Answer:

100°

Step-by-step explanation:

Since x and the 100 degree angle which is highlighted in blue are vertical to each other, they are parallel to each other as it is vertically opposite angles.

If they are parallel, it means

Angle highlighted in blue = 100°

x = 100°

Answer:

h(1) = 1

h(4) = 5

Step-by-step explanation:

Since 1 is in the interval 1 ≤ x ≤ 3, you must substitute 1 into the expression  [tex]x^{3}[/tex]

So, h(1) = [tex]1^{3}[/tex] = 1

Since 4 is in the interval x > 3, and all values of x > 3 gives an output of 5, then h(4) = 5

Look at the graph bellow

Step-by-step explanation:

use the slope and y-intercept to graph.

Step-by-step explanation:

We have to list the elements present in each set.

A = {multiples of 3 between 20 and 32}

A = {21, 24, 27, 30}

B = {odd numbers between 20 and 32}

B = {21, 23, 25, 27, 29}

C = {even numbers between 20 and 32}

C = {20, 22, 24, 26, 28, 30, 32}

a) list the members of A ∪ B

This means to select the elements of sets A and B

A ∪ B = {21, 23, 24, 25, 27, 29, 30}

b) list the members of A ∩ C

This means to only pick the elements that are present in both A and B

A ∩ C = {24, 30}

Answer:

Part A

The equation of the parabola in standard form is f(x) = 0.5·x² + x - 7.5

Part B

The equation of the parabola in factored form is f(x) = 0.5·(x + 5)·(x - 3)

Step-by-step explanation:

The coordinates of the vertex of the parabola, (h, k) = (-1, -8)

The zeros of the parabola = -5, 3

Part A

The quadratic equation representing the parabola can be written as follows;

y = a·(x - h)² + k

The standard form of the equation is f(x) = a·x² + b·x + c

k = c - b²/(4·a)

h = -b/(2·a)

c = k + a·h² = -8 + a

From the zeros of the parabola, we have;

f(-5) = a × (-5)² + b×(-5) + c = 25·a - 5·b + c = 0

f(3) = a × (3)² + b×(3) + c = 9·a + 3·b + c = 0

Therefore, we have;

25·a - 5·b + c = 0...(1)

9·a + 3·b + c = 0...(2)

From which we have;

25·a - 5·b + c = 25·a - 5·b - 8 + a = 26·a - 5·b - 8 = 0

9·a + 3·b + c = 9·a + 3·b - 8 + a = 10·a + 3·b - 8 = 0

We then have;

26·a - 5·b = 8...(3)

10·a + 3·b = 8...(4)

Making 'b', the subject of both equations (3) and (4), equating the values, we find the value of 'a' as follows;

From equation (3), we have;

26·a - 5·b = 8

∴ b = (26·a - 8)/5

From equation (4), we have;

10·a + 3·b = 8

∴ b = (8 - 10·a)/3

From b = b, by transitive property, we have;

(26·a - 8)/5 = (8 - 10·a)/3

3 × (26·a - 8) = 5 × (8 - 10·a)

78·a - 24 = 40 - 50·a

∴ 128·a = 64

a = 64/128 = 1/2 = 0.5

a = 0.5

∴ b = (26·a - 8)/5 = (26 × 0.5  - 8)/5 = (13 - 8)/5 = 1

b = 1

c = -8 + a

∴ c = -8 + 0.5 = -7.5

c = -7.5

The equation of the parabola in standard form is therefore presented as follows;

f(x) = 0.5·x² + x - 7.5

Part B

The equation of the parabola in factored form is given as follows;

With the aid of a graphing calculator, we have;

f(x) = 0.5·x² + x - 7.5 = 0.5×(x² + 2·x - 15) = 0.5·(x + 5)·(x - 3)

The equation of the parabola in factored form is f(x) = 0.5·(x + 5)·(x - 3)

Answer:

HG = 2[tex]\sqrt{2}[/tex]

Step-by-step explanation:

Using the cosine ratio in the right triangle and the exact value

cos60° = [tex]\frac{1}{2}[/tex] , then

cos60° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{GI}{HG}[/tex] = [tex]\frac{\sqrt{2} }{HG}[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )

HG = 2[tex]\sqrt{2}[/tex]

Use trigonometry.

Angle H = 30 degrees

sin (30) = sqrt{2}/HG

HG = sqrt{2}/sin (30)

HG = 2.8284271248

HG = 2•sqrt{2}

Answer:

increase of 50%

Step-by-step explanation:

its increasing cuz 75 is more than 50 and its 50% cuz 75-50 is 25 so you know it increased by 25 meals so you need to find what percent 25 is of 50 and 25 is 50% of 50

Answer:

50%

Step-by-step explanation:

half of 50 is the same as 50% of 50

so...

25 = 50% of 50

therefore...

50 + 25 is the same as 50 + 50%

Answer:

Step-by-step explanation:

The marked angles form a linear pair, so have a sum of 180°.

  (4a +10) +(6a) = 180

  10a = 170 . . . . . . . . . . subtract 10

  a = 17 . . . . . . . . . . . . . divide by 10

__

Then the measure of angle ABC is ...

  ∠ABC = 4a +10 = 4(17) +10 = 68 +10 . . . . . substitute 17 for 'a'

  ∠ABC = 78°

Answer:

Step-by-step explanation:

Option A  is the correct answer because the ratio between the opposite side and the hypotenuse side is correct.

Triangle :

A right-angled triangle is a triangle, that has one of its interior angles equal to 90 degrees or any one angle is a right angle. Therefore, this triangle is also called the right triangle or 90-degree triangle. The right triangle plays an important role in trigonometry. Let us learn more about this triangle in this article.

A triangle with Side lengths a unit, b units, and c units.

"Opposite" is opposite to the angle θ

"Adjacent" is adjacent (next to) to the angle θ

"Hypotenuse" is the long one

A)

Sin 55 = a/c

Sin  θ = opposite / hypotenuse

Option A ) is correct  Sin 55 = a/c  

B)

Cos(55°)=c/b

Cos θ =  Adjacent / hypotenuse

Cos 55 = c/ b is not equal to the Adjacent / hypotenuse

Option B)  is not a correct answer because the ratio is between  Adjacent and Hypotenuse.  

C)

Cos(55°)=a/b

Cos θ =  Adjacent / hypotenuse

Cos 55 = a/ b is not equal to the Adjacent / hypotenuse

Option C)  is not a correct answer because the ratio is between Adjacent and Hypotenuse.  

D)

Tan(55°)=c/a

Tan θ  = Opposite / Adjacent

Tan 55 =  c/a is not equal to the  Opposite / Adjacent

Option D)  is not a correct answer because the ratio is between Opposite and Adjacent.
