15. Write a function rule that represents y is 5 less than the product of 4 and x.
16. Write a function rule that represents 7 less than three fifths of b is a.
17. Write a function rule that represents the almond extract a remaining in an 8 oz bottle decrease by 1/6 oz for each batch of waffle cookies made.
18. A helicopter hovers 40 ft above the ground. Then the helicopter climbs at a rate of 21 ft/s. Write a rule that represents the helicopter’s height h above the ground as a function of time t. What is the helicopter’s height after 45 s. THis is Urgent i get help
well im late but here are the answers :
15. y = 4x - 5
16. 3/5b - 7 = a
17. a = 8 - 1/6b
18. rule: h = 40 + 21t, then replace the t with 45 to get the height after 45 secs (985)
god bless :) 1 John 4:16 “…we have come to know and to believe the love that God has for us. God is love, and whoever abides in love abides in God, and God abides in him.”
really..... damon ...... really.
¯\_(ツ)_/¯ is right.
15. The function rule that represents y is 5 less than the product of 4 and x can be written as:
y = (4x) - 5
16. The function rule that represents 7 less than three fifths of b is a can be written as:
a = (3/5)b - 7
17. The function rule that represents the almond extract a remaining in an 8 oz bottle decreasing by 1/6 oz for each batch of waffle cookies made can be written as:
a = 8 - (1/6)w
This assumes that the initial amount of almond extract is 8 oz and that each batch of waffle cookies uses 1/6 oz of almond extract.
18. The rule that represents the helicopter's height h above the ground as a function of time t can be written as:
h = 40 + 21t
For this rule, since the helicopter starts 40 ft above the ground and climbs at a rate of 21 ft/s, the height at any given time t can be found by adding 21 times the number of seconds elapsed to the initial height of 40 ft.
To find the helicopter's height after 45 seconds, we can substitute t = 45 into the function:
h = 40 + 21(45)
h = 40 + 945
h = 985
Therefore, the helicopter's height after 45 seconds is 985 ft above the ground.
15. The function rule that represents y is 5 less than the product of 4 and x can be written as follows:
y = 4x - 5
To obtain this function rule, we start by identifying the key information given in the question: the product of 4 and x. Since the problem states that y is 5 less than this product, we subtract 5 from 4x to account for the decrease.
16. The function rule that represents 7 less than three fifths of b is a can be written as follows:
a = (3/5)b - 7
To obtain this function rule, we start with three fifths of b, which is represented as (3/5)b. Since the problem states that a is 7 less than this value, we subtract 7 from (3/5)b.
17. The function rule that represents the almond extract a remaining in an 8 oz bottle decreasing by 1/6 oz for each batch of waffle cookies made can be written as follows:
a = 8 - (1/6)w
To obtain this function rule, we start with the initial amount of almond extract in the bottle, which is 8 oz. For each batch of waffle cookies made, the amount of almond extract decreases by 1/6 oz, so we subtract (1/6)w from the initial amount.
18. The rule that represents the helicopter's height h above the ground as a function of time t can be written as follows:
h = 40 + 21t
To obtain this function rule, we start with the initial height of the helicopter, which is 40 ft. The helicopter is climbing at a rate of 21 ft/s, so for each second that passes (t), the height increases by 21t. We add this to the initial height to calculate the helicopter's height at any given time.
To find the helicopter's height after 45 seconds, we plug t=45 into the function:
h = 40 + 21(45)
h = 40 + 945
h = 985 ft
Therefore, the helicopter's height after 45 seconds is 985 feet.
You have to try yourself and post your attempt.
