To solve the quadratic equation, factor the expression and then clear x from each of the factors obtained.

This equation has 2 solutions which are -5 and -1.

The ratio of the perimeters of two similar shapes is equal to the ratio of their corresponding sides, then, by taking the top sides of these figures we can express the following ratio

18 : 24

by dividing both numbers by 2, we get:

9 : 12

Dividing by 3:

3 : 4

Then the ratio of their perimeters equals 3 : 4

The average number of persons admitted in one year is X/5.

What is average number?

Average By adding a collection of numbers, dividing by their count, and then summing the results, the arithmetic mean is determined.

If X persons are admitted in last 5 years in a hospital.

Then we get the average value of admitted persons are X/5 per year.

If Y persons are recovered in last 5 years in a hospital.

Then we get the average value of recovered persons are Y/5 per year.

Therefore, the average number of persons admitted in one year is X/5.

The class interval of the median is 1 ≤ x ≤ 2 and the mean of the distribution is 1.8

From the question, we have

Number of students = 30

This represents the total frequency

So, we have

Total frequency = 30

The median position is then calculated as

Median = (Total frequency + 1)/2

Substitute the known values in the above equation

So, we have

Median = (30 + 1)/2

Evaluate

Median = 15.5th

The 15.5th element is located in the second class

i.e. the class with the interval 1 ≤ x ≤ 2

So, the class interval in this case is 1 ≤ x ≤ 2

To do this, we start by calculating the average of the class interval

This is represented as

0 ≤ x ≤ 1 ⇒ 0.5

1 ≤ x ≤ 2 ⇒ 1.5

2 ≤ x ≤ 3 ⇒ 2.5

3 ≤ x ≤ 4 ⇒ 3.5

So, we have

x        f

0.5   6

1.5    13

2.5    7

3.5    4

The mean is calculated as

Mean = ∑fx/∑f

So, we have

Mean = (0.5 * 6 + 1.5 * 13 + 2.5 * 7 + 3.5 * 4)/30

Evaluate

Mean = 1.8

Hence, the mean value is 1.8

3) The given inequality is

The inequality symbol is that of less than. Since it has an equal to sign attached, then, the meaning is h is less than or equal to 9. In words, h is at most 9, no more than 9.

The domain of a function is the possible values of "t" that the given function can take.

Since the variable "t" is in the denominator, the denominator cannot be equal to zero because it would make the function undefined.

Hence, t - 4 must be greater than zero. For t - 4 to be greater than zero, the value of t must be greater than 4.

In addition, since the variable is inside the radical sign, then the function itself cannot be negative.

Hence, the domain of this function must be greater than 4. In interval notation, it is (4, ∞).

Answer:

  y = 4/9x +10/3

Step-by-step explanation:

You want the slope-intercept equation of the line through point (-3, 2) that is perpendicular to the line y = -9/4x +1.

The slope-intercept form of the equation for a line is ...

  y = mx + b . . . . . . m is the slope, b is the y-intercept

In order to write the desired equation, we need to know the desired slope and the y-intercept that makes the line go through the given point.

The slope of the perpendicular line is the opposite reciprocal of the slope of the given line. The given line equation is in slope-intercept form, so the coefficient of x is the slope of it: -9/4.

The slope of the perpendicular line is the opposite reciprocal of this:

  m = -1/(-9/4) = 4/9

Solving the slope-intercept form equation for b, we find ...

  b = y - mx

Using the values of x and y for the given point, and the slope we just found, we have ...

  b = 2 -(4/9)(-3) = 2 +4/3 = 10/3

The slope-intercept equation for a line with slope 4/9 and y-intercept 2/3 is ...

  y = 4/9x +10/3

__

Additional comment

It can also be useful to start from the point-slope equation:

  y -k = m(x -h) . . . . . line with slope m through point (h, k)

Your line is ...

  y -2 = 4/9(x +3) . . . . . . use m=opposite reciprocal of -9/4; (h, k) = (-3, 2)

  y = 4/9x +(4/9)(3) +2 = 4/9x +10/3 . . . . . . add 2 and simplify

The quadrilateral has diagonals that are both congruent and perpendicular is square.

