11. Write the equation of a parabola that matches each description. a) The graph of y = x^2 is reflected about the x-axis and then translated 5 units up. b) The graph of y = x^2 is stretched vertically by a factor of 5 and then translated 2 units left. c) The graph of y = x^2 is compressed vertically by a factor of 1/5 and then translated 6 units down. d) The graph of y = x^2 is reflected about the x-axis, stretched vertically by a factor of 6, translated 3 units right, and translated 4 units up.

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.  

13

step-by-step explanation:

divide the cost of the total of sodas you bought by the cost of one soda, for example:

$24.57 divided by $1.89 is 13 which means you bought 13 sodas

hello,

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.
