How to solve this problem

. 0.3 [1.57 – (0.6)²]

Answers

well (1.57- 0.6 X 0.6) x 0.3 = 0.363

You would have to solve -(0.6)^2
Then you distribute
0.3 times 1.57 minus whatever -(0.6)^2 is.
Then subtract and you get your answer

Write the equation of the given line in standard form.

Answers

Answer:

x = 3

Step-by-step explanation:

"Standard form" is the form ...

... ax + by = c

where a, b, c are mutually prime integers. The coefficients a and b cannot both be zero. The leading coefficient must be positive. If "a" is zero, then the leading coefficient is "b".

So ...

... x = 3

is in standard form already. (a=1, b=0, c=3)

_____

Further comments on Standard Form

Of course, if the line has irrational slope or intercept, the coefficients cannot all be integers.

The order of the variables may be swapped, in which case the coefficient of y is the leading coefficient and must be positive.

This is the only way a vertical line can be written, as slope-intercept form is undefined for a vertical line.

The diameter of a face off circle on an ice hock rink is 30 feet what is the area

Answers

the area of a circe is π*r²
you are given that diameter=30 feet and the radius is half the diameter
so the area is
π*15² = 706.86 ft²

Select the correct difference. -3z 7 - (-5z 7) 2z7 8z14 -2z7 2z

Answers

Answer:

$2z^(7))$ .

Step-by-step explanation:

Given : $-3 z^(7) - ( -5 z^(7))$

To find : Select the correct difference.

Solution : we have given

$-3 z^(7) - ( -5 z^(7))$ .

Open the parenthesis

$-3 z^(7) + 5 z^(7))$ .

By the rule ( + - = -) .

$2z^(7))$ .

Therefore, $2z^(7))$ .

-3z^7 - (-5z^7) = -3z^7 + 5z^7 = 2z^7
