I need help on this since we don’t got a teacher we never learned about this

Answer:

The y intercept is -8, or (0, -8)

Step-by-step explanation:

p(x)=-3(x-2)²+4

p(x)=-3(x²-4x+4)+4

p(x)=-3x²+12x-12+4

p(x)=-3x²+12x-8

This is quadratic

In p(x)=ax²+bx+c

c is the y intercept

Therefore the y intercept is -8, or (0, -8)

Hope this helps! :D

<3

Answer:

(0,-8)

Step-by-step explanation:

The y intercept occurs when x = 0 , so put in x = 0

-3(0-2)^2 + 4   = -8  

so y-axis intercept is   ( 0, -8 )

Answer:

12.56 in²

Step-by-step explanation:

Area = πr²

Substitute for pi.

A = 3.14 × r²

The diameter is 4. We divide the diameter by 2 to get the radius.

4 ÷ 2 = 2

Substitute for the radius.

A = 3.14 × 2²

Solve

A = 3.14 × 4 = 12.56 in²

Answer:

4). 3

5). 600

Step-by-step explanation:

formula of finding intrest earned is (p×r×t)/100

by putting this formulae____

( HERE p means principal , r means rate , t means time )

(p×r×t) /100= interest

(480×r×5) / 100=100.80

(336×r) / 100 = 100.80

336×r= 100.80×100

r= (100.80×100)/336

r=3

5). (p×r×t)/100=interest

(p×4×5) /100 = 120.00

p×4×5 = 120.00×100

p= 12000 / 4×5

P=12000/20

P=600

Answer: 1.

Step-by-step explanation:

3yd is the diameter of this circle so

3yd × pi= 9.42yd

Answer:

125˚

Step-by-step explanation:

The angles given are supplementary. So we can set up the equation :

(3x+5)+(x+15)=180

Then we can solve for x.

Combine like terms:

4x+20=180

4x+20-20=180-20

4x=160

4x/4=160/4

x=40

Now we plug in 40 for x.

3(40)+5=<A

120+5=<A

<A=125

Answer:

No, it is not.

Step-by-step explanation:

The line of best fit is a line that runs across a scatter plot of data points and best reflects the connection between them. It must pass through the points on the graph for it to be the line of best fit.

Answer:

Tbh I am not sure but it's a semi-circle prism or like semi cylinder (I think) but usually semi-circles themselves will not tessellate bc circles have no angles and when u line them up next to each other there will be gaps between them and one of the tessellation rules is that no overlapping or gaps so yeah

I am sorry lol if that's all wrong but my answer is no, I don't think that this figure is a tessellate plane

Step-by-step explanation:

1) to calculate the measurement of Unlabeled angle:

180-90-27=63°;

2) to calculate the measurement of y:

180-51-63=66°

Answer:

y= 66
the angle that the arrow is pointing to = 63

Step-by-step explanation:

you can subtract 90 by 27 to get the angle measure that the arrow is 63

we know that all of the angles in a triangle are 180
so we can add up 51 and 63 to get 114
we subtract 180 by 114 to get 66
66 degrees

Answer:

pt for the triangles then 2(5x7) and 1(7x6) add it all together

Answer:

B

Step-by-step explanation:

Since there is 10 lines separating -3 and -4, that means the space between 2 lines in 1 tenth, and b is 3.5 lines away from -3. Making it -3.35

have a nice day :)

Answer:

B

Step-by-step explanation:

Each section represents 0.1

You would count 3 sections to the left of -3 because -3.35 is less than -3. You would end up at -3.3. Move to the left half a section for 0.05 and you would end up at point B, which is equal to -3.35.

Answer:

√169 & 13

Step-by-step explanation:

the area of a square is = to one side squared

Because of this, the side should equal the square root of the area.

13 is the square root of 169, and the square root of the area, 169, are both options, and fulfill the area formula for squares

Answer:

3.14 is the brainliest answer of them all

Answer:

3.14 sq cm

Answer:

Now, △DEF has interior angles with measures y°, 70°, and 20°.

By using angle sum property,

Now, we can say that,

"The two triangles are not similar because x≠y"

As one angle of measure 70 degree is common in both the triangles.

If 'x' would be equal to 'y' , then we could say that the triangles are similar by AA criteria.

Therefore, the two triangles are not similar because x is not equal to

Step-by-step explanation:

Answer:

the triangles are not similar. If they were, they would have the same angles.

The interior angles are not congruent. We can rule out choice B and C.

Just because they have one equal angle does not make them similar. We can rule out D.

A is the best answer.

Answer:

  8.5 ft

Step-by-step explanation:

We assume that Mr. Simpson can model his construction using a right triangle with leg 7 ft and hypotenuse 11 ft, as shown in the attachment. Then the other leg can be found using the Pythagorean theorem.

__

  a² +b² = c²

  x² +7² = 11²

  x² = 121 -49 = 72

  x = √72 = 6√2 ≈ 8.485 . . . . feet

The slide will be set about 8.5 feet away from the base.

Answer:

Volume = length x width x height.

You only need to know one side to figure out the volume of a cube.

The units of measure for volume are cubic units.

Volume is in three dimensions.

You can multiply the sides in any order.

Which side you call length, width, or height doesn't matter.

Answer:

5x - 1

Find Factors:

Factors: (2x-3)(3x+2)

Their sum:

Factor the trinomial 6x²-5x-6, then find the sum of the factors .

This question belongs to factorising the trinomial with the help of different methods such as middle term splitting .

[tex] \longrightarrow \: 6x {}^{2} - 5x - 6[/tex]

Now , by splitting the middle term that is - 5 x :

[tex] \longrightarrow \: 6x {}^{2} - 9x + 4x - 6[/tex]

Now , taking 3x and -2 as common :

[tex] \longrightarrow \: 3x(2x - 3) + 2(2x - 3)[/tex]

So ,

[tex] \longrightarrow \: ( 3x + 2 ) ( 2x - 3 )[/tex]

Therefore , factors are ,

In the question we have ask to find the sum of their factors . So adding them ,

Therefore , 5x - 1 is the sum of the factors .

Answer:

(5x-2)(5x+2)

Step-by-step explanation:

Rewrite 25x2 25 x 2 as (5x)2 ( 5 x ) 2 .

Rewrite 4 as 22 .

Since both terms are perfect squares, factor using the difference of squares formula, a2−b2=(a+b)(a−b) a 2 - b 2 = ( a + b ) ( a - b ) where a=5x a = 5 x and b=2 .

Answer:

The Area is: 84ft

Step-by-step explanation:

multiply "Y" and "X" and you get 78ft.

"W" + "?"= "Y" If "W"=7, what is 13 ("Y") - 7? 13 -7=6. so "?"=6.

"Z"-"X"="?" "Z"=8 and "X"=6. so 8-6=2

2x6=12 *but remember that to find the area of a triangle it is half of a square of rectangle so you have to divide it in half. 12/2=6.

78+6=84.

Hope this helps! :)

Answer:

x = 44.3

Step-by-step explanation:

Knowing that the given figure shows a supplementary angle

⇒ Note that: Supplementary angle= 180 °

Since it already given the other two number

The equation is:

43 + 92.7 + x = 180

Adding both number together : 43 + 92.7

135.7 + x = 180

Subtract 135.7 from both sides

135.7 -135.7 +x = 180-135.7  

x = 44.3

Hence, the value in degrees of x = 44.3 °
