Use OZ with VWXY
What is XY ?
A 30
B. 35
C. 40
D. 50
Answer:
Step-by-step explanation:
Chords having equal measures are equidistant from the center of the circle.
Since, VW = XY
Therefore, ZP = ZR = 15 units
A perpendicular line drawn from the center of a circle to the chord is the bisector of the chord.
VR = WR = 20 units
By applying Pythagoras theorem in ΔZRV,
ZV² = ZR² + VR²
ZV² = (15)² + (20)²
ZV = √(225 + 400)
ZV = √625
ZV = 25 units
Therefore, measure of radius ZV = 25 units.
VW = XY [Given]
Therefore, XY = 2(20)
= 40 units
Please help me! It isn’t hard im just not sure how to do it .
Answer:
a. Semester 1: 86.8, Semester 2: 87
b. Semester 1: 5.7, Semester 2: 6.3
c. Semester 1 because the standard deviation of the first semester was lower than of the second. This shows that his scores were closer to the mean and therefore he was more consistent.
Step-by-step explanation: Find the mean by taking the sum of the values for each semester and divide that sum by the number of values to find the average. Do this for both semesters. Now, find the absolute value of the difference between the mean and each value of the corresponding data set. Square each if those differences and sum them up. Now divide that sum by the number of data values and take the square root. This number is your standard deviation. You will use the standard deviations to make the comparison for part c. I hope this makes sense and helps!!!!

The area of a trapezoid is 70.55 square feet. The length of the bases are 11.4 feet and 5.6 feet. What is the height of the trapezoid?
Answer:
8.3 feet.
Step-by-step explanation:
Area = (h/2)(a + b) where h = height and a and b are the lengths of the 2 bases.
70.55 = (h/2)(11.4 + 5.6)
(h/2)(17) = 70.55
h/2 = 70.55/17
h = (2 * 70.55) / 17
h = 8.3 feet.

Find the area of the following surfaces using an explicit description of the surface.
The paraboloid z=2(x2+y2), for 0<=z<=8.
Answer:
68.47
Step-by-step explanation:
Given that:
The surface of the paraboloid [tex]z = 2(x^2 +y^2) \ for \ 0 \le z \le 8[/tex]
TO find the area of the given paraboloid, we need to first determine [tex]z_x \ and \ z_y[/tex].
This is because the surface area can be determined by using the formula:
[tex]\int \int _R \sqrt{z_x^2+z_y^2+ 1}\ dA[/tex]
Thus;
[tex]z_x = \dfrac{\partial }{\partial x}(2 ( x^2 +y^2) )[/tex]
[tex]z_x = 4x[/tex]
[tex]z_y = \dfrac{\partial }{\partial y }(2(x^2 +y^2))[/tex]
[tex]z_y = 4y[/tex]
Now;
[tex]\sqrt{z_x^2 + z_y^2 +1 } = \sqrt{(4x)^2 + (4y)^2+1 } \\ \\ \implies \sqrt{16x^2+16y^2+1}[/tex]
[tex]\implies \int \int \sqrt{16x^2 +16y^2+1}\ d x dy \\ \\ \implies \int \int \sqrt{16(x^2+y^2)+1 } \ dxdy[/tex]
Using the polar coordinate since the paraboloid shows the projection of a circle with [tex]x^2+y^2 =4[/tex]
[tex]\int \int \sqrt{16(x^2+y^2)+1 } \ dxdy = \int^{2 \pi}_{0} \ \int^{2}_{0} r \sqrt{16r^2+1} \ dr d\theta \\ \\ \implies \dfrac{1}{48} \Big ( ( 16r^2 +1 )^{\dfrac{3}{2}}\Big) ^2_0 \ \ \int ^{2 \pi}_{0} \ d \theta \\ \\ \implies \dfrac{2 \pi}{48} \Big ( (65^{\dfrac{3}{2}} -1 ) \Big) \\ \\ \implies \dfrac{2 \pi}{48}(523.046) \\ \\ \implies \mathbf{68. 47}[/tex]

