Find the circumference and area of the circle. Use 3.14 for π. Round to the nearest hundredth if necessary.

Answer:

1. 2

2. 5.2

3. (c * 2) - 3= a

4. ($85 + $35 * h)

Step-by-step explanation:

1. |4−2| (simplified)

= |2|

=2

2. 2a^2 = 5.2

(22)(1.3)

=(4)(1.3)

=5.2

(2.6 - (2*1.3))=

5.2 - (2.6 - 2.6) = 5.2

3. (c * 2) - 3= a

4. ($85 + $35 * h)

Step-by-step explanation:

when you plug in 1 to the denominator, 1 minus 1 becomes 0. a fraction with 0 as the denominator does not exist.

The limit of the function f(x)=[tex]x^{3}-1[/tex]/x-1 as x approaches 1 is 3.

Limit is the value that a function approaches as the value of variable approaches some value. They are essential to calculas and mathematical analysis and are use to define continuity , derivatives and integrals. It can change value of function at different values of x.

We have been given a function f(x)=[tex]x^{3}-1[/tex]/x-1 and we have to find the limit of function.

F(x)=[tex]x^{3} -1[/tex] /(x-1) [[tex]x^{3} -y^{3} =x^{2} +y^{2} +xy[/tex]]

[tex]\lim_{x \to \0}x^{3}-1/x-1[/tex]

[tex]\lim_{x \to \0} (x-1)(x^{2} +1+x)[/tex]/x-1

[tex]\lim_{x \to \0} x^{2} +x+1[/tex]

change limit by putting x=1-h

[tex]\lim_{h \to \0} (1-h)^{2} +1+1-h[/tex]

Put the value of h=0.

=1+1+1

=3

Hence the limit of the function [tex]x^{3}-1/x-1[/tex] is 3.

Answer:

y = 1/7x - 8/7

Step-by-step explanation:

y = 7x+8

x=7y+8

x-8 = 7y

1/7x-8/7 = y

The inverse of the given function f(x) = 7x + 8 is equal to

g(x) = [x - 8] / 7.

A variable y is said to be a function of the independent variable x if there is a relationship between them such that whenever a numerical value is assigned to x, there is a rule that determines a specific value of y.

As per the given data:

We are given a function f(x) and we have to find its inverse.

For finding the inverse of a function, we need to express x in terms of f(x).

7x + 8 = f(x)

7x = f(x) - 8

x = [f(x) - 8] / 7

Let's assume the inverse of f(x) is g(x).

g(x) = [x - 8] / 7

The inverse of the given function f(x) = 7x + 8 is equal to g(x) = [x - 8] / 7.

Hence, The inverse of the given function f(x) = 7x + 8 is equal to

g(x) = [x - 8] / 7.

=============================================================

Explanation

We start in the first row at the very left side. The first two digits are the '2' and '4', and they form the value 24. Since 24 is not in the interval from 00 to 14, this means that the first randomly selected student is not left-handed.

The next two digits are 0 and 0. This forms 00 and represents a left-handed student because now we are between 00 and 14. Make a tally of how many left-handed students you count.

As we keep reading across the row, the next two digits are 0 and 7 and they combine to 07. This is another left handed student. However, the student after that is not left-handed since 59 is not in the range from 00 to 14.

Here's a list of all the values we read from the table, and if they're left handed or not:

There are 3 left-handed people in our sample. The table values were: 00, 07, and 09 in that order from left to right.

So that's why the answer is 3.

If you start at another point in the random-number table, then it may be likely that you'll get a different answer. Also, if you decide to read the table in a different way, then you may likely get a different answer.

Answer:

Yes, the car was speeding. I agree with Nico.

Step-by-step explanation:

When you divide 98 miles by 1.7 hours, the answer is 57.6470588. I agree with Nico because it is okay to round because no matter what, the number before the decimal number (57) will always be a greater number than 55. It is easier to round the number for the equation, so Nico is correct in this situation.

Answer:

12

Step-by-step explanation:

All of the angles in a triangle will sum up to 180. So, if you are given 2 of the angles you can find the missing angle, x, using an algebraic equation. Set up the equation 180-(120+45)=x and solve. This equals 12=x.

Answer:

a) Wel can plant four full roes

b) George can plant five full rows

Step-by-step explanation:

The number of seeds in the packet of seeds Wel and George have, n = 20 seeds each

The length of each row of the garden = 10 yards = 30 feet

The distance between the seeds Wel plants, d = 4 feet

The point at which Wel starts to plant the seeds = 4 feet from the end of the row

The distance between the seeds George plants = 2 yards

The point George starts to plant the seeds = 2 yards from the ends his row

Therefore, we have;

a) The length of each row Wel plants her seeds, l = 10 yd. - 4 ft. = 26 ft.

The number of seeds she plants per row = The whole number part of l/d

l/d =  26 ft./(4 ft./seed) = 6.5 seeds

∴ The number of seeds she plants per row, s = 6 seeds

The number of rows Wels plants her seeds, r = The next whole number of the ratio,  n/s =

n/s = 20/6 = 3.[tex]\overline 3[/tex]

∴ The number of rows Wels plants 4 full rows

Therefore;

Using just her packet of seeds, Wels can plant four rows in the garden

b) The length of each row George plants his seed = 10 yd. - 2 yd. = 8 yd.

The number of seeds he plants per row = 8 yd./row/(2 yd./seed) = 4 seeds/row

The number of rows he plants his seeds = 20 seeds/(4 seeds/row) = 5 rows

The number pf rows George plants his seeds = 5 rows

Using just his packet of seeds, George can plant 5 full rows

Answer:

The area of the semi-circle is 35.8 cm².

Step-by-step explanation:

The length of the arc is given by:

[tex] s = r\theta [/tex]   (1)

Where:

s: is the length of the arc of semi-circle = 15 cm

r: is the radius

θ: is the angle in radians    

Since we need to calculate the area of the semi-circle, the angle is:

[tex] \theta = \frac{360}{2} = 180 = \pi [/tex]  

From equation (1) we can find the radius:

[tex] r = \frac{s}{\theta} = \frac{15}{\pi} [/tex]    

Now, the area of the semi-circle is:              

[tex] A = \frac{\pi r^{2}}{2} = \frac{\pi (\frac{15}{\pi})^{2}}{2} = 35.8 cm^{2} [/tex]

Therefore, the area of the semi-circle is 35.8 cm².

Answer:

Cora

Daniel

Daniel

Step-by-step explanation:

Forming equation for Daniel's saving from the plot:

Slope, m :

m = y2 - y1 / x2 - x1

m = (300 - 150) / (3 - 1)

m = 150 /2

m = 75

Intercept, c ; value of y when, x = 0

c = 75

Daniel's equation :

y = 75x + 75

Initial amout is described by intercept

Cora's intercept = 100

Daniel's intercept = 75

Rate is described by the slope

Daniel = 75

Cora = 65

So, Daniel is saving at a faster rate ; 75 to Cora's 65

Amount after 6 months :

After 6 months

y = 75*6 + 75 = $525

Cora:

y = 65x + 100

y = 65*6 + 100 = $490
