A. B. C. or D? ​

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:

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

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

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]\sqrt{33}[/tex]

Step-by-step explanation:

Use the Pythagorean Theorem For the Triangle with Sides 11, 13, and Height(blue dashed line)

b=height (blue-dashed line)

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.

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

From the graph, the line is passing through two points (0, 10) and (5, 0)

m=0-10/5-0=-2

From the graph, the x intercept is at 5 on x axis.

Answer:

KM = 4 units

Step-by-step explanation:

Here, we are to determine the numerical length of KM

since point L is on the line segment;

Then;

KM = KL + LM

Thus;

5x + 4 = 5x + 1 + 3x + 3

5x + 4 = 8x + 4

8x - 5x = 4-4

3x = 0

x = 0/3 = 0

From the question;

KM = 5x + 4

Substitute x = 0

Thus we have;

5(0) + 4 = 4

KM = 4 units

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
