The focus of a parabola is (-10, -7), and its directrix is x = 16. Fill in the missing terms and signs in the parabola's equation in standard form.
Answer:
The equation of the parabola in standard form is x = y²/52 + 7·y/26 - [tex]2\frac{3}{52}[/tex]
Step-by-step explanation:
The standard form of a parabola is a·y² + b·y + c
The focus of the parabola = (-10, -7), the directrix is x = 16, we have;
The coordinate of the focus is given as_F(h + p, k)
Where;
p = 1/(4·a)
The equation of the directrix is x = h - p
Therefore, given that the coordinates of the focus = (-10, -7), we have;
k = -7
Given that the equation of the directrix is x = 16, we have;
h - p = 16...(1)
h + p = -10...(2)
Adding equation (1) and (2), gives;
2·h = 6
h = 6/2 = 3
h = 3
From equation (1), p = h - 16 = 3 - 16 = -13
The general equation of the parabola is (y - k)² = 4·p·(x - h), therefore, substituting the values gives;
(y - (-7))² = 4 × (-13) × (x - 3)
(y + 7)² = -52·(x - 3)
y² + 14·y + 49 = -52·x + 156
x = (y² + 14·y + 49 - 156)/(-52) = (y² + 14·y + 49 - 156)/(-52) = y²/52 + 7·y/26 -107/52
Answer:
(y+7)^2= -52(x-3)

Carrie’s allowance was $
24 dollars.
1/4 + 1/3 = 3/12 + 4/12 = 7/12

7/12 a = 14
a = 14 x 12/7
a = 24 dollars
Find the equation of the linear function represented by the table below in slope- intercept form. х: -2, 2, 6, 10 y: -5, 7, 19, 31
Answer:
y = 3x + 1
Step-by-step explanation:
Slope-intercept form is y = mx + b.
To find the slope (m), you use the equation (y1-y2)/(x1-x2). Plug in your points (-2, -5) and (2, 7) to get (-5 - 7)/(-2 - 2). Simplify the formula to get a slope of 3. This is your variable m.
To get the entire equation, finding b in the process, you use the formula y - y1 = m(x - x1). Replace m with 3. Using the point (-2, -5), replace it with (x1, y1) respectively to get y + 5 = 3(x + 2). Distribute to get y + 5 = 3x + 6. Isolate the y to get your final answer: y = 3x + 1.

What is the value of this function evaluated at f(-3): f(x) = 2x2+ 5x - 9? F -6 G -42 H 42 J 12
Answer:
f(-3) = -6
Step-by-step explanation:
f(x) = 2x^2+ 5x - 9
We are to find f(-3)
f(-3) = 2(-3)^2+ 5(-3) - 9
f(-3) = 2(9)-15 - 9
f(-3) = 18 -15 -9
f(-3) = 18-24
f(-3) = -6

b/c the rule for x-axis is (x,y) --> (x, -y)
One of the points is (1, 1) ==> (1, -1)
4.) The rule for y-axis is (x, y) --> (-x, y)
A(-5, 3) --> A'(5, 3)
B(2, 6) --> B'(-2, 6)
C(-1, -7) --> C'(1, -7)
PAGE 2
5.) The rule for x-axis is (x,y) --> (x, -y)
A(-5, 3) ---> A'(-5, -3)
B(2, 6) ---> B'(2, -6)
C(-1, -7) ---> C'(-1, 7)
6.) The rule for 90 degrees clockwise is (x, y) --> (y, -x)
B(3, 4) ---> B'(4, -3)
PAGE 3
1.) On the transitions right is positive and left is negative
So 2 units to the right = +2
And 9 units down = - 9
So (x, y) --> (x + 2, y - 9)
2.) A is wrong b/c that translation is (x, y) ---> (x + 3, y -3)
B is wrong b/c the translation is (x, y) ---> (x + 3, y + 3)
C is wrong b/c the translation is (x, y) ---> (x - 3, y + 3)
D is correct b/c the translation is (x, y) --->(x -3 , y -3)
A(6, 6) --> A'(3, 3) B(7, 4) --> B'(4, 1) C(4, 4) --> C'(1, 1)
PAGE 4
7.) The rule for 90 degrees rotation counterclockwise is (x, y) --> (-y, x)
The correct graph would show A(-3, 3) ----> (-3, -3)
The only graph that shows this is Graph C
8.) The rule for 180 degrees rotation is (x, y) ----> (-x, -y)
The correct graph would show A(-3, 3) ----> A'(3, -3)
Graph B is the only one that ALL the angles follow this rule
PAGE 5
9.) It is Dilation with the center at the origin and a scale factor of 2.
B/c --> A(3, 3) ---> A'(6, 6) B(2, 0) ---> B'(4, 0) C(5, 2) ---> C'(10, 4)
(3*2= 6, 3*2=6) (2*2= 4, 0*2= 0) (5*2= 10, 2*2= 4)
10.) It is Dilation with the center at the origin and a scale factor of 1/3
B/c ---> A(-3, 6) --> A'(-1, 2) B(12, 3) ----> B'(4, 1) C(-6, -6) ---> C'(-2, -2)
(-3*1/3= -1, 6*1/3= 2) (12*1/3= 4, 3*1/3= 1) (-6*1/3= -2, -6*1/3= -2)

Step-by-step explanation:
Step 1: Define Equation
3x - 6 = 9
Step 2: Solve for x
Add 6 to both sides: 3x = 15Divide 3 on both sides: x = 5Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: 3(5) - 6 = 9Multiply: 15 - 6 = 9Subtract: 9 = 9Here we see that 9 does indeed equal 9.

On the first day after the new moon, 2% of the Moon's surface is illuminated. On the second day, 6% is illuminated. Based on this information, predict the day on which the Moon's surface is 50% illuminated and 100% illuminated.
illuminated.
PLEASE HELPPPPPPP!!!!!!!!!!!
Answer:
Day 13= 50%
Day 26=100%
Step-by-step explanation:
Answers vary. Sample response: A simple approach is to attempt a linear model starting at Day 1. If the illumination is increased by 4% every day, then after 11 more days (after Day 2) it reaches 50%. In 13 more days, illumination reaches 100%. This gives a prediction of Day 13 for 50% and Day 26 for 100%.
The days where it is illuminated is Day 13= 50% and Day 26=100%
Linear model:Here A simple approach should be considered for linear model that begins at Day 1. In the case when the illumination is increased by 4% every day, so after 11 more days (after Day 2) it reaches 50%. In 13 more days, illumination reaches 100%.
Therefore, we can conclude that The days where it is illuminated is Day 13= 50% and Day 26=100%
