Hello There! :)

Option B

A function must pass the Vertical line test. Draw a line. If it touches the graph more than once, it's a relation. If it touches the graph once, it's a function.

Hope this helps!

336 divided by 12 using partial quotients

tensa zangetsu [6.8K]

Answer:

The partial quotients are 20 and 8. The quotient is 28.

Step-by-step explanation:

The dividend is 336 and divisor is 12.

Find the easy factors of 12, which are less than 336.

$12\times 10=120$

$12\times 20=240$

$12\times 30=360$

Since 360>336, therefore 30 cannot be a partial quotient.

So, 20 is a partial quotient. Subtract 240 from 336. Apply this process till the dividend become 0.

The remaining dividend is

$336-240=96$

Find the easy factors of 12, which are less than 96.

$12\times 8=96$

The number 8 is a partial quotient.

$96-96=0$

Now the dividend is zero, so the partial quotients are 20 and 8. The quotient is the sum of partial quotients

$20+8=28$

The quotient is 28.

The sum of two number is 6. Twice the first number added to three times the second number is 10. Write a system of equations and

seropon [69]

Answer:

4 and 2 are the required numbers which satisfies the given equations

Step-by-step explanation:

Let the two numbers be x and y

According to the first condition

their is is 6

which is

x + y =6 ........................(i)

Now according to second condition

twice the first number i.e. 2x added to three time the second number i.e. 3y is 10

in form of equation it could be written as

2x + 3y = 10 ........................(ii)

Now from first equation we have

x + y =6

subtracting y from both sides

x = 6 - y .....................(iii)

Now putting this value of x in equation (ii)

equation (ii) is

2x + 3y = 10

Putting the value gives

2(6-y)+3y = 10

opening the brackets

12 - 2y + 3y = 10

12 - y = 10

subtracting 12 from both sides

12 - y -12 = 10 -12

it becomes

- y = -2

multiplying both sides by (-1)

it becomes

(-1)(-y) = (-2) * (-1)

y = 2

Now we got the value of y put it in equation iii which is

x = 6 -y

putting the value

x = 6 - 2

x = 4

So the two numbers are x = 4 and y = 2

Solve the equation for θ, where

elena-s [515]

Answer:

$\dfrac{\pi}{4},\dfrac{3\pi}{4}$

Step-by-step explanation:

$2\sin^2(\theta)=1$

Divide both sides by 2:

$\sin^2(\theta)=\dfrac{1}{2}$

Take the square root of both sides:

$\sin(\theta)=\dfrac{1}{\sqrt{2}}=\dfrac{\sqrt{2}}{2}$

The only two places on the unit circle where the y value of the point is $\dfrac{\sqrt{2}}{2}$ are at:

$\dfrac{\pi}{4},\dfrac{3\pi}{4}$

Hope this helps!
