Step-by-step explanation:

$\because 3^2 + 4^2 = 9 +16 = 25...(1)\\\&\: 5^2 = 25.... (2)$

From equations (1) & (2), it is obvious that:

$\because 3^2 + 4^2 =5^2$

Hence, by converse of Pythagoras theorem: 3, 4 5 forms right triangle.

$\therefore m\angle A = 90\degree \\or\: \angle A \: is \: a\: right\: angle$

\therefore \tan \theta = \frac{4}{3}[/tex]

£2000 is invested with an interest rate of 2% per year. How much is the investment worth after 3 years

Stells [14]

Answer:

£2122.42

Step-by-step explanation:

To find the answer, use the compound interest formula:

A = P ( 1 + (r/n) ) ^ (n*t)

A = 2,000 ( 1 + (0.02/1) ) ^ (1*3)

A = 2,000 ( 1 + 0.02 ) ^ 3

A = 2,000 ( 1.02 ) ^ 3

A = 2,000 ( 1.061208 )

A = about 2122.2 pounds

Okay THIS is right. I'm so sorry.

If f (2) is an exponential function where f(-2.5) = 9 and f(7) = 91, then find

mafiozo [28]

Answer:

$f(12) = 323.02$

$f(12) = 16.7 * 1.28^{12$

Step-by-step explanation:

Given

$f(-2.5) = 9$

$f(7) = 91$

$f(12) = 16.7 * 1.28^{12$

Required

$f(12)$

An exponential function is:

$f(x) = ab^x$

$f(-2.5) = 9$ implies that:

$9 = ab^{-2.5}$

$f(7) = 91$ implies that:

$91 = ab^7$

Divide both equations

$91/9 = ab^7/ab^{-2.5}$

$91/9 = b^7/b^{-2.5}$

Apply law of indices

$91/9 = b^{7+2.5}$

$10.11 = b^{9.5}$

Take 9,5th root of both sides

$b = 1.28$

So, we have:

$9 = ab^{-2.5}$

$9 = a * 1.28^{-2.5}$

$9 = a * 0.54$

$a = 9/0.54$

$a = 16.7$

f(12) is calculated as:

$f(x) = ab^x$

$f(12) = 16.7 * 1.28^{12$

$f(12) = 323.02$
