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.

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

[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)

[tex]11^2+b^2=13^2[/tex]

[tex]169-121=b^2[/tex]

Line p must be drawn so that it can lie in the same plane as line 1

Line p must be drawn in a way that allows it to lie in the same plane as line l.

In geometry, a plane extends in two dimensions indefinitely. There is no width. In coordinate geometry, a plane can be seen as an example. The positions of points in a plane are determined by their coordinates.

A plane is a flat, two-dimensional surface in mathematics that extends indefinitely. A plane is a two-dimensional analog that can incorporate three dimensions of space, a line, and a point.

Given two planes A and B,

and line l is in plane A,

to draw a line parallel to l,

"Two lines in the same plane, which are equally spaced apart and never cross" are parallel lines.

In order for a new line, p, to lie in the same plane as line l, it must be drawn parallel to line l.

Plane A contains line l.

Thus, plane A is where the line p must be drawn.

Hence option C is correct.

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]

Answer:  B.) y-1 = x-1

Step-by-step explanation:

The normal format for point-slope equations is

(y - b) = m(x - a)   a is the x-value of the given coordinate, b is the y-value and m is the slope

Here, the slope is 1, so it is understood, and 1 always "disappears" when it is a factor

So substituting the values given

(y - 4) = (x - 1)  The parentheses are unnecessary because there is no "m"

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 1/2.

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
