Given RT below, if S lies on RT such that the
defon

Answer:

(-2, -3)

Step-by-step explanation:

If a segment having extreme ends as (x_1,y_1) and (x_2,y_2) is divided by a point (x, y) in the ratio of m:n,

x = \frac{mx_2+nx_1}{m+n}

y = \frac{my_2+ny_1}{m+n}

Since, a line RT has extreme ends as R(-5, 3) and T(-1, -5) then a point S(x, y) which divides RT in the ratio of 3 : 1 will be,

x = \frac{3(-1)+1(-5)}{3+1}

  = \frac{-8}{4}

  = -2

y = \frac{3(-5)+1(3)}{3+1}

  = -\frac{12}{4}

  = -3

Therefore, coordinates of the point S will be (-2, -3).

You measure the volume of a cube at rest to be V0. You then measure the volume of the same cube as it passes you in a direction
Evgen [1.6K]

Answer:

V  =  V₀ / 5

Step-by-step explanation:

At rest V₀ is volume measured of a cube

When an observer measures it at high speed  ( 0.98*c ) the length he measures from outside, if he can looks and measures the two points start and ending points of the parallel edge simultaneously,  is shorther ( such effect is known as Lorentz contraction. In this particular case problem statement  give  γ ≈ 5

γ  =  1  / √( 1 - v²/c²)       γ  =  1  / √1  -( 0.98)c²/c²     γ  =  1  /√1-0,9604

γ  =  1 /√ 1 - 0.9604     γ  =  1 /√0.0396    γ  ≈ 5

As the contraction only occur in the sense of the movement then the volume of the cube would be

V = (edge)²* (edge/5)      or   V  =  V₀ / 5

Rory was with some friends outside an ice cream parlor. He noticed that one out of every four people bought a vanilla cone. He w
suter [353]

Answer:

"Spin the spinner 5 times with 4 equal segments. One of the segment represents vanilla on either the spinner as well as three parts reflect certain flavors" would be the right answer.

Step-by-step explanation:

The actual probability of the given scenario will be:

⇒  (1-\frac{1}{4})^5

⇒  (1-0.25)^5

⇒  (0.75)^5

On solving the power, we get

⇒  (0.237304)

Now on multiplying the above value in 100, we get

⇒  23.73%

Approximately 23.73% chance vanilla was not chosen by either of the five. So that the above is the right answer.

Which of these ordered triples indicates where the plane cuts the x-axis for this equation? 7x +2y +3z =42 A. (14,0,0) B. (7,0,0
pickupchik [31]
My answer is: D. <span>(6,0,0)

Given: 
</span><span> 7x +2y +3z =42

I assumed that the format in the given choices is (x,y,z). So, I substituted each number to its corresponding variable.

A. </span>(14,0,0)  → 7(14) +2(0) +3(0) = 42 → 98 + 0 + 0 ≠ 42  NOT THE ANSWER<span>
B. (7,0,0) </span>→ 7(7) +2(0) +3(0) = 42 → 49 + 0 + 0 ≠ 42 NOT THE ANSWER<span>
C. (21,0,0) </span>→ 7(21) +2(0) +3(0) = 42 → 147 + 0 + 0 ≠ 42 NOT THE ANSWER<span>
D. (6,0,0) </span>→ 7(6) +2(0) +3(0) = 42 → 42 + 0 + 0 = 42 CORRECT ANSWER.


<span>The ordered triples indicated where the plane cuts the x-axis for this equation is D. (6,0,0). </span>
