Answer: x = 5, x = -7/2

<u>Step-by-step explanation:</u>

2x² - 3x - 35 = 0

<u>Step 1:</u> Find two values whose product = 2(-35) and sum = -3:  -10 & 7

<u>Step 2: </u>Replace the b-value of -3x with  -10x + 7x:

2x² - 10x   + 7x - 35 = 0

<u>Step 3:</u> Factor the first two terms and the second two terms:

2x(x - 5)  +7(x - 5) = 0

<u>Step 4</u>: Write the factored form:

Notice that the parenthesis are identical.  This is one of the factors. The outside values are the other factor:

Parenthesis: (x - 5)

Outside: (2x + 7)

Factored form: (x - 5)(2x + 7) = 0

<u>Step 5: </u>Set each factor each to zero and solve for x:

x - 5 = 0             2x + 7 = 0

   x - 5                      x=-\dfrac{7}{2}

HELP MEE ,20 POINTS !!!!
Natali [406]

Celina says true that each of the following expressions is actually a binomial expression.

<h3>What is binomial?</h3>

The binomial is a polynomial of two-term only. For example, x + 5 where x and 5 are the two separate terms.

Celina says that each of the following expressions is actually a binomial in disguise:

a.  5abc - 2a² + 6abc = 11abc - 2a²

The is a binomial expression.

b.  5x³∙2x² - 10x⁴ + 3x⁵ + 3x∙(-2) x⁴ = 7x⁵ - 10x⁴

The is a binomial expression.

c.  (t+2)² - 4t = t² + 4

The is a binomial expression.

d.  5(a - 1) - 10(a - 1) + 100(a - 1) = 95a - 95

The is a binomial expression.

e.  (2πr - πr² )r - (2πr - πr²)∙2r = -2πr² + πr³

The is a binomial expression.

Celina says true that each of the following expressions is actually a binomial expression.

What is the rate of return on a $12,500 bond purchased at $10,750 with a 15% coupon?
Firdavs [7]
With the 15% coupon, you will get $1,875. (Because 15% of the bond's price $12,500 is $1,875.) Solution: 0.15 x 12500 = 1875

So $1,875 is to be divided by the actual price of the bond which is $10,750. (1, 875 ÷<span>  10,750 = 0.1744 convert this to percent to get the rate of return)
 0.1744 = 17.44 %

The rate of return is 17.44%.</span>
