into which quadrant does vector $\vec{a}$ = (ax, ay), with ax = 1.5 cm and ay = –1.0 cm, point?

Answer: 36.87 degrees.

Step-by-step explanation:

In a right-angle triangle, the length of the opposite side of an angle and the length of the hypotenuse can be used to find the value of the angle using the trigonometric ratios.

If we let the angle in question be denoted as "theta" and the length of the opposite side be "opp" and the length of the hypotenuse be "hyp", we can use the trigonometric ratio "sine" to find the value of the angle.

sin(theta) = opp/hyp

We are given that opp = 3 cm and hyp = 5 cm, so we can substitute these values into the equation:

sin(theta) = 3/5

We can now use an inverse trigonometric function, such as arcsin, to find the value of theta:

theta = arcsin(3/5)

The result of this calculation is theta = approximately 36.87 degrees. Therefore, the value of the angle is 36.87 degrees.

Answer:

-3(x+4) = 2x-37

(open bracket)

(-3 × x)+ (-3 × 4) = 2x-37

-3x - 12 = 2x-37

The equivalent expression to the given expression ( 5/2) + 2( 2/5) + 7  is given by 11 ( 9 /10) .

Simplify the expression to get the equivalent expression:

( 5/2) + 2( 2/5) + 7

Convert mixed fraction 2( 2/5) into proper fraction we get:

2 ( 2 / 5 ) = ( 5 × 2 + 2 ) / 5

               = 12 / 5

Now, take the least common multiple of denominator we have:

( 5 / 2 ) + ( 12 / 5) + 7 / 1

Least common multiple of 2, 5, 1 is 10

( 5/ 2 ) × ( 5 / 5 ) + ( 12 / 5 )× ( 2/2) + ( 7 / 1) × ( 10 /10)

=( 25 / 10) + ( 24 /10) + ( 70 /10)

= ( 25 + 24 + 70 ) / 10

= 119 / 10

= 11 ( 9 /10)

Therefore, the equivalent expression is equal to 11 ( 9 /10).

The equivalent of log (6) = 0.778 indicates the logarithmic base 10 of 6 is approximately 0.778.

Logarithms are a mathematical concept that are used to simplify exponential calculations. They are the inverse of exponents and are denoted as log base b (x), where b is the base of the logarithm and x is the number you want to find the logarithm of.

In this case, when your calculator computes log (6) as 0.778, it means that the logarithm base 10 of 6 is approximately 0.778.

Answer:A golden rectangle is a rectangle where the ratio of the longer side (the "length") to the shorter side (the "width") is the golden ratio, approximately 1.618.

Let x be the width of the rectangle.

Since the ratio of the length to the width is the golden ratio, we can write the equation:

(x*1.618) = width + x

Solving for x, we get:

x = 54/(1+1.618) = 54/2.618 = 20.5 inches

So the width of the rectangle is 20.5 inches and the length of the rectangle is x1.618 = 20.51.618 = 33.5 inches.

The vectors v and w must be parallel if the value of an is 3/a2.

The parts of each vector must be proportionate for v to be parallel to w.

v = 3ai + 2j

w = (a^2)i + 6j

Therefore,

3a / a^2 = 2 / 6

3a = (2/6)a^2

a = 3/a^2

The components of each vector must be proportionate in order to make two vectors parallel. In this situation, we wish to make v parallel to w because we have two vectors, v and w. We can use the following equations to express v and w:

v = 3ai + 2j

w = (a^2)i + 6j

We need to determine the ratio between the x-components (3a and (a2)) and the y-components (2 and 6), as we can see that they are not currently proportionate. To do this, we can construct a proportional equation where the ratio is 3a / a2 on one side and 2/6 on the other. This problem can be solved for a by simplifying the equation to 3a = (2/6)a2. This yields a value of 3 / a2, indicating that the value of a must be 3 / a2 for v and w to be parallel.

The equation be |2x-3| = 7 then the set of values is the solution set be (2, -5).

An equation is a mathematical statement that proves two mathematical expressions are equal in algebra, and this is how it is most commonly used. When two expressions are joined by an equal sign, a mathematical statement is called an equation.

In mathematics, to solve an equation is to identify its solutions, which are the values (numbers, functions, sets, etc.) that satisfy the requirement expressed by the equation. An equation typically consists of two expressions connected by an equals sign. A variable or variables are labeled as unknowns when looking for a solution.

Any combination of a number, a variable, and operation symbols is considered an expression. Two expressions are combined to form an equation, which is joined by the equal sign.

Let the equation be |2x-3| = 7

We know that if [tex]$|a|=b, a=\pm b$[/tex].

Since we do not know if 2x - 3 exists positive or negative, we will need a [tex]$\pm$[/tex] on the 7 :

[tex]$|2 x-3|=7 \Rightarrow 2 x-3=\pm 7$$[/tex]

Add 3 to both sides, and finally divide by 2, we get

[tex]$$\begin{aligned}& 2 x=3 \pm 7 \\& x=\frac{3}{2} \pm \frac{7}{2}\end{aligned}$$[/tex]

So x exists equal to either 10/2 = 5 or -4/2 = -2.

The result of the normal probability distribution being bell-shaped is that the mean, median, and mode are at the center.

This means that the center of the bell-shaped curve represents the most likely occurrence of the data and that the values are symmetrically distributed around the mean.

The mean, median, and mode of a normal distribution are equal, which means that they are all located at the center of the bell-shaped curve. This is an important characteristic of the normal distribution and sets it apart from other distributions where the mean, median, and mode may not be equal.

In a normal distribution, the area on each side of the mean does not equal 1.00, but rather approaches 1.00 as the curve becomes more symmetrical. The height of the curve at the mean represents the highest probability of occurrence, and the probabilities decrease as the values deviate from the mean.
