Answer:

Exact: 2sqrt(5)

Approximate: 4.472

Step-by-step explanation:

The side of the square is the hypotenuse of a right triangle with legs of lengths 2 and 4.

c^2 = a^2 + b^2

c^2 = 2^2 + 4^2

c^2 = 4 + 16

c^2 = 20

c = sqrt(20)

c = sqrt(4 * 5)

c = 2sqrt(5) = 4.472

Answer:

x-3

Step-by-step explanation:

x²-6x+9 is equal to (x-3)²

The square root of any term that is positive is equal to the absolute value of the term. If x is greater or equal to 3, it makes the term positive.

So the root of x²-6x+9 is x-3

Step-by-step explanation:

This question uses the term absolute value.

Think of it as a form of distance. If the thing inside an Absolute value bracket is negative, absolute value will make is positive. If it is positive, it will stay the same. Thinking of this, we can solve the problem quite easily.

Answer: the Temperature on Tuesday is 13 degrees Celsius

Answer:

Step-by-step explanation:

Strictly speaking, 15% isn't precisely the same as 0.15; 0.15 is the decimal fraction used to calculate 15% of some quantity.

15% of 52 is indeed 7.8.  $7.80 is the discount that is to be SUBTRACTED  from the regular price ($52).  Adding $7.80 to $52 is incorrect.  

Also, 52 + 7.8 - 59.8 is incorrect:  it's not an equation (but should be one), and we should be subtracting $7.80 from $52.

Answer:

Step-by-step explanation:

Answer:

B. x=8

Step-by-step explanation:

The 2 angles are consecutive interior angles, and therefore they are supplementary. This means that they add to 180 degrees.

(12x+8)+(8x+12)=180

Combine like terms. Add all the terms with a variable, then the terms without a variable.

(12x+8x)+(8+12)=180

20x+20=180

Now, solve for x by isolating x. Perform the inverse operation to both sides.

20 is being added to 20x. The inverse of addition is subtraction. Subtract 20 from both sides.

20x+20=180-20

20x=180-20

20x=160

x is being multiplied by 20. The inverse of multiplication is division. Divide both sides by 20.

20x/20=160/20

x=160/20

x=8

x is equal to 8, and B is the correct answer.

Answer:

[tex]2x - 3y = 12[/tex]

[tex]-4(2x - 3y) = -4(12)[/tex]

Step-by-step explanation:

Given

[tex]y = \frac{2}{3}x - 4[/tex]

Required

Equivalents of the given equation;

We start by multiply both sides of the equation by 3

[tex]3* y = 3(\frac{2}{3}x - 4)[/tex]

[tex]3y = 3 * \frac{2}{3}x - 3 * 4[/tex]

[tex]3y = 2x - 12[/tex] ---- Equation 1

Subtract 3y from both sides

[tex]-3y + 3y = 2x - 12 - 3y[/tex]

[tex]0 = 2x - 12 - 3y[/tex]

Add 12 to both sides

[tex]12 + 0 = 2x - 12 - 3y + 12[/tex]

[tex]12 = 2x - 3y[/tex]

Rearrange:

[tex]2x - 3y = 12[/tex] ---- This is equivalent to the given equation;

Multiply both sides of the above equation by -4

[tex]2x - 3y = 12[/tex]

[tex]-4(2x - 3y) = -4(12)[/tex]  ---- This is also equivalent to the given equation;

From the list of given options, only these two are equivalent to [tex]y = \frac{2}{3}x - 4[/tex]

Step-by-step explanation:

the fireplace would have 24 bricks on the 10th row

Answer:

27 bricks

Step-by-step explanation:

y= 54- 3(x-1)

y= 57- 3x

is the function, y= number of bricks on the xth row, x= row number above the bottom one

x=10 ⇒ y= 57 - 3*10 ⇒ y= 27 bricks

x x y = (13 i + 4 j - 9 k) x (- i + 7 j - 4 k)

Distribute the cross product:

x x y = 13*(-1) (i x i) + 4*(-1) (j x i) + (-9)*(-1) (k x i)

........... + 13*7 (i x j) + 4*7 (j x j) + (-9)*7 (k x j)

........... + 13*(-4) (i x k) + 4*(-4) (j x k) + (-9)*(-4) (k x k)

x x y = -13 (i x i) - 4 (j x i) + 9 (k x i)

........... + 91 (i x j) + 28 (j x j) - 63 (k x j)

........... - 52 (i x k) - 16 (j x k) + 36 (k x k)

By definition of the cross product, we have

i x i = j x j = k x k = 0

i x j = k

j x k = i

k x i = j

and for any two vectors x and y, the product is anti-symmetric:

x x y = -(y x x)

This makes the products on the "diagonal" vanish, and we can condense terms using the anti-symmetry property:

x x y = (4 + 91) (i x j) + (9 + 52) (k x i) + (63 - 16) (j x k)

x x y = 95 k + 61 j + 47 i

x x y = 47 i + 61 j + 95 k
