Answer:

B) is false

Explanation:

A triangle canot have 2 abtuse angles and one acute angle.

Answer:

B is false

Step-by-step explanation:

a is true because an equilateral triangle has three acute angles (60 degrees)

c is true because an iscoceles triangle can be drawn with one obtuse angle and two acute angles.

d is true because a right angled triangle can be drawn with one right angle  and two acute angles.

b is false because neither an equilateral, iscoceles, right-angled, or scalene triangle can be drawn with two obtuse angles.

Complete the square of a quadratic equation by identifying the middle term, taking half, squaring, adding, and rewriting as a perfect square trinomial. Therefore, completing the square for the equation m² - 3m + __ results in (m - 3/2)².

To complete the square for the quadratic equation m² - 3m + __, we need to follow these steps:

Step 1: Identify the coefficient of the middle term, which is -3 in this case.
Step 2: Take half of the coefficient, which is -3/2.
Step 3: Square the result, (-3/2)² = 9/4.
Step 4: Add the squared result to both sides of the equation: m² - 3m + 9/4.
Step 5: Rewrite the equation as a perfect square trinomial: (m - 3/2)².

Therefore, completing the square for the equation m² - 3m + __ results in (m - 3/2)².

Answer:

x = -5 or x= 2

Step-by-step explanation:

|-4x-6| = 14

There are two solutions, one positive and one negative

-4x-6 = 14       -4x-6 = -14

Add 6 to each side

-4x-6+6 = 14+6       -4x-6+6 = -14+6

-4x = 20                      -4x = -8

Divide by -4

-4x/-4 = 20/-4               -4x/-4 = -8/-4

x = -5                                x = 2

Now we have to,

find the required value of x.

Given that,

→ |-4x -6| = 14

Let's find the both positive value and negative value,

===================

→ -4x -6 = 14

→ -4x = 14 + 6

→ -4x = 20

→ x = 20/-4

→ [x = -5]

===================

→ -4x -6 = -14

→ -4x = -14 + 6

→ -4x = -8

→ x = -8/-4

→ x = 8/4

→ [x = 2]

===================

Therefore, x is -5 (or) 2 is the answer.

base times height is the formula

Answer:

m∠QPS = 112

Step-by-step explanation:

Shape PQRS is a cyclic quadrilateral as every vertex of the quadrilateral touches the circumference of the circle.

The opposite angles in a cyclic quadrilateral add up to 180°.

⇒ m∠QPS + m∠QRS = 180°

⇒ m∠QPS + 68° = 180°

⇒ m∠QPS = 180° - 68°

⇒ m∠QPS = 112°

Answer:

B. AC = 22, BC = 22, AB = 44

C. AC = 30, BC = 30, AB = 60

Step-by-step explanation:

B.

\( radius \: \overline {OR} \perp chord \: \overline {AB} \) at C. (given)

\( \therefore AC = BC\) (perpendicular dropped from the center of the circle to the chord bisects the chord)

\( \therefore 2x - 6 = x + 8\)

\( \therefore 2x - x= 6 + 8\)

\( \therefore x= 14\)

\( AC = 2x-6=2(14)-6=28-6= 22\)

\( BC= x + 8=14 + 8= 22\)

AB = AC + BC = 22 + 22 = 44

C.

\( radius \: \overline {OR} \perp chord \: \overline {AB} \) at C. (given)

\( \therefore BC = AC\) (perpendicular dropped from the center of the circle to the chord bisects the chord)

\( \therefore 7x-5=4x+10 \)

\( \therefore 7x - 4x= 5 + 10\)

\( \therefore 3x= 15\)

\( \therefore x= \frac{15}{3}\)

\( \therefore x= 5\)

\( AC = 4x+10=4(5)+10=20+10= 30\)

\( BC= 7x - 5=7(5)-5=35-5= 30\)

AB = AC + BC = 30 + 30 = 60

Substitute 8 for x in the equation to ontain the value of f(8).

So answer is f(8)=79.

Given:

The number of pages she has left to read is 276−35d, where d represents the number of days she has been reading.

To find:

The explanation of each part of the expression.

Solution:

The given expression is

\(276-35d\)

Here, 276 is initial number of pages or total number of pages.

d is number of days she has been reading.

-35 represents the remaining pages decreased by 35 per day.

35d is number of pages she reads in d days she has been reading.

Therefore, total number of pages is 276 and number of pages she reads each day is 35.

At time t = 0, the capacitor in the circuit is charged to its maximum charge, qmax, and the circuit has zero current.

At t = 0, the capacitor in the circuit is fully charged, which means it has accumulated its maximum charge, qmax. The capacitor acts as a temporary energy storage device in the circuit. When the capacitor is fully charged, it contains potential energy. The charge on the capacitor creates an electric field, which opposes the flow of current through the circuit.

Since the capacitor is fully charged at t = 0, it resists any change in the current. Therefore, the circuit has zero current flowing through it. As time progresses, the capacitor will start to discharge, releasing the stored energy and allowing the current to flow. The discharge process is governed by the relationship between the voltage across the capacitor, the capacitance of the capacitor, and the resistance in the circuit.

Finally, at t = 0, the capacitor in the circuit is charged to its maximum capacity, qmax, and the circuit has zero current flowing through it.

1)  The number of gallons of soapy water that are in Elianni's bucket are; 1.5 gallons

2) The number of more quarts that it can hold is; 14 more quarts

Elianni puts 12 pints of soapy water in the bucket to wash her blue Hondi. From conversion factors, we know that;

1 pint = 1/8 gallon

Thus;

12 pints = 12 * (1/8)

12 pints =  (12/8) gallons

= 3/2 = 1.5 gallons.

Due to the fact that the bucket is 5 gallon capacity, It can hold:

5 - 1.5 = 3.5 gallons more.

But from conversion factors, we know that;

1 gallon = 4 quarts.

Thus;

3.5 gallons = 3.5 * 4

= 14 quarts more.

Step-by-step explanation:

The most appropriate replication method for Kia Darby's study of public schools in Appalachia is to compare three schools from the same region, as opposed to replicating Dr. Shamus Khan's methodology of studying an elite boarding school.

Replication is an important aspect of scientific research that allows for the verification of research findings and the strengthening of scientific knowledge. However, it is essential to choose an appropriate replication method that is aligned with the research question, context, and variables.

Dr. Shamus Khan's study of an elite boarding school cannot be replicated in the context of public schools in Appalachia. The educational setting, student demographics, and institutional resources are vastly different, making it challenging to compare and generalize findings.

Comparing three public schools from the same region is a more appropriate replication method for Kia Darby's study. This approach allows for the control of confounding variables and the examination of similarities and differences in school performance, culture, and outcomes. Additionally, Kia could gather statistical data from archives, conduct interviews with school personnel and students, and observe classroom interactions to gain a comprehensive understanding of the research question.

Overall, replication is a crucial aspect of scientific research, and researchers should carefully consider the replication method that aligns with their research question and context.
