Help and hurry pls!what is the perimeter of this figure?
Which is the equation of the line that passes through the points (-4, 8) and (1, 3)?
A. Y=x+4
B. Y=-x+12
C. Y=-x+4
D. Y=x+12
Answer:
Therefore the equation is y=-x+4 (correct optlon: C)
Step-by-step explanation:
In order to find the equation that passes through both points, we can use the slope-intercept form of the linear equation:
y=mx+b
Where m is the slope and b is the y-intercept.
Using the given points on this equation, we have:
(-4,8):
(-4,8):8=m*(-4)+b
(-4,8):8=m*(-4)+bb=8+4m
(-4,8):8=m*(-4)+bb=8+4m(1,3):
(-4,8):8=m*(-4)+bb=8+4m(1,3):3=m+b
(-4,8):8=m*(-4)+bb=8+4m(1,3):3=m+b3=m+8+4m
(-4,8):8=m*(-4)+bb=8+4m(1,3):3=m+b3=m+8+4m5m=3-8
(-4,8):8=m*(-4)+bb=8+4m(1,3):3=m+b3=m+8+4m5m=3-85m=-5
(-4,8):8=m*(-4)+bb=8+4m(1,3):3=m+b3=m+8+4m5m=3-85m=-5m=-1
(-4,8):8=m*(-4)+bb=8+4m(1,3):3=m+b3=m+8+4m5m=3-85m=-5m=-1b=8+4*(-1)=8-4=4
Therefore the equation is y=-x+4 (correct optlon: C)
∠1 and ∠2 are complementary angles.
∠1 = x°
∠2 = (3x + 30)°
Using this information, find the value of x.
Remember the formula for finding the missing degree in a right-angle (with two complementary angles)? Use ∠1 + ∠2 = 90°
x = 50
x = 75
x = 15
x = 150
[tex]\qquad \qquad\huge \underline{\boxed{\sf Answer}}[/tex]
In the given question, the two angles are complementary Angle pair, so the sum of their values will add up to 90°
that is ~
[tex]\qquad \sf \dashrightarrow \: (3x + 30) \degree + x \degree = 90 \degree[/tex]
[tex]\qquad \sf \dashrightarrow \: 3x + x + 30 \degree = 90 \degree[/tex]
[tex]\qquad \sf \dashrightarrow \: 4x = 90 \degree - 30 \degree[/tex]
[tex]\qquad \sf \dashrightarrow \: 4x = 60 \degree[/tex]
[tex]\qquad \sf \dashrightarrow \: x = 60 \div 4[/tex]
[tex]\qquad \sf \dashrightarrow \: x = 15 \degree[/tex]
Answer:
x = 15 (third option)
Step-by-step explanation:
Complementary angles sum up to 90°.
∠1 + ∠2 = 90°
x° + (3x + 30)° = 90°
x + 3x + 30 = 90
4x = 90 - 30
4x = 60
x = 60/4
x = 15

