Need help....ASAP on both 7 AND 8
1 answer:
Answer:
7)Amount of calories Ethan would burn running for 5 hours in one week= calories
8)Erosion caused by wave for 8 years would be= cm
Step-by-step explanation:
7) Ethan burns 650 calories on running for an hour.
Amount of calories he would burn running for 5 hours in one week= calories
8) Erosion caused by wave per year =3 cm
Erosion caused by wave for 8 years would be= cm

Assuming that by "16t2" you mean :
First of all, let's compute the position at the two required times:
So, the ball traveled a total distance of , during the time
.
The average rate of change is the ratio between these two:
Based on the above, the Triangle XYZ and ACB are known to be similar triangles since tanX = tanA = 5 over 2 and 5 tenths;
Hence:
- AC = 2 x XY
- CB = 2 x YZ
From the question given; Triangle XYZ is known to have been dilated by a scale factor of 2 to form a type of triangle known as triangle ACB, So therefore, XYZ and ACB are known to be the same or similar triangles.
Since Angles Y and C are known to both measure 90 degrees, and angles A and X are said to be congruent. Therefore:
tanX = tanA = 5 over 2 and 5 tenths
AC = 2 x XY
CB = 2 x YZ
For part B:
cosX=Base/Hypotenuse
cos A=AC/AB
AC = 2.05
AB = 5.59
Therefore, Based on the above, the Triangle XYZ and ACB are known to be similar triangles since tanX = tanA = 5 over 2 and 5 tenths;
Hence:
- AC = 2 x XY
- CB = 2 x YZ
