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:

Answer is choice C. We distribute the outer 2 into each of the inner terms (x and -4). Choice D is a trick answer because a lot of the time you might forget to multiply the 2 by the -4 inside the parenthesis (common mistake).

2 times x = 2x

2 times -4 = -8

2 times (x-4) = 2x-8

Side Note: Another path to solve this equation is to divide both sides by 2, then to add 4 to both sides.

[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: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:

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

[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]

[tex]48=b^2[/tex]

[tex]\sqrt{48} =b[/tex]

Use the Pythagorean Theorem Again for sides 9, x, and height which is [tex]\sqrt{48}[/tex]

[tex]x^2+\sqrt{48}^2=9^2[/tex]

([tex]\sqrt{48}^{2}[/tex] is [tex]48[/tex]

[tex]81-48=x^2[/tex]

[tex]33=x^2[/tex]

[tex]x=\sqrt{33}[/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:

The correct expression = 4 / 1/5

The number of rows = 20 rows

Step-by-step explanation:

1/5 Packets of C = 1 row

4 packets of C = x

Cross Multiply

1/5 × x = 4 × 1

The correct expression is

x = 4/ 1/5

x = 4 ÷ 1/5

x = 4 × 5

x = 20 rows

The number of rows Ryan can plant is 20 rows.

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"
