Janelle fired a projectile and measured its range. Shehypothesizes that if the magnitude of the initial velocity is doubled and

theangle of the velocity remains the same, the projectile will travel twice as far as itdid before. Do you agree with her hypothesis? Explain.

Answer:

  No

Step-by-step explanation:

If the projectile lands at the same height it was launched from, then its time of flight will be proportional to the vertical speed. Its horizontal distance will be the product of its horizontal speed and its time of flight, so will be proportional to the square of the velocity.

If the velocity is doubled, the projectile can be expected to travel 2² = 4 times as far, not twice as far.

You have two exponential functions. One function has the formula g(x) = 3(2 x ). The other function has the formula h(x) = 2 x+1
Alika [10]
The answer:

the main formula which should be used to reply this is:

g(x) - h(x) = (g-h) (x)

if the question does mean <span> g(x) = 3(2 ^ x )
</span>
k(x)= (g – h)(x) = 3(2 ^x ) - 2 ^(x+1)

 and we know that because of   a^x+p = a^*a^p

=3(2 ^x ) - 2 ^(x)2^1=(2 ^x )(3 - 2^1)

=(2 ^x )(3 - 2^1)= 2 ^x 

the answer is <span>k(x) = 2^x</span>

What is the estimated ansewr for 318×3
Finger [1]
I would estimate this around 960 since 318 is close to 320 and 320x3 is 960, the actual answer would be 3x318 which is 954.

Roll a die 10 sided die 3 times. What is the probability that the sequence is strictly increasing or decreasing?
snow_lady [41]

Answer:

The probability of obtaining a sequence which is neither strictly increasing nor decreasing in 0.76.

Step-by-step explanation:

We have 10 possible outcomes on a single throw.

So, outcomes in 3 throws = 10^{3} =1000 outcomes.

Let x be the number of strictly increasing arrangements.

Let y be the number of strictly decreasing arrangements.

Let z be the number of outcomes that are neither strictly decreasing nor strictly increasing

So, we have x+y+z=1000

If we look at a strictly increasing arrangement from the other/opposite side, it will look like a strictly decreasing arrangement.

So, x = y

Hence, we can say the final equation will be :

2x+z=1000

And for strictly increasing arrangements ,all 3 numbers will be different and it can be done in 10C3 ways.

10C3=\frac{10!}{3!7!} = 120 ways

So, 2x=2\times120=240

Thus z=1000-240=760

So, the probability is = \frac{760}{1000} = 0.76

Therefore, the probability of obtaining a sequence which is neither strictly increasing nor decreasing in 0.76.
