224 I think yea it’s probably it
<span>(x – h)</span>2<span> + (y – k)</span>2<span> = r</span><span>2
h is your x value and the opposite of k is your y value. r is the radius
so, in the first equation, your center would be (-4,2) and the radius would be 5 because you take the square root of r
So plot (-4,2) and count 5 units left, right, up, and down from that point.
Do the same thing for the second circle. The center is (2,-1) and the radius is 5.6 units
The other graphs are pretty much the same way.
For number 7, plot the center and the other set of coordinates. Count the distance between the center and that point and that is your radius
For number 6, plot the center, and to get the radius, take half of the diameter.
For the last one you have to use the distance formula</span>
Step-by-step explanation:
it is proved in above figure
Answer:
650
Step-by-step explanation:
The number of packets of waffles is W
and the number of muffins are M
The weight of dough is 250 pounds and a pack of muffins requires 1 lb of dough whereas a pack of waffles uses 3/4 lb of dough.
3÷4W+M≤250
Multiplying both sides by 4
3W+4M≤1000
It takes bakers 6 minutes to make a packer of waffles and 3 minutes to make a pack of muffins, the total time available is 20 hours or 1200 minutes.
3M+6M≤1200
Minus the initial equation from the new equation:
(3M+6M≤1200)−(3W+4M≤1000)
2M≤200
Dividing equation by 2
M≤100
For M≤100
3W+4M≤1000
3W≤1000−4M
For the Maximum values of M
the least value of W is obtained
3W≥1000−4×100
3W≥600
Dividing the equation by 3
W≥300
For maximum profit, the number of waffles and muffins is taken as 300 and 100 respectively :
1.5∗300+2∗100
=650
