Answer:
D) [tex]-\sqrt[3]{x-1}[/tex]
Step-by-step explanation:
-the function is the cube root
-the cube root of zero is zero
- the graph is at 0 when x = 1, thus "x-1" must be part of answer
- the cube root of -8 is -2, at -8 the graph is +2. so the function is negated

What is the value of x in theequation 2.5 (6x - 4) = 10 + 4 (1.5 +0.5 x)?
1/3
1/2
2
13
Answer:
x = 2
Step-by-step explanation:
Let's solve your equation step-by-step.
2.5(6x−4)=10+4(1.5+0.5x)
Step 1: Simplify both sides of the equation.
2.5(6x−4)=10+4(1.5+0.5x)
(2.5)(6x)+(2.5)(−4)=10+(4)(1.5)+(4)(0.5x)(Distribute)
15x+−10=10+6+2x
15x−10=(2x)+(10+6)(Combine Like Terms)
15x−10=2x+16
15x−10=2x+16
Step 2: Subtract 2x from both sides.
15x−10−2x=2x+16−2x
13x−10=16
Step 3: Add 10 to both sides.
13x−10+10=16+10
13x=26
Step 4: Divide both sides by 13.
x=2
What is the diameter of a sphere with a volume of 2171m ^ 3 to the nearest tenth of a meter?
Answer:
Diameter of sphere = 16.06 meter (Approx.)
Step-by-step explanation:
Given:
Volume of sphere = 2,171 cubic meter
Find:
Diameter of sphere
Computation:
Volume of sphere = [4/3]πr³
2171 = [4/3]πr³
πr³ = [3/4][2171]
πr³ = [6513 / 4]
πr³ = 1628.25
(3.14)r³ = 1628.25
r³ = 1628.28 / 3.14
r³ = 518.55
r = 8.03 meter (Approx.)
Diameter of sphere = 2r
Diameter of sphere = 2(8.03)
Diameter of sphere = 16.06 meter (Approx.)

Answer:
B only
Step-by-step explanation:
well to solve this question we can consider factor theorem which states that if a Polynomial f(x) is divided by a monomial x-a then x-a is a factor of f(x) if and only if f(a)=0
and to figure "a " we can consider the following equation:
[tex] \displaystyle x - a = 0[/tex]
substitute the given value of a:
[tex] \displaystyle x - 2= 0[/tex]
therefore,
[tex] \displaystyle x = 2[/tex]
option-1:plugin the value of x to the function A(x):
[tex] \displaystyle A(2) = {2}^{3} + {2}^{2} + 4[/tex]
simplify which yields:
[tex] \displaystyle A(2) = 16[/tex]
since A(2)≠0 x-2 is not a factor of A(x)
option-2:similarly substitute the value of x to the function B(x) which yields:
[tex] \displaystyle B(2) = {2}^{3} - {2}^{} - 6[/tex]
simplify:
[tex] \displaystyle B(2) =0[/tex]
so, B(2)=0 Hence x-2 is a factor of x³-x-6
option-3:substitute the value of x to the function C(x)
[tex] \displaystyle C(2) = {2}^{4} + 3.{2}^{} - 10[/tex]
simplify:
[tex] \displaystyle C(2) =12[/tex]
as C(2)≠0 x-2 is not a factor of C(x)
option-4:likewise plugin the value of x to the function D(x):
[tex] \displaystyle D(2) = {2}^{4} - 2.{2}^{3} - 2[/tex]
simplify and that yields:
[tex] \displaystyle D(2) = - 2[/tex]
therefore,D(2)≠0 hence,x-2 isn't a factor of D(-2)
[tex]\boxed{\large{\bold{\textbf{\textsf{{\color{blue}{Answer}}}}}}:)}[/tex]
The factor
x-2=0x=2we have find the value of x .
Now,
we have to select all the polynomial which has x-2 As a factor.
According to the question,
option A:-[tex]A(x)=x^3+x^2+4\\\\A(2)=(2)^3+(2)^2+4\\\\=8+4+4\\\\16≠0[/tex]
so it is not a factor.Option B:-[tex]B(x)=x^3-x-6\\\\=B(2)=(2)^2-2-6\\\\0=0[/tex]
so it is a factor Option C:-[tex]C(x)=x^4+3x-10\\\\=C(2)=(2)^4+3(2)-10\\\\=16+6-10\\\\12≠0[/tex]
so it is not a factoroption D:-[tex]D(x)=x^4-2x^3-2\\\\D(2)=(2)^4-2(2)^3-2\\\\=16-16-2\\\\-2≠0[/tex]
so it is not a factortherefore:-The option B is correct.

