What polynomial must be added to z2 + 4z – 7 in order for the sum of the two polynomials to be 2z2 + z + 7 ?

Answer:

(x-3)^2 = 3

Step-by-step explanation:

V = π r² h

r = 3/2 = 1.5m

h = 3m

taking π as 3.14

V = π r² h

= 3.14 × 1.5 ×1.5 × 3

= 21.195 m³

Answer:

B. Clockwise 270-degree rotation

Answer:

B) Clockwise 270-degree rotation

Step-by-step explanation:

Clockwise motion is in the same direction as a clock's hands: from the top to the right, then down and then to the left, and back up to the top. The opposite motion is counterclockwise.

From inspection of the diagram, we can see that the curved dotted line (which shows the direction of motion) is suggesting a clockwise motion.

Answer:

17/4

Step-by-step explanation:

Solution:

Your problem → 2((1/8)+ 4) - ((3/6)*8)

2((18)+4)-((36)⋅8)

=2⋅(1/8)+4-((36)⋅8)

=2⋅(1+4×8)/8-((36)⋅8)

=2⋅(1+32)/8-((36)⋅8)

=2⋅(33/8)-((36)⋅8)

=2⋅(33/8)-((36)⋅8)

=(33/4)-((36)⋅8)

=(33/4)-(36⋅8)

=(33/4)-(12⋅8)

=(33/4)-12⋅8

=(33/4)-4

=(33/4)-4

=(33-4×4)/4

=(33-16)/4

=17/4

Given that the two pentagons are similar figures, the area of the pool = 675 sq. m..

If two figures are similar to each other, then, the ratio of the square of their corresponding sides equals the ratio of their areas.

We are given that the pool and the park are similar to each other. The diagram given is missing, however, here's how to find the area of the pool:

If x is a side of the pool and y is the corresponding side length of the park, therefore:

area of pool/area of park = x²/y².

Plug in the values given, cross multiply and find the area of the pool.

For example, if 3 is a side of the pool = x

6 is corresponding side of the park = y

Area of park = 2,700 sq. m

Thus:

Area of pool/2,700 = 3²/6²

Area of pool/2,700 = 9/36

Area of pool = (9 × 2,700)/36

Area of pool = 675 sq. m.

There are 64 chickens

Step-by-step explanation:

60% of the animals were not chickens so I found 60% of 160 which is 96, and then I subtracted 96 from 160 and got 64

Please mark brainlest for my overcomplicated description of math

Answer:

16 horses

32 cows

48 goats

64 chickens

Step-by-step explanation:

total animals = 160

⇒ 10% of animals = 160/10 = 16

⇒ 20% = 16 x 2 = 32

⇒ 30% = 16 x 3 = 48

16 horses

32 cows

48 goats

chickens = 160 - 16 - 32 - 48 = 64

The average speed of the car for the entire journey is 60 miles per hour.

The average speed is the total distance traveled by the object in a particular time interval.

Given

It takes a car 1. 75 hours to go from mile marker 10 to mile marker 115.

The average speed of the car is given by;

[tex]\rm Average \ speed =\dfrac{Average \ Distance}{Time}\\\\ \rm Average \ speed =\dfrac{115-10}{1.75}\\\\\rm Average \ speed =\dfrac{105}{1.75}\\\\\rm Average \ speed = 60 \ mph[/tex]

Answer:

The lattes would cost about 22.50

Step-by-step explanation:

In order to figure out how much 6 lattes cost we need to know how much 1 is.

So you take 15 divided by 4 which gets you 3.75

Then you take 3.75 and times it by 6. Getting you the answer of 22.50

Answer:

$22.5

Step-by-step explanation:

It would be 22.5$ because if lattes cost 15$ then we need to find the cost of 1.

To do this by we divide 15 by 4.

     3.75

4{15}

 -0

___

  15

- 12

--------

    3 so because there is 3 left of 4 is is .75 because it couldn't make it to 4

so since 1 latte cost 3.75$ we times 3.75 by 6 latte.

Here are 3.75 times numbers 1-6.

3.75 x 3=11.25

3.75 x 4=15

3.75 x 5=18.75

3.75 x 6=22.5 and there's your answer,you get 6 lattes for 22.5$ or 22$ and 50 cents.

Surface area of square pyramid is given by the sum of areas of all its 4 triangular sides and the square base area. If a is the base side length and l is the slant height , then the surface area of square pyramid is:

‎ㅤ‎‎ㅤ‎ㅤ‎ㅤ‎ㅤ➙ a² + 2al

Ⲧⲏⲉⲅⲉ⳨ⲟⲅⲉ:

‎ㅤ‎ㅤ‎ㅤ➙ A = a² + 2al

‎ㅤ‎ㅤ‎ㅤ➙ A = ( 3 ) ² + 2 × 3 × 5

‎ㅤ‎ㅤ‎ㅤ➙ A = 9 + 30

‎ㅤ‎ㅤ‎ㅤ➙ A = 39m²

~Hence, the surface area of given square pyramid is 39 m².

Answer:

39 m²

Step-by-step explanation:

surface area of square based pyramid = [tex]a^2+2al[/tex]

(where [tex]a[/tex] is the side length of the base and [tex]l[/tex] is the slant height)

Given:

⇒ SA = 3² + (2 x 3 x 5) = 39 m²        

Answer:

Well technically its inf due to the arrow, there  are no points showing where to start from and where to end

the way you do it it you just count the amount of units it goes up, in this case for every square its going up 5 units, once you get that number you put that on top of your fraction, then you go over on the x axis till you hit your line (x axis is going by 10 every time). This would be your number on the bottom of the fraction.

Answer:

[tex]\left(-34, \dfrac{33}{2}\right)[/tex]

Step-by-step explanation:

Create a linear equation for line AB and line CD

Find slope using slope formula [tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

then use point-slope form of linear equation [tex]y-y_1=m(x-x_1)[/tex]

(where m is the slope and [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] are two points on the line)

Line AB

[tex]m=\dfrac{-16+1}{-8+20}=-\dfrac54[/tex]

[tex]\implies y+1=-\dfrac54(x+20)\\\\\implies y=-\dfrac54x-26[/tex]

Line CD

[tex]m=\dfrac{0+11}{-19+9}=-\dfrac{11}{10}[/tex]

[tex]\implies y+11=-\dfrac{11}{10}(x+9)\\\\\implies y=-\dfrac{11}{10}x-\dfrac{209}{10}[/tex]

To find the point of intersection, equate the equations and solve for x::

AB = CD

[tex]\implies -\dfrac54x-26=-\dfrac{11}{10}x-\dfrac{209}{10}[/tex]

[tex]\implies -\dfrac{3}{20}x=\dfrac{51}{10}[/tex]

[tex]\implies x=-34[/tex]

Substitute found value of x into one of the equations and solve for y:

[tex]y=-\dfrac54(-34)-26=\dfrac{33}{2}[/tex]

Therefore, point of intersection is  [tex]\left(-34, \dfrac{33}{2}\right)[/tex]

D) she used a compass at P with a radius set equal to 3/4(PQ)

Step-by-step explanation:

Step 1

She used a compass at P with a radius set equal to 3/4PQ .

Step 2

Since if ∆MNP is equilateral triangle so, PM=PN=MN

Since O is center then PO=OQ

And let R is the mid point of MN.

So, R is also mid point of OQ.

Hence, she used a compass at P with a radius set equal to 3/4(PQ)
