aksik [14]

Answer:

Neither; see below

Step-by-step explanation:

Your acceleration: $a=\frac{\Delta v}{\Delta t}=\frac{25-0}{25}=1m/s^2$

Your friend's acceleration: $a=\frac{\Delta v}{\Delta t}=\frac{6-0}{6}=1m/s^2$

Therefore, since both you and your friend accelerate at the same rate, neither is faster.

Find the length of the leg(s) of a right triangle, to the nearest hundredth, if both legs are equal and the hypotenuse is 10.

charle [14.2K]

Answer:

7.07 units

Step-by-step explanation:

Use the Pythagorean theorem for the right triangle:

$\text{hypotenuse}^2=\text{leg}_1^2+\text{leg}_2^2,\\ \\c^2=a^2+b^2.$

If a = x, b = x, and c = 10, then

$10^2=x^2+x^2,\\ \\100=2x^2,\\ \\x^2=50,\\ \\x=\sqrt{50}=5\sqrt{2}\approx 7.07\ units.$

How many different ways can four team members from the group of fifteen be lined up for a photograph?

damaskus [11]

Answer:

32760

Step-by-step explanation:

This is a permutation of 15 objects taken 4 at a time. To calculate this, we use the formula:

$_nP_r=\frac{n!}{(n-r)!}$

In our case, n is 15 and r is 4:

$_{15}P_4=\frac{15!}{(15-4)!}=\frac{15!}{11!}=32760$

ryzh [129]

Answer: 1050

Step-by-step explanation:

Number of combinations of selecting r things out of n = $^nC_r=\dfrac{n!}{r!(n-r)!}$

such that $^nC_1=n$

Given: A restaurant menu has 5 kinds of soups, 7kinds of main courses, 6 kinds of desserts, and 5 kinds of drinks.

If a customer randomly selects one item from each of these four categories, then by fundamental counting principle , the number of different outcomes are possible = $^5C_1\times \ ^7C_1\times\ ^6C_1\times\ ^5C_1 =5\times7\times6\times5=1050$

hence, total number of outcomes = 1050
