Which line has the slope with the greatest value? A blue B purple C red D green
The line that has the slope with the greatest value is determined as the: A. Blue line.
How to Find the Slope of a Line?The slope of a line is the change in y over the change in x, which can also be calculated as:
Slope (m) = rise / run = y2 - y1 / x2 - x1.
Also, the steeper the slope, the greater the value of the slope that you will get, while the more gentle the slope, the smaller the value of the slope of the line we would get.
Out of the three lines shown in the graph, the steepest is the blue line, this means that it has the greatest slope value.

Quadrilateral ABCD is inscribed in a circle such that:
Answer:
∠ C = 84°
Step-by-step explanation:
A quadrilateral inscribed in a circle is a cyclic quadrilateral.
the opposite angles sum to 180° , that is
∠ A + ∠ C = 180 , then
x² + 60 + 8x + 36 = 180
x² + 8x + 96 = 180 ( subtract 180 from both sides )
x² + 8x - 84 = 0 ← in standard form
(x + 14)(x - 6) = 0 ← in factored form
equate each factor to zero and solve for x
x + 14 = 0 ⇒ x = - 14
x - 6 = 0 ⇒ x = 6
x > 0 , then x = 6 , so
∠ C = 8x + 36 = 8(6) + 36 = 48 + 36 = 84°

The bearing of the cruise ship displacement from its initial position is 15.06°, which makes the second option correct
What is bearing?Bearing is usually measured in degrees, with 0° indicating the reference direction (usually North), and increasing clockwise to 360°. It refers to the direction or angle between a reference direction and a point or object.
We will get a right triangle from travels of the ship, such that we can call the initial position A, the point after 8 miles B and the point after 30 miles C
angle B = 30° + 60° = 90°
AB = 8
BC = 30
by Pythagoras rule;
AC = √(8² + 30²) = 31.04
using sine rule;
30/sinA = 31.04/sin90
A = sin⁻¹[(30 × sin90)/31.04]
A = 75.06°
bearing from initial position = (30° + 75.06°) - 90°
bearing from initial position = 105.06 - 90°
bearing from initial position = 15.06°
Therefore, the bearing of the cruise ship displacement from its initial position is 15.06°

H

O
HJ = 0
X
Based on the figure, we can see that triangles OHJ and OIX are similar because they share the same angle at O and HI and HJ are tangent to the circle. Thus, we can set up the following proportion:
OH / OI = HJ / (HJ + 9)
Substituting the given values:
6.5 / 3.9 = HJ / (HJ + 9)
Cross-multiplying:
6.5(HJ + 9) = 3.9HJ
Distributing:
6.5HJ + 58.5 = 3.9HJ
Simplifying:
2.6HJ = -58.5
HJ = -22.5
However, this answer doesn't make sense in the context of the problem. Since HJ represents a length, it cannot be negative. Therefore, we need to re-examine our work.
Looking back at our proportion, we can see that the ratio of OH to OI is greater than 1, which implies that HJ is greater than 9. This makes sense since HJ is a chord of the circle and thus must be longer than the radius.
Let's try the problem again, but this time we'll rearrange the proportion to solve for HJ:
HJ / (HJ + 9) = OI / OH
Substituting the given values:
HJ / (HJ + 9) = 3.9 / 6.5
Cross-multiplying:
6.5HJ = 3.9HJ + 35.1
Simplifying:
2.6HJ = 35.1
HJ = 13.5
Therefore, HJ is equal to 13.5.

answer to the nearest whole number.
The new surface area is square millimeters.
The new surface area of the hemisphere-shaped mole would be = 102mm².
How to calculate the new surface area for the hemisphere-shaped mole?A hemisphere-shaped mole has a shape that has one surface that is curved and the other surface a flat circular base.
Since the surface area of one hemisphere has been given, the second hemisphere can be determined.
To calculate the new surface area of the hemisphere-shaped moles the following is carried out;
Radius of the initial mole = 5.7/2 = 2.85 mm
If 2.85mm radius = 51 mm²

The value of P(A∩B) rounding to the nearest thousandth, if necessary is: 0.086
How to solve probability problems?The parameters given are:
P(A) = 0.12
P(B) = 0.3
P(A ∪ B) = 0.334
We want to find the probability P(A∩B)
The P(A∪B) probability formula is given as:
P(A∪B) = P(A) + P(B) - P(A∩B)
where:
P(A) is Probability of event A happening
P(B) is Probability of event B happening
P(A∩B) is Probability of happening of both A and B.
Thus:
0.334 = 0.12 + 0.3 - P(A∩B)
P(A∩B) = 0.12 + 0.3 - 0.334

(x - h)^2 + (y - k)^2 = r^2
where (h,k) is the center of the circle and r is the radius.
Comparing this to the given equation, we see that the center of the circle is (-10,0) and the radius is sqrt(9) = 3.
The diameter of the circle is twice the radius, so:
diameter = 2(radius) = 2(3) = 6
Therefore, the diameter of the circle is 6.
We can write this in simplified, rationalized form as:

Find the sum of 3√5 and 4√25 in simplest form. Also, determine whether the result is rational or irrational and explain your answer.
The sum of 3√5 and 4√25 is an irrational number.
First, simplify the expressions inside the square roots:
3√5 = 3√(5×1) = 3√5
4√25 = 4√(25×1) = 4×5 = 20
Now, we add them together:
3√5 + 4√25 = 3√5 + 20
This is the simplest form since 20 is already a rational number and we cannot simplify the square root of 5 any further.
To determine whether the result is rational or irrational.
Since 3√5 is irrational and cannot be simplified any further, the expression as a whole is also irrational.
