Estimate g(14). (Use the midpoint to get the most precise estimate.)
I know how to apply the midpoint theorem, but I don't know where I should start my intervals.
We have that for the Question "I know how to apply the midpoint theorem, but I don't know where I should start my intervals." it can be said that
Where you start your intervals are at the (x,y) co-ordinate of the Reference points
From the question we are told
I know how to apply the midpoint theorem, but I don't know where I should start my intervals.
Generally the equation for the midpoint is mathematically given as
[tex]m=\frac{x1+x2}{2},\frac{y1+y2}{2}[/tex]
Naturally the midpoint of two point is the point in between the reference points where distances from them are equal
Therefore
Midpoints co-ordinates simply considers the co-ordinate of the two main reference points.(x,y)
Hence
Where you start your intervals are at the (x,y) co-ordinate of the Reference points

Complete the square leave your answer in root form. 2x² - 6x - 3 = 0
Answer:
x = 1.5 ± √3.75
Step-by-step explanation:
There are several variations of completing the sqaure.
This is the one I use.
-------------------------------------
2x² - 6x - 3 = 0
add 3 to both sides
2x² - 6x = 3
the x² coefficient must be 1
so divide both sides by 2
x² - 3x = 1.5
use half the x coefficient (-3/2 = -1.5) as the complete the square term
(x - 1.5)² = 1.5 + (-1.5)²
(x - 1.5)² = 1.5 + 2.25
(x - 1.5)² = 3.75
Take the square root of both sides
x - 1.5 = ± √3.75
add 1.5 to both sides
x = 1.5 ± √3.75
Answer:
x = 1.5 + √3.75 ; x = 1.5 - √3.75
Step-by-step explanation:
2x² - 6x -3 = 0
Add 3 to both sides
2x² - 6x = 3
Divide the entire equation by the coefficient of x²
[tex]\dfrac{2x^{2}}{2}-\dfrac{6x}{2}=\dfrac{3}{2}\\[/tex]
x² - 3x = 1.5
Divide the coefficient of x by 2 and then square it and add to both sides.
3/2 = 1.5
1.5² = 2.25
Add 2.25 to both sides
x² - 3x + 2.25 = 1.5+2.25
(x - 1.5)² = 3.75
Take square root,
x - 1.5 = ±√3.75
x = 1.5 ± √3.75

Answer:
1800.
Step-by-step explanation:
If N is the first letter the next 2 letters will be the number of permutations of 2 from 25 = 25!/ (25-2)!
= 600.
If the first number is M or P the number is the same so that makes 1800 possibilities.

Also you have to like multiply all of the numbers or sum.
Answer:
174 m^2
Step-by-step explanation:
9 * 5 = 45
9 * 5 = 45
9 * 3 = 27
9 * 3 = 27
5 * 3 = 15
5 * 3 =15
45+45+27+27+15+15 = 174 m^2
Hope this is helpful.
Answer:
174 m²
Step-by-step explanation:
9 * 5 = 45 (that's the bottom and top areas)
9 * 3 = 27 (that's both the bigger sides areas)
5 * 3 = 15 (that's both the smaller sides areas)
Now you have to double:
45 * 2 = 90
27 * 2 = 54
15 * 2 = 30
Now sum:
90 + 30 + 54 = 174

Aiden receives a pay rise of 15%, which increases their pay to $17,250. Calculate his salary before the increase.
Answer:
$15,000
Step-by-step explanation:
Let P represent Aiden's current pay.
If they receive a pay rise of 15%, that means they receive their original pay plus 15% of that original pay.
P + 0.15P = 17250
1.15P = 17250
P = 17250/1.15 = 15000
His salary before the increase was $15,000.
Answer:
$14662.5
Step-by-step explanation:
Aiden receives a pay rise of 15%
increases their pay to $17,250
15% of $17,250 is $2587.5 therefore $17,250 - $2587.5 is his salary before the increase which is 14662.5 so aiden had $14662.5 before his salary increase

Why is an egg a good model of a cell?
Answer:
The egg which we eat is not a single Ovum (egg cell), but an ovum with a nutrient sack (the yolk) suspended in a nutrient protein broth (the egg white). In fairness, the egg yolk is connected to the ovum, so it could be construed as one cell, but the functioning cell part is microscopic.

Answer:
49/101 minutes
Step-by-step explanation:
Your first part is correct the estimate will be 30 minutes because 5 miles divided by 10 miles per hour = 1/2 hours which is 30 minutes.
To solve the second part you need to use the numbers given first so 4 9/10 divided by 10 1/10. I find it easier to do improper fractions in this type of problem so I will do 49/10 divided by 101/10. Now you have to divide. The steps for dividing fractions are
1)Keep the First Fraction the Same.
2)Flip the second fraction over
3)Change the sign to multiplication
After the steps you will get 49/10*10/101
The denominator of the first fraction and the numerator of the second share a factor so you can cross them out. The factor they share is 10 and both numbers are ten so you can cross them out to one. Now you have 49/1*1/101
Since 49 and 101 don't share any factors you can now multiply. You get 49/101.

Answer:
The answer is irrational.
Step-by-step explanation:
Any whole number +/- an irrational number will be irrational as well. Since [tex]\sqrt{14}[/tex]is irrational (it can't be expressed as a ratio of 2 whole numbers) the answer will also be irrational because you are adding it to 19 (a whole number).
A 4.8 pound box of steaks costs $31.20. What is the cost per pound of steaks?
[tex] \frac{31.20}{4.8} = \\ [/tex]
[tex]6.5[/tex]
Thus the cost of steaks per pound is $ 6.5
Easy peasy....
The cost per pound of steaks is $6.5.
What is division?One type of operation in mathematics is division. We divide the phrases or numbers into the same number of components during this operation.
Given, a 4.8 pound box of steaks costs $31.20.
To find the cost per pound of steak:
We take the division of total cost and total pounds in weight.
That means,
Cost per pound of steaks
= 31.20 / 4.8
= 6.5.
Therefore, the cost is $6.5 per pound of steaks.

sophie drove 189 miles in 7 hours if she continued at the same rate how long would it take to travel 216 miles
Answer:
8 Hours
Step-by-step explanation:
If she drove 189 miles in 7 hours, that means she was driving 27 miles an hour, we find this number by dividing 189 by 7.
To find how long it would take to travel 216 miles, we divide 216 by 27, which gives us 8. Meaning it would take 8 hours to drive 216 miles assuming she goes at the same rate
Answer:
It would take her 8 hours.
Step-by-step explanation:
1. 189 ÷ 7, to determine miles per hour. This equals 27, which means that she drives 27 miles every 1 hour.
2. 216 ÷ 27, to determine how long it would take to travel 216 miles. This equals 8, which means that it takes her 8 hours to drive 216 miles.
