Which is the equation of a parabola with vertex (0,0) and directrix y= 4
a. Y^2 = -8x
b. Y^2 = -16x
c. X^2 = -8y
d X^2 = -16y
Answer:
D. [tex]x^{2} = -16\cdot y[/tex]
Step-by-step explanation:
The vertex form of the equation of the parabola centered in the origin, with axis of symmetry in the x-axis and directrix in the first and second quadrants is described by the following formula:
[tex]4\cdot p \cdot y = x^{2}[/tex], [tex]p < 0[/tex] (1)
Where:
[tex]y[/tex] - Dependent variable.
[tex]x[/tex] - Independent variable.
[tex]p[/tex] - Focus distance.
If we know that vertex is located at (0, 0) and the directrix pass through (4, 0), then the focus distance (distance of the vertex with respect to that point) is -4, and the equation of the parabola is [tex]x^{2} = -16\cdot y[/tex].
Hence, the right choice is D.

Find the magnitude of a vector with initial point A(3, 4, 10) and terminal point B(8, 4, –2).
A: 0
B: 13
C: 8
D:16
Answer:
B
Step-by-step explanation:
Use the distance formula in 3 dimensions
d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2+(z_{2}-z_{1})^2 }[/tex]
with (x₁, y₁, z₁ ) = (3, 4, 10) and (x₂, y₂, z₂ ) = (8, 4, - 2)
d = [tex]\sqrt{(8-3)^2+(4-4)^2+(-2-10)^2}[/tex]
= [tex]\sqrt{5^2+0^2+(-12)^2}[/tex]
= [tex]\sqrt{25+144}[/tex]
= [tex]\sqrt{169}[/tex]
= 13 → B

Elsa drove 864 miles in 12 hours.
At the same rate, how many miles would she drive in 8 hours?
Answer:
576 miles
Step-by-step explanation:
Answer:
else will drive 567 miles in 8h
Step-by-step explanation:
take 864÷ 12 to get how many hours she drives in one hour
you get 72
then you take 864÷2 to get how many miles she'll drive in 6h
you get 432
then you take 432 and add 144 or 72 + 72
and you get 567 miles in 8h

Find the value of x that makes the equation true

Answer:
[tex]x = - 3[/tex]
Step-by-step explanation:
Reason
[tex]3( - 2 + 1) + 5 = 3x - 4 - 5x \\ open \: the \: bracket \: at \: the \: lhs \\ - 6 + 3 + 5 = 3x - 4 - 5x \\ 2 = 3x - 4 - 5x \\ collect \: like \: terms \\ 2 + 4 = 3x - 5x \\ 6 = - 2x \\ 2x = - 6 \\ divide \: both \: sides \: by \: 2 \\ \frac{2x}{2} = \frac{ - 6}{2} \\ x = - 3[/tex]
in a regular polygon each interior angle is 140 greater than each exterior angle calculate the number of sides of each polygon .
Answer:
9
Step-by-step explanation:
Exterior sides = 180 - 140 = 40
number of sides = 360 / 40 = 9 sides
If the function y=1/x is translated to the left 2 units and up 6 units, what is the new horizontal asymptote
Answer:
y=6
Step-by-step explanation:
The horizontal asymptote for y = 1/x is the x-axis, y = 0.
Shifting the graph up 6 makes the asymptote move up, too, to y = 6.
See the attached image:
y = 1/x is purple
y = 1/(x + 2) + 6 is black
Point B has coordinates (3,1). The x-coordinate of point A is negative 1. The distance between point A and point B is 5 units. What are the possible coordinates of point A?
Answer:
Given in quesion:Point B (3,1) and point A is -1. Distance between A and B is 5 units.
Using distance formula for AB we obtain,
AB^2=(x2-x1)^2 + (y2-y1)^2
5^2=(3+1)^2 + (1-y)^2
25-16=(1-y)^2
9=(1-y)^2
1-y=3
y= -2
Therefore the possible co-ordinates of A are(-1,-2).This is your required answer.

5. At Ripona Middle School, there are 645 students,
in the student body. There is 258 girls. What
Percent of the students are boys?
Answer:
60% of students are boys
Step-by-step explanation:
Okay first subtract 645-258 to get the amount of boys at the school
645-258=387
Now the ratio of boys to girls is
387:258
387/645×100 to get percentage of boys
put that in your calculator and you will get 60%
so there is 60% of middle school boys and
258/645×100 to get the percentage of girls
put it in the calculator and you will get 40%
so 60% boys and 40% girls
60% + 40% = 100%
How do I do this I don’t understand it
Answer:
you graph it on the LINE and find the slope
Can you solve my question please, you will get brainlest, points, and stars!!!
IMPORTANT::: Write the #? Next to the answer.
Like for example there’s question #1,
Answer: #1 : .........e.t.c.
Then you write the answer.
Hope you get it!
Answer:
Below.
Step-by-step explanation:
One standard form of the equation of a straight line is
y = mx + c where m = the slope and c = the y-intercept.
Comparing this with y = 3x - 6 we see that:
The slope = 3 and the y-intercept is -6.
The error was in the y-intercept.
#2.
The error is in stating the intercepts
x - intercept is (8, 0) and y-intercept = (0, 2), (NOT (8, 2)).
#3.
The error is in stating the intercepts
x - intercept is (5, 0 and y-intercept = (0, 2).

= [tex]p^{\frac{3\times 2}{5\times 2}}\times \sqrt[10]{p^4}[/tex]
= [tex]p^{\frac{6}{10}}\times \sqrt[10]{p^4}[/tex]
= [tex]\sqrt[10]{p^{6}}\times\sqrt[10]{p^4}[/tex]
= [tex]\sqrt[10]{p^{10}}[/tex]
= p
Yes
12). [tex]p^{\frac{3}{5}}\times \sqrt[10]{p^4}=\sqrt[5]{p^3} \times \sqrt[10]{p^4}[/tex]
But, [tex]\sqrt[5]{p^3} \times \sqrt[10]{p^4}\neq \sqrt[3]{p^5}\times \sqrt[10]{p^4}[/tex]
No
13). Since, [tex]p^{\frac{3}{5}}\times \sqrt[10]{p^4}=p[/tex]
Simplify the given expression,
[tex]\sqrt[10]{p^{\frac{23}{5}}}[/tex]
[tex]\sqrt[10]{p^{\frac{23}{5}}} =p^{\frac{23}{50}}[/tex]
No.
14). [tex]p^{\frac{12}{50}}=p^{\frac{6}{25}}\neq p[/tex]
No.
15). [tex]p^{24}\neq p[/tex]
No.
