Answer:

$38,562.5

Step-by-step explanation

Using the compound interest formula

A = P(1+r/n)^nt

P is the principal = $125,000

r is the rate = 6% = 0.06

time t  = 5years

n = 0.25 (quarterly payment)

Substitute

A = 125000(1+0.06/0.25)^5(0.25)

A = 125000(1+ 0.24)^1.25

A = 125000(1.24)^1.25

A = 125000(1.3085)

A = 163,562.5

Hence the interest earned = 163,562.5 - 125000

interest earned = $38,562.5

What’s the distance between (4,-9) and (5,3)
laila [671]

Answer: Distance = √145

Concept:

Here, we need to know the concept of the distance formula.    

The distance formula is the formula, which is used to find the distance between any two points.

If you are still confused, please refer to the attachment below for a clear version of the formula.

Solve:

<u>Given information</u>

(x₁, y₁) = (4, -9)

(x₂, y₂) = (5, 3)

<u>Given formula</u>

Distance = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

<u>Substitute values into the formula</u>

Distance = \sqrt{(5-4)^2+(3+9)^2}

<u>Simplify values in the parentheses</u>

Distance = \sqrt{(1)^2+(12)^2}

<u>Simplify exponents</u>

Distance = \sqrt{1+144}

<u>Simplify by addition</u>

Distance = \sqrt{145}

Hope this helps!! :)

Which is an example x-intercept of the graph of the function y=tan(x-(5pi/6))
emmainna [20.7K]
Answer: x = 5π/6

Explanation:

1) Given function:

y=tan(x- \frac{5 \pi }{6} )

2) x-intercept are the roots of the function, i.e. the solution to y = 0

3) to find when y = 0, you can either solve the equation or look at the graph.

4) Solving the equation you get:

y = 0 ⇒ tan(x - 5π/6) = 0 ⇒ x - 5π/6 = arctan(0)

arctan(0) is the angle whose tangent is zero,so this is 0

⇒ x - 5π/6 = 0 ⇒ x = 5π/6.

Then, one example of an x-intercept is x = 5π/6, which means that when x = 5π/6, the value of the function is 0.

Since, the tangent function is a periodic function, there are infinite x-intecepts, that is why the questions asks for one example and not all the values.

You can verify by replacing the value x = 5π/6 in the given function:

y = tan (5π/6 - 5π/6) = tan(0) = 0.
