Answer:
x° = 42°
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the useful relation ...
Cos = Adjacent/Hypotenuse
cos(x°) = 4.0/5.4
x° = arccos(4.0/5.4) ≈ 42.21°
The value of x is about 42.

The volume of the rectangular prism is 295.68 in. What is its width?
6.4 in.
11 in.
Answer: 4.2 in³
Step-by-step explanation: We already know the Height, Length, and he volume, but we don't know the width. To find the width:
1. Find the values. 295.68, 6.4, and 11 are all the values.
2. Multiply the Length and Height.
6.4 × 11 = 70.4
3. Calculate the Width by dividing the volume by the product of the length and height
295.68 ÷ 70.4 = 4.2
Hence, 4.2in³ is the missing width.
Let me know if you have any questions.

3. A kite is aloft at the end of a 1500 foot string. The string make an angle of 43° with the
ground. How far above the ground is the kite?
Do not calculate! Please provide your answer in calculator ready form. For example: h -
237cos(3129)
Answer:
[tex]h= 1500\,*\,sin(43^o)[/tex]
Step-by-step explanation:
Notice that there is a right angle triangle formed with sides as follows:
hypotenuse is the actual 1500 ft string. The acute angle 43 degrees is opposite to the segment that represents the height of the kite from the ground. Therefore, the trigonometric ratio that we can use to find that opposite side to the given angle, is the sine function as shown below:
[tex]sin(43^o) = \frac{opposite}{hypotenuse} \\sin(43^o) = \frac{opposite}{1500}\\opposite = 1500\,*\,sin(43^o)\\h= 1500\,*\,sin(43^o)[/tex]

Answer:
(-4,-4)
Step-by-step explanation:
Delta math
According to graph, the coordinates of the vertex of the parabola are (-4,-4).
What is parabola?"A parabola is a plane curve which is mirror-symmetrical and is approximately U-shaped."
Vertex of parabola"The vertex of a parabola is the point at the intersection of the parabola and its line of symmetry. For a parabola whose equation is given in standard form, the vertex will be the minimum (lowest point) of the graph and the maximum (highest point) of the graph.
After analysing the graph, the vertex of the parabola are (-4,-4)

(4n+1)(2n+6) multiply polynomials
Answer:
= 8n^2 +26n +6
Step-by-step explanation:
(4n+1)(2n+6)
= 8n^2 + 24n +2n +6
= 8n^2 +26n +6
The product of the polynomials (4n+1)(2n+6) is 8n² + 26n + 6.
To multiply the polynomials (4n+1)(2n+6), you can use the distributive property.
(4n+1)(2n+6) = 4n x 2n + 4n x 6 + 1 x 2n + 1 x 6
Applying the distributive property and simplifying each term:
= 8n² + 24n + 2n + 6
Combining like terms:
= 8n² + 26n + 6
Therefore, the product of the polynomials (4n+1)(2n+6) is 8n² + 26n + 6.

The floor area of a rectangular room is represented by x2 + 3xy – 10y2. What could the length and width be?
Answer:
The length is x + 5y
The width is x - 2y
But see below.
Step-by-step explanation:
Remark
The point of this question is to factor the trinomial. It can be factored.
(x 5y)(x 2y )
has to be the beginning of the factoring process.
(x - 5y)(x + 2y) The signs are right. The factoring isn't. The middle term has to be plus.
(x + 5y)(x - 2y)
The length is x + 5y
The width is x - 2y
x must be larger than 2y, otherwise you will get a negative width. That cannot be right.

Stefan sells Jin a bicycle for $125 and a helmet for $18. The total cost for Jin is 130% of what Stefan spent originally to buy the bike and helmet. How much did Stefan spend originally? How much money did he make by selling the bicycle and helmet to Jin?
PLEASE TELL ME AN ANSWER, THIS TEST IS DUE IN 5 MINUTES.
Answer: The selling cost for Stefan bicycle = $114 and
the selling cost of a helmet = $18.
The total cost for Jin is 120% of the money spent.
Let us assume purchasing cost of a bicycle = $x.
Purchasing cost of a halmet = $y.
For bicycle
120% of x is $114
=> 1.20 × x = 114
Dividing both sides by 1.20, we get
x=$95.
For helmet.
120% of y is $18.
=> 1.20 × y = 18.
Dividing both sides by 1.20, we get
y = $15.
Therefore, Stefan spent originally to buy a bike $95 and $15 to buy a helmet.
$114 - 95 = $19
$18 - 15 = $3.
Therefore, he made $19 by selling the bicycle and $3 by selling the helmet to Jin.
