Anastasy [175]

a) By Pythagoras theorem , h^2 is = a^2 + b^2 where a is the hypotenuse and a and b are the legs.

=) 15^2 = x^2 + y^2

That is the relation

b) area of triangle = 1/2 x height x base

=) 1/2 * x * y = 30

=) xy = 15cm

An inheritance of $40,000 is divided among three investments yielding $3,500 in interest per year. The interest rates for the th

a_sh-v [17]

Answer:

x = $ 16,000 , y = $13,000 z= $11,000

Step-by-step explanation:

given,

Investment amount $40,000

three investments yielding = $3,500

three investments are 7%, 9%, and 11%

second and third are $3,000 and $5,000 less than the first

0.07 x + 0.09 y + 0.11 z = $ 3,500

x + (x - 3000 ) + (x - 5000) = $ 40,000

3x = $48,000

x = $ 16,000

y = 16000 - 3000 = $ 13,000

z = 16000 - 5000 = $ 11,000

the investment by each

x = $ 16,000 , y = $13,000 z= $11,000

The population of a town is 12,000, and it grows at a rate of 5% per year. Write an exponential function in the form <img src="h

Ksivusya [100]

Answer: Exponential function: $y=12000(1.05)^x$

Step-by-step explanation:

Exponential function: $y=ab^x$ , a = initial value , x= time, b= growth factor , b= 1+r , where r=rate of growth.

Given: Initial population = a= 12,000,

rate of growth = r= 5% = 0.05

Then, b= 1+r= 1+ 0.05 = 1.05

Substitute value of a and b in (i), we get

$y=12000(1.05)^x$

Hence, The required exponential function: $y=12000(1.05)^x$ , where x= time.
