Answer:
5 < x < 21
Step-by-step explanation:
The shortest would be if the 8 leg folded back on the 13 leg
13 - 8 > 5
The logest would be if the 8 leg extended the 13 leg
13 + 8 < 21
Therefor
5 < x < 21
An equation is shown.
x^3 = 125

What is 2 over 5 x 5 over 8
Answer:
the answer is 1/4
Step-by-step explanation:
2/5 × 5/8
2× 5/ 5 × 8
= 10/40
=1/4
Answer:
1/4
Step-by-step explanation:
You would do 2/5 times 5/8 which would equal 10/40 cause 5 times 2 is 10 and then 5 times 8 is 40 and then you would simplify the fraction 10/40 which would make it 1/4

Use the function f(x) to answer the questions:
f(x) = 2x2 − 5x + 3
Part A: What are the x-intercepts of the graph of f(x)? Show your work. (2 points)
Part B: Is the vertex of the graph of f(x) going to be a maximum or a minimum? What are the coordinates of the vertex? Justify your answers and show your work. (3 points)
Part C: What are the steps you would use to graph f(x)? Justify that you can use the answers obtained in Part A and Part B to draw the graph. (5 points)
Answer:
part A: x= 1 and x= 3/2
part B: minimum at (5/4, f(5/4))
Step-by-step explanation:
part A: factoring
0 = 2x^2 - 5x + 3
= (2x^2 - 2x)(-3x + 3)
= 2x(x - 1) -3(x-1)
= (2x - 3)(x - 1)
x= 1 and x= 3/2
part B: candidates test
find the derivative of the function.
f(x) = 2x^2 - 5x + 3
f'(x) = 4x -5
solve for critical numbers.
0 = 4x - 5
x = 5/4
candidates test by plugging in numbers into the derivative to see if that area is negative or pos.
f has a minimum at x = 5/4 because f' goes from neg to pos there. to find the coordinate for x = 5/4 just plug it into the original function to find f(5/4).
Part C: to draw the graph, I'd just plot the vertex coordinate that you solved for in part B, then I would plot the x intercepts that you solved for in part a, from there just draw a line throu the 3 points. (it should look like a U shape)

Trigonometry!!
==========================================================
Explanation:
We are told that quadrilateral ABCD is similar to quadrilateral EFGH.
The order of the four letter sequence is important.
For ABCD, we have AB as the first pair of letters. For EFGH, we have EF as the first pair of letters.Therefore, AB and EF are corresponding sides.
So AB = 10 and EF = x pair up together. We can form the ratio AB/EF which becomes 10/x.
The diagram shows that AD = 8. Notice that A and D are the first and last letters of ABCD. The first and last letters of EFGH are E and H. We can see that AD and EH correspond to one another because of this.
AD = 8 and EH = 6 forming the ratio AD/EH = 8/6
Because the quadrilaterals are similar, the corresponding ratios must be the same. Therefore, AB/EF is the same as AD/EH.
-----------------------
Let's set up a proportion to solve for x
AB/EF = AD/EH
10/x = 8/6
10*6 = x*8
60 = 8x
8x = 60
x = 60/8

Suppose that Theta is an angle in standard position whose terminal side intersects with the unit circle at (21/29,20/29). Fine the exact values of cscTheta, cosTheta, and cotTheta
Answer:
The coordinates of the vertex is:
x = 21/29, y = 20/29Horizontal leg = x, vertical leg = 20/29, hypotenuse = 1 (radius of unit circle)
csc θ = hypotenuse / opposite = 1 / (20/29) = 29/20 cos θ = adjacent / hypotenuse = (21/29) / 1 = 21/29cot θ = adjacent / opposite = (21/29) / (20/29) = 21/20Please help me find volume for this pyramid I'm having trouble.

find the surface area, and please show me steps so i can understand this myself !
Answer:
The surface area of the triangular prism is approximately 401.582 square feet.
Step-by-step explanation:
The figure represents a triangular prism, the procedure for calculating the surface area of the entire figure consists in adding the areas of each face (3 rectangles and 2 triangles):
[tex]A = 2\cdot \left[\frac{1}{2}\cdot (9\,ft)\cdot (4\,ft)\right] + (16\,ft)\cdot (4\,ft) + (9\,ft)\cdot (16\,ft) + (16\,ft)\cdot \sqrt{(9\,ft)^{2}+(4\,ft)^{2}}[/tex][tex]A \approx 401.582\,ft^{2}[/tex]
The surface area of the triangular prism is approximately 401.582 square feet.
If 2/3 is multiplied by a fraction greater than 1, which of these could be the product?
Answer:
Any number bigger than 2/3
Step-by-step explanation:
btw, I didn't see the options but here's the explanation
When you multiply by a part of a whole, a fraction, you are getting smaller. When you multiply by a number bigger than one, your product gets bigger. So, any number bigger than 2/3 works just fine

1) Solve for Side A
2) Solve for Angle B
Answer:
1) 42.51
2) 39.76
Answer:
solution given;
let
AB=a
AC=b=30ft
AB=c=20ft
<A=115°
By using Cosine rule.
a²=b²+c²-2bc cos angle
a²=30²+20²-2*30*20 Cos 115°
a²=1807.1419
a=√[1807.1419]
a=42.51
Side A is 42.51ft.
Again
Cos B=[tex] \frac{a²+c²-b²}{2ac} [/tex]
Cos B=[tex] \frac{42.51²+20²-30²}{2*42.51*20} [/tex]
Cos B=0.7687
<B=Cos -¹(0.7687)
<B=39.46°
Angle B is 39.46
Look at the drawings of two cylinders filled to the same level with water. The cylinders are identical in size and shape. Also shown at the right are two marbles, one glass and one steel. The marbles are the same size but the steel one is much heavier than the glass one. When the glass marble is put into Cylinder 1 it sinks to the bottom and the water level rises to the 6th mark. If we put the steel marble into Cylinder 2, the water will rise *
a. to the same level as it did in Cylinder 1
b. to a higher level than it did in Cylinder 1
c. to a lower level than it did in Cylinder 1
The density of a substance is its ratio of its mass to its volume. This determines the mass of the substance. The appropriate option to the question is:
b. to a higher level than it did in Cylinder 1.
The density of a mass determines the volume of liquid that would be displaced when put in a liquid. This is known as the Archimedes principle. It relates the mass of a material to its volume.
The density of the steel marble is more than that of the glass, thus it is expected that the liquid should rise above that of cylinder 1. Because the steel marble would displace more volume of water than the glass marble.
The given cylinders have equal measures and size, and contains the same volume of water. Thus, the water should rise to a higher point compared to that of cylinder 1.
Therefore the required answer is: b. to a higher level than it did in Cylinder 1.