Find the indefinite integral using the substitution x = 3 sin(θ). (Use C for the constant of integration.) 1 (9 − x2)3/2 dx
It looks like the integral might be
[tex]\displaystyle \int (9 - x^2)^{3/2} \, dx[/tex]
or perhaps
[tex]\displaystyle \int \frac1{(9 - x^2)^{3/2}} \, dx[/tex]
Take note of the fact that both integrands are defined only over the interval -3 < x < 3.
For either integral, we substitute x = 3 sin(θ) and dx = 3 cos(θ) dθ.
Note that we want this substitution to be reversible, so we must restrict -π/2 ≤ θ ≤ π/2, an interval over which sine has an inverse. Then θ = arcsin(x/3).
The first case then reduces to
[tex]\displaystyle \int (9 - (3\sin(\theta))^2)^{3/2} (3 \cos(\theta) \, d\theta) = 3 \times 9^{3/2} \int (1 - \sin^2(\theta))^{3/2} \cos(\theta) \, d\theta \\\\ = 81 \int (\cos^2(\theta))^{3/2} \cos(\theta) \, d\theta \\\\ = 81 \int |\cos^3(\theta)| \cos(\theta) \, d\theta[/tex]
By definition of absolute value,
[tex]\displaystyle 81 \int |\cos^3(\theta)| \cos(\theta) \, d\theta = \begin{cases}\displaystyle 81 \int \cos^4(\theta) \, d\theta & \text{if }\cos(\theta) \ge 0 \\ \displaystyle -81 \int \cos^4(\theta) \, d\theta & \text{if }\cos(\theta) < 0\end{cases}[/tex]
and these cases correspond to 0 ≤ θ < π/2 and π/2 < θ ≤ π, respectively. But we are assuming -π/2 ≤ θ ≤ π/2, so the negative case doesn't matter to us.
You can compute the remaining antiderivative by exploiting the half-angle identity for cosine,
[tex]\cos^2(\theta) = \dfrac{1 + \cos(2\theta)}2[/tex]
Then
[tex]\cos^4(\theta) = \left(\cos^2(\theta)\right)^2 = \dfrac{1 + 2\cos(2\theta) + \cos^2(2\theta)}4 = \dfrac{3 + 4\cos(2\theta) + \cos(4\theta)}8[/tex]
and so
[tex]\displaystyle \int \cos^4(\theta) \, d\theta = \dfrac{12\theta + 8\sin(2\theta) + \sin(4\theta)}{32} + C[/tex]
We can simplify this using the double angle identity for (co)sine,
sin(2θ) = 2 sin(θ) cos(θ)
cos(2θ) = 1 - 2 sin²(θ)
as well as the relations,
sin(arcsin(x/3)) = x/3
cos(arcsin(x/3)) = √(9 - x²)/3
which gives us
[tex]\displaystyle \int \cos^4(\theta) \, d\theta = \dfrac{12\theta + 16 \sin(\theta) \cos(\theta) + 4 \sin(\theta) \cos(\theta) (1 - 2\sin^2(\theta))}{32} + C[/tex]
Putting this in terms of x, we get
[tex]\displaystyle \int (9 - x^2)^{3/2} \, dx \\ = 81 \times \dfrac{12\arcsin\left(\frac x3\right) + 16 \times \frac x3 \times \frac{\sqrt{9-x^2}}3 + 4\times\frac x3\times\frac{\sqrt{9-x^2}}3 \left(1 - 2\left(\frac x3\right)^2\right)}{32} + C[/tex]
[tex]\displaystyle \int (9 - x^2)^{3/2} \, dx = 81 \times \dfrac{12\arcsin\left(\frac x3\right) + \frac{16x\sqrt{9-x^2}}9 + \frac{4x(9-2x^2)\sqrt{9-x^2}}{81}}{32} + C[/tex]
[tex]\boxed{\displaystyle \int (9 - x^2)^{3/2} \, dx = \dfrac{12\arcsin\left(\frac x3\right) + (180x-8x^3)\sqrt{9-x^2}}{32} + C}[/tex]
If you were asking about the other integral, the first few steps are similar and you end up with the far more trivial integral and antiderivative
[tex]\displaystyle \frac19 \int \frac{d\theta}{\cos^2(\theta)} = \frac19 \int \sec^2(\theta) \, d\theta = \frac19 \tan(\theta) + C[/tex]
Putting it back in terms of x, we get
[tex]\displaystyle \int \frac1{(9 - x^2)^{3/2}} \, dx = \frac19 \tan\left(\arcsin\left(\frac x3\right)\right) + C[/tex]
Recall that tan(θ) = sin(θ)/cos(θ), so
[tex]\displaystyle \int \frac1{(9 - x^2)^{3/2}} \, dx = \frac19 \times \frac{\frac x3}{\frac{\sqrt{9-x^2}}3} + C[/tex]
[tex]\boxed{\displaystyle \int \frac1{(9 - x^2)^{3/2}} \, dx = \frac{x}{9\sqrt{9-x^2}} + C}[/tex]

Use the drop-down menus below to state the sequence of transformations that maps Figure W onto Figure X in the animation below. Then use those transformations to determine: are the two figures congruent? Use the drop-down menus to explain why or why not.
Answer:
Dilate, Reflect
Not congruent, dilations are used
Step-by-step explanation:
Dilate the figure by a scale factor of 1/3
Reflecting the resulting shape will map the figure
Step 1: Dilate by 1/3
Step 2: Reflect over the y-axis
Since dilations are used, the figures are not the same, as it changes area and side lengths.

Every month, Helen budgets $110 for coffee from the coffee bar located in the lobby of her apartment building. If she stops by the bar every morning and her average order costs $3.88, how much money will she have left after 16 days?
answer:
$47.92
explanation:
$3.88 × 16=$62.08
$110-$62.08=$47.92
the 16 is the days
110is the budget
3.88 is the cost
hope that helps
The total money Helen have left after 16 days will be $47.92
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
Given that Helen budgets for coffee from the coffee bar located in the lobby of her apartment building was $110. And she stops by the bar every morning and her average order costs $3.88.
The budget = 110 dollars
The average cost = 3.88 dollars
Then the average order costs for 16 days;
$3.88 × 16 = $62.08
Therefore, the money she have left after 16 days;
$110-$62.08=$47.92
Hence, The total money she have left after 16 days will be $47.92
