Ann [662]

Answer:

$g(x) = \sqrt[4]{x-7},~ x\geq 7$

Step by step explanation:

$y= f(x) = x^4+7\\\\\text{Replace x with y and solve for y:}\\\\~~~~~~~x = y^4 +7\\\\\implies y^4 = x-7\\\\\implies y = \pm\sqrt[4]{x-7}\\\\ \implies f^{-1}(x) = \pm\sqrt[4]{x-7}$

Ticket Taker Tony collects 90 tickets in 5 minutes. Ticket Taker Tina collects 128 tickets in 8 minutes. Which ticket taker coll

SpyIntel [72]

Answer:

Ticket Taker Tony collects more tickets per minute.

Step-by-step explanation:

In order to find out which ticket taker collects more tickets per minute, you need to solve for how many tickets each Ticket Taker collects per minute to compare. Since 90:5 and 128:8 are different ratios, you need to find the unit rate, or how many tickets each collects per minute. To find unit rate, you divide the numerator by the denominator:

Ticket Taker Tony: $\frac{90 tickets}{5 minutes}$ = $\frac{18 tickets}{1 minute}$

Ticket Taker Tina: $\frac{128 tickets}{8 minutes}$ = $\frac{16 tickets}{1 minute}$

Every minute, Tony collects 18 tickets, while Tina only collects 16, so Ticket Taker Tony collects more.

Answer:

37.5 miles per hour

Step-by-step explanation:

The question might be trying to confuse the reader. Point (1) which states the difference in weight does not show any evidence on how it affects the speed of both cyclist. Point (2) show an important point where the distance traveled is 75 miles.

Cyclist B, who leave point X at 2pm overtook cyclist A at 4pm, showing that the time it took for B to overtook A is 2 hours

Speed = distance / time

= 75 miles / 2 hours

= 37.5 miles per hour
