Maria throws a softball straight up into the air with an initial velocity of 50 ft/sec. The ball leaves her hand when it is exactly 4 ft. Above the ground. Write an equation that models the situation.
Answer:
The equation that models the situation is [tex]s_{f} = 4+\frac{v_{f}^{2}-2500}{64.348}[/tex].
Step-by-step explanation:
Let suppose that effects from air friction and Earth's rotation can be neglected, so that the softball can be modelled experiment a free fall, that is, an uniform accelerated motion due to gravity. From we know the initial velocity and position of the position and we can determine the final position of the ball as a function of the final velocity:
[tex]v_{f}^{2} = v_{o}^{2}+2\cdot a \cdot (s_{f}-s_{o})[/tex] (1)
Where:
[tex]s_{o}[/tex], [tex]s_{f}[/tex] - Initial and final position of the softball, measured in feet.
[tex]a[/tex] - Acceleration, measured in meters per square second.
[tex]v_{o}[/tex], [tex]v_{f}[/tex] - Initial and final velocities of the softball, measured in feet per second.
If we know that [tex]v_{o} = 50\,\frac{ft}{s}[/tex], [tex]a = -32.174\,\frac{m}{s^{2}}[/tex] and [tex]s_{o} = 4\,ft[/tex], then the equation that models the situation is:
[tex]v_{f}^{2} = 2500-64.348\cdot (s_{f}-4)[/tex]
Then, we clear the final position of the softball:
[tex]-\frac{v_{f}^{2}-2500}{-64.348} = s_{f}-4[/tex]
[tex]s_{f} = 4+\frac{v_{f}^{2}-2500}{64.348}[/tex]
The equation that models the situation is [tex]s_{f} = 4+\frac{v_{f}^{2}-2500}{64.348}[/tex].

Barb is making a bead necklace. She strings 1 white bead, 3 blue bead, then 1 white bead, and so on. Write the numbers for the the eight beads that are white. What is the rule for the pattern?
Answer:
1,5,9,13,17,21,25,29
Step-by-step explanation:
From the information given.
Let represent the number of white beads with x and the number of blue beads with y. So, the beads can be illustrated as:
bead color
1 x
2 y
3 y
4 y
5 x
6 y
7 y
8 y
Suppose n denotes the no. of beads that are white.
Then the subsequent no is ( n + 4).
Since the first number n = 1
Then the subsequent numbers will follow the pattern of adding 4 to the number.
i.e.
n = 1 + 4 = 5
n = 5 + 4 = 9
n = 9 + 4 = 13
n = 13 + 4 =1 7
n = 17 + 4 = 21
n = 21 + 4 = 25
n = 25 + 4 = 29
Thus, the number for the first eight beads that are white are:
1,5,9,13,17,21,25,29
The pattern shows odd numbers only.

Latoya needs to make a total of deliveries this week. So far she has completed of them. What percentage of her total deliveries has Latoya completed?
Answer: 35%
Step-by-step explanation:
You did not give the numbers. Let me help out by giving some figures and explain with that.
Latoya needs to make a total of 60 deliveries this week. So far she has completed 21 of them. What percentage of her total deliveries has Latoya completed?
To solve this, we divide 21 by 60 and then multiply by 100. This will be:
= (21 / 60) × 100
= 7/20 × 100
= 35%

Answer:
k = 1
Step-by-step explanation:
so we basically have to solve for k
13 = 4k + 9
subtract 9 from both sides
4 = 4k
divide both sides by 4 to get k by itself
4/4 = 1
4k / 4 = 1k = k
1 = k

which of the following recursive formulas represents the same arithmetic sequence as the explicit formula an= -2 + (n-1)3?
Answer: C.[tex]\left \{ {{a1=-2} \atop {an=a(n-1)+3}} \right.[/tex]
because it is the arithmetic progression with d = 3
=> a(n) = a1 + (n - 1).3
so, have: a1 = -2
an = a(n-1) + 3

Tori bought 24 candy bars for 69 cents each. She used partial products to find the total cost in cents. Which are NOT possible partial products for 24 × 69? Choose all that apply. A. 24 B. 36 C. 180 D. 240 E. 1,656
Answer:
B. 36 C. 180 D. 240 E. 1,656
Step-by-step explanation:
Partial product is the multiplication of individual digit of a number in turn with each digit of the others where each digit maintains its place.
Using distributive property to multiply 24 × 69 to determine our partial products:
i.e.
24 × 69 = 24 × (60 + 9)
= (24 × 60) + (24 × 9)
= 60 (20 + 4) + 9(20 + 4)
So; we can have:
= (60 × 20) + (60 × 4) + (9 × 20) + (9 × 4)
= 1200 + 240 + 180 + 36
= 1656

