Given the quadratic function 8x2 - 5x + 3 = y, which statement is true?
a. The quadratic is expressed in standard form; a= -8, b=5, and c= -3.
b. The quadratic is expressed in standard form; a=8, b= -5, and c=3.
c. The quadratic is expressed in standard form; a = 8, b=5, and c= -3.
d. The quadratic is not expressed in standard form because the equation is not equal to 0.
Answer:
b. The quadratic is expressed in standard form; a=8, b= -5, and c=3.

Answer:
6/5
Step-by-step explanation:
If you are looking for the slope of the line it is 6/5 because starting from the origin you rise 6 (go up in this case) and run (go right in this case) 5 from the two points that you were given. The line is also going in an upwards direction so the slope is also positive. If you want to write the slope-intercept form equation you would use the slope intercept formula y=mx+b and plug in your slope (6/5) and your y-intercept, which is just 0 because it is at the origin and you would get y=6/5x or y=6/5x+0.

Point B is a point of tangency. Find the radius r of OC.
Answer:
r = 16 units
Step-by-step explanation:
From the figure attached,
AB is the tangent drawn from a point A to the circle C.
BC = r [Radius of the circle]
Length of AC = (18 + r)
AB = 30
By the property of a tangent drawn to a circle,
"Radius of a circle and tangent are perpendicular to each other"
AB ⊥ BC
By applying Pythagoras theorem in ΔABC,
AB² + BC² = AC²
(30)² + r² = (r + 18)²
900 + r² = r² + 36r + 324
36r = 900 - 324
r = [tex]\frac{576}{36}[/tex]
r = 16 units
WXYZ is a rhombus. What is m of angle XYZ?
Answer:
112
Step-by-step explanation:

8x=80
x=10
180-90-(3x+4)=90-34=56
56×2=112
"What is the GCF (greatest common factor) of 60x^3- 10x^2+ 30x?
Answer:
10x
Step-by-step explanation:
Given the expression 60x^3- 10x^2+ 30x, we are to find the GCF
First let us find the factors of each terms
60x³ = 6 * (10 * x) * x²
10x² = 1 * (10 * x) * x
30x = 3 * (10 * x)
From the three factors, you can see that 10*x is common to them all. Hence the GCF of the expression will be 10x

Answer:
x ≈ .1138985869
Step-by-step explanation:
[tex]tangent = \frac{opposite}{adjacent}[/tex]
[tex]tan(\frac{10}{x} ) = 26[/tex]
[tex]tan^{-1}[ tan(\frac{10}{x} )] = tan^{-1}(26)[/tex]
[tex]\frac{10}{x} = tan^{-1}(26)[/tex]
[tex]10 =x[ tan^{-1}(26)][/tex]
[tex]\frac{10}{tan^{-1}(26)} =x[/tex]
x ≈ .1138985869

Answer:
The answer is 980.
Step-by-step explanation: to follow pemdas you first start with the exponents for there are no parenthesis. So to do this 14^2 is just 14x14 with is 196. Then you take that and multiply it by the 5 to get your end product. 196x5=980.
Hope this helps.
