Answer:

3 Ohms

Step-by-step explanation:

U1 = 5 ohm × 1.5 amps = 7.5 V

U2 = U - U1 = 12 - 7.5 = 4.5 V

R2 = U2 / I = 4.5 / 1.5 = 3 Ohms

El símbolo de grado no se usa para informar la temperatura usando la escala Kelvin, sino que se indican como Kelvin. El agua hierve a 100 grados Celsius o 212 grados Fahrenheit, o 373,15 Kelvins. El agua se congela a 0 grados Celsius o 32 grados Fahrenheit, o 273,15 Kelvins. El cero absoluto es 0 Kelvin.

Answer:

[tex]y = 120 + 0.15x[/tex]

Step-by-step explanation:

Given

[tex]Additional\ Fee = \$0.15[/tex] per vertical meter

[tex]y = fee[/tex] per x meter

[tex]x = vertical\ meter[/tex]

For:

[tex]x = 3500[/tex] --- [tex]y = 645[/tex]

Required

Determine the equation that relates y to x

Let the initial fee be represented with m

The equation that relates y to x is:

[tex]y = Initial\ Fee + Additional\ Fee * Vertical\ Meter[/tex]

This gives

[tex]y = m + 0.15 * x[/tex]

We need to first solve for m

From the question,

[tex]x = 3500[/tex] when [tex]y = 645[/tex]

So:

[tex]645 = m + 0.15 * 3500[/tex]

[tex]645 = m + 525[/tex]

Make m the subject

[tex]m = 645 - 525[/tex]

[tex]m = 120[/tex]

So, the initial fee is $120

Substitute 120 for m in [tex]y = m + 0.15 * x[/tex]

[tex]y = 120 + 0.15 * x[/tex]

[tex]y = 120 + 0.15x[/tex]

Hence, the required equation is: [tex]y = 120 + 0.15x[/tex]

Hello!

[tex]\large\boxed{x^{4}}[/tex]

Recall that:

[tex]\sqrt[z]{x^{y} }[/tex] is equal to [tex]x^{\frac{y}{z} }[/tex].  Therefore:

[tex]\sqrt[3]{x^{2} } = x^{\frac{2}{3} }[/tex]

There is also an exponent of '6' outside. According to exponential properties, when an exponent is within an exponent, you multiply them together. Therefore:

[tex](x^{\frac{2}{3} })^{6} = x^{\frac{2}{3}* 6 } = x^{\frac{12}{3} } = x^{4}[/tex]

Answer:

D, ininitely many

Step-by-step explanation:

A- incorrect since the lines intersect

B - incorrect since the lines intersect at more than one point

C - incorrect since the lines intersect at more than 2 points

D- correct since the lines intersect at infinitely many points (since they're the same line)

Answer:

D) infinitely many solutions

Step-by-step explanation:

we can see that the graphs shows two lines that are exactly one on top of the other. This means that every point on either line will also coincide with a point on the other line.

Because of this, every point on one line is also a solution on the other line, thus there are infinitely many solutions.

Answer:

  f(x) = -1/4(x +3)² -2

Step-by-step explanation:

The graph is shifted left 3 and down 2. It is also reflected over the x-axis and vertically compressed. The leading coefficient will be a negative fraction, and the offsets will replace x with x+3, and will add -2 to the scaled function.

The result is shown below.

Answer:

11

Step-by-step explanation:

36/4 = 9

9 = x-2

x = 11

Step-by-step explanation:

Perimeter = 36

length = x - 2

Perimeter of a square = 4 × length

36 = 4(x - 2)

dividing through by 4:

9 = x - 2

hence:

x = 9 + 2 = 11.

Step-by-step explanation:

There are 2 pi radians in 360 degrees:

 [tex]\frac{17\pi}{4}rad \cdot\frac{360^{\circ}}{2\pi{rad}}=765^{\circ}=45^{\circ}[/tex]

Answer: I think it 45°

Explanation:360-315=45

Answer:

yes

when the point is pugged into the equality, it works

Answer:

1

Step-by-step explanation:

The exponent is the number of times you multiply the base aka i in this case.

i = -1

Substitute -1 for i.

-1^2

-1 x -1 = 1

because when you multiply two negatives they make a positive.

20 more of her friends prefer FortNite than Among Us

Step-by-step explanation:

Lynne was wondering which game was more popular so she aksed her friends which they liked to play more, FortNite or Among Us.

She found that of the 80 people who responded:

For fortnite:

0.55 of them preferred FortNite

Hence, = 0.55 × 80 people

= 44 people preferred fortnite

For Among us

30% of them preferred Among Us.

= 30% × 80 people

= 30/100 × 80 people

= 24 people preferred Among us.

How many more of her friends prefer FortNite than Among Us?

This is calculated as:

44 - 24

= 20 more people

Hence, 20 more of her friends prefer FortNite than Among Us

Answer:

20 more of her friends prefer Forte than Among

Answer:

always true

Step-by-step explanation:

Distribute the left side

2(x + 3) = 2x + 6

Simplify the right side

5x + 6 - 3x ← collect like terms

= 2x + 6

Thus

left side = right side , so always true

Equation 2(x + 3) = 5x + 6 - 3x is an identity which is always true.

An identity is an equation which is always true, no matter what values are substituted.

Identities can be written with the sign ≡.

Given equation,

2(x + 3) = 5x + 6 - 3x

Simplifying

2x + 6 = 2x + 6

LHS = RHS

Hence, equation 2(x + 3) = 5x + 6 - 3x  is always true.

Answer:

c = [tex]\sqrt{90}[/tex]

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse c is equal to the sum of the squares on the other 2 sides, that is

c² = 9² + 3² = 81 + 9 = 90 ( take the square root of both sides )

c = [tex]\sqrt{90}[/tex]
