Jasmine is borrowing $5,200 to purchase her first used car. She can take out a loan
from the car dealership for 42 months at an 8% annual simple interest, or she can
borrow the money from her bank for 36 months at a 7% annual simple interest
rate.
Calculate the interest charged for the car dealership loan.

Answer:
$1456
Step-by-step explanation:
5200 × 8% = $416(interest in 1 yr/12mnths)
42months ÷ 12months(1year) = 3.5 yrs
$416 × 3.5 yrs = $1456(interest in 42mnths/3.5yrs)

Step-by-step explanation:
The height (ft) of an object is launched into the air given by the function h(t)=-6t^2+120t+17 where t is the time in seconds.
When will the obj reach its maximum height ?
What is the max height?
After how many seconds will it hit the ground?
Answer:
Object will reach the max height in 10 seconds.
Max. height is 1817.
It will hit the ground in 20 seconds.
Step-by-step explanation:
In order to find the x value which makes the function take its greatest value, you need to take the derivative of the function and equalize the result to 0.
h'(t)=-12t+120=0
t=10
The object will reach its maximum height in 10 seconds.
h(10) (maximum height) = 6.10.10+120.10+17= 600+1200+17=1817
Considering this is a parabola, time in total is two times more than the time passed until reaching the max. height.

1. Members of a research team are considering three studies related to sleep and learning. The first study involves comparing the scores on a post-study test of learning from two groups of randomly chosen adults, with one group getting at least 7 hours of sleep per night for a week and the other group getting at most 6 hours
of sleep per night for a week. A second study involves asking a random sample of students at a large university to report the average number of hours of sleep they get each night and their college grade point average. A third study involves asking a random sample of high school students in a large school district whether they feel they get enough sleep to stay alert throughout the school day.

A third study involves asking a random sample of high school students in a large school district whether they feel they get enough sleep to stay alert throughout the school day.
Which study appears to look for an association between two variables without actively manipulating either one. What are those variables ?
Solution :
The second study in the context is involved in asking for a random sample of the students at an university to provide a report the average hours of sleep that everybody get each night and also the grade point of their college appears for association between these two variables without actively changing either of one.
These variables are the grade point average of the students and the numbers of hours of sleep.

Last season, Ken made 73% of his free throws. If he attempted 59 free throws all season, estimate how many free throws he made. F 15 H 45 G 38 J 60
Answer:
H 45
Step-by-step explanation:
Given data
Total number of free throws= 59
he made 79%
Hence the number of throws made
=79/100*59
=0.79*59
=46.61
Approximately he made 45 of the throws

what is the median of this data set?
16,21,28,30,34,45,58,60
Answer:
32
Step-by-step explanation:
the median in a data set is the middle number. first, you are going to want to order the numbers in numerical order.
this is what it would look like.
16, 21, 28, 30, 34, 45, 58, 60
(basically how it is in the problem lol)
since there's an even number of numbers in the set, you have to take the mean of the two middle numbers. in this case, the two middle numbers are 30 and 34.
you take the mean of numbers by adding them, and then dividing them based on the number of numbers. (sorry if that doesn't make sense, just look down ehe)
(30+34)/2
we divide by two because there are two numbers.
(30+34)/2
(64)/2
32if this didn't make sense - sorry - but you can watch this video: https://www.khanacademy.org/math/cc-sixth-grade-math/cc-6th-data-statistics/mean-and-median/v/mean-median-and-mode

Answer:
x=33
Step-by-step explanation:
1) write the equation: 180=90+(x+15)+(x+9)
2) subtract 90 on both sides and add x+15 and x+9 together: 90=2x+24
3) subtract 24 from both sides: 66=2x
4) divide both sides by 2: x=33
In right triangle ABC, m∠ B ≠ m∠ C. Let sin B = r and cos B = s.
What is sin C – cos C?
Draw and label a diagram.
sin A = CB / AB
cos B = CB / AB
sin A = cos B
2x - 1.3 = 5x
Can you solve for x and answer?
The value of expression sin C - cos C is,
⇒ r - s
What is mean by Triangle?Triangle is a three sided polygon, which has three vertices and three angles and which has sum 180 degrees.
Given that;
In right triangle ABC,
⇒ m∠ B ≠ m∠ C.
Let us assume that,
⇒ sin B = r
And, cos B = s.
Now, We get;
sin B = rh / h
= r
And, cos B = sh / h
= s
Hence, We can formulate;
sin C = sh / h = s
cos C = rh / h = r
Thus, We get;
⇒ sin C - cos C
⇒ r - s
Therefore, The value of expression sin C - cos C is,
⇒ r - s

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.
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.
