Answer: <1 = 26°
Step-by-step explanation:
given that:
• <ABD = 66°
• <2 = 14° + <1 (since ''more than' means we add)
• Find <1
Since it is obvious that <ABD is a sum of <1 and <2:
⇒ <ABD = <1 + <2
now we know that <2 is 14° more than <1 and that <ABD = 66°
⇒ 66° = <1 + (14° + <1)
⇒ 66° = <1 + 14° + <1
⇒ <1 = (66° - 14°) ÷ 2
⇒ <1 = 26° ...Answer...

The difference between two trinomials is 5x2 + 11x − 16. If one of the trinomials is 3x2 − 2x + 7, then which expression could be the other trinomial?
Applying the difference, it is found that the other trinomial could be given by: 8x² + 9x - 9.
What are the trinomials?We are working with second degree trinomials, hence:
One is 3x² - 2x + 7.The other is ax² + bx + c.The difference is 5x² + 11x - 16.Hence:
ax² + bx + c - (3x² - 2x + 7) = 5x² + 11x - 16.
(a - 3)x² + (b + 2)x + c - 7 = 5x² + 11x - 16.
Then:
a - 3 = 5 -> a = 8.b + 2 = 11 -> b = 9.c - 7 = -16 -> c = -9Then, the trinomial is:
8x² + 9x - 9.

sin-¹ (sin 17°) = [ ? ]°
The value of sin⁻¹ (sin 17°) is 17° or 17 degree after applying the trigonometric identity sin⁻¹ (sinx) = x
What is trigonometry?Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.
We have:
= sin⁻¹ (sin 17°)
The above expression represents an angle.
Let's suppose the angle is x and sin of x is sinx
sinx is a ratio of side opposite to the angle to hypotenuse.
If we take sin inverse of sinx we get an angle of x.
sin⁻¹ (sinx) = x
sin⁻¹ (sin 17°) = 17 degree
Thus, the value of sin⁻¹ (sin 17°) is 17° or 17 degree after applying the trigonometric identity sin⁻¹ (sinx) = x

Let (-3, 5) be a point on the terminal side of 0.
Find the exact values of cos0, csc 0, and tan 0.
Answer:

Step-by-step explanation:
Accorded to trigonometric formula, we know that:
[tex]\displaystyle \large{\cos \theta = \dfrac{x}{r}}\\\\\displaystyle \large{\csc \theta = \dfrac{1}{\sin \theta} = \dfrac{1}{\frac{y}{r}} = \dfrac{r}{y}}\\\\\displaystyle \large{\tan \theta = \dfrac{\sin \theta}{\cos \theta} = \dfrac{y}{x}}[/tex]
We know what x and y are but not yet knowing what r is. We can find r (radius) using the formula:
[tex]\displaystyle \large{r=\sqrt{x^2+y^2}}[/tex]

[tex]\displaystyle \large{r=\sqrt{(-3)^2+(5)^2}}\\\\\displaystyle \large{r=\sqrt{9+25}}\\\\\displaystyle \large{r=\sqrt{34}}[/tex]
Hence, radius is √34 and we know all we need now. Substitute x = -3, y = 5 and r = √34 in respective areas.
[tex]\displaystyle \large{\cos \theta = \dfrac{-3}{\sqrt{34}} = -\dfrac{3\sqrt{34}}{34}}\\\\\displaystyle \large{\csc \theta = \dfrac{\sqrt{34}}{5}}\\\\\displaystyle \large{\tan \theta = -\dfrac{5}{3}}[/tex]

What are Chords?Chords are line segment joining any two sides of a circumference of a circle.
The radius of a circle is half of diameter of the circle.
Therefore, a radius or diameter that is perpendicular to a chord divides the chord into two equal parts and vice versa.
Hence, the radius that runs through M is perpendicular to the chord AC. Therefore, the chord AC is divided into two halves namely AM and MC.

AC = AM + MC

Answer:
x ≤ 1/2
Step-by-step explanation:
Domain: input values (x-values)
We cannot take a square root of a negative number, therefore
3 - 6x ≥ 0
Solving the inequality:
⇒ 3 - 6x ≥ 0
⇒ 3 ≥ 6x
⇒ 1/2 ≥ x
⇒ x ≤ 1/2
Therefore, the domain is x ≤ 1/2
What is an equation of the line that passes through the point (-7,-6) and is parallel to the line x-y=7?
Answer:
y = x + 1
Step-by-step explanation:
Step 1: Find the slope.
Parallel lines have the same slope. That means that the line we are seeking is going to have the same slope as line x - y = 7.
To find the slope of the line x - y = 7 let's change it to the slope-intercept form.
Slope-Intercept Form
y = mx + b
m ... slope
b ... y-intercept
Let's change the equation of the parallel line to slope-intercept form (isolate y).
x - y = 7
Add y on both sides.
x - y + y = 7 + y
x = 7 + y
Subtract 7 on both sides.
x - 7 = 7 + y - 7
x - 7 = y
y = x - 7
Let's read the slope from the equation.
Instead of y = x - 7 we can write y = 1x -7.
Now it's obvious that m (slope) is 1.
m = 1
So far, our equation of the line is:
y = 1x + b
which is te same as
y = x + b
Step 2: Find y-intercept.
To find out y-intercept (b), we substitiute the point (-7, -6) in the equation. Points are in form (x, y) so -7 is x and -6 is y.
y = x + b
-6 = -7 + b
Solve for b.
1 = b
Step 3: Substitute slope and y-intercept in general formula for slope-intercept form of the line.
Now substitute m and b in slope-intercept form y = mx + b.
m = 1
b = 1
Equation of the line:
y = x + 1

function : no, because x = -1 has 2 different y values assigned (7 and 2). that violates the definition of a function.

Using the simple interest formula,
I = PRT
From the given information,
P = $2,000,000

Step-by-step explanation:
x²-5x-9x+45
x(x-5)-9(x-5)
(x-9)(x-5)
Answer:
(x-9)(x-5)
Step-by-step explanation:
To factor this expression, you need to find two values that have a sum of -14 and also have a product of 45. The values -5 and -9 meet these requirements and become the constants in the two factors of the expression,
x2 − 14x + 45 = (x − 9)(x − 5).
