Helen has been working on a science project about plant growth. Plant A started at a height of 6 cm and exhibited steady growth during the first four weeks of the project. After those four weeks, Plant A was 26.8 cm in height. In a linear model of Plant A's growth, x represents the number of weeks after being planted, and y represents the plant's height [in cm]. Relative to this model, which of the following statements applies? A. An additional 8.2 weeks of growth is associated with an additional centimeter of plant height. B. An additional week of growth is associated with an additional 8.2 cm of plant height. C. An additional 5.2 weeks of growth is associated with an additional centimeter of plant height. D. An additional week of growth is associated with an additional 5.2 cm of plant height.

Marilyn and Tiara went for jogging every day. They increased the number of minutes of jogging every week as described below: Marilyn: Jogged for 10 minutes every day in the first week, 20 minutes in the second week, 40 minutes in the third week, and 80 minutes in the fourth week. Tiara: Jogged for 10 minutes every day in the first week, 20 minutes in the second week, 30 minutes in the third week, and 40 minutes in the fourth week Which statement best describes the methods used by Marilyn and Tiara to increase the time they spent jogging? Marilyn's method is linear because the number of minutes increased by an equal factor every week.Tiara's method is linear because the number of minutes increased by an equal number every week. Both Tiara's and Marilyn's method is exponential because the number of minutes increased by an equal number every week. Both Tiara's and Marilyn's method is exponential because the number of minutes increased by an equal factor every week.

Some of the steps in the derivation of the quadratic formula are shown. Step 4: Step 5: Step 6: Step 7: Which best explains why the expression cannot be rewritten as during the next step? Negative values, like −4ac, do not have a square root. The ± symbol prevents the square root from being evaluated. The square root of terms separated by addition and subtraction cannot be calculated individually. The entire term b2 − 4ac must be divided by 2a before its square root can be determined.

The party planning committee has to determine the number of tables needed for an upcoming event. If a square table can fit 8 people and a round table can fit 6 people, the equation 150 = 8x + 6y represents the number of each type of table needed for 150 people. The variable x represents the number of . The variable y represents the number of . If y = 9, find the value of x. The committee needs square tables.
