1.The table provides various values, including all minimums and maximums, of a cosine function f (x) on the interval [0, 2π].

Problem 1

<h3>Answer: D) 2pi</h3>

-------------------

Explanation:

The given table we have is

$\begin{array}{|c|c|c|c|c|c|c|} \cline{1-7}\text{Angle} & 0 & \pi/6 & \pi/2 & 5\pi/6 & 3\pi/2 & 2\pi\\ \cline{1-7}f(x) & 1 & 0 & -1 & 0 & 3 & 1\\ \cline{1-7}\end{array}$

If you were to graph all those points and draw a cosine curve through them, then the function you should get is

$y = 2\cos\left(x+\frac{\pi}{2}\right)+1$

The B coefficient is 1, so that leads to a period of

T = 2pi/B

T = 2pi/1

T = 2pi

=============================================

Problem 2

<h3>Answer: C) 343.134 yards</h3>

-------------------

Explanation:

Draw out a triangle with these properties

side a = 270
side b = 170
angle C = 100

We'll use the law of cosines to find side c

c^2 = a^2 + b^2 - 2*a*b*cos(C)

c^2 = 270^2 + 170^2 - 2*270*170*cos(100)

c^2 = 117740.902710

c = sqrt(117740.902710)

c = 343.133943

c = 343.134

=============================================

Problem 3

<h3>Answer: A) 2</h3>

-------------------

Explanation:

If you started with y = sin(x) and applied the transformations stated, then you should end up with $y = 2\sin\left(2(x+\frac{\pi}{4})\right)\\\\$

From here, plug in x = 0 to find the y intercept.

$y = 2\sin\left(2(x+\frac{\pi}{4})\right)\\\\y = 2\sin\left(2(0+\frac{\pi}{4})\right)\\\\y = 2\sin\left(\frac{\pi}{2}\right)\\\\y = 2*1\\\\y = 2\\\\$

How do you do this? Help me please.

Rufina [12.5K]

Answer:

2800

Step-by-step explanation:

The dress's price increased by a factor of 9/7 so to undo this you flip the numbers around to get 7/9 and multiply the new price by this to get the original price.

2.What is the most precise name for quadrilateral ABCD with vertices A(-2,4), B(5,6), C(12,4), and D(5,2)?

Brums [2.3K]

1) The answer is B, 2) the answer is D, method just put all points and get know the graph of each quadrilateral
3) the measure of one angle in a regular n-gon is given by the following main formula measure of interior angle= (n-2)*180°/n,
so for n=16, we have 14*180°/16=157.5°
4) the answer is A, because 360/5=72 > 40=360/9

Find the area of the parallelogram.

tensa zangetsu [6.8K]

Answer:

Step-by-step explanation:

Area of a parallelogram = base × height

From the question

The base is = 30 cm

Let h represent the height of the parallelogram

We must first use Pythagoras theorem to find the height of the parallelogram before finding it's area

We have

${25}^{2} = {h}^{2} + {24}^{2} \\ {h}^{2} = {25}^{2} - {24}^{2} \\ {h}^{2} = \sqrt{ {25}^{2} - {24}^{2} } \\ {h}^{2} = \sqrt{625 - 576} \\ {h}^{2} = \sqrt{49}$

We have the answer as

h = 7 cm

So from the question

height = 7cm

Let's substitute the base and the height into the above formula and solve for the area

We have

Area = 30 × 7

We have the final answer as

Hope this helps you
