Resolving F2 into components along the u and v axes, the magnitudes of the components are determined as 150 N and 77.6 N.

According to the sine law, the side length of a triangle should be divided by the sine of the opposite angle. That is, when we divide side a by the sine of angle A, we get the same result as side b divided by angle B and side c divided by angle C.

For the given diagram, first, draw the vector components. Then, by sine law, we get,

[tex]\begin{aligned}\frac{F_u}{\sin 75^{\circ}}=\frac{F_2}{\sin 75^{\circ}}=\frac{F_v}{\sin 30^{\circ}}\end{aligned}[/tex]

Now, substitute the value of F₂, and we get,

[tex]F_u=F_2=\mathrm{150\;N}[/tex]

Now, solve for [tex]F_v[/tex], we get,

[tex]\begin{aligned}F_v&=\frac{F_2\sin 30^{\circ}}{\sin75^{\circ}}\\&=\mathrm{\frac{150\;N\times 0.5}{0.966}}\\&=\mathrm{77.64\;N}\end{aligned}[/tex]

The required answers are 150 N and 77.64 N.

2 is a common sample in the 2 events, therefore they are not mutually exclusive.

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics. The range of the value is 0 to 1. Mathematics has included probability to forecast the likelihood of certain events. The degree to which something is likely to happen is basically what probability means. You will discover the likelihood of outcomes for a random experiment using this fundamental probability theory, which is also applied to the probability distribution.

Two occurrences are mutually exclusive or disjoint in logic and probability theory if they cannot both occur at the same time. The results of a single coin toss, which can result in either heads or tails but not both, provide a clear illustration.

The slope of the line that passes through the points (2, -8) and the origin is calculated using the formula m = rise/run, which gives -4.

In this Mathematics problem, we are asked to find the slope of the line that passes through two points using the formula m = rise/run, where 'm' is the slope. The points provided are (2, -8) and the origin, which is (0, 0).

To find the slope (rise/run), we can subtract the y-values (rise) and the x-values (run) of the two points, respectively. So, the formula becomes: m = (-8 - 0) / (2 - 0) => m = -8/2 = -4.

A. The interest Bianca earned for a period of 3 years is $382.50. The correct option is B. $382.50

B. The number of years Bianca kept the account open is 11 years

From the question, we are to calculate how much interest Bianca will earn for a period of 3 years

From the simple interest formula, we have that

S.I = PRT

Where S.I is the simple interest

P is the principal

R is the rate

and T is the time

From the given information

P = $3,000

R = 4.25% = 0.0425

T = 3

Therefore,

S.I = $3,000 × 0.0425 × 3

S.I = $382.50

B.

From the given information, Bianca receives $4,402.50 when she closes the account

Thus,

The simple interest = $4,402.50 - $3,000

Simple interest = $1402.5

We are to calculate how many years Bianca kept the account open. That is, T

Using the formula,

S.I = PRT

$1402.5 = $3000 × 0.0425 × T

$1402.5 = $127.5 × T

T = $1402.5/$127.5

Solving the example, hope it will help you with better understanding.

Given system:

We need to eliminate one of the variables c or d. Let us eliminate d.

We see the first equation has 3d and the second equation has - d. The coefficients of d are 3 and - 1. If we multiply the second one by 3 it will become - 3, then if we add them up they will cancel, 3d - 3d = 0. By doing this we'll eliminate the variable d and left with variable c in the resulting equation.

Demonstrating how it works:

2c + 3d = 12, we leave it as is

x = 5/19

Step-by-step explanation:

For left side, apply logarithm division property:

[tex] \displaystyle{ \ln a - \ln b= \ln \left( \dfrac{a}{b} \right)}[/tex]

Hence:

[tex] \displaystyle{ \ln \left( \dfrac{x}{4x - 1} \right) = \ln 5}[/tex]

Since both sides have same ln, we can cancel ln both sides:

[tex] \displaystyle{ \dfrac{x}{4x - 1} = 5}[/tex]

Solve the equation for x:

[tex] \displaystyle{x = 5(4x - 1)} \\ \\ \displaystyle{x = 20x - 5} \\ \\ \displaystyle{5 = 20x - x} \\ \\ \displaystyle{5 = 19x} \\ \\ \displaystyle{x = \dfrac{5}{19}}[/tex]

The tangent ratio of F by using the rule from trigonometry is 4/3

Trigonometric ratios are ratios that represent the length of a triangle's sides. In trigonometry, these ratios show how the ratio of a right triangle's sides to each angle. Sine, cosine, and tangent ratios are the fundamental trigonometric ratios.

The sine of the trigonometry ratio is sin θ = opposite/hypotenuse. The cosine of the trigonometry ratio is cos θ = adjacent/hypotenuse. The tangent of the trigonometry ratio is tan θ = opposite/adjacent. From the image given. The opposite side is the line facing the angle F;

Thus, the opposite side = 8, and the adjacent is the smallest side, which is 6.

Therefore, the tangent ratio for F is:

tan θ = 8/6

This can be reduced to 4/3

Therefore, we can conclude that the tangent ratio of F is 4/3.

The angles are said to be in supplementary if and only if the sum of two angles is 180 degrees .

Angles 3 and 4 are supplementary.

The measure of angle 3 is

thirty-five more than one-fourth the measure of angle 4.

So,

∠3 + ∠4 = 180 degrees.

∠3 = 180-∠4 - equation 1

∠3 = 35 + (1/4 ) ∠4 - equation2

As equation 1 and 2 are equal

hence,

180-∠4 = 35 + (1/4) ∠4

180-35 = ∠4 +  (1/4) ∠4

145 =  ((1/4)+1) ∠4

145 = (5/4) ∠4

∠4 = 145 * 4 / 5
