Answer:
AB = 12.99
Step-by-step explanation:
To answer this problem, use the breast theorem.
[tex]\frac{sinA}{a} = \frac{sinC}{c}[/tex]
The side opposite angle C is denoted by the letter c. It is also denoted as AB side
We know that:
A = 80.4°
a = 17
C = 48.9
Then we have that:
[tex]\frac{sin(80.4\°)}{17} = \frac{sin(48.9\°)}{c}[/tex]
Now clear the variable c from the equation
[tex]c = \frac{sin(48.9\°)}{\frac{sin(80.4\°)}{17}}[/tex]
[tex]c = 12.99[/tex]

Find the volume of the figure: an oblique cylinder next to a cube.
Answer:
[tex](2,200\pi +8,000)\ ft^{3}[/tex]
Step-by-step explanation:
we know that
The volume of the figure is equal to the volume of cube plus the volume of the cylinder
step 1
Find the volume of the cube
The volume of the cube is equal to
[tex]V=b^{3}[/tex]
we have
[tex]b=2(10)=20\ ft[/tex] ----> the length side of the cube is equal to the diameter of the cylinder
so
[tex]V=20^{3}=8,000\ ft^{3}[/tex]
step 2
Find the volume of the cylinder
The volume of the cylinder is equal to
[tex]V=\pi r^{2} h[/tex]
we have
[tex]r=10\ ft[/tex]
[tex]h=42-20=22\ ft[/tex]
substitute
[tex]V=\pi (10)^{2} (22)[/tex]
[tex]V=2,200\pi\ ft^{3}[/tex]
step 3
The volume of the figure is equal to
[tex](2,200\pi +8,000)\ ft^{3}[/tex]
The volume of the figure = volume of oblique cylinder + volume of cube = 2,200π + 8,000 cubic feet.
What is the Volume of an Oblique Cylinder?Volume of oblique cylinder = πr²h [radius of cylinder = r].
The volume of the figure = volume of oblique cylinder + volume of cube = πr²h + s³
Given the following:
s = 2(10) = 20 ftr = 10 fth = 42 - 20 = 22 ftPlug in the values into πr²h + s³:
The volume of the figure = π(10²)(22) + 20³

What is the value of y in the product of powers below?
Answer:
y =0
Step-by-step explanation:
From the equation;
8³ × 8⁻⁵×8^y = 8⁻²= 1/8²
From the laws of indices;
aⁿ×aⁿ = a^2n
Therefore;
8³ × 8⁻⁵×8^y = 8^(3+-5+y)
8^(-2+y) = 8^-2 ; but the bases are the same and thus the exponents are the same;
-2 + y = -2
y = 0
Answer:
The value of y is 0
Step-by-step explanation:
8³ * 8^-5*8^y = 8^-2 or 1/8²
Taking indices of both sides
From first law of indices;
Multiplication sign change to addition; i.e. x^a * x^b = x^(a + b).
So,
8³ * 8^-5*8^y = 8^-2
Becomes
8^(3 + (-5) + y) = 8^-2
Same base of 8 can cancel one another. So, we're left with
3 + (-5) + y = -2
Open the bracket
3 - 5 + y = -2
-2 + y = -2
Make y the subject of formula
y = 2 - 2
y = 0
Hence, the value of y in the equation is 0
Express the area of a rectangle with length 4x^34x
3
4, x, start superscript, 3, end superscript and width 555 as a monomial.
The awnser is 20 x 3
Hope this helps!
The area of a rectangle with length 4x^3 and width 5 is expressed as the monomial 20x^3 by multiplying the length and width.
To express the area of a rectangle as a monomial when given the length and width, we simply need to multiply these two dimensions together. In this case, the rectangle has a length of 4x^3 and a width of 5. The area (A) of a rectangle is given by the formula A = length * width.
So, the area of this rectangle can be calculated as:
A = 4x^3 * 5
Now, we multiply the numerical coefficients (4 and 5) and then combine them with the variable part:
A = (4 * 5) x^3
A = 20x^3
This expression, 20x^3, represents the area of the rectangle as a monomial

x = 7
Answer:
x equals six start fraction one over two end fraction
Step-by-step explanation:
Segments which are parallel have the same slope. Find the slope of of YZ. Then using that value, find the slope WX and solve for the value of x.
Slope of YZ is:
[tex]m = \frac{y_2-y_1}{x_2-x_1} = \frac{6-2}{5-2} =\frac{4}{3}[/tex]

a different lake currently has an area of 240 square km but is shrinking each year by 6% from the previous year's area. How much area will the lake have after 13 years?
The answer is:
[tex]A(13)=107.37Km^{2}[/tex]
Why?We can calculate the area of the lake after 13 years using the following equation:
[tex]A(t)=A(initial)(1-ShrinkingRate)^{t}[/tex]
Where,
A(t), is the area after t time (years)
A(Initial), is the initial area
Shrinking Rate, is the rafe of shrinking and it's 6% or 0.06.
t, is the time
So, substituting we have:
[tex]A(13)=240(1-0.06)^{13}=240*0.447=107.37Km^{2}[/tex]
So, the are after 13 years will be:
[tex]A(13)=107.37Km^{2}[/tex]

