please help me!!!!! i need help with this, very urgent! ASAP

Work Shown:

p-q = -7

(p-q)^2 = (-7)^2

p^2-2pq+q^2 = 49

p^2-2(-10)+q^2 = 49

p^2+20+q^2 = 49

p^2+q^2 = 49-20

p^2+q^2 = 29

By the difference of cubes formula, we can say,

p^3 - q^3 = (p-q)*(p^2+pq+q^2)

p^3 - q^3 = (p-q)*(p^2+q^2+pq)

p^3 - q^3 = (-7)*(29-10)

p^3 - q^3 = -133

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

Here's another way to solve:

p-q = -7

p = q-7

pq = -10

(q-7)*q = -10

q^2-7q = -10

q^2-7q+10 = 0

(q-5)(q-2) = 0

q-5 = 0 or q-2 = 0

q = 5 or q = 2

If q = 5, then p = q-7 = 5-7 = -2

If q = 2, then p = q-7 = 2-7 = -5

We can see that no matter what we pick for q, we'll get p*q = -10

Also, you should find that p^3-q^3 is equal to -133 for either case as well.

Step-by-step explanation:

Given

Box of a box plot with the range: 60 - 64

Required

The upper quartile

To do this, we simply identify the endpoint of the range

Given that the range of the box is 60 to 64.

We have:

[tex]Start = 60[/tex]

[tex]End = 64[/tex]

Hence:

[tex]Q_3 = 64[/tex]

Answer:

$519

Step-by-step explanation:

Given the amount of profit made expressed as y=-2x^2+105x-859

At maximum profit, dy/dx = 0

dy/dx = -4x + 105

0 = -4x + 105

4x = 105

x = 105/4

x = 26.25

Substitute into the original function

y=-2x^2+105x-859

y=-2(26.25)^2+105(26.25)-859

y = - 1,378.125+2,756.25-859

y = 519.125

Hence the maximum amount of profit the company can make is $519

Answer:

Options A and E

Step-by-step explanation:

Isosceles triangle → Two sides and opposite angles of the equal sides will be equal

In the given triangle measure of all sides are different.

Therefore, it's not an isosceles triangle.

Equilateral triangle → All sides and opposite angles are equal.

Given triangle is not an equilateral triangle.

Scalene triangle → All sides and angles are different in measure.

It's an scalene triangle.

Since, one angle of the triangle is a right triangle, it's a right triangle.

Option A and E are the correct options.

Line AB || Line CD {sun height are parallel}

Angle ACB parallel to Angle DEC = 90°

Triangle ABC is parallel to Triangle DCE

12/61 * 2.5

=4.5 feet

Answer:

x = 4

Step-by-step explanation:

The line in the triangle is an angle bisector and divides the opposite sides into segments that are proportional to the other 2 sides, that is

[tex]\frac{x+6}{20}[/tex] = [tex]\frac{x}{8}[/tex] ( cross- multiply )

20x = 8(x + 6) = 8x + 48 ( subtract 8x from both sides )

12x = 48 ( divide both sides by 12 )

x = 4

Area of a rectangle = length x width

assume width = 10

older area = 44 x 10 = 440

new area

length = 44 x 2 = 88

88 x 10 = 880

change in area = 880 / 440 = 2

=======================================================

Explanation:

We use the cosine ratio here. Make sure your calculator is in degree mode.

cos(angle) = adjacent/hypotenuse

cos(69) = x/10

10*cos(69) = x

x = 10*cos(69)

x = 3.583679495453 which is approximate

x = 3.6

Answer:

20 apples, 32 pears

Step-by-step explanation:

Using a for number of apples and p for number of pears, you get a+p=52 (amount) and 0.4a+0.5p=24 (cost).

One way of solving simultaneous equations is using like terms and adding/subtracting them to remove a variable. There aren't any like terms here, but we can create some by multiplying terms.

Multiplying the second equation by 2 gives 0.8a+p=48, so that makes a like term.

Since the symbols are the same in front of the like term, we subtract the second term from the first one. This gives 0.2a=4.

Dividing by 0.2 gives a=20.

