A figure that, showing 4 lines a,b,c and d.Angle between line b and c is (4x-10)°Angle between line b and c is 58°.To find
True statements that prove the lines a and b are parallel.So according the question
We have
Angle between line a and c = m∠1Angle between line a and d = m∠1Angle between line b and c = (4x-10)°Angle between line b and d = 58°Angle between line c and d = (3x-1)There are two angles from the c and d lines with the lines a and b being equal that can be used to determine whether the lines a and b are parallel.
That's mean
Angle between line a and c = Angle between line b and cm∠1 = (4x-10)°
Angle between line a and d = Angle between line b and dm∠2 = (58)°
m∠2 = 58°

Ratios Equivalent to 15:6 (not 6:15)
Pls tell me what ratios they are
Answers
Answer:
30/32
Step-by-step explanation:
15×2=30
16×2=32
30/32
Answer:
5:2 , 30:12 , 60:24 , etc.
Step-by-step explanation:
To identify ratios equivalent to 15:6, all you need to do is multiply or divide both numbers in the ratio by the same amount to find an equivalent ratio.
So, for example:
1:2 --> 1*2 : 2*2 = 2:4 Both one half, so equal.
Now for 15:6...
Let's divide by the least common denominator ( 3 )
15 / 3 and 6 / 3 = 5 and 2
So 15:6 = 5:2
And we can also multiply the ratio by any constant as well...
For example 15 * 2 and 6 * 2
So 30:12 = 15:6

Answers
The coordinates of the mid point of the given points (4,-1) and (3,-2) is found as (x,y) = (3.5, -1.5).
What exactly is the Mid - Point Theorem?The midpoint of a line segment is referred to by the midpoint theorem. It describes the coordinate points of the line segment's midpoint and can be found by averaging the coordinates of a given endpoints.It also states that a line with endpoint coordinates - [x(1), y(1)] and [x(2), y(2)] has its mid - point just at coordinate.In response to the question, we have -
A (4,-1)and B(3,-2) are our two coordinate points.
We must determine the midpoint of the this line AB.
x(m) = [x(1) + x(2)]/2
y(m) = [y(1) + y(2)]/2
A is the first coordinate point (4,-1).
Point B is the second coordinate (3,-2).
Put the given points;
x(m) = [4 + 3)]/2
x(m) = 7/2 = 3.5
Now, for y;
y(m) = [y(1) + y(2)]/2
y(m) = [-1 -2]/2
y(m) = -3/2 = -1.5
Therefore, we get - using the Mid - Point formula (x,y) = (3.5, -1.5).

Answer:
Angle BOC = 120°
Angle DOC = 60°
Angle ODC = 90°
Step-by-step explanation:
Triangle ABC is an equilateral triangle, therefore Angle BAC = 60°.
Now that we know Angle BAC, we can find Angle BOC: 2 × 60 = 120°
Angle DOC = ½ Angle BOC ( Radius drawn from centre to midpoint of chord, bisect the angle)
So Angle DOC = ½ (120) = 60°
Angle = 90° because D is the midpoint of chord BD and OD is a radius.

Find a vector function that represents the curve of intersection of the two surfaces. the paraboloid z = 8x 2 y 2 and the parabolic cylinder y = 3x 2 r(t) = t i j
Answers
The vector function, r(t) that represents the curve of intersection of the two surfaces, the paraboloid and the parabolic cylinder is given by < t, 3t2, 8t2 + 9t4 >. It is attained by applying the concept of vectors to the assigned problem.
What is a vector?
A vector is any quantity that contains both magnitudes as well as direction. Geometrically, one can imagine a vector as a directed line segment, whose length denotes the magnitude of the vector and the direction is shown by the arrow, which is generally taken from its tail to its head. Using an arrow with a line specifies that it is not only scalar but also has some direction.
Calculation of the vector function representing the curve of intersection of the paraboloid and parabolic cylinder
A vector function r(t) is represented as: r(t) = < x, y, z >
Given: y = 3x2 – 1
z = 8x2 + y2 – 2
Let,
x = t
Using x = t in equations 1 and 2
y = 3t2
z = 8t2 + y2
Putting the value of y in z, we get,
z = 8t2 + (3t2)2
z = 8t2 + 9t4
Substitute these values of x, y, and z in vector representation to obtain the result, i.e. < t, 3t2, 8t2 + 9t4 >
Hence, the value of vector function r(t) is: < t, 3t2, 8t2 + 9t4 >

estimate the square root to the nearest tenth the square root of 11, and the square root of 62
Answers
The square root of 11 and 62 to the nearest tenth is 7.9 and 3.3 .
Given, the numbers are 11 and 62.
we are asked to determine the square root of the given numbers to the nearest tenth.
a. 11
Since the given number is not an even number, hence we can't get a whole number as the square root of 11.
we need to find the number whose square root is nearest to the number 11.
3 × 3= 9
9 is nearer to 11 whereas 4 × 4 = 16 gets greater than 11.
then dividing the number 11 by 3.we get:
√11 = 3.31662479 × 3.316622479
√11 = 3.31662479
√11 = 3.4 (rounding off to the nearest tenth)
b. 62
since we can't get the square root as a whole number so ,
we need to find the number whose square root is nearest to the number 62.
8 × 8 = 64
which gets greater than 62, hence we take 7 × 7 = 49
therefore, √62 = 7.874007874 × 7.874007874
√62 = 7.874007874
√62 = 7.9 (rounding off to the nearest tenth)
hence we get the square root of 11 and 62 as 3.3 and 7.9 respectively.

f ( x ) = - x² - 64 - 16 x - 1
f ( x ) = - x² - 16 x - 65

The equation of straight line in the cartesian plane with slope and y-intercept of -1 is y+x+1=0
A straight line is an object in geometry that is indefinitely long and has neither breadth nor depth nor curvature.
The x-axis, a horizontal line, and the y-axis, a vertical line, are two perpendicular lines that split the number plane, also known as the Cartesian plane, into four quadrants. The origin is the location where these axes converge.The general equation of a line in the cartesian plane is given by the equation y = mx + c , where m is the slope and c is the y-intercept.The slope of a straight line is calculated by taking tan θ where θ is the angle made by the line with positive direction of x- axis.Given the slope = y-intercept= -1
Therefore m = -1 and c = -1 .
Substituting the values of m and c in the general equation of a straight line we get :
y = -x - 1
or, y + x+ 1 = 0
Therefore the equation of the straight line is y + x+ 1 = 0.
