Answer:

z*(z - 3) = 520

Use the following representations:

Width:  W  

Length:  L = W + 3, or W = L - 3

Area = L*W = L*(L - 3) = 520

Equation b) is the correct one:  z*(z - 3) = 520

Answer:

Step-by-step explanation:

Given that:

Ava bring 34 food to the picnic

Kate bring 16 food to the picnic

JIn brings 112 food to the picnic

To enter these digits by applying equivalent fractions with a denominator of 12;

Their respective numerical expression is:

Ava = \dfrac{34}{12}

Ava brought 2 \dfrac{5}{6} food to the picnic

Kate = \dfrac{16}{12}

Kate brought 1 \dfrac{1}{3} food to the picnic

Jin = \dfrac{112}{12}

Jin brought 9 \dfrac{1}{3} food to the picnic

Justin launches a rocket straight up into the air. The table below gives the height(t) of the rocket (in meters) at a few times
Papessa [141]

Using it's formula, the average rates of change are given as follows:

a) 30 meters per second.

b) -10 meters per second.

<h3>What is the average rate of change of a function?</h3>

The average rate of change of a function is given by the <u>change in the output divided by the change in the input.</u> Hence, over an interval [a,b], the rate is given by the following equation:

r = \frac{f(b) - f(a)}{b - a}

For item a, taking the data from the table, we have that:

  • f(0) = 0.
  • f(4.6) = 138.

Hence the rate is given as follows:

r = (138 - 0)/(4.6 - 0) = 30 meters per second.

For item b, taking the data from the table, we have that:

  • f(9.2) = 23.
  • f(11.5) = 0.

Hence the rate is given as follows:

r = (0 - 23)/(11.5 - 9.2) = -10 meters per second.

The parent function f(x) = x3 is transformed to g(x) = (x – 1)3 + 4. Identify the graph of g(x).
Dominik [7]

we have f(x)=x^3 which is a cubic function.

and =(x-1)^3+4.

from f(x) and g(x) we know that both are cubic and g(x) has shrink of 1 and up by 4 units in x axis .

A certain number exceeds 18 by as much as 44 exceed the number. What is the number?
asambeis [7]

Answer:

x=31  is the required number.

Let the number be represented as "x".

Then, According to the statement given, "x" exceeds by as much as 44 exceed the number, then the equation can be written as:

⇒x-18=44-x

⇒x+x=44+18

⇒2x=62

⇒x=31

Hence, the required number is x =31.
