Without solving, explain how you can tell whether the solution to 0.5x = 10 is less than 1 or greater than 1

Greater than 1 because left side is a fraction less than 1 and right side is a number greater than 1.

The left side being a fraction less than 1 could only mean that you have to multiply a number greater than 1 to the other side. And since the other side is a number greater already than 1 then multiplying the left side to the right side must result in a number greater than 1.

Use the Sine Law: $\frac{sin(A)}{a} = \frac{sin(B)}{b} = \frac{sin(C)}{c}$

In this case:
$\frac{sin(44)}{17}=\frac{sin(60)}{e}$
therefore:
$e=17\frac{sin(60)}{sin(44)} \approx 21.2$

A blimp can be seen flying at an altitude of 5500 feet above a motor speedway during a race. The slanted distance directly to th

Vladimir [108]

Answer:

The expression of h as function of x is h = $\sqrt{(d + 5500) (d - 5500)}$

Step-by-step explanation:

Given as :

The distance of blimp (AB) = 5500 feet

The slanted distance to the pagoda (BC) = d feet

The horizontal distance (AC) = h

Let the angle made between slanted distance and horizontal distance be Ф

So , cos Ф = $\frac{AC}{BC}$ = $\frac{h}{d}$

And sin Ф = $\frac{AB}{BC}$ = $\frac{5500}{d}$

∵, cos²Ф = 1 - sin²Ф

So, $(\frac{h}{d})^{2}$ = $1 - (\frac{5500}{d})^{2}$

Or, $(\frac{h}{d})^{2}$ = $(\frac{d^{2}- 5500^{2}}{d^{2}})$

Or, h² = d² - 5500²

∴ h = $\sqrt{d^{2}- 5500^{2}}$

Or, h = $\sqrt{(d + 5500) (d - 5500)}$

Hence The expression of h as function of x is h = $\sqrt{(d + 5500) (d - 5500)}$ Answer

A box of pencils costs $10.The total cost (c) as a function of the number of boxes (b) is expressed as c = f(b) = 10b. What is t

Wittaler [7]

Answer:

Domain (b) = {0, 1, 2, 3, 4....}

Set of all whole numbers

Step-by-step explanation:

Given: A box of pencils costs $10.

Total cost (c) = 10b, where "b" is the number of boxes.

Here c represents the range which is dependent variable and b represents the number of boxes which is independent variable.

For instance, if you buy 10 boxes of pencils, you need to pay = 10(10) = $100

Here we replace b with the number of boxes.

The number of boxes cannot be negative. It will star from 0,1, 2, 3....

Therefore, domain (b) = {0, 1, 2, 3, 4....} which is set of whole numbers.
