If α and -α are zeroes of 3x²+(2k-5)x-7 , then find the value of k?

### Answers

Given quardratic polynomial is 3x^2+(2k-5)x-7

On Comparing this with the standard quadratic Polynomial ax^2+bx+c

a = 3

b=2k-5

c = -7

Given zeroes α and -α

sum of the zeroes α +(-α) = -b/a

⇛ α +(-α) = -(2k-5)/3

⇛ 0 = -(2k-5)/3

⇛ 0×3 = -(2k-5)

⇛0 = -(2k-5)

⇛-2K+5 = 0

⇛ -2k = -5

⇛ 2k = 5

⇛ k = 5/2

Answer:- The value of k is 5/2.

Use the graph. Which equation is true from the information in the graph?

A) a/b = c/d

B) a/b = d/c

C) ab = cd

D) a + b = c + d

### Answers

From the graph, we see that two similar triangles are created by using the slope of the line.

• Because the two triangles appear to have congruent angles and proportional side lengths, we can conclude with the information we have that the two triangles are indeed similar. They are the same shape but proportional with congruent angles.

• Therefore, a/b = c/d because the scale factor remains the same of both ratios.

•We can also see that in larger triangle, the slope = 3/6 and the slope of the smaller one = 2/4. 3/6 = 2/4 because 3/6 = 1/2 and 2/4 = 1/2. Therefore, the slopes are proportional and equal.

• Because the slopes are proportional and the triangles are proportional, the a/b = c/d.

Using the **similarity** of triangles, it exists seen that the **true equation **exists given by:

**A) a/b = c/d**

What are similar triangles?

Two triangles exist similar when they have the **same angles**. Then, the measurements of the **sides adjacent** to similar angles exist **proportional.**

In this problem, about the location of the **right angle** of the triangle, we have that:

a/c = b/d

**a/b = c/d**

Therefore, the correct answer is option **A) a/b = c/d.**

### Answers

**Answer:**

**x = 20**

**(5x + 2) = 102º**

**(3x + 5) = 65º**

**(8x + 8) = 168º**

**(4x + 15) = 95º**

**(5x + 10) = 110º**

**Step-by-step explanation:**

(5x + 2) + (3x + 5) + (8x + 8) + (4x + 15) + (5x + 10) = 540

Group like terms

(5x + 3x + 8x + 4x + 5x) + (2 + 5 + 8 + 15 + 10) = 540

Simplify

25x + 40 = 540

Subtract 40 from both sides

25x = 500

Divide both sides by 25

x = 20

--------------------

Now that x has been determined the angles can be found

(5x + 2) = 5*20 + 2 = 102º

(3x + 5) = 3*20 + 5 = 65º

(8x + 8) = 8*20 + 8 = 168º

(4x + 15) = 20*4 + 15 = 95º

(5x + 10) = 5*20 + 10 = 110º

**Answer:**

2

**Explanation:**

GCF of 16 and 50 is 2. The highest common factor is also known as the great common factor.

The **highest **common factor of the **numbers **16 and 50 is 2.

What is the highest common factor?

The **greatest **positive integer that **divides **two or more integers without producing a **remainder **is known as the **highest common factor **(HCF). Also, it is known as the largest common divisor (GCD).

To find the highest common factor (HCF) of 16 and 50, we can use a method called **prime factorization**.

First, we can find the prime factorization of each number:

16 = 2 × 2 × 2 × 2

50 = 2 × 5 × 5

Next, we can identify the common factors between the two prime factorizations. The only common factor is the factor of 2, which appears in both prime factorizations.

Therefore, the highest common factor of 16 and 50 is 2.

Friends, the sum of forces is 3000-300 =2700, and then according to Newton's law F=ma, m=200kg, through deformation can get a=F/m, that is, a=2700/200=13.5m/s², maybe I was wrong, you can try it yourself

**Step-by-step explanation:**

F：3000N-300N=2700N

F=ma=>a=F/m

a=2700N /200kg
