Answer:
The value for x is 40.
Step-by-step explanation:
So you know that the line that cuts through the right angle has one part of 10 degrees, and the other 2x degrees. A right angle is equal to 90 degrees, so the two parts, 2x and 10, have to equal 90. So the equation would look like this: 2x+10=90. Solve for x by subtracting 10 from both sides, resulting in 2x=80. Then divide both sides by 2, and get your answer of x=40.
The answer to this is d.) 1. This is because any number that is raised to the zero power is 1.
Step-by-step explanation:
y = x² - 16
x² = y + 16
x = sqrt(y + 16) because x is non-negative.
Hence the inverse function is f^(-1)(x) = sqrt(x + 16). (A)
' 36 = 9k ' is not an inequality. It's an <u>equality</u>, usually called an <em><u>equation</u></em>.
It's true whenever 'k' is 4, and false at any other time.
(You can determine that simply by dividing each side of the equation by 9.)
Sketch the points (0,5,2),(4,0,-1),(2,4,6) and(1,-1,2) o a single set of coordinate axes?
nordsb [41]
Explanation:
As points have three coordinates i.e. x, y and z hence the sketch of the given four points is drawn in 3D shape and for that picture is attached here with this answer.
Points are given in the format as below
(value of x-coordinate , value of y-coordinate , value of z-coordinate)
In the attachment:
Point A = (0,5,2) (in blue color)
Point B = (4,0,-1) (in purple color)
Point C = (2,4,6) (in orange color)
Point D = (1,-1,2) (in black color)