please help me. f(x) = In(x)^6 find f'(x)
Answer:
f'(x) = 6/x
Step-by-step explanation:
1. Use logarithm rules to move the power to the front so ln(x)^6 becomes 6 ln(x).
2. Differentiate ln(x) which is always 1/x
3. multiply 1/x by the 6
6/x
cheryl wants to buy a bicycle that costs 160$. if she saves 12$ each week, what is the fewest number of weeks she must save in order to buy the bicycle?
please show the answer choices
Answer:
14 weeks.
Step-by-step explanation:
160/12= 13.8
13 weeks earns her $158
14 weeks earns her $160. So the fewest number of weeks she needs is 14.
What percent of 160 is 56?use the percent bare model
Answer:
35%
Step-by-step explanation:
This is simple, just use the formula: Number1 / Number 2 x 100 when you use it it will look like: 56/160x100 which 56/100 is 0.35 and 0.35x100 is 35%

Answer:
[tex]\sqrt[4]{768x^8y^5} = 4x^2y \sqrt[4]{3y}[/tex]
Step-by-step explanation:
Given
[tex]\sqrt[4]{768x^8y^5}[/tex]
Required
Simplify
We have:
[tex]\sqrt[4]{768x^8y^5}[/tex]
Expand 768
[tex]\sqrt[4]{768x^8y^5} = \sqrt[4]{256 * 3 * x^8y^5}[/tex]
Split
[tex]\sqrt[4]{768x^8y^5} = \sqrt[4]{256} * \sqrt[4]{3 * x^8y^5}[/tex]
[tex]\sqrt[4]{256} = 4[/tex]
So, we have:
[tex]\sqrt[4]{768x^8y^5} = 4* \sqrt[4]{3 * x^8y^5}[/tex]
Expand y^5
[tex]\sqrt[4]{768x^8y^5} = 4* \sqrt[4]{3 * x^8*y *y^4}[/tex]
Rewrite as:
[tex]\sqrt[4]{768x^8y^5} = 4* \sqrt[4]{3*y * x^8 *y^4}[/tex]
[tex]\sqrt[4]{768x^8y^5} = 4* \sqrt[4]{3y * x^8 *y^4}[/tex]
Split
[tex]\sqrt[4]{768x^8y^5} = 4* \sqrt[4]{3y} * \sqrt[4]{x^8 *y^4}[/tex]
Apply the following law of indices
[tex]\sqrt[a]{b} = b^\frac{1}{a}[/tex]
[tex]\sqrt[4]{768x^8y^5} = 4* \sqrt[4]{3y} * (x^8 *y^4)^\frac{1}{4}[/tex]
Expand
[tex]\sqrt[4]{768x^8y^5} = 4* \sqrt[4]{3y} * x^{8*\frac{1}{4}} *y^{4*\frac{1}{4}}[/tex]
[tex]\sqrt[4]{768x^8y^5} = 4* \sqrt[4]{3y} * x^2y[/tex]
Rewrite as:
[tex]\sqrt[4]{768x^8y^5} = 4* x^2y* \sqrt[4]{3y}[/tex]
[tex]\sqrt[4]{768x^8y^5} = 4x^2y \sqrt[4]{3y}[/tex]

Answer:
x = 88
Step-by-step explanation:
Becuase this is a quadrilateral, the opposite angles total 180 degrees. So, the opposite of x is 92. That would mean that x + 92 = 180. We subtract 92 from both non-variable sides to get the x by itself. 180 - 92 = 88. 92 - 92 = 0. this leaves us with X = 88

x= -1/2 is the answer to your question. Mark as brainliest!!!!
1) Solve for x.
(3.x - 2)°
(14x -19°
(9x+7)
Answer:
x = 12
Step-by-step explanation:
We will label the unknown interior angle of the triangle d.
14x - 19 + d = 180
14x + d = 199
d = 199 - 14x
199 - 14x + 3x + 9x + 7 - 2 = 180
199 - 2x +5 = 180
204 - 2x = 180
204 = 180 + 2x
2x = 24
x = 12
