Answer:
C. If an object is dropped from a height of 120 feet, the function h(t) = –16t2 – 120 gives the height of the object after t seconds.
Step-by-step explanation:
.................................The last one is the only one that makes sense according to the standard position function. -16t^2 is the pull of gravity on an object in free fall, and the height is 120 feet above the ground. Hopefully that's what you need since there's no graph we can refer to
....................................................Answer:
The explanation that best provides the real-world scenario is:
If an object is dropped from a height of 120 feet, the function
gives the height of the object after t seconds.
Step-by-step explanation:
a)
If an object is dropped from a height of 120 feet, the function gives the height of the object after t seconds.
This option is incorrect.
Since when t=0 we have:
h(t)= -120
This is not possible as the object is above the ground and hence must have positive height initially.
b)
If an object is dropped from a height of -16 feet, the function gives the height of the object after t seconds.
This option is incorrect.
Since a object when is dropped from some height then it must be a positive height.
Also, when t=0 we have: h(t)= 120 feet.
This means that the object is dropped from a height of 120 feet.
c)
If an object is dropped from a height of 120 feet, the function gives the height of the object after t seconds.
In this when t=0 we have:
h(t)=120 that means the height of the object initially was 120 feet and then it decreases with the increase in time as the object will reach the ground with the time increase and hence height will decrease.
Hence, this option is correct.
........................................The equation that models the movement of the object is:
Where,
t: time
a: acceleration due to gravity
v0: initial speed
h0: initial height
Suppose that the object falls with zero initial velocity and from a height of 38 feet.
The equation that models the problem is:
Answer:
If an object is dropped from a height of 38 feet, the function h (t) = -16t2 + 38 gives the height of the object after seconds
.................Answer: If an object is dropped from a height of 38 feet, the function h (t) = -16t2 + 38 gives the height of the object after seconds
Step-by-step explanation:
The explanation that best provides the real-world scenario is:
⇒ If an object is dropped from a height of 120 feet, the function
h(t) = - 16t² - 120 gives the height of the object after t seconds.
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
a) If an object is dropped from a height of 120 feet, the function
h(t) = - 16t² + 120 gives the height of the object after t seconds.
Hence, This option is incorrect.
Since, when t=0 we have:
h (t) = -120
This is not possible as the object is above the ground and hence must have positive height initially.
b) If an object is dropped from a height of -16 feet, the function
h(t) = - 16t² + 120 gives the height of the object after t seconds.
This option is incorrect.
Since a object when is dropped from some height then it must be a positive height.
Also, when t = 0
we have: h (t) = 120 feet.
This means that the object is dropped from a height of 120 feet.
c) If an object is dropped from a height of 120 feet, the function
h(t) = - 16t² - 120 gives the height of the object after t seconds.
In this when t=0 we have:
h(t)=120
That means the height of the object initially was 120 feet and then it decreases with the increase in time as the object will reach the ground with the time increase and hence height will decrease.
Hence, this option is correct.

Dorian buys one 32-ounce can of purple paint witha red to blue ratio of 3 to 5. He buys a 25-ouncee can of a different shade of purple paintwith a red to blue ratio of 3 to 2. Dorian mixes the two cans together. What is the ratioof red paint to blue paint in Dorian's new mixture?
Answer:
9 : 10
Step-by-step explanation:
For 32 ounce- can
Dorian buys one 32-ounce can of purple paint with a red to blue ratio of 3 to 5.
The sum of proportion = 3 + 5 = 8
The number of ounces of red paint = 3/8 × 32-ounce = 12 ounces
The number of ounces of blue paint = 5/8 × 32-ounce = 20 ounces
For 25 ounce can
He buys a 25-ounce can of a different shade of purple paint with a red to blue ratio of 3 to 2.
The sum of proportion = 3 + 2 = 5
The number of ounces of red paint = 3/5 × 25-ounce = 15 ounces
The number of ounces of blue paint = 2/5 × 25-ounce = 10 ounces
Dorian mixes the two cans together.
The total ounces for red paint
= 12 ounces + 15 ounces = 27 ounces
The total ounces for blue paint
= 20 ounces + 10 ounces = 30 ounces
Hence, the ratio of red paint to blue paint in Dorian's new mixture is
Red : Blue
27 ounces : 30 ounces

Answer:
y = 51.32º
Step-by-step explanation:
z = 180 - 47 - 90
z = 43º

solve 3x-y=7 for x if weird answer will report
Answer:
x = 1/3y +7/3
Step-by-step explanation:
3x-y=7
Add y to each side
3x-y+y=7+y
3x = y+7
Divide each side by 3
3x/3 = y/3 + 7/3
x = 1/3y +7/3
Answer:
x= 7/3 + y/3
Step-by-step explanation:
divide each term by 3 and simplify

Am stunned on how you can't do 5th grade math and you appear in High School... But I'll help
According to PEMDAS (Parenthesis, Exponents, Multiplication/Division, and Addition/Subtraction) you wanna do 5-9+18 first. That gives you 14. After 14, you do 14/7 which gives you 2. And finally, you do 24 - 2 which gives you 22.

Answer:
Mode :6 Range :5
Step-by-step explanation
To find the mode look for the number that is repeated the most times. And to find the range subtract the greatest number with the smallest number. Hope this helped :)
Step-by-step explanation
The range is the max value minus the minimum value, which would be 8-3, and that equals 5
and the mode is the number that you see the most in a data set, in this case the mode would be 6 since it is the only number that occurs three times

Calculate the interquartile range from the given box plot
Answer:
IQR = 3
Step-by-step explanation:
The interquartile range (IQR) is the difference between the upper quartile Q₃ and the lower quartile Q₁
Q₃ is the value at the right side of the box , that is Q₃ = 62.5
Q₁ is the value at the left side of the box. that is Q₁ = 59.5
Then
IQR = Q₃ - Q₁ = 62.5 - 59.5 = 3
