Answer: [tex]6.2\ cm[/tex]
Step-by-step explanation:
Given
The volume of the sphere is [tex]V=996\ cm^3[/tex]
Volume of sphere is given by [tex]V=\dfrac{4}{3}\pi r^3[/tex]
Insert the values
[tex]\Rightarrow 996=\dfrac{4}{3}\times \dfrac{22}{7}r^3\\\\\Rightarrow r^3=\dfrac{996\times 21}{88}\\\\\Rightarrow r=6.2\ cm[/tex]
Thus, the radius of the sphere is [tex]6.2\ cm[/tex]
I have this math problem and it is: an equation in function from that reflects f(x)=3x over the line y=0.
Answer:
[tex]g(x) = -3x[/tex]
Step-by-step explanation:
Given
[tex]f(x) = 3x[/tex]
Required
Reflect over [tex]y = 0[/tex]
This means that we reflect over the x-axis
And the rule of reflection is:
[tex](x,y) \to (x,-y)[/tex]
Hence:
[tex]f(x) = 3x[/tex]
Will become:
[tex]g(x) = -f(x)[/tex]
So, we have:
[tex]g(x) = -3x[/tex]
PLEASE HELP! SEE PHOTO FOR QUESTION
Answer:
A
Step-by-step explanation:
Intercepts are basically points where if one of the coordinates is a number above 0, the other one HAS TO BE 0
Since there are three points where there are x-intercepts (since the y is 0), there will be three x-intercepts.
Since there is only one point where there are y-intercepts (since the x is 0), there will be only one y-intercept.
The intercepts don't give an exact answer so you would have to estimate where they are on the graph. For example, the y-intercept is between 20-30 and is leaning more towards 30, so you would think it's around 27-29 (And if you look at option A, you can see that it's (0,28))
You got the answer wrong because for one of the x-intercepts, you said that it was negative when it was actually positive. (I believe it was the (2.3,0) one.)
which method should be used for x? 2.5x=5.7

The straight line 3x + 4y = 24 cuts the y - axis at the point A and cuts the x - axis at the point B. What is the distance AB?
Step-by-step explanation:
the answer is in the above image
The distance between point A and point B is 10 units.
What is the distance between two points on a plane?The distance between two points on a coordinate plane (x, y) and (x, y) is
= √[(x₂ - x₁)² + (y₂ - y₁)²] units
The given straight line is 3x + 4y = 24.
This straight line will cut the x-axis at a point where y = 0.
Therefore, 3x + 4(0) = 24
⇒ 3x = 24
⇒ x = 8
Therefore, the coordinates of the point A is (8, 0).
Similarly, this straight line will cut the y-axis at a point where x = 0.
Therefore, 3(0) + 4y = 24
⇒ 4y = 24
⇒ y = 6
Therefore, the coordinates of the point B is (0, 6).
Therefore, the distance between point A and point B is
= √[(0 - 8)² + (6 - 0)²] units
= √(64 + 36) units
= √100 units
= 10 units (negative sign is avoided.)

Raul is flying a kite at the end of a string that is 200 feet long. Raul is holding the string 5 feet off the ground at the angle to the horizontal of 25. How high is the kite off the ground?
Answer:
Kite is 89.52 ft off the ground
Step-by-step explanation:
We are told that the string is 200 ft long.
That the string is 5 ft off the ground at an angle of 25° to the horizontal.
I have drawn a triangle to depict this illustration with x being the height of the kite from the end of the string.
Also, I have depicted the ground level which is 5 ft below the end of the string.
From the triangle, we can calculate the height of the kite above the end of the string using pythagoras theorem.
x/200 = sin 25
x = 200 sin 25
x = 200 × 0.4226
x = 84.52 ft
Now, the bottom of the kite is 5 ft off the ground as depicted in the attachment.
Thus, height of kite above the ground = 84.52 + 5 = 89.52 ft

Se tienen 25 billetes de 5 y de 20 lempiras con un monto de 350 lempiras cuantos billetes de 5 lempiras se tienen y de 20 lempiras
Answer:
El número de facturas
5 lempiras = 10 billetes
20 lempiras = 15 billetes
Step-by-step explanation:
Vamos a representar
El número de facturas de
5 lempiras = x
20 lempiras = y
Nuestro sistema de ecuaciones se da como:
x + y = 25 ..... Ecuación 1
x = 25 - y
5 × x + 20 × y = 350
5x + 20y = 350 .... Ecuación 2
Sustituiríamos x por 25 - y en la ecuación 2
5 (25 - años) + 20y = 350
125 - 5 años + 20 años = 350
125 + 15 años = 350
15 años = 350 - 125
15 años = 225
y = 225/15
y = 15
Resolviendo para x
x = 25 - y
x = 25 - 15
x = 10
Por lo tanto, el número de facturas
5 lempiras = 10 billetes
20 lempiras = 15 billetes

Write the equation in standard form for the circle x2 + 32 = -y² + 12x.
Step-by-step explanation:
Move
26
to the right side of the equation because it does not contain a variable.
3x2−12x−2y2+16y=26
Answer:
(x - 6)² + y² = 4
Step-by-step explanation:
x² + 32 = -y² + 12x
Rearrange
x² - 12x + y² = -32
Complete the square for x
(x - 6)² + y² = -32 + (-6)²
(x - 6)² + y² = -32 + 36
(x - 6)² + y² = 4
What is the axis of symmetry for the function f(x)=7−4x+x2?
x = –3
x = –2
x = 2
x = 3
Answer:
Answer:
x = 2
Step-by-step explanation:
The vertex form of the parabola is given by
Comparing this equation with vertex form of a parabola , where (h,k) is the vertex
h = 2
k = 3
Hence, vertex is (2,3)
Now, axis of symmetry of a parabola passes through the vertex and divide the parabola in two equal halves.
Hence, axis of symmetry of the parabola is given by
x = h
x = 2

Her efforts are finally paying off. On her first assessment she scored 58 points, then she scores 63 and 68 on her next two assessments. If her scores continued to increase at the same rate, on which assessments will she be scoring above 85? Select all that apply.
Answer:
7th
Step-by-step explanation:
63 - 58 = 5
68-63 = 5
She is adding 5 points each time
a1 = 58
d = 5
a2 = 63
a3 = 68
a4 = 58+5 = 73
a5 = 73+5 = 78
a6 = 78+5 = 83
a7 = 83+5 = 88
This is the first assessment greater then 85, so the 7th assessment
