How many x-intercepts does the graph of the function y= 3x^2 - 6x + 5 have?

For 10.75 years I'll receive an amount of $1,193 for an annuity of $12,083.

Simple interest is often a predetermined percentage of the principle amount borrowed or lent paid or received over a specific time period.

We know simple interest (SI) is given by SI = (p×r×t)/100, where

p = principle, r = rate in percentage, and t = time in years.

A principle of $12,083 with 6.1% interest rate becomes $(12,083×1.061)

= $12,820.063.

∴ The no. of years the annuity provides you with payments of $1,193 is

= (12,820.063/1193).

= 10.75 years Or 10 years 9 months.

The option 1 "Similar due to SSS and a scale factor of 3.5. Triangle QRS is similar to triangle VUT." is correct.

In the given question, the triangles below are similar.

So, we have to state the reason and write the similarity statement.

ΔQRS≈

(a) Similar due to SSS and a scale factor of 3.5. Triangle QRS is similar to triangle VUT.

(b) Similar to due SAS and a scale factor of 0.29. Triangle QRS is similar to triangle TUV.

(c) Similar due to AA. Triangle QRS is similar to triangle VUT.

(d) Similar due to SSS and a scale factor of $0.29$. Triangle QRS is similar to triangle VUT.

As we know that, the ratio of the scale of an original thing to a new object that is a representation of it but of a different size is known as a scale factor.

Since the both triangle area similar so using the SSS theorem;

Triangle QRS congruence to triangle VUT.

QR/VU = RS/UT = SQ/TV

So QR/VU = 56/16; RS/UT = 70/20; SQ/TV = 98/28

QR/VU = RS/UT = SQ/TV = 3.5

Hence, ΔQRS≈ΔVUT using the SSS theorem with the scale factor of 3.5. So the option 1 "Similar due to SSS and a scale factor of 3.5. Triangle QRS is similar to triangle VUT." is correct.

Answer:

Step-by-step explanation:

180 = x + 50 +50

180 = x + 100

x + 100 = 180

x = 80

80 is the value of x.

Inequality:

y > 1/3x - 3

We can say that the view in which one or more faces of the object are not perpendicular to the rest of the faces, but are inclined projections, are the auxiliary views.

Initially, we must know that the views of an object or body are orthogonal projections associated with it.

In this sense, auxiliary views are a type of view that are characterized by arising from a change in projection plane, they are usually used when highly complex parts or objects must be represented.

If the two lines have same y-intercept then this is the point of intersection of the two lines.

Since the slopes are different, the y-intercept is the only point of intersection. So there is one solution.

Correct choice is D.

Equation of the line passes through (10,2) and is perpendicular to the line y = 2x is given by  y = -x / 2 + 7.

As given in the question,

Given equation of the line :

y = 2x

Line passes through the point (x₁ , y₁ ) = (10, 2)

Standard form of slope intercept form

y = mx + c

'm' is the slope

slope of the given line 'm₁' = 2

let 'm₂' be the slope of the required line

Multiplication of the Slope of two perpendicular lines is given by :

m₁ × m₂ = -1

⇒2 × m₂ = -1

⇒m₂ = -1/2

Equation of the line perpendicular to the given line and passes through

What is circle?

A circle is a two-dimensional geometric shape defined by a set of points equidistant from its center. It is the set of all points in a plane that are the same distance from a given point, called the center. A circle is a special type of ellipse, and all circles are similar. It is one of the most fundamental shapes in geometry, and is used in art, architecture, engineering, and many other disciplines. The circumference of a circle is the length of its perimeter, which is determined by its radius. A circle's area is the space enclosed by its circumference, and is equal to the value of pi multiplied by the square of the radius.

The equation of the conic represents a circle with an area of 36π square units.

In this problem we find the equation of the conic in general form, on which we need to determine what kind of conic it represents. This can be done by finding the standard form of the equation by means of algebra properties, using a strategy known as completing the square. The quadratic equation in general form is described by the quadratic equations of the form:

A · x² + B · y² + C · x + D · y + E · x · y + F = 0

Now we proceed to find the standard form of the equation. First, write the equation in standard form:

x² + y² - 3 · x + 6 · y = 7 · x + 2

x² + y² - 10 · x + 6 · y - 2 = 0

Second, complete the square:

(x² - 10 · x + 25) + (y² + 6 · y + 9) = 2 + 25 + 9

(x - 5)² + (y + 3)² = 36

The standard form of the quadratic equation indicates the equation of a circle with a diameter of 12 units and a center at (h, k) = (5, - 3). The area of the circle is calculated below:

A = 0.25π · D²

Where D is the diameter of the circle, in units.

Answer:

Step-by-step explanation:

The sum of exterior angles in a quadrilateral is always 360 degrees.

So, 2x+x+4x+3x=10x=360

Soling for x, we get x=36 degrees.

The number that must be added to complete the square in the expression is 0.9².

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

x² + 1.8x

The complete square is given as,

(a + b)² = a² + 2ab + b²

Now,

x² + 2 x 0.9(x) + 0.9²

(x + 0.9)²

The equation of the line in slope-intercept form is y = 3x - 11.

We know lines have various types of equations, the general type is

Ax + By + c = 0, and the equation of a line in slope-intercept form is

y = mx + b.

Where slope = m and b = y-intercept.

the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.

We know slope(m) = (y₂ - y₁)/(x₂ - x₁).

∴ Slope(m) = (- 5 + 8)/(1 - 0) = 3.

So, y = mx + b can be written as - 5 = 3(2) + b ⇒ b = - 11.

So, The required line is y = 3x - 11.

If y varies directly as x and z, and y=4 when x=6 and z=1, then value of y will be 56/3 when x=7 and z=4.

One kind of proportionality relationship is the direct proportion. When two values are in direct proportion, one value rises when the other rises and vice versa when one value falls. A proportionate relationship is represented by the symbol. When one of the variables is a multiple of the other, there is a direct proportion between the two. For instance, 1 cm equals 10 mm. The multiplier for converting cm to mm is always 10. Petrol prices and foreign exchange rates are determined using a direct proportion.

Given,

We know that y fluctuates in direct proportion to x and z.

We are aware that the form of the equation y = kx for two quantities that are directly proportional is, where k is the proportionality constant.

Because y directly varies as x and z, our equation would be y = kxz

Additionally, it is stated that and y = 4, x = 6 and z = 1. Let's define the proportionality constant as follows:

4 = k × 6 × 1

4 = k ×6

k = 2/3

y = 2/3 × x ×z

Substituting value of x by k = 2/3 , x = 7 and z = 4

y = 2/3 × 7 × 4

y = 56/3

If y varies directly as x and z, and y=4 when x=6 and z=1, then value of y will be 56/3 when x=7 and z=4.

From the question, we have the following parameters that can be used in our computation:

y = -x^2 + 50x - 80

Rewrite this function as

y = -x² + 50x - 80

Differentiate the function

So, we have

y = -2x + 50

Set to 0

-2x + 50 = 0

So, we have

2x = 50

Divide  by 2

x = 25

Recall that

y = -x² + 50x - 80

Also, we have

x = 25

So, we have

y = -(25)² + 50 x 25 - 80

The percentage error when the weight was found to be 62.5 ounces is 3.2%.

A percentage is a value or ratio that may be stated as a fraction of 100. If we need to calculate a percentage of a number, we should divide it's entirety and then multiply it by 100.

The percentage therefore refers to a component per hundred. Per 100 is what the word percent means. It is represented by %.

Since the the weight of the sample as 60.5 ounces and the true weight was found to be 62.5 ounces.

The percentage error will be:

Error / Initial value × 100

= (62.5 - 60.5) / 62.5 × 100

= 2 / 62.5 × 100
