Answer 1

Hello,

A.i. the circumference of a circle is nothing else but its perimeter which formula is π × diameter = π × 2 × radius

Let π = 22/7 ≈ 3.142857, the egyptian approximation

Then if C is the circumference of the circle i., C = 22/7 × 21 = (22 × 21) / 7 = (22× 7×3 )/7 = 22 ×3 = 66 cm

ii. Applying the same formula for the second circle gives us C = 22/7 × 8 = 176/7 ≈ 25.14 meters, rounded to the nearest hundredth...

Good luck !

Answer 2

Answer:

a) 66cm. b) 50.28cm. or 50 2/7cm.

Step-by-step explanation:

The circumference of a circle is C=2πr or C=πd.

π=22/7

a) C=πd

Plugin the diameter.

C=22/7 x 21

=66cm.

b) C=2πr

Plugin the radius.

C=2 x 22/7 x 8

=50.28cm. or 50 2/7cm.

Hope this helps :)

Answers

Step-by-step explanation:

remember : the sum of all angles in a triangle is always 180 degrees.

the law of sines :

a/sin(A) = b/sin(B) = c/sin(C) with the sides being always opposite of the angles.

so,

the opposite angle of x is

180 - 90 - 58 = 32 degrees.

x/sin(32) = 11/sin(58)

x = 11×sin(32)/sin(58) = 6.873562871...

rounded x = 6.9

Answers

Hello there! :)

First, let’s find the slope.

We can find it using this formula:

m=y2-y1/x2-x1

m=7-6/8-4

m=1/4

So the slope is 1/4.

Now, we can use the point-slope formula:

y-y1=m(x-x1)

y-6=1/4(x-1/4)

Hope it helps. :)

$35 per hours × hours work and you did not used the total cost $190

Next time rewrite the sentence and translate into an equation.

Step-by-step explanation:

The value of y from the given equation is 120.8.

The given equation is 62=y-58.8.

What is an equation?

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

The given equation can be solved as follows

Add 58.8 on both the sides of an equation, that is

62+58.8=y-58.8+58.8

⇒ y=120.8

Hence, the value of y from the given equation is 120.8.

Answer:

1. f(3) = 11

2. f( 1 ) = 6

3. f(-2) = -5

Step-by-step explanation:

Note: I will only work on questions 1 and 2 in order to allow you to practice the techniques provided in this post, as you work on question 3. However, I will provide the correct answer for question 3, as your reference.

In order to evaluate each of the given functions, simply substitute the inputs provided in the function notation, f(x).

1. f(x) = 2x + 5, find f(3).

To evaluate the given linear function, simply substitute x = 3 as an input into the function:

f(3) = 2x + 5

f(3) = 2(3) + 5

f(3) = 6 + 5

f(3) = 11

Therefore, the value of f(x) = 2x + 5 given f(3) is: f(3) = 11.

2. f(x) = x² + 2x + 3, find f(1)

Similar to question 1, substitute x = 1 as the input of the given quadratic function.

f(x) = x² + 2x + 3

f( 1 ) = ( 1 )² + 2( 1 ) + 3

f( 1 ) = 1 + 2 + 3

f( 1 ) = 6

Therefore, the value of f(x) = x² + 2x + 3 given f( 1 ) is f( 1 ) = 6.

3. f(x) = 3x² + 5x - 7, find f (-2)

If evaluated properly, the correct answer is: f(-2) = -5.

Problem: A company wants a program that will calculate the weekly paycheck for an employee based on how many hours they worked. For this company, an employee earns $20 an hour for the first 40 hours that they work. The employee earns overtime, $30 an hour, for each hour they work above 40 hours. Example: If an employee works 60 hours in a week, they would earn $20/hr for the first 40 hours. Then they would earn $30/hr for the 20 hours they worked overtime. Therefore, they earned: ($20/hr * 40hrs) + ($30/hr * 20 hrs) = $800 + $600 = $1400 total.