The correct option is (d)

Answer:

Its A

Step-by-step explanation:

A graph is proportional if the line intersects at the origin (0, 0)

and the y-intercept will always equal to 0

Since y-intercept is the value of y when x =0, and it passes the origin at x = 0, y= 0.

The answer is 0

Answer:

Hughes Family: 40 L/ hour
Gonzalez family: 25L/hour

Step-by-step explanation:

Let us use the following variables to denote the output rates for each sprinkler.

Let H = water output rate for the Hughes family

Let G = water output rate for the Gonzalez family

(I am using H ang G rather than the traditionally used X and Y to easily identify which rate belongs to which family)

The general equation for the volume of water outputted, V,  in time h hours at a rate of r per hour is
V = r x h

Given r

Using this fact
Water Output for Hughes family at rate H for 15 hours = 15H

Water Output for Gonzalez family at rate G for 35 hours = 35 G

The total of both outputs = 1475

That gives us one equation
15H + 35G = 1475    [1]

We are given the combined rate as 65 L per hour
Sum of the two rates = combined rate

H + G = 65   [2]

The doubling time for the general price levels in the eonomy given the average annual inflation rate is 18 years.

Inflation is a period where the general price levels in an economy rise persistently. When there is an inflation, the prices of goods and services increase. Inflation can either be as a result of an increase in the cost of production or an increase in the demand of a good.

The rule of 72 can be used to determine the doubling time. The rule of 72 is a rule of thumb that determines the number of years it would take an investment to double given its rate of growth.

The rule of 72 = 72 / inflation rate

72 / 4 = 18 years

Given:

Percent of participants that used triangles shape = 80% = 0.80

The triangles shaped won their trials 16% of the time = 0.16

The other shaped plane won their trials 36% of the time = 0.36

Thus, we have:

Percent of participants who used other shapes = 100% - 80% = 20% = 0.20

Amount of time the triangle shaped plane lost = 100% - 16% =84% = 0.84

Amount of time the other shaped plane lost = 100% - 36% = 64% = 0.64

Solution:

Let b represent the cost of 1 banana

Let p represent the cost of 1 pear

From the first statement, The cost of 4 bananas and 6 pears is $1.68

4b + 6p = 1.68 ----------------------------equation (1)

From the second statement, Nine bananas and 2 pears cost $1.48

9b + 2p = 1.48 -----------------------------equation (2)

Solve both equations simultaneously

4b + 6p = 1.68 ----------------------------equation (1)

9b + 2p = 1.48 -----------------------------equation (2)

Multiply equation (2) by 3 to eliminate p

27b + 6p = 4.44

4b + 6p = 1.68

Subtract both equatuions above

23b = 2.76

b = 2.76/23

b= 0.12

Substitute b = 0.12 into equation (1)

9b + 2p = 1.48

9(0.12) + 2p = 1.48

1.08 + 2p = 1.48

2p = 1.48 - 1.08

2p = 0.4

p = 0.4/2

p = 0.2

Hence, the cost of each banana is $0.12 while the cost of each pear is $0.2

The area of the right angled triangle as well as that of the isosceles triangle is calculated as

Area = 1/2 (b * h)

The explanation is logical, observe the right angled triangle (the one on the left) and you'll see that the length covered by the height (labelled as h) is not the entire width covered by the base (labelled as b) unlike what you have in a rectangle or square. Its only logical to multiply the base by half of the height, otherwise you might end up calculating the area of a rectangle.

That applies to all triangles in general, the area is calculated as

The line θ=π/2 is the vertical line in the polar grid, the polar axis is the horizontal line and the pole is the center of coordinates. Now let's analyze the symmetries:

If the grpah is symmetric with respect to θ=π/2 then the graph at the left of this line has to be the mirrored image of the graph at the right side. This is the case of this graph so it does have symmetry with respect to θ=π/2.

For the polar axis is the same, the graph above the axis has to be the mirrored image of that below the axis. However in this case we have two "petals" above the polar axis and one below so the upper part is not the mirrored version of the lower part so it has no symmetry with respect to this axis.

For the pole we must rotate the graph 180°. If the graph remains unchanged then it is symmetric with respect to it. In this case if we rotate the graph 180° the lower petal ends up in the opposite direction so the graph changes after a 180° rotation and it has no symmetry with respect to the pole.

Then the only type of symmetry is with respect to the line θ=π/2 and the answer is option a.