Answer:
7
Step-by-step explanation:
This is an equation of an ellipse of the form:
[tex]\frac{x^2}{a^2}+\frac{y^2}{b^2}=1[/tex]
Where a and b are the minor and major intercepts, given a<b
In this question, a<b and a = 3 and b = 7
The distance from the center to the major intercept is b, thus the distance we are seeking for is 7
Answer:
b = 7 units.
Step-by-step explanation:
The given equation of the ellipse is
[tex]\frac{x^{2} }{9} +\frac{y^{2} }{49}=1[/tex]
As we know in an ellipse [tex]\frac{x^{2} }{a^{2} }+ \frac{y^{2} }{b^{2}}=1[/tex]
a will be major axis and b is the minor axis when ( a > b )
In the given equation 49 > 9 ⇒ b² > a²
so major axis will be = √49
= 7
Therefore, distance from center to the major intercept is b = 7 units.
a line passing through the origin intersects the point -8 -5 what is the slope of the line
To find the slope of a line passing through the origin and a point, use the formula slope = (y2 - y1)/(x2 - x1). For a line passing through origin and the point (-8,-5), the slope is 5/8.
Explanation:The topic at hand revolves around the concept of slope and the algebra of straight lines. The slope is calculated by finding the change in y (vertical axis) over the change in x (horizontal axis). To find the slope of a line passing through the origin and the point (-8,-5), use the formula slope = (y2 - y1)/(x2 - x1).
In this case, the origin is point (0,0) and the given point is (-8,-5). So to find the slope, we substitute these values into the slope formula: slope = (-5 - 0)/(-8 - 0) = 5/8. Therefore, the slope of the line passing through the origin and the point (-8,-5) is 5/8.

the volume of a cylinder is 1,356.48^ feet. If the diameter is 12 feet, calculate the height of the cylinder.
Answer:
11.99 ft
Step-by-step explanation:
The formula for the volume of a cyl. of radius r and height h is V = πr²h.
Solving this immediately for h yields:
V
h = ----------
πr²
Inserting the known quantities results in:
V 1356.48 ft³
h = ---------- = ---------------------- Note that r = (1/2)d, so r = (1/2)(12 ft) = 6 ft
πr² 3.14159 (6 ft)²
= 11.994 ft
The height of the cyl. is 11.99 ft (to the nearest hundredth foot)
Final answer:
To find the height of the cylinder with a volume of 1,356.48 cubic feet and a diameter of 12 feet, divide the volume by the area of the base (calculated with a radius of 6 feet) to get approximately 11.99 feet.
Explanation:
To calculate the height of a cylinder when the volume and diameter are given, we use the formula for the volume of a cylinder, V = πr²h, where V is the volume, r is the radius, and h is the height. In this case, we have a volume of 1,356.48 cubic feet and a diameter of 12 feet, meaning the radius is 6 feet (half of the diameter). So we can plug these values into our formula to solve for h.
First, calculate the area of the base (πr²): 3.14159 × (6 feet)² = 3.14159 × 36 = 113.0976 square feet. Then we divide the given volume by this area to find the height: 1,356.48 cubic feet / 113.0976 square feet = 11.99 feet. Therefore, the final answer for the height of the cylinder is approximately 11.99 feet.

The graph of f(x + 2) is a vertical shift of f(x) = x3 two units down.
Answer:
C
Step-by-step explanation:
In translating graphs of functions, we can follow 2 rules:
1. The graph of [tex]f(x)+a[/tex] is the graph of [tex]f(x)[/tex] shifted a units UP VERTICALLY and the graph of [tex]f(x)-a[/tex] is the graph of [tex]f(x)[/tex] shifted a units DOWN VERTICALLY.
2. The graph of [tex]f(x+a)[/tex] is the graph of [tex]f(x)[/tex] shifted a units to the LEFT HORIZONTALLY and the graph of [tex]f(x-a)[/tex] is the graph of [tex]f(x)[/tex] shifted a units RIGHT HORIZONTALLY.
If we understand the 2 rules above, we clearly know that f(x+2) will be a horizontal shift to the LEFT, of course, with respect to the function [tex]f(x)=x^3[/tex]. Looking at the answer choices, C is right.

the sum of two numbers is 17. one number is 3 less than 2/3 of the other number. what is the lesser number?
the lesser number is 5.
steps:Let the first number = x
Let the second number = y
set up two equations
x + y = 17
2/3 x -3 = y
sub the second equation into the first one
x + 2/3 x - 3 = 17
collect like terms (1x = 3/3 x)
5/3 x - 3 = 17
add 3 to both sides
5/3 x = 20
multiply by 3 on both sides
5x = 60
divide by 5 on both sides
x = 12
sub back in one of the equations and solve to find the other number:
x + y = 17
12 + y = 17
y= 5
