is the vertex of the parabola. This form can be used to determine the minimum y-
value of the related function. Which is the minimum y-value of
y = 5x2 – 20x + 24?

A: -20
B: 2
C: 4
D: 16

Answer:

x = 88.333

Step-by-step explanation:

Octagon = 1080 degrees

1080 = 2x + x + 143 + 152 + 116 + 125 + 140 + 139 (Clean up the problem)

1080 - 815 = 3x

265 = 3x (Divide each side by 3)

Answer: 33 mph

Step-by-step explanation:

First find out what 40% of 55 is:

= 40% * 55

= 22 mph

This means that the speed reduces by 22 mph inside the city.

The speed inside the city is therefore:

= 55 - 22

= 33 mph

A: look at the graph, find the x axis of 2 and on the y axis 1.

B basically the center

C look for x axis of -4, y axis for 3

D x axis -2, y axis -5

E x axis 1, y axis -3

F Center then go up 4

G x axis -5, y axis 1

All the points A(2, 1), B(0, 0), C(-4, 3), D(-2, -5), E(1, -3), F(0, 4), G(-5, 1), and H (-2, 0) are located on the graph.

Coordinate geometry is the study of geometry using the points in space. Using this, it is possible to find the distance between the points, the dividing line is m:n ratio, finding the mid-point of the line, etc.

The collection includes all locations on the surface of the shape (x, f(x)) that make up a function of f's graph. We may alternatively say that the graph of f is the curve of y = f. (x). As a result, the diagram of an equation is a particular instance of the graphs of functions.

The points are given below.

A(2, 1), B(0, 0), C(-4, 3), D(-2, -5), E(1, -3), F(0, 4), G(-5, 1), and H (-2, 0)

Answer:

0 visits

Step-by-step explanation:

According to the scenario, calculation of the given data are as follows,

Rewards for signing up = 80 points

Reward per visit = 2.5 points

Total points needed = 105

Let, number of visits = x

So, we can calculate number of visits by using following formula,

80 + (2.5 × X) = 105

2.5X = 105 - 80

2.5X = 25

X = 25 ÷ 2.5

X = 10 visits.

Hence, Olivia needs to make 10 visits in order to earn a free movie ticket

Answer:

maximum- (-3,5)

Step-by-step explanation:

Step-by-step explanation:

When lines are perpendicular to each other

multiplying their gradients(m) will equal to - 1

so , m1 × m2 = -1

1st:Find m1

5x+6y= -6

make y the subject,

6y= -5x -6

[tex]y = \frac{ - 5x - 6}{6} [/tex]

y= -5/6x - 1

because y = mx + c

m1 = -5/6

2nd:find m2

-5/6 × m2 = -1

m2 = 6/5

3rd: substitute m2 and the coordinates into y=mx+c

y=mx+c

-1= (6/5)(-2)+c

-1 = -12/5 + c

-5 = -12 + c

-5+12= c

c = 7

4th: substitute m2 and c into y= mx+c to find the equation the line

y =6/5x + 7 (Ans)

As per slope-intercept form, the equation of the line through point (−2,−1) and perpendicular to 5x + 6y = -6 is 5y = 6x + 7.

The slope-intercept form of a straight line is y = mx + c.

Here, 'm' is the slope and 'c' ix the y-intercept of the given line.

The given equation is 5x + 6y = - 6

Therefore, in slope-intercept form, this equation will be:

y = - 5x/6 - 1

Therefore, the slope of this line is m = - 5/6 and the y-intercept is c = - 1.

The required line is perpendicular to the given line.

Therefore, the slope of the required line is

= - 1/m

= 6/5

Again, the required line passes through the point (- 2, - 1).

Therefore, - 1 = - 2(6/5) + c

⇒ c = - 1 + 12/5

⇒ c = 7/5

The equation of the required line is

y = (6/5)x + 7/5

⇒ 5y = 6x + 7

Answer:

Negative integers, or numbers below zero, are still whole numbers- just not positive whole numbers. This should help you.

Step-by-step explanation:

The statement describes values of x and y such that could be an irrational numbers, the value of x is the square root of an integer, and the value of y is an integer greater than zero.

We have given that the value of x and y,

such that could be an irrational number.

An irrational number, any real number that cannot be expressed as the quotient of two integers.

Negative integers, or numbers below zero, are still whole numbers- just not positive whole numbers.

Therefore we can conclude that

The statement  A, C, or D do not show the irrational numbers

because they all are stated as integers,

which cannot be irrational.

Therefore option B is correct.

The value of x is the square root of an integer, and the value of y is an integer greater than zero.

The measures of spread include the range, quartiles and the interquartile range, variance and standard deviation. Let's consider each one by one.

Interquartile Range:

Given the Data -> First Quartile = 2, Third Quartile = 5

Interquartile Range = 5 - 2 = 3

Range: 8 - 1 = 7

Variance:

We start by determining the mean,

[tex]\:1+\:2+\:3+\:3+\:3+\:5+\:8 / 7 = 3.57[/tex]

n = number of numbers in the set

Solving for the sum of squares is a long process, so I will skip over that portion and go right into solving for the variance.

[tex]\sum _{i=1}^n\frac{\left(x_i-\bar{x}\right)^2}{n-1},\\\\=> SS/n - 1\\\\=> 31.714/7 - 1\\=> 5.28571[/tex]

5.3

Standard Deviation

We take the square root of the variance,

[tex]\sqrt{5.28571} = 2.29906[/tex]

2.3

If you are not familiar with variance and standard deviation, just leave it.

Tan(72) = opposite / adjacent

The opposite is the height of the building

The adjacent = 100

Tan 72 = 3.077

Tan (72) = opposite / 100

3.077 = opposite / 100                   Multiply by 100

3.077 * 100 = opposite

opposite = 307.7

opposite rounded = 308
