Why is radian measure used in Geometry?

The infinite series description of trig functions is much neater when the argument is radians. For example, for small angles, sin(x) ≈ x when x is in radians. You could say that radians is the "natural" measurement unit for angles, just as "e" is the "natural" base of logarithms.

If the angle measure were degrees or grads or arcseconds, obnoxious scale factors would show up everywhere.

Write each polynomial in standard form. Then give the leading coefficient. You may need to combine like terms before writing the

Bond [772]

Step-by-step explanation:

To write a polynomial in standard form, put the degree that are the greatest first

So here it would be

${x}^{5} + 4 {x}^{3} - 3 {x}^{2} + 10$

Remember constant are numbers that you learned back in elementary,

Numbers like 10,90,4,1,0,-3 etc.

Remember that constant are basically represented like this

$k \times {x}^{0}$

For example, 10 is represented like

$10 \times {x}^{0}$

Since 0 is the smallest degree possible, for a polynomial, constants are the last term of a polynomial in standard form

A zoo in oklahoma charged $22 for adults and $15 for children. During a summer day, 732 zoo tickets were sold, and the total rec

Vlad [161]

Answer: Cost of tickets for adults = $22

Cost of tickets for children = $15

Total number of tickets sold = 732

Total receipts = $12,912

Let x be number of adult ticket's sold and y be the number of child ticket's sold.

Therefore, we have:

$x+y=732$ --------------- equation 1

$x=732-y$

Also, we have:

$22 x+15y=12,912$

Now, let's substitute the value of x:

$22 (732-y)+15y=12912$

$16104-22y+15y=12912$

$16104-7y=12912$

$7y=16104-12912$

$7y=3192$

$y=\frac{3192}{7} =456$

Now, let's substitute the value of y=456 in equation 1, we have:

$x+456=732$

$x=732-456$

$x=276$

Therefore, the number of child ticket's sold is 456 and number of adult ticket's sold is 276
