Answers
===============================================================
Explanation:
Choice a) can be ruled out because angles A and D are supplementary. Supplementary angles add to 180 degrees by definition. They form a straight line or straight angle.
Choice b) and choice d) are eliminated for similar reasoning as choice a).
Choice c) is the only thing left. It turns out that angles B and D are not supplementary, but rather they are vertical angles. They are opposite one another in this X shape. Vertical angles are always congruent.
Note: Angles B and D are supplementary if and only if the angles are 90 degrees each.

To solve the equation x ^2 - 2x = 3 by the technique of completing the square, you would add 4 to each side of the equation as one of the steps to reaching the solution.
Answers
Answer:
x = -1
x = 3
Step-by-step explanation:
[tex]\sf x^2 - 2x = 3[/tex]
Add 1 to both sides:
[tex]\sf \implies x^2 - 2x+1 = 3+1[/tex]
Factor the left side:
[tex]\sf \implies (x-1)^2 = 4[/tex]
Square root both sides:
[tex]\sf \implies x-1 = \pm2[/tex]
Therefore:
[tex]\sf \implies x-1=-2 \implies x=-1[/tex]
[tex]\sf \implies x-1=2 \implies x=3[/tex]

Infinite solutionsGiven f(x)= 2x^3+kx-1, and x+1 is a factor of f(x), then what is the value of k?
Answers
Answer:
put x=-1, and the rest will be easy
If x + 1 divides f(x), this means x = -1 is a root of f(x), i.e. f(-1) = 0. Plugging in x = -1 gives
f(-1) = 2 (-1)³ + k (-1) - 1 = -3 - k = 0
Solve for k; you end up with k = -3.

I need help please with this 1 problem
Answers
Answer:
See below, please
Step-by-step explanation:
We know
[tex]f(x) = {x}^{2} + 3x - 7[/tex]
[tex]g(x) = 3x + 5[/tex]
[tex]h(x) = 2 {x}^{2} - 4[/tex]
Hence
[tex]f(g(x))[/tex]
[tex] = {(3x + 5)}^{2} + 3 \times (3x + 5) - 7[/tex]
[tex] = (9 {x}^{2} + 30x + 25) + (9x + 15) - 7[/tex]
[tex] = 9 {x}^{2} + 39x + 33[/tex]
[tex]h(g(x))[/tex]
[tex] = 2 \times {(3x + 5)}^{2} - 4[/tex]
[tex]2 \times (9 {x}^{2} + 30x + 25) - 4[/tex]
[tex] = 18 {x}^{2} + 60x + 50 - 4[/tex]
[tex] = 18 {x}^{2} + 60x + 46[/tex]
[tex](h - f)(x)[/tex]
[tex] = h(x) - f(x)[/tex]
[tex] = (2 {x}^{2} - 4) - ( {x}^{2} + 3x - 7)[/tex]
[tex] = {x}^{2} - 3x + 3[/tex]
[tex](f + g)(x)[/tex]
[tex] = f(x) + g(x)[/tex]
[tex] = ( {x}^{2} + 3x - 7) + (3x + 5)[/tex]
[tex] = {x}^{2} + 6x - 2[/tex]

Sophia has unsharpened pencils that are 20 centimeters long. What is the approximate surface area of a pencil?
Answers
The surface area of the pencil is the amount of space it covers
The surface area of the pencil is 61 square centimeters
How to determine the surface area?The given parameters are:
H = 20 cm
L = 0.5 cm
The surface area (SA) is then calculated as:
SA = 6LH + 3[tex]\sqrt 3[/tex]L^2
This gives
SA = 6 * 0.5 * 20 + 3[tex]\sqrt 3[/tex] * 0.5^2
Evaluate the sum
SA = 61
Hence, the surface area of the pencil is 61 square centimeters

A sollid piece of iron in the form of a cuboid of dimensions 49cm × 33 cm× 24 cm , is moulded to form a solid sphere. find the radius of the sphere
Answers
Answer:
Radius of sphere is 21 cmStep-by-step explanation:
Given:
A sollid piece of iron in the form of a cuboid of dimensions 49cm × 33 cm× 24 cm , is moulded to form a solid sphere.To Find:
Radius of the sphereSolution:
Volume of sphere = Volume of cubiod
↠ 4/3 πr³ = LBH
↠ 4/3 × 22/7 × r³ = 49 × 33 × 24
↠ 4/3 × 22/7 × r³ = 38808
↠ 4 × 22/7 × r³ = 38808/3
↠ r³ = 38808 × 3 × 7/4 × 22
↠ r³ = 441 × 21
↠ r³ = 9261
↠ r = 21 cm
Hence,
Radius of sphere is 21 cmAnswer:
21.00 cm to the nearest hundredth.
Step-by-step explanation:
The volume of the sphere will be equal to the volume of the cuboid.
So 4/3 π r^3 = 49*33*24 where r = radius of the sphere.
r^3 = (49*33*24 ) / 4/3 π
r^3 = 38808 / 4.18879
= 9264.728
r = ∛9264.728
= 21.0028 cm.

A perpendicular line is always the negative reciprocal of the slope. In this case, the slope is 4/5. Therefore, the negative reciprocal is -5/4. Only look at the numbers connected to X for the slope, do not look at the constant.
