the sum of the factors for the middle term must be __
Answer:
Negative

Years of Factoring:
What the problem tells us is that we have:
X^2 - 4x - 3
or something along these lines. If we factor this we get:
(X-4)(X+1)
The bigger inside factor has to be negative for these problems, because the third term is negative.
The sum of the middle term must give a negative value.

In ΔNOP, p = 72 inches, o = 84 inches and ∠O=19°. Find all possible values of ∠P, to the nearest degree
Answer:
16
Step-by-step explanation:
The value of the angle m∠P is given by the law of sines and m∠P = 16°
What is the law of sines?The relationship between a triangle's sides and angles is provided by the Law of Sines. Trigonometry's law of sines can be expressed as a/sinA = b/sinB = c/sinC, where a, b, and c are the lengths of the triangle's sides, and A, B, and C are the triangle's respective opposite angles.
Law of Sines :
a / sin A = b / sin B = c / sin C
Given data ,
Let the triangle be represented as ΔNOP
Now , the measure of side p = 72 inches
The measure of side o = 84 inches
And , the measure of angle ∠O = 19°
From the law of sines , we get
a / sin A = b / sin B
On simplifying , we get
sin p / 72 = sin o / 84
Multiply by 72 on both sides , we get
sin p = ( 72 / 84 ) sin ( 19 )°
On further simplification , we get
sin p = ( 0.857 ) x 0.325568
sin p = 0.279058
Taking inverse on both sides , we get
p = sin ⁻¹ ( 0.279058 )
p = 16.204°
Therefore , the value of p is 16°
Hence , the measure of angle ∠P = 16°

Mohamed wants to buy a television that costs $800, including taxes. To pay for the television, he will use a payment plan that requires him to make a down payment of $200, and then pay $65 each month for 10 months. What is the percent increase from the original cost of the television to the cost of the television using the payment plan?
Answer:
6.25%
Step-by-step explanation:
I'm simply returning the favor.
If the down payment is $200, then we can subtract:
$800 - $200 = $600
Then we can find the "rent" times ten, then subtract it from the $600 left to pay.
$65*10 = $650
Now here is the hard part. We know that 600 < 650. So we need to subtract 650 from 600.
$650 - $600 = $50
Now we need to find how much more Mohamed paid than the original price.
$850 is _____% more than $800.
$850 is 106.25% more than $800.
Subtract 100% to get the difference.
6.25% is your answer.

Can someone help me with this ? Not really sure how to solve it, I'll give brainliest too !
Answer: y=5x+4
Step-by-step explanation:
Remember this
Slope-Intercept form: y=mx+b
m is the slope (5)
b is the y-intercept (4)
So your equation is
y=5x+4
Answer:
y = 5x + 4
Step-by-step explanation:
y - 4 = 5(x - 0)
That is point-slope form. I'm not sure if you want it in slope-intercept form, but the slope-intercept form of the equation is -
y = 5x + 4

The inequality that describes the possible value of x is 2< x < 22.
What is inequality?In mathematics, "inequality" refers to a relationship between two expressions or values that is not equal to each other. Therefore, inequality emerges from a lack of balance.
Given that ∠A = 50°
AB ≈ DE ≈ EF
BC = 12
CD = 10
And the ∠E = (5x - 10)°
From the Graph, we can see that Angle A is the alternate angle to angle G
Alternate angles are the angles that occur on opposite sides of the transversal line. We can easily spot two interior alternate angles by drawing Z. The value of alternate angles is equal.
thus, ∠A = ∠E
50° = 5x -10
5x = 60
x = 12
Therefore, from the given options the value of x lies in the inequality 2 < x < 22.

The doubling period of a bacterial population is 15 minutes. At time t= 80 minutes, the bacterial population was 90000
Answer:
here i finished!
hope it helps yw!
Step-by-step explanation:
The doubling period of a bacterial population is 15 minutes.
At time t = 90 minutes, the bacterial population was 50000.
Round your answers to at least 1 decimal place.
:
We can use the formula:
A = Ao*2^(t/d); where:
A = amt after t time
Ao = initial amt (t=0)
t = time period in question
d = doubling time of substance
In our problem
d = 15 min
t = 90 min
A = 50000
What was the initial population at time t = 0
Ao * 2^(90/15) = 50000
Ao * 2^6 = 50000
We know 2^6 = 64
64(Ao) = 50000
Ao = 50000/64
Ao = 781.25 is the initial population
:
Find the size of the bacterial population after 4 hours
Change 4 hr to 240 min
A = 781.25 * 2^(240/15
A = 781.25 * 2^16
A= 781.25 * 65536
A = 51,199,218.75 after 4 hrs
