Answers

Answer 1

Weren't there several answer choices?

I notice that 27x^3+64 factors into (3x+4)(9x^2-12x+16). The 2nd factor is the quadratic factor that you wanted.

In general, a^3+b^3 = (a+b)(a^2-ab+b^2).

Answer 2

The solution is that 27x^3+64 factors into (3x+4)(9x^2-12x+16).

The 2nd factor is the quadratic factor that you wanted.

What are Polynomials?

Polynomials are sums of k-xⁿ terms, where k can be any number and n can be any positive integer.

3x+2x-5, for example, is a polynomial.

here, we have,

we know that,

In general, a^3+b^3 = (a+b)(a^2-ab+b^2).

given that,

27x^3+64

now, we have to factorize the given expression.

using the above formula, we get,

27x^3+64

= (3x+4)(9x^2-12x+16)

Hence, The solution is that 27x^3+64 factors into (3x+4)(9x^2-12x+16).

The 2nd factor is the quadratic factor that you wanted.

What size does the radius of a sphere need to be for its volume to be larger than its surface area? HINT! It is less than 10. HINT! It is NOT a whole number. If you can show me a whole number for a radius where the surface area and volume are equal, then any radius bigger than that will have a larger volume.

To get full points you will need to SHOW me formulas for surface area of a sphere, volume of a sphere, and calculations on how you found your answer.
Question 1 options:
The formula for the surface area of a sphere is 4 x pi x radius^2
The formula for the volume of a sphere is 4/3 x pi x radius^3.

Answers

we know that
volume of a sphere=(4/3)*pi*r³----> (r/3)*(4*pi*r²)
and
surface area of sphere=4*pi*r²
so
the volume of a sphere=(r/3)*surface area of sphere
therefore
if r=3
volume of a sphere=(3/3)*surface area of sphere
volume of a sphere=surface area of sphere

if r> 3
the term (r/3) is > 0
so
volume of a sphere > surface area of sphere

if r<3
the term (r/3) is < 0
so
volume of a sphere < surface area of sphere

examples
1) for radius r=3 units
volume of a sphere=(4/3)*pi*3³----> 113.04 unit³
surface area=4*pi*3²----> 113.04 units²
volume is equal to surface area

2) for radius r=10 units
volume of a sphere=(4/3)*pi*10³----> 4186.67 unit³
surface area=4*pi*10²----> 1256 units²
volume is > surface area

3) for radius r=2 units
volume of a sphere=(4/3)*pi*2³----> 33.49 unit³
surface area=4*pi*2²----> 50.24 units²
volume is < surface area

Answers

f(x)=2x+1 and g(x)=x^2-7
(f+g)(x) = 2x + 1 + x^2 - 7
(f+g)(x) = x^2 + 2x - 6

answer
x^2 + 2x - 6

Answer: The correct option is (A) [tex]x^2+2x-6.[/tex]

Step-by-step explanation: We are given the following two functions :

[tex]f(x)=2x+1,\\\\g(x)=x^2-7.[/tex]

We are to find the value of [tex](f+g)(x).[/tex]

We know that

for any two functions p(x) and q(x), we have

Write the equation of the line going through the point (4,6) that is perpendicular to the lie 3x+6y=12

Answers

3x + 6y = 12
6y = - 3x + 12
y = - 1/2x + 2

Since your slope is - 1/2, we take the opposite reciprocal to find the perpendicular slope. Your perpendicular slope is 2.

y = 2x + b

Plug in the point to solve for b and get your final line.

6 = 2(4) + b
6 = 8 + b
6 - 8 = b
- 2 = b

y = 2x - 2 is your perpendicular line

The width of a rectangle is 5 inches less than twice the length. The area of the rectangle is 700 square inches. What is the length of the rectangle?

Answers

To calculate the length of the rectangle we let the length be x in, let width be
(2x-5) inches
The area will be given by:
A=length×width
A=x(2x-5)
but
A=700 in²
thus
700=x(2x-5)
700=2x²-5x
this can be written in quadratic form as:
2x²-5x-700=0
solving the quadratic we get:
x=20 or x=-35/2
since the length cannot be negative then:
x=20 in
thus the width will be:
2*20-5
=40-5=35 inches

Answer: Total area of the given prism is (104 + 16√13) Square inches.