We can sub this into either equation to get the value of p.

a+p=52, so 20+p=52, meaning p=32.

Answer:

$14.7

Step-by-step explanation:

Zeke owns stock in a high tech firm

Each share is valued at $21

It's is 30% less than the amount it was purchased

Therefore Zeke pay per share can be calculated as follows

= 21× 30/100

= 21×0.3

= 6.3

= 21-6.3

= 14.7

Hence Zeke's pay per share is $14.7

Answer:

✓✓ Area of traingle = 1.2 cm^2 ✓✓

Step-by-step explanation:

Hello mate (◕ᴗ◕✿)

=>> In above traingle, height and hypotenuse are given

=> height = 12 cm

=> Hypotenuse = 14 cm

✓✓ Area of traingle = 1/2(base*height) ✓✓

we need to find base of above traingle

Base = √Hypotenus - √Perpindicular

Base = √14 - √12

Base = 3.7 - 3.4

Base = 0.2 cm

Now, we can find area of traingle

Area of traingle = 1/2(Base*Height)

Area of traingle = 1/2(0.2*12)

Area of traingle = 6*0.2

Area of traingle = 1.2 cm^2

Hope it helps you mate (. ❛ ᴗ ❛.)

Answer :

➢ 43.3 cm²

Explanation :

let the missing side be c

a = 12 cm

b = 14 cm

Pythagoras theorem :

➢ a² + c² = b²

➢ 12² + c² = 14²

➢ 144 + c² = 196

➢ c² = 196 - 144

➢ c² = 52

➢ c = √52

➢ c = 7.21

Area = 1/2 × a × c

➢ 1/2 × 12 × 7.21

➢ 6 × 7.21

➢ 43.26 cm²

➢ 43.3 cm² [ round off to 1 decimal place ]

Answer:

Step-by-step explanation:

Given that :

Total Number of scorings (both Teams) = 18

Let :

x = number of 5 point score ; y = number of 2 point score

Total points scored = 34 + 29 = 63

x + y = 18 - - - (1)

5x + 2y = 63 - - (2)

From (1)

y = 18 - x

In (2) ; we have ;

5x + 2(18 - x) = 63

5x + 36 - 2x = 63

3x + 36 = 63

3x = 63 - 36

3x = 27

x = 9

Answer:

Step-by-step explanation:

The distance between the vertex and the directrix is 4 units, that means that p = 4 in the equation

[tex](y-k)^2=4p(x-h)[/tex] and h and k are the coordinates of the vertex. Filling in:

[tex](y+4)^2=4(4)(x+2)[/tex] which simplifies to

[tex](y+4)^2=16(x+2)[/tex] choice C

Option C is correct, (y+4)² = 16(x+2) is the the equation of the parabola, in vertex form, with vertex at (-2,-4) and directrix x = -6

A parabola is a plane curve which is mirror-symmetrical and is approximately U-shaped.

The focus of the parabola is at a point that is equidistant to the vertex and the directrix.

Since the directrix is x = -6, the focus is at (-2+4,-4) = (2,-4).

The vertex form of the equation of a parabola is given by:

(y - k)² = 4p(x - h)

where (h, k) is the vertex and p is the distance between the vertex and focus.

In this case, (h, k) = (-2,-4) and the focus is at (2,-4). Therefore, p = 4.

Substituting the values into the vertex form equation, we get:

(y + 4)² = 4(4)(x + 2)

Simplifying, we get:

(y + 4)² = 16(x + 2)

Hence, (y+4)² = 16(x+2) is the the equation of the parabola, in vertex form, with vertex at (-2,-4) and directrix x = -6

Step-by-step explanation:

Smoking damages your entire cardiovascular system. Speaking of this Nicotine causes blood vessels to tighten, which restricts the flow of blood. Over time, the ongoing narrowing, along with damage to the blood vessels, can cause *peripheral artery disease*. Smoking also raises blood pressure, weakens blood vessel walls, and increases blood clots.

* Peripheral artery disease is a common circulatory problem in which narrowed arteries reduce blood flow to your limbs
