Answer:
3rd option
Step-by-step explanation:
[tex]\frac{3x^2-3}{x^2-5x+4}[/tex] ( factorise numerator and denominator )
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)
x² - 1
= x² - 1²
= (x - 1)(x + 1) , then
3x² - 3 = 3²(x - 1)(x + 1) ← in factored form
--------------------------------
x² - 5x + 4
consider the factors of the constant term (+ 4) which sum to give the coefficient of the x- term (- 5)
the factors are - 1 and - 4 , since
- 1 × - 4 = + 4 and - 1 - 4 = - 5 , then
x² - 5x + 4 = (x - 1)(x - 4)
then
[tex]\frac{3x^2-3}{x^2-5x+4}[/tex] = [tex]\frac{3(x-1)(x+1)}{(x-1)(x-4)}[/tex] ← in factored form

7-ounce package costs $2.38. A
15-ounce package costs $5.25. A
26-ounce package costs $8.58. Which
package is the best buy?
Answer:
Step-by-step explanation:
Remark
If you find out the cost of 1 oz of each of them, that will determine the best buy. The smallest number is the best buy.
Givens
7 oz cost $2.38
15 oz cost $5.25
26 oz cost $8.58
Solution
7 oz7 oz cost $2.38
1 oz cost x This is a proportion. 3 quatities are known. Find x Cross multiply.
7/1 = 2.38/x
7x = 2.38
x = $0.34 dollars
15 oz15 oz cost 5.25
1 oz costs x
15.1/1 = 5,25 x Cross Multiply
15x = 5.25 * 1 Divide by 15
x = 5.25 / 15
x = $0.35
26 oz26 oz cost 8.58
1 oz cost x
26/1 = 8.38/x Cross Multiply
26x = 8.38 Divide by 26
x = 8.38/20
x = 0.32 dollars
Answer
7 oz cost 0.34
15 oz cost 0.35
26 oz cost 0.32
The best buy is 0.32 / oz for 26 ozI don't know the answer marked stylish random

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.

A person looking out a window, 40 feet above street level can sight the top and
bottom of the building. The angle of elevation to the top of the building is 61 degrees and the angle
f depression to the bottom of the building is 37 degrees. How tall is the building that the person is looking at
Answer:
135.94 feet
Step-by-step explanation:
Split the problem into two parts :
Distance between viewer and buildingHeight of the top part of the buildingDistance between viewer and building
The lower part of the building is 40 feet, as it is mentioned the viewer is 40 feet above street levelLet the distance be called 'd'Therefore, tan37° = 40/dtan37° = 3/4 = 0.75⇒ 40/d = 0.75⇒ d = 40/(3/4) = 40 x 4/3 = 160/3 = 53.3 feetHeight of the top part of the building
Let the height of the top part be 'h'Therefore, tan61° = h/d = h/53.3tan61° = 1.8⇒ h/53.3 = 1.8⇒ h = 53.3 x 1.8 = 95.94 feetTotal height of building

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.

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

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]

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}.
