Answer:
2 and 3.
Step-by-step explanation:
Four to the second power is 16.
Four to the third power is 64.
30 lies between 16 and 64, thus the exponent must lie between 2 and 3.
Answer: no solution
Step-by-step explanation:
We can see that both triangles are right angle triangle as per information given into picture. So we will prove that they are similar then use properties of similar triangle to find the value of d.
In triangle STV and triangle XWV:
∠STV = ∠XWV { both are equal to 90 degree}
∠TVS = ∠WVX { vertically opposite angles are equal}
Hence by AA (Angle Angle) similarity postulate of the triangles, It is proved that triangle STV and triangle XWV are similar.
We know that ratio of corresponding sides of similar triangles are equal so we can write:


350*180=400d
63000=400d
divide both side by 400
157.5=d
Hence final answer is d=157.5 m.
Answer:
40 mph
Step-by-step explanation:
average speed 40mph
It would be y=1/2x-3. You can plug in some numbers to see it. Like, plug in 8. Half of 8 is 4, and 4-3=1. Plug in 12. Half of 12 is 6, and 6-3=3. I hope that helps! :)
