Answer: R = 38.7
Explanation:
The diagram of the vectors is shown below
To find the resultant, R, we would apply the pythagorean theorem which states that
hypotenuse^2 = one leg^2 + other leg^2
From the diagram,
hypotenuse = R
One leg = 17.3
other leg = 34.8
Thus,
R^2 = 17.3^2 + 34.8^2 = 299.28 + 1211.04 = 1501.32
R = √1501.32
R = 38.7
To find the direction, we would find θ by applying the tangent trigonometric ratio which is expressed as
tanθ = opposite side/adjacent side
adjacent = 17.3
opposite side = 34.8
tan θ = 34.8/17.3 = 2.01156
Taking the tan inverse of 2.01156,
θ = tan^-1(2.01156)
θ = 63.6
The direction is 63.6 degrees

What are geometric shapes in mathematics?
In Mathematics, Geometric shapes are the figures which demonstrate the shape of the objects we see in our everyday life. In geometry, shapes are the forms of objects which have boundary lines, angles and surfaces. There are different types of 2d shapes and 3d shapes.
Shapes are also classified with respect to their regularity or uniformity. A regular shape is usually symmetrical such as a square, circle, etc. Irregular shapes are asymmetrical. They are also called freeform shapes or organic shapes. For example, the shape of a tree is irregular or organic.
In plane geometry, the two-dimensional shapes are flat shapes and closed figures such as circles, squares, rectangles, rhombus, etc. In solid geometry, the three-dimensional shapes are cube, cuboid, cone, sphere and cylinder. We can observe all these shapes in our daily existence also. For example books (cuboid shape), glasses (cylindrical shape), traffic cones (conical shape) and so on.
Now
As the scale factor for similar shapes V and U is 5:1.
Then their area should also be in same ratio.
Given Area of V=75 square yard
Therefore,
Area of U=75/5
Area of U =15 square yard

((1/3)x^2))-((1/9)x)-(2/9)=0
The solution of the quadratic equation (1/3)x² - (1/9)x - 2/9 = 0 are x = 1, - 2/3.
Any equation that can be written in the standard form where x stands for an unknown and a, b, and c are known quantities, with a 0, is said to be quadratic.
An assignment of values to the unknown variables that establish the equality in the equation is referred to as a solution.
Consider the expression,
(1/3)x² - (1/9)x - 2/9 = 0
Multiplying each side of the quadratic equation by 9,
9 × [ (1/3)x² - (1/9)x - 2/9 = 0 ]
3x² - x - 2 = 0
Using the quadratic formula,
\(x = \frac{-b \pm \sqrt{b^2-4ac} }{2a}\)
\(x = \frac{1 \pm \sqrt{1+24} }{6}\\ x = \frac{1 \pm \sqrt{25} }{6}\)

Of all rectangles with a perimeter of 29, which one has the maximum area? (Give the dimensions.) Let A be the area of the rectangle. What is the objective function in terms of the width of the rectangle, w? Aequals 14.5 w minus w squared (Type an expression.) The interval of interest of the objective function is nothing. (Type your answer in interval notation. Use integers or simplified fractions for any numbers in the expression.) The rectangle that has the maximum area has length nothing and width nothing. (Simplify your answer.)
Answer:
For maximum area: Its a square of dimensions 7.25 * 7.25.
Step-by-step explanation:
We can use calculus to solve this:
Let the length of the rectangle be L and the width be W then we have
2L + 2W = 29
L + W = 14.5
W = 14.5 - L
Area = WL
A = L(14.5 - L)
A = 14.5L - L^2
We need this to be a maximum.
Finding the derivative:
dA/dW = 14.5 - 2L = 0 for a maximum
2L = 14.5
L = 7.25
Also W = 14.5 - L
= 14.5 - 7.25 = 7.25.
So the dimensions for maximum area are 7.25 * 7.25.
The figure is a SQUARE.
The perimeter of a rectangle, is the sum of its side lengths.
The rectangle that has the maximum area when the length is 7.25 and the width is 7.25
The perimeter is given as:
\(\mathbf{P = 29}\)
Let the dimensions be l and w.
So, we have:
\(\mathbf{2( l + w) = 29}\)
Divide both sides by 2
\(\mathbf{l + w = 14.5}\)
Make l the subject
\(\mathbf{l = 14.5 - w}\)
The area of a rectangle is:
\(\mathbf{A = lw}\)
Substitute \(\mathbf{l = 14.5 - w}\)
\(\mathbf{A = (14.5 - w)w}\)
Open brackets
\(\mathbf{A = 14.5w - w^2}\)
Differentiate
\(\mathbf{A' = 14.5 - 2w}\)
Set to 0
\(\mathbf{14.5 - 2w = 0}\)
Collect like terms
\(\mathbf{2w = 14.5}\)
Divide both sides by 2
\(\mathbf{w = 7.25}\)
Recall that: \(\mathbf{l = 14.5 - w}\)
So, we have:
\(\mathbf{l = 14.5 - 7.25 = 7.25}\)
Hence, the rectangle that has the maximum area when the length is 7.25 and the width is 7.25

Step-by-step explanation:
Just finished the homework and got it right
Using exponential functions, it is found that the correct option is given by: [15, ∞)
-------------------------
The exponential function given in this exercise is:
\(M(t) = 25000(\frac{4}{5})^t\)
-------------------------
The domain that contains all the years the car's value is less than $1,000 is composed by the values of t for which:
\(M(t) < 1000\)
Thus, we have to solve the exponential inequality.
\(M(t) < 1000\)
\(25000(\frac{4}{5})^t < 1000\)
\((\frac{4}{5})^t < \frac{1}{25}\)

