Assuming you're concerned with interest rate problems, r is generally involved in something like the formula ...

... i = prt

So, r will have the units of ...

... r = i/(pt) = (dollars)/(dollars·year) = 1/year

That is, r is <em>(some fraction) per year</em>.

_____

Often, the fraction is expressed as a percentage. The fraction will be unitless (as percentages are), leaving the units of r as year⁻¹.

Determine two pairs of polar coordinates for (3,-3) when 0
Xelga [282]

The two pairs of polar coordinates for the given point (3, -3) with 0° ≤ θ < 360° are (3√2, 135°) and (3√2, 315°).

<h3>What is a polar coordinate?</h3>

A polar coordinate is a two-dimensional coordinate system, wherein each point on a plane is typically determined by a distance (r) from the pole (origin) and an angle (θ) from a reference direction (polar axis).

Next, we would determine the distance (r) and angle (θ) as follows:

r = √(3² + (-3)²)

r = √(9 + 9)

r = 3√2.

θ = tan⁻¹(-3/3)

θ = tan⁻¹(-1)

θ = 3π and 7π/4 (second and fourth quadrants).

Converting to degrees, we have:

θ = 135° and 315°.

Please can you give me the answers to the questions above in standard form.​
ivanzaharov [21]

Answer:

a) 4.5 \times 10^{11}

b) 3.5 \times 10^{3}

Step-by-step explanation:

a) We have to simplify the below expression in standard form.

The expression is (5\times 10^{3}) \times (9 \times 10^{7})

Now, (5\times 10^{3}) \times (9 \times 10^{7})

= (9 \times 5) \times (10^{3} \times 10^{7})

= 45 \times 10^{(3 + 7)} {Since a^{b} \times a^{c} = a^{(b + c)}}

= 45 \times 10^{10}

= 4.5 \times 10^{11} (Answer)

b)  We have to simplify the below expression in standard form.

The expression is (7\times 10^{5}) \div (2 \times 10^{2})

Now, (7\times 10^{5}) \div (2 \times 10^{2})

= (7 \div 2) \times (10^{5} \div 10^{2})

= 3.5 \times 10^{(5 - 2)} {Since a^{b}\div a^{c} = a^{(b - c)}}

= 3.5 \times 10^{3} (Answer)
