If a^b=x, what is a^(b+2)?

1 answer:

3 0

$\bf \boxed{a^b=x}\implies \sqrt[b]{a^b}=\sqrt[b]{x}\implies \boxed{a=\sqrt[b]{x}}\\\\
-------------------------------\\\\
a^{b+2}\implies a^b\cdot a^2\implies \boxed{x}\cdot \left( \boxed{\sqrt[b]{x}} \right)^2\implies x\cdot \sqrt[b]{x^2}\implies x\sqrt[b]{x^2}$

Answer:

reflection, then translation
rotation, then translation

Step-by-step explanation:

When the points designating each triangle are considered in order, they are seen to be in clockwise order. Segment FG is oriented to the west, while corresponding segment VW is oriented to the east. This means the figure could have been rotated 180° or reflected across a point. Either way, some translation may be necessary to align the figures as shown.

Possible transformations include ...

reflection across a point, then translation (depending on the location of the point)
rotation 180° about a point, then translation (depending on the location of the point)

___

If one of the triangles is reflected across the midpoint of GW, it will coincide with the other triangle. Hence only one reflection across a chosen point is required. Of course, reflection across a point is identical to rotation 180° about that point. For any other point of reflection or rotation, translation will be involved.

If Ms. P wants to withdraw $900 from an account earning 4% average annual interest rate at the start of each year for 7 years, h

Ksju [112]

Answer:

Amount he must have in his account today is $5,617.92

Step-by-step explanation:

Data provided in the question:

Regular withdraw amount = $900

Average annual interest rate, i = 4% = 0.04

Time, n = 7 years

Now,

Present Value = $C \times\left[ \frac{1-(1+i)^{-n}}{i} \right] \times(1 + i)$

here,

C = Regular withdraw amount

Thus,

Present Value = $C \times\left[ \frac{1-(1+i)^{-n}}{i} \right] \times(1 + i)$

Present Value = $900 \times\left[ \frac{1-(1+0.04)^{-7}}{ 0.04 } \right] \times(1 + 0.04)$

Present Value = $936 \times\left[ \frac{1 - 1.04^{-7}}{ 0.04} \right]$

Present Value = $936 \times\left[ \frac{1 - 0.759918}{ 0.04} \right]$

Present Value = 936 × 6.00205

Present Value = $5,617.92

Hence,

Amount he must have in his account today is $5,617.92

Answer:

See Explanation

Step-by-step explanation:

The question is not properly formatted.

<em>Assume that the given parameter is: 4</em>

Required

The multiplicative inverse

Let a number be x, and the multiplicative inverse be y. The relationship between them is:

$y * x = 1$

Make y the subject

$y = \frac{1}{x}$

So;; for the assumed given parameter.

The multiplicative inverse is:

$y = \frac{1}{4}$
