The fallout V from a volcanic explosion (measured in kilograms per square kilometer) depends on the distance d from the volcano

and the time t since the explosion began, so V equals f (d comma t ). Time is measured in hours and distance is measured in kilometers. What are the units of fraction numerator d f (10 comma t )over denominator d t end fraction?

Answer:

kgkm^{-2}hr^{-1}

Step-by-step explanation:

V=f(d, t) (measured in kilograms per square kilometer)

Time, t is measured in hours

Distance, d is measures in Kilometers

We want to determine the unit of \dfrac{df(10,t)}{dt}

Since V=f(d, t), \dfrac{df(10,t)}{dt}=\dfrac{dV}{dt}

Unit \:of\: V=f(d, t)=kg/km^2\\\text{Unit of t}=hr\\\text{Therefore the Unit of  } \dfrac{dV}{dt}=\dfrac{kg/km^2}{hr} \\=\dfrac{kg}{km^2hr} \\\\=kgkm^{-2}hr^{-1}

Please help me I'm so bad at math and doing AFDA really doesn't help.. Its quadratic equations matching solution sets.
stiv31 [10]

Answer:

(a)\ x + 4 = \±\sqrt9 ---- x =\{-7,- 1\}

(b)\ x - 4 = \±\sqrt9 ---- x = \{1,7\}

(c)\ x + 3 = \±\sqrt{16} ----- x = \{-7,1\}

(d)\ x - 3 = \±\sqrt{16} ---- x = \{-1,7\}

Step-by-step explanation:

Given

The attached equations

Required

Match each with the solution

(a)\ x + 4 = \±\sqrt9

Take the square root of 9

x + 4 = \±3

Solve for x

x =- 4  \±3

Split

x =\{- 4 -3,- 4 +3\}

x =\{-7,- 1\}

(b)\ x - 4 = \±\sqrt9

Take the square root of 9

x - 4 = \±3

Solve for x

x = 4 \±3

Split

x = \{4 -3,4+3\}

x = \{1,7\}

(c)\ x + 3 = \±\sqrt{16}

Take the square root of 16

x + 3 = \±4

Solve for x

x =- 3 \±4

Split

x = \{-3-4,-3+4\}

x = \{-7,1\}

(d)\ x - 3 = \±\sqrt{16}

Take the square root of 16

x - 3 = \±4

Solve for x

x =3 \±4

Split

x = \{3-4,3+4\}

x = \{-1,7\}

If g(x) = a f(x + b), how is f(x) transformed to get g(x)?
nevsk [136]

Answer:

There was a Horizontal translation left b units and then Vertical stretch or compression

Step-by-step explanation:

Given : g(x) = a f(x + b)

We are supposed to show the transformation

Rule : f(x)→f(x+c)

Horizontal translation left c units

So, f(x+b) is the Horizontal translation left b units

Rule : f(x)→cf(x)

Vertical stretch or compression

So,g(x) = a f(x + b)

So, Initially there was a Horizontal translation left b units and then Vertical stretch or compression
