Answer:

504 un²

Step-by-step explanation:

7 × 6 × 12 = 504

504 un²

Volume is not BH but rather LBH

So LBH = 7 * 12 * 6

Volume = 504cm³

Answer:

-5 +7x equal 12x

Step-by-step explanation:

add and complete

The x-intercepts of the function f(x) are:

Left x-intercept: (-3, 0)

Right x-intercept: (7, 0)

Given is a function, f(x) = -2(x + 3)(x - 7).

We need to find the x-intercept of the function,

To find the x-intercepts of the function f(x), we set f(x) equal to zero and solve for x:

-2(x + 3)(x - 7) = 0

Now, we can use the zero product property, which states that if a product of factors is equal to zero, then at least one of the factors must be zero.

So, we have two cases to consider:

Case 1: x + 3 = 0

Solving this equation, we subtract 3 from both sides:

x = -3

Case 2: x - 7 = 0

Solving this equation, we add 7 to both sides:

x = 7

Therefore, the x-intercepts of the function f(x) are -3 and 7.

Writing them as ordered pairs, we have:

Left x-intercept: (-3, 0)

Right x-intercept: (7, 0)

The correct answer is neither

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.

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.

⇒MNK△KLM≅△MNK  (triangle, K, L, M)

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.

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:

40+8X=50+23X

8X-23X=50-140
