Answer:
-8.5
Step-by-step explanation:
17/2 = 8.5
f = 8.5
f -1(17) = 8.5 -17 = -8.5
-8.5 is your answer
The value of [tex]f^{-1}(17)[/tex] is 2.
How to find the value of any inverse Function in x -From the definition of function we know that if f(x) = y , where x and y are two real values having range of (-∝,+∝) , then
[tex]f^{-1}(y) = x[/tex]
Thus in the problem, it is given that f(2) = 17 .
Using the above identity, we can find the value of [tex]f^{-1}(17)[/tex]
∴ [tex]f^{-1}(17) = 2[/tex]

The volume of a cuboid of length 8m and breadth 5m is 200 cubic meter. Find its height
Hey!!
Given,
Length(l)=8m
Breadth(b)=5m
Volume of a cuboid(V)=200 m^3
Height(h)=?
Now,
Volume of a cuboid=l*b*h
or,200=8*5*h
or,200=40h
or,h=200/40
h=5 meter
The height is 5 meter.
Hope it helps
Good luck on your assignment
Answer:
[tex]height = 5m[/tex]
Step-by-step explanation:
[tex]volume = l \times b \times h \\ 200 = 8 \times 5 \times h \\ 200 = 40h \\ \frac{200}{40} = \frac{40h}{40} \\ h = 5m[/tex]

Good luck on your assignment
Answer:
0.52
Step-by-step explanation:
→The formula for the volume of a cone is:
V = π[tex]r^2\frac{h}{3}[/tex]
→The "r," (radius) is half the diameter (1), so it's 0.5:
V = π[tex]0.5^2\frac{2}{3}[/tex]

A wall in Maria’s bedroom is in the shape of a trapezoid. The wall can be divided into a rectangle and a triangle. Using the 45°-45°-90° triangle theorem, find the value of h, the height of the wall.
Answer:
h = 13 ft
Step-by-step explanation:
The following information is missing:
The hypotenuse of that triangle is 13√2 ft.
The 45°- 45°- 90° triangle theorem states that the length of the hypotenuse is √2 times the length of the legs. This means that, in this case, the length of the legs are 13 ft. One of the legs is the height of the wall.

S
Answer:
s = [tex]\frac{3}{10}[/tex] m
Step-by-step explanation:
Given s varies directly with m then the equation relating them is
s = km ← k is the constant of variation
To find k use the condition s = 9 when m = 30 , thus
9 = 30k ( divide both sides by 30 )
k = [tex]\frac{9}{30}[/tex] = [tex]\frac{3}{10}[/tex]
s = [tex]\frac{3}{10}[/tex] m ← equation of variation

The following graph describes function 1, and the equation below it describes function 2. Determine which function has
a greater maximum value, and provide the ordered pair.
Function 1
Function 2
f(x) = -x2 + 2x - 3
Function 1 has the larger maximum at (1,4).
Function 1 has the larger maximum at (4,1).
Function 2 has the larger maximum at (1, -2).
Function 2 has the larger maximum at (-2, 1).
Answer:
the answer is function 1 has the larger max. at (4,1)
Step-by-step explanation:
draw function 2 : the vertex is (1,-2)
the vertex of function 1 is (4,1)
The function 1 has a greater maximum value than function 2, and the ordered pair is (1,4).
What is a function?Function is a type of relation, or rule, that maps one input to specific single output.
In mathematics, a function is an expression, rule, or law that describes the relationship between one variable (the independent variable) and another variable (the dependent variable) (the dependent variable). In mathematics and the physical sciences, functions are indispensable for formulating physical relationships.
Linear function is a function whose graph is a straight line
We are given that;
f(x) = -x2 + 2x - 3
Now,
To find the maximum value of a function, we can use the vertex form of a quadratic equation, which is y=a(x−h)2+k
, where (h,k) is the vertex of the parabola. The maximum value of the function is the y-coordinate of the vertex.
For function 1, we can rewrite it as [tex]$$f(x) = -(x-1)^2 + 4$$[/tex]
by completing the square. This means that the vertex of function 1 is (1,4) and the maximum value is 4.
For function 2, we can rewrite it as
[tex]$$f(x) = -\frac{1}{4}(x+2)^2 - 2$$[/tex]
by completing the square. This means that the vertex of function 2 is (−2,−2) and the maximum value is -2.
Therefore, by the given function answer will be (1,4).

20. Is the is the combined mass of 2 red-footed macaws and three blue and gold macaws closer to 3 kilograms or 4 kilograms? explain
the graph helps!! pls answer asp
Answer:
Step-by-step explanation:
First find total the weight of all red footed macaws whic is 525(2)=1050
and then the blue and gold macaws 800(3)= 2400
So add them both together yu get 3450grams or 3.45kg
So it is closer to 3kg because the total weight is under 3.5kg so that means you round down to 3kg. If it was 3.5kg you would round up to 4kg but their combined weight is not more than 3.45kg
Which graph represents this inequality? Y ≥ 4x-3
Answer:
It is the second graph B
Step-by-step explanation:
the first graph has the line graphed correctly except that it has a dashed line instead of a solid line because the equation is greater than and equal to the line should be solid not dashed
The inequality of the graph is the shaded area left side of the line. Then the correct option is B.
What is inequality?Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.
The inequality is given as,
y ≥ 4x – 3
The inequality of the graph is the shaded area left side of the line.

Answer:
65°
Step-by-step explanation:
∠1=115°
∠2=65°
∠3=65°
∠4=115°
∠5=115°
∠6=65°
∠7=115°
∠8=65°
We get this because Line m and l are parallel. Also ∠1+∠2=180° so if ∠1 is 115°, then ∠2 is 180°-115° or 65°.
