What is the slope of the line that passes through the points (-8, 12) and
(4, 6)?

Answer:

a) y = (x + 1)^2 - 3

b) minimum

c) (-1, -3)

Step by step:

We start with the equation:

y = x^2 + 2*x - 2

First, we want to complete the square to write the equation in the vertex form.

y = (x - h)^2 + k

Such that the vertex is (h, k)

To complete the square, we can write this as:

y = x^2 + 2*1*x - 2

Now we can add and subtract 1

y = x^2 + 2*1*x + 1 - 1 - 2

y = (x^2 + 2*1*x + 1) - 3

The thing inside the parentheses can be written as:

x^2 + 2*1*x + 1 = (x + 1)^2

Then the quadratic equation will be written as:

y = (x + 1)^2 - 3

This is the vertex form.

b) Now we want to know if the vertex is a minimum or a maximum.

Remember that the leading coefficient tells use if the graph of the function opens up or down.

If the leading coefficient is positive, the graph opens up (then the vertex is a minimum)

If the leading coefficient is negative, the graph opens down (then the vertex is a maximum)

In this case, we can write:

y = 1*(x + 1)^2 - 3

The leading coefficient is 1, positive.

Then the vertex is a minimum.

c) The coordinates of the vertex are:

Remember that in the vertex form:

y = (x - h)^2 + k

the vertex is (h, k)

Then the vertex of our equation is:

(-1, - 3)

The amount of money owned by JIm is $9

From the question, we have the following parameters that can be used in our computation:

The ratio of the amount owned by Tim tohe ratio of the amount owned by Jim is 6 : 1

This means that

Tim : Jim = 6 : 1

Also from the question, we have

Tim gets $54

This means that

Tim = 54

Substitute the known values in the above equation, so, we have the following representation

54 : Jim = 6 : 1

Multiply by 9

54 : Jim = 54 : 9

So, we have

Jim = 9

Hence, the amount is $9

C. Last week it rained every day in San Antonio, Texas

Step-by-step explanation:

Climate is the long-term pattern of weather and temperature. The third answer does not talk about the weather of San Antonio from a long-term perspective, instead, it only discusses a week. The climate of San Antonio should refer to the rain patterns of multiple years, not days.

Answer:

64 + 28 = 92

Step-by-step explanation:

Split the figure in half creating two triangles and a square.

length and width for the square would be 8ft and 8ft. Multiply both for 64 to be the area.

7ft and 4ft are the height and base for the triangles.

In this case, just multiple 7 and 4 because normally you would need to divide the product by 2 however since there are two triangles it negates the step.

Answer:

92ft^2

Step-by-step explanation:

you have to find the are of the triangle and subtract it from the area of the rectangle.

area of the triangle is 28ft^2

area of the rectangle is 120ft^2

120-28 =  92

The range of a sample data collected by a researcher is 10 . So, correct answer is option (C).

Range of a sample data is calculated by using the formula to determine the difference between the highest and lowest value in sample set of values.

R = Highest Value (H) - Lowest Value (L)

Range Formula, R = H - L

Where, R --> range

H --> the highest value

L --> the lowest value

We have, a reaseacher collected a sample data .

Sample data values are following,

3 5 12 3 2

The mean of sample data = 5

Range of sample data = highest data value - lowest data value

There is highgest data value = 12

and lowest data value = 2

Range = 12 - 2 = 10

So, the required range of sample data is 10.

Three straight sides and three angles make up the shape of a triangle. The angles of a triangle can either be acute, right, or obtuse. An angle with three acute angles is a triangle where all three angles measure less than 90 degrees.

A triangle is a three-sided shape with three angles. The sum of the internal angles of a triangle is always 180 degrees. An angle is the amount of turn or change in direction between two lines. There are three types of angles, acute, right and obtuse. An acute angle is an angle which measures less than 90 degrees. A right angle is an angle which measures exactly 90 degrees, and an obtuse angle is an angle which measures more than 90 degrees. Therefore, an angle with three acute angles is a triangle where all three angles measure less than 90 degrees. A triangle with three acute angles is also known as an acute triangle. All three angles must add up to 180 degrees, so the measure of each angle must be less than 60 degrees.

Answer:

x = - 2, x = 1

Step-by-step explanation:

Given

f(x) = [tex]\frac{x}{(x+2)(x-1)}[/tex]

The denominator cannot be zero as this would make f(x) undefined.

Equating the denominator to zero and solving for x gives the values that x cannot be and if the numerator is non zero for these values then they are vertical asymptotes.

(x + 2)(x - 1) = 0

x + 2 = 0 ⇒ x = - 2

x - 1 = 0 ⇒ x = 1

Vertical asymptotes occur at x = - 2 and x = 1

Answer:

x = 72 degrees

y = 9.125 cm

Step-by-step explanation:

the sum of degrees of all angles in a triangle is 180.

because the triangles are similar, all the angles must be the same in both. and the side lengths of one triangle must all have the same scaling factor compared to the other triangle.

the similarity tends is that the angle at E is the same as at B (48 degrees). so, then the angles at C are 60 degrees. that leaves for the angle at D (x) 180 - 60 - 48 = 72

BC (8) is scaled to CE (10) by the factor 10/8 = 5/4

so, y must have the same scaling factor in relation to AB (7.3)

y = 7.3 × 5/4 = 9.125

Answer:

Cost price = R.S 20

Sales price = R.S 22

Step-by-step explanation:

Given:

Sales price of an article = R.S 23

Profit = 15%

Find:

Cost price

Sales price if profit is 10%

Computation:

Profit% = [(Sales price - Cost price) / Cost price]100

15 = [(23-cp)/cp]100

15cp = 2,300 - 100cp

115cp = 2,300

Cost price = R.S 20

Sales price if profit is 10%

Sales price = Cost price + Profit

Sales price = 20 + 10%[20]

Sales price = 20 + 2

Sales price = R.S 22

There are basically 6 types of angles are there which are acute, obtuse, right, straight, reflex and complete angles.

If an angle is less than 90 degrees, it is known as an acute angle. If an angle is more than 90 degrees, then it is called an obtuse angle. If an angle is exactly 90 degrees, then it is called the right angle.

If an angle is precisely 180 degrees, then it is called a straight angle. If the angle is more than 180 degrees but less than 270 degrees, it is known as a reflex angle. A full 360-degree angle is called a complete angle.

The value of each trigonometric ratio is given by :

sin A = 5/13 , cos A = 12/13, tan A = 5 / 12

cosec A = 13 /5 , sec A = 13/12 , cot A = 12 /5.

As given in the question,

Let us consider a triangle be ABC,

Figure is attached.

Side length is given by:

AC = 39

AB = 36

BC = 15

AC represents the longest side

( 36 )² + (15)² = (39)²

⇒AB² + BC² = AC²

By Pythagorean triplets ABC is right angled triangle.

All trigonometric ratio with respect to angle A is given by :

sin A = BC / AC

        = 15/39

        = 5/13

cos A = AB / AC

         = 36 /39

         = 12 /13

tan A = BC / AB

         = 5 /12

cosec A = 1/ sin A

              = 13 /5

sec A = 1/ cos A

         = 13 /12

cot A = 1 / tan A

         = 12 /5

Therefore , the value of all six trigonometric ratio is equal to

sin A = 5/13 , cos A = 12/13, tan A = 5 / 12

cosec A = 13 /5 , sec A = 13/12 , cot A = 12 /5.
