Step-by-step explanation:

Answer:

-2

Step-by-step explanation:

If f(x) = 2x² + 4x - 2

f(-2) = 2(-2)² + 4(-2) - 2

f(-2) = 2(4) + 4(-2) - 2

f(-2) = 8 - 8 - 2

f(-2) = -2

Answer:

It is -18

Step-by-step explanation:

[tex]f(x) = - 2 {x}^{2} + 4x - 2[/tex]

when x is -2, f(x) is f(-2):

[tex]f( - 2) = - 2 {( - 2)}^{2} + 4( - 2) - 2 \\ \\ f( - 2) = - 8 - 8 - 2 \\ \\ f( - 2) = - 18[/tex]

Answer:

k = [tex]\frac{1}{9}[/tex]

Step-by-step explanation:

Using the discriminant

Δ = b² - 4ac

For a repeated real solution then

b² - 4ac = 0

Given

16x² - [tex]\frac{8}{3}[/tex] x + k = 0

with a = 16, b = - [tex]\frac{8}{3}[/tex] , c = k

(- [tex]\frac{8}{3}[/tex] )² - ( 4 × 16 × k) = 0

[tex]\frac{64}{9}[/tex] - 64k = 0 ( subtract [tex]\frac{64}{9}[/tex] from both sides )

- 64k = - [tex]\frac{64}{9}[/tex] ( divide both sides by - 64 )

k = [tex]\frac{1}{9}[/tex]

Answer:

Answer:

-4/3

Step-by-step explanation:

To find the slope you do rise over run. The line goes down by four and to the right by three between the two points so the slope is -4/3/

Answer:

3p-2

Step-by-step explanation:

................

Answer:

3p - 2

Step-by-step explanation:

[tex]5p - 3 - (1 + p) + (2 - p)[/tex]

[tex]5p - 3 - 1 - p + (2 - p)[/tex]

[tex]5p - 3 - 1 - p + 2 - p[/tex]

➡️ [tex] - 4 + 2[/tex]

➡️ [tex] = - 2[/tex]

[tex] = 3p - 2[/tex]

First calculate distances or lengths(Refer to attachment)

[tex]\\ \sf\longmapsto Perimeter=Sum\:of\:sides[/tex]

[tex]\\ \sf\longmapsto 5.3+9+11+9+9.7[/tex]

[tex]\\ \sf\longmapsto 15+29[/tex]

[tex]\\ \sf\longmapsto 44[/tex]

B:-

Refer to the attchment

C:-

To find the perimeter first find the length of each side:

The perimeter is:

Use midpoint formula:

The point is (2.5, 3.5)

Answer:

21

Step-by-step explanation:

s=2

so, v=2+19

19+2=21

Answer:

x = 7 1/2

Step-by-step explanation:

We can use proportions to solve

12         5

----- = -----

18          x

Using cross products

12x = 18*5

12x = 90

Divide by 12

12x/12 = 90/12

x = 7 1/2

12/18 = 5/x

12x = 18 × 5

12x = 90

x = 90 ÷ 12

x = 7,5 => x = 7 1/2

There are exactly 81 terms in the sequence.

Start counting with 1 (like non-computer people).

First term is [tex]1=2^0[/tex].

Second term is [tex]2=2^1[/tex].

Third term is [tex]2^2[/tex].

Fourth term is [tex]2^3[/tex].

In general the i-th term is [tex]2^{i - 1}[/tex].

Hope this helps :)

Answer:

  g(f(x)) = √((x²+5)/(x²+4))

Step-by-step explanation:

  [tex]g(f(x))=g(\dfrac{1}{x^2+4})=\sqrt{\dfrac{1}{x^2+4}+1}=\sqrt{\dfrac{1+x^2+4}{x^2+4}}\\\\\boxed{g(f(x))=\sqrt{\dfrac{x^2+5}{x^2+4}}}[/tex]

I prefer this compact form, but some may want the denominator rationalized. This means the expression becomes ...

  [tex]g(f(x))=\sqrt{\dfrac{(x^2+5)(x^2+4)}{(x^2+4)^2}}\\\\\boxed{g(f(x))=\dfrac{\sqrt{x^4+9x^2+20}}{x^2+4}}[/tex]

Answer:

v = 3.14x²y

Step-by-step explanation:

volume cylinder = πr²h

r = 2x ÷ 2 = x

h = y

Answer:

It is 3.14x²y

Step-by-step explanation:

formular:

[tex]{ \bf{V = \pi {r}^{2} h}}[/tex]

r is radius, r = 2x/2 = x

h is height, h = y

[tex]{ \sf{V = (3.14) \times ( {x}^{2} ) \times y}} \\ V = 3.14 {x}^{2} y[/tex]

Hi :)

m is a variable

m is defined as 8.6

substitued m

8.6 + 7.5 = 16.1

Answer:

m+7.5 = ? when m = 8.6

Sub 8.6 in equation for m and you get

8.6 + 7.5 = 16.1

Answer:

Equation is 3y = x + 19

Step-by-step explanation:

General equation:

[tex]y = mx + c[/tex]

For slope, m:

[tex]m_{1} \times m_{2} = - 1[/tex]

but m1 is -3:

[tex] - 3m_{2} = - 1 \\ m_{2} = \frac{1}{3} [/tex]

For y-intercept, c:

[tex]y = mx + c \\ 6 = ( - 1 \times \frac{1}{3} ) + c \\ \\ c = 6 + \frac{1}{3} \\ \\ c = \frac{19}{3} [/tex]

equation:

[tex]{ \sf{y = \frac{1}{3}x + \frac{19}{3} }} \\ \\ 3y = x + 19[/tex]

Answer:

-1

Step-by-step explanation:

f(-1) = 2|-1| + 3(-1)

|-1| = 1

=> f(-1) = 2(1) - 3

=> f(-1) = 2 - 3

=> f(-1) = -1

Answer:

Step-by-step explanation:

Given:

To find:

Use long division:

2x + 1  | (8x³ + 16x² − 15

           | 8x³ + 4x²

                     12x² + 0x - 15

                     12x² + 6x

                               -6x - 15

                               -6x - 3

                                      -12

4x² + 6x - 3 remainder -12
