Answer:
28.6 ft
Step-by-step explanation:
Given an hemisphere of volume [tex]49037 ft^3[/tex]
Volume of a Hemisphere of radius r [tex]=\frac{2}{3}\pi r^3[/tex]
Therefore:
[tex]\frac{2}{3}\pi r^3=49037 \\r^3=49037 X \frac{3}{2 \pi}\\r=\sqrt[3]{49037 X \frac{3}{2 \pi}} \\r=28.6\: foot[/tex]
The radius of the hemisphere is 28.6 foot to the nearest tenth.

Use Vieta's Theorem to solve the problems. The difference of the two solutions of x2+19x+c=0 is 15. Find c.
Answer:
c = 34
Step-by-step explanation:
x = [-19 +/- sqrt(19² - 4(1)(c)]/2
x = [-19 +/- sqrt(361 - 4c)]/2
The difference of the roots would be:
sqrt(361 - 4c) = 15
361 - 4c = 15²
361 - 225 = 4c
4c = 136
c = 34

The standard deviation of sample data is "[tex]s = \sqrt{\frac{(x_1 -\bar{x})^2+ (x_2-\bar{x})^2 + ..... + (x_n -\bar{x})^2}{ n- 1}}[/tex]"
The standard deviation of the sample data:Random variables, samples, statistical populations, information sets, or probabilistic distributions are equal to the square root of its variance.
It's much less resilient in reality than the average absolute deviation, but it makes algebraic expressions easier.
A sampling divided by the size of the data set is less than one, n - 1. To get the standard deviation, take the square root of the variance. The standard deviation is obtained by taking the square root of the standard deviation.
Therefore, the standard deviation of sample data is "[tex]s = \sqrt{\frac{(x_1 -\bar{x})^2+ (x_2-\bar{x})^2 + ..... + (x_n -\bar{x})^2}{ n- 1}}[/tex]"

A triangle undergoes a sequence of transformations. First, the triangle is dilated by a scale factor of 1/3 about the origin. Then the triangle is reflected over the x-axis. Finally, the triangle is translated left 3 units and up 2 units. How does the image triangle compare to the pre-image triangle?
The image triangle compare to the pre-image triangle will be similar due to dilation.
Step-by-step explanation:
As given in the question ,the sequence of transformation undergone by a triangle are :-
First, the triangle is dilated by a scale factor of 1/3 about the origin.Secondly, the triangle is reflected over the x-axis the triangle is translated left 3 units and up 2 units.
Due to the process of dilation, the two triangles will be similar. Another important factor is that the scale factor is less than one and is a reduction, thus, the image will be smaller than the pre-image but the triangle will be similar
The transformations mentioned in the above statement altered the position and scale of the triangle, but the angle measures of both the triangle remains the same.
Thus we can say that
The image triangle compare to the pre-image triangle will be similar due to dilation.
Answer:
Sample Response: Because there was a dilation, the two triangles will be similar. The scale factor was less than one, so the image will be smaller than the pre-image.

Solving equations and distributive property
Answer:
The answer is 10
Step-by-step explanation: You multiply the 2 times twenty to get 40 then multiply the 2 times 2x to get 4x then subtract fourty from both sides and you will get fourty and then divide so 40 divided by 4x equals 10.
Answer:
x=10
Step-by-step explanation:
2x20=40 and 2x2x=4x move the 40 to the other side so 80-40=40 so 4x=40 4x10=40 so 10 should be correct.

