The statement that "subset h of a vector space v is a subspace of v if the zero vector is in h" is true.

A subspace is a vector space that is also encompassed within another vector space.

So, while each subspace is a vector space in its own right, it is also defined with respect to another (bigger) vector space.

Three components must be demonstrated to prove that a subset is a subspace:

Additionally, demonstrate that it is closed.

Show that it is closed when scalar multiplication is used.

Show that vector 0 is a part of the subset.

As it is stated in the question;

h represents a subset of the vector space v.

The zero vector is contained in h.

This implies that h must be in the v subspace.

Hence, the statement that "subset h of a vector space v is a subspace of v if the zero vector is in h" is true.

Answer:

p = 5 ; q = -11

Step-by-step explanation:

      [tex]\sf (a - b)^2 = a^2 + b^2 - 2ab\\\\(\sqrt{5}-3)^2 = (\sqrt{5})^2+3^2-2*\sqrt{5}*3[/tex]

[tex]\sf \dfrac{(\sqrt{5}-3)^2}{\sqrt{5}+1}=\dfrac{14-6\sqrt{5}}{\sqrt{5}+1}[/tex]

 Multiply the denominator and the numerator by (√5 - 1).

                 [tex]\sf= \dfrac{(14-6\sqrt{5})(\sqrt{5}-1)}{(\sqrt{5}+1)(\sqrt{5}-1)}\\\\\\= \dfrac{14*\sqrt{5}-14*1-6\sqrt{5}*\sqrt{5}+6\sqrt{5}*1}{(\sqrt{5})^2-1^2}\\\\\\=\dfrac{14\sqrt{5}-14-6*5+6\sqrt{5}}{5-1}\\\\\\=\dfrac{14\sqrt{5}+6\sqrt{5}-14-30}{4}[/tex]

                 [tex]\sf = \dfrac{(14+6)\sqrt{5}-44}{4}\\\\\\= \dfrac{20\sqrt{5}-44}{4}\\\\=\dfrac{20\sqrt{5}}{4}-\dfrac{44}{4}\\\\\\=5\sqrt{5}-11[/tex]

A constant is the number with no variable attached to it, in this case, 5.

By solving a linear equation, we will see that the two consecutive integers are -8 and -7

We know that the sum of an integer and 6 times the next consecutive integer is -50.

So if x is the integer, x + 1 will be the next consecutive integer, then we can write the equation:

x + 6*(x + 1) = -50

So we need to solve a linear equation, it will give:

x + 6x + 6 = -50

7x + 6 = -50

7x = -50 - 6

7x = -56

x = -56/7 = -8

Then the next integer is:

x + 1 = -8 + 1 = -7

The total yield for an acre, T, in pounds as a function of the number of walnut tree per acre, x is given by T = -1.5x² + 95x.

In order to solve this word problem, we would assign variables to the number of walnut tree per acre and total yield for an acre, and then translate the word problem into algebraic equation as follows:

Mathematically, the total yield for an acre can be calculated by using this mathematical expression:

Total yield for an acre (T) = yield of each tree × number of trees per acre

Substituting the given parameters into the mathematical expression, we have the following;

Total yield for an acre (T) = [50 - 1.5(x - 30)] × x

Opening the bracket, we have:

Total yield for an acre (T) = [50 - 1.5x + 45] × x

Total yield for an acre (T) = 50x - 1.5x² + 45x

Next, we would rearrange the function by collecting like terms and simplifying as follows:

Total yield for an acre (T) = -1.5x² + (50x + 45x)

Total yield for an acre (T) = -1.5x² + 95x

The length of the fence (including the gates) that was built around the park is (4w + 50) feet.

Here, we are given that a rectangular park is w ft wide and the park is 25 ft longer than its wide.

Thus, the length of the park = (w + 25) ft

Now, the park has to be fenced along all of its sides. Thus, we need to find the perimeter of the rectangular park.

The perimeter of a rectangle is given as-

2( length + breadth)

Thus, here, the perimeter will be-

2( w + 25 + w )

= 2( 2w + 25 )

= 4w + 50

Thus, the length of the fence (including the gates) that was built around the park is (4w + 50) feet.

Answer:

3. ∠A = 110°

4. ∠H = 70°

5. ∠D = 70°

6. ∠F = 70°

Step-by-step explanation:

In a parallelogram, adjacent angles are supplementary (sum to 180°).

