Answer:

The answer is H = p/mg.

Step-by-step explanation:

Give the variables actual values, and then solve. Let's say:

H = 4

G = 3

M = 2

The equation P = mgh tells us to multiply m x g x h. 3 x 2 x 4 = 24, so P = 24.

Now our values are:

P = 24

H = 4

G = 3

M = 2

So now we have to find which equation is equal to 4, or the value we have substituted for H.

So let's test the answer choices out.

H = P - mg. This would say that 4 = 24 - 2 x 3. 2 x 3 = 6, and 24 - 6 is 18. 18 is not equal to 4, so H = P - mg is not the correct answer.

H = pg/m. This would say that 4 = 24 x 3 divided by 2. 24 x 3 is 72, and 72 divided by 2 is 36. 36 is not equal to 4, so H = pg/m is not the correct answer.

H = P + mg. This would say that 4 = 24 + 2 x 3. 2 x 3 is 6, and 24 + 6 is 30. 30 is not equal to 4, so H = P + mg is not the correct answer.

H = p/mg. This would say that 4 = 24 divided by 2 x 3. 2 x 3 is 6, and 24 divided by 6 is 4. 4 is equal to 4, so H = p/mg is the correct answer.

This formula of substituting the variables for values can work for any value. Just do yourself a favor and make it easy for yourself, by not choosing values like 13045. That's just a waste of time.

Vector b~ has x, y, and z components of 4.4, 9.6, and 5 units, respectively. what is the angle between b~ and the x-axis?
gayaneshka [121]
The simplest vector you can take along the x-axis is \mathbf v=langle1,0,0\rangle.

Now,

\mathbf b\cdot\mathbf v=\|\mathbf b\|\|\mathbf v\|\cos\theta

where \theta is the angle between the two vectors. You have

\mathbf b\cdot\mathbf v=\langle4.4,9.6,5\rangle\cdot\langle1,0,0\rangle=4.4
\|\mathbf b\|=\sqrt{4.4^2+9.6^2+5^2}\approx11.68
\|\mathbf v\|=\sqrt{1^2+0^2+0^2}=1

so that

4.4=11.68\cos\theta\implies\cos\theta=0.3767\implies \theta\approx67.87^\circ

Answer: a) h = 2

              b) a = -\dfrac{3}{4}     k = \bold{3\dfrac{1}{2}}

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

The vertex form of a quadratic equation is: y = a(x - h)² + k     where

  • a is the vertical stretch
  • (h, k) is the vertex

The graph shows the axis of symmetry at x = 2, therefore, the x-coordinate of the vertex (h) is 2.

Two points are given: \bigg(0, \dfrac{1}{2}\bigg)\ and\ \bigg(3, 2 \dfrac{3}{4}\bigg) . We can use these points to create two equations and then solve the system to find the a and k-values.

y = a(x - 2)² + k

\bigg(0, \dfrac{1}{2}\bigg)\\\rightarrow \dfrac{1}{2}=a(0-2)^2+k\\\\\rightarrow \dfrac{1}{2}=4a+k\\\\\rightarrow \dfrac{1}{2}-4a=k\\\\\\\bigg(3, 2\dfrac{3}{4}\bigg)\\\rightarrow 2\dfrac{3}{4}=a(3-2)^2+k\\\\\rightarrow 2\dfrac{3}{4}=a+k\\\\\rightarrow 2\dfrac{3}{4}-a=k\\\\\\\\\dfrac{1}{2}-4a=2\dfrac{3}{4}-a\\\\\dfrac{1}{2}-2\dfrac{3}{4}=4a-a\\\\\dfrac{2}{4}-\dfrac{11}{4}=3a\\\\-\dfrac{9}{4}=3a\\\\-\dfrac{9}{4\cdot 3}=\dfrac{3a}{3}\\\\ \bold{-\dfrac{3}{4}=a}

Solve for k:

2\dfrac{3}{4}-a=k\\\\\\2\dfrac{3}{4}-\bigg(-\dfrac{3}{4}\bigg)=k\\\\\\\bold{3\dfrac{1}{2}=k}
