Solve the following math problem I. Picture pls

Using the digits 1 to 9 at most one time each to make the largest quotient is 98 ÷ 12 .

According to the question we have to use digits 1 to 9 at most one time each to make the largest quotient.

Now we know that the number that is being divided is known as the dividend and the number by which we divide is known as the divisor.

Now dividend should be greater than the divisor.

So tot make the largest quotient the dividend and the divisor will be

98 and 12 respectively.

That is,     98 ÷ 12 = 8.2 which is the largest quotient.

Answer:

213.7°

Step-by-step explanation:

The bearing of B from D is angle ADB, which is ∠ADB = arctan(30/45)

≈ 33.7°

The bearing of D from B is that angle plus 180°, so is 180° +33.7° = 213.7°

Answer:

225°

Step-by-step explanation:

In mathematics, a bearing is defined as an angle measured clockwise from north.

See attached graph for a clearer guide to the explanations

Angle ABC is a right isosceles triangle with AB = 25 and AC = 25

m∠BAC =90°

So m∠ABC = m∠ACB = 45°

The angle at BC is 45° from the North (90°-45°)  measured clockwise is 45° so we say the bearing from C to B is 045°  (we use 3 digits for bearing)

The bearing from B to C on the other hand is determined by adding 180° to the bearing in the opposite direction (C to B) so the bearing from C to B is 180° +045° = 225°

(Here I am not sure whether you are supposed to answer the question in mathematical meaning of bearing or just state the direction in which BC lies relative to north. 45° clockwise from the North is in a NE direction so we can say C is NE from B but I am guessing that's not it)

A parabola is an approximately U-shaped, mirror-symmetrical plane curve in mathematics. It corresponds to a variety of seemingly unrelated mathematical descriptions, all of which may be shown to define the same curves.

One definition of a parabola includes a line and some extent  (the focus) (the directrix). The directrix isn't the main focus. The locus of points therein plane that is equally spaced apart from the directrix and the focus is known as the parabola. A right circular conical surface and a plane parallel to a different plane that is tangential to the conical surface intersect to form a parabola, which is additionally known as a conic section.

5 = (1/2)2 + 4 is an equation in intercept form for the line passing through the points (2,5) and (6,7)

A line's steepness and direction are determined by the slope of the line. Without actually using a compass, determining a line's slope in a coordinate plane allows one to anticipate whether a line is parallel, perpendicular, or not.

The change in a line's y coordinate relative to its change in x coordinate is referred to as the line's slope. Δy is the net change in the y coordinate, while Δx is the net change in the x coordinate.  

Therefore,

m =  y₂-y₁/x₂-x₁ (where m denotes the slope) can be used to express how the y coordinate changes in relation to the x coordinate.

Be aware that tan ∅ = y/x

We also refer to this tan as the line's slope.

We have been asked to write an equation in slope-intercept form for the line passing through (2,5) and (6,7)

First we will find the slope(m)

We know that slope = m = [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]

For the pairs of points (2,5) and (6,7)

⇒ m = [tex]\frac{7- 5}{6 - 2}[/tex]

⇒ m = [tex]\frac{2}{4 }[/tex]

⇒ m = 1/2

We know that the equation for slope(m) and y - intercept(b) of a line is given by :

y = mx + b

Here lets take equation 5 = (1/2)2 + b .Here x and y is substituted with the first two points.

⇒  5 = (1/2)2 + b

⇒  5 = 1 + b

⇒  b = 5 - 1

⇒  b = 4

The equation in the slope intercept is as follows:-

5 = (1/2)2 + 4

Where:

Information about the problem:

Calculating the "d" term, we have:

d = aₙ₊₁ - aₙ

The length of AC is √3 units and the length of AB is 2 units by Pythagoras' theorem

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

The right-angled triangle ABC has an angle BAC of 30º.

The length of BC  be one unit

We have to find the length of AC

tan (30)= opposite side/ adjacent side

1/√3 = opposite side/ adjacent side

The adjacent side is √3  which is length of AC

Now let us find the length of AB by using pythagoras theorem

In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides

AB² = AC² + BC²

AB²=√3² + 1²

AB²= 4

AB = 2 units

Hence, the length of AC is √3 units and the length of AB is 2 units by Pythagoras' theorem
