<h3><u>The first number, x, is equal to 33.</u></h3><h3><u>The second number, y, is equal to 23.</u></h3><h3><u>The third number, z, is equal to 46.</u></h3>

x + y + z = 102

z = 2y

x = 10 + y

Because we have values of x and z, we can plug them into the original equation to solve for y.

10 + y + y + 2y = 102

Combine like terms.

4y + 10 = 102

Subtract 10 from both sides.

4y = 92

Divide both sides by 4.

y = 23

Now that we have a value for y, we can find the value of x and z.

z = 2(23)

z = 46

x = 10 + 23

x = 33

Which is equivalent sin^-1 (cos(pi/2))?Give your answer in radians

NNADVOKAT [17]

Answer:

Given the expression: $\sin^{-1}(\cos(\frac{\pi}{2}))$

Let the value of the given expression in radians be $\theta$

then;

$\sin^{-1}(\cos(\frac{\pi}{2})) =\theta$

$\cos \frac{\pi}{2} = \sin \theta$ ......[1]

We know the value of $\cos \frac{\pi}{2} = 0$

Substitute the given value in [1] we have;

$\sin \theta = 0$

Since, the value of $\sin \theta$ is 0, therefore, the value of $\theta$ is in the form of:

$\theta = n\pi$ ; where n is the integer.

At n =0, 1 and 2, {Since, n is the integer}

Value of $\theta =0, \pi$ and $2\pi$

therefore, the answer in radians either $0 , \pi$ or $2\pi$

The graph of the function g(x)= x^2+3x-4 is shifted 5 units to the left

omeli [17]

<h3>THE MID TERM SPLITTING OF THE EQUATION IS :</h3>

${x}^{2} + 3x - 4$

${x}^{2} + 4x - x - 4$

$x(x + 4) - 1(x + 4)$

$x = -4 \: and \: 1$

$x = 1$

now shifted to 5 units left

therefore,

x=-4

What is Cameron's error??????

pogonyaev

Answer

Cameron forgot to do the same thing to the 9. Instead of dividing 3 by 3 and 9 by 3 he only divided 3 by 3.

Step-by-step explanation:

3/7 × 4/9

You can divide the 3 and 9 by 3 so you get 1/7 × 4/3.

Then you do 4 × 1 and 7 × 3.

Correct answer is 4/21
