Answer: The answer is greater than (>).

Step-by-step explanation: We are to find the relationship between AD and EC in the given figure.

In ΔABD and ΔBEC, we have

∠DBA = 30°, ∠EBC = 25°,

AB = BC = 10 units,

BE = BD = 8 units.

Since ∠DBA > ∠EBC, so the sides opposite to them will also follow the same pattern.

That is

side opposite to ∠DBA > the side opposite to ∠EBC.

So, AD > EC.

Thus, the required sign is greater then (>).

Convert the following repeating decimal to a fraction in simplest form .31 with the 1 repeating

bekas [8.4K]

Answer:

14/45

Step-by-step explanation:

So we have the fraction:

$0.3\bar1=0.31111...$

We can do this algebraically. Follow to following steps:

Let's let this number equal to n. Thus:

$0.31111...=n$

Since there is only 1 digit repeating, let's multiply everything by 10. So:

$3.1111...=10n$

Now, subtract n from both sides:

$3.1111-n=10n-n$

On the left, substitute the number for n. On the right, combine like terms:

$3.1111...-0.31111...=9n$

All of the 1s will cancel. So:

$3.1-0.3=9n$

Subtract:

$2.8=9n$

Divide both sides by 9:

$n=2.8/9$

Remove the decimal by multiplying both sides by 10:

$n=28/90$

Reduce:

$n=14/45$

And we're done!

Use a calculator to check:

$14/45\stackrel{\checkmark}{=}0.31111...$

Which of the following is an X-intercept of the function f(X)=X^3-5X^2-8X+48

Anton [14]

You have to searh the x values that make f(x) = 0

Factoring this equation is very difficult.

You can divide by x+3 and you will find that the equation can be factored as

(x+3)(x-4)^2

That means that x = -3 and x = 4 make f(x) = 0

Then the points are (-3,0) and (4,0).
