Multiplying radicals with like indices.

The solution of the given equation will be 2√5x(√2-1).

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

The expression will be solved as below:-

= √5x ( √8x² - 2√x)

= √5x ( 2√2x - 2√x)

= √5x(√2-1)(2√x)

= 2√5x(√2-1).

Therefore the solution of the given equation will be 2√5x(√2-1).

Step-by-step explanation:

Answer:

41.7%

Step-by-step explanation:

B. Vanessa only established some of the necessary conditions for a congruence criterion.

Step-by-step explanation:

The diagram does support the claim that \overline{KL}\cong\overline{MN}  

KL

≅  

MN

start overline, K, L, end overline, \cong, start overline, M, N, end overline because they both have two tick marks.

Step 1 is correct.

Step 2

The diagram does support the claim that \overline{LM}\cong\overline{NK}  

LM

≅  

NK

start overline, L, M, end overline, \cong, start overline, N, K, end overline because they both have a single tick mark.

Step 2 is correct.

Step 3

In this step, Vanessa claims that \triangle KLM\cong \triangle MNK△KLM≅△MNKtriangle, K, L, M, \cong, triangle, M, N, K using the side-side-side criterion. But Vanessa only established two pairs of congruent corresponding sides. To use this criterion, we must establish three pairs of congruent sides.

Vanessa would be able to use this criterion if she first established that \overline{MK}\cong\overline{KM}  

MK

≅  

KM

start overline, M, K, end overline, \cong, start overline, K, M, end overline (this can be done with the reason that line segments are congruent to themselves).

The first error Vanessa made in her proof was option B.

Vanessa only established two pairs of congruent corresponding sides

polygons are congruent if they may be identical in size and shape - that is, if their corresponding angles and sides are the same.

Congruent shapes are shapes that can be exactly equal. The corresponding facets are identical and the corresponding angles are equal.

⇒KL≅  MN   9K, L, end overline)

⇒LM≅  NK

⇒MNK△KLM≅△MNK  (triangle, K, L, M)

Answer:

18 nuts in 12 minutes, 13.5 nuts in 4 minutes and 90 nuts in one hour

Step-by-step explanation:

12 min :

12/6 = 2    

2 x 9 = 18 nuts in 12 minuts

4 min:

6/4 = 1.5

1.5 x 9 = 13.5 nuts in 4 minutes

(round to 13 if whole nuts only)

1 hour:

1 hour = 60 mins

60/6 = 10

9 x 10 = 90 nuts in one hour

Answer:

(-5 1 0 0) and (-3 0 1 0)

Step-by-step explanation:

Based on my memory,  you can use the dot product to find orthogonality meaning

u1 . u2 = 0

In this case, we let u be the arbitrary vector represented by (x y z w)

u . (1 5 3 0) can be expressed as an equation given by:

{(x y z w) | x + 5y + 3z  + 0w= 0}

We solve this equation letting y = s and z = t and x = -5s -3t

Reconstruct this according to their variable will give

(-5 1 0 0)s + (-3 0 1 0)t = 0

So the basis vectors are (-5 1 0 0) and (-3 0 1 0).

Let c1 and c2 be arbitrary constants:

if you solve for c1(-5 1 0 0) + c2(-3 0 1 0) = 0

c1 and c2 should have only trivial solution, which proves its

linear independence and so it forms a basis vector space.

Answer:

[tex]\boxed {\boxed {\sf x \approx 105.3}}[/tex]

Step-by-step explanation:

To solve for x, remember the right triangle trigonometry ratios (soh-cah-toa).

If we look at the angle given (θ), then we see that 36 is adjacent or next to the 70° angle. x is the hypotenuse because it is opposite the right angle. So, we have to use cosine (adjacent and hypotenuse).

[tex]cos (\theta)=\frac {adjacent}{hypotenuse}[/tex]

[tex]cos(70)=\frac{36}{x}[/tex]

Cross multiply. (Multiply the first numerator by the second denominator. Then, multiply the first denominator by the second numerator).

[tex]\frac{cos(70)}{1}=\frac{36}{x}[/tex]

[tex]cos(70)*x= 36[/tex]

Since we want to solve for x, we must isolate the variable. Divide both sides by the cosine of 70.

[tex]\frac{cos(70)*x}{cos(70)}=\frac{ 36}{cos(70)}\\x= 105.2569584[/tex]

Round to the nearest tenth. The 5 in the hundredth place tells us to round the 2 to a 3.

[tex]x \approx 105.3[/tex]

x is about 105.3
