4.

Which term of the a.p.11,8,5,2 is -15

Answer»

ong>Answer:

Correct question

Is −150 a term of the A.P : 11,8,5,2 ?

$\huge{\mathcal{\underline{\green{AnSWEr}}}}$

For this A.P., a = 11 d = a2 − a1 = 8 − 11 = −3 Let −150 be the n TH term of this A.P.

We know that, an = a + (n − 1) d -150

= 11 + (n - 1)(-3) -150

= 11 - 3N + 3 -164 = -3n

n = 164/3

Clearly, n is not an integer.

THEREFORE, - 150 is not a term of this A.P

7.	In triangle abc if ab equal to ac and angle b equal to 65degree then find angle c and angle a
Answer» Given : • AB = AC • Angle B = 65° To Find : • Angle C and angle A SOLUTION : ★ Angle C = Angle B → Angle C = 65° Here angle C is EQUAL to the angle B because Opposite angle of equal sides are always equal. Now, from Angle SUM Property : → ∠A + ∠B + ∠C = 180° → ∠A + 65° + 65° = 180° → ∠A + 130° = 180° → ∠A = 180° - 130° → ∠A = 50° $\therefore$ MEASUREMENT of angle C = 65° and angle A = 50°.

7.

In triangle abc if ab equal to ac and angle b equal to 65degree then find angle c and angle a

Answer»

Given :

• AB = AC

• Angle B = 65°

To Find :

• Angle C and angle A

SOLUTION :

★ Angle C = Angle B

→ Angle C = 65°

Here angle C is EQUAL to the angle B because Opposite angle of equal sides are always equal.

Now, from Angle SUM Property :

→ ∠A + ∠B + ∠C = 180°

→ ∠A + 65° + 65° = 180°

→ ∠A + 130° = 180°

→ ∠A = 180° - 130°

→ ∠A = 50°

$\therefore$ MEASUREMENT of angle C = 65° and angle A = 50°.

Solve the following linear equations by trial and error method

Answer»

ong>ANSWER:

ANS is 3

Step-by-step explanation:

In trial and error method we change the value of x.So LET's try CHANGING the value with different numbers.

we have, 5x-2=13

lets change with first taking 2 in place of x

5(2)-2=13

10-2=8

So as we noticed the value didn't came 13 so we will try with other number.

5(3)-2=13

15-2=13

Thus,we got the same value as GIVEN so 3is the answer.

Answer» ong>Given, The coordinates of the four vertices of the quadrilateral are (8,3) , (7,8) , (2,7) and (3,2). To find, The quadrilateral is a square and the AREA of the square. Solution, We can prove the quadrilateral is a square by showing that the four SIDES are equal and one angle is 90°. Length of AB = ✓(8-7)²+(3-8)² = ✓1+25 = ✓26 units Length of BC = ✓(7-2)²+(8-7)² = ✓25+1 = ✓26 units Length of CD = ✓(2-3)²+(7-2)² = ✓1+25 = ✓26 units Length of AD = ✓(3-8)²+(2-3)² = ✓25+1 = ✓26 units Now, if the angle ABC is 90°, then it's components will satisfy the Pythagoras theorem. Length of AC diagonal = ✓(8-2)²+(3-7)² = ✓36+16 = ✓52 units (AC)² = (✓52)² = 52 units Now, (AB)²+(BC)² = (✓26)²+(✓26)² = 52 units So, (AC)² = (AB)²+(BC)² We can SAY that, the angle ABC is 90° And, ABCD is a square. Area of ABCD = (✓26)² = 26 unit² Hence, it is PROVED that ABCD is a square and it's area is 26 unit².

Prove that the quadrilateral ABCD whose vertices are (8, 3), (7, 8), (2, 7) and (3, 2) taken in order is a square. Also, find its area. Plz friends answer fast I WILL MARK AS BRAINLIEST

Answer»

ong>Given,

The coordinates of the four vertices of the quadrilateral are (8,3) , (7,8) , (2,7) and (3,2).

To find,

The quadrilateral is a square and the AREA of the square.

Solution,

We can prove the quadrilateral is a square by showing that the four SIDES are equal and one angle is 90°.

Length of AB = ✓(8-7)²+(3-8)² = ✓1+25 = ✓26 units

Length of BC = ✓(7-2)²+(8-7)² = ✓25+1 = ✓26 units

Length of CD = ✓(2-3)²+(7-2)² = ✓1+25 = ✓26 units

Length of AD = ✓(3-8)²+(2-3)² = ✓25+1 = ✓26 units

Now, if the angle ABC is 90°, then it's components will satisfy the Pythagoras theorem.

Length of AC diagonal = ✓(8-2)²+(3-7)² = ✓36+16 = ✓52 units

(AC)² = (✓52)² = 52 units

Now,

(AB)²+(BC)² = (✓26)²+(✓26)² = 52 units

So,

(AC)² = (AB)²+(BC)²

We can SAY that, the angle ABC is 90°

And, ABCD is a square.

Area of ABCD = (✓26)² = 26 unit²

Hence, it is PROVED that ABCD is a square and it's area is 26 unit².

25.	A taxi ride costs P40.00 as plug down rate and each additional meter(or a fraction of there of)adds Php4.00 to the fare.Use a function to represent the taxi fare in terms of distance in meters
Answer» ong>Answer: Write a function called taxi_fare that computes the fare of a taxi ride. It takes two inputs: the distance in kilometers (d) and the AMOUNT of WAIT time in minutes (t). The fare is CALCULATED like this: the first km is $5 every additional km is $2 and every minute of waiting is $0.25. Once a km is STARTED, it counts as a WHOLE (Hint: consider the ceil built-in function). The same rule applies to wait times. You can assume that d >0 and t >= 0 but they are not necessarily integers. The function returns the fare in dollars. For example, a 3.5-km ride with 2.25 minutes of wait costs $11.75. Note that loops and if-statements are neither necessary nor allowed.
