Answer:

Step-by-step explanation:

f(x) = -x² · (3x + 2)²

Plug in -2 for x...

f(-2) = -(-2)² · (3(-2) + 2)²

PEMDAS tells us to solve what's in the parenthesis first...

f(-2) = -(4) · (-4)²

Then we solve...

f(-2) = -4 · 16

f(-2) = -64

Your answer is -64

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:

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}

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:

z = 35

Step-by-step explanation:

Use the triangle angle sum theorem which states that the interior angles of a triangle sum to 180 degrees. The angles it refers to are the angle measures at each vertex. (Each point of the triangle)

You do not need x and y for this question. They are not angle measures at the vertex.

22+19+104+ z = 180. Combine like terms.

145+z= 180. Subtract 145 from both sides.

z= 35

Step-by-step explanation:

Answer:

Step-by-step explanation:

Michael C is correct, but you were asking about the "point slope" form

y - y1 = m(x-x1)

As Michael stated, the slope intercept form will be y = -3x + b

since the amount decreases by $3 per day...

Our slope is -3 so m=-3

We have a point (x1,y1) = (14, 68)

y-68 = -3(x-14)

y-68 = -3x + 42

y = -3x + 110
