The dive of the Peregrine falcon took 7.5 seconds

How to solve such time related questions?

The key concept for solving such questions is the relationship between speed, distance and time.

The relationship between them is Distance = Speed X Time

Assuming the top speed of  a Peregrine falcon is 240mph.

Distance travelled by the Peregrine falcon = 0.5 miles

By using the formula we get

0.5 = 240 x time

time = [tex]\frac{1}{480}[/tex] hours

time = [tex]\frac{3600}{480}[/tex] seconds = 7.5 seconds

Step-by-step explanation:

Dividing by a fraction is the same as multiplying by its reciprocal.

6 ÷ 1/3

= 6 x 3/1

= 6 x 3

= 18

The number of sections of the board Shara has when she is finished cutting is 18 sections.

A fraction is written in the form of a numerator and a denominator where the denominator is greater that the numerator.

Example: 1/2, 1/3 is a fraction.

We have,

Length of the board = 6 feet

Length of the section = 1/3 feet

The number of 1/3 feet sections.

The solution of the given exponential equation is 0.688.

Given that Mike is working on solving the exponential equation 37ˣ = 12.

An exponential equation is an exponential equation where the power (or)  part of the exponent is a variable.

firstly, we have to slve this equation is by converting it to logarithmic form. Any exponential equation can be transformed into an equivalent logarithmic equation as follows:

aˣ = y

logₐy = x

Now, we will apply this transformation to our equation and we get

log₃₇12=x

Further, we will apply the change of base formula so that solution is written in terms of base 10 logs:

x=log12/log37

So, this is an exact answer to given equation, but we can simplify it further by using decimal approximation of it using a calculator. Remember that these logs are base 10:

x≈1.079/1.568

x=0.688

Hence, the solution of the given exponential equation 37ˣ=12 is 0.688.

Answer:

f(-x) = -4x^3 + 9x, f(x) is an odd function

Step-by-step explanation:

We are given that f(x) = 4x^3 - 9x. In order to solve this problem, we first need to understand what an odd function is and what an even function is. When we have an odd function, f(-x) = -f(x). Meaning, that if we plug -x in for x, we should get -f(x). On the other hand, with an even function, f(-x) = f(x). Even if you change the sign, when you simplify, you will get back the same function. In either case, we have to first find f(-x) to figure this problem out:

[tex]f(-x)=4(-x)^3-9(-x)\\f(-x)=-4x^3+9x[/tex]

We can see from our answer for f(-x) that it is equal to -f(x). We can verify this below:

[tex]-f(x)=-(4x^3-9x)\\-f(x)=-4x^3+9x[/tex]

Since f(-x) = -f(x), our function f(x) is an odd function
