Answer:
1.27
Step-by-step explanation:
When completing word problems, it's always important to first turn everything into an equation.
The volume of a rectangular box is:
Where <em>l</em> is the length, <em>h</em> is the height, and <em>w</em> is the width.
Which we can write down the equation:
Next up, distribute:
We have a cubic equation, you can solve it using a calculator.
We have three solutions, and they are:
Since lengths cannot be negative, there is just one solution:
And rounding it gives:
And don't forget to put ft at the end!
Answer:
The equation in standard form is:
Step-by-step explanation:
Since they give you the x-intercepts (the zeros of the quadratic expression) one knows that the binomials: (x-(-3)) and (x-4) must be factors of the quadratic expression.
We can therefore write the equation as:
using the binomial factors given above, and a numerical factor "k" that we can determine by using the information that the graph passes through the point (2,-20):
Then,the equation can be written as:
where we wrote the equation already in standard form
Step-by-step explanation:
Let the larger no be = a
Difference of the numbers = a - 32
As per the question;
(a + 32) = 5(a - 32)
⇒ a + 32 = 5a - 160
⇒ 128 = 4a
⇒ a = 32
∴ The larger no is 32.

Step-by-step explanation:
Given the function f(x) for which
If you want to plot the corresponding points for the inverse of the function f(x), change into :
switch x and y
and then change into
You get
Now plot these points on the coordinate plane (see attached diagram).
