Tamita is making popcorn balls. She has 18.5 ounces of syrup. The recipe says that each batch of popcorn balls needs 4 ounces of

bija089 [108]

Answer:

4 batches

Step-by-step explanation:

Total syrup made by Tamita = 18.5 ounces

Amount of ounces per batch = 4 ounces

If 1 batch = 4 ounces

x batches = 18.5 ounces

Cross multiply

4 * x = 18.5

x = 18.5/4

x = 4.625

Hence she can only make 4 batches of syrup

Consider the surface z = x 2+4y 2+1. Suppose you are walking on this surface directly above a curve C in the xy-plane, where the

Bess [88]

With $x(t)=\cos t$ and $y(t)=\sin t$ , we have

$z(t)=x(t)^2+4y(t)^2+1$

$z(t)=\cos^2t+4\sin^2t+1$

$z(t)=3\sin^2t+2$

Then $z(t)$ has critical points where

$\dfrac{\mathrm dz}{\mathrm dt}=6\sin t\cos t=3\sin2t=0$

$\implies\sin2t=0\implies2t=n\pi\implies t=\dfrac{n\pi}2$

where $n$ is any integer.

$z(t)$ is increasing wherever $\sin2t>0$ , which happens for

$\dfrac{2n\pi}2$

$\boxed{n\pi$