Step-by-step explanation:

By the given diagram,

In the right triangular prism,

The sides of the base ( right triangle ) are 4 inches and 6 inches,

We have to finds : T.A. ( the total area of the prism )

Thus, the total base area of the prism = 2 × ( Area of triangle having base 4 inches and height 6 inches )

= 2× ( 1/2 × 4 × 6 )

= 4 × 6

= 24 square inches,

Let the hypotenuse of the triangles having sides 4 and 6 is x inches, ( shown in the diagram )

Thus, by the given diagram,

[tex]x^2 =4^2+6^2[/tex]

[tex]x^2 = 16 + 36[/tex]

[tex]x^2 = 52[/tex]

[tex]x=2\sqrt{13}[/tex]

Now, the total lateral area of the prism,

= 8×2√13 + 8×4 + 8×6

= 16√13 + 32 + 48

= (16√13 + 80) square inches,

Since, the total area of the given prism (T.A.) = Total base area of the prism(B.A.) + Total lateral area ( L.A.)

= 24 + 16√13 + 80

= (104 + 16√13) Square inches.

Answers

The equation of the line in its generic form is:
y = mx + b
Where,
m = (y2-y1) / (x2-x1)

For (-1, 3) and (0, 1):
We look for the value of m:
m = (1-3) / (0 - (- 1))
m = (- 2) / (0 + 1)
m = -2
We look for the value of b:
1 = m (0) + b
b = 1
The line is:
y = -2x + 1

For (1, 4) and (0, 2):
We look for the value of m:
m = (2-4) / (0-1)
m = (- 2) / (- 1)
m = 2

( Please help me, the year is ending and I'm almost at a failing grade): ) An athlete is running along a circular path that has a diameter of 250 yards. The arc traveled by the athlete is 120 degrees. Using 3.14 for (symbol that looks like two Ts that are connected), how many yards did the athlete run? Round the answer to the nearest yard.

Answers

For this case the arc length is given by:
S = R * theta
Where,
R: radius of the circle
Theta: central angle
Substituting values we have:
S = (250/2) * (120) * (3.14 / 180)
S = 261.6666667 yards
Round to the nearest yard:
S = 262 yards
Answer:
the athlete ran:
S = 262 yards

To find the distance an athlete ran on a circular path with a diameter of 250 yards and an arc length of 120 degrees, calculate the arc length using the radius and angle in radians. The athlete ran approximately 262 yards.

To find the distance the athlete ran around a circular path with a given arc length of 120 degrees and a diameter of 250 yards, first, determine the radius of the circle:

Radius (r) = Diameter / 2 = 250 yards / 2 = 125 yards

Convert 120 degrees to radians: 120 degrees × π / 180 = 2π / 3 radians

Calculate the arc length using the formula: Arc Length = Radius × Angle in radians = 125 yards × 2π / 3 = 250π / 3 ≈ 261.8 yards

Therefore, the athlete ran approximately 262 yards.

Answer:

howler 17 17 0.75

The median of howler monkey is, 17

And, Median of spider monkey is, 14

The mean for the howler monkeys is 17 and the MAD is 0.8571.

The mean for the spider monkeys is 14 and the MAD is 1.1429.

The means-to-MAD ratio is 2.6249.

This means that on average, the number of mean absolute deviations that separate the means is 2.6. This means they are different.

Find the median of data set as;

For howler monkey;

There are 8 number of howler monkey.

Hence, Median is,

= (8/2 + 1)

= 5 th term

= 17

For spider monkey;

There are 8 number of spider monkey.

Hence, Median is,

= (8/2 + 1)

= 5 th term

= 14

To find the mean of the howler monkeys, add all of the data values and divide by 7:

= (15+16+17+17+17+17+18+19)/7

= 119/7

= 17

To find the MAD, subtract each data point from the mean; take the absolute deviation; then average these together:

= (|15-17|+|16-17|+|17-17|+|17-17|+|17-17|+|17-17|+|18-17|+|19-17|)/7

= (2+1+0+0+0+0+1+2)/7

= 6/7

= 0.8571

And, Repeating these processes for the spider monkeys:

Mean:

(12+13+13+14+14+14+16+16)/7

= 98/7

= 14

And, MAD:

= (|12-14|+|13-14|+|13-14|+|14-14|+|14-14|+|14-14|+|16-14|+|16-14|)/7

=(2+1+1+0+0+0+2+2)/7

= 8/7

= 1.1429

To find the means-to-MAD ratio, find the difference in the means and divide it by the larger MAD:

17-14=3;

Hence, We get;

3/1.1429 = 2.6249

→ y + 139 − 139 = 180 − 139 ;

to get:

→ y = 41 degrees:
