Answer:

Step-by-step explanation:

12x^2+17x = 5

12x^2+17x-5 = 0

(4x - 1)(3x+5) = 0

Solve (4x-1) and (3x +5)

4x - 1 = 0

4x = 1

x = 1/4

3x + 5 = 0

3x = -5

x = -5/3

x = { 1/4, -5/3 }

Graph with their Turning Point is shown with different degree of different degree Equation

Where a graph changes, either from increasing to decreasing, or from decreasing to increasing, is called a turning point.

Factorization Technique

The turning point of the parabola lies exactly at the midway between the (two) x-intercepts of a quadratic function, as shown by the fact that a vertical line of symmetry divides the parabola into two equal half and crosses it. In light of this, we can use a factorisation-based method to locate the solution of a quadratic equation. The process involves five steps.

Step 1: By looking at the coefficient of x2, determine if the graph is a minimum or maximum;

Factorize the supplied quadratic function in Step 2 and set it to Zero;

Step 3: Define the function's antecedents;

Take the midpoint of the pair of roots to find the x-coordinate of the turning point in step 4;

2 turning points

Let f(x)=x³+ax²+bx+c, where the coefficients a, b and c are real numbers. The figure below shows a section of the graph of y=f(x). The curve has two distinct turning points; these are located at A and B, as shown.

But there is come limitations in this case too, a function has to follow certain conditions to have two turning points.

3 turning points

If we get 4 roots of any equation it may be containing 3 turning Points.

With some limitations in this as well.

4 turning points

If we get 5 roots of any quadratic equation it may be containing 4 turning points with some limitations in this as well.

Mr. Henderson paid a total of $98.40 for phone service and $79.20 for garbage pickup last year. To find his average cost per month for these two services, we need to divide the total amount he paid by the number of months in a year.

Since there are 12 months in a year, we can divide the total amount Mr. Henderson paid for phone service and garbage pickup by 12 to find his average cost per month. This is calculated as follows:

Average cost per month = (98.40 + 79.20) / 12

Average cost per month = 177.60 / 12

Average cost per month = $14.80

Therefore, Mr. Henderson's average cost per month for phone service and garbage pickup last year was $14.80. This means that, on average, he paid about $14.80 per month for these two services.

The y-intercept of the given line is 7/9.

Step-by-step explanation:

The y-intercept of a line is the point where the line crosses the y-axis.

So, to find the point where the line crosses the y-axis we must do x=0.

By substituting x=0 in the following equation, we get

=> 9y + 4(0) = 7

=> 9y = 7

=> y = 7/9

Hence, y = 7/9 is the y-intercept of the given line.

Finding line J's slope is the first step.The simplest approach to achieve this is to change the equation's format to y=mx+b, where m represents the slope.

9x-y=10

Take 9x off of both sides.

9x-y-9x=10-9x

Simpllify -y=-9x+10

Divide both sides by (-9x+10)-1, or -1 -y/-1.

Simplify y=9x-10

m=-1/9.

The notation (x1,y1) y-y1=m(x-x1) y-1=-1/9(x- -8) which reduces to y-1=-1/9(x+8)

y-1=-1/9x-8/9

then multiply both sides by 1.

y-1+1=-1/9x-8/9+9/9

Given that WXZ and YXZ are congruent based on side-angle-side congruency, we can prove the theorem that states "A point on the perpendicular bisector of a line segment is equidistant from the segment’s endpoints." This theorem is often referred to as the "Perpendicular Bisector Theorem."

The required details for "Perpendicular Bisector Theorem" in given paragraph

The Perpendicular Bisector Theorem states that if a point is on the perpendicular bisector of a line segment, then it is equidistant from the segment's endpoints. This means that if we draw a line through a point that is perpendicular to a line segment, and that line passes through the midpoint of the segment, then the point is equidistant from the endpoints of the segment. In this case, we are given that line L is the perpendicular bisector of segment WY, and that Z is a point on L. We are also told that WXZ and YXZ are congruent based on side-angle-side congruency. Since WXZ and YXZ are congruent, it follows that WX and YX are congruent and that WZ and YZ are congruent. This means that the distances from Z to W and Y are equal, so Z is equidistant from W and Y.

Therefore, we can conclude that Z is a point on the perpendicular bisector of segment WY, and the Perpendicular Bisector Theorem is proved. The answer is C. "A point on the perpendicular bisector of a line segment is equidistant from the segment’s endpoints."

The Pythagoras theorem is a mathematical law that states that the sum of squares of the lengths of the two short sides of the right triangle is equal to the square of the length of the hypotenuse.

According to the given question:

∠S and ∠Q are right angles in RSTQ quadrilateral.

RTS and RTQ are right angled triangles.

Applying Pythagorean theorem on both the triangles

sin 35° = b + 60 / RT ⇒ RT = b + 60 / sin 35°

sin 35° = 4b / RT ⇒ RT = 4b / sin 35°

Since RT is common in both equations

b + 60 / sin 35° = 4b / sin 35°

b + 60 = 4b

The Distance from bottom of lamppost is 57.142 ft.

Triangles with the same shape but different sizes are called similar triangles. Examples of similar objects include squares with any side length and all equilateral triangles. To put it another way, if two triangles are similar, their angles are the same and their sides are the same size. The "~" symbol indicates the triangular resemblance here.

Given the height of lamp post is 20 ft

height of man is 6 ft

man walking away with speed of 5 ft per sec

distance covered 8 sec is 8 x 5 = 40 ft

let us consider a triangle ΔABC and consider the triangle with man ΔDEC

which is inside ΔABC as shown in figure,

AB = 20 ft, DE = 5 ft and AD = 40 ft

consider   ΔABC and ΔDEC

∠BAC = ∠EDC = 90⁰

∠BCA = ∠ECD = common angle

so    ΔABC ~ ΔDEC by (AA property)

according to similar triangles

AB/DE = AC/DC

let DC be x and AC is 40 + x

substitute the values

20/6 = (40 + x)/x

20x = (40 + x)6

20x = 240 + 6x

14x = 240

x = 17.142ft

AC = AD + DC = 40 + 17.142 = 57.142 ft

What is an isosceles triangle ?

A triangle with two equal-length sides is known as an isosceles triangle (/assliz/). The term "equilateral triangle" can refer to a shape with either exactly two sides that are the same length or at least two sides that are the same length, with the latter definition containing the equilateral triangle as an exception.

Let the vertex angle to be 'x'

So, according to the question, the measure of the base angels in an isosceles triangle is 8 less than 3 times the measure of a vertex angle

    So, Base angles = (3 × vertex angle) - 8

We know that sum of all angles of a triangle is 180° and the base angles of an isosceles triangle are equal.

∴ Base angles + vertex angle = 180°

  (3 × vertex angle) - 8  + x = 180°

  3x - 8 + x = 180°

  4x = 188°

  x = 47°

∴ The vertex angle is 47° and,

Base angles =  (3 × vertex angle) - 8  

                     = 3 × 47 - 8

                     = 141 - 8
