Find the angle of XYZ give your answer to 1 decimal place
Answer:
66.4°
Step-by-step explanation:
To find the angle XYZ, we are to use sine rule. For this, we have to first find ∠Z.
Given that: ∠X = 90° (right angle), XY = 6 cm, YZ = 15 cm. Hence:
[tex]\frac{sin(Z)}{XY}=\frac{sin(X)}{YZ}\\\\Substituting:\\\\\frac{sin(Z)}{6} =\frac{sin(90)}{15} \\\\sin(Z)=\frac{sin(90)*6}{15}\\\\sin(Z)=0.4\\\\Z=sin^{-1}(0.4)\\\\Z=23.6^o[/tex]
∠X + ∠Y + ∠Z = 180° (sum of angles in a triangle)
90 + ∠Y + 23.6 = 180
113.6 + ∠Y = 180
∠Y = 180 - 113.6
∠Y = 66.4°
∠Y = ∠XYZ = 66.4°

Answer:
A
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
So the formula for slope is y = mx + b
Here is what it looks like so far: y = -5x + 3
In that equation, -5 is m (slope)
and 3 is b (y-intercept)
So the answer is C

Line 4: y+3=1/8(x−1)
Lines 2 and 3 are perpendicular.
Lines 1 and 2 are perpendicular.
All four lines are perpendicular.
Lines 1 and 4 are perpendicular.
Answer:
All four lines are perpendicular
Step-by-step explanation:
Lines 1 and 2 are parallel
y+8x=−5;x+1/6y=−5
Lines 2 and 3 are parallel
x+1/6y=−5;y=−6x−7
Lines 1 and 4 are perpendicular they intercept
x+1/6y=−5;y+3=1/8(x−1)
All four lines are perpendicular
line 4 is perpendicular to all other lines

Answer: 50 percent solution because you will have to multiply the 10 percent by 5.
Step-by-step explanation:
Given that f ( x ) = 3 x − 2 and g ( x ) = 2 x , evaluate f ( g ( − 1 ) )
g(x) = 2x
9(-1) = -2
f(x) = 3x-2
f(g(-1)) = f(-2) = 3*(-2) - 2 = -8
Answer:
-8
Step-by-step explanation:
g(-1)= 2 * -1 = -2
So f(g(-1)) will be f(-2)
F(-2) = (3 * -2) - 2
= -6 - 2
= -8

solving [tex]100x^2-4=0[/tex] we get [tex]x=\frac{-1}{5}\:,\:x=\frac{1}{5}[/tex]
Step-by-step explanation:
We need to solve [tex]100x^2-4=0[/tex]
We know that [tex]10^2=100 \: and\: 2^2=4[/tex]
Replacing with the squares
[tex]100x^2-4=0\\(10x)^2-(2)^2=0[/tex]
We can use the formula: [tex]a^2-b^2=(a+b)(a-b)[/tex]
Applying formula
[tex](10x+2)(10x-2)=0\\10x+2=0\:,\:10x-2=0\\10x=-2\:,\:10x=2\\x=-2/10\:,\:x=2/10\\x=\frac{-1}{5}\:,\:x=\frac{1}{5}[/tex]
So, solving [tex]100x^2-4=0[/tex] we get [tex]x=\frac{-1}{5}\:,\:x=\frac{1}{5}[/tex]

I'm pretty sure it's true.
Step-by-step explanation:
If Z is the centroid of triangle TUV, TZ=60, XZ=28, and WZ=25, find each missing measure
The measure of length ZV, ZY, ZU, TY, and XV are 56, 30, 50, 60, and 78.
If Z is the centroid of triangle TUV, then the following are true:
ZV = 2ZX
Given that ZX = 28,
ZV = 2(28)
ZV = 56
Similarly, TZ = 2ZY
60 = 2ZY
ZY = 60/2
ZY = 30
Also, ZU = 2WZ
ZU = 2(25)
ZU = 50
TY = 2ZY
TY = 2(30)
TY = 60
XV = XZ + ZY
XV = 28 + 50
XV = 78
Therefore the measure of length ZV, ZY, ZU, TY, and XV are 56, 30, 50, 60, and 78.

What is the distance (length) of side LM?
Answer:
Distance, d = √((x2 - x1)² + (y2 - y1)²)
L(x1, y1) => L(-3, -1)
M(x2, y2) => M(2, 3)
Distance LM = √((2 - -3)² + (3 - -1)²)
= √((2 + 3)² + (3 + 1)²)
= √((5)² + (4)²)
= √(25 + 16)
= √ 41

A study about commuting time for workers in a certain city. The distribution is clustered on the left with most of the values less than about 40 minutes commute. There are a fairly large number of values that are much higher, even stretching out to 150 minutes. There is a 15% chance that a random worker has a commute time of greater than 45 minutes. If you were to sketch this distribution, what would it look like, how would you describe it, and how do you represent the 15% probability?
Answer:
Following are the solution to this question:
Step-by-step explanation:
Its laborer's journey through time was concentrated mostly on left as well as the amounts are mostly less than 4 min. There are quite a lot of significantly higher levels, even stretching to 150 min. A hypothetical worker is 15% likely to get a time difference longer than 45 min.
They learn from such data that perhaps the distribution of data takes a very long time. Thus the distribution will look like an's progressive. Its probability is positive. Therefore some severe finding beyond the regular standards is included. The mean of findings is also higher than the mean. Its problem would be that 15% of people are more likely to have been traveling more than 45 min in a specific worker. Subsequently, the 85th level of the data is 45 minutes, meaning whether 85% of observations are decreased or equivalent to 45 minutes or 15% more than 45 minutes.

The x-value is
The y-value is
The solution is
Step-by-step explanation:
The given equations are :
y = x + 3 .....(1)
y = 2x – 5 ......(2)
The table for equation (1) is :
x = 0, 1, 2, 8
y = 3, 4, 5, 11
The table for equation (2) is :
x = 0, 1 , 2, 8
y = -5, -3, -1, 11
From the graph we can see that,
The x-value is = 8
The y-value = 11
The solution is = (8,11).
The x-value is = 8, the y-value = 11 and the solution is = (8,11)
How to determine the equation solutions?The equations are given as:
y = x + 3
y = 2x - 5
Next, we plot the graph of the equations
From the graph of the equations, we have:
(x,y) = (8, 11)
Hence, the x-value is = 8 and the y-value = 11
So, the solution is = (8,11)
