The correct answer is A
B is wrong because IAJ is not an angle because it doesn’t have a line that connects I and A
C is wrong because the segments are not in according order it would be correct if it said IJ = KJ
D is wrong because it says that Point a is the midpoint however J is the midpoint for both intersecting lines.

Answer:

Step-by-step explanation:

If a line bisects a segment, both sides of the segment are equal. Therefore, IJ and JK have the same length, and are equal.

Solve for x.

xenn [34]

Answer:

$a \: \: x = \frac{ -1 ± i\sqrt{139}}{14}$

Explanation:

Since this is unfactorable, use the Quadratic Formula:

$x = -b ± \frac{ \sqrt{ {b}^{2} - 4ac}}{2a}$

Now, take the information and input it:

$-1 ± \frac{ \sqrt{1 - 4(7)(5)}}{2(7)} \\ \\ -1 ± \frac{ \sqrt{ -139}}{ 14} = \frac{-1 ± i\sqrt{139}}{14}$

Each investment matures in 3 years. The interest compounds annually.

bearing in mind that 4¾ is simply 4.75.

$\bf ~~~~~~ \textit{Compound Interest Earned Amount} \\\\ A=P\left(1+\frac{r}{n}\right)^{nt} \quad \begin{cases} A=\textit{accumulated amount}\\ P=\textit{original amount deposited}\dotfill &\$750\\ r=rate\to 4.75\%\to \frac{4.75}{100}\dotfill &0.0475\\ n= \begin{array}{llll} \textit{times it compounds per year}\\ \textit{annually, thus once} \end{array}\dotfill &1\\ t=years\dotfill &3 \end{cases} \\\\\\ A=750\left(1+\frac{0.0475}{1}\right)^{1\cdot 3}\implies A=750(1.0475)^3\implies A\approx 862.032$

well, the interest for each is simply A - P

695.575 - 600 = 95.575.

862.032 - 750 = 112.032.

That’s the number is written in standard scientific notation?

Nata [24]

Option D: 3.47*10^-7 is the correct answer

Step-by-step explanation:

In order to determine the number written in standard scientific notation, first of all we have to understand how the scientific numbers are written

the scientific numbers are written in the form of:

$a*10^n$

Here

a is a number between 1 and 10 while the value of n can be only integer (positive or negative)

so,

In the given options:

Option A has a number larger than 10 in place of a so it is not in standard notation

Option B has a number less than 1 in place of a so it is also not in standard notation

Option C has a number larger than 10 in place of a so it is not in standard notation

Option D is in standard scientific notation as 1<3.47<10 and the power of 10 is integer

Hence,

Option D: 3.47*10^-7 is the correct answer
