We are given the equation:
√(4x - 2) + 3 = 5
Subtracting by 3 on both sides
√(4x - 2) = 2
Squaring both sides
4x - 2 = 4
Adding 2 on both sides
4x = 6
x = 3/2
Step-by-step explanation:
Hey there!
Given;
[tex] \sqrt{4x - 2} + 3 = 5[/tex]
Shift "3" on right side.
[tex] \sqrt{4x - 2} = 5 - 3[/tex]
[tex] \sqrt{4x - 2} = 2[/tex]
Squaring on both sides.
[tex] {( \sqrt{4x - 2} )}^{2} = {2}^{2} [/tex]
Simplify it.
[tex]4x - 2 = 4[/tex]
[tex]4x = 4 + 2[/tex]
[tex]x = \frac{6}{4} [/tex]
[tex]x = \frac{3}{2} [/tex]
Therefore, X = 3/2.
Hope it helps...

Find the area of the shaded region in the figure below, if the diameter of the circle is 8 and the height of the rectangle is 10.
Use 3.14 for pi and round to the nearest hundredth.
Answers
Answer:
73.72 units²
Step-by-step explanation:
Area of the shaded region = Area if the rectangle - area of the semicircle
Area of the rectangle = length*width
Length = 10 units
Width = 8 units
Area of rectangle = 10*8 = 80 units²
Area of semicircle = ½(πr²)
radius (r) = 8/2 = 4 units
π = 3.14
Area of semicircle = ½(3.14*4) = 3.14*2 = 6.28 units²
Area of the shaded region = 80 - 6.28 = 73.72 units²
Answer: 54.88
Step-by-step explanation:
The shape shown is a circle that overlaps a rectangle. The shaded region is a rectangle with half a circle cut out. To find the area of the shaded region, we can find the area of the rectangle and the area of the overlapping semi-circle and subtract them. The rectangle has a height of 10. The width of the rectangle is the diameter of the circle, 8. First, find the area of the rectangle:
AAA=length×width=10⋅8=80
To find the area of the circle, we need to find the radius. The radius is one half the diameter, therefore r=4. Use the value of r to solve for the area:
AAA=πr2=3.14⋅(42)=50.24
Now we can subtract half the area of the circle from the area of the rectangle:
Area of rectangle−Area of half circle=Area shaded region
80−50.242
A=54.88
So the area of the shaded region is 54.88.

Given the set of test scores: 71, 75, 80, 81, 81, 84, 89, 93. If a score of 50 is added to the data set, which statement is true? Select all that apply. Choose all that apply:
The mean decreases.
The median decreases.
The standard deviation increases.
The range increases.
Answers
Answer:
The standard deviation increases, it's mean, medium and mode, if you put them in order and then go through and get your middle number it'll be 81.
If a score of 50 is added to the data set,
The standard deviation increases.
The range increases.
What is mean?"It is the average of all elements of the data set."
What is median?"It is the middle number in a sorted list of numbers."
Formula to calculate the standard deviation:[tex]SD=\sqrt{\frac{\sum{(x-M)^{2}} }{N} }[/tex]
where, SD is the population standard deviation
N : the size of the population
x : each value from the data
M : the mean of the data
Formula to calculate the range of the data:range = maximum value - minimum value
For given situation,
Consider the original set of test scores: 71, 75, 80, 81, 81, 84, 89, 93
N = 8
range R = 93 - 71
⇒ R = 22
Mean M = (71 + 75 + 80 + 81 + 81 + 84 + 89 + 93)/8
⇒ M = 654/8
⇒ M = 81.75
Now, we find the median K
First we sort given data set: 71, 75, 80, 81, 81, 84, 89, 93
The middle numbers are 81 and 81
So, the median is the average of 81, 81
So, K = 81
Now, we calculate the standard deviation.
[tex]SD=\sqrt{\frac{[(71-81.75)^{2}+(75-81.75)^{2}+...+(89-81.75)^{2}+(93-81.75)^{2}] }{8} }[/tex]
⇒ SD = 6.61
Consider, the set of test scores with 50 added to the data set.
N = 9
range R = 93 - 50
⇒ R = 43
Mean M = (71 + 75 + 80 + 81 + 50 + 81 + 84 + 89 + 93)/9
⇒ M = 704/9
⇒ M = 78.22
Now, we find the median K
First we sort given data set: 50, 71, 75, 80, 81, 81, 84, 89, 93
The middle number is 81.
So, the median is K = 81
Now, we calculate the standard deviation.
[tex]SD=\sqrt{\frac{[(71-81.75)^{2}+(75-81.75)^{2}+...+(50-81.75)^{2}+(93-81.75)^{2}] }{9} }[/tex]
⇒ SD = 11.76
So, we can observe that if a score of 50 is added to the data set, the correct statements are:
The standard deviation increases.
The range increases.

it is asking where on the graph is each point. it even gives you where it is located.
The coordinates of the triangle A"B"C" are A"(3, 2), B"(-1, 4) and C"(2, 0).
From the given graph, the coordinates of triangle ABC are A(1, -3), B(5, -1) and C(2, -5).
1) We know that, the reflection of point (x, y) across the y-axis is (-x, y).
Here,
A(1, -3)→A'(-1, -3)
B(5, -1)→B'(-5, -1)
C(2, -5)→C'(-2, -5)
2) The transformation with <4, 5> are
A'(-1, -3)→A"(-1+4, -3+5)
= A"(3, 2)
B'(-5, -1)→B"(-5+4, -1+5)
= B"(-1, 4)
C'(-2, -5)→C"(-2+4, -5+5)
= C"(2, 0)
Therefore, the coordinates of the triangle A"B"C" are A"(3, 2), B"(-1, 4) and C"(2, 0).

Now look at ( a ) and ( c ).
For ( a ) It's just f(x) = -2x but the graph that's shown here intercepts y-axis at (0,2). f(x) = -2x is just slope and intercepts y-axis at (0,0)
