(x + 4)³ is x + 4 cubed

(x + 4)³ + 3x is the sum of x + 4 cubed and 3x

Answer:

D

Step-by-step explanation:

The thing that is being cubed here is the sum of x and 4, not x or 4 individually. After you have taken care of what is in parentheses, you add 3x, which gives the sum of x+4 cubed and 3x. Hope this helps!

Find an equation in standard form for the hyperbola with vertices at (0,plus or minus 6) and asymptotes at y= (plus or minus 3/5
antoniya [11.8K]

Answer:

\frac{(y)^2}{36}-\frac{(x)^2}{100}=1

Step-by-step explanation:

Given:

Vertices of Hyperbola : (0 ± 6) or (0,6) and (0,-6)

and asymptotes at y= (±3/5)x 0r y= 3/5 x and y=-3/5 x

The vertices are of vertical hyperbola. The equation used will be:

\frac{(y-k)^2}{a^2}-\frac{(x-h)^2}{b^2}=1\\

The Center of hyperbola (h,k) =(0,0)

The Distance from vertices to center is a and a = 6 (given)

For equation we have value of h,k and a and need to find value of b

we know,

y= k ± a/b (x-h)

Values of h and k are zero

y= 0 ± a/b (x-0)

y= (± a/b ) x

We are given asymtotes at y= (± 3/5)x which is equal to y= (± a/b ) x

as a = 6 then b= 10 i.e The simplified form of 6/10 is 3/5 so value of b=10

Putting values of a,b,h and k in equation we get,

\frac{(y-0)^2}{(6)^2}-\frac{(x-0)^2}{(10)^2}=1\\\\\frac{(y)^2}{36}-\frac{(x)^2}{100}=1

How to solve transformation problems in math
Molodets [167]
In this section we are going to see how knowledge of some fairly simple graphs can help us graph some more complicated graphs. Collectively the methods we’re going to be looking at in this section are called transformations.

Vertical Shifts
The first transformation we’ll look at is a vertical shift.

Math question answer A B C
Sergeu [11.5K]
1a.
you still have
k=C+273.15
k-C= 273.15 as related equations

b. at C=23
k=23+273.15 = 296.15

c. 25°C in kelvin = 25+273.15 = 298.15
so 300K is greater than 25°C

What is the volume of the regular pyramid below?
daser333 [38]

The volume of the regular pyramid is 128 unit³.

Option D) 128 unit³ is the correct answer.

This question is incomplete, the missing image is uploaded along this answer below.

<h3>What is the volume of the regular pyramid?</h3>

The volume of pyramid is expressed as;

V = ( 1/3 ) × l × w × h

Given that;

  • Length l = 8
  • Width W = 8
  • Height h = 6

We substitute our given values into the equation above.

V = ( 1/3 ) × 8 × 8 × 6

V = 128 unit³

The volume of the regular pyramid is 128 unit³.

Option D) 128 unit³ is the correct answer.
