f. Would you still use the same domain and range? Why or why not?
Answer:
a) The domain of the function is . , , b)The range of the function is . , , c) The ball is 73 meters off of the ground at x = 3 seconds.Step-by-step explanation:The complete statement is: A ball is thrown upward off of a 100 meter cliff with an initial velocity of 6 m/s. The function represents this situation where x is time and y is the distance off of the ground. a) What domain does the function make sense? b) What range does the function make sense ? c) How far off the ground is the ball at time x = 3 seconds?a) Let and be the time, measured in seconds, and the distance of the ground, measured in meters, respectively. Time is a positive variable, so domain corresponds to the interval when and . That is: Therefore, the domain of the function is . , b) The distance off of the ground is also a positive variable, where ball is thrown upward at a height of 100 meters and hits the ground at a height of 0 meters. Hence, the range of the function is . , c) The distance of the ball off of the ground at x = 3 seconds is found by evaluating the function:The ball is 73 meters off of the ground at x = 3 seconds.
Step-by-step explanation:
Answer: $40 would be the minimal cost that both shops share. Six roses and a vase gets $40 from Gabe’s shop, while one rose and a vase gets $40 from Livingston.
Step-by-step explanation:
Livingston florist:
1 Rose + vase = $40.
($1) + ($39)
Gabe’s Flowers:
1 Rose + vase = $30.
($2) + ($28)
We’re trying to get x (x=$2 • amount + vase)...
We know that $2 • 6 = $12...
The cost of the vase from Gabe’s shop is $28.
$28 + 12 = $40.
$40 contains six roses from Gabe’s shop (plus vase.)
$40 contains one rose from Livingston (plus vase).
Hope this helps!
Answer: she/he is right
the answer is 2:1
Step-by-step explanation:
y = 30 + 40x
x = 40 + 30y
x = 40 +30y
y = 40 + 30x
Answer:
y = 40 + 30x
Step-by-step explanation:
You dont know how many houses, so you put a variable for it. You have $40 in your wallet. Thats why y = 40 + 30x is your answer.
Number of candy bars sold by girls altogether is 91
Given that The ratio of candy bars sold by Anna, Elisa and Tiara are 2 to 4 to 7
So ratio of candy bars sold by Anna, Elisa and Tiara = 2 : 4 : 7
Let the candy bars sold by Anna be 2a
Let the candy bars sold by Elisa be 4a
Let the candy bars sold by Tiara be 7a
Given that Elisa has sold 28 candy bars
Number of candy bars sold by Elisa = 28
4a = 28
a = 7
So we have found "a" as 7
Thus we get,
candy bars sold by Anna = 2a = 2(7) = 14
candy bars sold by Elisa = 4a = 4(7) = 28
candy bars sold by Tiara = 7a = 7(7) = 49
We have to find the number of candy bars sold by girls altogether
number of candy bars sold by girls altogether = candy bars sold by Anna + candy bars sold by Elisa + candy bars sold by Tiara
number of candy bars sold by girls altogether = 14 + 28 + 49 = 91
So altogether girls sold 91 candies
