suppose you lean out a window of a tall building and use a sling to launch a stone straight up. the stone starts with a velocity of 69 feet per second. it leaves the sling 365 feet above the ground.
Answers
Answer:
y= 69x + 356
Step-by-step explanation:
y= 69x + 356
It goes 69 feet per second hence the 69x and it starts 356 feet in the air
The height of the stone above the ground at any time t can be described by the quadratic function h(t) = -16t^2 + 69t + 365.
How to write a function?Assuming that the acceleration due to gravity is -32 feet per second squared (neglecting air resistance), we can use the following kinematic equation to describe the height of the stone as a function of time:
h(t) = -16t²+ vt + h₀
where:
h(t) is the height of the stone above the ground at time t
v is the initial velocity of the stone (69 feet per second, in this case)
h₀ is the initial height of the stone (365 feet above the ground, in this case)
Substituting the values of v and h0, we get:
h(t) = -16t² + 69t + 365
Therefore, the height of the stone above the ground at any time t can be described by the quadratic function h(t) = -16t² + 69t + 365.

5 = 119° because it is an alternate angle to angle 7
6 = 61° because is is an alternate angle to 61°
7 = 119° because it and 61° are supplementary angles (total 180° together)

Suppose you want to treat your office team to lattes at a local coffee shop. The drinks are $4.25 each,
plus you plan to buy a $3 scone for yourself. You also tip the barista 10% and have to pay 8.25% sales tax.
How many lattes can you afford if you have $60 to spend?
Answers
Answer: 10 lattes
lmk if this is incorrect
Step-by-step explanation:
sales tax: 60(.0825)=4.95
tip: 60(.10)=6
scone: 3
total excluding lattes: 4.95+6+3=13.95
total left to spend on lattes: 60-13.95=46.05
amount of lattes you can afford: 46.05/4.25=10.835294.....
Answer:
11 lattes and 1 scone
Step-by-step explanation:
11×4.25= 46.75+3.00= 49.75
49.75×8.25%= $53.85
10% of $53.85 is $5.38
53.85+5.38= $59.23
You will have .77 left

The first sample surveyed 15 people as they exited the bank on Main Street. The first sample found that the mean number of hours they listened to the radio each month was 20.
The second sample surveyed every sixth person as they exited the only local grocery store until 100 people were surveyed. The second sample found that the mean number of hours they listened to the radio each month was 12.
Which statements are true? Check all that apply.
The second sample is random.
The second sample is likely to be more representative of the population.

1). Volume of the pyramid = [tex]\frac{1}{3}(72)(15)[/tex]
= 360 cm³
2). Volume of the pyramid = [tex]\frac{1}{3}(\text{Area of the triangular base})(\text{Height})[/tex]
Area of the triangular base = [tex]\frac{1}{2}(\text{Base})(\text{height})[/tex]

Therefore, volume of the pyramid = [tex]\frac{1}{3}(20)(12)[/tex]

5). Volume of the cone = [tex]\frac{1}{3}\pi r^{2}h[/tex]
Here, r = radius of the circular base

Volume of the cone = [tex]\frac{1}{3}\pi (2)^2(4)[/tex]
