the locus of all points that are the same distance from (3,-2) and (3,4) is one straight line. Draw this straight line
Answer:
No answer i can provide
Step-by-step explanation:
If you need to make a line on a graph, you need to plot at least 2 points. Luckily, the two points have been given.
Plot the points on your graph. for your first coordinate, go 3 over and down 2. for your second point, go over 3 and up by 4. for the line, draw it through your 2 points.
Hope this helps!
Answer:
line is y = 1
Step-by-step explanation:
the question is talking about loci, in this case 2 point
these 2 points are (3,-2) and (3,4)
draw a line to connect these to points and bisect the line.
to do this use a compass : put the compass more than half way and place it one the first point - draw an arc .
then draw another arc at the sencond point
were the 2 arcs meet draw a line - this straight line will be the answer.
y = 1

Step-by-step explanation:
Answer:
The hypotenuse is 17.
Step-by-step explanation:
a^2+b^2=c^2.
Let's plug in a and b.
15^2 + 8^2 = c^2
Simply.
225+64=c^2
Add.
289=c^2.
Square 289 and c^2 to cancel out the ^2.
17=c

3. In the expansion of (ax^2+ by)^8 the coefficients of last two terms are -5832 and 6561, respectively.
Find the values of: a and b
Answer:
a = -0.33
b = 3
Step-by-step explanation:
(ax²+ by)⁸
by the 8th level of Pascal Triangle, the coefficient of last 2 terms are
8 a*b⁷ = -5832 ... last 2nd term 8 ab⁷ x²y⁷
b⁸ = 6561 ... last term b⁸y⁸
b = 3
a = -5832/(8*3⁷) = -0.33

Step-by-step explanation:
10 − 3x = − 2 (x + 4)
=> 10 − 3x = -2x - 8
=> x = 18
Hoped this helped.
Answer:
x = 18
Step-by-step explanation:
10 - 3x= -2(x+4)
First, we solve inside the parentheses.
10 - 3x= -2x - 8
Like terms:
-3x + 2x= -10 - 8
-x/-1 = -18/-1
x = 18

Which equations represent circles that have a diameter of 12 units and a center that lies on the y-axis? Select two options.
x2 + (y – 3)2 = 36
x2 + (y – 5)2 = 6
(x – 4)² + y² = 36
(x + 6)² + y² = 144
x2 + (y + 8)2 = 36
Answer:
x2 + (y + 8)2 = 36
Step-by-step explanation:
:) took the test
The equations which represent circles that have a diameter of 12 units and a center that lies on the y-axis are x² + (y – 3)² = 36 and x² + (y + 8)² = 36.
What is the Standard form of a Circle?Standard form of a circle is given by the equation,
(x - h)² + (y - k)² = r²
where, (h, k) is the center of the circle and r is the radius of the circle.
Given that,
A circle has a diameter of 12 units.
So radius = 12 / 2 = 6 units
Center of the circle lies on the Y axis.
So the x coordinate of the center of the circle will be 0.
So, in (h, k), h = 0
So the equation will be of the form,
(x - 0)² + (y - k)² = 6²
x² + (y - k)² = 36
Hence the options are x² + (y – 3)² = 36 and x² + (y + 8)² = 36.

lf the volume of a sphere= 4.5π cm³ then the radius length is .....?
Answer:
Radius = 3.232 cm to the nearest thousandth.
Step-by-step explanation:
Volume of a sphere = 4/3πr^3, so:
45π = 4/3πr^3 π is common to both sides, so:
45 = 4/3 r^3
r^3 = 45 * 3/4
r^3 = 33.75
r = 3.232 cm.
