Answer:
The value of b is either + 6 or -6
Step-by-step explanation:
Here, given that we have the value for the discriminant, we want to calculate the value for the coefficient of x
mathematically, the discriminant can be calculated using the equation;
D = b^2 - 4ac
a represents the coefficient of x^2 which is 3
b represents the coefficient of x given as b
2 represents the last number
D is the discriminant = 12
So we have that;
12 = b^2 - 4(3)(2)
12 = b^2 - 24
b^2 = 24 + 12
b^2 = 36
b = √36
b = +6 or -6
A circular plate has circumference 32 inches. What is the area of this plate? Use 3.14 for pi. The area of this plate is about nothing square inches.
Answer: The area of the plate is 81.67 in^2
Step-by-step explanation:
If we have a circle of radius R, the area of this circle can be computed as:
A = pi*R^2
where pi = 3.14
And the circumference is:
C = 2*pi*R
and we know that this is equal to 32 in, then:
32in = 2*pi*R
Now we can isolate R, and we get:
32in/(2*pi) = R
32in/(2*3.14) = R = 5.1 in
Then the area of the plate is:
A = 3.14*(5.1in)^2 = 81.67 in^2

Answer:
y = -1/2x + 1
Step-by-step explanation:
(0,1) and (2,0)
Slope:
m=(y2-y1)/(x2-x1)
m=(0-1)/(2-0)
m=(-1)/2
m= -1/2
Slope-intercept:
y - y1 = m(x - x1)
y - 1 = -1/2(x - 0)
y - 1 = -1/2x
y = -1/2x + 1

Choose the Algebraic equation that matches the table
A) y = x - 3
B) y = x + 2
C) y = x - 2
D) y = -x - 2
Answer:
C) y = x-2
Step-by-step explanation:
0-2= -2
2-2= 0
3-2= 1
4-2= 2
And all of that checks out because the values I just got for y are the same as the table

Explain how to use the unit-factor method to convert 120 pounds to kilograms.
Hint: 1 kilogram=2.2 pounds
To write the unit factors, use the / symbol, like this: 1 gallon/3.79 liters.
The converted units is 120 pounds = 54.5 kilogram
How to convert the units?As a general rule, we have:
1 kilogram=2.2 pounds
Multiply both sides by 120
120 * 1 kilogram=2.2 pounds * 120
Divide both sides by 2.2
120/2.2 * 1 kilogram=2.2 pounds * 120/2.2
Evaluate the products
54.5 kilogram= 120 pounds
Rewrite as:
120 pounds = 54.5 kilogram
Hence, the converted units is 120 pounds = 54.5 kilogram

The price of a holiday was decreased by 12 percent to 600 . What was the price before the decrease?
Price before decrease = x
If price before decrease is 100, then price after decrease = 100- 12 = 88
100:88 = x:600
100/88=x/600
100/88 ×600 = x
681.82 =x
Price before decrease =681.82

Step-by-step explanation:
Angle P is intercepted by two arcs.
SB and RQ.
We can use this theorem,
If two chords intersect inside a circle, then the measure of the angle formed is one half the sum of the measure of the arcs intercepted by the angle and its vertical angle.
So in other words,
[tex] \frac{80 + 150}{2} = rpq[/tex]
[tex]rpq = 115[/tex]
What is the slope of OA?
Answer:
D) b/a
From the given figure, O = (0, 0) and A = (a, b)
Slope of OA = (y2 - y1) / (x2 - x1)
Here x1 = 0, y1 = 0, x2 = a and y2 = b.
Slope of OA = (b - 0)/(a - 0)
Slope of OA = b/a
Answer: D) b/a

24 59' 60'' is equivalent to what degrees
Answer:
25 degrees
Step-by-step explanation:
The computation is shown below:
24°59'60" = 24°+59'+60"
Now
As we know that
1'=60"
i.e. (1 minute = 60 seconds)
so,
24°+59'+60" = 24°+59'+1'
=24°+60'
Also,
1°=60'(1 degree=60 seconds)
= 24°+1°
=25°
