Answer:

a = 5

Step-by-step explanation:

If it's easier for you, you can replace n(a) with y and put a as x.

Now the equation is y = 7x + 4.

It asks you to put in 39 as y.

39 = 7x + 4.

To solve this, the goal is to isolate the variable on one side. The first step I see is to subtract the 4 from both sides.

35 = 7x

Now divide both sides by 7 and we're done!

Using angle bisector theroem, we have:

$\frac{8}{5}=\frac{6}{x}$

Solving for x, we get x= $\frac{15}{4}$ or x=3.75

Write a quadratic function in standard form whose graph passes through (4,0) and (6,0)

Diano4ka-milaya [45]

Answer:

f(x) = x² - 10x + 24

Step-by-step explanation:

The quadratic function has a graph that passes through the points (4,0) and (6,0).

Therefore, the graph has two x-intercepts at x = 4 and x = 6 and those are the roots of the equation.

So, (x - 4) and (x - 6) are two factors of the quadratic equation.

Then we can write the equation as

f(x) = (x - 4)(x - 6)

⇒ f(x) = x² - 4x - 6x + 24

⇒ f(x) = x² - 10x + 24

Hence, this is the required quadratic function in standard form. (Answer)

What is the monthly finance charge if the average daily balance is $15, the daily periodic rate is 0.06%, and the number of days

MariettaO [177]

Given

The average daily balance is $15

The daily periodic rate = 0.06%

The number of days in the cycle is 30

Find out the monthly finance charge.

To proof

Let us assume that the monthly finance charge = x

As given in the question

The average daily balance = $15

daily periodic rate = 0.06%,

First convert 0.06% in decimal form

$=\frac{0.06}{100}$

= 0.0006

Daily finance charge = 0.0006 × 15

= 0.009

number of days in the cycle is 30

now

monthly finance charge

Than the equation becomes

x = 15 × 0.0006 × 30

x = 0.009× 30

x = $0.27

Thus the monthly finance charge is $0.27

Hence proved
