Step-by-step explanation:
The height of a projectile that is thrown upward from ground level with an initial velocity of 98 meters per second can be modeled by the equation h = −4.9t2 + 98t, where h is the height in meters and t is the elapsed time in seconds. Find the time it takes for the projectile to hit the ground.
10 seconds
20 seconds
15 seconds
5 seconds
It is found that the time it takes for the projectile to hit the ground would be after 20 seconds.
When does the projectile hit the ground?The projectile would hit the ground when its height h(t), is equal to zero.
The given function that models its height is given by:
[tex]h(t) = -4.9t^2 + 98t.[/tex]
where h is the height in meters and t is the elapsed time in seconds.
Then,
h(t) = 0
[tex]-4.9t^2 + 98t = 0\\-4.9t(t - 20) = 0\\\\t - 20 = 0[/tex]
t = 20
Thus, The projectile hits the ground after 20 seconds.

Faleye Consulting is deciding which of two computer systems to purchase. It can purchase state-of-the-art equipment (System A) for an after-tax cost of $19,000, which will generate after-tax cash flows of $6,000 at the end of each of the next 6 years. Alternatively, the company can purchase equipment with an after-tax cost of $13,000 that can be used for 3 years and will generate after-tax cash flows of $6,000 at the end of each year (System B). If the company’s WACC is 10% and both “projects” can be repeated indefinitely, which system should be chosen, and what is its EAA? Do not round intermediate calculations. Round your answer to the nearest cent.
Choose Project
-Select-
, whose EAA = $
If Faleye Consulting’s WACC is 10% and both “projects” can be repeated indefinitely, the system that should be chosen is System A, and its EAA is $2,866.91.
What is the EAA of a project?The EAA of a project is the Equivalent Annual Annuity. The EAA can be determined using the following formula.
EAA = r x NPV1 - (1 + r)-n
Where the EAA = Equivalent Annual Annuity
r = interest rate per period
n = project duration
NPV = Net present value of project
We can also compute the EAA by using an online finance calculator as follows:
Data and Calculations:System A System B
After-tax cost $19,000 $13,000
After-tax cash flows $6,000 $6,000
Equipment duration 6 years 3 years
WACC = 10%
Annuity factor 4.355 2.487
Present value of cash flows $26,130 $14,922 ($6,000 x 2.487)
NPV $7,130 $1,922 ($14,922 - $13,000)
EAA (an online calculator) $2,866.91 $800.966
Thus, using the EAA rule, the computer system that should be chosen is System A because it has a higher EAA than System B.

What is the explicit formula for this sequence?
-6, -2, 2, 6, 10, ...
Answer:
4n-10, Answer is D
Step-by-step explanation:
First we will use n as any number.
the difference between each of the numbers is +4
This creates first part of the formula.
4n...
If you do 4n and replace n as one (For the first number of the sequence) then 4×1=4. You then have to find out how much you need to add or subtract to get -6 so the difference between 4 and -6 is -10.
This creates the second part of our formula.
4n - 10
You can check this by doing the same thing for the second number and replacing n with 2.
2×4=8
8 - 10= -2 which is the second number in the sequence which confirms this is correct.

Answer:
PQ = 15M = (8.5, 8)Step-by-step explanation:
Given points P(4, 2) and Q(13, 14), you want the length of PQ and its midpoint.
(a) LengthThe length of PQ is given by the distance formula ...
d = √((x2 -x1)² +(y2 -y1)²)
d = ((13 -4)² +(14 -2)²) = √(9² +12²) = √225
d = 15
The length of PQ is 15 units.
(b) MidpointThe midpoint is halfway between the end points. It is conveniently found as the average of the coordinates of the end points.
M = (P +Q)/2
M = ((4, 2) +(13, 14))/2 = (4+13, 2+14)/2 = (17, 16)/2
M = (8.5, 8)
The midpoint of PQ is M(8.5, 8).
__
Additional comment
The length of PQ is the hypotenuse of a right triangle with side lengths 9 and 12 units. You recognize this ratio as 3:4, so the triangle is a 3-4-5 right triangle, scaled up by a factor of 3. The length PQ is 3·5 = 15.
{3, 4, 5} is one of several Pythagorean triples commonly seen in textbook problems. Others include {5, 12, 13}, {7, 24, 25}, {8, 15, 17}.

