((-8 2/5)/(-4 1/10))*(-1/2)
(-(8*5+2)/5)/(-(4*10+1)/10)*(-1/2)
(-(42/5))/(-(41/10))*(-1/2)
((42/5)/(41/10))*(-1/2)
((42/5)*(10/41))*(-1/2)
((42*10)/(5*41))*(-1/2)
((420)/(205))*(-1/2)
(84/41)*(-1/2)
-((84*1)/(41*2))
-((84)/(82))
=-(42/41)
=-42/41
=-1 1/41

Which of the following investments could be represented by the function A = 250(1 + 0.08/12)12 × 4?
Alekssandra [29.7K]

hello,

the first term is 250 so this is the initial invested amount

(1+\dfrac{0.08}{12})^{12}=(1+\dfrac{8\%}{12})^{12}

is to compute 8% annual interest compounded monthly (there are 12 months in a year)

and then multiply by 4 means that it is computed for 4 years so

finally the answer is

$250 is invested at 8% annual interest compounded monthly for 4 years

hope this helps

Answer:

c. 10 cm

Step-by-step explanation:

The parallel sides of trapizium are the bases so

base 1(B1) =9cm , base(B2)= 12cm

area(a) = 105 {cm}^{2}

the perpendicular distance means the height so lets find the height

area of trapizium= <u>B1 + B2</u> × h

<u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u>2

{105cm}^{2}(the \: given \: area)  =  \frac{9cm(the \: given \: base) + 12cm(the \: given \: base)}{2}  \times h

{105cm}^{2}  =  \frac{21cm}{2}  \times h

now we crisscross

{105cm}^{2} \times 2 = 21cm \times h

{210cm}^{2}  = 21cm \times h

\frac{ {210cm}^{2} }{21cm}  =  \frac{21cm \: }{21cm}  \times h

h = 10 cm

hope u like it ‍❤️‍‍❤️‍‍❤️‍
