Find The Measure Of The Missing Angles. Help Please

Answers

Answer 1

Answer:

< 1 = 92º

< 2 = 24º

< 3 = 35º

< 4 = 35º

< 5 = 81º

Step-by-step explanation:

< 1 = 180 - 88 = 92

< 3 = 64 corresponding angle due to parallel lines

< 2 = 180 - (92 + 64) = 24

< 4 = 180 - (64 - 81) = 35

< 5 = 180 - (64 + 35) = 81

Find the length of the leg x. Enter the exact value, not a decimal approximation.

Answers

Answer:
x = 2√13.

Step-by-step explanation:

Using the Pythagoras theorem:
14^2 = x^2 + 12^2
x^2 = 14^2 - 12^2
x^2 = (14 + 12)(14 - 12) = 52
x = √52
x = √4*√13
x = 2√13.

3. Is XY Tangent to circle Z?
Y
12 X
(20
Z
18

Answers

Answer:

XY is a tangent

Step-by-step explanation:

Given

[tex]XY = 12[/tex]

[tex]WY = 20[/tex]

[tex]WZ = 8[/tex]

Required

Is XY a tangent?

XY is a tangent if:

[tex]WY^2 = XY^2 + WX^2[/tex]

Because XY should make a right angle at point X with the circle

Where

[tex]WX = 2 * WZ[/tex]

So, we have:

[tex]WY^2 = XY^2 + WX^2[/tex]

[tex]WY^2 = XY^2 + (2*WZ)^2[/tex]

[tex]WY^2 = XY^2 + (2WZ)^2[/tex]

[tex]WY^2 = XY^2 + 4WZ^2[/tex]

This gives:

[tex]20^2 = 12^2 + 4*8^2[/tex]

[tex]400 = 144 + 256[/tex]

[tex]400 = 400[/tex]

Yes, XY is a tangent

Select the correct answer. Graph the given function and choose the key features that apply to its graph. y = x2 − 2x − 4

Answers

Answer:

Step-by-step explanation:

y = x^2 - 2x - 4

Convert to vertex form:

y = (x - 1)^2 - 1 - 4

y = (x - 1)^2 - 5

From this we conclude that there is a minimum vertex at (1, -5). It is a minimum because the coefficient of x^2 is positive.

It looks like a letter U  and its symmetrical about the line x = 1.

You can plot 3 more points at say, where x = -2  ( and y = (-2)^2 - 2(-2) - 4)

and x = 4 ( y = 4^2 - 2(4) - 4 ) . Also where x = 0 and y = -4.

then draw the graph through these 3 points and the vertex.

If x = 7 units, y = 2 units, and h = 9 units, find the area of the trapezoid shown above using decomposition.
A.
81 square units
B.
99 square units
C.
63 square units
D.
72 square units

Answers

Answer:

A) 81 sq units

Step-by-step explanation:

Area of a trapezoid = one-half of height multiplied by the sum of the bases (the bases are the parallel sides)

the problem gives us all the values we need:

height = 9

smaller base is 'x' which is 7

larger bases is 2y+x which is 2(2)+7 = 11

A = 1/2·(9)(7+11)

= 1/2·9·18

= 9·9 which is 81 sq units

The times that a cashier spends processing individual customers' orders are independent random variables with mean 3.5 minutes and standard deviation 3 minutes. Find the number of customers n such that the probability that the orders of all n customers can be processed in less than 2 hours, is approximately 0.1. (Round your answer to the nearest integer.)

Answers

Answer:

26 customers

Step-by-step explanation:

First:  determine the z score from standard normal probability table with an indicative area of 0.1

Z-score from probability table  = - 1.28

mean   = 3.5 minutes

std  = 3 minutes

next determine the Z-score based on the information given in the question

Z = ( std -  mean )  / processing time

  = ( 3 - 3.5 ) / 2 = -0.25

Finally determine the number of customers

N = [tex](\frac{-1.28}{-0.25} )^2[/tex]  = 1.6384 / 0.0625 = 26.21 ≈ 26 customers