⇒ ∠A + ∠B = 180°

⇒ ∠A + 70° = 180°

⇒ ∠A = 110°

In a parallelogram, opposite angles are congruent.

⇒ ∠C = ∠A = 110°

⇒ ∠D = ∠B = 70°

If two parallelograms are similar, their corresponding interior angles are congruent.

⇒ ∠A = ∠E = 110°

⇒ ∠B = ∠F = 70°

⇒ ∠C = ∠G = 110°

⇒ ∠D = ∠H = 70°

Answer:

Workers to be be added to finish the work in 24 hours = 348

Step-by-step explanation:

This is a problem involving inverse proportion

Here the number of days required to complete the job is inversely proportional to the number of workers- the more the workers, the less time it takes

We can state this as:
[tex]D \propto \dfrac{1}{N}[/tex]

where D = time in days required to complete the job and N is the number of workers that can do this in D days

The equation relating D and N can be stated as

[tex]D = k \dfrac{1}{N}[/tex]

This gives us k = D x N  (multiply by N both sides)

where k is a constant known as the constant of proportionality

Given data that D = 30 when N = 12, this constant of proportionality = D x N = 30 x 12 = 360

From the equation of proportionality we also get
N = k/D

So to complete the job in 24 hours = 1 day, substitute 1 for D and 360 for k to get
N = 360/1 = 360 workers

So you will need 360-12 = 348 workers if you expect to  finish the job in 24 hours = 1 day

Answer:

6 students have their own cell phone and 3 of them can use social media.

Step-by-step explanation:

One fifth of 30 is 6. One half of six is 3.

3. The slope of the line through the  points (0, 10) & (24, 6) is  [tex]\frac{1}{4}[/tex]

4. The slope of the line through the points (0, 6) & (20, 14) is  [tex]\frac{2}{5}[/tex]

The slope of a line indicates its steepness. Slope is calculated mathematically as "rise over run" (change in y divided by change in x). The slope of a line, or a section of a line connecting two points, is a measure of its steepness.

Or. A line's slope is the ratio of how much y increases as x increases by some amount. The slope-intercept form of an equation is when the equation of a line is written in the form y = mx + b. The slope of the line is given by m. And b is the value of b in the y-intercept point (0, b).

How are the slopes calculated?

3. We know that , slope = m

[tex]m= \frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

[tex](x_{1}, y_{1})=(0, 10)\\\\(x_{2}, y_{2})=(24, 16)[/tex]

[tex]m= \frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\m= \frac{16- 10}{24 -0}\\\\m= \frac{6}{24}\\\\m=\frac{1}{4}[/tex]

4. We know that , slope = m

[tex]m= \frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

[tex](x_{1}, y_{1})=(0, 6)\\\\(x_{2}, y_{2})=(20, 14)[/tex]

[tex]m= \frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\m= \frac{14- 6}{20 -0}\\\\m= \frac{8}{20}\\\\m=\frac{2}{5}[/tex]

The scale factor for #7 is 0.5, because the dotted rectangle is half the size of the shaded one. The scale factor for #8 is 3, because the dotted triangle is 3 times as big as the shaded one.

( 5,0 ) and ( 0,4 ) are the x and y-intercept of the function 4x + 5y = 20 respectively.

The intercept of a line on a graph is simply the point at which it intersects either the x-axis or y-axis.

Given the data in the question;

Now, we find the intercepts of the equation of line, plug in y = 0 and solve for x

4x + 5y = 20

4x + 5(0) = 20

4x = 20

x = 20/4

x = 5

Hence, the x-intercept is ( 5,0 )

For the y-intercept, plug in x = 0 and solve for y

4(0) + 5y = 20

5y = 20

y = 20/5

y = 4

Hence, the y-intercept is ( 0,4 ).

The coordinates along the directed line segment is (-4, 5/3)

This involves dividing a line into proportional ratios

The points are given as:

A  = (-7, 2)

B = (2, 1)

The ratio on the segment can be represented as;

m : n = 1 : 2

So, we have the coordinates of the point that lies along the directed line segment to be

Point = 1/(m + n) * (mx₂ + nx₁, my₂ + ny₁)

So, we have:

Point  = 1/(1 + 2) * (1 * 2 + 2 * -7, 1 * 1 + 2 * 2)

Evaluate

Point  = 1/3 * (-12, 5)

Evaluate the products

six x plus fifteen y equal to minus seventy five

6x + 15y = -75

Subtract 6x from both sides

6x+15y-6x=-75-6x

15y=-75-6x
