Answer:
Option 'D' is correct.
Step-by-step explanation:
Since we have given that
Both the first and second signs are negative,
Let α and β are the roots of the ,
then, we know that the relationship between the zeroes and coefficients of quadratic equations:
Since the product of roots is positive.
So, the signs of the factors will be one positive and one negative.
Hence, Option 'D' is correct.

Step-by-step explanation:
Cait can bike 32 miles in the same amount of time that Carl can bike 24 miles. If Cait bikes 2 mph faster than Carl, how fast does Cait bike?
Let t = time in hrs for both to go 32 mi
Let s = Carl's speed in mi/hr
s + 2 = Caits speed in mi/hr
------------------------------------------------------------
Carl's equation:
(1) 24 = s · t
Cait's equation:
(2) 32 = (s+2) · t
-----------------------------------
(2) 32 = s · t + 2t
and
(1) s = 24/t
Plug (1) into (2)
(2) 32 = (24/t) · t + 2t
(2) 32 = 24 + 2t
(2) 2t = 8
(2) t = 4
and
(1) s = 24/4
(1) s = 6
The speed of Cait is 8 mph
What is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them. Variables are the name given to these symbols because they lack set values. We frequently observe constant change in specific variables in our day-to-day situations. But the need to depict these shifting values is ongoing. These values are frequently represented in algebra by symbols such as x, y, z, p, or q, and these symbols are known as variables. In order to determine the values, these symbols are also subjected to different addition, subtraction, multiplication, and division arithmetic operations.
Let x be the time in hours for both to go 32 miles
Let y be Carl's speed
Then Caits speed is = y+ 2
So, Carl's equation:
x y= 24
and, Cait's equation:
32 = (y+2) · x
32 = xy + 2x...............(1)
and, y = 24/x
Put the above value in equation (1)
(24/x) x + 2x = 32
2x+ 24 = 32
2x= 8
x=4
Also, y= 24/x= 24/4 = 6
Hence, speed of Cait is 8 mph

Last month, Ben rode his bike 24 miles a week for 4 weeks. This month, Ben ride his bike 28 miles a week for 3 weeks. How many miles did Ben ride his bike in all?
Answer:
180
Step-by-step explanation:
Multiply 24x4=96
Then, multiply 28X3=84
Finally add the 2 for a total of 180
Answer:
180 miles
Step-by-step explanation:
Basically, if he rode his bike 24 miles each week and he rode it for 4 weeks you would multiply 24 times 4, which gives you 96 miles. Then, you would do the same for the 28, 28 times 3 gives you 89 miles. Lastly, you add it all up. 96+89= 180 miles

Maria import special clay pots from Brazil. A shipment of 50 pots cost her $350. She then sells the pots at local fairs and art shows. On her last shipment she made a profit of $750. (1) What is the cost of 1 clay pot? (2) what is the total amount of sell in order to make the profit? (3) How much does she need to sell each pot in order to make the profit?
Answer:
Q 1) 7$ Q 2) 50 Q 3) 15$
Step-by-step explanation:
1) The cost of 1 claypot = $7
2) Total amount sold to yield the given profit = $1100
3) Amount to sell each pot to make the given profit = $22
We are given that;
Cost of 50 pots = $350
1) Since 50 pots costs $350, the cost of one pot will be;Cost of 1 clay pot = 350/50 = $7 per clay pot
2) She made a profit of $750 on the 50 pots.This means amount she sold in order to make the profit will be;
$350 + $750 = $1,100
3) Since total amount she sold to make the profit is $1,100, then amount each pot was sold to yield that profit on the 50 clay pots will be;1100/50 = $22 per pot

The relation you're supposed to apply here is ...
an exterior angle of a triangle is equal to the sum of the remote interior angles.

The exterior angle is 17x+7, and it is equal to the sum of the two marked angles inside the triangle.
17x +7 = 13x +3 +40
4x = 36 . . . . . . . . . . . . . subtract 13x+7 from both sides

What is the problem for this Problem?
Answer:
Negative: (-∞,-3] and [1/2,-∞)
Positive: [-3,1/2]
Step-by-step explanation:
The derivative is the instantaneous rate of change at any given point for a function. Given this we know that anywhere the function is in the positive or negative direction, the derivative will also be in the positive or negative direction. We also know that wherever there is a peak or a trough, there will be no slope and it signifies a change in direction. For this function, this means the direction changes at -3 and 1/2.
Kylie is buying a new pair of tennis shoes. The price tag says that the shoes are
regularly priced at $68.80. Kylie has a coupon for 20% off.
Part A: How much money will Kylie save if she uses the coupon? Show your
work.
Part B: How much will Kylie pay for the shoes after the discount? Show your
work.
Answer:
Part A: $13.76 saved. Part B: $55.04
Step-by-step explanation:
Part A: Set a proportion up d/68.8 = 20/100
100·d=100d 68.8·20=1376
100d/100 cancels out
1376/100=13.76 so $13.76 was saved
Part B: 68.80-13.76= 55.04 so $55.04 was what he paid.

Did you know that an unopened 355 mL can of diet Dr. Pepper will float in a lake? That's a fact! However, it's also a fact that an unopened 355mL can of regular Dr. Pepper will sink in that same lake! Based on these two facts, which type of soda is the least dense? Explain your answer.
Answer: An unopened can of Diet Dr. Pepper is the least dense.
Step-by-step explanation:
For a solid object to float in a liquid, it must be less dense.
Let's associate the density of Diet Dr. Pepper with x, Dr. Pepper with y, and lake water with z.
Because of the above fact, x < z, and y > z. Thus, x < z < y, and x < y.

Find the values of p and q given that x⁴ + x³ - 7x² + px + q is divisible by (x - 1) and (x + 2)
Answer:
p = - 5, q = 10
Step-by-step explanation:
If f(x) is divisible by (x - h) then f(h) = 0
Here
f(x) = [tex]x^{4}[/tex] + x³ - 7x² + px + q
dividing by (x - 1) with h = 1 , then
[tex]1^{4}[/tex] + 1³ - 7(1)² + p + q = 0, that is
1 + 1 - 7 + p + q = 0
- 5 + p + q = 0 ( add 5 to both sides )
p + q = 5 → (1)
Dividing by (x + 2) with h = - 2 , then
[tex](-2)^{4}[/tex] + (- 2)³ - 7(- 2)² - 2p + q = 0 , that is
16 - 8 --- 28 - 2p + q = 0
- 20 - 2p + q = 0 ( add 20 to both sides )
- 2p + q = 20 → (2)
Subtract (1) from (2) term by term, thus eliminating q
- 3p = 15 ( divide both sides by - 3 )
p = - 5
Substitute p = - 5 into (1) and solve for q
- 5 + q = 5 ( add 5 to both sides )
q = 10