Step-by-step explanation:
so first you have to look at the problem and see what type of relationship the angles have. so if you draw it out yourself, it makes it a little easier and you can see that the two angles are corresponding angles, which means theyre both congruent or, equal.
after you find that out you can set up an equation so,
7x + 40 = 3x + 112
you do the math...
4x + 40 = 112

Use a trigonometric ratio to find the value of x. Round your answer to the nearest
tenth.
Answer:
x = 7.6
Step-by-step explanation:
Label the values you have on the triangle: The X is opposite, the 33 is your theta (ø) and 14 is your hypotenuse
Plug these values into the equation sin(ø)=o/h making the equation sin(33)=x/14.
Take the 14 and multiply it on the opposite side, making the equation look like this: 14xsin(33)=x
Then plug this into the TI-83/84 calculator and make sure it is degree mode (mode, degree)
Then just round to the nearest tenth. :)

Step-by-step explanation:
1. The values in the x-axis increase by 2 hence a=3-2=1 and c=7+2=9. For the y-values, they increase by 1.
2. The equation of the line can be written in the slope form of y=mx+c where m is the gradient of the line and c is the y-intercept
Taking points on the line ; (-2,-2) and (2,0) the gradient m is ;

If the terminal ray of β lies in the fourth quadrant and sin (β) = -√3/3 determine cos(β) in simplest form.
Answer:
[tex]cos(\beta)=\frac{\sqrt{6}}{3}}[/tex]
Step-by-step explanation:
we know that
If the terminal ray of β lies in the fourth quadrant
then
sin (β) is negative and cos (β) is positive
Remember the trigonometric identity
[tex]sin^2(\beta)+cos^2(\beta)=1[/tex]
we have
[tex]sin(\beta)=-\frac{\sqrt{3}}{3}[/tex]
substitute
[tex](-\frac{\sqrt{3}}{3})^2+cos^2(\beta)=1[/tex]
[tex]\frac{3}{9}+cos^2(\beta)=1[/tex]
[tex]cos^2(\beta)=1-\frac{3}{9}[/tex]
[tex]cos^2(\beta)=\frac{6}{9}[/tex]
apply root square both sides
[tex]cos(\beta)=\frac{\sqrt{6}}{3}}[/tex]

PLS HELP! THIS IS OVERDUE! ''What is the range of possible lengths for the third side of a triangle that has side lengths of 7 and 10?''
The length has to be greater than the absolute difference between the other two lengths, but less than the sum of them. In other words, if your unknown side length is a, and the other two are b and c, then its |b - c| < a < b + c
So, putting in your values, you have 10 - 7 < a < 10 + 7, which is 3 < a < 17
So, your range is from 3 to 17 (non inclusive).
The length has to be greater than the difference between the named two lengths, but less than the sum of them. So 3-17 is your answer.
a(1 ) = -2 a(n) = a(n - 1) - 5 Find the 4 ^ (th) term in the sequence .
Answer:
-17
Step-by-step explanation:
Each term in the sequence is 5 less than the one before, so the first 4 terms are ...
-2, -7, -12, -17
The 4th term of the sequence is -17.
__
The general term (an) of the sequence can be written as ...
an = a1 +d(n -1)
where a1 is the first term and d is the common difference. Here, those are ...
a1 = -2, d = -5
so the general term is ...
an = -2 -5(n -1)
We can use this to find the 4th term:
a4 = -2 -5(4 -3)
a4 = -17
Solve each equation. Be sure to check your solution.

In the circle below, UW is a diameter and UX is tangent at U. Suppose m UV=128
Answer:
Step-by-step explanation:
The value of the angle ∠VUW is 26° and ∠VUX will be 116°.
What is a circle?A circle is a geometrical figure which becomes by plotting a point around a fixed point by keeping a constant distance.
In our daily life, we always see circular objects for example our bike wheel.
The longest line which can be drawn inside the circle will be the diameter.
Area of circle = πr² and the perimeter of circle = 2πr where r is the radius of the circle.
Given the circle
Since ∠UOV is 128°
So,
∠UOW = 180 - ∠UOV
∠UOW = 180 - 128 = 52°
Now,
∠VUW = 1/2 ∠UOW
∠VUW = (1/2)52 = 26°
Now ∠VUX = ∠VUW + 90°
∠VUX = 26 + 90 = 116°
Hence "The value of the angle ∠VUW is 26° and ∠VUX will be 116°".
