If Line Overline BC Is The Diameter Of The Circle Below,What is The area of the circle
Answers
The area of the circle of diameter BC is the amount of space on the circle
Using the assumed value, the area of the circle is 19.625
How to determine the areaThe circle is not given.
So, I will assume a value for length BC
Assume the length of BC is:
BC = 5
The area of the circle would be:
[tex]Area = \pi (\frac{BC}{2})^2[/tex]
So, we have:
[tex]Area = 3.14 * (\frac{5}{2})^2[/tex]
Evaluate the product
[tex]Area = 19.625[/tex]
Using the assumed value, the area of the circle is 19.625

The lengths of the red drum species of fish have an approximately Normal distribution, with a mean length of 24 inches and a standard deviation of 1.4 inches. What proportion of red drum fish are between 22 and 23.5 inches in length?
Answers
Answer:
0.2830
Step-by-step explanation:
edge
The required proportion of red drum fish would be 0.2830 between 22 and 23.5 inches in length.
What is Z -score?A Z-score is defined as the fractional representation of data point to the mean using standard deviations.
As per the given condition, if the fish is between 22 and 23.5 inches,
P(22≤ X ≤ 23.5)
You can rewrite it as:
⇒ P(X ≤ 22) - P(X ≤ 23.5)
The first step is to standard both values before using population data and the standard normal distribution to get the probability:
The formula of the standard normal is Z=(X-μ)/σ
⇒ P(Z ≤ (23.5-24)/1.4) - P(Z ≤ (22-24)/1.4) = P(Z ≤-0.36) - P(Z ≤ -1.43)
Now you look at the table of the Z-distribution for the cumulative probabilities for both z-score
⇒ (1 - 0.6406) - (1 - 0.9236)
⇒ 0.3594- 0.0764 = 0.2830
Hence, the required proportion of red drum fish would be 0.2830 between 22 and 23.5 inches in length.

write the quadratic equation that has a Vertex at -4, negative 1 includes the point -2, 1
Answers
y = (1/2)(x + 4)^2 - 1
Explanation:
Start with the general quadratic equation in vertex form:
y = a(x - h)^2 + k
The vertex is at (h, k).
* Remember that -h is shown in the equation.
Substitute the information from the question into the general equation.
x = -2
y = 1
h = -4
k = -1
y = a(x - h)^2 + k
1 = a(-2 - (-4))^2 + (-1)
Simplify and isolate “a”
1 = a(-2 + 4)^2 - 1
1 = a(2)^2 - 1
1 = 4a - 1
4a = 2
a = 2/4
a = 1/2
Rewrite the general equation with values for “a”, “h” and “k”.
y = a(x - h)^2 + k
y = (1/2)(x + 4)^2 – 1
solve
z = 6 π x y

3v + 11 = 50 what’s the answer ?
Answers
Answer:
v=13
Step-by-step explanation:
3(13) = 39+11 = 50
Answer:
Our main goal is to isolate the variable here (v).
And if we want to solve this equation,
we must utilize inverse operations.
Given that:-
3v + 11 = 50
We always first get rid of the constants.
And in this case, 11 is our constant.
So the inverse operation of addition is subtraction (because 11 is being added)
-11 -11
3v = 39
Now, we are left with a co-efficient.
To isolate v, we must apply the inverse operation of multiplication which is division (because 3 and 'v' are being multiplied).
/3 /3
V = 13

The perimeter of a rectangular room is 32m.The length of a diagonal is 8m more than than the width.Find the dimensions of the room.
Answers
Answer: 12m by 4m.
Step-by-step explanation: You are looking for the dimensions of the room here, also known as the length and width.
Let’s make width equal to x since we don’t know what the value is. Length is going to be x + 8 since the diagonal is 8m MORE than the width.
w = x
l = x + 8
Use the equation for the perimeter.
P = 2l + 2w
Plug in your values:
32 = 2(x + 8) + 2(x)
Now, solve for x! First start by distributing the 2:
32 = 2x + 16 + 2x
Next, add like terms:
32 = 4x + 16
Subtract 16 from both sides:
16 = 4x
Divide by 4 on both sides:
4 = x
Now we have x, but remember, x is equal to the width. We just solved for width so now we need length.
l = x + 8
Plug in your x and solve:
l = 4 + 8
l = 12
Your length is 12m and your width is 4m, therefore, the dimensions of the rectangular room are 12m by 4m.
What is the slope of a line perpendicular to the line whose equation is 2x-5y=-40
Answers
Answer:
[tex]2x-5y=-40\\-5y = -40-2x\\y = \frac{-40}{-5}-\frac{2x}{-5} \\y = \frac{2x}{5}+8[/tex]
Slope of a line perpendicular is [tex]\frac{-5}{2}[/tex]
Step-by-step explanation:
Hey there!
The given equation is ; 2x - 5y = -40.
Or, 2x - 5y + 40 = 0
Slope of the equation is;
[tex]slope(m) = \frac{ - coeff. \: of \: x}{coeff. \: of \: y} [/tex]
[tex]m = \frac{ - 2}{ - 5} [/tex]
[tex]m = \frac{2}{5} [/tex]
Therefore, the slope of equation is 2/5.
Now; For the perpendicular lines:
Slope of equation * slope of next line = -1
i.e M1*M2= -1
[tex] \frac{2}{5} \times m2 = - 1[/tex]
[tex]2 \: m2 = - 5[/tex]
[tex]m2 = \frac{ - 5}{2} [/tex]
Therefore, the slope of the line which is perpendicular line to 2x - 5y + 40= 0 is -5/2.

Then add the numerator. So 14/15
