The paraboloid z = 5 − x − x2 − 2y2 intersects the plane x = 1 in a parabola. Find parametric equations in terms of t for the tangent line to this par
Complete question is;
The paraboloid z = 5 − x − x² − 2y² intersects the plane x = 1 in a parabola. Find parametric equations for the tangent line to this parabola at the point (1, 2, -4).
Answer:
x = 1
y = (2 + t)
z = (-4 - 8t)
Step-by-step explanation:
We are given the paraboloid z = 5 − x − x² − 2y²
That it intersects the plane x = 1 and tangent to the point (1, 2, -4).
Thus, the position of the tangent is;
r_o = (1, 2, -4).
Direction vector is; v = (x, y, z)
Let's put 1 for x into the paraboloid.
z = 5 − 1 − 1² − 2y²
z = 3 - 2y²
Now, let's use vectors to find the parametric equation, where;
x = 1
y = t
z = 3 - 2t²
Thus, the Directional vector is now;
v = (1, t, 3 - 2t²)
Derivative of this directional vector is;. v' = (0, 1, -4t)
Putting 2 for t gives;
v' = (0, 1, -4(2))
v' = (0, 1, -8)
Multiplying this derivative by T gjves;
tv' = (0, t, -8t)
The final direction vector will be;
r = r_o + tv'
r = (1, 2, -4) + (0, t, -8t)
r = (1, (2 + t), (-4 - 8t))
Thus our parametric equation is;
x = 1
y = (2 + t)
z = (-4 - 8t)
is there enough information to prove that the triangles are congruent?
If yes provide the correct triangle congruence postulate or theorem and a congruent statement
if no justify your answer
Answer:
Step-by-step explanation:
From the figure attached,
In the given right triangles ΔADB and ΔCDB,
Statements Reasons
1). ∠BAD ≅ ∠BCD 1). Given
2). BD ≅ BD 2). Reflexive property
3). ΔADB ≅ ΔCDB 3). By LA theorem of congruence of right triangles
Therefore, there is sufficient information to prove the ΔADB and ΔCDB congruent.
Leg-angle theorem (L-A) will be used to prove the right triangles congruent.
Answer:
Yes, there is (ASA)
Step-by-step explanation:
Here, we have a side common to the two triangles. That makes S
Also, we can see an angle on both triangles, that makes A
Lastly, there is a right angle on both triangle
That makes another A
So we have the ASA to prove the congruence of the two triangles

Add and Subtract Rational Expressions with a Common Denominator
In the following exercises, perform the indicated operations.
Answer:
[tex]\displaystyle \frac{4q^2-q+3}{q^2+6q+5}-\frac{3q^2-q-6}{q^2+6q+5}=\frac{q^2+9}{q^2+6q+5}[/tex]
Step-by-step explanation:
Simplifying Rational Expressions
If two or more rational expressions have the same denominator, the add and subtract operations are done only with the numerator. The final denominator will be the common of both.
The expression is:
[tex]\displaystyle \frac{4q^2-q+3}{q^2+6q+5}-\frac{3q^2-q-6}{q^2+6q+5}[/tex]
Operating on the numerators:
[tex]\displaystyle \frac{4q^2-q+3}{q^2+6q+5}-\frac{3q^2-q-6}{q^2+6q+5}=\frac{4q^2-q+3-(3q^2-q-6)}{q^2+6q+5}[/tex]
Removing parentheses:
[tex]\displaystyle \frac{4q^2-q+3}{q^2+6q+5}-\frac{3q^2-q-6}{q^2+6q+5}=\frac{4q^2-q+3-3q^2+q+6}{q^2+6q+5}[/tex]
Simplifying:
[tex]\boxed{\displaystyle \frac{4q^2-q+3}{q^2+6q+5}-\frac{3q^2-q-6}{q^2+6q+5}=\frac{q^2+9}{q^2+6q+5}}[/tex]
The expression cannot be further simplified.

Step-by-step explanation: The fashion express magazine having 4,880 subscribers and losing 300 times something lines up with that in the expression. And the new trends magazine having 3,140 and gaining 280 times something lines up with the expression. The expression is also suppose to be equal and the word problem is asking for when the subscriber count would be equal. Solving the expression using the word problem would have you end up with m = 3, so in 3 months they will have equal subscribers (aka both will have 3,980 subscribers)

Question 1 (1 point)
A mail carrier divides 4,830 envelopes into boxes. Each box can hold a maximum of 50 envelopes.
What is the minimum number of boxes the mail carrier must use?
Answer:
97 boxes
Explanation:
4,830÷50= 96.6
You then have to round 96.6 up and you get 97.
To check your answer:
97×50= 4,850
Even though having 97 boxes leaves more room for envelopes, having 96 boxes will leave all the boxes full with remaining envelopes. 96 boxes isn't enough for 4,830 envelopes.

Select the expression that is equivalent to 48 + 12.
A.
6(8 + 6)
B.
12(4 + 1)
C.
4(44 + 3)
D.
8(6 + 4)
Answer:
B.
Step-by-step explanation:
First in order to solve this problem we need to simplify the answer choices.
A. 6×8 + 6×6 = 48+ 36
B. 12×4 + 12×1=48+12
C. 4×44 + 4×3=176+12
D. 8×6 + 8×4 = 48+32
As you can see there is one expression that is equivalent to 48+12. Answer choice B is correct.
The expression that is equivalent to 48 + 12 is 12(4 + 1), Option B is correct.
What is Expression?An expression is combination of variables, numbers and operators.
To find the expression that is equivalent to 48 + 12, we need to simplify each of the given expressions and find the one that is equal to 60.
Because the value of 48+12 is 60
A. 6(8 + 6) = 6(14) = 84
B. 12(4 + 1) = 12(5) = 60
C. 4(44 + 3) = 4(47) = 188
D. 8(6 + 4) = 8(10) = 80
Out of the given expressions, only expression B simplifies to 60, which is equivalent to 48 + 12.
Therefore, the expression that is equivalent to 48 + 12 is 12(4 + 1), Option B is correct.

Answer:
C
Step-by-step explanation:
Monthly salary is $1,750 plus commission for every car he sells.
If he sells 1 car, then his monthly income is $2,250
This means his commission for every car sold is 2250 - 1750 = $500
Thus M = 500n + 1,750
To confirm lets substitute 5 as n.
M = (500 x 5) + 1750
M = 2500 + 1750
M = $4,250
This matches the answer found in the table.
