What is the value of f(x) = 2 • 2x for f(–2)?


–0.50

0.0625

0.25

0.50

Answer:

10

Step-by-step explanation:

A = 7, B = 2

7 = 2 * 3 + 1

7 mod 2 = 1

A = 8, B = 4

8 = 4 * 2 + 0

8 mod 4 = 0

A = 13, B = 5

13 = 5 * 2 + 3

13 mod 5 = 3

A = -16, B = 26

-16 = 26 * -1 + 10

-16 mod 26 = 10

Variation can be direct, inverse or jointly

Jordan's first error is that he incorrectly calculated the value of proportionality constant

From the question, we understand that f varies directly as the square root of g.

This variation is represented as:

[tex]\mathbf{ f\ \alpha\ \frac{1}{\sqrt{g}}}[/tex]

Express as a equation

[tex]\mathbf{ f\ \ =\ k\frac{1}{\sqrt{g}}}[/tex]

When f = 4, k = 4.

So, we have:

[tex]\mathbf{ 4\ \ =\ k\frac{1}{\sqrt{4}}}[/tex]

[tex]\mathbf{ 4\ \ =\ \frac{k}{2}}[/tex]

Multiply both sides by 2

[tex]\mathbf{ k = 8}[/tex]

When g = 100, we have:

[tex]\mathbf{ f\ \ =\ k\frac{1}{\sqrt{g}}}[/tex]

[tex]\mathbf{ f\ \ =\ 8 \times \frac{1}{\sqrt{100}}}[/tex]

[tex]\mathbf{ f\ \ =\ 8 \times \frac{1}{10}}[/tex]

[tex]\mathbf{ f\ \ = 0.8}[/tex]

This means that, Jordan incorrectly calculated the value of proportionality constant

Step-by-step explanation:

We know (Ohm second law) that [tex]R= \frac{k}{d^2}[/tex] where k inlcudes the rest of the parameters (material, lenght). In our situation we have k= [tex]0.4\cdot9 \Omega mm^2[/tex]. The moment the diameter becomes 8mm R becomes

Answer:

6+4-x^2

Step-by-step explanation:

10-x^2

-x^2+10 is the answer

Answer:

C

Step-by-step explanation:

To find the x- intercept let f(x) = 0 , then

3log(x - 5) + 2 = 0 ( subtract 2 from both sides )

3log(x - 5) = - 2 ( divide both sides by 3 )

log(x - 5) = - [tex]\frac{2}{3}[/tex] , then

x - 5 = [tex]10^{-\frac{2}{3} }[/tex] ( add 5 to both sides )

x = [tex]10^{-\frac{2}{3} }[/tex] + 5 → C

7^2=49 10^2=100

49+100 = 149

sqrt(149)

Answer:

A) [tex]\sqrt{149}[/tex]

Step-by-step explanation:

Pythagorean Theorem: [tex]c^{2}[/tex] = [tex]a^{2}[/tex] + [tex]b^{2}[/tex]

c² = a² + b²

c² = 7² + 10²

c² = 49 + 100

Answer: x = 4,1

Step-by-step explanation:

Answer:

x = 4 or x = 1

Step-by-step explanation:

x² - 5x + 4 = 0

⇒ x² - 4x - x + 4 = 0

⇒ x (x - 4) - 1 (x - 4) = 0

⇒(x - 4)(x - 1) = 0

Therefore,

x - 4 = 0

⇒ x = 4

Again.

x - 1 = 0

⇒ x = 1

Hence, x = 4 or x = 1 :)

Answer:

n = {-1, 7}

Step-by-step explanation:

8n² - 56 = 48n

Subtract 48n from both sides

8n² - 48n - 56 = 0

Divide both sides by 8

n² - 6n - 7 = 0

Factor

alternately use the quadratic equation or complete the square

(n - 7)(n + 1) = 0

n = {-1, 7}
