You have a right triangle here so we are going to use a trig identity to solve for y. Y is the side opposite the angle given to us, and then we also have the hypotenuse. Opposite / hypotenuse tells us that we have to use the sin ratio to find y. $sin(52)=\frac{y}{37}$ .

In order to isolate the y, we will multiply both sides by 37 to get

37sin(52)=y. We can do this on our calculator in degree mode and will get that y = 29.156 inches

What is the difference between the temperatures at 10 a.m. and 3:30 p.m.? Indicate whether the change is an increase or decrease

dsp73

Answer:

Change in temperature = - 3.3 F

The temperature has decreased

Step-by-step explanation:

The complete question is attached below .

As given in the attached image

Temperature at 10 A.M $= 1.2$ degree Fahrenheit

Temperature at 3:30 P.M. $= -2.1$ degree Fahrenheit

Change in temperature

= Temperature at 3:30 p.m - Temperature at 10 a.m

= $- 2.1 - 1.2$

$= - 3.3$ F

The temperature has decreased

Use the points A (4,4) and B(4,-5). Complete the description of segment AB and find its length.

Scrat [10]

Use the points A(4, 4) and B(4, −5)

(1) (a) From two points , we will get a vertical line when 'x' values are same and horizontal line segment when 'y' values are same

Here in A(4, 4) and B(4, −5) , the x values are same so the segment AB is a Vertical . The length is the difference between y values ( 4 -(-5)) = 9

Segment AB is a Vertical segment that is 9 units long.

(2) Describe the image of segment AB under the transformation

(x, y) ----> (x, 2y)

A(4, 4) -----> (4, 8)

and B(4, −5) ---> (4, -10)

'x' values are same so line AB is Vertical. The length is the difference between y values ( 8 -(-10)) = 18

The image of segment AB is a Vertical segment that is 18 units long.

(3) Describe the image of segment AB under the transformation

(x, y) ----> (x + 2, y)

A(4, 4) -----> (6, 4)

and B(4, −5) ---> (6, -5)

'x' values are same so line AB is Vertical. The length is the difference between y values ( 4 -(-5)) = 9

The image of AB is a Vertical segment

2 units to the right of the original segment that is

9 units long.

<h2><u>Part A</u>: He started with 4 miles. </h2>

<u>Explanation Part A</u>: 51.664 = (x((1.2⁷)-1)) / 0.2

<h2>
<u>Part B</u>: The equation is 51.664 = (x(1.2⁷)-1)/0.2</h2>

<u>Explanation</u>: n = 7 and on day 7 he traveled 51.664 so Sn = 51.664.

We get the second part of the equation because each day is increased by 20% so we have r = (1.2x) / x = 1.2

So our top half will be x multiplied by ((1.2)⁷-1) because it's the 7th day and we are increasing by 1.2x - 1.

Our bottom half is 1.2 - 1 which equals 0.2

<h2><u>Part C</u> : 103.83 miles</h2>

<u>Explanation: </u> We now have x which is 4 so we plug x into the equation above and remove the 51.664. We also change the 1.2⁷ to 1.2¹⁰ because it's the 10th day not the 7th.

Our equation now looks like (4(1.2¹⁰)-1) / 0.2 which is equal to 103.83 miles.
