Height

Mathematics
1 answer:
dem82 [27]3 years ago
8 0

Answer:

<h3>1 secs</h3>

Step-by-step explanation:

Given the height of the discus can be modeled by the equation y=−16x ^2 +32x+4, where y represents the  height in feet of the discus in seconds, the velocity of the discus at its maximum height is zero.

Velocity v = dy/dx = 0

dy/dx = -32x + 32

0 = -32x + 32

32x = 32

x = 1 secs

Hence it will take the discus 1 secs to reach its maximum height

Answer: The length of CU is 117 units.


Step-by-step explanation:

Given: ΔWCD≈ΔWUV

We know that if two triangles are similar, then their corresponding sides are proportional.

∴ \frac{WU}{WC}=\frac{WV}{WD}

\frac{36x-1}{26}=\frac{110}{20}\\\Rightarrow\ 36x-1=\frac{11}{2}\times26\\\Rightarrow36x-1=143\\\Rightarrow\ 36x=143+1\\\Rightarrow\ 36x=144\\\Rightarrow\ x=4

∴ WU=36(4)-1=143

Also , WU=WC+CU

⇒CU=WU-WC

⇒CU=143-26=117 units

Given the following triangle, if c = square root of 7 and a = 1, find the measure of B.
Darya [45]

Answer:

  68°

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you that the relation between the angle's adjacent side and the hypotenuse is ...

  Cos = Adjacent/Hypotenuse

This means ...

  cos(B) = a/c

  B = arccos(1/√7) ≈ 68°