Solving a system of equations we can see that:
She needs to use 56 oz of the 85% solution.She needs to use 14 oz of the 60% solution.How many ounces of each solution should she use?We can use the variables:
x = mass of the 60% solution.
y = mass of the 85% solution.
We can write a system of equations.
x + y = 70
x*0.6 + y*0.85 = 70*0.8
We can isolate x on the first equation to get:
x = 70 - y
Replace that in the other one:
(70 - y)*0.6 + y*0.85 = 70*0.8
Now we can solve this for y.
y*0.25 = 70*0.8 - 70*0.6
y = 14/0.25 = 56

x = 28.3 degree
We have to given that;
In a triangle,
Two angles are, 61.7 degree and 90 degree
And, One side is, 14.76.
Now, We can formulate;
sin 61.7° = Perpendicular / Hypotenuse
sin 61.7° = z / 14.76
0.88 = z / 14.76
z = 0.88 x 14.76
z = 12.99
And, By Pythagoras theorem we get;
14.76² = z² + y²
14.76² = 12.99² + y²
217.85 = 168.74 + y²
y² = 217.85 - 168.74
y² = 49.1
y = 7.01
And, By sum of all the angles in triangle, we get;
x + 61.7 + 90 = 180

Answer:
Event Probability
Heads \(\dfrac{3}{5}\)
Tails \(\dfrac{2}{5}\)
Step-by-step explanation:
If a coin is tossed 25 times, then from the given table it is clear that
Number of heads = 15
Number of tails = 10
Total number of tosses = 15+10 = 25
We know that,
\(Probability=\dfrac{\text{Favorable outcomes}}{\text{Total number of outcomes}}\)
\(P(H)=\dfrac{\text{Number of heads}}{\text{Total number of tosses}}=\dfrac{15}{25}=\dfrac{3}{5}\)
\(P(T)=\dfrac{\text{Number of tails}}{\text{Total number of tosses}}=\dfrac{10}{25}=\dfrac{2}{5}\)
So, probability distribution table is
Event Probability
Heads \(\dfrac{3}{5}\)
Tails \(\dfrac{2}{5}\)
According to the properties for a probability distribution, the sum of probability of all events is 1.
Since,
\(\dfrac{3}{5}+\dfrac{2}{5}=\dfrac{3+2}{5}=\dfrac{5}{5}=1\)
Hence, the distribution meets the properties for a probability distribution.
carey correctly graphs a liner function. the slope of the function is -1. the y-intercept is 3. which is careys graph
Carey's graph will be a straight line with a slope of -1 and a y-intercept of 3.
Carey correctly graphs a linear function with a slope of -1 and a y-intercept of 3. A linear function is represented by the equation y = mx + b, where m is the slope and b is the y-intercept.
In this case, the slope is -1, which means that for every unit increase in the x-coordinate, the y-coordinate decreases by 1 unit. The y-intercept is 3, indicating that the graph intersects the y-axis at the point (0, 3).
To plot the graph, Carey starts by marking the point (0, 3) on the graph. Then, for every unit increase in the x-coordinate, Carey moves one unit downward. Similarly, for every unit decrease in the x-coordinate, Carey moves one unit upward. These steps ensure the correct slope of -1.
After connecting the points, Carey will obtain a line that starts at the y-intercept (0, 3) and slants downward, with a slope of -1. The resulting graph will be a straight line extending to both sides of the coordinate plane.
In conclusion, it is represented by the equation y = -x + 3.

Conniving these points and connecting them, we get a V- shaped graph that's reflected vertically and shifted 4 units to the left wing.
To graph the function g( x) = - f( x 4), we need to start with the graph of the function f( x) = | x| and also apply the given metamorphoses. The function f( x) = | x| represents the absolute value function, which is a V- shaped graph symmetric with respect to the y- axis.
First, we shift the graph of f( x) = | x| horizontally by 4 units to the left by replacing x with( x 4). This results in f( x 4). Next, we multiply the entire function by-1, which reflects the graph vertically. This gives us- f( x 4). Combining these metamorphoses, we've the function g( x) = - f( x 4). To graph g( x), we can compass a many points and also draw the graph by connecting them.
Let's start with the original graph of f( x) = | x| and apply the metamorphoses
For f( x) x = -3,-2,-1, 0, 1, 2, 3
f( x) = 3, 2, 1, 0, 1, 2, 3 For
g( x) = - f( x 4) x = -7,-6,-5,-4,-3,-2,-1

Each friend had originally 13 action figures before buying 11 more.
Given that there are 5 friends and each of them has x action figures in his or her collection. When they buy 11 more action figures, the total number of action figures they will have is 120.
a) We need to find an equation that models the problem. Let x be the original number of action figures that each friend had.
Therefore, the total number of action figures that each friend will have after purchasing 11 more is x + 11.
The total number of action figures will be 5(x + 11) = 5x + 55.
Now, according to the problem,5x + 55 = 120
This is our equation that models the problem.
b) We have to solve the equation 5x + 55 = 120 to find the original number of action figures, x, that each friend had before buying 11 more action figures.
5x + 55 = 120
5x = 120 - 55 (subtract 55 from both sides)
5x = 65x = 13
Therefore, each friend had originally 13 action figures before buying 11 more.
