Answer: 14.48000 . . . ≤ t < 15.0000

Step-by-step explanation:

"Truncated by a hundreths of a second" means that the time was rounded to the nearest 0.0X second. That would mean the reported time of 14.48 seconds was shortened from a time period having more digits to the right. For example, If the time were actually 14.48223 seconds, the time was truncated to just 14.48 seconds. The term used here. truncated, means that the digits after the hunredth place are simply dropped. It doesn't say rounded, just truncated. Brutal. So that would mean that times between 14.48000 . . . and 14.48999 . . . would all be reported as 14.48 seconds.

So the time could actually be 14.48000 . . . ≤ t < 15.0000

By how much would the quantity of labor demanded decrease if a minimum wage hike raised prevailing wages from $8 to $10 an hour

Mademuasel [1]

Answer:

it would decrease by 10%

Step-by-step explanation:

Price elasticity of demand measures the responsiveness of quantity demanded to changes in price of the good.

Price elasticity of demand = percentage change in quantity demanded / percentage change in price

percentage change in price = ($10 - $8) / $8 = 0.25 x 100 = 25%

0.4 = percentage change in quantity demanded / 25%

percentage change in quantity demanded = 25% x 0.4 = 10%

Mercury is the closest planet to the sun at a distance of 36 million miles. The closest star to the sun is Proxima Centauri, whi

SpyIntel [72]

Answer:

2.36 * 10^13 miles

Step-by-step explanation:

Given that :

Proxima centauri is at a distance of 4.24 light years away from the sun.

Distance in miles of Proxima centauri from the sun ;

1 light year = 5.9 * 10^12 miles

Number of light years from the sun * 5.9 * 10^12

= 4 * (5.9 * 10^12)

= 23.6 * 10^12 miles

= 2.36 * 10^13 miles

Given that f(x) = 10x + 45, find f(7)

sattari [20]

Answer:

$\boxed{\bf f(x) = 115}$

Step-by-step explanation:

<u>Given polynomial </u><u>function </u>:-

$f(x) = 10x + 45$

<u>To </u><u>find</u> :-

$\sf \: f(7)$

<u>Solution:-</u>

$\sf \implies \: f(x) = 10x + 45$

Here, the value of x is 7(given).

So, <u>Substitute the value of x on the RHS and </u><u>on </u><u>LHS </u>:-

$\sf \implies{f}(“7”) = 10(“7”) + 45$

Simplify the RHS:-

<u>Multiply 10 and 7 :-</u>

$\sf \implies{f}(7) = 10 \times 7 + 45$

$\sf \implies{f}(7) = 70 + 45$

<u>Add 70 and 45 :-</u>

$\sf \implies{f}(7) = 115$

We're done!

Hence, the value of f(7) would be,

$\sf \implies{f}(7) = 115$

$\rule{225pt}{2pt}$

I hope this helps!

Let me know if you have any questions.
