Answer:

m=12

Explanation:

Given any quadratic function, y=ax²+bx+c.

We can determine the nature of the roots of such quadratic function by examining the discriminant, D where:

$D=b^2-4ac$

• If D>0, the roots are real and unequal.

,

• If D=0, the roots are real and equal.

,

• If D<0, the roots are complex.

In our given equation:

$\begin{gathered} y=18x^2+mx+2 \\ a=18,b=m,c=2 \end{gathered}$

For the function to have exactly one zero, the value of D=0.

$\begin{gathered} D=b^2-4ac=m^2-4(18)(2)=m^2-144 \\ D=0\implies m^2-144=0 \\ Add\text{ 144 to both sides.} \\ m^2=144 \\ Take\text{ the square root of both sides} \\ \sqrt{m^2}=\sqrt{144} \\ m=12 \end{gathered}$

The value of m for which the function will have one zero is 12.

Rashid has been purchasing bonds from a company that has recently gotten poor ratings for its ability to pay Its vendors. As a r

svet-max [94.6K]

Answer:

The answer is letter D, credit risk.

Step-by-step explanation:

A bond is considered to be a contract between two occurring parties. It allows companies to borrow money from people (investors). These investors purchase the bond and are given a certain interest for a particular period of time. The rate varies according to the economic situation or the company's standing. This affects the supply and demand for the bond.

Remember that the price of the bond and the interest rate are indirectly proportional. This means that as the price of the bond increases, the interest rate decreases and vice-versa.

In the situation above, Rashid is facing a credit risk as an investor. He has been purchasing bonds from a company that has recently gotten a poor rating. This means that the company is not performing well. This can affect the amount of money (including the interest) that will be paid back to Rashid. There is a chance that some of the amount of money he invested will not be returned to him. It was also mentioned that the bond's interest rate has increased. This means that the bond prices will decrease and thus the number of bond investors will also decrease. The issuer of the bond in this situation can have a hard time paying the investor back.

Admission to the fair is $15 each ride cost $3 micah spent a total of $36 he spent all of his money on rides and admission

WINSTONCH [101]

Answer:

7

Step-by-step explanation:

Admission cost = $15

Cost per ride = $3

Total amount spent = $36

We can obtain the number of rides thus :

Let number of rides = x

Admission cost + (cost per ride * number of rides) = total amount spent

15 + 3x = 36

3x = 36 - 15

3x = 21

x = 21 / 3

x = 7

Number of rides = 7
