Taylor Swift wants to find the distance, AB, across a river. She starts at point B and walks along the edge of the river 94 ft and marks point C. Then she walks 76 ft further and marks point D. She turns 90° and walks until her final location and marks point E. Point E, point A, and point C are collinear.

Answers

Answer 1

Answer:

A) Ms. Swift can conclude that hey are similar, because line E,C,A is collinear, and they both are right triangles.

B) 158.3ft

Step-by-step explanation:

A) Having a collinear line makes the triangles similar, and because of their collinear line they are both right triangles.

B) The question tells you DE is 103 ft. You take 76ft and Square it giving you 5776ft You then take 103 and square it giving you 10609ft adding them together gives you 16385ft you take the square root of it and it gives you the hypotenuse of triangle CDE. To get the hypotenuse of triangle ABC you take The expression (AB/DE)=(BC/CD)=(AC/EC) step one (AB/DE)=(94ft/76ft)=AC/DE) step two (103ft/127ft)=(94ft/76ft)=(AC/DE) third step (103ft/127ft)=(94ft/76ft)=(128ft/158.3)

I truly hope this helps! :)

The product of 3 and a number equals the sum of 16 and a number.

Answers

Answer:

The numbers can be either -8,-7,-6, or 6, 7, 8.

n(n−1)(n+1)=16(n−1+n+n+1)

⟹n(n2−1)=16×3n

⟹n(n2−1)n=48nn

⟹(n2−1)−48=48−48

⟹n2−49=0

⟶(n−7)(n+7)=0

n can be 7 or −7 , so the numbers can be either −8,−7,−6

The Earth has a diameter
of 7,917.5 miles. What is
the distance a plane
would have to fly if it
could fly around the entire
equator?

Answers

Answer:

L = 24,873.6 miles

Step-by-step explanation:

Length of the Circumference

Given a circle of radius r, the length of the circumference, or line surrounding the shape is:

[tex]L =2\pi\cdot r[/tex]

The Earth has a diameter of 7,917.5 miles. The radius is half the diameter:

r=7,917.5/2=3,958.75 miles

Assuming a plane flies around the equator at ground level, the distance it would travel is:

[tex]L =2\pi\cdot 3,958.75\ miles[/tex]

L = 24,873.6 miles

Solve the simultaneous equations
x + 5y = 16
x + 3y = 10

Answers

Answer: x=1 and y=3

Step-by-step explanation: hope this help

The solution of the linear equations x + 5y = 16 and x + 3y = 10 will be (1, 3).

What is the solution to the equation?

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

The linear equations are given below.

x + 5y = 16 ...1

x + 3y = 10 ...2

Subtract equation 2 from equation 1, then we have

x + 5y - x - 3y = 16 - 10

2y = 6

y = 3

Then the value of the variable 'x' will be given as,

x + 5(3) = 16

x + 15 = 16

x = 1

The solution of the linear equations x + 5y = 16 and x + 3y = 10 will be (1, 3).

Answers

Answer:You can use the concept of conservation of total mechanical energy (neglecting the air resistance).

So, initially total mechanical energy = gravitational potential energy (kinetic energy is zero because initially there is no velocity).

Final total mechanical energy = kinetic energy (gravitational potential energy is zero because height has become zero).

So, initial mechanical energy = Final mechanical energy

25 points What is the equation for the line in slope-intercept form

Answers

Answer:

y=8x

Step-by-step explanation:

x=1 y= 8

x=2 y=16

8=m+b

16=2m+b

m=8

y=8x

Choose 2 coordinates from the line. Let’s pick (0,0) and (2,16)

The equation of a line is on the form y = mx + b where m is the slope and b is the y-intercept.

First let’s find the slope:

m = (y2-y1)/(x2-x1) = (16-0)/(2-0) = 16/2= 8

So we have y = 8x + b

We substitue one of the coordinates to find b. Let’s substitute (0,0)

We get 0 = 0 + b. So b = 0

The equation of the line is y = 8x
