A stone fell from the top of a cliff into the ocean.
In the air, it had an average speed of 16 m/s. In the water, it had an average speed of 3 m/s before hitting
the seabed. The total distance from the top of the cliff to the seabed is 127 meters, and the stone's entire
fall took 12 seconds.

Answers

Answer 1

Answer:

down below

Step-by-step explanation:

total distance = sum of velocity * time for both legs of the journey;

let the time taken in air be t

hence time taken in water is 12-t

127 = 16*t + 3(12-t)

127 = 16t + 36 - 3t

127 - 36 = 16t - 3t

91 = 13t

t = 91/13 = 7 seconds

ence time taken in air = 7 seconds

time taken in water is 12 - 7 = 5 seconds

checking; 16*7 + 3*5 = 127 (proven

In an isosceles triangle the base angles are both 32 degrees, find the vertex

Answers

Answer:

116 deg

Step-by-step explanation:

note that an isoceles triangle always have 2 base angles that are equal.

Here we are already given one base angle of 32 deg. It follows that the other base angle must also be 32 deg.

We now have 2 angles of a triangle and we need to find the remaining one. Also recall that all 3 internal angles of a triangle sum to 180 deg. if we let the missing angle be x, then:

base angle + base angle + vertex angle = 180°

or,

32° + 32° + x° = 180°

64° + x = 180 deg

x = 180 - 64

x = 116 deg

A is right , using the exponet property, it turns into [tex]x^{1/5}[/tex] to the 7 power which equal x to the 1.4 th power. Using the product of power, [tex]x^{1/5}[/tex] to the 7th power is the same as 1/5 times 7 which equal 1.4. so b is right .Using the fractioal exponet rule C is also right as 5th root of x to the 7th power is the same as  to the 7 power divided by 5 which 1.4 so c is right

Given a right triangle, find the length of the missing leg given the hypotenuse is 13 cm and the other leg is 5 cm. (Round to two decimal places.)

Answers

Answer:
The length of the missing leg is 12 cm.

Explanation:

a² + b² = c² (Pythagoras theorem)

c is the hypotenuse (longest length) of a triangle.

a and b are the two other side of the triangle excluding the longest one.


Let x cm be the length of the missing leg of the right triangle.

x² + 5² = 13² (Pyth. Thm.)

x² = 13² - 5²

x² = 169 - 25

x² = 144

x = √144

x = 12

Hope it helps! Mark me brainliest if it’s correct.

The length of the missing leg given the hypotenuse is 13 cm and the other leg is 5 cm would be 12 cm.

What is the Pythagoras theorem?

The Pythagoras theorem states that the square of the longest side must be equal to the sum of the square of the other two sides in a right-angle triangle.

a² + b² = c² (Pythagoras theorem)

where, c is the hypotenuse (longest length) of a triangle.

And a and b are the two other side of the triangle excluding the longest one.

Let x be the length of the missing leg of the given right triangle.

x² + 5² = 13²

x² = 13² - 5²

x² = 169 - 25

x² = 144

x = √144

x = 12

Hence,  the length of the missing leg given the hypotenuse is 13 cm and the other leg is 5 cm would be 12 cm.

If a six-sided die is rolled 5 times, what is the probability of rolling numbers less than 3 ?

Answers

Distributions of probabilities help to model our world, allowing us to estimate the likelihood of a said event or to approximate the variability of incidence. It is a common way of describing the probability of an event as well as possibly forecasting it, and the further calculation can be defined as follows:

The possibility of rolling a six on a 6-sided die is [tex]\frac{1}{6}[/tex]. There are

Three 6's are therefore [tex]\binom{1}{6}^3[/tex] likely to roll.

The probability that you don't roll a 6 is [tex]\binom{5}{6}[/tex] and you are not 6 double the record is[tex]\binom{5}{6}^2[/tex].

In 5 tests, there are 10 different ways [tex]\binom{5}{3}=10[/tex] to rolle three 6s.

Then we all have together:

[tex]\to 10 \times \binom{1}{6}^3 \times \binom{5}{6}^2 \approx 0.0322[/tex]

Therefore, the final answer is "0.0322".
