Which inequality best represents the Domain of the part show ?
a) y_>4.5
b) x_>4.5
c) y_> -2
d) x_>-2
Answers
Answer: D) [tex]x \ge -2[/tex]
==================================================
Explanation:
The domain is the set of all allowed x inputs.
The furthest to the left the curve goes is x = -2. So this is the smallest x value allowed as an input.
The largest input has no restriction since it grows forever toward the right (due to the arrow).
So we say that x can be -2 or larger meaning [tex]x \ge -2[/tex] is the domain.
-----------------
Extra info:
In interval notation, the domain would be [tex][-2, \infty)[/tex] to indicate the interval from -2 to positive infinity. The square bracket says "include the endpoint". The curved parenthesis says "exclude the endpoint". We can never reach infinity, so we cannot possibly include it as an endpoint, so we always use parenthesis for either infinity.

7. In name the bisected angles 1 and 2. If is 4x 3y, can be determined in terms of x and y? If so, state in terms of x+ y expression and explain your reasoning.
Answers
Answer:since there is no diagram i will answer to the best of my ability.
Step-by-step explanation:
If an angle is bisected then it is divided into 2 equal angles which i think they are naming 4x and 3y. In this case, 4x=3y. Solving for x, we get x= (3y)/4. Solving for y we get y= (4x)/3. Now if we substitute (4x)/3 for y in the equation x= (3y)/4 then x= (3(4x)/3)/4 = 4x/4=× so then we can say x÷y = measure of original angle that was bisected. Or znother way it can be said is x+y = 2x or x+ y =2y.

The initial values of the two functions are different and the rates of change of the two functions are the same

In order for output values to always be different, the two linear functions must describe parallel lines. That means the rates of change are the same, but the initial values are different.

What is the equation of a sine function with an amplitude of 2 and a period of 4
Answers
Answer: C
Step-by-step explanation:
For this problem, we need to know the standard form of a sine function and the meaning of each part.
Standard form: [tex]y=asin[b(x-h)]+k[/tex]
a=amplitude
b=period
h=phase shift
k=vertical replacement/shifting
Now that we know the standard form and the components, we know that we can forget about k and plug in 0 for h. This would leave us with [tex]y=asin[b(x)][/tex]. We know that the amplitude is 2, therefore, a=2. To find the period, you divide 2π by the given period. [tex]\frac{2\pi }{b} =\frac{2\pi }{4\pi } =\frac{2}{4} =\frac{1}{2}[/tex], therefore, b=1/2.
[tex]y=asin[b(x)][/tex] [plug in a=2]
[tex]y=2sin[b(x)][/tex] [plug in b=1/2]
[tex]y=2sin(\frac{1}{2}x)[/tex]
Therefore, C is the correct answer.

Use cylindrical coordinates to evaluate the triple integral ∭ where E is the solid bounded by the circular paraboloid z = 9 - 16(x^2 + y^2) and the xy -plane.

Answer:
[tex]\mathbf{\iiint_E E \sqrt{x^2+y^2} \ dV =\dfrac{81 \ \pi}{80}}[/tex]
Step-by-step explanation:
The Cylindrical coordinates are:
x = rcosθ, y = rsinθ and z = z
From the question, on the xy-plane;
[tex]9 -16 (x^2 + y^2) = 0 \\ \\ 16 (x^2 + y^2) = 9 \\ \\ x^2+y^2 = \dfrac{9}{16}[/tex]
[tex]x^2+y^2 = (\dfrac{3}{4})^2[/tex]
where:
0 ≤ r ≤ [tex]\dfrac{3}{4}[/tex] and 0 ≤ θ ≤ 2π
∴
[tex]\iiint_E E \sqrt{x^2+y^2} \ dV = \int^{2 \pi}_{0} \int ^{\dfrac{3}{4}}_{0} \int ^{9-16r^2}_{0} \ r \times rdzdrd \theta[/tex]

[tex]\iiint_E E \sqrt{x^2+y^2} \ dV = \int^{2 \pi}_{0} ( \dfrac{9r^3}{3}-\dfrac{16r^5}{5}})|^{\dfrac{3}{4}}_{0} \ drd \theta[/tex]

[tex]\iiint_E E \sqrt{x^2+y^2} \ dV = \int^{2 \pi}_{0} ( 3(\dfrac{3}{4})^3}-\dfrac{16(\dfrac{3}{4})^5}{5}}) d \theta[/tex]

If k(x)=5x-6, which expression is equivalent to (k+k)(4)
Answers
Answer: (k+k)(4)=28
Step-by-step explanation:
(k+k) (4) means the same as adding k(4) and k(4). Since we are given k(x), we can use it to solve. There are two ways to solve. One is to find k(4), and then add them. Another way is to do (k+k)(x), then plug in x=4. I will show both methods.
Method 1
k(4)=5(4)-6 [multiply]
k(4)=20-6 [subtract]
k(4)=14
(k+k)(4)=14+14 [add k(4) and k(4)]
(k+k)(4)=28
--------------------------------------------------------------------------------------------------------
Method 2
(k+k)(x)=5x-6+5x-6 [combine like terms]
(k+k)(x)=10x-12
(k+k)(4)=10(4)-12 [plug in x=4, multiply]
(k+k)(4)=40-12 [subtract]
(k+k)(4)=28
--------------------------------------------------------------------------------------------------------
Now, we know that (k+k)(4)=28. We confirmed this with both methods.

HELP WILL GIVE BRAINLIEST!!Aditi has $50.00 in her wallet. She buys a shirt for $12.00 and also wants to buy some bracelets that are on sale for $0.60 each. The inequality below relates x, the number of bracelets she can buy, with her shirt purchase and the money in her wallet.
12 + 0.60 x less-than-or-equal-to 50
What is the greatest number of bracelets she could buy?
Answers
Answer:
The greatest number of bracelets she can buy is 63.
Step-by-step explanation:
12 + 0.60x ≤ 50
Since we already have the inequality, we have to start picking random numbers(until there are no more solutions):1.) 12 + 0.60(63) ≤ 50
12 + 37.8 ≤ 50
49.8 ≤ 50
Since 49.8 ≤ 50 is always true, there are infinitely many solutions.
Now we know that she can buy 63 bracelets, we have to figure out if she can buy more:2.) 12 + 0.60(64) ≤ 50
12 + 38.4 ≤ 50
50.4 ≤ 50
Since 50.4 ≤ 50 is false, there is no solution.

Step-by-step explanation:
Write out the whole function using given information

Domain/y = 0.1x + 5
Substitute the possible values for x into the domain equation and solve
f(x) = 10: 0.1(10) + 5 = 1 + 5 = 6
f(x) = 50: 0.1(50) + 5 = 5 + 5 = 10
f(x) = 120: 0.1(120) + 5 = 12 + 5 = 17
