1.  (a)The  vertex of the  function [tex]y=x^{2} +5x-7[/tex]  is [tex](-\frac{5}{2} ,-\frac{53}{4} )[/tex]

How is the vertex calculated?

In function [tex]y=x^{2} +5x-7[/tex],

a= 1 ,b= 5, c= -7

For a function   [tex]y=ax^{2} +bx+c[/tex]  , where (a≠0),

The vertex is [tex](-\frac{b}{2a} ,\frac{4ac-b^{2} }{4a} )[/tex]

[tex]x_v=-\frac{b}{2a}\\\\ =-\frac{5}{2*1} \\\\=-\frac{5}{2} \\\\\\y_v=\frac{4ac-b^{2} }{4a} \\\\=\frac{4*1*(-7)-(5^{2} )}{4*1}\\\\ =-\frac{53}{4}[/tex]

So, vertex  [tex](-\frac{5}{2} ,-\frac{53}{4} )[/tex] is minimum because a>0

(b)The solutions are [tex](\frac{\sqrt{53} -5}{2},0) (\frac{-5-\sqrt{53} }{2},0)[/tex]

How is the solution calculated?

When a function [tex]y=ax^{2} +bx+c =0[/tex]  where (a≠0),

[tex]x=\frac{-b\pm\sqrt{b^{2} -4ac} }{2a} \\\\x=\frac{-5\pm\sqrt{5^{2} -4(1)(-7)} }{2(1)} \\\\x=\frac{-5\pm\sqrt{53} }{2} \\\\x=\frac{\sqrt{53} -5}{2} , x=\frac{-5-\sqrt{53} }{2} \\\\\text{The solutions are } (\frac{\sqrt{53} -5}{2},0) (\frac{-5-\sqrt{53} }{2},0)[/tex]

2. (a)The  vertex of the  function [tex]y=-x^{2} +3x+8[/tex]  is [tex](\frac{3}{2} ,\frac{41}{4} )[/tex]

How is the vertex calculated?

In function [tex]y=-x^{2} +3x +8[/tex]

a= -1 ,b= 3, c= 8

For a function   [tex]y=ax^{2} +bx+c[/tex]  , where (a≠0),

The vertex is [tex](-\frac{b}{2a} ,\frac{4ac-b^{2} }{4a} )[/tex]

[tex]x_v=-\frac{b}{2a}\\\\ =-\frac{3}{2*(-1)} \\\\=\frac{3}{2} \\\\\\y_v=\frac{4ac-b^{2} }{4a} \\\\=\frac{4*(-1)*(8)-(3^{2} )}{4*(-1)}\\\\ =\frac{41}{4}[/tex]

So, vertex  [tex](\frac{3}{2} ,\frac{41}{4} )[/tex] is maximum because a<0

(b)The solutions are [tex](\frac{3+\sqrt{41} }{2},0) (\frac{3-\sqrt{41} }{2},0)[/tex]

How is the solution calculated?

When a function [tex]y=ax^{2} +bx+c =0[/tex]  where (a≠0),

[tex]x=\frac{-b\pm\sqrt{b^{2} -4ac} }{2a} \\\\x=\frac{-3\pm\sqrt{3^{2} -4(-1)(8)} }{2(-1)} \\\\x=\frac{-3\pm\sqrt{41} }{-2} \\\\x=\frac{3\pm\sqrt{41} }{2}\\\\x=\frac{3-\sqrt{41}}{2} , x=\frac{3+\sqrt{41} }{2} \\\\\text{The solutions are } (\frac{3+\sqrt{41} }{2},0) (\frac{3-\sqrt{41} }{2},0)[/tex]

Fine the average rate of change for f(x) on the interval [-1,3]

Answers

For any function f(x), the average rate of change on the interval [x1,x2] is given by [f(x2) - f(x1)]/(x2-x1)

For f(-1) = 2.5 and f(3) = 40, the average rate of change on the interval [-1,3] is given by:

step 1 - (40 - 2.5)/[3-(-1)] = 37.5/4 = 9.375

step 2 - (37.5)/4

step 3 - Solving the fraction we find that the average rate of change is 9.375 (or 75/8)

right triangle - One of the sides that touches the 90-degree angle constitutes the foundation of a right triangle.

The height of a triangle is measured from its base to its highest point, and in a right triangle, that height can be determined from the side that forms a right angle to the base.

acute triangle - Three sides and three vertices make up the fundamental polygon known as the triangle. It has three sides, which results in three interior angles. An acute angle is one that is between 0° and 90° in length. When all three of the triangle's internal angles are acute, the triangle is said to be acute.

obtuse triangle - In an obtuse triangle, the height or altitude from the acute angles is outside the triangle. To find the height of the obtuse triangle, we extend the base as illustrated.

The slope-intercept form for this linear function is y = 8x + 47.

How to calculate the slope of a line?

