Plz help with this question

Vlad [161]

Answer:

We have been given a function and its graph.

$y=4 sin(3t)+2$

The first point should be midline of the given function

We can see the coordinate of the midline which is (-3.14,2) will be the first point.

And second point should be maximum or minimum.

So, there is minimum according to the graph.

The minimum point will be at when $sin3t=-1$

$3t=sin^{-1}(-1)$

$\Rightarrow 3t=-sin^{-1}(1)$

$\Rightarrow 3t=-\frac{\pi}{2}$

$\Rightarrow t=-\frac{\pi}{6}$

$\frac{\pi}{6}=-\frac{1.57}{3}$

So, the minimum point is: $(-\frac{1.57}{3},-2)$

In city A, the temperature rises 9° F from 8am then the temperature drops 8°F from 9am to 10am in city B the temperature drops 1

oksian1 [2.3K]

Answer:

For City A, the expression for temperature change is 9 + (-8)

The amount the temperature changes for City A = 1°F

For City B, the expression for temperature change is -1 + (-3) = -4°F

The amount the temperature changes for City B = -4°F

Step-by-step explanation:

The given information are;

In City A, the temperature rise from 8 am to 9 am = 9°F

In City A, the temperature drop from 9 am to 10 am = 8°F

In City B, the temperature drop from 8 am to 9 am = 1°F

In City B, the temperature drop from 9 am to 10 am = 3°F

The expression for that represents the temperature change from 8 am to 10 am is therefore;

For City A

Temperature change from 8 am to 10 am are

8 am to 9 am = +9°F

9 am to 10 am = -8°F

Sum, change from 8 am to 10 am = 9 + (-8) = 1°F

For City B

Temperature change from 8 am to 10 am are

8 am to 9 am = -1°F

9 am to 10 am = -3°F

Sum, change from 8 am to 10 am = -1 + (-3) = -4°F
