Answer:
a = -21 and b = 15
Step-by-step explanation:
It is given a matrix multiplication,
<u>To find the value of a and b
</u>
It is given that,
| 6 -5 | * | -1 | = | a |
|-3 4 | | 3 | | b |
We can write,
a = (6 * -1) + (-5 * 3)
= -6 + -15
= -2
1
b = (-3 * -1) + (4 * 3)
= 3 + 12
= 215
Therefore the value of a = -21 and b = 15
The magnitude of an earthquake that is 35 more times intense than a standard earthquake is 1.5
Step-by-step explanation:
Let
I be the intensity for which we have to find magnitude
S is the standard intensity of earthquake
And
M is the magnitude
The intensity of standard earthquake is 10.
The formula for magnitude is:
The magnitude of an earthquake that is 35 more times intense than a standard earthquake is 1.5

Let x be the number of hours she jogs, and y be the number of hours she bikes.
The total time would then be x + y = 5
The total distance (based on the given speeds) would be 6x + 12y = 50
Multiply the first equation by 6 to get 6x + 6y = 30
Subtract this from the second equation to get 6y = 20
y = 10/3 or 3 1/3
Substitute this value back into the first equation to get x = 5/3 or 1 2/3
Therefore, Yolanda will have to jog 1 2/3 hours and bike 3 1/3 hours.
