A = 1/2 bh

A = 1/2 • (6x + 4)(x-7)

Use FOIL to multiply the binomials

A = 1/2 • 6x^2 - 3x - 28

Multiply the (1/2) in

A = 3x^2 - 3/2x - 14

Final answer!

What is the ratio of the intensities of an earthquake PP wave passing through the Earth and detected at two points 19 kmkm and 4

Tamiku [17]

Answer:

The ratio of the intensities is roughly 6:1.

Step-by-step explanation:

The intensity I() of an earthquake wave is given by:

$I = \frac{P}{4\pi d^{2}}$

<em>where P: is the power ans d: is the distance. </em>

Hence, the ratio of the intensities of an earthquake wave passing through the Earth and detected at two points 19 km and 46 km from the source is:

$\frac{I_{1}}{I_{2}} = \frac{P/4\pi d_{1}^{2}}{P/4\pi d_{2}^{2}}$

<em>where I₁ = P/4πd₁², d₁=19 km, I₁ = P/4πd₂² and d₂=46 km </em>

$\frac{I_{1}}{I_{2}} = \frac{d_{2}^{2}}{d_{1}^{2}}$

$\frac{I_{1}}{I_{2}} = \frac{46 km^{2}}{19 km^{2}}$

$\frac{I_{1}}{I_{2}} = 5.9:1$

Therefore, the ratio of the intensities is roughly 6:1.

Help need help on slopes

arsen [322]

Answer:

Y= 5/6x+5

Step-by-step explanation:

Okay same as before

the slope is rise over run

The rise is 5

The run is 6

So 5/6

And since ts rising from left to right its positive

The y-intercept which is the first point the line touches the Y axis is 5

So y=5/6x+5

anzhelika [568]

Answer:

Assuming they bought the same shoes, $82.5

Step-by-step explanation:

80% of Original Shoe price = $82

Divide by 0.8 to find the original price.

82 / 0.8 = 102.5

102.5-20=82.5
