Answer:
B = 114°
Step-by-step explanation:
As A and B are angle in a parallel line.
So, A + B = 180°
6x - 48° + 4x + 38° = 180°
10x - 10° = 180°
x - 1° = 18°
x = 19°
Hence, Angle B = 4x + 38° = 76° + 38° = 114°
B= 75.6
Explanation:
Adding A and B gives 180.
Therefore,
B=180-A
B=180 - (6x-48)
B=132-6x ———(1)
Given in Question B=4x+38, ———(2)
4x+38 = 132-6x
(Group like terms on each side to find x)
4x+6x=132-38
10x = 94
x=94/10
x= 9.4
Therefore,
B = 4(9.4) + 38
=75.6 (degrees)

Determine which graph, f(x) = or g(x) = 16, rises more steeply. Explain.
Answers
Answer:
Sample Response: g(x) rises more steeply than f(x) because the value of a in f(x) is 4, whereas the value of a in g(x) is 16. This means that f(x) is a vertical stretch of the square root function by a factor of 4, while g(x) is a vertical stretch of the square root function by a factor of 16. Both functions will contain the point (0, 0), but f(x) would contain the point (1, 4) and g(x) would contain the point (1, 16), which is a steeper rise from the point (0, 0).

Caleb and Sergio stacked boxes on a shelf. Caleb lifted 14 boxes of equal weight. Sergio lifted 12 boxes of equal weight, but Sergio's boxes each weighed 10 lb more than Caleb's boxes.
Together they lifted a total of 354 pounds.
What was the weight of one of Caleb's boxes?
Answers
Answer:
Step-by-step explanation:
Caleb = 14x
Sergio = 12y
Sergio's boxes each weighed 10 lb more than Caleb's boxes.
y = x + 10
The equation is
14x + 12y = 354
Substitute y = x + 10
14x + 12(x+10) = 354
14x + 12x + 120 = 354
26x = 354 - 120
26x = 234
Divide both sides by 26
x = 234/26
= 9
x = 9lb
Recall,
y = x + 10
= 9 + 10
y = 19lb
Check:
14x + 12y = 354
14(9) + 12(19)
= 126 + 228
= 354
Answer: 19lb

Find u in terms of m,g and v in this equation E = m/2g(v²-u²)
Answers
Step-by-step explanation:
E = m/2g(v²-u²)
2g×E = 2g×m/2g(v²-u²)
2Eg = m(v²-u²)
2Eg = mv² - mu²
mu²= mv² -2Eg
mu²/m = mv² -2Eg /m
u²= v² -2Eg

Answers
Answer:
9
Step-by-step explanation:
The first thing we shall be doing here is substituting f(x) into g(x).
Mathematically, that would be written as g(f(x))
= 2(4x-3)-1 = 8x -6 -1 = 8x - 7
Now we shall find g(f(2)) by substituting 2 into the expression above.
Mathematically, that would be 8(2) -7 = 16-7 = 9
* Anyone please give me some information about the following;
• About cone and conic section.(with diagram)
• Describe how are cones, ecllipse, parabola, hyperbola are formed?
(I need full information as much as possible)
Thank you!
Answers
Answer: See explanation below
Step-by-step explanation:
A conic is a curve obtained as the intersection of the surface of a cone with a plane. The 4 types of conic section are: 1. Hyperbola 2. The Parabola 3. The Ellipse and 4. Circle.
Hyperbola: When the plane cuts the cone at an angle closer to the axis than the side of the cone a hyperbola is formed.
Cones: A cone is a three-dimensional shape that goes in a diagonal directions from a flat base to a point called the apex or vertex. A cone is formed by a set of line segments connecting from the base to the apex.
Parabola: A parabola is the curve formed by the intersection of a plane and a cone, but only when the plane is at the same slope as the side of the cone.
Ellipse: An ellipse is formed by a plane intersecting a cone at an angle to its base. All ellipses have two focal points and a center and a major and minor axis.
Circles: A circle is formed when the plane is parallel to the base of the cone.
*Note: Some of these answers are PLAGIARISED from the internet as I looked these up and copied & pasted some information, so please paraphrase if turning this in.*
Answer: see below
Step-by-step explanation:
Types of Conics are: Circles, Ellipses, & Hyperbolas.
Here is information about each one:
Circle: Two parabolas facing each other. Distance from the center to the vertices are exactly the same.
(x - h)² + (y - k)² = r²
(h, k) is the center of the circler is the radius of the circleThe 4 vertices are: (h, k+r), (h, k-r), (h + r, k), & (h - r, k)Ellipse: Two parabolas facing each other. Distance from the center to the vertices are not the same.
(x - h)²/a² + (y - k)²/b² = 1
(h, k) is the center of the ellipsea is the horizontal distance from the center to the vertices/co-verticesb is the vertical distance from the center to the co-vertices/verticesIf a > b, then vertices are: (h+a, k), & (h-a, k) and co-vertices are (h, k+b), (h, k-b)If b > a, then the vertices and co-vertices are reversed Use |a² - b²| = c² to find the distance from the center to the foci. If a > b, then Foci = (h+c, k) & (h-c, k). If b > a, then ± from the k-valueExample: (x - 1)²/9 + (y - 2)²/25 = 1
Center (h, k) = (1, 2) a = √9 = 3 b = √25 = 5
Vertices (b > a): (1, 2+5) & (1, 2-5) ==> (1, 7) & (1, -3)
Co-vertices: (1+3, 2) & (1-3, 2) ==> (4, 2) & (-2, 2)
Foci (b > a): c = √(25-9) = 4 --> (1, 2+4) & (1, 2-4) ==> (1, 6) & (1, -2)
Hyperbola: Two parabolas facing AWAY from each other. Distance from the center to the vertices may or may not be the same.
(x - h)²/a² - (y - k)²/b² = 1 or (y - k)²/b² - (x - h)²/a² = 1
↓ ↓
opens left and right opens up and down
(h, k) is the center of the hyperbolaIf x²-y², then vertices are: (h+a, k), & (h-a, k). There are NO Co-vertices.If y²-x², then vertices are (h, k+b), (h, k-b). There are NO Co-vertices.Use a² + b² = c² to find the distance from the center to the foci. If x²-y², then Foci = (h+c, k) & (h-c, k). If y²-x², then ±c from the k-valueThe slope of the asymptotes are ± b/a and pass through the center (h, k)Example: (x - 1)²/9 - (y - 2)²/16 = 1
Center (h, k) = (1, 2) a = √9 = 3 b = √16 = 4
Vertices (x²-y²): (1+3, 2) & (1-3, 2) ==> (4, 2) & (-2, 2)
Foci (x²-y²): c = √(9 + 16) = 5 --> (1+5, 2) & (1-5, 2) ==> (6, 2) & (-4, 2)
Asymptotes: m = ± 4/3 through (h, k) = (1, 2) ==> y = ± 4/3(x - 1) + 2
