Answer:  f(t)=35400(1.02)^t

Step-by-step explanation:

The exponential growth function is given by :-

f(t)=A(1+r)^t...(i)

, where A = initial value , r= rate of growth ( in decimal) and t is time (usually in years).

Given,The population of a city is 35,400. The population is expected to grow at a rate of 2% each year.

i.e. A=  35,400

r=2%=0.02  [we divide percent by 100 to convert it into decimal]

Substitute all values in (i), we get the function represents the population of the city after t years :

f(t)=35400(1+0.02)^t\\\\f(t)=35400(1.02)^t

Which graph represents the function f(x)=-|x|-2?
skad [1K]

Answer:

ind the absolute value vertex. In this case, the vertex for y=−|x|−2 is (0,−2).

(0,−2)

The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined.

Interval Notation:

(−∞,∞)

Set-Builder Notation:  {x|x ∈ R}

For each x value, there is one y value. Select few x values from the domain. It would be more useful to select the values so that they are around the x value of the absolute value vertex.

−2   −4

−1    −3

 0   −2

 1    −3

Given that 35.8 x 4.23= 151.434<br>write down a division sum with an answer of 423.​
Nina [5.8K]

Answer:

  151434/358 = 423

Step-by-step explanation:

Every product with non-zero factors can be written as an equivalent division relation.

  a·b = c   ⇒   a = c/b

Here, we have 35.8 × 4.23 = 151.434. This can be written as the equivalent ...

  4.23 = 151.434/35.8

We can multiply this by 100 to get a division relation with a quotient of 423:

  423 = 15143.4/35.8

If we want, we can move the decimal points another place to the right to get ...

  151434/358 = 423
