Answer:
a is 31 b is 38 x is 133. Y is 47
Step-by-step explanation:
A is 31 because the other side is 31. we know the sides are the same because of the markings. B is 38 because the other side is 38 we know that because of the markings which mean its the same. X is 133 Y should be 47 because ALL ANGLES IN A QUADRILATERAL IS EQUAL TO 360. 133+133=266 360-266 is 94. 94 is for both angles so we need to divide by 2 the answer for Y is 47
Find the ratio created when BA is partitioned by C
Write your ratio with a, : and do not include spaces.
Answer:
[tex]AC:CB = 2:3[/tex]
Step-by-step explanation:
Given
The attached

Find the ratio when partitioned by C
When BA is partitioned, the segments are: AC and CB
From the attachment:
[tex]AC = 2[/tex]
[tex]CB = 3[/tex]
So, the ratio is:

Solve for the missing information given that the two triangles in each question are similar
Answer:
Step-by-step explanation:
One of the sides in each part is a variable. For the small triangle, it is x. For the irregular quadulatural, it is y. X is the longest of the 3 sides of the triangle. Y is the longest side of the quadulatural. Does this answer your question?

Write the coordinates of the vertices after a reflection over the line y=3
Answer:
T'(-1, 4), U'(8, 4) and V'(-1, 10)
Step-by-step explanation:
If we reflect the vertices of the given triangle VTU across a line y = 3,
Rule to followed for the image points,
Line of reflection will work as a mirror.
And distance of image points and original points will be same from the line of reflection.
Therefore, Coordinates of the vertices of the image triangle will be,
T'(-1, 4), U'(8, 4) and V'(-1, 10)

What is the value of x in the figure below if JW=17 and YW=3x+1
(will mark brainlest)
Answer:
[tex]x = 11[/tex]
Step-by-step explanation:
Given
The attached parallelogram
[tex]JW = 17[/tex]
[tex]YW = 3x + 1[/tex]
Required
Find x
JW is the midpoint of YW. So:
[tex]YW = 2 * JW[/tex]
This gives
[tex]3x + 1 = 2 * 17[/tex]
[tex]3x + 1 = 34[/tex]
Subtract 1 from both sides
[tex]3x = 33[/tex]
Divide through by 2
[tex]x = 11[/tex]

Find the central angle using a ratio in regards to angle and circumference.
The radius is 27 units, so use the following equation to calculate circumference:
C = 2rπ
Therefore:
C = 2(27)π = 54π
Since we have the total circumference, we can write the following proportion:
[tex]\frac{x}{360} = \frac{18\pi}{54\pi}[/tex]
Cross multiply:
54πx = 6480π
Divide both sides by 54π to isolate for x:
x = 120°
The equation relating the number of customized cell phones produced and the profit per cell phone is p=-2.50n2+21n, where n is in 100000s. Plot the resulting graph. Be sure to label and number the axes appropriately and indicate the maximum value of p
Answer:
Please find attached the graph of the profit function created wit Microsoft Excel
The maximum profit, p[tex]_{max}[/tex] = 4,410,000
Step-by-step explanation:
The given equation is presented as follows;
The profit, p = -2.5·n² + 21·n
The value of n is given in 100,000 s
Differentiating the profit function and equating the result to zero to find the values for the maximum profit, we have;
d(-2.5·n² + 21·n)/dn = -5·n + 21 = 0
n = 21/5 = 4.2
The maximum profit, f(4.2) = -2.5 × 4.2² + 21 × 4.2 = 44.1
The maximum profit, f(4.2) = 44.1 × 100,000 = 4,410,000

What is the total amount of interest using simple interest given the following: Principal: $20,000 Interest rate: 12% Time: 10 Months
Answer:
Amount = $22000
Step-by-step explanation:
Amount = Principal + Interest
Get the interest
Interest = PRT/100
Interest = 20,000*12*10/12*100
Interest = 200 * 10
Interest = $2000
Amount = $20,000 + $2000
Amount = $22000
The first second and fourth terms of a proportion are 6, 18 and 25 respectively. Find
its third term.
Answer:
The third term is 25/3
Explanation:
According to the given proportion,
→ First term : second term : : third term : fourth
→ 6 : 18 : : third term : 25
→ 6/18 = third term/25
→ 6*25/18 = third term [multiplying both sides by 25]
→ 1*25/3 = third term
→ 25/3 = third term.

z^11
Step-by-step explanation:
The applicable rule of exponents is ...

Additional comment
It might help you to think of an exponent as indicating repeated multiplication. It tells you how many times the factor is repeated. In this case, it means ...
[tex]z^5\cdot z^6=(z\cdot z\cdot z\cdot z\cdot z)\cdot(z\cdot z\cdot z\cdot z\cdot z\cdot z)\\=z\cdot z\cdot z\cdot z\cdot z\cdot z\cdot z\cdot z\cdot z\cdot z\cdot z = z^{11}[/tex]
