Answer:
Esmeralda has enough music left in her playlist for a 30 minute workout
Step-by-step explanation:
we know that
If Esmeralda accidentally deleted 25% of the music, then the percentage of music left in her playlist equals 100%-25%=75%.
Find out how many minutes represent 75% of 40 minutes
Multiply 40 by 0.75
therefore
Esmeralda has enough music left in her playlist for a 30 minute workout
Answer:
b=2
c=-24.01
Step-by-step explanation:
If I understood your question right you need to find the constants b and c in the polynomial:
such that:
In order to get a system of two equations you can find limes when x goes to 4 from the right side or from the left side.
I solved this using a number that is close to 4. When it goes from right I used 4.1 and from left 3.9. This way you get two equations:
When you solve the system you get the answers above.
Answer:
Step-by-step explanation:
In order to find out the resulting matrix, we will have to multiply the identity matric and the scalar 3:
The 3x3 identity matrix is:
Multiplying with scalar 3:
The scalar will be multiplied by each element of the matrix.
Multiplying zeros with scalar 3 will give us zero. So the resulting matrix will be:
So the resultant matrix will be a scalar matrix with 3 at diagonal positions..
