S is inversely proportional to t<br> When s = 0.5, t = 7<br> Work out s when t = 0.8
defon

Given:

s is inversely proportional to t.

When s = 0.5, t = 7.

To find:

The value of s when t=0.8.

Solution:

s is inversely proportional to t.

s\propto \dfrac{1}{t}

s=\dfrac{k}{t}       ...(i)

Where, k is the constant of proportionality.

Putting s=0.5 and t=7, we get

0.5=\dfrac{k}{7}

0.5\times 7=k

3.5=k

Putting k=3.5 in (i), we get

s=\dfrac{3.5}{t}

This is the equation of proportionality.

Putting t=0.8, we get

s=\dfrac{3.5}{0.8}

s=4.375&#10;

Therefore, the value of s is 4.375 when t=0.8.

What is the measure of angle A?
antoniya [11.8K]

Answer:

A = 19.47

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

sin theta = opp / hypotenuse

sin A = 2/6

Take the inverse sin of each side

sin ^-1 ( sin A) = sin ^-1 (2/6)

A =19.47122063

To the nearest hundredth

A = 19.47

2. A bank representative studies compound interest, so she can better serve
Kaylis [27]

Answer:

Step-by-step explanation:

Given that a  bank representative studies compound interest, so she can better serve  customers. She analyzes what happens when $2,000 earns interest several  different ways at a rate of 2% for 3 years.

a) the interest if it is computed using simple interest. 12.00

=\frac{2000(3)(12)}{100} \\=720 dollars

b) the interest if it is compounded annually.

=2000(1.12)^3-2000\\= 809.86 dollars

c) the interest if it is compounded semiannually

=2000(1.06)^6 -2000\\= 837.04

d) the interest if it is compounded quarterly.

=2000(1.03)^12 -2000\\= 851.52

e) the interest if it is compounded monthly.

=2000(1.01)^24 -2000\\= 861.54
