A plant is 3 inches tall when you purchase it and grows 2 inches per month. Write an equation in slope intercept form that repre
tresset_1 [31]

Answer:

y = 3 + 2x

Step-by-step explanation:

In this scenario, we are given two values which are the initial height of the plant and its growth height. Then we are given a variable which is the number of months (x) that are unknown for us. The growth height needs to be multiplied by the number of months to know how much it has grown in that time period. Then we add this value to the initial height of the plant to calculate the total height (y) of the plant after x number of months. We can apply this information to form the following equation in slope-intercept form.

y = 3 + 2x

Two balls are drawn in succession out of a box containing 4 red and 3 white balls. Find the probability that at least 1 ball was
kifflom [539]

Answer:

A) 40/49

B) 36/42

Step-by-step explanation:

Given:

Red Balls, R : 4

White Balls, W : 3

Total Balls : 3+4=7 balls

A) If balls were replaced before the 2nd draw

P (White) = 3/7; P(Red) = 4

P(at least 1 red ball),

= 1 - P(no red balls)

= 1  - P(White, White)

= 1 - (3/7)(3/7)

= 1-(9/49)

= 40/49

A) If balls were replaced before the 2nd draw

P(1st White Ball) = 3/7 ; P(2nd White Ball) = 2/6

P(at least 1 red ball),

= 1 - P(no red balls)

= 1  - P(1st White, 2nd White)

= 1 - (3/7)(2/6)

= 1 - 6/42

= 36/42

A football is kicked vertically upward from a height of 4 feet with an initial speed of 65 feet per second. The formula h=4+65t−
KATRIN_1 [288]

Answer: h = 70ft

Step-by-step explanation: To find the height the ball reached after 2 seconds, substitute variable t for 2 and calculate height:

h=4+65t-16t^{2}

h=4+65.2-16.2^{2}

h=4+65.2-16.4

h=4+130-64

h = 70

<u>After 2s, the football reached a height of </u><u>70 feet</u><u>.</u>
