Answer:
21 and 10.5 respectively
Step-by-step explanation:
Remember circumference of a circle is given as;
C= 2×π×r; r is raduis
r = C / 2×π
=65.98/(2×3.142)= 10.50
D= 2× r = 2× 10.50= 21.0( D represent diameter)
Note π = 3.142 a known constant
A. A square is a special type of parallelogram, so every square is a parallelogram. A. is true.
B. Every parallelogram has two sets of opposite sides parallel, but not all angles are right angles. Only some parallelograms are rectangles, not all. B. is false.
C. A parallelogram with 4 congruent sides is a rhombus. A rhombus is a special type of parallelogram, so every rhombus is a parallelogram. C. is true.
D. A rectangle is a special type of parallelogram, so every rectangle is a parallelogram. D. is true.
Answer:
m=1
Step-by-step explanation:
y2-y1/x2-x1
Add the number and that should be your numbers
A direct variation equation is one that requires y varies directly as x and looks like this in equation form:

where k is the constant of variation. If we solve this for y, we have y = kx, which happens to be a linear function... a line. k here, then, serves as the slope. So what we are given as points on a direct variation function are actually points on a line. The equation for this requires that we find the slope and then rewrite the formula accordingly. First the slope:

Now we need to write the equation by using one of the points' coordinates. I picked the first point that has an x coordinate of -9 and a y coordinate of -3. Fitting those into the slope-intercept form of a line,

which simplifies to
-3 = -3 + b and b = 0. That means that the equation of direct variation is
or just
