the correct answer is A
need to solve for Y using X =0 and plot all the points
<h3>Given</h3>
- C(t) = 40 cm + t·(2/5 cm/s) . . . circumference of a circle vs time
<h3>Find</h3>
- dr/dt for radius r
- r at t=4 seconds
<h3>Solution</h3>
The circumference and radius of a circle are related by
... C = 2πr
so the radius in terms of circumference is
... r = C/(2π)
... r(t) = (40 +0.4t)/(2π) = (1/π)(20 cm + 0.2t cm/s)
Then dr/dt is
... dr/dt = 0.2/π cm/s
And the radius at t=4 s is
... r(4) = (1/π)(20 + 0.2·4) cm
... r(4) = 20.8/π cm
Answer:
6 servings
Step-by-step explanation:
Each serving Tim uses 1/9 cup. So, after using the amount of syrup reduces and repeated subtraction is division.
÷ 
= 2 *3
= 6
X = 4
Porque:
5(x + 3) = 2x + 3
5x + 15 = 2x + 3
5x - 2x = 3 - 15
- 3x = - 12
x = -12/ -3
x = 4 ✔️
