What is the standard equation of a circle with center (-2,0) and radius 4?

The answer is x=-10

Step-by-step explanation:

the reasoning is you do the inverse or opposite of three to both sides so you add +3 to both sides so the -3 and the +3 would cancel out then you would add +3 to the integer -23 and get -20 next is you divide by 2 on each side so you 2÷2 which would cancel out and then -20÷2 which would equal -10

Hence the answer is x=-10

If the solutions to a quadratic equation were -2 and 3 then,

А. The x-intercepts of the graph are also - 2 and 3.

C. The factors are (x - 2) and (x + 3).

The equation is ax² + bx + c = 0 is x² = x - 6 = 0.

A quadratic equation is an algebraic expression in the form of variables and constants.

A quadratic equation has two roots as its degree is two.

Given, The solutions to a quadratic equation were -2 and 3.

∴ The quadratic equation ax² + bx + c = (x + 2)(x - 3).

So,  The x-intercepts of the graph are also - 2 and 3.

The factors are (x - 2) and (x + 3).

The equation is ax² + bx + c = 0

=  (x + 2)(x - 3) = 0

= x² - 3x + 2x - 6 = 0

= x² = x - 6 = 0.

Answer:

B (- 5, 7 )

Step-by-step explanation:

Using the midpoint formula, then equate x and y coordinates

let coordinates of B = (x, y ) , then

[tex]\frac{x+1}{2}[/tex] = - 2 ( multiply both sides by 2 )

x + 1 = - 4 ( subtract 1 from both sides )

x = - 5

[tex]\frac{y-7}{2}[/tex] = 0

y - 7 = 0 ( add 7 to both sides )

y = 7

Coordinates of B = (- 5, 7 )

Answer:

1803 square meter

Step-by-step explanation:

The surface area of a cone

A=πr(r+V(h2+r2))

where A is the surface area, r is the radius and h is the height

Given that the height of 54 meters and a diameter of 18 meters, the radius is half the diameter hence

radius = 18/2 = 9 m

A = 9π (9 + V(54^2 + 9^2))

= 9π (9 + V2997)

= 9π (9 + 54.74486)

= 1803.068976 Square meters

To the nearest square meter

A = 1803

Answer:

y=2(x + 2))^2 - 9

Step-by-step explanation:

So, whenever two negative signs are right next to each other, they make a positive. However, when they are alone, they stay negative.

With this, y=2(x-(-2))^2 + (-9) --> y=2(x + 2))^2 -9

[tex]x=6.183ft[/tex]

Step-by-step explanation:

From the question we are told that:

Angel of side [tex]T=90[/tex]

Angel of side [tex]R=82[/tex]

Length Side [tex]TR=44[/tex]

Generally the equation for Angle of side ST [tex]\theta[/tex] is mathematically given by

Since Angle in Triangle =180 therefore

 [tex]\theta=180-(90+82)[/tex]

 [tex]\theta=8[/tex]

Therefore Applying sine rule to get Length of ST x

 [tex]\frac{x}{sin\theta}=\frac{TR}{sin82}[/tex]

 [tex]x=\frac{44}{sin82}*sin8[/tex]

 [tex]x=6.183ft[/tex]

Answer:

y=50 but i dont know x, sorry about that its cause im in class rn lol

Answer:

x= 127

y = 50

Step-by-step explanation:

y = 180 -130(angles on a straight line)

y= 50

x= 360-(123+60+50). angles in a quadrilateral

x = 360- 233

x= 127

Answer:

10 miles

Step-by-step explanation:

6² + 8² = x²

36 + 64 = 100

√100 = 10

Answer:

6) 1/2 + 1/2 + 1/2 + 1/2 = 4/2 = 2 inches.

7)  5/8 + 5/8 + 5/8 = 15/8 = 1 7/8 inches.

8)  We've added the 1/2-inch crystals together and the 5/8-inch crystals together.  Adding together the 3/4-inch crystals we have:

3/4 + 3/4 + 3/4 = 9/4 = 2 1/4 inches

Adding together the 3/8-inch crystals we have:

3/8 + 3/8 + 3/8 = 9/8 = 1 1/8 inches.

Totaling what we have:

2 + 1 7/8 + 2 1/4 + 1 1/8

= 2 + 1 7/8 + 2 2/8 + 1 1/8 (you can only add fractions if they have common denominators)

= 6 + 7/8 + 2/8 + 1/8 (add the whole numbers together)

= 6 10/8 = 6 + 1 2/8 = 7 2/8 = 7 1/4 inches.

9)  To find an average, we add all of the data points together and divide by the number of data points.  We added them in number 8.  Now we divide this total, 7 1/4, by 13:

7 1/4 ÷ 13 = 29/4 ÷ 13/1 = 29/4 × 1/13 = 29/52 inches average for the crystals.

Step-by-step explanation:

convert either gram into kg or kg into gram

lets convert kg into g

1 kg=1000g

20kg=1000*24g

=20000g

450/20000*100%

450/200%

2.25%

first convert 450 g to kg = 0.45 kg

Now 0.45 kg as a. percentage of 20 kg = 0.45/20×100= 2.25%

Step-by-step explanation:

Let the number of mangoes owned by Tulsa be T and that by Julie be J

If Tulsa has 4 times as many mangoes as Julie then

T = 4J

Tulsa bought 6 more mangoes. She now has 5 time as many mangoes as Julie

T + 6 = 5J

Solve both equations simultaneously by substitution

4J + 6 = 5J

Collect like terms

6 = 5J- 4J

J = 6

Since

T = 4J

T = 4 * 6

= 24

Hence Tulsa had 24 mangoes at first

Sum of 2 fifths of x and 6x and 6 in algebraic expression = 2/5 x +6x +6

Answer:

(14x+12)/5

Step-by-step explanation:

2 fifth of x = 2/5 * x= 2x/5

2 fifth of 6x = 2/5 * 6x = 12x/5

2 fifth of 6 = 2/5 * 6 = 12/5

2x/5 + 12x/5 + 12/5

= (2x+12x+12)/5

= (14x+12)/5

Step-by-step explanation:

Let y represent the number of green shirts.

So y+5 is the number of blue shirts.

And y-2 is the number of yellow shirts.

And we have 5 red shirts.

Therefore,

7+5+y+y-2+y=28

12-2+3y=28

10+3y=28

Answer:

The df values for the A x B interaction are also 3,40

Step-by-step explanation:

The F-value for Factor A has df = 1, 40

The F-value for Factor B has df = 3, 40.

The df values for the A x B interaction are also 3,40

This is because the source of variation between columns has ( c- 1); rc(n-1) degrees of freedom and  the source of variation between  rows has (r-1); rc(n-1) degrees of freedom and the  source of variation of interaction

(between rows and columns)  has ( c-1) ( r-1); rc(n-1) degrees of freedom.

Therefore

Factor A:  ( c- 1); rc(n-1)    = 1,40

Factor B:    (r-1); rc(n-1)     = 3,40

Interaction : ( c-1) ( r-1); rc(n-1)   =  3*1,(40)= 3,40

where c refers to columns , r refers to rows and n refers to the total sample size.
