Two 10 pound forces act on the same object at the same time. Find the
magnitude of their resultant if 135° is between the two forces.
Final Answer:
The magnitude of the resultant force when two 10 pound forces act on the same object 135° apart is approximately 18.47 pounds.
Explanation:
To find the magnitude of the resultant force when two forces are acting at an angle to each other, we can use the law of cosines. In this scenario, we have two forces each of 10 pounds acting on an object with an angle of 135° between them. Let's denote the forces as F1 and F2, both of which have magnitudes of 10 pounds. The angle between them is θ = 135°.
The formula for the resultant force R when two forces act at an angle θ is:
[tex]\[ R = \sqrt{F1^2 + F2^2 + 2 \cdot F1 \cdot F2 \cdot \cos(θ)} \][/tex]
In our case:
[tex]\[ F1 = F2 = 10 \, \text{pounds} \][/tex]
[tex]\[ θ = 135° \][/tex]
Plugging these values into the formula, we get:
[tex]\[ R = \sqrt{10^2 + 10^2 + 2 \cdot 10 \cdot 10 \cdot \cos(135°)} \][/tex]
[tex]\[ R = \sqrt{100 + 100 + 200 \cdot \cos(135°)} \][/tex]
The cosine of 135° is -√2/2 (since 135° is in the second quadrant where the cosine is negative):
[tex]\[ R = \sqrt{200 - 200 \cdot \frac{-\sqrt{2}}{2}} \][/tex]
[tex]\[ R = \sqrt{200 + 100\sqrt{2}} \][/tex]
[tex]\[ R = \sqrt{200 + 100 \cdot 1.414} \] (Since √2 is approximately 1.414)[/tex]
[tex]\[ R = \sqrt{200 + 141.4} \][/tex]
[tex]\[ R = \sqrt{341.4} \][/tex]
[tex]\[ R \approx 18.47 \text{ pounds} \][/tex]
Therefore, the magnitude of the resultant force when two 10 pound forces act on the same object 135° apart is approximately 18.47 pounds.

Tickets numbered 1 to 20 are placed in a hat. Two tickets are drawn out at random, without
replacement. Find the probability that:
a: the first number drawn is even and the second number is odd
b: both of the numbers are prime.
-please help include explanation too, it would be really helpful if u can!-
Answer: 5/19
Step-by-step explanation:
There is a total of 20 tickets numbered from 1 to 20.
10 of the tickets has even number and 10 of the tickets have odd numbers.
probability of drawing a ticket that has even number =10/20 which is equal to 1/2
there are total 19 tickets and 10 odd tickets are available.
Probability of drawing a ticket that has odd number =1019
probability =1/2∗10/19=5/19
Answer:
a. 5/19, b. 14/95
Step-by-step explanation:
a. since the first number drawn has 10/20 chance of being even and it's not put back (you assume that you pull an even #), so the second number pulled has a 10/19 chance of being odd.
10/20*10/19 = 5/19
b. 2, 3, 5, 7, 11, 13, 17, 19 are the prime numbers, so 8/20 for the first pull and then 7/19 for the second pull
8/20*7/19 = 14/95
A house was bought for £100,000
Its value appreciates by 7.5% each year for the Nirst three years. What was its value at the end of the three years?
Answer:
122500
Step-by-step explanation:
The formula
A=p(1+rt)
A ?
P 100000
R 0.075
T 3 years
A=100,000×(1+0.075×3)
A=122500
Final answer:
The value of the house at the end of three years would be approximately £123,696.47.
Explanation:
To find the value of the house at the end of three years, we need to calculate the appreciation for each year and add it to the original value. Since the value of the house appreciates by 7.5% each year, we can calculate the value after three years using the formula:
New Value = (1 + Rate of Appreciation) * Original Value
Let's calculate:
New Value after first year = (1 + 0.075) * £100,000 = £107,500New Value after second year = (1 + 0.075) * £107,500 = £115,062.50New Value after third year = (1 + 0.075) * £115,062.50 = £123,696.47The value of the house at the end of the three years would be approximately £123,696.47.

For his craft project, James bought 1010 10 10 pieces of ribbon that were each 2.1 feet2.1\text{ feet} 2.1 feet 2, point, 1, start text, space, f, e, e, t, end text long. How many total yards of ribbon did James buy?
To find the total yards of ribbon, convert the length of each piece of ribbon from feet to yards and multiply it by the total number of pieces. James bought 707 yards of ribbon.
Explanation:To find the total yards of ribbon, we need to convert the length of each piece of ribbon from feet to yards and then multiply it by the total number of pieces.
Since 1 yard is equal to 3 feet, we can use the conversion factor of 1 yard/3 feet to convert each piece of ribbon from feet to yards.
2.1 feet x (1 yard/3 feet) = 0.7 yards
Now, we can multiply the converted length of each piece of ribbon (0.7 yards) by the total number of pieces (1010) to find the total yards of ribbon:
0.7 yards x 1010 = 707 yards
Therefore, James bought a total of 707 yards of ribbon.

