Answer:

68 < d

Step-by-step explanation:

-2 > -d/34

(multiply both sides by 34 here)

-68 > -d

(since you multiply by -1 here, you flip the sign.)

68 < d

Answer:

I think it's 14

The whole number is 13 divided by 1 2/3 closest is 8.

We need to find what the whole number is 13 divided by 1 2/3 closest.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Let the unknown whole number be x.

Here, 1 2/3 can be written as 5/3.

Now, x=13/(5/3)

=13 × 3/5

=39/5 = 7.8

≈8

Therefore, the whole number is 13 divided by 1 2/3 closest is 8.

Step-by-step explanation:

First of all, the formula is

M = ([tex]\frac{xA + xB}{2} , \frac{yA + yB}{2}[/tex])

So, plug in all of your numbers in the fourmula.

m= [tex]\frac{4+8}{2} , \frac{-6+3}{2}[/tex]

Next, you will simply the fraction.

Answer:

9

Step-by-step explanation:

The first thing we shall be doing here is substituting f(x) into g(x).

Mathematically, that would be written as g(f(x))

= 2(4x-3)-1 = 8x -6 -1 = 8x - 7

Now we shall find g(f(2)) by substituting 2 into the expression above.

Mathematically, that would be 8(2) -7 = 16-7 = 9

Answer:

27.27cm²

Step-by-step explanation:

∅=125°  r=5m

A=∅/360×πr²

A=125/360×3.142×5²

A=27.27cm²

Answer:

Sample Response: g(x) rises more steeply than f(x) because the value of a in f(x) is 4, whereas the value of a in g(x) is 16. This means that f(x) is a vertical stretch of the square root function by a factor of 4, while g(x) is a vertical stretch of the square root function by a factor of 16. Both functions will contain the point (0, 0), but f(x) would contain the point (1, 4) and g(x) would contain the point (1, 16), which is a steeper rise from the point (0, 0).

The correct option is;

[tex]8.3 = -0.5 \times \left | x -5 \right | + 9[/tex]

Step-by-step explanation:

The coordinates of the roof are;

Starting point, = (1, 7)

Maximum height = (5, 9)

Maximum range = (9, 7)

The slope of the left portion of the roof = (9 - 7)/(5 - 1) = 0.5

The equation of the left portion of the roof is given as follows;

y - 9 = 0.5 × (x - 5)

y = 0.5 × (x - 5) + 9

The slope of the right portion of the roof = (7 - 9)/(9 - 5) = -0.5

The equation of the right portion of the roof is given as follows;

y - 9 = -0.5 × (x - 5)

y = -0.5 × (x - 5) + 9

However, when x < 5, we have;

[tex]0.5 \times \left | x -5 \right |= -0.5 \times \left | x -5 \right |[/tex]

[tex]\therefore y = 0.5 \times \left | x -5 \right | + 9 = -0.5 \times \left | x -5 \right | + 9 = 0.5 \times \left ( x -5 \right ) + 9[/tex]

When x > 5, we have;

[tex]0.5 \times \left | x -5 \right |> -0.5 \times \left | x -5 \right |[/tex]

[tex]\therefore y = -0.5 \times \left | x -5 \right | + 9 = -0.5 \times \left ( x -5 \right ) + 9[/tex]

Therefore, the equation that applies to both the left and right portion of the roof is [tex]y = -0.5 \times \left | x -5 \right | + 9[/tex]

Which gives the correct option as follows;

[tex]y = 8.3 = -0.5 \times \left | x -5 \right | + 9[/tex]

Step-by-step explanation:

Answer:

Well you have to divide 32 by 9 so the answer is 3.5 repeating

Answer:

Step-by-step explanation:

Caleb = 14x

Sergio = 12y

Sergio's boxes each weighed 10 lb more than Caleb's boxes.

y = x + 10

The equation is

14x + 12y = 354

Substitute y = x + 10

14x + 12(x+10) = 354

14x + 12x + 120 = 354

26x = 354 - 120

26x = 234

Divide both sides by 26

x = 234/26

= 9

x = 9lb

Recall,

y = x + 10

= 9 + 10

y = 19lb

Check:

14x + 12y = 354

14(9) + 12(19)

= 126 + 228

= 354

Answer: 19lb

Divide both sides by -2 (flip the sign if you multiply or divide by a negative number)

q < -2

Answer: See explanation below

Step-by-step explanation:

A conic is a curve obtained as the intersection of the surface of a cone with a plane. The 4 types of conic section are: 1. Hyperbola 2. The Parabola 3. The Ellipse and 4. Circle.

Hyperbola: When the plane cuts the cone at an angle closer to the axis than the side of the cone a hyperbola is formed.

Cones: A cone is a three-dimensional shape that goes in a diagonal directions from a flat base to a point called the apex or vertex. A cone is formed by a set of line segments connecting from the base to the apex.

Parabola: A parabola is the curve formed by the intersection of a plane and a cone, but only when the plane is at the same slope as the side of the cone.

Ellipse: An ellipse is formed by a plane intersecting a cone at an angle to its base. All ellipses have two focal points and a center and a major and minor axis.

Circles: A circle is formed when the plane is parallel to the base of the cone.

*Note: Some of these answers are PLAGIARISED from the internet as I looked these up and copied & pasted some information, so please paraphrase if turning this in.*

Answer:  see below

Step-by-step explanation:

Types of Conics are: Circles, Ellipses, & Hyperbolas.

Here is information about each one:

Circle: Two parabolas facing each other. Distance from the center to the vertices are exactly the same.

(x - h)² + (y - k)² = r²

Ellipse: Two parabolas facing each other. Distance from the center to the vertices are not the same.

(x - h)²/a² + (y - k)²/b² = 1

Example: (x - 1)²/9 + (y - 2)²/25 = 1

Center (h, k) = (1, 2)       a = √9 = 3       b = √25 = 5

Vertices (b > a): (1, 2+5) & (1, 2-5)  ==>  (1, 7) & (1, -3)

Co-vertices:      (1+3, 2) & (1-3, 2)  ==>  (4, 2) & (-2, 2)

Foci (b > a): c = √(25-9) = 4  --> (1, 2+4) & (1, 2-4)  ==>  (1, 6) & (1, -2)

Hyperbola: Two parabolas facing AWAY from each other. Distance from the center to the vertices may or may not be the same.

(x - h)²/a² - (y - k)²/b² = 1          or         (y - k)²/b² -  (x - h)²/a² = 1

               ↓                                                            ↓

opens left and right                                opens up and down

Example: (x - 1)²/9 - (y - 2)²/16 = 1

Center (h, k) = (1, 2)       a = √9 = 3       b = √16 = 4

Vertices (x²-y²): (1+3, 2) & (1-3, 2)  ==>  (4, 2) & (-2, 2)

Foci (x²-y²): c = √(9 + 16) = 5  --> (1+5, 2) & (1-5, 2)  ==>  (6, 2) & (-4, 2)

Asymptotes: m = ± 4/3    through (h, k) = (1, 2)     ==> y = ± 4/3(x - 1) + 2

Answer:

The absolute value inequality is;

[tex]\left | w -450 \right |<15[/tex]

Step-by-step explanation:

The given information are;

The number of words Annika needs to write = 450 words

The absolute deviation of the number of words allowed = 15 words

The variable representing the number of words Annika actually wrote = w

Therefore, we have the absolute value inequality given as follows;

[tex]\left | w -450 \right |<15[/tex], which can be written in statement form as follows;

-15 < w - 450 < 15, or as follows

[tex]\left | w -450 \right |<15 \ in \ statement \ form \ is \ -15 < w - 450 < 15[/tex]
