Which of the following is a true statement regarding the quadratic formula form of the solutions to a quadratic equation?
The solutions x=4±85√2 must be left in exact form.
The solutions x=4±85√2 are in simplest form.
The solutions x=4±85√2 can be simplified to x=2±45√.
The solutions x=4±85√2 can be simplified to x=2±85√.
Answer:
The solutions x=4±85√2 must be left in exact form.
Step-by-step explanation:
The quadratic formula -b ±√b^2- 4ac/2a will always give us solutions in the form; m±n√q, where m,n and q are integers.
These solutions must always be presented in its exact form, that is, with the square roots in it. Hence the solutions x=4±85√2 are in its exact form.
Why is the product of a rational number and an irrational number irrational?
Answer:
Step-by-step explanation:
When you multiply and irrational by a rational, you are doing nothing to change the nature of an irrational number. The two numbers have different kinds of properties and though a multiplication can be indicated, there is no way you can change the properties of an irrational number with a rational.
Their properties just do not mix.
It is like take a solvent and mixing it with something that is not a solvent. You cannot do anything to anything to the insolvent to make it solvent simply by adding more. Their properties remain in tact.
Take 3 * 4√7
The properties of the 3 and 4 remain the same when multiplied and they can be combined. 3*4 = 12
But nothing can be done with √7. The 3 cannot effect it, anymore than what the 4 did.
Answer:
A. because the product is always a non-terminating, non-repeating decimal.

Find all numbers c [4,12] for which the derivative is equal to the slope of the secant line connecting the function endpoints. If there is more than one such number c, use a comma to separate your answers. Round to the nearest thousandth. If there is no such number c, type "does not exist" in the entry box.
Answer:
Step-by-step explanation:
[tex]f'(x) =\frac{1}{2\sqrt{x-3}}[/tex]
By MVT, there exist a number c on [4, 12] such that
[tex]f'(c) = \frac{f(12)-f(4)}{12-4}[/tex]
[tex]f(12) = 3, and, f(4) = 1, hence f'(c) = \frac{1}{4}[/tex]
therefore,
[tex]\frac{1}{2\sqrt{x-3}} = \frac{1}{4}[/tex]
Solve this equation, you have x =1.
However, this is out of the given interval. Hence does not exist

Amy was looking at a table of conversions from meters to kilometers. The table showed that 2 kilometers are equivalent to 2,000 meters, How can she determine how many kilometers are equivalent to 8,000 meters? Explain.
Answer:
The answer is in the question! If 2km = 2000m then 8km = 8000m
Step-by-step explanation:
Answer:
Sample Response: Amy can multiply 2 by 4, because the number of meters was multiplied by 4 to get 8,000 meters. 1 kilometer is a 1,000 times bigger than 1 meter. She could also divide 8,000 by 1,000 to get 8 kilometers.

What is the surface area of a cube with a side length of > ? inche ?
Greetings from Brasil...
The area of a square is given by the expression: A = L² (where L is the side length)
A cube has 6 sides and each side is a square. So the surface area of a cube will be 6x the area of a square of this cube.
Acube = 6L²You start at (4, -3). You move right 1 unit and left 3 units. Where do you end ?
Answer:
(2, -3)
Step-by-step explanation:
Moving right increases the x-coordinate so after moving 1 unit to the right, we will be at (4 + 1, -3) = (5, -3). Moving left decreases the x-coordinate so after moving 3 units to the left, we will be at (5 - 3, -3) = (2, -3).

help me i need this done in 20 minutes
Answer: 2b + -6
Step-by-step explanation: To simplify, we will use the distributive property.
Before distributing, I would change the -3 to plus a negative 3.
So we have 2(b + -3).
Now, distributing the 2 through the parenthses, we have 2(b) + 2(-3).
2(b) is 2b and 2(-3) is -6.
So we have 2b + -6 as our final answer.
Answer:
2b - 6
Step-by-step explanation:
2(b-3)=

Graph the following function by hand by completing the table
g(x) = (x - 5)² – 3
We know that y - x^2 is a parabola with a vertex at (0, 0).
So if we move it 5 units to the right and 3 units down, the vertex is at (5, -3).
Since it gives you a chart, you can plug in values for x and solve for g(x), and you will eventually get a graph that looks like a parabola with vertex at (5, -3).

Jocelyn makes x dollars per hour working at the grocery store and n dollars per hour babysitting. A. Write an expression that describes her earnings if she babysat for 25 hours and worked at the grocery store for 15 hours. 25n+15x B. How much money did she earn if she charged $10 an hour for babysitting and earned $7.25 an hour at the grocery store.
Answer:
A. 25n + 15x
B. $358.75
Step-by-step explanation:
Jocelyn earns
Grocery store= $x per hour
Babysitting= $n per hour
A. Write an expression that describes her earnings if she babysat for 25 hours and worked at the grocery store for 15 hours.
The expression is:
25n + 15x
B. How much money did she earn if she charged $10 an hour for babysitting and earned $7.25 an hour at the grocery store.
25n + 15x
When n= $10 and x= $7.25
25n + 15x
= 25(10) + 15(7.25)
= 250 + 108.75
= $358.75
Therefore, if Jocelyn earns $10 per hour for babysitting and babysat for 25 hours, and earn $7.5 per hour at the grocery store and works for 15 hours.
Her total earnings will be $358.75

The largest integer value of x that satisfies this inequality is x = 13 so we know that our answer will be 13.
Somebody help me solve what is in the image
Answer:
√2 is approximately 1.4.
Step-by-step explanation:
Part E:
1.3 squared is 1.69.
1.4 squared is 1.96.
1.5 squared is 2.25.
√2 is not between 1.3 and 1.4 because 1.4 squared only reaches up to 1.96 and not 2.
√2 is between 1.4 and 1.5 because 1.4 squared is 1.96 while 1.5 squared is 2.25. The √2 will be somewhere between 1.4 between 1.5.
2 is closer to 1.96 (0.04 units) than 2.25 (0.25 units). Thus, √2 is approximately 1.4.

Find the perimeter of the diagram.
Answer:
D. 52cm
Step-by-step explanation:
The perimeter of a shape is the sum of all its sides.
Not all of the sides are labelled in the diagram. We are missing two sides which I labelled "x" and "y" in the photo below.
We assume all sides are either parallel or perpendicular to each other since they look mostly "straight".
Find the length of the side x:
This side is like the 14cm side, except it's shorter by 3cm at the top and 3cm at the bottom.
x = 14cm - 3cm - 3cm
x = 8cm
Find the length of the side y:
This side is the same length as the 7cm side already labelled at the top.
y = 7cm
Find the perimeter:
Add all of the sides together.
P = 14cm + 7cm + 7cm + 3cm + 3cm + 5cm + 5cm + 8cm
If you want, you can simplify to this equation since some numbers are repeated.
P = [ 2(7 + 3 + 5) + 14 + 8 ] cm
Either way, you get the same answer.
P = 52 cm

Point F' corresponds to point D. point E'. point F. point E.
Answer:
F' corresponds to point F
Step-by-step explanation:
When a point is the result of some transformation, we often designate that result using the base name of the original, with a prime (') added. In this case, we expect that F' is the transformation of point F.
__
Comment on point naming
Of course, points can be given any name you like. These conventions are adopted to aid in communication about transformations and correspondence between points. It would be unusual--even confusing, but not unreasonable, for point F' to correspond to point D, for example. In the case of certain transformations, point F' may actually be point D.
Answer:
C
Step-by-step explanation:
Point F.
