1.2 * 10^-5 or 0.000012

Answer:

Step-by-step explanation:

Given equation is,

x² + (p + 1)x = 5 - 2p

x² + (p + 1)x - (5 - 2p) = 0

x² + (p + 1)x + (2p - 5) = 0

Properties for the roots of a quadratic equation,

1). Quadratic equation will have two real roots, discriminant will be greater than zero. [(b² - 4ac) > 0]

2). If the equation has exactly one root, discriminant will be zero [(b² - 4ac) = 0]

3). If equation has imaginary roots, discriminant will be less than zero [(b² - 4ac) < 0].

Discriminant of the given equation = [tex](p+1)^2-4(1)(2p-5)[/tex]

For real roots,

[tex](p+1)^2-4(1)(2p-5)>0[/tex]

p² + 2p + 1 - 8p + 20 > 0

p² - 6p + 21 > 0

For all real values of 'p', given equation will be greater than zero.

Answer:

To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points

Answer:

To the find slope in slope-intercept form (y=mx+b) you just find the m of the equation for example: y=4x+8 the 4 is the slope since it is replacing the m

To find the slope in two points (x1,y1) (x2,y2) follow this formula

y2-y1/x2-x1

For example: Find the slope of (4,9) and (9,19)

19-9/9-4 Which is 10/5 simplify: 2

The slope is 2

Answer:

they really brought the ps5 in a quiz lol

Step-by-step explanation:

Given:

The endpoints of line segment CD are C(-4,7) and D(0,-3).

To find:

The midpoint of CD.

Solution:

Midpoint formula:

[tex]Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]

Using the midpoint formula, the midpoint of CD is

[tex]Midpoint=\left(\dfrac{-4+0}{2},\dfrac{7-3}{2}\right)[/tex]

[tex]Midpoint=\left(\dfrac{-4}{2},\dfrac{4}{2}\right)[/tex]

[tex]Midpoint=\left(-2,2\right)[/tex]

Therefore, the midpoint of the line segment CD is (-2,2).

8. b1= 4, b2= 10, h= 5.2, A= 36.4

9. b1= 7, b2= 13, h= 4.2, A= 42

Answer:

m∠GFT = 142°

Step-by-step explanation:

∠GFT and ∠DFT are supplementary.

m∠GFT + m∠DFT = 180

7f + 163 + 6f + 56 = 180

13f + 219 = 180

13f = -39

f = -3

m∠GFT = 7f + 163 = 7(-3) + 163 = -21 + 163 = 142

Answer:

b. x=2

Step-by-step explanation:

The axis of symmetry of a parabola gives us a line of symmetry where the parabola appears the same but flipped on either side. It passes through the parabola's vertex, or the minimum/maximum point of the parabola. Here, we can see that the parabola's minimum point occurs when x=2. Therefore, its axis of symmetry is x=2.

Answer:

i think c just see what the other people say first to make sure

Step-by-step explanation:

answer is 170

---------------------------

50% of 850 = 425

30% of 850 = 255

425 + 255 = 680

850 - 680 = 170

There are 170 kg mass of parsnips left after distributing to the local market and local supermarket.

To calculate the mass of parsnips left after distributing them to the local market and the local supermarket, we need to subtract the quantities allocated to these places from the total harvest.

The farmer harvested 850 kg of parsnips.

30% of the harvest goes to the local market, which is (30/100) * 850 kg = 0.3 * 850 kg = 255 kg.

50% of the harvest goes to the local supermarket, which is (50/100) * 850 kg = 0.5 * 850 kg = 425 kg.

To find the mass of parsnips left, we subtract the quantities allocated to the market and supermarket from the total harvest:

Total harvest - (Quantity for market + Quantity for supermarket)

= 850 kg - (255 kg + 425 kg)

= 850 kg - 680 kg

= 170 kg.

Therefore, there are 170 kg of parsnips left after distributing to the local market and local supermarket.

Answer:

D) -3(2m -1) -n = -6m-n + 3

Step-by-step explanation:

4.5÷4= 1.125

so each time she goes around the rectangle she's covering 1.125 km and we seed the length is twice the breadth x+2x=1.125

so 1.125 / 3 to give x which is the breadth=0.375 x 2 is equal to 0.75 km or 750 m this is the length of the field

Step-by-step explanation:

The length of a rectangular field is twice it's breadth. A girl jogged around it 4 times and covered a distance of 4.5 km. What is the length of the field?

The distance cover in 4 laps is 4.5 km, So one lap is 4.5/4 = 1.125 km.

Let the breadth of the field be B so the length will be L or 2B.

The perimeter of the field is 2L+2B or 4B+2B = 6B = 1.125, so B = 1.125/6 = 0.1875 km and the length is 2*0.1875 = 0.375 km.

Check: perimeter = 2*0.375 + 2*0.1875 = 1.125 km and 4 laps covers 4*1.125 = 4.5 km. correct.

The field is 375 m long.

Answer:

3/4 is less than 7.

Step-by-step explanation:

There are 4 numbers but there are only 3 less than 7.

The probability P(less than 7) is 3/4.

Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.

For the given situation,

The cards are numbered as s = {4,5,6,7}

⇒[tex]n(s)=4[/tex]

The event is probability of picking the cards less than 7

Cards less than [tex]7[/tex] ,  [tex]e=4,5,6[/tex]

⇒[tex]n(e)=3[/tex]

Probability of picking the card is given by [tex]p(e)=\frac{n(e)}{n(s)}[/tex]

On substituting the values,

⇒[tex]p(less than 7)=\frac{3}{4}[/tex]

Thus the probability P(less than 7)  is 3/4.

Step-by-step explanation:

To find the area of a triangle, you must use the formula A=1/2xbxh.

For this triangle, the base is 13 and the height is 4. So, multiply the 13 by 4 to get a total of 52, and then divide by 2 to get your final answer of 26.

Answer:

$7

Step-by-step explanation:

if she bought 10 bags and had $5 off and she spent $65 it would technically its $70 ÷ 10 = $7 per bag.

Each bag of dog food cost $7.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

We have,

Molly bought 10 bags of the same dog food.

She had a coupon for $5.

and, the amount without coupon is $65.

Then, the total amount is

= 65 + 5

= $70

So, the price per bag is

= 70/ 10

= $7

Answer:

Step-by-step explanation:

To find the slope, you need to find the y-intercept first (or the place the line crosses over the y-line). After you've found the y-intercept (-1), you need to find the next point that the line crosses. This line has a positive slope, so you'll want to look for the next point towards the right. The next point was 1 up and 2 over.

Answer:

y = 2/5x - 1

Step-by-step explanation:

There are a couple of different ways to figure this out, but since you have a graph, the fastest way is to count the slope, or m in the formula, by counting the rise (units up) over run (units to the right), which is 2/5. Then, find the value of b by finding the y-intercept on the graph, or -1.
