could 10.3cm 4.4cm and 8.3 cm be the side lengths of a triangle yes or no

Answers

Answer:

No

Step-by-step explanation:

As you probably know, triangles have 3 sides. The longest side is called the hypotenuse. In this case, the hypotenuse is 10.3. Now, you might or might not know the pythagorean theorem, which states that the a² + b² =c ².

In this case, we can say that 4.4 is a and 8.3 is b. Now if we square 4.4 and add it to 8.3 squared, we get 88.25. However, if you square 10.3, you get 106.09. Thus, the values cannot be this way. So, your answer is no.

please help.

Answers

Answer:

Step-by-step explanation:

-2/3(-3b-24) = 2(b+8)

6b/3+48/3 = 2b+16

2b+16 = 2b+16 => equivalent

Is -2/3(-12b-6+9b-18) equivalent to 2(b+8)?

To find out, simplify the left side.

Multiply every term in the parentheses by 2/3.

(8b + 4 - 6b + 12)

Simplify.

(2b + 16)

Factor out 2.

2(b + 8)

We conclude that -2/3(-12b-6+9b-18)

equals 2(b + 8).

According to Pythagorean theorem: a^2+b^2=c^2

49+576=c^2

C^2=625

c=25

Answer:

Step-by-step explanation:

This is a right triangle, so we may apply the Pythagorean Theorem.  The two leg lengths are 7 and 24 respectively, and so the length of the hypotenuse is

Part A: (3, 2)

Part B: 5

Step-by-step explanation:

Point B of the parallelogram is the top right dot on the graph. In order to find its coordinate, we simply trace the dot's trajectory back to the x and y axis accordingly. If we look under the dot we see that its x-axis is 3 and if we look to the left of the dot we see that its y-axis is 2. Therefore, the coordinate of the fourth vertex B is (3, 2)

To calculate the length of side AB we simply count the number of squares between them, which looking at the graph we can see is 5 squares. Therefore the length of AB is 5

if one zero of the following polynomial 8x^2-13x-4k is the reciprocal of the other, then find k

Answers

Answer:

k = -2

Step-by-step explanation:

2 way to solve:

1st: 8x²-13x-4k = 8(x²-(13/8)x-(k/2))

if 2 roots: a and 1/a

8(x-a)(x-1/a) = 8(x²-(13/8)x-(k/2))

x²-(a+1/a)x+1 = x²-(13/8)x-(k/2)

1 = -(k/2)

k = -2

2nd: 2 roots of 8x²-13x-4k      x=(-b±√b²-4ac)/2a

x = (13±√169-4*8*(-4k))/16 = (13±√169+128k)/16

(13+(√169+128k))/16 = 16/ (13-(√169+128k))  ... root1=1/root2

(13+(√169+128k))*(13-(√169+128k)) = 16*16

13² - (√169+128k)² = 256

169-169-128k = 256

-128k = 256

k = -2