Answer:
(36,25)
Step-by-step explanation:
We want to find where the two lines intersect
We know the x value is about 1/2 way between 30 and 40 and the y value is close to 25
The closest value is (36,25)
Step-by-step explanation: I GOT YOU
The point at which the prices are the same would be at (36, 25)
I know this to be true because that's when the lines touch each other (intersect) on the graph. After 36 minutes go by the cost is 25 dollars for both lines. Also the sides have names, cost on the left, and time on the bottom. And the lines stand for the store prices over time. In summary, just look at the number on the side and bottom and see where the lines intersect.
In triangle ABC, AC=13, BC=84, and AB=85. Find the measure of angle C
Given:
In triangle [tex]ABC, AC=13, BC=84, AB=85[/tex].
To find:
The measure of angle C.
Solution:
Law of Cosines:
[tex]\cos C=\dfrac{a^2+b^2-c^2}{2ab}[/tex]
[tex]\cos C=\dfrac{BC^2+AC^2-AB^2}{2(BC)(AC)}[/tex]
Substituting the given values, we get
[tex]\cos C=\dfrac{(84)^2+(13)^2-(85)^2}{2(84)(13)}[/tex]
[tex]\cos C=\dfrac{7056+169-7225}{2184}[/tex]
[tex]\cos C=\dfrac{0}{2184}[/tex]
[tex]\cos C=0[/tex]
Taking cos inverse on both sides, we get
[tex]C=\cos^{-1}(0)[/tex]
[tex]C=90^\circ[/tex]
Therefore, the measure of angle C is 90 degrees.

What equation reoulte from completing the square and then factoring?
x2 + 4x-5
Answer:
Completing the square: [tex](x^2+4x)-5=0[/tex]
Factored form: [tex](x+5)(x-1)=0[/tex]
Step-by-step explanation:
1.
Completing the square is a method used to rewrite a quadratic equation in vertex form. First one groups the linear and the quadratic terms. Then one will factor out the coefficient of the quadratic term. After doing so, one makes the grouped equation a perfect square trinomial by introducing a term, don't forget to balance the equation. Finally one simplifies the equation. The result is a quadratic equation in vertex form.
The quadratic equation:
[tex]x^2+4x-5=0[/tex]
Group the linear and quadratic terms:
[tex](x^2+4x)-5=0[/tex]
The quadratic term doesn't have a coefficient, so one doesn't need to factor the group. Now, one has to add a term to make the group a perfect square trinomial. Remember to balance the equation:
[tex](x^4+4x-4)-5-4=0[/tex]
Simplify,
[tex](x-2)^2-9=0[/tex]
2.
Factoring a quadratic equation is a method of rewriting a quadratic equation as the product of two linear equations. One splits the constant term up into factors, such that the sum of the factors is equal to the coefficient of the linear term.
[tex]x^2+4x-5=0[/tex]

Complete the Square.
[tex] {x}^{2} - 2x = - 6[/tex]
[tex] {x}^{2} - 2x + 1 = - 5[/tex]
[tex](x - 1) {}^{2} = - 5[/tex]

The formula of the equation of a circle is (x-h)^2 + (y-k)^2 = r^2.
First off, for the radius to be 8, r^2 must be 64 so only a and c are plausible. Now, the coordinates for the centre is at (h, k). So the first one is the answer.

The perimeter of a rectangle is 24cm. If the breadth of the rectangle is 4cm, find the area of the rectangle.
Answer:
hope it helps plz mark me brainlliest..!!
Step-by-step explanation:
Perimeter of rectangle =2× (Length+breadth)----(1)
Given that ,
Breadth of rectangle = 4 cm.
Perimeter of rectangle =24 cm.
Let length of rectangle = y cm.
putting the values of perimeter and Breadth in (1)
24=×(y+4)
⇒24=2y+8
⇒2y=24−8
⇒2y=16
⇒y=16/2
⇒y=8.
Therefore, the length of side rectangle is 8 cm.

Answer:
Step-by-step explanation:
Hello!

breadth of the rectangle is 4cm,
2 breadth = 4*2 => 8 cm
24-8 = 16
L= 16/2 = 8
area:8*4 => 32 cm²
