The equation x2 - 9 = 0 has
real solution(s).
DONE
Answer:
{-3, 3}
Step-by-step explanation:
x^2 - 9 = 0 can be written in factored form as (x -3)(x + 3) = 0. Letting each factor equal zero separately and solving for x, we get x: {-3, 3}

A piece of wire 16 feet long is strung from
the top of the side of a house to the
ground. The distance from the base of the
house to where the wire meets the ground
is 9 feet, as shown in the picture.
The figure is not diawn to scale)
How tall, in feel the house)
C 17
The height of the house is √175 feet if the piece of wire 16 feet long is strung from the top of the side of a house to the ground. option (C) is correct.
What is a right-angle triangle?It is a triangle in which one of the angles is 90 degrees and the other two are sharp angles. The sides of a right-angled triangle are known as the hypotenuse, perpendicular, and base.
As we can see the wire, wall and base making a right angle triangle;
So applying the Pythagoras theorem:
Supposing the length of the wall is x feet
16² = 9² + x²
x²= 175
x = √175 feet
Thus, the height of the house is √175 feet if the piece of wire 16 feet long is strung from the top of the side of a house to the ground. option (C) is correct.

10. Write the slope-intercept form of the equation of the
line parallel to the graph of 9x + 3y = 6 that passes
through (5,3).
Answer:
y = -3x + 18
Step-by-step explanation:
The slope intercept form of a line is expressed as y = mx+c
m is the slope
b is the intercept
Get the slope
Given the equation of a line 9x + 3y = 6
Rewrite
3y = -9x + 6
y = -9x/3 + 6/3
y = -3x + 2
Hence the slope of the line is -3
Get the y-intercept
Substitute m = -3 and (5,3) into y = mx+b
3 = -3(5) + b
3 = -15 + b
3 + 15 = b
18 = b
b = 18
Get the required equation
y = mx+b
y = -3x + 18
This gives the required equation

Step-by-step explanation:
We can see that 6 is 2 more than 3, and so the difference is -3^2, 9.
We can check this by seeing that -3^6 is -729 and -3^4 is -81.
We have
-729 / -81 = 9.

Bridget drew ΔYZ and Δ′ ′ ′ on a coordinate plane, as shown below.
Which statement about the relationship between ΔYZ and Δ′ ′ ′ is true?
(A)Δ′ ′ ′ is NOT a translation of ΔXYZ because the y-coordinate of Point is not the same as the y-coordinate of point ′.
(B)Δ′ ′ ′ is a translation of ΔXYZ because their corresponding sides are parallel.
(C)Δ′ ′ ′ is NOT a translation of ΔXYZ because not all points contained in Δ′ ′ ′ have negative x-coordinates.
(D)Δ′ ′ ′ is a translation of ΔXYZ because all points in Δ′ ′ ′ are the same distance and direction from the corresponding points in ΔXYZ.

Find the volume of a hemisphere when the diameter is 24 cm
Answer:
3619.6cm^3
Step-by-step explanation:
Given data
Daimeter= 24cm
Radius= 12cm
The formula for finding the volume of the hemisphere is given below
V = 2/3*π*r³
Substitute
V= 2/3*3.142*12^3
V= 2/3*3.142*1728
V= 10858.752/3
V=3619.6cm^3
Hence the volume is 3619.6cm^3

Find the volume of a cylinder with a diameter of 14mm and a height of 3.4mm Round to the nearest tenth.
Answer:
V≈5.23×10-7m³
Step-by-step explanation:
V=π(d
2)2h=π·(0.014
2)2·3.4×10-3≈5.23389×10-7m³
Answer: 523.1 mm^2
You first want to find the radius for the volume of cylinder formula. You first do 14 divided by 2 to get the radius. You should get 7. Then after you find the radius you then put it into the formula which is v=3.14 x radius^2 x height. The equation with all the numbers from the problem is 3.14 x 7^2 x 3.4. After you put the equation into your calculator you should get 523.1 mm^2.

Answer:
G = (y-x)/2
Step-by-step explanation:
Here, we want to find the value of the angle marked G
To do this, we are going to use one of the important circle angle-arc relationships
Thus, we have it that;
G = 1/2 (mFE - mJH)
G = 1/2 (y-x)
Which is simply
G = (y-x)/2

In the figure below, Z is the center of the circle. Suppose that OR=4, ST= 4, UZ= 6, and VZ=4x-6. Find the following.
Answer:
x = 3 units
SV = 2 units
Step-by-step explanation:
In[tex] \odot Z[/tex] QR and ST are chords such that:
QR = ST = 4
That is both the chords are equal in measure.
Equal chords are at equal distance from the center of the circle. Therefore,
VZ = UZ
4x - 6 = 6
4x = 6 + 6
4x = 12
x = 12/4
x = 3 units
Since, perpendicular dropped from the center of the circle bisects the chord.
[tex] \therefore SV = \frac{1}{2} ST[/tex]
[tex] \therefore SV = \frac{1}{2} \times 4[/tex]
[tex] \therefore SV = 2\: units[/tex]

Select the correct answer.
which equation matches the function shown in the graph?
A. Y = 1/2sin(x)
B. Y = sin(2x)
C. Y = sin(1/2x)
D. Y = sin(1/4x)
The equation for the graph is y = sin[(1/2)x] after applying the transformation x → (1/2)x option (C) is correct.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have:
A graph of a trigonometric function is shown in the graph:
From the graph of a function, we can see the sin function represented by the graph.
y = sin(x)
To find the equation for the graph we can apply the transformation to the above equation.
From the graph
x =2π
y = 0
x → (1/2)x
y = sin[(1/2)x]
Thus, the equation for the graph is y = sin[(1/2)x] after applying the transformation x → (1/2)x option (C) is correct.
