Answer:

For 10. the answer is 0, and 150 miles (assuming the 25 is in miles per hour)

For 11. the answer is 0, and 22.5 tacos

Step-by-step explanation:

Rate of change is equal to the change y over the change in x, or in this case, the change in speed over the change in time, because the rate for both problems is "constant", there is no change in speed. To find the number of miles driven you need to multiply the time passed (6 hours) by the speed (25 mph), 6 x 25 = 150. The number of tacos eaten is times passed (9 minutes) multiplied by the speed he is eating tacos (2.5 tacos per minute), 2.5 x 9 = 22.5. Hope this helps!

approximate each irrational number to the nearest hundredth without using a calculator square root of 118 and 319

Strike441 [17]

Answer:

$\sqrt{118}\approx 10.86$

$\sqrt{319}\approx 17.86$

Step-by-step explanation:

Consider the provided number.

We need to find the approximate value of $\sqrt{118}$ to the nearest hundredth.

First find two perfect squares that the irrational number falls between.

$100$

118 is lying between 100 and 121, therefore the square root value of 118 will be somewhere between 10 and 11.

$\sqrt{100}$

$10$

118 is closer to 121 as compare to 100.

Therefore, $\sqrt{118}\approx 10.86$

Consider the number $\sqrt{319}$

First find two perfect squares that the irrational number falls between.

$289$

319 is lying between 289 and 324, therefore the square root value of 319 will be somewhere between 17 and 18.

$\sqrt{289}$

$17$

319 is closer to 324 as compare to 289.

Therefore, $\sqrt{319}\approx 17.86$

I need this ASAP!!<br><br><br> calculate the rate of change on this graph

Vilka [71]

Answer: The slope is 2

Step-by-step explanation: For questions like these, find 2 points on the graph that are on whole numbers, for example (10,60) and (20,80). Then use the formula y2-y1/x2-x1 to solve for the slope, which would be the same thing as rate of change. 80-60/20-10 which equals 2. The slope would be 2.
