Answer:
- 240
Step-by-step explanation:
We have to find the value of the following determinant
Now, we know that the value of a general determinant 
is given by [a( ei - fh) + b(fg - di) + c(dh - eg)]
Therefore, the value of the given determinant is
= 4[0 × 4 - (-1)(-2)] + 8[3(-1) - 4 × 4] + 10[4(-2) - 3 × 0]
= - 8 - 152 - 80 = - 240 (Answer)
Answer:
w = 10
Step-by-step explanation:
First we take the two values for the breadth of the rectangle
So:
5x - 9 = 3x + 7
now we solve this equation as follows:
5x - 3x = 9 + 7
2x = 16
x = 8
now that we have found the value for x, we can substitute it in the equation, 5x - 9,or in the equation, 3x + 7.
when we substitute x in any of these equations, we get
5(8) - 9 = 31
3(8) + 7 = 31
now that we have the value for the breadth we can form the following equation:
31 × w = 310
31w = 310
w = 310/31 = 10
The complete question is:
Which statements describe the location of an earthquakes epicenter? Check all that apply.
1) it is measured by a seismograph
2) is is located using a single set of data
3) it is determined by the arrival times of s and p waves
4) it is determined by the arrival time of surface waves
5) it is located at the point where circles intersect on a map
Answer:
The answers are; 1, 3 and 5.
Step-by-step explanation:
A Seismograph is a combination of centimeters with a timing device and a recording device. It is used to locate and characterize earthquakes, and to study the Earth's internal structure.
Seismograph are not enough to locate the epicenter through Triangulization. The epicenter can also be extrapolated by using an extrapolation map that deduces the distance to epicenter using the difference in time between the arrival of the s and p waves of the earthquake.
Factor out 7y
7y(y^2 + 3y + 2)
7y(y + 1)(y + 2)
