Please give me an answer for that equations

Zolol [24]

Answer:

S1: 8 = 11x + 8

S2: 0 = 11x

S3: x = 0

S1: 6x = 2x + 24

S2: 4x = 24

S3: x = 6

Step-by-step explanation:

S1: Add like terms (5x+6x)

S2: Subtract 8 from both sides to get x by itself

S3: divide by 11 (anything that divides/is divided by 0 is 0)

S1: Add 7 to the other side

S2: Subtract 2x to the other side

S3: divide 24 by 4

Find the unknown measures. around lengths to the nearest hundredth and angle measures to the nearest degree.

qaws [65]

Answer:

choice 3)

JK = 3.51

WK = 9.15

∠J = 69°

Step-by-step explanation:

sin 21° = JK/9.8

0.3584 = JK/9.8

cos 21° = WK/9.8

0.9336 = WK/9.8

WK = 9.15

∠J = 90° - 21° = 69°

Four resistors are connected in series such that their total resistance is 50ohm . If the resistance of resistors is 5 ohm , 10o

Katyanochek1 [597]

<h2>Answer:</h2>

$\boxed{R_{4}=20\Omega}$

<h2>Step-by-step explanation:</h2>

If resistors are in series, so the current $I$ is the same in all of them. In this problem we have four resistors. So, we can get a relationship between the Equivalent resistance of series combination and the four resistors as follows:

$R_{eq}=R_{1}+R_{2}+R_{3}+R_{4}$

$R_{eq}$ is the total resistance $50\Omega$ . Moreover:

$R_{1}=5\Omega \\ R_{2}=10\Omega \\ R_{3}=15\Omega$

Therefore:

$50=5+10+15+R_{4} \\ \\ R_{4}=50-(5+10+15) \\ \\ R_{4}=50-30 \\ \\ \boxed{R_{4}=20\Omega}$

What is the domain of f(x) = √x – 4 over the set of real numbers?

nikklg [1K]

Answer:

Step-by-step explanation:

Given the sqrt(x), x $\geq \\$ zero

So, given sqrt(x -4), x -4 $\geq \\$ 0

Now solve for x

x - 4 $\geq \\$ 0

x $\geq \\$ 4
