Answer:

At any given moment, the red ant's coordinates may be written as (a, a) where a > 0. The red ant's distance from the anthill is $a\sqrt{2}$ . The black ant's coordinates may be written as (-a, -a) and the black ant's distance from the anthill is $a\sqrt{2}$ . This shows that at any given moment, both ants are $a\sqrt{2}$ units from the anthill.

Step-by-step explanation:

Given:

red ant's coordinates written as (a,a)

black ant's coordinates are written as (-a, -a)

To find:

The distance of red and black ants from anthill

Solution:

Compute the distance of red ant from the anthill using distance formula

d (red ant) = $\sqrt{(a-0)^{2}+ (a-0)^{2}}$

= $\sqrt{a^{2} + a^{2} }$

= $\sqrt{2a^{2} }$

= $a\sqrt{2}$

So distance of red ant from anthill is $a\sqrt{2}$

Compute the distance of black ant from the anthill using distance formula

d (black ant) = $\sqrt{(-a-0)^{2}+ (-a-0)^{2}}$

= $\sqrt{(-a)^{2} + (-a)^{2} }$

= $\sqrt{a^{2} + a^{2} }$

= $\sqrt{2a^{2} }$

= $a\sqrt{2}$

So distance of black ant from anthill is $a\sqrt{2}$

Hence both ants are $a\sqrt{2}$ units from the anthill.

Answer:

I don't know how many terms you need so...

2, 5, 8, 11, 14, 17, 20, 23, 26, 29, 32, 35, 38, 41, 44, 47, 50, 53, 56, 59, 62, 65, 68, 71, 74, 77, 80, 83, 86, 89, 92, 95, 98, 101, 104, 107, 110

These are the next 35 terms past 5. Hope this answers whatever question you had

Answer:

m<-2

Step-by-step explanation:

-4m-3.65>4.35

-4m>4.35+3.65

-4m>8

4m<-8 (the greater than or less than sign flips when you multiply or divide by the - sign)

m<-2 (divide both sides by 4)

Given points A(−2,0), B(−5,3), C(−9,−1), P(7,6), Q(4,0), and R(−4,4), which of the following proves that △ABC~△PQR?

UNO [17]

Based on the SSS similarity theorem, △ABC ~ △PQR because AB/PQ = BC/QR = CA/RP = √2/√5 = √10/5 (option D).

<h3>The SSS Similarity Theorem</h3>

Two triangles having three pairs of sides that are proportional can be proven to be similar by the SSS similarity theorem.

If the triangle ABC and triangle PQR are similar, their corresponding sides will be proportional, meaning that: AB/PQ = BC/QR = CA/RP.

Therefore, using the distance formula, $d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$ , the sides of each triangle is found.

Therefore, it shows that:

AB/PQ = BC/QR = CA/RP = √2/√5 = √10/5

Therefore, based on the SSS similarity theorem, △ABC ~ △PQR because AB/PQ = BC/QR = CA/RP = √2/√5 = √10/5 (option D).
