Write yes if the given set of lengths are side lengths of a right triangle. Otherwise write No
Amiraneli [1.4K]

Answer:

a) Yes

b) No

c) Yes

d) No

e) No

Step-by-step explanation:

Right triangle:

The square of the larger side is equals to the sum of the squares of the smaller sides.

a. 6, 8, 10

6^2 + 8^2 = 36 + 64 = 100 = 10^2

The answer is yes.

b. 8, 15, 16

8^2 + 15^2 = 64 + 225 = 289 \neq 16^2 = 256

So no.

c. 10, 24, 26

10^2 + 24^2 = 100 + 576 = 676 = 26^2

So yes

d. 20, 21, 28

20^2 + 21^2 = 400 + 441 = 841 \neq 28^2 = 784

So no.

e. 9, 35, 41​

9^2 + 35^2 = 81 + 1225 = 1306 \neq 41^2 = 1681

The time is took Tayna to complete different sets of math problems varied directly with the number of problems in the set Tayna'
Vsevolod [243]

Answer:

C

Step-by-step explanation:

time is directly proportional to the number of problems in the set

=> x = ky

k = constant of proportionality

when k = 12

x = 12y

by making y the subject, we divide both sides by 12

=> y = x/12

The co-ordinate of point P is (x+3) and Q is (x-3). Then find d(P,Q). If coordinate of R is (x+2). Find d(Q,R).
kari74 [83]

Answer:

<h2>d(P, Q) = 6</h2><h2>d(Q, R) = 5</h2>

Step-by-step explanation:

The formula of a distance between two points A(a) and B(b):

<h3>d = |b - a|</h3>

We have P(x + 3), Q(x- 3), R(x + 2).

Substitute:

d(P, Q) = |(x - 3) - (x + 3)| = |x - 3 - x - 3| = |-6| = 6

d(Q, R) = |(x + 2) - (x - 3)| = |x + 2 - x - (-3)| = |2 + 3| = |5| = 5
