Answer:
Right, 8
Step-by-step explanation:
Edge
Implicit differentiation:
differentiate both sides,
8e^(8x)=cos(x+4y)(1+4y')
Solve for y' to get
y'=[cos(x+4y)-8e^(8x)]/[4cos(x+4y)]
I dont know how to do that but maybe multiply the numbers together
not saying that the right way to do it
Answer:
D = 0
Step-by-step explanation:
Given
x-intercept = -3
Required
What does the discriminant represent?
The discriminant of a quadratic function can take any 3 values; these are as follows;
- When D > 0
- When D < 0
- When D = 0
Which translates to
- signifies that two different real roots exist
- signifies that only complex roots exist
- signifies that the two identical real roots exist
The question says that x-intercept = -3 is the only value;
This means that: x = -3 or x = -3
Analyzing the roots
- 3 and -3 are identical
- -3 and -3 are real
This means they satisfy condition number 3;
Hence, D = 0
6x11÷2
6 x 11 is 66
66 ÷ 2 is 33
The answer is 33
