A 32-foot ladder leans against a building. The distance between the bottom of the ladder and the base of the building is
8.5 feet. What is the height, in feet, from the ground to the place on the building that the ladder touches? Round your
answer to the nearest tenth.

Answers

Answer:14

Step-by-step explanation:

happy 5685757

The height at which the ladder touches the building is required.

The height of building where the ladder touches the building is 30.9 feet.

Pythagoras theorem

a = Required height

b = Distance between the bottom of the ladder and the base of the building = 8.5 feet

c = Length of ladder = 32 feet

From the Pythagoras theorem we have

[tex]a^2+b^2=c^2\\\Rightarrow a=\sqrt{c^2-b^2}\\\Rightarrow a=\sqrt{32^2-8.5^2}\\\Rightarrow a=30.9\ \text{feet}[/tex]

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).

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

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

If an object was dropped from a height of 405 Meters,find the time it took for the object to hit the ground​

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

3x+2x=6+4

5x=10

divide both sides by 5

X=2

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
