Find the length of side x in simplest radical form with a rational denominator

Find The Length Of Side X In Simplest Radical Form With A Rational Denominator

Answers

Answer 1

Answer: 4√2

Step-by-step explanation:

The triangle is a special right triangle. Using this, you know that the legs of the triangle are 1 and 1 as the 45, 45, 90 triangle has the sides of 1, 1 and √2. That being said,

4 x 1 = 4 - This is one of your sides

4 x 1 = 4 - This is your other side.

4 x √2 = 4√2 = This your your hypotenuse or your x.

My teacher played me this song to help me remember 45, 45, 90 and 30, 60, 90 triangles. Look up "45 45 90 30 60 90 song" and look for the channel, "Scalar Learning"

I hope this answered your problem.

Jason begins at the start of a path and rides his bike 11 12 miles on the path. The path is 12 14 miles long. Enter the distance, in miles, Jason must ride to reach the end of the path. Show your work.

Answers

Answer:

Number of miles remaining for Jason to reach end of the path = 3/4 miles

Step-by-step explanation:

Total distance of the path = 12 1/4 miles

Distance reached by Jason's bike on the path = 11 1/2 miles

Enter the distance, in miles, Jason must ride to reach the end of the path.

Number of miles remaining for Jason to reach end of the path = Total distance of the path - Distance reached by Jason's bike on the path

= 12 1/4 miles - 11 1/2 miles

= 49/4 - 23/2

= (49-46) / 4

= 3/4 miles

Number of miles remaining for Jason to reach end of the path = 3/4 miles

Below is the entire graph of function f graph f^-1, the inverse of f

Answers

I think:- every point that expresses the graph of the function f must be subtracted 1

The graph of the inverse of a function is its reflection across the line y = x

Please find attached the required graph created with MS Excel

The graph of the inverse of a function is reflected over the line y = x

In order to graph the function f⁻¹, either the line y = x is drawn and the points of f⁻¹ are traced by taking equal distance from the line y = x, or the x, and y-coordinates of the f are reversed to get the coordinates of f⁻¹ as follows;

The reflection of the point (x, y) across the line y = x is (y, x)

The vertices of the graph of the function f, staring from the top are;

(5, 6), (3, -3), (-3, -5)

Therefore, we have;

The reflection of the point (5, 6) across the line y = x is (6, 5)

The reflection of the point (3, -3) across the line y = x is (-3, 3)

The reflection of the point (-3, -5) across the line y = x is (-5, -3)

The graph of the function f⁻¹ can be plotted using MS Excel, and the above values, as shown in the attached diagram

A tree is 15 feet tall and casts a shadow of 9 feet. How long is the shadow of a tree 25 feet tall?

Answers

I’m not sure if this is right but I would try to think of the question as a ratio. 15ft casts a 9ft shadow (15:9). But u want to find out the length of the shadow when the tree is 25ft. The initial ratio can be divided by 3 (5:3) this makes it easier to get the 25ft tree and it’s shadow equivalent. 25/5=5 so a 25ft would cast a 15ft shadow

Answer:15ft shadow

Answer:

The shadow is 15 feet long.

Step-by-step explanation:

This is a proportion question.  Build a proportion using two fractions.

[tex]\frac{\text{tree height}}{\text{shadow length}}[/tex]

[tex]\frac{15}{9}=\frac{25}{x}[/tex]

"Cross-multiply" -- you might know this as the Means-Extremes Property of Proportions.

A(4,10) and B (6,12)
(1) Find the distance between A and B

Answers

Answer:

2.8284

Step-by-step explanation:

Input Data :

Point 1(xA,yA)(xA,yA) = (4, 10)

Point 2(xB,yB)(xB,yB) = (6, 12)

Objective :

Find the distance between two given points on a line?

Formula :

Distance between two points = √(xB−xA)2+(yB−yA)2(xB-xA)2+(yB-yA)2

Solution :

Distance between two points = √(6−4)2+(12−10)2(6-4)2+(12-10)2

= √22+2222+22

= √4+44+4

= √88 = 2.8284

Distance between points (4, 10) and (6, 12) is 2.8284
