Answer:

V(m) = (2 + 5m)^3

Step-by-step explanation:

Given

Solid Shape = Cube

Edge = 2 feet

Increment = 5 feet per minute

Required

Determine volume as a function of minute

From the question, we have that the edge of the cube increases in a minute by 5 feet

<em>This implies that,the edge will increase by 5m feet in m minutes;</em>

Hence,

New\ Edge = 2 + 5m

Volume of a cube is calculated as thus;

Volume = Edge^3

Substitute 2 + 5m for Edge

Volume = (2 + 5m)^3

Represent Volume as a function of m

V(m) = (2 + 5m)^3

x²(x - 4)(2x + 5) = 0

x² = 0       or    x - 4 = 0     or        2x + 5 = 0

√x = √0   or          x = 4     or               2x = -5

  x = 0                                                     x = -\frac{5}{2}

Answer: 0, 4, -\frac{5}{2}

BartSMP [9]

Answer:

30 mL

Step-by-step explanation:

Mr. Allen needs 100 mL of a solution that is

  • 30% vinegar,
  • 15% lemon juice,
  • 55% water.

Thus, there are

100\cdot 0.3=30\ mL of vinegar,

100\cdot 0.15=15\ mL of lemon juice,

100\cdot 0.55=55\ mL of water.

15) factor out cos: cos(x)(sin(x)+1)=0
Now this is true when either cos(x)=0 (x=pi/2 and 3pi/2)
Or when sin(x)=-1 (x=3pi/2)
So it's solutions are pi/2 and 3pi/2

The price of a video game was reduced from $60 to $45. By what percentage was the price of the video game reduced?* O 15% O 25%
Naya [18.7K]

Answer:

25

Step-by-step explanation:

The new price, $45, can be expressed as a percentage of $60 by taking it as a fraction of $60, converting to a decimal value, and multiplying by 100%. $45/$60=3/4=0.75, 0.75x100%=75%. So since 100%-75%=25%, the value was reduced by 25%.

Which is equivalent to sin^-1(tan(pi/4)) ? Give your answer in radians.
aleksklad [387]
We are to find the value of sin^{-1}(tan( \frac{ \pi }{4}))

First we evaluate tan(π/4). The value of tan(π/4) is 1. 

So, 

sin^{-1}(tan( \frac{ \pi }{4})) =sin^{-1} (1)

sin(π/2) = 1
So,
sin^{-1}(1)= \frac{ \pi }{2}

Thus, we can write:

sin^{-1}(tan( \frac{ \pi }{4}))= \frac{ \pi }{2} radians.

So, the answer to this question is π/2 radians.
