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.

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

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:

n = {-1, 7}

Step-by-step explanation:

8n² - 56 = 48n

Subtract 48n from both sides

8n² - 48n - 56 = 0

Divide both sides by 8

n² - 6n - 7 = 0

Factor

alternately use the quadratic equation or complete the square

(n - 7)(n + 1) = 0

n = {-1, 7}

Answer:

C

Step-by-step explanation:

To find the x- intercept let f(x) = 0 , then

3log(x - 5) + 2 = 0 ( subtract 2 from both sides )

3log(x - 5) = - 2 ( divide both sides by 3 )

log(x - 5) = - [tex]\frac{2}{3}[/tex] , then

x - 5 = [tex]10^{-\frac{2}{3} }[/tex] ( add 5 to both sides )

x = [tex]10^{-\frac{2}{3} }[/tex] + 5 → C

[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.

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.

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

[tex]S=\frac{x.h}{2} => 2S=x.h => h=\frac{2S}{x} => h= \frac{2(x^{2}+3x+10) }{x} =\frac{2x^{2} +6x+20}{x}[/tex]

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).
