Divide change in the output value by the change in the input value for example in this question the rate on the y=+5 and on the x value it’s +1
notice your "a" and "b" components, to get the distance "c" from the center to either foci and the vertices, of course, are h + a, k and h - a, k
Answer:
22.6 degrees
Step:
The hypotenuse is 13cm using pythagoras theorem.
Now, finding the smallest angle is by using;
SOH
sin = opposite over hypotenuse
Thus, cos^-1 (12/13)
=22.61
and equals to 22.6 (1d.p）
Answer:
A classroom has an area of m ^ 2. In the living room there are 25 tables, of which each occupies an area of p m ^ 2, and 27 shelves, of which each occupies an area of 4p m ^ 2. Write an algebraic expression that represents the area of the classroom that is vacant.
Step-by-step explanation:
Answer:
13 and 5
Step-by-step explanation:
x+y=18
x-y=8
_____
2x=26
x=13
So the first number must be 13
13+y=18
y=5
And the second number must be 5