∠A and \angle B∠B are vertical angles. If m\angle A=(5x-2)^{\circ}∠A=(5x−2) ∘ and m\angle B=(3x+12)^{\circ}∠B=(3x+12) ∘ , then find the value of x.
Answer:
x = 7
Step-by-step explanation:
From the above question, we are told that:
∠A and ∠B vertical angles.
It is important to note that vertical angles are equal to each other
Hence:
∠A = ∠B
From the question,
∠A = (5x−2)°
∠B = (3x+12)°
Hence:
(5x−2)°= (3x+12)°
5x - 2 = 3x + 12
Collect like terms
5x - 3x = 12 +2
2x = 14
x = 14/2
x = 7
Answer:
X=14

A cake recipe calls for 1.5 cups of milk and 3 cups of flower. Seth made a mistake and used 5 cups of flour. How many cups of milk should he use to keep the proportions correct?
Answer:
2.5 cups of milk
Step-by-step explanation:
Given that,
A cake recipe calls for 1.5 cups of milk and 3 cups of flower.
Seth made a mistake and used 5 cups of flour.
We need to find number of cups of milk he use to keep the proportions correct. Let he used x cups of milk.
[tex]\dfrac{1.5}{3}=\dfrac{x}{5}\\\\x=\dfrac{1.5\times 5}{3}\\\\x=2.5[/tex]
Hence, he should use 2.5 cups of milk.

Each triangle weighs 2.5 pounds,each circle weighs 3 pounds, and x represents the weight of each square. Select all equations that represent the hanger.
Step-by-step explanation:
x+x+x+x+2.5(2)+3(2)=x+x+2.5+3(3)
4x+5+6=2x+2.5+9
4x+11=2x+11.5
-11 -11
4x=2x+0.5
-2x -2x
2x=0.5
x=0.25
The equation that can be used to represent the hanger is x + x + x + x + 11 = x + x + 11.5, and 4x + 2.5 + 2.5 + 6 = 2x + 2.5 + 3 + 3 + 3
Given:
Each triangle = 2.5 pounds
Each circle = 3 pounds
Each square = x pounds
The hanger has two sides
Side 1:
squares = 4
Triangle = 2
Circle = 2
Side 2:
Squares = 2
Triangle = 1
Circle = 3
The equation:
side A = side B
4(x) + 2(2.5) + 2(3) = 2(x) + 1(2.5) + 3(3)
4x + 5 + 6 = 2x + 2.5 + 9
4x + 11 = 2x + 11.5
x + x + x + x + 11 = x + x + 11.5
Therefore, equation that can be used to represent the hanger is x + x + x + x + 11 = x + x + 11.5, and 4x + 2.5 + 2.5 + 6 = 2x + 2.5 + 3 + 3 + 3

Answer:

Step-by-step explanation:
The Slope of line (1, 1) and (3, 9) is 4.
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the
change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
The Figure of the graph is attached below.
We have the Coordinates as (1, 1) and (3, 9).
So, the slope of line
= (9- 1)/ (3-1)
= 8/ 2
= 4
Thus, the slope of line is 4.

The equation of the line that contains diagonal HM is y = 2/3 x + 7.
What is the slope of the line that contains diagonal OE?
Answer:
The slope of the line that contains diagonal OE will be = -3/2
Step-by-step explanation:
We know the slope-intercept form of the line equation
y = mx+b
Where m is the slope and b is the y-intercept
Given the equation of the line that contains diagonal HM is y = 2/3 x + 7
y = 2/3 x + 7
comparing the equation with the slope-intercept form of the line equation
y = mx+b
Thus, slope = m = 2/3
We know that the diagonals are perpendicular bisectors of each other.As we have to determine the slope of the line that contains diagonal OE.
As the slope of the line that contains diagonal HM = 2/3
We also know that a line perpendicular to another line contains a slope that is the negative reciprocal of the slope of the other line.
Therefore, the slope of the line that contains diagonal
OE will be = -1/m = -1/(2/3) = -3/2
Hence, the slope of the line that contains diagonal OE will be = -3/2
