Step-by-step explanation:

-3+-8.12+-15.9=-27.02

-27.02/3=-9.00666..

mean=-9.006(6 repeating) so around 9

Answer:

C (This is the option from the image that is attached to the question)

Step-by-step explanation:

Start from (2,0) because it is a point on the line, and go up to two (the rise) and left 1 (the run) you get -2/1 (slope = rise/run) which equals to a slope of -2.

Answer:

There are 80 teddy bears in the store.

Step-by-step explanation:

Let the ratio of the number of dolls to the number of teddy bears is 9:3.

Total no of dolls = 240

We need to find the no of teddy bears in the store.

Let D and T are the no of dolls to the no of teddy bears.

So,

[tex]\dfrac{D}{T}=\dfrac{9}{3}\\\\T=\dfrac{3D}{9}\\\\\text{Put D= 240}\\\\T=\dfrac{3\times 240}{9}\\\\T=80[/tex]

So, there are 80 teddy bears in the store.

Answer:

[tex] \frac{HI}{Jk} [/tex]

Step-by-step explanation:

Recall that, when two triangles are said to be similar to each other, it means that their corresponding side lengths are proportional and the ratio of their side lengths are equal.

We are given that ∆HLI ~ ∆JLK which is justified by the SSS similarity theorem, therefore, [tex] \frac{HL}{JL} = \frac{IL}{KL} [/tex]. This ratio will also be equal to the ratio of the corresponding lengths of their third side, that is:

[tex] \frac{HI}{Jk} [/tex]

Answer:

y ≥ 2

x ≥ 3

6x + 8y ≤ 40

Step-by-step explanation:

The inequalities that she would have to graph to determine how many pizzas and wings she could order will be:

From the information given, Cary is having a party and can only afford to spend no more than $40 on food and she wants to order at least 3 pizzas which cost $6 a pie, and at least 2 orders of wings that cost $8 per order. Therefore, the equation that can be graphed based on the equation will be y ≥ 2, x ≥ 3, and 6x + 8y ≤ 40.

Step-by-step explanation:

Answer:When you play every beat (1, 2, 3, 4) on the snare it’s often called “four on the floor”. True four on the floor would seem to be a bass hit on every beat, like in disco, but don’t let that confuse you. It’s the same musical concept.

“Pretty Woman” is a good example of a four on the floor. I don’t know if four on the floor is exactly a style, because I hear it in classic soul, punk and whatever, but it’s definitely an approach. It’s a way to mix it up, maybe adding a little tension or forward motion without turning up the metronome. The Stooges’ “I Wanna Be Your Dog” is a good example of a song that half-way commits to the four on the floor, and the resulting feel is kind of like falling or stumbling

Answer:

ℼ/2.

Step-by-step explanation:

y = cot x have zero for value of x = nπ + π/2

In trigonometry, there are six trigonometric ratios, namely, sine, cosine, tangent, secant, cosecant, and cotangent. These ratios are written as sin, cos, tan, sec, cosec(or csc), and cot in short.

Given equation,

y = cot x

It is given that cot x = 0

cot is zero in the first and the third quadrants.

cot π/2 = 0.

In the first quadrant, x = π/2

In the third quadrant, x = π + π/2 as cot 3π/2 = 0

Thus, the principle solutions are: x = π/2, and 3π/2.

Now,

cot x = cot π/2

Therefore, x = nπ + π/2, where n ∈ Z is the general solution.

Hence, for value of x = nπ + π/2, graph of y = cot x have a zero.

Answer:

The slope is 3

Step-by-step explanation:

m = slope

y2 and y1 = y coordinates

x2 and x1 = x coordinates

m = y2 - y1 / x2 - x1

m = 9 - 6 / 2 - 1

m = 3 / 1

m = 3

Answer:

1) 3.25 units

2) 4.875 seconds

3) 98.3125 units

4) 2.4375 seconds

Step-by-step explanation:

1) The given equation of motion of the soft ball is y = -16·x² + 78·x + 3.25

Where;

y = The height of the softball

x = The time in seconds after it is hit

Therefore, the initial height of the softball is given by the value of y when x = 0 as follows;

y₀ = -16 × 0² + 78 × 0 + 3.25 = 3.25

Therefore, the initial height of the softball is 3.25 units

2) Given that the initial height of the soft ball is 3.25 ft., we have;

y = -16·x² + 78·x + 3.25 = x·(-16·x + 78) + 3.25

Therefore, the times at which the level of the softball is at 3.25 unit height, are;

x = 0 and ((-16·x + 78) = 0 which gives x = -78/(-16) = 4.875) 4.875 seconds

Therefore, from start time x = 0, the softball was in the air for 4.875 seconds

3) Given that the equation of motion of the softball is the equation of a parabola, the maximum height of the ball is given by the x-coordinate value at the top of the curve where the slope is zero as follows;

d(-16·x² + 78·x + 3.25)/dx = -32·x + 78 = 0

x = -78/(-32) = 39/16 = 2⁷/₁₆ = 2.4375 seconds

The maximum height of the softball is therefore;

[tex]y_{max}[/tex]  = -16 × 2.4375² + 78 × 2.4375 + 3.25 = 98.3125

The maximum height of the softball is 98.3125 units

4) From the calculation for the maximum height, the time it took the softball to reach maximum height = 2.4375 seconds
