Describe how the graph of y = −4x2 differs from the graph of y = −x2 . a. the graph of y = −x2 is narrower than the graph of y = −4x2. b. the graph of y = −4x2 is narrower than the graph of y = −x2. c. the graph of y = −4x2 is the same as the graph of y = −x2 but shifted down by 4 units. d. the graph of y = −4x2 opens upward while the graph of y = −x2 opens downward.

26 is 33.33% of 78

step-by-step explanation:

26 is what percent of 78?

26 is p% of 78

equation: y = p% * x

solving our equation for p

p% = y/x

p% = 26/78

p = 0.3333

convert decimal to percent:

p% = 0.3333 * 100 = 33.33%

45.36 feet per second

step-by-step explanation:

tyrone travels 30 miles in 58.2 minutes.  

1 mile = 5280 feet; this means he travels

30(5280) = 158400 feet in 58.2 minutes.

1 minute = 60 seconds; this means he travels 158400 feet in

58.2(60) = 3492 seconds.

this gives us the unit rate of

158400/3492 = 45.36 feet per second.
