The force, F newtons, exerted by a magnet on a metal object is inversely
proportional to the square of the distance d cm.
When d = 2 cm, F= 50 N.
Express F in terms of d.

Answers

Answer 1

Answer:

F = 200/d^2

Step-by-step explanation:

F is inversely proportional to d^2

The equation is;

F = k/d^2

K = F•d^2

so to get k, we substitute the given values

K = 50 * 2^2

K = 50 * 4

K = 200

So we have that;

F * d^2 = 200

F = 200/d^2

Area of rectangle = [tex]\mathbf{x^2-4x}[/tex]

Perimeter of rectangle = [tex]\mathbf{4x-8}[/tex]

Step-by-step explanation:

We are given:

Length of rectangle = x

Width of rectangle = x-4

We are not given if we want to find area of rectangle or perimeter of rectangle.

So, I will be finding both

Area of rectangle

The formula used is: [tex]Area\: of\: rectangle=Length \times Width[/tex]

Putting values and finding area

[tex]Area\: of\: rectangle=Length \times Width\\Area\: of\: rectangle=x \times (x-4)\\Area\: of\: rectangle=x^2-4x[/tex]

So, we get area of rectangle = [tex]\mathbf{x^2-4x}[/tex]

Perimeter of rectangle

The formula used is: [tex]Perimeter \: of\: rectangle=2(Length+ Width)[/tex]

Putting values and finding perimeter

[tex]Perimeter \: of\: rectangle=2(Length+ Width)\\Perimeter \: of\: rectangle=2(x+ x-4)\\Perimeter \: of\: rectangle=2(2x-4)\\Perimeter \: of\: rectangle=4x-8[/tex]

So, we get perimeter of rectangle = [tex]\mathbf{4x-8}[/tex]

Is the function an exponential function?
y=(-2)^x

Answers

Answer:Yes

Step-by-step explanation:

the normal exponential function is ab^x, where a represent the growth( sometimes you don't need this part), b is average rate of growth and x is the number of times we exponate. [tex]-2^{x}[/tex] is a exponetital function because it includes the b and x part. The a part is someetimes used but not always.

function is a relationship between inputs where each input is related to exactly one output.

An exponential function is a function in the form

y = [tex]a^{x}[/tex]

Where a = constant and x = variable.

y = [tex](-2)^{x}[/tex] is an exponential function.

Where -2 is a constant and x is a variable.

What is a function?

function is a relationship between inputs where each input is related to exactly one output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

y = [tex](-2)^{x}[/tex]

An exponential function is a function in the form

y = [tex]a^{x}[/tex]

Where a = constant and x = variable.

Example:

y = [tex]3^{x}[/tex]

y = [tex]5^{x}[/tex]

We see that,

y = [tex](-2)^{x}[/tex]

-2 is a constant

x is a variable

Thus,

y = [tex](-2)^{x}[/tex] is an exponential function.

Where -2 is a constant and x is a variable.

Help needed!! Asapp pleasee:(

Answers

Answer:

7362.49 yards

Step-by-step explanation:

Mauricio has a height of 2 yards

The building has a height of 906 yards from the ground

The height of the building from Mauricio's eye will be : 906 - 2 = 904 yards

The angle of elevation of the top of building from the viewer = 7°

Apply the formula for tangent of an angle where;

Tan ∅ = Opposite side height/Adjacent length

Tan 7° = height of building / viewer distance from base of building

Tan 7° = 904 / viewer distance from base of building

Viewer distance from base of building = 904/Tan 7°

=7362.48917089

What is the answer??

Answers

The answer should be: 13.14

Answer:

13.14

Step-by-step explanation:

First you would solve what is in the parentheses.

0.9 - 0.14 = .76

After that you would solve the exponent

3^2 = 9

Now the equation should look like: 9 · 0.76 + 6.3

Multiply 9 and 0.76 to get: 6.84

6.84 + 6.3 = 13.14

I need to find the missing angle thank you

Answers

Answer:

The missing angles measure is 70 degrees

Step-by-step explanation:

First we must complete the left triangles last measure:

60+65+x=180

x=55

Then we have to make all of those three middle angles equal 180:

55+50+y=180

105+y=180

y=75

Now we add 75 to 35 to the missing angle to get 180:

75+35+z=180

110+z=180

z=70

The missing angles measure is 70 degrees

Answer:

23a) x=-y+9/2

23b) x=1/2 y+3/2

Step-by-step explanation:

23a:

Let's solve for x.

2x+2y=9

Step 1: Add -2y to both sides.

2x+2y+−2y=9+−2y

2x=−2y+9

Step 2: Divide both sides by 2.

2x/2 = -2y+9/2

x = -y+9/2

23b:

Let's solve for x.

2x−y=3

Step 1: Add y to both sides.

2x−y+y=3+y

2x=y+3

Step 2: Divide both sides by 2.

2x/2=y+3/2

x = 1/2 y+3/2

what is the length of side c if side A is 7 and side b is 9 and angle c is 79​

Answers

Answer:

C is approximately 10.3

Step-by-step explanation:

To get the length of c, we use the cosine rule

This is;

The square of the missing side is equal the sum of the squares of the other sides minus 2 multiplied by the product of the two other sides and the cos of the angle facing the missing side

We have this as;

c^2 = 7^2 + 9^2 - 2(7)(9) * Cos 79

c^2 = 49 + 81 - 126 cos 79

c^2 = 130 - 24.042

c^2 = 105.96

c = √105.96

c = 10.29 which is approximately 10.3
