Answer:

(4, 6)

Step-by-step explanation:

The first quadrant is in the top right, second is in bottom right, third in bottom left, and fourth in top left.

The x-axis is told by the first number listed in the point (#, #), and the y-axis is listed in the second number.

(4, -6) is in the second quadrant and is listed on the graph.

(4, 6) is in the first quadrant and is listed on the graph.

(6, 4) is in the first quadrant and is not listed on the graph.

(-4, 6) is in the fourth quadrant and is not listed on the graph.

(the point in the third quadrant is at the point (-4, -6), which is not listed)

f(0) = 3

Step-by-step explanation:

We will use the first equation, since x = 0

Answer:

a) 24 minutes

b) 20 mph

Step-by-step explanation:

  time= 12 min

         \(\sf = \dfrac{12}{60} \ hour\)

 speed = 60 mph

\(\sf \boxed{distance =speed * time}\)

                \(\sf = 60 * \dfrac{12}{60}\\\\ = 12 \ m\)    

a) Speed = 30 mph

      \(\sf \boxed{time = \dfrac{distance}{speed}}\)

               \(\sf = \dfrac{12}{30}\\\\ = \dfrac{2}{5} \ hour\\\\ = \dfrac{2}{5}*60\\\\= 2 * 12\\\\= 24 \ minutes\)

It will take 24 minutes.

c) time = 36 minutes

           \(\sf = \dfrac{36}{60} \hour\)

 \(\sf \boxed{speed= \dfrac{distance}{time}}\)

            \(\sf = \dfrac{12}{ \dfrac{36}{60}}\\\\\\ = 12* \dfrac{60}{36}\\\\= 20 \ mph\)

Average speed = 20 mph

Ss, variance and the standard deviation for the population of scores is 2.83 and 8 respectively

What is standard deviation and variance?

Standard deviation is a measure of the distribution of statistical data, whereas variance is a measure of how data points differ from the mean. The fundamental distinction between the two is that although the variance is expressed in squared units, the standard deviation is expressed in the same units as the data's mean.

Given,

SS = 40

Variance = 10

Standard Deviation = 3.16

Using Population Variance Formula :

= \(\frac{1}{n}\)∑( x-xbar)²  where i is 1

For the complete solution see the attachment of table

sum ( x - x bar)² = 40

so, variance = 40/5

= 8

standard deviation = \(\sqrt{8}\)

= 2.83

What is a cyclic polygon?

A cyclic polygon is a polygon that can be inscribed inside a circle in such a way that all of its vertices lie on the circumference of the circle. In other words, a cyclic polygon is a polygon that can be circumscribed by a circle.

In a polygon with n sides, the sum of its interior angles is given by the formula: (n - 2) * 180 degrees. Since this polygon is inside a circle, it must be a cyclic polygon, which means that its opposite angles add up to 180 degrees.

We are given that the opposite angles are 23y and 13y, so we can write:

23y + 13y = 180

36y = 180

y = 5

Therefore, the value of y is 5.

The future age is 4 times current age

x+45 = 4x

x≤-8

Step-by-step explanation:

-1/2x ≥ 4

Multiply each side by -2, remembering to flip the inequality

-2*-1/2x≤ 4*-2

x≤-8

Answer:

Step-by-step explanation:

Note: by the rule of order of operations, -1/2x == -1/2*x = -x/2

-x/2 >= 4

-x >= 4*2 = 8

x <= -8

The number line looks like this:

<============================O--------------------------------------

where the circle should be filled and at x= -8

The valid part of the number line is to the left of the circle but INCLUDING the circle (solid dot).

The result is that x = 8 is the smallest positive number such that f(x) surpasses g(x).

An integer is a whole number that may be positive, minus, or zero and is not a percentage. Integer examples include: -5, 1, 5, 8, 97, as well as 3,043. The following figures are examples of non-integer numbers: -1.43, 1 3/4, 3.14,.09, and 5,643.1.

To find the smallest positive integer x for which f(x) exceeds g(x)

we need to set the two functions equal to each other and solve for x:

f(x) = g(x)

-x² + 5x = -10x + 10

Simplifying the equation, we get:

x² + 15x - 10 = 0

Using the quadratic formula, we can solve for x:

x = (-15 ± sqrt(15² - 4(1)(-10))) / (2(1))

x = (-15 ± sqrt(265)) / 2

The two possible solutions are approximately -0.372 and -14.628. Since we are looking for the smallest positive integer solution, we take the ceiling of the positive solution to get x = 8.

Answer:

3/5, 4/5, 3/4

Step-by-step explanation:

First BC is 12 because of the Pythagorean Theorem. I use sohcahtoa to remember. sine is the side opposite of the angle divided by the hypotenuse of the triangle so 12/20 which is 3/5. cosine is adjacent / hypotenuse so 16/20 which is 4/5, and lastly tangent is opposite / adjacent which is 12/16 which is 3/4

The sine, cosine and the tangent of angle should be \(3\div 5, 4\div 5, 3\div 4\).

Here first we determine the BC by applying the Pythagorean Theorem.

\(= 20^2 - 16^2\\\\= 400 - 256\\\\= 144\)

So the BC should be 12

hence, based on this, we can say that The sine, cosine and the tangent of angle should be \(3\div 5, 4\div 5, 3\div 4\).

Answer:

Step-by-step explanation

1. The total cost of the trip for all 16 families is Rs 2,16,352.
2. To find out how much each family paid, we need to divide the total cost by the number of families: Rs 2,16,352 ÷ 16.
3. When we do the division, we get the result: Rs 13,522.

Now let's check if this result is correct:

1. If each family paid Rs 13,522 for the trip, then the total cost for all 16 families would be: 16 × Rs 13,522 = Rs 2,16,352.
2. This is exactly the same as the total cost given in the problem statement.

So we have shown that each family paid **Rs 13,522** for the trip

The number of Wolves are growling is in multiple of  3.

Comparing two amounts of the same units and determining the ratio tells us how much of one quantity is in the other. Two categories can be used to categorize ratios. Part to whole ratio is one, and part to part ratio is the other. The part-to-part ratio shows the relationship between two separate entities or groupings.

Given  The wolves were either howling of growling,

and ratio of the number of howlers to the number of growlers is

8:3 = 8/3

since the ratio tells about the total number of  wolves either howling of growling,

let total Wolves be y

so y = 8x + 3x

where x is the common multiple for both,

so growling wolves are in multiple of 3.
