Bailey bought a lawnmower for $600. The value of the lawnmower depreciates 2% every year. What is the value of the lawnmower aft

givi [52]

Answer:

$542

Step-by-step explanation:

we know that

The equation of a exponential decay function is given by

$y=a(1-r)^x$

where

y is the value of the lawnmower

x is the time in years

a is the initial value

r is the rate of change

we have

$a=\$600\\r=2\%=2/100=0.02$

substitute

$y=600(1-0.02)^x$

$y=600(0.98)^x$

For x=5 years

$y=600(0.98)^5=\$542$

The triangles are similar. If DE=32, EF=24,and BC=6, find AB

Karolina [17]

ABC = DEF
AB = DE , AC = DF & BC = EF ( means similar )
EF = 4times BC
So, the triangle DEF is 4times the triangle ABC
EF = 24 and BC = 6
So, AB = DE/4 = 32/4 = 8

Tayler tried to evaluate the expression (22-5\times3) + 6(22−5×3)+6left parenthesis, 22, minus, 5, times, 3, right parenthesis,

kramer

Step-by-step explanation:

Given the expression that Tayler tried to evaluate as:

$(22-5\times3) + 6$

We will solve this equation using PEDMAS

Multiplication before addition and subtraction

On solving:

$Step \ 1\\= (22-5\times3) + 6\\= (22-(15)) + 6\\\\Step\ 2\\= (22-15) + 6\\\\Step \ 3\\= 7+6\\= 13$

From the steps above, we can see that Tayler made an error in step 3 by taking the difference of 7 and 6 and arriving at 1 instead of summing up to get 13 as shown above.

I don’t understand this!

Korvikt [17]

Answer:

635

Step-by-step explanation:

so basically you need to make an equation to find out what number, when put through all of those operations, will still equal the same number in the end. the way you do that is with an equation. so let's say our starting number is <em>x</em>, since we don't know its value yet.

the final equation is (((((((x/5)+6)/7)-8)9)+114)3)-4 = x

basically it's just x, all those different operations in that order, which is why you need parentheses, equals to x again because it's the same in the end. when you solve that you get 635
