which of the following inequalities is graphed on the coordinates plane ?

Answers

Answer 1

Answer:

It Should Be A

Step-by-step explanation:

Answer 2

Answer:

option D.

[tex]y \geqslant 2x + 2[/tex]

Step-by-step explanation:

we have two points on the line

(0, 2)(-1, 0)

using these points to find the equation of the line (shown as red in the figure)

[tex]y - y_{1} = \frac{y _{2} - y _{1} }{x _{2} - x _{1}} (x - x_{1})[/tex]

let,

x₁ = -1 , y₁ = 0x₂ = 0 , y₂ = 2

[tex]y - 0 = \frac{2 - 0}{ 0 + 1} (x + 1) \\ y = 2(x + 1) \\ y = 2x + 2[/tex]

so the equation of the required line (boundary line) is y = 2x+ 2

the shaded portion is represented by inequality :-

[tex]y \geqslant 2x + 2[/tex]

so, option D is the answer

What is the diameter of a sphere with a volume of 72 in”, to the nearest tenth of an
inch?

Answers

The required diameter of the sphere where the volume is 72 inches is 5.2 inches respectively.

What is a sphere?

A sphere is a geometrical object that resembles a two-dimensional circle in three dimensions. In three-dimensional space, a sphere is a collection of points that are all located at the same distance from a single point.

The radius of the sphere is denoted by the letter r, and the specified point represents its center.

The sphere is a three-dimensional shape that is sometimes referred to as a circle's second cousin.

A sphere is a solid shape that is circular, without borders.

Balloons, toy balls, and even light bulbs are examples of objects with sphere shapes.

So, the volume of the sphere formula is:

4/3πr³

We know that the volume is 72 inches.

Then calculate as follows:

72 = 4/3πr³

r³ = 72*3/4π

r = 2.58 (Approx)

Rounding off: 2.6 inches

Then the diameter would be:
2.6 * 2 = 5.2 inches

Therefore, the required diameter of the sphere where the volume is 72 inches is 5.2 inches respectively.

[tex]\lim_{x \to \(-1} f(x)=-2[/tex]

Step-by-step explanation:

In order for a limit to exist in a piecewise function, both its right-side and left-side limits must be equal to each other:

So, if we plug in x=-1 for the left side limit, we get 2cos(πx) = 2cos(π(-1)) = 2cos(-π) = 2(-1) = -2Plugging in x=-1 for the right-side limit, we get 2/cos(πx) = 2/cos(π(-1)) = 2/cos(-π) = 2/(-1) = -2Since both the right-side and left-side limits are equal to each other, we can say that the limit of f(x) as x approaches -1 is -2, therefore the limit existsSee the attached graph

Determine if triangle IJK and triangle LMN are or are not similar, and, if
they are, state how you know. (Note that figures are NOT necessarily drawn to
scale.)

Answers

Yes they are similar! Both share the same angle of 61° then 20x5 is 100 just like 17x5 is 85!!

The triangles are similar, based on the Side-Angle-Side Theorem (SAS).

What is the congruent triangle?

Two triangles are said to be congruent if the length of the sides is equal, a measure of the angles are equal and they can be superimposed.

By definition, since two triangles are similar if the lengths of the corresponding sides are in proportion and their corresponding angles are congruent.

In this case, we can identify that you know two pairs of corresponding sides. Then, we can find in they are in proportion.

Set up that:

In triangle IJK and LMN

Angle JIK = Angle MLN = 61 degree

Notice that they are in proportion.

LN / ML= IK /JI

100 / 20 = 85/ 17 = 5

we can also identify that the corresponding angles L and I are congruent because they have equal measure.

Therefore, since we know that two sides are proportionate and the included angles are congruent, we can conclude that the triangles are similar, based on the Side-Angle-Side Theorem (SAS).

Doug needs to order 25,000 g of a
supplement. At the store,
supplements come in 5 kg packages
that cost $80 each. What will Doug's
order cost?

Answers

Answer:

$2000

Step-by-step explanation:

1,000 g would be = 1 Kg so it would be 25 Kg

And 25 X 80 = 2000

Answer:

$400

Step-by-step explanation:

25,000 grams is equal to 25 kg, so if 5 kg equals $80, the total 25 kg divided by 5 equals five. With this you multiply; 5 × 80 kg = 400. So $400 is the answer.

Find the coordinates of point P along the directed line segment AB so that AP to PB is the given ratio A (4,- 2),B(9, 8); 2 to 3

Answers

Answer:

(7, 4)

Step-by-step explanation:

Using the formula for calculating the midpoint expressed as;

M(X,Y) = {(ax1+bx2)/a+b, ay1+by2/a+b}

X = (ax1+bx2)/a+b

Y = ay1+by2/a+b

Substitute the given coordinate

X = 2(4)+3(9)/2+3

X = 8 + 27/5

X = 35/5

X = 7

Y = 2(-2)+3(8)/2+3

Y = -4+24/5

Y = 20/5

Y = 4

Hence the required coordinates will be at (7, 4)

Determine the slope, the y-intercept and the
x-intercept of the line 4x - 3y - 42 = 0.

Answers

Answer: 3/4

Step-by-step explanation:

First we need to get the formula into slop form (Y = Mx + B) by moving Y to the other side. This can be done by adding 3y to both sides.

4x - 42 = 3y

3y = 4x - 42

Now that we have the formula, we need to divide everything by 3 in order to get 1y.

y = 3/4x - 14

In this formula, M is the slope, meaning your final answer is
