Earthquakes can cause all of the above.

trigger other earthquakes - when there is a large magnitude earthquake it
lead to shake the earth's surface. Thus it can create more earthquakes on the same place or neighboring places.

cause billions of dollars - when there is a large disturbance it can destroy big buildings, homes, etc. Which is basically a billion dollar loss.

cause tsunami - If there is a disturbance in the earth's surface near sea's, etc there is chance of tsunami.

How many gallons of paint will you need in order to paint a wall that is 42 feet wide and 27 feet high if one gallon will cover

GREYUIT [131]

Answer:

42 x27 //// 1134 is the area

Step-by-step explanation:

1134/ 200= 5.67

You have to round up because you can’t get .67 of a paint bucket So you would have to round it out. <em>About 6 buckets.</em>

Hey how do you get from standard form to vertex form?

vlabodo [156]

Explanation:

Conversion of a quadratic equation from standard form to vertex form is done by completing the square method.

Assume the quadratic equation to be $\mathbf{ax^{2}+bx+c=0}$ where x is the variable.

Completing the square method is as follows:

send the constant term to other side of equal $\mathbf{ax^{2}+bx=-c}$
divide the whole equation be coefficient of $\mathbf{x^{2}}$ , this will give $\mathbf{x^{2}+\frac{b}{a}x=- \frac{c}{a}}$
add $\mathbf{(\frac{b}{2a})^{2}}$ to both side of equality $\mathbf{x^{2}+2\times\frac{b}{2a}x+\frac{b}{2a}^{2}=-\frac{c}{a}+\frac{b}{2a}^{2}}$
Make one fraction on the right side and compress the expression on the left side $\mathbf{(x+\frac{b}{2a})^{2}=\frac{b^{2}-4ac}{4a^{2}}}$
rearrange the terms will give the vertex form of standard quadratic equation $\mathbf{a(x+\frac{b}{2a})^{2}-\frac{b^{2}-4ac}{4a}=0}$

Follow the above procedure will give the vertex form.

(NOTE : you must know that $\mathbf{(x+a)^{2}=x^{2}+2ax+a^{2}}$ . Use this equation in transforming the equation from step 3 to step 4)
