Answer:

$h(x) = 57(0.8)^x$

Step-by-step explanation:

Given

$f(x) = 32(0.8)^x$

$g(x) = 25(0.8)^x$

Required

A function that represents the total resale value of the two vehicles

To do this, we simply add up the functions

$h(x) = f(x) + g(x)$

$h(x) = 32(0.8)^x + 25(0.8)^x$

Factorize

$h(x) = (32 + 25)(0.8)^x$

$h(x) = 57(0.8)^x$

alukav5142 [94]

Answer:

x = 4

Step-by-step explanation:

$\frac{12}{16} =\frac{5x-2}{6x}$

$6x(\frac{12}{16} )=5x-2$

$\frac{72x}{16} =5x-2$

$72x = 16(5x-2)$

$72x=80x-32$

$8x=32$

$x=32/8=4$

Hope this helps

work out the circumfrance of this cirlce take pi to be 3.142 and write down all the digits given by your calculator raduis 10cm

Simora [160]

Answer:

$C=68.4$

Step-by-step explanation:

$Circumference=2\pi r$

Pi = 3.142

r (radius) = 10 cm

$C=2(3.142)(10)$

$C=(6.84)(10)$

$C=68.4$

Therefore, circumference of a circle with 10 cm radius is <u>68.4.</u>
