Find the value of each variable
Answer:
x = 16[tex]\sqrt{3}[/tex]
y = 8[tex]\sqrt{3}[/tex]
Step-by-step explanation:
For this type of equation, you are going to use the following trigonometric signs tangent and cosine. Tangent is used for the y-variable and cosine is used for the x-variable. For the y-variable, it is 24 tan 30 to get 8 root 3 as your answer. For the x-variable, you would get ([tex]\sqrt{3}[/tex] / 2)x = 24. Divide that root number to get 16[tex]\sqrt{3}[/tex] as your x variable.
Answer: 16 sqrt 3. 8 sqrt 3

if f(x)=√2x+3/6x-5, then f(-1/2)=
answere=-1
this is the answere and the explanation.
By substituting x = -1/2, the expression [tex]\(f(x) = \frac{\sqrt{2x} + 3}{6x - 5}\)[/tex] can be simplified to[tex]f(x) = \(f(-\frac{1}{2}) = \frac{\sqrt{3 - \sqrt{2}}}{-8}\).[/tex].
To find [tex]\(f(-\frac{1}{2})\)[/tex], substitute [tex]\(-\frac{1}{2}\)[/tex] into the function f(x):
[tex]\(f(-\frac{1}{2}) = \frac{\sqrt{2 \cdot (-\frac{1}{2}) + 3}}{6 \cdot (-\frac{1}{2}) - 5}\)[/tex]
Now, simplify the expression inside the square root:
[tex]\(f(-\frac{1}{2}) = \frac{\sqrt{-\sqrt{2} + 3}}{-3 - 5}\)\\\(f(-\frac{1}{2}) = \frac{\sqrt{3 - \sqrt{2}}}{-8}\)[/tex]
So, [tex]\(f(-\frac{1}{2}) = \frac{\sqrt{3 - \sqrt{2}}}{-8}\)[/tex].

A bottle is 2 litre mennu drank 1/8.How many did neenu drink
Answer:
Volume drank by Mennu = 250 ml
Step-by-step explanation:
Given:
Volume of bottle = 2 liter = 2000 ml
Mennu drank = 1/8 of bottle
Find:
Volume drank by Mennu
Computation:
Volume drank by Mennu = Volume of bottle x Mennu drank
Volume drank by Mennu = 2,000 x 1/8
Volume drank by Mennu = 250 ml
1) Graph by making a
table.
y=1/2x+2
Answer:
Below.
Step-by-step explanation:
You can use any 4 x values, so we could have:
- 2 0 2 4
Now find the corresponding y values by substitution in the equation:
For x = -2, y = 1/2 *-2 + 2 = 1.
For x = 0, y = 1/2 * 0 + 2 = 2.
For x = 2 , y = 1/2* 2 + 2 = 3.
For x = 4 , y = 1/2 * 4 + 2 = 4.
So the table is:
-2 0 2 4
1 2 3 4
You then plot the points (-2, 1), (0, 2), (2, 3) AND (4, 4) on the grid and draw a line through them The graph will be a straight line.

If TUV is translated to image T'U'V , as shown below , by the rule (x,y) -> (x+8, y-3) what are the coordinates or TUV ?
Answer:
D) is the answer
Step-by-step explanation:
ohh ok i understand TUV is (x,y)
so (x+8,y-3) is the T'U'V
so subtract 8 and add 3 to this translation
(x-8,y+3)
looking at U
t goes to (10,-5)
and that is the only one so the answer is D
The coordinates or TUV are (-6,-3),(-1,6),(0,-2), the correct option is C.
How does dilation affect length, area, and volume of an object?(SCALING ZOOMING SIMILAR FIGURES)
Suppose a figure (pre image) is dilated (dilated image) by scale factor of k.
So, if a side of the figure is of length L units, and that of its similar figure is of M units, then:
L = k × M
where 'k' will be called as scale factor.
The linear things grow linearly like length, height etc.
The quantities which are squares or multiple of linear things twice grow by square of scale factor. Thus, we need to multiply or divide by k² to get each other corresponding quantity from their similar figures' quantities.
So area of first figure = k² × area of second figure
Similarly,
Volume of first figure = k³ × volume of second figure.
It is because we will need to multiply 3 linear quantities to get volume, which results in k getting multiplied 3 times, thus, cubed.
Given;
TUV is translated to image T'U'V , as shown below , by the rule (x,y) -> (x+8, y-3)
Coordinates of T'U'V; (2,-6),(7,3),(8,-5)
Now, coordinates of TUV;
T coordinate=(-6,-3)
U coordinate=(-1,6)
V coordinate=(0,-2)
Therefore, coordinates before dilation will be (-6,-3),(-1,6),(0,-2)

Mark glues together four pieces of wood to make one long strip. The pieces measure 16.75 inches, 9 inches, 24.25 inches, and 12.5 inches. How long is the strip of wood?
Given that,
Length of 4 pieces of wood are 16.75 inches, 9 inches, 24.25 inches, and 12.5 inches.
To find,
The length of the strip of wood.
Solution,
Mark glues together four pieces of wood to make one long strip.
Long strip = The sum of 16.75 inches, 9 inches, 24.25 inches, and 12.5 inches.
L = 16.75 + 9 + 24.25 + 12.5
= 62.5 inches
Hence, the strip of wood is 62.5 inches long.

identify the slope in y=-x
Answer:
m = -1
Step-by-step explanation:
y = -x can also be written as
y = -1x + 0
The slope is -1.
In slope intercept equations, if the slope is '1' or '-1' they would usually drop the one.
Hope this helps.
Answer:
the slope of the line y = -x will be: m = -1
The line graph is also attached below.
Step-by-step explanation:
The slope-intercept form of the line equation
[tex]y = mx+b[/tex]
where
m is the slope and b is the y-interceptGiven the line
[tex]y = -x[/tex]
comparing with the slope-intercept form of the line equation
The slope = m = -1The y-intercept = b = 0Therefore, the slope of the line y = -x will be: m = -1
