Answer:

2.7 x 10^-4 = 0.00027

Step-by-step explanation:

This equation is already in standard form. So if you're looking for the answer, there it is.

Answer:

Graphically.

Step-by-step explanation:

We have the equations:

(x + 6)^2 = -12*(y + 2)

(x^2/81) + (y^2/100) = 1

First, we can see that the second one is an ellipse, and we can write it as:

(x/9)^2 + (y/10)^2 = 1

This adds some complexity to our problem.

The first equation is just a quadratic equation, that we can write in standard form as:

y = (x^2 + 12*x + 36)/(-12) - 2

y = (-1/12)*x^2 - x - 5

Then our two equations are:

(x/9)^2 + (y/10)^2 = 1

y = (-1/12)*x^2 - x - 5

This is actually really hard to solve analytically, we may end with a quartic equation or something like that (this happens for the nature of the ellipse equation)

So now that we have two rather simple equations that we know how to graph (or that we can just input the equations in a program and graph them) we can find the intersections visually.

You can see the graph of this below:

Of course, this only works to find estimations for the intersections, where one intersection is (3.35, -9.28) and the other is at (-8.69, -2.6)

Answer:

q = ± [tex]\sqrt{\frac{p}{2} }[/tex]

Step-by-step explanation:

Given

p = 2q² ( divide both sides by 2 )

[tex]\frac{p}{2}[/tex] = q² ( take the square root of both sides )

± [tex]\frac{p}{2}[/tex] = q

Answer:

q = +√p/2

Step-by-step explanation:

p = 2q²

divide both sides by 2 and root we get,

√p/2 = √2q²/2

√p/2 = q

q = +√p/2

Thus, q = +√p/2

Answer:

Step-by-step explanation:

1) 3(x + 2 ) +4  = 31

3*x + 2*3 + 4 = 31

3x + 6 + 4 = 31

  3x + 10   = 31           {Subtract 10 from both sides}

          3x = 31 - 10

         3x = 21        {divide both sides by 3}

          x = 21/3

x = 7

This equation has one solution

2) 3x + 1 = 3x + 9

Subtract 3x form both sides

3x + 1 -3x = 3x + 9 - 3x

1 ≠ 9

There is no solution for this equation.

3) 2x - 4 = 2x -4

This equation has many solution

Answer:

wy+wz+xy+xz

Step-by-step explanation:

C.) wy+wz+xy+xz  could be factored by grouping.

Method of factorization by grouping the terms:

(i) From the groups of the given expression a factor can be taken out from each group.

(ii) Factorize each group.

(iii) Now take out the factor common to group formed.

= wy + wz + xy + xz

= w(y+z) + x(y+z)

Answer:

3/ 8 ; 3/8

Step-by-step explanation:

MATHEMATICS

vowels in mathematics = (A, E, I)

letters in mathematics = (M, A, T, H, E, I, C, S)

Probability = required outcome / Total possible outcomes

Required outcome = vowels in mathematics = 3

Total possible outcomes = letters in mathematics = 8

Probability of drawing a vowel letter tiles = 3/8

2.)

Spinner division :

Red = 4 ; white =2 ; green = 1 ; blue = 1

Total divisions = 8

Probability (landing on blue) = number of blue / total

P(landing on blue) = 1 / 8

P(landing on white) = 2/ 8 = 1/4

P(landing on blue or white) = 1/8 + 2/8 = 3/8

Answer:

A. Line r intersects line p

Step-by-step explanation:

to find the second graph multiply the slope of line p by -10

slope is 1/5 or 0.2

So,

0.2 * -10 = -2

slope of second line is -2

Answer:

area = 147.03 cm²

Step-by-step explanation:

area =16.9 x 8.7 = 147.03 cm²

Answer:

147.03cm

Step-by-step explanation:

A parallelogram is just a tilted rectangle, so it uses the same formula, base times height.

This would be 8.7 × 16.9

 87 × 169 = 14703

move the decimal to get

8.7 × 16.9 = 147.03

the area of the shape is 147.03 cm, don't forget the cm sign!

good luck my friend :D

Step-by-step explanation:

Answer:

375 represents the amount Ralph paid for 3 bags of potato and 4 candy bars

Bag of potato = 45 cent

Candy = 60 cents

Step-by-step explanation:

375 represents the amount Ralph paid for 3 bags of potato and 4 candy bars

3p + 4b = 375 - - (1)

4p + 2b = 300 ---(2)

From (2)

4p = 300 - 2b

p = 75 - 0.5b

Put b = 75 - 0.5b

3(75 - 0.5b) + 4b = 375

225 - 1.5b + 4b = 375

225 + 2.5b = 375

2.5b = 375 - 225

2.5b = 150

b = 150 / 2.5

b = 60

3p + 4(60) = 375

3p + 240 = 375

3p = 375 - 240

3p = 135

p = 45

Bag of potato = 45 cent

Candy = 60 cents

Applying the inscribed angle theorem, the missing angles are:

Based on the inscribed angle theorem, we have the following relationships:

Given the following:

Find m(RS):

m(RS) = 180 - m(RU)

Substitute

m(RS) = 180 - 50

m(RS) = 130°

Find m∠RUS:

m∠RUS = 1/2(m(RS) [inscribed angle theorem]

Substitute

m∠RUS = 1/2(130)

m∠RUS = 65°

Find m∠UST:

m∠UST = 1/2(m(UT))

Substitute

m∠UST = 1/2(30)

m∠UST = 15°

Answer:

(2, 8)  and (3, 11)    --- > For example

Step-by-step explanation:

Plug in any number for x

I will use 2.

So if the equation is y = 3x + 2, then the new equation will be ...

y = 3(2) + 2

y = 6 + 2

y = 8     ----> One coordinate can be (2, 8)

Another number you could use is 3.

y = 3(3) + 2

y = 9 + 2

y = 11    ----> Another coordinate may be (3, 11)
