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 :)

Help!! Solve for X round to the nearest 10th

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

simplify the equation

Answers

The first one is correct.
It simplifies to 5/3 x plus 2/3 x which equals 7/3 x. This becomes 2 and 1/3 x.
And 8/3 is 2 and 2/3.
The last 2 answers are wrong because 1/3 times -8 gives a negative number.
Remember that when you multiply by 3/3 you change the form but not the number.

35x = hourly rate( hours worked)

35x + y = $190

y = - 35x = 190

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

Next time rewrite the sentence and translate into an equation.

The customers service charges = one-time fee + hourly rate$ ( hours worked)

190 = y + 35(x) point slope form

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. :)

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.
