Answer:
49 in first box, 40 in second box. I took the test.
The equation of an ellipse with center (-9, 3), focus (-6, 3) and major axis length of 14 units is [tex]\frac{(x+9)^2}{49} + \frac{(y-3)^2}{40}= 1[/tex]
The standard form of the equation of an ellipse is:
[tex]\frac{(x-h)^2}{a^2} + \frac{(y-k)^2}{b^2}= 1[/tex]
The center of the ellipse, (h, h) = (-9, 3)
That is, h = -9, k = 3
The length of the major axis = 14 units
The length of the major axis = 2a
2a = 14
a = 14/2
a = 7
a² = 7²
a² = 49
The coordinates of the foci are [tex](h \pm c, k)[/tex]
One of the foci = (-6, 3)
h - c = -6
-9 - c = -6
c = -9 + 6
c = -3
[tex]c^2 = a^2 - b^2\\(-3)^2 = 7^2 - b^2\\9 = 49 - b^2\\b^2 = 49 - 9\\b^2 = 40[/tex]
Substitute a² = 49, b² = 40, h = -9, and k = 3 into the equation [tex]\frac{(x-h)^2}{a^2} + \frac{(y-k)^2}{b^2}= 1[/tex]
[tex]\frac{(x+9)^2}{49} + \frac{(y-3)^2}{40}= 1[/tex]
The equation of an ellipse with center (-9, 3), focus (-6, 3) and major axis length of 14 units is [tex]\frac{(x+9)^2}{49} + \frac{(y-3)^2}{40}= 1[/tex]

38% of the 1200 Robinson students are 7" graders. How many Robinson
students are 7 graders?
For percentages, we write the number before the % sign as a decimal out of 1. So our percentage would actually be 0.38
To find what percent of Robinson students are 7th graders, we simply multiply 0.38 by 1200 which gives us 456
The answer is 456

Count the number of places it takes to get one place past 3
There are 5 zeros in the given question. That gets you to just before the 3.
Add one more to get past the 3. That makes 5 zeros + 1 more place = 6
Since you are moving right, the 6 is minus. Your answer is 3 * 10^-6

Answer:
D. 6 1/12
Step-by-step explanation:
First add the like fractions.
3 2/3 + 2/3 = 3 4/3 (Don't worry about simplifying yet)
Now find the least common multiple for 3 4/3 and 1 3/4 so we can add them.
REMEMBER: You can only add and subtract fractions when they have the same denominator.3: 3, 6, 9, 12
4: 4, 8, 12
In this case 12 is the least common multiple.
3/4 x 3/3 = 9/12 9/12
4/3 x 4/4 = 16/12
Add those two fractions then add the whole numbers and put it in front.

Which of the following would have infinitely many solutions?
3x = 6 + 3x
2(x + 2) = 2x + 4 4x – 5 = 3 (x – 4)
-X + 6 = x + 6
9
Answer:
Below.
Step-by-step explanation:
2(x + 2) = 2x + 4
2x + 4 = 2x + 4
Both sides are identical so we can replace x with any value we like and the equation will balance, so there are infinitely many solutions.
Answer:
2(x+2)=2x+4

Z1 and z2 are complementary angels given m z1= 12°, find mZ2.
m2
Sum of two angles that are complementary = 90°
m∠1 + m∠2 = 90°
Given :
m∠1 = 12°
Then :-
[tex]12° + ∠2 = 90°[/tex]
[tex]∠2 = 90 - 12[/tex]
[tex]∠2 = 78°[/tex]
∴ m∠2 = 78°Find the height of a cylinder with a volume of 36piecm and a bad with a radius of 3cm
Step-by-step explanation:
V=pi×r^2×h
36pi =pi × (3)^2 × h
36pi ÷ pi×9 = h
4cm^2 = h

3. Write the formula for the area of a triangle, A = 1/2 bh, in terms of h. Find
the height of a triangle when A = 18 in.? and b = 9 in.
Show work to get the answer
Answer:
Area = 1/2 bh
Area = 18
Base = 9
height = ?
18 = 1/2 x 9 x h
cross multiply
18 x 2 = 1 x 9 x h
36 = 9h
divide both sides by 9
h = 4
(a) The formula for area of a triangle is expressed in terms of h as [tex]h = \frac{2A}{b}[/tex]
(b) The height, h of the triangle is calculated as 4 in

write an equation of a line that passes through the point (4,2) with a slope of 1/4
Answer:
Slope Intercept Form: y = [tex]\frac{1}{4}[/tex] x + 1
Point Slope Form: y - 2 = [tex]\frac{1}{4}[/tex] × (x - 4)
Standard Form: 1x - 4y = -4
Step-by-step explanation:
Answer:
[tex]y=\frac{1}{4} x+1[/tex]
Step-by-step explanation:
A linear equation needs two pieces of information: the slope of the line, and its y-intercept. Since we are already given the slope we can plug that into the standard equation format:
y=mx+c, where m=slope and c=y-intercept
y=1/4x+c
Now we just need to find the y-intercept.
To find it we are given a point: (4,2), which we can use to trace back to the y-intercept using the slope. The slope of the line of 1/4. This means that the point before it is located 4 units to the left on the x intercept, and 1 unit lower on the y-intercept. Conveniently, this gives us our y-intercept, as the x values 4-4=0. The y value is 1 (2-1) so our y-intercept is 1!
So now we have our equation:
y=1/4x+1

6+ 12x + 36 = -8.5x - 40 equations with variables
Answer:
x=-4
Step-by-step explanation:
First, you would simplify the like terms on both sides of the equation to get 42 + 12x = -8.5x - 40
Second, you would want to add and subtract terms to get the X's on one side, and the whole numbers on the other.
12x + 8.5x = -40-42
Third, simply the terms.
20.5x=-82
Fourth, divide both sides by 20.5 to get the x on its own, and then you will have your answer of x=4.

Kyle incorrectly says that the product of - ( - 6 ) # ( - 1 ) is 6 . 11. After a recycling awareness program, the number of tons of recyclable material taken to the landfill is reduced by 13 7/10 tons per month. Represent the total change in the tons of recyclable material taken to the landfill after 7 months resulting from the awareness program a. What is the correct product? 10 month. Represent the total change in the b. What was Kyle's likely error?
Answer:
Kindly check explanation
Step-by-step explanation:
Given that :
Kyle incorrectly says that the product of - ( - 6 ) ( - 1 ) is 6
-(-6)(-1) = 6 [incorrect]
Correction:
-(-6) (-1) :
- (-6) = 6
6 (-1) = - 6
Given that reduction in materials = 13 7/10 tons per month
Monthly reduction = 13 7/10 = 137/10 tons
After 7 months : (7 * 137/10) = 959/10 tons = 95.9 tons
Change in amount of material taken to the land fill:
Initial amount - amount after 7 months
If initial amount = x
Change in amonnt = (x - 95.9) tons
Subtract 5x ^ 2 + 2x - 11 from 3x ^ 2 + 8x - 7 . Express the result as a trinomial.
Answer:
2x2−6x−4
Step-by-step explanation:
Let's simplify step-by-step.
5x^2+2x−11−(3x^2+8x−7)
Distribute the Negative Sign:
=5x^2+2x−11+−1(3x^2+8x−7)
=5x^2+2x+−11+−1(3x^2)+−1(8x)+(−1)(−7)
=5x^2+2x+−11+−3x^2+−8x+7
Combine Like Terms:
=5x^2+2x+−11+−3x^2+−8x+7
=(5x^2+−3x^2)+(2x+−8x)+(−11+7)
=2x^2+−6x+−4