In a game, four cards are labeled N, S, E, and W. Two tiles are numbered 1 and 2. Two discs are red and blue. A player randomly selects one card, one tile, and one disc.
Find the probability the player selects a card with S or E, a tile with 2, and a red disc.
Answer:
The probability is 1/8.Step-by-step explanation:
Two find the final probability asked, first we need to find each probability.
Probability of a card with S or E.This probability is defined by the sum of the probability of getting a card with S, and a probability of getting a card with E. Remeber, when the probability involves "or", that means sum.
[tex]P_{S \ or \ E} =\frac{1+1}{4}=\frac{2}{4} =\frac{1}{2}[/tex]
Probability of a tile with 2.There are two tiles only, and one of them is numbered 2. So, its probability is
[tex]P_{2}=\frac{1}{2}[/tex]
Probability of a red disc.There are two discs only. So, the probability of getting a red disc is
[tex]P_{red}=\frac{1}{2}[/tex]
Now, the combined probabilty of all these events can be found by multiplying, because we want to now the chances of getting all these results which are independent.
[tex]P_{total}=\frac{1}{2} \times \frac{1}{2} \times \frac{1}{2} =\frac{1}{8}[/tex]
Therefore, the probability is 1/8.
1. A baseball player hits a baseball into the air with an initial vertical velocity of 72 feet per second from a height of 3 feet. ( h = -16t2 +72t +s )
Answer:
You actually do not ask anything here, so i will find the equation for the height and i will use it to find something useful, like the maximum height of the baseball.
For any object in a vertical motion, the only force acting on it is the gravitational force, so the acceleration of the object will be equal to g.
a(t) = -g
where the minus sign is because the gravitational acceleration pulls down.
For the velocity we can integrate over time, and get:
v(t) = -g*t + v0
Where v0 is the initial velocity, in this case v0 = 72 ft/s
v(t) = -g*t + 72ft/s
with this equation we can find the time in wich the height is maximum, we need to find the time where the velocity is 0.
-g*t + 72 = 0
t = 72/g
for the height we can integrate over time again:
h(t) = (-g/2)*t^2 + 72ft/s*t + h0
where h0 is the initial height, in this case h0 = 3ft
here we can also replace the value of g = 32ft/s^2
h(t) = (-16ft/s^2)*t^2 + 72ft/s*t + 3ft
Now we can evaluate this in the time that we previously find, t = 72/g = 72/32 = 2.25s
h(2.25s) = -16*2.25^2 + 72*2.25 + 3 = 85.08 feet

The paper cup is 9 cm tall and the circular opening has a radius of 2.5 cm.
What is the minimum amount of paper needed to make the paper cup to the nearest whole cm² assuming no overlap in the paper?
Final answer:
The minimum amount of paper needed to make the paper cup to the nearest whole cm² is approximately 283 cm².
Explanation:
To find the minimum amount of paper needed to make the paper cup, we need to calculate the surface area of the cup. The formula for the surface area of a cylinder is:
A = 2πrh + π[tex]r^2[/tex]
Given that the height (h) of the cup is 9 cm and the radius (r) of the circular opening is 2.5 cm, we can plug in the values to calculate the surface area:
A = 2 × 3.14159 × 2.5 × 9 + 3.14159 × [tex]2.5^2[/tex]
Simplifying the equation, we get:
A ≈ 282.74 [tex]cm^2[/tex]
Rounding to the nearest whole , the minimum amount of paper needed is approximately 283 [tex]cm^2.[/tex]

1) If a die is rolled once, determine the probability of rolling a 4: Rolling a 4 is an event with 1 favorable outcome (a roll of 4) and the total number of possible outcomes is 6 (a roll of 1, 2, 3, 4, 5, or 6). Thus, the probability of rolling a 4 is [tex]\frac{1}{6}[/tex].
If a die is rolled once, determine the probability of rolling at least a 4: Rolling at least 4 is an event with 3 favorable outcomes (a roll of 4, 5, or 6) and the total number of possible outcomes is again 6.

If a correlation coefficient of -0.898 is given for comparing two things, what does this number tell you about the correlation of the two things?
strong positive
strong negative
weak negative
no correlation
Answer: Strong negative
Step-by-step explanation:
Correlation coefficient tells about the strength ( Strong , moderate or weak ) and direction ( positive or negative) of the relationship between two quantities.
Strong correlation: The value of correlation coefficient lies between -1 to -0.5 or 0.5 to 1.Moderate correlation : The value of correlation coefficient lies between -0.5 to -0.3 or 0.3 to 0.5.Weak correlation : The value of correlation coefficient lies between -0.3 to -0.1 or 0.1 to 3.The given correlation coefficient :-0.898
Since, it lies between -1 and -0.5 and has negative sign, it means it indicates a strong negative between the two things.
Hence, the correct answer is "strong negative ".

The graph shows the function g(x) for a restricted domain.
On a coordinate plane, a function starts at (negative 4, 0) and then curves through the y-axis at (0, 1.5) and then goes through point (4, 2).
Which is the function g(x) for a restricted domain?
g(x) = Negative RootIndex 3 StartRoot x minus 4 EndRoot; x greater-than-or-equal-to –4
g(x) = Negative RootIndex 3 StartRoot x 4 EndRoot + 4; x greater-than-or-equal-to 0
g(x) = Negative RootIndex 3 StartRoot x + 4 EndRoot; x greater-than-or-equal-to –4
g(x) = Negative RootIndex 3 StartRoot x EndRoot minus 4; x greater-than-or-equal-to 0
Answer:
Option 3
g(x) = Negative RootIndex 3 StartRoot x + 4 EndRoot; x greater-than-or-equal-to –4
Step-by-step explanation:
Since the graph starts at x = -4 and towards the right, domain is x 》-4
g(x) = -(x + 4)^⅓
Because,
0 = -(-4 + 4)^⅓
0 = 0
The function g(x) for the restricted domain is g(x) = -∛(x-4); x ≥ -4.
Explanation:The function g(x) for the restricted domain can be determined by analyzing the given information. The function starts at (-4, 0) and curves through the y-axis at (0, 1.5) before passing through point (4, 2). Based on this, the correct function is g(x) = -∛(x-4); x ≥ -4.