Mathematically, the slope of a straight line can be calculated by using this formula;

[tex]Slope,\;m = \frac{Change\;in\;y\;axis}{Change\;in\;x\;axis}\\\\Slope,\;m = \frac{y_2\;-\;y_1}{x_2\;-\;x_1}[/tex]

From the linear function, we have:

Points on x-axis = (-3, 2).

Points on y-axis = (23, -17).

Substituting the given points into the formula, we have;

Slope, m = (-17 - 23)/(2 + 3)

Slope, m = -40/5

Slope, m = -8

Mathematically, the slope-intercept form of a straight line is given by;

y = mx + c

Where:

x and y are the points.m represents the slope.c represents the intercept.

At point (-3, 23), we have:

y = mx + c

23 = 8(-3) + c

23 = -24 + c

c = 23 + 24

c = 47

Therefore, the slope-intercept form is as follows:

y = mx + c

y = 8x + 47

There are two more quarters than dimes and as many nickels as dimes and quarters together. The total amount of money is 3. 75 dollars how many nickels dimes and quarters are there each

Answers

There are two more quarters than dimes and as many nickels as dimes and quarters together. The total amount of money is 3. 75 dollars, then nickels dimes and quarters are there each, D =7 dimes , Q =  9 quarters, and N  =  16 nickels

               

tart by defining the variables for this problem :

Q : number of quarters

D : number of dimes

N : number of nickels

There are two more quarters than dimes so the equation :

Q = D+2

And as many nickels, as quarters and dimes together so the equation :

N = Q+ D

The total amount of money is $3.75  so the equation :

0.25Q + 0.10D + 0.05N =3.75

Solve the following system :

Q = D + 2 (I)

N = Q + D (II)

0.25Q + 0.10D + 0.05N =3.75(III)

In the equation (II)  find Q in terms of N and D :

N = Q + D (II)

Q = N - D (IV)

If  use (I) in (IV) :

Q = N - D

D + 2 = N - D

2D = N - 2

N = 2D + 2 (V)

If use (I) and (V) in (III)

0.25Q + 0.10D + 0.05N =3.75

(0.25) . (D + 2) + 0.10D + (0.05) . (2D + 2) = 3.75

0.25D +0.50 + 0.10D + 0.1D + 0.1 = 3.75

0.45D = 3.75

D = 3.75/ 0.45

D = 7

if D = 7 -----------replacing in (I)

Q = D + 2

Q = 7 + 2

Q   = 9

If  replace this values in (II)

N = Q + D

N = 9 + 7

N = 16

there are D =7 dimes,

                 Q =  9 quarters

                  N  =  16 nickels

Look at the two histograms below. They give you information about the heights of players on two basketball teams, the Tigers and the Panthers. Use the histograms to answer the following questions.

Answers

The most appropriate choice for histogram will be given by-

a) Team tigers has taller players than team panthers

Team panthers has shorter players than team tigers.

b) team tigers have height that vary more.

c) So team panthers have more players about the same height.  

What is histogram?

Histogram is a type of bar graph which makes use of the range of classes in the horizontal x axis and the frequency of classes in the vertical y axis.

Here,

a) The bars in the histogram of team tigers are relatively taller than the bars in the histogram of team panthers. So, team tigers has taller players than team panthers.

The bars in the histogram of team panthers are relatively shorter than the bars in the histogram of team tigers. So, team panthers has shorter players than team tigers.

b) For team tigers, there are no players between 66-69 inches height and, two players between 69-72 inches height and five players between 72-75 inches height. So fluctuations between the heights of two consecutive bars for team tigers is more.

For team panthers, it can be seen that the fluctuation between the heights of heights of two consecutive bars is not that much.

So team tigers have height that vary more.

c) In team panthers, there are one player in 63-66 inches and 69-72 inches, three players in 66-69 inches and 75-78 inches and two players between 72-75 inches and 78-81 inches. So team panthers have more players about the same height.

What does math standard deviation mean?

The standard deviation shows the average level of variability in your dataset. It provides the standard deviation of every statistic. A low standard deviation indicates that values are frequently within a certain distance of the mean, whereas a high standard deviation indicates that values are frequently outside of this range. Consider the information below: 2, 1, 3, 2, 4. The deviations from the mean of the observations will be represented by the average and the sum of squares, which will be 2.4 and 5.2, respectively. This indicates that the standard deviation will be (5.2/5) = 1.01.

If T = 1, then the number T2580 represents 2580 as the right answer. This is the basic rules of linear equation.

What is linear equation?

The first order of equations are linear equations. For lines in the coordinate system, linear equations are defined. It is referred to as a linear equation in one variable when the equation contains a homogeneous variable of degree 1 (i.e., only one variable).

There may be multiple variables in a linear equation. Linear equations in two variables, and so forth, are what the equation is known as if it contains two variables. 2x-3=0, 2y=8, m + 1 = 0, x/2 = 3, x + y = 2, and 3x - y + z = 3 are a few examples of linear equations.
