Answer:

s = -1

Step-by-step explanation:

7 = -10s -3 <== add 3 to both sides

+3        + 3

10 = -10s <== divide both sides by -10

/-10    /-10

-1 = s

Final answer: -1 = s  or  s = -1

If the area of the square is 36 square units. Then the area of the circle will be 28.26 square units.

It deals with the size of geometry, region, and density of the different forms both 2D and 3D.

The area of the square will be given as 36 square units.

Then the side length of the square will be

36 = a²

 a = 6 units

Then the diameter of the circle and side length of the square are equal. Then we have

a = d = 6 units

Then the radius of the circle will be

2r = d

2r = 6

 r = 3 units

Then the area of the circle will be

Area of circle = πr²

Area of circle = 3.14 x 3²

Area of circle = 28.26 square units.

Answer:

8

Step-by-step explanation:

To calculate the greatest common factor of 24 and 32, we need to factor each number (factors of 24 = 1, 2, 3, 4, 6, 8, 12, 24; factors of 32 = 1, 2, 4, 8, 16, 32) and choose the greatest factor that exactly divides both 24 and 32, i.e., 8.

Answer:

8

(factors of 24 = 1, 2, 3, 4, 6, 8, 12, 24; factors of 32 = 1, 2, 4, 8, 16, 32)

Answer:

32

Step-by-step explanation:

7×18+2×18=32

x=14

y=18

Have a great day!

Explanation:

The jump from 24 to 16 is -8

The jump from 16 to 8 is also -8

Each time we need a new term, we add on -8 which is the common difference. So we'll add -8 to 0 to get 0 + (-8) = 0 - 8 = -8 as the next term.

If you wanted another term after that, then it would be -8 + (-8) = -8-8 = -16

Then the next term after that is -16+(-8) = -16-8 = -24, and so on.

Answer:

-8

Step-by-step explanation:

each time its going down by 8 meaning it would be -8

Answer:

d.  (4w2 + 180w) m2

Step-by-step explanation:

Area of tiled floor = (area of tiled floor+ pool ) - area of pool

area of pool =l x b = 30 x 60 =1800  ...............a

length of pool + tiled floor = 30+2w

breadth of pool + tiled floor = 60+2w

Hence, (area of tiled floor+ pool ) =

(30+2w) x(60+2w) = 1800+60w+120w+4w2 = 1800 + 180w+4w2.....b

b-a =(1800+ 180w+4w2)- 1800 = 4w2 + 180w

The total he would have to pay back would be $7,320.44

Step-by-step explanation:

(I'm assuming you want the total amount he needs to pay back)

6700 x 0.10 = 670 per year

670 ÷ 365 = 1.835616438356164

1.835616438356164 × 338 = 620.44

620.44 + 6700 = 7,320.44

The missing probability for the given mutually exclusive event is 3/10

Mutually exclusive events are those events that do not occur at the same time.

Here, Let P(A) be x,

         P(B) = 11/20,     P(A or B) = 17/20,    P(A and B) = 0

         By Addition theorem of Probability,

         P(A or B) = P(A) + P(B) - P(A and B)

          17/20 = x + 11/20 - 0

          x = [tex]\frac{17}{20} - \frac{11}{20}[/tex]

          x = 6/20

          x = 3/10

Thus, The missing probability for the given mutually exclusive event is 3/10

Answer:

C) 3/10

Step-by-step explanation:

Applying the Addition Theorem of Probability :

P(A ∪ B) = P(A) + P(B) - P(A ∩ B)

Here :

Solving :

The relationship between angle A and angle B is supplementary angles.

∠A  = 2(5) + 40 = 50 degrees

∠B = 5 + 125 = 130 degrees

Supplementary angles are angles that sum up to 180 degrees. The sum of the two angles for a supplementary angles is 180 degrees .

Therefore, the relationship between angle A and angle B is supplementary angles.

Therefore,

∠A + ∠B = 180 degrees

∠A  = 2x + 40

∠B = x + 125

2x + 40 +  x + 125  = 180

2x + x + 40 + 125 = 180

3x + 165 = 180

3x = 180 - 165

3x = 15

x = 15 / 3

x = 5

Therefore,

∠A  = 2(5) + 40 = 50 degrees

∠B = 5 + 125 = 130 degrees

Step-by-step explanation:

what is the problem ?

we only need to use the formula that can be found easily on the internet.

the area of a circle is

pi×r²

r being the radius (half of the diameter). in our case :

14/2 = 7 m

and we shall use 22/7 as approximation for pi.

so, we get as circle area

22/7 × 7² = 22 × 7 = 154 m²

Answer:

y - 3 = -2 * (x+2)

Step-by-step explanation:

Answer:

y-6.7=0* (x+3)

Step-by-step explanation:

Answer:

See below for answers and explanations

Step-by-step explanation:

Problem 1

Let [tex]z=r(\cos\theta+i\sin\theta)[/tex] be a complex number, where [tex]n[/tex] is an integer and [tex]n\geq 1[/tex]. By DeMoivre's Theorem, if [tex]z^n=r^n(\cos\theta+i\sin\theta)^n[/tex], then [tex]z^n=r^n(\cos n\theta+i\sin n\theta)[/tex].

Hence, we must first convert from rectangular to polar form:

[tex]z=-1-i\\\\r=\sqrt{a^2+b^2}\\\\r=\sqrt{(-1)^2+(-1)^2}\\\\r=\sqrt{1+1}\\\\r=\sqrt{2}[/tex]

[tex]\displaystyle \theta=\tan^{-1}\biggr(\frac{y}{x}\biggr)\\\\\theta=\tan^{-1}\biggr(\frac{-1}{-1}\biggr)\\ \\\theta=\tan^{-1}(1)\\\\\theta=45^\circ[/tex]

Therefore, the rectangular form for the complex number is [tex]z=\sqrt{2}(\cos45^\circ+i\sin45^\circ)[/tex], and now we can apply DeMoivre's Theorem to raise the complex number to the 10th power:

[tex]z=\sqrt{2}(\cos45^\circ+i\sin45^\circ)\\\\z^{10}=\sqrt{2}^{10}(\cos45^\circ+i\sin45^\circ)^{10}\\\\z^{10}=2^5(\cos10\cdot45^\circ+i\sin10\cdot45^\circ)\\\\z^{10}=32(\cos450^\circ+i\sin450^\circ)\\\\z^{10}=32(0+i)\\\\z^{10}=32i[/tex]

Therefore, [tex]z^{10}=32i[/tex] in rectangular form.

Problem 2

[tex]3\:\text{cis}\:90^\circ=3(\cos90^\circ+i\sin90^\circ)=3(0+i)=3i[/tex]

Therefore, [tex]3\:\text{cis}\:90^\circ=3i[/tex] in rectangular form.
