(24)^3=13,824

when you multiply 4^3 with 6^3 you get the same answer of 13,824

Answer:

Answer=D

Step-by-step explanation:

(for powers outside a bracket it splits in the numbers inside the bracket)

(4×6)^3

=([tex]4^{3}[/tex]×[tex]6^{3}[/tex]) as in D

To proof

-if we multiply them first we will get 24 and that to the power of three will equal to 13824.

-if we did as in the answer so,

[tex]4^{3}[/tex]×[tex]6^{3}[/tex]

=64×216

=13824

they are equal to each other 13824=13824 so answer D is correct.

I need help with this problem (THIS IS NOT FROM A TEST)

Answers

Answer:

44.5 degrees.

Step-by-step explanation:

Since these triangles are congruent, their angles are the same.

Therefore, we can set an equation with the 2 labeled angles (which are angles C and F):

2.5x+8=3.5x-7

8=x-7

x=15

We can plug 15 back into one of the equations:

2.5(15)+8 = 45.5

This means angle F is 45.5.

To find out the measure of angle E, recall the fact that the angles in a triangle add up to 180. Since this is a right triangle, and F = 45.5, we can set up an equation and solve for x:

90 + 45.5 + x = 180

135.5 + x = 180

x = 44.5

Therefore, the angle E is 44.5 degrees.

Answer:

44.5

Step-by-step explanation:

These triangles are the same so we know that

2.5x + 8 = 3.5x - 7

Subtract 2.5 x from both sides

8 = x - 7

Add 7 to both sides

15 = x

Substitute x

37.5 +8

45.5

There is a right angle so we must add 45.5 + 90 to get 135.5

Subtract 135.5 from 180 to get

44.5

C is the circumcenter of PQR
PC=3x+7, RC=5x-15 and QC=51-x.
what does RC equal?

Answers

Answer:

[tex] RC = 40 [/tex]

Step-by-step explanation:

Given:

PC = 3x + 7,

RC = 5x - 15,

QC = 51 - x.

Required:

measure of RC

SOLUTION:

Given that C is the circumcenter of ∆PQR, therefore, vertices P, Q, and R are equidistant from C.

So therefore,

[tex] PC = RC = QC [/tex]

Let's find the value of x using:

[tex] PC = RC [/tex]

[tex] 3x + 7 = 5x - 15 [/tex] (substitution)

Collect like terms

[tex] 3x - 5x = -7 - 15 [/tex]

[tex] -2x = -22 [/tex]

Divide both sides by -2

[tex] x = \frac{-22}{-2} [/tex]

[tex] x = 11 [/tex]

Find the measure of RC

[tex] RC = 5x - 15 [/tex]

substitute x = 11 into the equation

[tex] RC = 5(11) - 15 [/tex]

[tex] RC = 55 - 15 [/tex]

[tex] RC = 40 [/tex]

A group of students were discussing whether the relationship on the graph
is a function.

Answers

Answer:

A function is a relationship that maps the elements of a set, the domain, into elements of another set, the range.

The restriction that we have for functions is: The elements on the domain can be mapped into only one element in the range.

Then if:

f(x1) = y1

and

f(x1) = y2

where y1 is different than y2

f(x) is not a function.

Now, in the graph you can see a region where both lines overlap, then for some values of x we have two possible values of y, this means that the graph does not represent a function.

Then:

Ed: He is incorrect because we can have different values in the domain mapped into the same value in the range (like in the case of a line y = b, where we have all the elements in the domain mapped into the same element in the range, b)

Debra: There is something called piecewise functions, that are functions of this type, formed by different pieces.

Alejandro: He is correct.

Antoine: Not because you can write an equation means that the relation is a function. You can write an equation for a circle, but it will not be a function.

MOM: I didnt find a worthwhile destination either. KENNETH: Ive concluded that we should embark on an exhilarating and exciting trip this yearsomething weve never done before. MOM: I dont want to dismiss your idea, Kenneth, but where can find such an awe-inspiring experience? KENNETH: I thought we could hike up Mount Whitneyits the highest peak in California. Because its located on the border of Inyo and Tulare counties, its also relatively close to home. Since were all strong athletes, I think that making the ascent is feasible. JEANNETTE: (to Kenneth) That sounds like an awesome and memorable trip; however, theres one problem with your planI suffer from acrophobia. KENNETH: (with a look of befuddlement) Acro- what? MOM: Acrophobiait means that Jeannette suffers from a fear of heights. The root word phobia, meaning fear of, comes from the Greek word phobos, which means fearing. Acrophobia is one of the most prevalent phobias in the country.KENNETH: (to Jeannette) I recall a few years ago when we traveled on an airplane to Aunt Janices houseyou were enthralled, peering out the window at the scene below.JEANNETTE: I did have a tremendous time on the airplane; however, after that trip, my phobia gradually progressed, and now merely thinking about flying evokes terror and makes me squeamish. For me, riding the elevator to the top floor of a tall building is much like trekking up Mount Everestits a gigantic feat of willpower. MOM: Sometimes the best way to get over a fear is to face it. Perhaps we should try to climb the mountain so that Jeannette can tackle her fear. Do you think it would intolerable for you, Jeannette?JEANNETTE: (with a look of trepidation) I dont believe I would be very excited during the ascent, and I may not reach the apex; yet, I would savor the astonishing panoramic views. But what if I lost my composure and chose not to climb with you? I would be loath to jeopardize your trip. DAD: Jeannette, were a family; we must always support each other. I believe that if youre brave enough to attempt the climb, we should be more than willing to stop if you feel overwhelmed or extremely uneasy. MOM: Just trying is an immeasurable accomplishment! KENNETH: Ill have a wonderful vacation as long as I get to view the noteworthy peak; everything else is secondary to me. Whats your verdict, Jeannette?JEANNETTE: The thought of scaling a gigantic mountain is both scary and exhilarating.