How many years will it take an account to double in value, assuming a 5.2% interest rate compounded quarterly? Round your answer to the nearest tenth.
The money account is doubled at an interest rate of 5.2 % compunded quarterly, that is, under the model of compound interest in a time period of about 3.5 years.
How to determine the doubling time of money account
The compound interest takes into account the change of money deposited in time in contrast with the simple interest, which only takes the initial amount of money into account. Please notice that four quarters equals a year.
The compound interest formula is described below:
C = C' · (1 + r/100)ⁿ (1)
Where:
r - Interest raten - Number of periodsC' - Initial money amountC - Current money amountIf we know that C = 2 · C' and r = 5.2, then the doubling time is:
n = /㏒ C/C'/㏒ (1 + r/100)
n = ㏒ 2/㏒ 1.052
n ≈ 13.674
The money account is doubled at an interest rate of 5.2 % compunded quarterly, that is, under the model of compound interest in a time period of about 3.5 years. [tex]\blacksquare[/tex]

3x² - 3 ← factor out 3 from each term
= 3(x² - 1²) ← x² - 1 is a difference of squares and factors in general as
a² - b² = (a - b)(a + b)

consider the factors of the constant term (+ 4) which sum to give the coefficient of the x- term (- 5)

If you get 1620 products every 30 seconds, how much would you get in 60 minutes?
Also,
If you get 450 products every 7 seconds, how many would you get in 60 minutes?
Answer:
Step-by-step explanation:
Here,
→We get 1620 products every 30 seconds
→We get 1620/30=54 products in every 1 second
→We get 54×60=3240 products in every 60 seconds(1 minute)
As we have
60seconds=1min
60 minutes=60 seconds ×60
Now,
→We get 3240×60=194400 products in every 60 minutes
Also,
→We get 450 products every 7 seconds
→We get 450/7=64.28 products in every 1 second
→We get 64.28×60 products in every 60 seconds
→We get 3856.8×60=231408 products in 60 minutes

The volumes of two similar figures are given. The surface area of the larger figure is given. Find the surface area of the smaller figure.
V=648 m^3
V=1536 m^3
S.A.=864 m^2
Step-by-step explanation:
the volume of a figure bases always on a calculation that multiplies 3 dimensions.
while a surface area bases always on a calculation that multiplies 2 dimensions.
since the figures are similar, that means that all dimensions or side lengths of one figure correlate to the corresponding dimensions or side lengths of the other figure via the same scale factor f.
and that means that
large side length = small side length × f.
and that means that f has to be multiplied in 3 times for the volume and 2 times for the surface area (once for every dimension).
so,
large volume = small volume × f × f × f =
= small volume × f³
1536 = 648 × f³
f³ = 1536/648 = 64/27
f = 4/3
and
large surface = small surface × f×f =
= small surface × f²
small surface = large surface / f² = 864 / 16/9 =
= 864 × 9/16 = 54 × 9 = 486 m²
7) Find x- intercepts
Answer:
See below:
Step-by-step explanation:
At x axis intercepts, the value of y = 0
0 = -3/5 ( x+7)^2 + 6
-6(-5/3) = (x+7)^2
10 = (x+7)^2
x = -7 +- sqrt (10)
Answer:
[tex] x = -7 \pm \sqrt{10 [/tex]
Step-by-step explanation:
The x-intercepts occur where y = 0.
-3/5(x + 7)² + 6 = 0
-3(x + 7)² + 30 = 0
-3(x² + 14x + 49) + 30 = 0
-3x² - 42x - 147 + 30 = 0
3x² + 42x + 117 = 0
[tex] x = \dfrac{-42 \pm \sqrt{42^2 - 4(3)(117)}}{2(3)} [/tex]
[tex] x = \dfrac{-42 \pm \sqrt{360}}{6} [/tex]
[tex] x = \dfrac{-42 \pm 6\sqrt{10}}{6} [/tex]
