A man is climbing down from 250 feet high. He jumps 40 feet down and then descends at a
rate of 30 feet per minute. How many minutes did it take him to reach the ground?

Answers

Answer 1

It take him to 7 minutes reach the ground. You can calculate the tangent  height of an object using the distance and angles

What is the height formula?

By multiplying "D * tan (theta)," where "tan" is the tangent of angle theta, you can determine the height of the object of interest. For instance, rounding up, the height is 40 tan 50 = 47.7 metres if theta is 50 degrees and D is 40 metres.

rate of descent=30 feet per minute

Height of climb=250 feet

Since he jumped 40 feet in no time,

hence,

new height=250-40=210

Time taken to reach ground=height/rate of descent

Time taken=210/30

Time taken=7 minutes

A polynomial equation with rational coefficients has the roots 5, sqrt6, 3, -sqrt7. Find two additional roots.

Thank you!

Answers

Given:

A polynomial equation with rational coefficients has the roots   [tex]5, \sqrt{6}, 3, -\sqrt{7}[/tex].

To find:

The two additional roots.

Solution:

According to the irrational root theorem, if [tex]a+\sqrt{b}[/tex] is a root of a polynomial, then [tex]a-\sqrt{b}[/tex] is also the root of that polynomial.

It is given that, [tex]\sqrt{6}\text{ and }-\sqrt{7}[/tex] are roots of a polynomial.

By using irrational root theorem, [tex]-\sqrt{6}\text{ and }\sqrt{7}[/tex] are also the roots of that polynomial.

Therefore, the two additional roots are [tex]-\sqrt{6}\text{ and }\sqrt{7}[/tex].

You're given a side length of 8 centimeters. How many equilateral triangles can you construct using this information

Answers

Answer:

1 equilateral triangle

Step-by-step explanation:

Given

Shape: Equilateral Triangle

Side length = 8cm

Required

Determine the number of triangles

From the question, we understand that the triangle is equilateral and the length of a side is 8cm.

This implies that the length of other sides will also be 8cm.

So, only one triangle can be constructed and their side lengths is 8cm.

Based on the information given, can you determine that the quadrilateral must be a parallelogram? Explain

Answers

The properties of a parallelogram:

1. opposite sides are parallel

2. opposite sides are equal in length

3. opposite angles are equal

4. diagonals bisect each other

if XN=NZ and NY=NW, then

XY=WZ and XW=YZ because the corresponding angles are equal = corresponding sides are equal

The opposite sides are parallel as well because the diagonals are equal (the vertical opposite angles are equal)

This was a word pasta but hope this helps

The opposite sides are parallel because the diagonals are equal.

Properties of parallelogram

From the given parallelogram, you can see that the diagonals bisect each other.

Also if XN=NZ and NY=NW, then XY=WZ and XW=YZ show that the corresponding angles are equal

Also from the diagram, the opposite sides are parallel because the diagonals are equal (the vertical opposite angles are equal).

how would i solve this please help

Answers

Answer:

x = -3

Step-by-step explanation:

First let us get the equation of the coordinates

y-y0 = m(x-x0)

Using the coordinates ( - 3, 2 ), ( - 1, 0 )

m = 0-2/-1-(-3)

m = -2/2

m = -1

Substitute m = -1 and (-1, 0) into the formula

y - 0 = -1(x+1)

y = -x-1

f(x) = -x-1

Since f(x) = 2

2 = -x-1

-x = 2+1

-x = 3

x = -3

Hence the value of x is -3

A school custodian discovered a leak in a water pipe. The custodian found that 2,432 fluid ounces of water had leaked out. How many gallons of water is​ this? Use the conversion factor 1 gallon 128 fluid ounces.

Answers

Answer: 19 gallons

Step-by-step explanation:

Conversion factor is 1 gallon is to 128 fluid ounces.

If 2,432 fluid ounces leaked out, to find out the amount of gallons this was, you need to divide the fluid ounces by the number of fluid ounces in a gallon. This is what is done when moving from a smaller unit to a larger one.

= 2,432 / 128

= 19 gallons

Answer:

x = y = 4[tex]\sqrt{2}[/tex]

Step-by-step explanation:

Using the cosine ratio in the right triangle and the exact value

cos45° = [tex]\frac{\sqrt{2} }{2}[/tex]  , then

cos45° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{x}{8}[/tex] ( multiply both sides by 8 )

8 × cos45° = x , then

x = 8 × [tex]\frac{\sqrt{2} }{2}[/tex] = 4[tex]\sqrt{2}[/tex]

The third angle in the triangle = 45° ( sum of angles in triangle )

Then the triangle is isosceles with congruent legs, thus

x = y = 4[tex]\sqrt{2}[/tex]

If ADEF = AJKL, DE = 18, EF = 23, DF = 9x - 23, JL = 7x-11, and JK = 3y - 21, find the
values of x and y.

Answers

Answer:

x = 6

y = 13

Step-by-step explanation:

since DE and JK are congruent, they are both 18

to find 'y':

3y - 21 = 18

3y = 39

y = 13

DF and JL are diagonals that are congruent so:

9x - 23 = 7x - 11

2x = 12

x = 6

X=6 Y=13 values of x and y
