Find the equation of a line that passes through the points (2, 5) and (5, -4)

Answer:

To divide 3 4/7 by 2/5, you will need to convert the mixed number 3 4/7 to an improper fraction. To do this, you will multiply the whole number (3) by the denominator of the fraction (7) and add the numerator (4) to get an improper fraction of 25/7.

Next, you will divide the numerator of the first fraction (25) by the numerator of the second fraction (2) and divide the denominator of the first fraction (7) by the denominator of the second fraction (5). So the answer is 25/2 divided by 7/5 which is equivalent to 25/2 * 5/7 = 25/14 which can be simplified further to 5/2

On solving the provided question, we can say that volume of cylinder v = 4.13 * 10*10*5 = 2065 cubic units  

One of the most fundamental curved geometric forms is the cylinder, which is often a three-dimensional solid. It is referred to as a prism with a circle as its base in elementary geometry. Several contemporary fields of geometry and topology also define a cylinder as an indefinitely curved surface. A three-dimensional object known as a "cylinder" consists of curving surfaces with circular tops and bottoms. A cylinder is a three-dimensional solid figure that has two bases that are both identical circles joined by a curving surface at the height of the cylinder, which is determined by the distance between the bases from the center. Examples of cylinders are cold beverage cans and toilet paper wicks.

here, we have

r = 10

Lines a and b have the same slope.

What is a slope?

The value of the steepness or the direction of a line in a coordinate plane is referred to as the slope of a line, also known as the gradient. Given the equation of a line or the coordinates of points situated on a straight line, a slope can be determined using a variety of approaches.

Here, we have

Given: Line a passes through the points (-1, 2) and (3, 4).

Line b passes through the points (-5, 0) and (3, 4).

We find the slope of both lines and we get

Line a has points (-1, 2) and (3, 4).

Slope = (y₂ -y₁)/(x₂ -x₁)

m = (4 - 2) / (3+1)

m = 2/4

m = 1/2

Line b has points (-5, 0) and (3, 4).

Slope = (y₂ -y₁)/(x₂ -x₁)

m = (4 -0)/(3+5)

m = 4/8

m = 1/2

The model of the growth of the quantity is A(t) = 350(1.10)^t.  The expression for the size of the quantity after 50 years is A(50) = 350(1.10)⁵⁰.

What is a function?

A function is defined as a relationship between a set of inputs that each have one output. A function is a relationship between inputs in which each input is related to exactly one output.

Given that a quantity starts with a size of 350 and grows by 10% per year.

The growth of the object can be calculated by using the exponential function:

A = P(1+r)^t

A = final amount

P =  initial size

r = rate of increasing

Here P = 350, r = 10% = 0.10

The model becomes:

A(t) = 350(1+0.10)^t

A(t) = 350(1.10)^t

To find the quantity after 50 years, put t = 50 in A(t) = 350(1.10)^t:

You can use the law of sines along with the angle of elevation given to find out the length of the distance of the vertical beam from the lower end of the support beam(horizontally).

The distance between lower end of the support beam from the vertical beam along the horizontal floor is given by

Option A: 3.0 meters

What is law of sines?

For any triangle ABC, with side measures |BC| = a. |AC| = b. |AB| = c,

we have, by law of sines,

[tex]\frac{sinA}{a}= \frac{sinB}{b} = \frac{sinC}{c}[/tex]

Remember that we took

[tex]\frac{sin(angle)}{Length Of The Side Opposite To That Angle}[/tex]

Using the law of sines, as referring in the figure attached below, we get:

[tex]\frac{sinC}{|AB|} = \frac{sinA}{|BC|}[/tex]

Since in a triangle, the sum of its angle is 180 degrees, thus,

∠A + ∠B + ∠C = 180°

∠A = 180°- 28° - 90° = 62°

Using the fact that |AB| = 1.6 meters and that angle C is of 28°, we get

[tex]\frac{sinC}{|AB|} = \frac{sinA}{|BC|}\\\frac{sin28}{1.6} = \frac{sin62}{|BC|}[/tex]

Using the sin calculator

[tex]\frac{0.469}{1.6} = \frac{0.8829}{|BC|}\\ |BC| = \frac{0.0029*1.6}{0.469} = 3.012[/tex]

|BC| ≈ 3 meters

Thus,

As length of BC = |BC| = 3 meters denote the horizontal length from the vertical beam and the lower end of the support beam, thus,

The distance between lower end of the support beam from the vertical beam along the horizontal floor is given by 3 meters.

Using the Pythagoras theorem, the value of line segment RQ denoted as x is option C: 20 units.

In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem. These triangle's three sides are known as the Perpendicular, Base, and Hypotenuse.

According to the diagram given -

ST = 9 units and TQ = 16 units.

Δ SRQ and Δ STR are equal and congruent as RT is perpendicular to hypotenuse SQ.

From similar triangles,

Δ SRQ ⩭ Δ STR ------(1)

{∵ RT 丄 Hypotenuse SQ}

Similarly, Δ SRQ and Δ RTQ are equal and congruent Δ SRQ, Δ STR and Δ RTQ  are similar right-angled triangles.

Δ SRQ ⩭ Δ RTQ ------(2)

{∵ Δ SRQ, Δ STR and Δ RTQ are similar triangles}

So, this gives that the sides -

SR/ST = SQ/SR = RQ/TR

SR/9 = 25/SR = x/TR

SR² = 25 × 9

SR = 5 × 3 = 15

Now, applying the Pythagoras theorem -

SR² + RQ² = SQ²

RQ² = SQ² - SR²

RQ² = 25² - 15²

RQ = √(625 - 225)

x = RQ = √400

RQ = 20 units

Therefore, the value of x is obtained as 20 units.

There are 67 more baseballs than basketballs.

An equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Given that, a coach buys 125 more soccer balls than basketballs He buys 58 fewer baseballs than soccer balls.

Let the number of soccer balls be x, and that of basketballs and baseballs be y and z respectively.

Therefore, according questions,

x-y = 125

x = 125 + y...(i)

x-z = 58

x = 58 + z...(ii)

Now, since, LHS of both equations are equal,

125 + y = 58 + z

z - y = 67

Since, y is being subtracted by z and result is positive, therefore, number of baseball is greater than number of basket balls,

Hence, there are 67 more baseballs than basketballs.
