Answer:
It would take approximately 6.50 second for the cannonball to strike the ground.
Step-by-step explanation:
Consider the provided function.

We need to find the time takes for the cannonball to strike the ground.
Substitute h(t) = 0 in above function.

Multiply both sides by 10.

For a quadratic equation of the form
the solutions are: 
Substitute a = -49, b = 305 and c=88

Ignore the negative value of t as time can't be a negative number.
Thus,

Hence, it would take approximately 6.50 second for the cannonball to strike the ground.
Answer: D) 10
============================================================
Explanation:
I'm assuming points M and N are midpoints of segments FD and FE respectively. If that's the case, then segment DE is twice as long compared to segment MN. We consider MN to be a midsegment.
So,
DE = 2*(MN)
3x-2 = 2*(x+4)
3x-2 = 2x+8
3x-2x = 8+2
x = 10
Round to the nearest thousands
8,276 = 8,000
2,451 = 2,000
8,000 + 2,000 = 10,000
answer
Maya traveled by plane about 10.000 miles
Answer:
Null hypothesis:
Alternative hypothesis:
The statistic to check the hypothesis is given by:
And is distributed with n-2 degrees of freedom
And the statistic to check the significance of a coeffcient in a regression is given by:

For this case is importantto remember that t1 and p value for test of slope coefficient is the same test statistic and p value for the correlation test so then the answer would be:
Always
Step-by-step explanation:
In order to test the hypothesis if the correlation coefficient it's significant we have the following hypothesis:
Null hypothesis:
Alternative hypothesis:
The statistic to check the hypothesis is given by:
And is distributed with n-2 degrees of freedom
And the statistic to check the significance of a coeffcient in a regression is given by:

For this case is importantto remember that t1 and p value for test of slope coefficient is the same test statistic and p value for the correlation test so then the answer would be:
Always
<h2><u>Complete Question: </u></h2>
Learning Task 1: Identify similar and dissimilar fractions. On your note- book write S if the fractions are similar and D if dissimilar.
1. 
2. 
3. 
4. 
5. 
<h2><em><u>The answers:</u></em></h2>
1.
- Similar (S)
2.
- Similar (S)
3.
- Dissimilar (D)
4.
- Dissimilar (D)
5.
- Dissimilar (D)
Note:
- Similar fractions have the same denominator. i.e. the bottom value of both fractions are the same.
- Dissimilar fractions have different value as denominator, i.e. the bottom value of both fractions are not the same.
Thus:
1.
- They have equal denominator. <u><em>Both fractions are similar (S).</em></u>
2.
- They have equal denominator. <em><u>Both fractions are similar (S).</u></em>
3.
- They have equal denominator. <em><u>Both fractions are dissimilar (D).</u></em>
4.
- They have equal denominator. <u><em>Both fractions are dissimilar (D).</em></u>
5.
- They have equal denominator. <em><u>Both fractions are dissimilar (D).</u></em>
Therefore, the fractions in <em><u>1 and 2 are similar (S)</u></em> while those in <em><u>3, 4, and 5 are dissimilar (D).</u></em>
