Answer:
49
Step-by-step explanation:
first you find the difference between the first two numbers so we do 10-7=3, then plug in 3 for the next 2 numbers 10+3=13, so we know our rule is +3 so now we do 3*14=42 then we do 7+42=49

factor 2x^2-9x+9=0 and please show ur steps
Answer:
♡ hi there, madi here! ♡
hope your having a great day.
I did the math so here's your answer.
2x−3)(x−3)=0
If any individual factor on the left side of the equation is equal to 0, the entire expression will be equal to 0.
2x-3=0. x-3=0
Set the first factor equal to 0 and solve.
x=3/2
Set the next factor equal to 0 and solve.
x=3
Therefore, the final solution is all the values that make (2x-3) (x-3)=0 true. x=3/2,3♡

What is the answer to this geometry answer?
A researcher developing scanners to search for hidden weapons at airports has failed to conclude that a new scanner is significantly better than the current scanner. He made his decision based on a test using α=0.025.
a. Would he have made the same decision at α=0.20?
b. How about α=0.005? Explain.
Answer:
a. not sure
b. yes
Step-by-step explanation:
According to the given scenario, the following information is mentioned
[tex]\alpha[/tex] =0.025
In the case when the alpha is equivalent to 0.025 so the p test value would be more than the significance level i.e. 0.025 as the prescribed test is not important
So here
p>0.025
In the above case i.e. p>0.025 this does not mean that p>0.2 so we are not sure about this case whether he made teh same decision or not
Now in the another case, if the significant level is 0.005 so we are sure that p>0.005 as it is more than 0.025 so here also the test is not significant
So, here the same decision could be made

Find all angles between 0 and 2pi satisfying the condition cosx=-1/2
You can find the angles using the unit circle. You can also find the angle using algebra.
I want to show you the algebra way.
Since cos(x) = cos(2•pi - x), this leads to two equations.
The two equations are as follows:
cos (x) = -1/2...the given problem.
We also have cos (2•pi - x) = -1/2.
To isolate x for both trigonometric equations, use the inverse trig function idea.
Equation 1
arccos(cos x) = arccos (-1/2)
x = 2•pi/3
Equation 2
arccos(cos (2•pi - x)) = arccos (-1/2).
Note: 2•pi - x = 2•pi/3. We are not done with this equation. We must isolate x. In other words, like any other equation, solving for x is needed.
When we subtract 2•pi from both sides, the answer for x in the second equation is 4•pi/3.
As you know, 2•pi/3 and 4•pi/3 lie between 0 and 2•pi on the unit circle.
Answer: 2•pi/3, 4•pi/3

Angles A and B are complementary. Angle A measures 3x + 10
degrees and angle B measures 2x + 20 degrees. What is the value of
x?
Answer:
x = 12
Step-by-step explanation:
Lets set up the equation!
Complementary angles equal 90 degrees.
2x + 20 + 3x + 10 = 90
Now lets combine the like terms!
2x + 3x 20+ 10
5x +30 = 90
Now subtract 30 from both sides!
5x = 60
Divide each side by 5
x = 12

Coordinates of Z if Y is the midpoint of XZ, X(10,9) and Y(-4,8)
Answer:
[tex]Z(x,y) = (-18,7)[/tex]
Step-by-step explanation:
Given
[tex]X = (10,9)[/tex]
[tex]Y = (-4,8)[/tex]
Required
Determine the coordinates of Z
From the question, we understand that Y is the midpoint
And the midpoint is calculated as:
[tex](x,y) = (\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]
In this case:
[tex]Y(x,y) = (-4,8)[/tex]
[tex]X(x_1,y_1) = (10,9)[/tex]
[tex]Z = (x_2,y_2)[/tex]
So: This gives
[tex](x,y) = (\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]
[tex](-4,8) = (\frac{10+x_2}{2},\frac{9+y_2}{2})[/tex]
Multiply through by 2
[tex](-8,16) = (10 + x_2,9+y_2)[/tex]
By comparison:
[tex]-8 = 10 + x_2[/tex] and [tex]16 = 9 + y_2[/tex]
Solving for x2
[tex]-8 = 10 + x_2[/tex]
[tex]-8 - 10 = x_2[/tex]
[tex]-18 = x_2[/tex]
[tex]x_2 = -18[/tex]
Solving for y2
[tex]16 = 9 + y_2[/tex]
[tex]16 - 9 = y_2[/tex]
[tex]7 = y_2[/tex]
[tex]y_2 = 7[/tex]
Hence, the coordinates of Z is:
[tex]Z(x,y) = (-18,7)[/tex]
