i need help please!!!!!!!
Devin jumped off a cliff into the ocean in Acapulco while vacationing with his family. His height as a function of time could be modeled by the function h(t)= -16t square root 2 +16t +96, where T is the time in seconds and H is the time in feet. How many seconds until Devon hit the water? Around to the nearest tenth is necessary.
Answer:
3 seconds
Step-by-step explanation:
Given the height modelled by the function
h(t) = -16t² + 16t + 96
The hit the water at h(t) = 0
0 = -16t² + 16t + 96
Divide through b y -16
0 = t² - t - 6
t² - t - 6 = 0
t² - 3t+2t - 6 = 0
t(t-3)+2(t-3) = 0
t+ 2 = 0 and t - 3 = 0
t = -2 secs and t = 3secs
Since t can't be negative, hence;
t = 3 secs
hence it will take 3 seconds until Devon hit the water
The difference between two numbers is 3.50. The lesser number is 1.65.
What is the other number? _____
Answer:
Let the required number be x.
According to the problem,
x-1.65=3.50 => x= 1.65+3.50 => x=5.15
5.15 is the right answer.Can someone pleaseeee help if you’re correct I’ll give u brainlist

Select the correct answer for each statement Will yield consecutive odd integers Will yield consecutive integers
Complete question :
Select the correct answer for each statement.
1.) Will yield consecutive odd integers.
k+10, k+12, k+14
or
k+2, k+3, k+4
2.) Will yield consecutive integers.
k+1, k+2, k+3
or
k+6, k+8, k+10
Answer:
Consecutive odd integer : k+10, k+12, k+14
Consecutive integers : k+1, k+2, k+3
Step-by-step explanation:
Odd integers are numbers which aren't divisible by 2 ; such as : 1, 3, 5, 7, 9, 11,... The series continues in that manner. Consecutive odd integers have a common difference of 2, just as indicated in the instance given ; 1, 3, 5, 7, 9, 11,...
Therefore a series with a difference of 2 is more likely to be one representing consecutive odd integers.
2.) for concmsecutive integers :
Consecutive integers have a common difference of 1 between each successive integer ;
Hence, k+1, k+2, k+3 will most likely represent consecutive integers since the value of k is the same.
Suppose r(t) = (et cos t)i + (et sin t)j. Show that the angle between r and a never changes. What is the angle?
Answer:
Angle = Ф = [tex]cos^{-1}[/tex](0) = 0
Hence, it is proved that angle between position vector r and acceleration vector a = 0 and is it never changes.
Step-by-step explanation:
Given vector r(t) = [tex]e^{t}cost i + e^{t}sint j[/tex]
As we know that,
velocity vector = v = [tex]\frac{dr}{dt}[/tex]
Implies that
velocity vector = [tex](e^{t} cost - e^{t} sint)i + (e^{t} sint - e^{t}cost )j[/tex]
As acceleration is velocity over time so:
acceleration vector = a = [tex]\frac{dv}{dt}[/tex]
Implies that
vector a =
[tex](e^{t}cost - e^{t}sint - e^{t}sint - e^{t}cost )i + ( e^{t}sint + e^{t}cost + e^{t}cost - e^{t}sint )j[/tex]
vector a = [tex](-2e^{t}sint) i + ( 2e^{t}cost)j[/tex]
Now scalar product of position vector r and acceleration vector a:
r. a = [tex]<e^{t}cost, e^{t}sint> . <-2e^{t}sint, 2e^{t}cost>\\[/tex]
r.a = [tex]-2e^{2t}sintcost + 2e^{2t}sintcost[/tex]
r.a = 0
Now, for angle between position vector r and acceleration vector a is given by:
cosФ = [tex]\frac{r.a}{|r|.|a|}[/tex] = [tex]\frac{0}{|r|.|a|} = 0[/tex]
Ф = [tex]cos^{-1}[/tex](0) = 0
Hence, it is proved that angle between position vector r and acceleration vector a = 0 and is it never changes.
Which is the first INCORRECT step in the solution below?
Solve: 3 – 2(x + 6) = x + 6
Step 1: 3 – 2x – 12 = x + 6
Step 2: 15 – 2x = x + 6
Step 3: 15 = 3x + 6
Step 4: 9 = 3x
Answer:
its is step 2
Step-by-step explanation:
the correct step is 3-2x-12=x+6
9-2x=x+6
9=3X+6
3=3x

Write the equation of a line that is perpendicular to y=7/5x+ 6 and that passes through the point (2,-6).
Given that,
The equation of line is y=7/5x+ 6 and that passes through the point (2,-6).
To find,
The equation of line that is perpendicular to the given line.
Solution,
The given line is :
y=7/5x+ 6
The slope of this line = 7/5
For two perpendicular lines, the product of slopes of two lines is :
[tex]m_1m_2=-1\\\\m_2=\dfrac{-1}{7/5}\\\\=\dfrac{-5}{7}[/tex]
Equation will be :
y=-5x/7+ b
Now finding the value of b. As it passes through (2,-6). The equation of line will be :
[tex]-6=\dfrac{-5}{7}(2)+b\\\\ -6=\dfrac{-10}{7}+b\\\\b=-6+\dfrac{10}{7}\\\\b=\dfrac{-32}{7}[/tex]
So, the required equation of line is :
y=-5x/7+ (-32/7)
[tex]y=\dfrac{-5x}{7}-\dfrac{-32}{7}[/tex]

It has been projected that the population of a certain city in the southwest will increase by 6 percent during each of the next 5 years if the current population is 190,000 what is the expected population in 5 years
Answer: 254,263 people
Step-by-step explanation:
The current population of the town is 190,000.
This population is going to increase by 6% every year for 5 years.
In 5 years therefore, the population of the town is expected to be:
You should use the compound interest formula:
= Initial population * ( 1 + rate of increase) ^ number of years
= 190,000 * (1 + 6%)⁵
= 190,000 * 1.3382255776
= 254,262.859744
= 254,263 people
