now, f(0) = 0, and f(-8) is an imaginary value or no real value.
now, f(-10) will also give us an imaginary value
and f(1) = 4
so, doing a first-derivative test on 0, is imaginary to the left and positive on the right, and before and after 1, is positive as well, so f(x) is going up on those intervals.
however, f(0) is 0 and f(1) is higher up, so the absolute maximum will have to be f(1), and we can use f(0) as a minimum, and since it's the only one, the absolute minimum.
the other two, the endpoint of -10 and the critical point of -8, do not yield any values for f(x).

Answer:
The measure of angle CAD is 83 degrees.
Step-by-step explanation:
Given information: ABCD is a parallelogram, AC is a diagonal, 
and 
.
The opposite sides of parallelogram are congruent.
The diagonal AC divides the parallelogram in two congruent triangles.
In triangle ABC and ADC,
(Opposite sides of parallelogram)
(Opposite angles of parallelogram)
(Opposite sides of parallelogram)
By SAS postulate,
Since we know that opposite angles of parallelogram are equal, therefore
According to the angle sum property the sum of interior angles of a triangle is 180 degrees.
Therefore the measure of angle CAD is 83 degrees.
Answer:
x = 2
y = 149
Step-by-step explanation:
these two angles are equal to one another
(8x+15) = (7x+17)
solve for x
x = 2
two angles are supplementary
8x + 15 + y = 180
we know 8x+15 since x =2
8(2) + 15 + y = 180
16 + 15 + y = 180
31 + y = 180
solve for y
y = 180 - 31 = 149
please give brainist, you promised last time :)
Is this talking about mean? Or consecutive numbers in order, like for example, if I had 10, the answer would be 1, 2, 3, 4 because those are consecutive an added up to 10... please explain more if you can<span />
