The expressions [tex]1.8^2 + 3 $ and $ 7 - 2 \times 0.43[/tex] should be joined by not equals sign to form an inequality.
Given the expressions, 1.8² + 3 and 7 − 2⋅0.43,
Evaluate each of the expressions to find out if they are equal or not.
Thus:
1.8² + 3 = 3.24 + 3
1.8² + 3 = 6.24
7 − 2⋅0.43 = 7 - 0.86
7 − 2⋅0.43 = 6.14
Both expressions are not equal.
Therefore, the complete statement would be:

3x - y^2 = 12
3x - (-3)^2 = 12
3x - 9 = 12
3x = 12 + 9

Step-by-step explanation:
To get the derivative of [tex]ax^{n}[/tex], simply use the following formula:
[tex]a(n)x^{n-1}[/tex]
We have the function, h(x) = -5x^2 + 20x
Using the formula, we get the derivative to be:
-10x + 20

If you earn both hourly wages and a commission at your job, your gross wages, w, can be calculated with the following equation:
cs + rh = w
where c is your commission rate, s is your total sales in dollars, r is your hourly rate, and h is your hours worked.
Solve for s to rewrite the equation for total sales.
Question 1 options:
s = w + rhc
s = c(w + rh)
s = c(w − rh)
s = w − rhc
Answers
Applying the equation, it is found that the solution for s is given by:
[tex]s = \frac{w - rh}{c}[/tex]
The equation we are going to work in this problem is given by:
[tex]cs + rh = w[/tex]
We want to solve for s, hence, we have to isolate s, first placing rh on the other side with the inverse signal(subtraction).
[tex]cs = w - rh[/tex]
Division is the inverse of multiplication, thus, c is multiplying s, it goes to the other side dividing:
[tex]s = \frac{w - rh}{c}[/tex]
Which is the solution for s.

Trigonometric functions

Answer:
β ≈ 39.9°
θ ≈ 50.1°
Step-by-step explanation:
The mnemonic SOH CAH TOA is intended to remind you of the relationships between the sides of a right triangle and the trig functions of the acute angles.
For angle β, we know the opposite side and the hypotenuse, so the relevant relation is ...
Sin = Opposite/Hypotenuse
sin(β) = 61/95
The inverse function is used to find the angle when the sine is known.
β = arcsin(61/95) ≈ 39.9°
Of course, the angle θ is the complement of this:
θ = 90° -39.9° = 50.1°
Answer:
Step-by-step explanation:
sin β = 61/95 = 0.642105
β = 39.95 degrees.
O = 90 - 39.95
= 50.05 degrees
cos O = 61/95.
Note that cos (90-β) = sin β.

Answer:

Step-by-step explanation:
according to the sum of the exterior angles of a polygon, we get that the exterior angles of this polygon add up to 360
so our equation is: 9x-31+7x-2+4x+33=360,
the -31-2+33 cancel out,
and combining like terms gives us: 20x=360
so x=18,
from here we know that DCE equals to 180-7x+2, because it is an exterior angle, therefore the angle is 180-126+2, which is 56
