Step-by-step explanation:
A pair of tow trucks are pulling on a trailer that is stuck
in mud. The first truck pulls a a pair of tow trucks are pulling on a trailer that is stuck in mud. the first truck pulls with a force of 10,000
pounds at a 110° angle from the second truck, which is
pulling with a force of 7,500 pounds. What is the
magnitude of the resultant force?
9.821 pounds
10,244 pounds
14,405 pounds
24 226 pounds
Answer:
R=10,244 Lb
Step-by-step explanation:
In order to solve this problem, we can start by drawing the situation. (See attached picture).
We can look at the forces applied by the trucks as vectors, so in this case, in order to find the resultant force, we can add the two vectors. You can do so by drawing one force after the other and join the start of the first force with the end of the second force to form a triangle. The missing side will be the resultant force. In that triangle I drew there, the inner angle will be found by subtracting 180°-110°=70°
In this case we can find the resultant force by using the law of cosines:
[tex]A^{2}=B^{2}+C^{2}-2AB cos \alpha[/tex]
so we can use the data given by the problem:
[tex]R^{2}=T_{1}^{2}+T_{2}^{2}-2T_{1}T_{2} cos \alpha[/tex]
so we can solve this for R, so we get:
[tex]R=\sqrt{T_{1}^{2}+T_{2}^{2}-2T_{1}T_{2} cos \alpha}[/tex]
now we can substitute:
[tex]R=\sqrt{(10,000Lb)^{2}+(7,500Lb)^{2}-2(10,000Lb)(7,500Lb) cos (70^{0})}[/tex]
which yields:
R=10,244Lb

Is there a proportional relationship between number of sandwiches and the cost of the order? Explain how you know.
(The picture shows what the relationship is now all I need to find is if it’s proportional or not, and why. Can you help me please? It’s homework, and it’s due in 5 minutes.)
Answer:
No, there is no proportional relationshipStep-by-step explanation:
The proportional relationship is:
y = kx, which is a special form of linear equation, with zero y-interceptIn the given case we have:
y = 4.5x + 10This is a linear function but not proportional relationship because it has y-intercept, different than zero
If f(x) = 2x2 + 7, find f(-3) =
What’s the f(-3)
Answer:
replace the x with -3
Step-by-step explanation:
if you ever have f(x) = 'insert equation' and then it says find f('insert number'), you replace what ever variable is after the first 'f' with the number after the second 'f'. hope this helped!

heather spend 2/7 of her money buying presents. she then had €48.65 left how much had she at first?
Given :
Heather spend 2/7 of her money buying presents.
She then had €48.65 left.
To Find :
The initial amount of money she had.
Solution :
Let, initial amount she had is €x.
So,
[tex]x - \dfrac{2x}{7} = 48.65\\\\\dfrac{5x}{7} = 48.65 \\\\x = \dfrac{48.65\times 7}{5}[/tex]
x = €68.11
Therefore, initially he had €68.11 .

Step-by-step explanation:
The lines represent the lines of symmetry where the image can be reflected upon. Hence it is reflectional.
The dot in the middle of the image tells us that the image can be rotated about the dot to produce the exact same image. Hence it is rotational.
The answer is both rotational and reflectional.
Answer:
I broke it to phrases. Make sure to read both.
It is rotational symmetry. This is because rotational symmetry means it is able to be rotated, and looks the same. This is true with this figure. The lines demonstrate that it is an equal dimensioned 2D shape.
It is ALSO reflection symmetry because this means it can be split through the center and looks exactly the same, as if it was a reflection. This is true here too because it has the same amount of lines split through the same angle on each side making it equal. You can also see a line already going through the shape, and as you can see if you look at see side it looks equal, like a reflection.

Nancy has 7 boxes of tomatoes. Each day, she picks another
2
box. How many boxes of
tomatoes will Nancy have in 6 days? Write an equation, complete the table, and then graph to
solve the problem.
Answer:
19 boxes of tomatoes
Step-by-step explanation:
If she starts with 7 boxes of tomatoes and she picks 2 more each day for 6 days then you can multiply 2 by 6 and get 12 tomatoes then you add the 7 boxes she originally started with and you get 19 boxes of tomatoes.
The number of boxes Nancy had after 6 days is 19, the equation representing the given phrase is y = 2x + 7, and the graph is attached below.
What is graph?A collection of objects is arranged in a graph, where some object pairings are conceptually "linked." Each pair of connected vertices is referred to as an edge, and the objects are represented by mathematical abstractions known as vertices.
Given:
Nancy has 7 boxes of tomatoes,
Each day, she picks another 2 boxes,
The equation which will represent the above phrase is shown below,
Total number of tomatoes = The number of tomatoes she already had + number of days × each day's tomatoes picked by Nancy,
Assume the total number is y and the number of days is x then,
y = 7 + 2 × x
y = 2x + 7
Put the value of x = 6,
y = 2 × 6 + 7
y = 12 + 7
y = 19
Thus, she has a total of 19 boxes of tomatoes after 6 days.

What is the inverse of the function f(x) = 4x + 8?
Answer:
h(x) = (1/4)x - 2 which is choice A
Step-by-step explanation:
Replace f(x) with y. Then swap x and y. Lastly, solve for y to get the inverse.
f(x) = 4x+8
y = 4x+8
x = 4y+8
x-8 = 4y
4y = x-8
y = (x-8)/4
y = x/4 - 8/4
y = (1/4)x - 2
h(x) = (1/4)x - 2
Amy has 20 necklaces in a jewelry box. The probability of reaching into the jewelry box and pulling out a silver necklace is 0.85. What is the probability that Amy will reach in the jewelry box and pull out a necklace that is not silver?
Answer:
0.15
Step-by-step explanation:
Given
[tex]Necklaces = 20[/tex]
Represent the probability of pulling out silver with p; So:
[tex]p = 0.85[/tex]
Required
Determine the probability of not pulling silver
This question is to test probability complements
And the complement rule of probability states that:
[tex]p + q = 1[/tex]
Where q and p are opposites. In other words:
q = probability of not pulling out silver
Substitute 0.85 for p in [tex]p + q = 1[/tex]
[tex]0.85 + q = 1[/tex]
Make q the subject
[tex]q = 1 - 0.85[/tex]
[tex]q = 0.15[/tex]
Hence, the required probability is 0.15
