Answer:
(3) 12
Step-by-step explanation:
Let x represent the length of leg XY. Then the length of YZ is x/2 and the area of the right triangle is ...
A = 1/2bh
A = 1/2(x)(x/2) = x²/4
36 = x²/4 . . . . . use the given value for area
144 = x² . . . . . . multiply by 4
√144 = 12 = x . . . . . take the square root
The length of leg XY is 12 cm.
one half plus one third
Answer:
0.83333333333
Step-by-step explanation:
One-half plus one-third equals 5/6 or 0.8333.
Given that:
Expression: 1/2 + 1/3
To add one-half (1/2) and one-third (1/3), to find a common denominator and then add the fractions together.
The least common denominator (LCD) of 2 and 3 is 6. To convert the fractions to have a common denominator of 6, multiply the numerator and denominator of 1/2 by 3, and the numerator and denominator of 1/3 by 2:
1/2 × 3/3 = 3/6
1/3 × 2/2 = 2/6
Now that the fractions have a common denominator of 6, add them:
3/6 + 2/6 = 5/6
3/6 + 2/6 = 0.8333
Therefore, one-half plus one-third equals 5/6 or 0.8333.

Use Newton's method to app a root of the equation 3x^7+2x^4+3=0
Let x1=1 be the initial approximation
Second approx. x2 is?
Third approx x3 is?
9514 1404 393
Answer:
x2 = .72413793x3 = .087249546Step-by-step explanation:
Modern graphing calculators have a derivative function available, so using a calculator to find the next value of x is pretty simple.
The Newton's Method iterator for finding the next approximation to the root (x') is ...
x' = x -f(x)/f'(x) . . . . . where f'(x) is the derivative of f(x).
The attachment shows the first 3 iterations (4 approximations). We observe that the starting point is pretty far from the root, and on the wrong side of some wiggles in the function, so convergence is pretty slow.
The desired approximations are shown above and in the table below.
__
Additional comment
To 12 significant figures, the only real root is −1.10305899649. When the calculator can interactively produce a next guess, you can type the next guess value into the iterator function even as it is showing you the next value. This lets you find the best-precision result as fast as you can type it.
For a calculator like a TI-84, the iterator function can make repeated use of "Ans" as an argument. It usually doesn't take more than 3 or 4 iterations to get a best-precision result, since the number of good decimal places is about doubled on each iteration. (Of course, you have to start with a better approximation than the one given in this problem.)
What is the answer to this
Answer:
x = 25
Step-by-step explanation:
3x-15 = 2x+10
x-15 = 10
x = 25
Answer:
x = 25 degree
Step-by-step explanation:
3x - 15 = 2x + 10 (their relation will be alternate interior angles if they [tex]l_{1}[/tex] and [tex]l_{2}[/tex] are parallel)
3x - 2x = 10 + 15
x = 25 degree

Step-by-step explanation:
a rope of length 18 m is used to form a sector of a circle of radius 3.5 m on a school field. What is the size of the angle of the sector?
Answer:
Perimeter of the sector = 2r + length of arc= 2(3.5)+11= 7+11=18 meters exactly the length of the rope.
Step-by-step explanation:
The perimeter of the sector is equivalent to the length of the rope which is 18 meters
Perimeter of the sector= 2 x radius + length of the arc
But length of arc= radius x central angle in radian
18= 2(3.5)+ 3.5(central angle in radians)
18=7+3.5 (central angle in radians)
18–7=3.5(central angle)
11=3.5(central angle)
central angle =11/3.5=3.14 radians or pi radians
Angle in degrees =pi radians x 360 degrees/2pi radians =pi radians x 180 degrees/pi radians = 180 degrees
Therefore the central angle = 180 degrees because pi radians is half of 2pi radians which is half of 360 degrees
Notes: This sector shape is a semicircle because the central angle is 180 degrees
Check: Length of Arc for semicircle =3.5(pi radians)=11 meters
Perimeter of the sector = 2r + length of arc= 2(3.5)+11= 7+11=18 meters exactly the length of the rope.

0,-2,-4,-6,-8,-10 nth term
Answer:
The nth term of this sequence is [tex]a_{n} = -2n + 2[/tex]
Step-by-step explanation:
In this sequence we keep adding -2 on to get the next term. This sequence is called an arithmetic sequence, a sequence that uses addition to keep increasing.
The formula for the nth term of an arithmetic sequence is
[tex]a_{n} = d[/tex] · [tex]n + a_{1} - d[/tex]
[tex]a_{1}[/tex] stands for the first term in the sequence, and [tex]d[/tex] stands for the difference between each number in the sequence.
[tex]a_{1} = 0[/tex] and [tex]d[/tex] = -2, so :
[tex]a_{n} = -2[/tex] · [tex]n + 0 - (-2)\\[/tex]
[tex]a_{n} = -2n + 2[/tex]
Therefore, to find the nth term in this sequence you would use the formula
[tex]a_{n} = -2n + 2[/tex]
What is the production matrix?
Answer:

Step-by-step explanation:
Here we want to compute the product of two matrices, one 2x2, and other 2x1.
[tex]\left[\begin{array}{ccc}0.3&0.3\\0.35&0.4\end{array}\right]*\left[\begin{array}{ccc}4\\6\end{array}\right][/tex]
Remember that in the product, we multiply the rows of the first one by the columns of the second one, then the product is just:
[tex]\left[\begin{array}{ccc}0.3&0.3\\0.35&0.4\end{array}\right]*\left[\begin{array}{ccc}4\\6\end{array}\right] = \left[\begin{array}{ccc}0.3*4 + 0.3*6\\0.35*4 + 0.4*6\end{array}\right] = \left[\begin{array}{ccc}3\\3.8\end{array}\right][/tex]

Find the surface area of
the prism.
Answer:
[tex]\text{D. }464\:\mathrm{ft^2}[/tex]
Step-by-step explanation:
The surface area of the prism consists of four rectangles and two trapezoids. The sum of the areas of these polygons will give the total surface area of the prism:
Rectangle 1 (top base): [tex]12\cdot 14=168[/tex]
Rectangle 2 (bottom base): [tex]6\cdot 14 = 84[/tex]
Trapezoids 1 and 2 (lateral): [tex]2\cdot 9 \cdot 4=72[/tex]
Rectangles 3 and 4 (lateral): [tex]2\cdot 14\cdot 5=140[/tex]
Thus the total surface area is equal to
[tex]168+84+72+140=\boxed{\text{D. }464\:\mathrm{ft^2}}[/tex]
In the accompanying diagram, ABC is isosceles, BC is extended to D. AB = AC. and M
Answer:
m∠ACD = 130
Step-by-step explanation:
If ABC is an isosceles, AB = AC and m∠A = 80°, then m∠B and m∠C is equal to 50°.
This is because angles in a triangle adds up to 180°.
180° - 80° = 100°/2 = 50°
∴ m∠ACD = 130°, this is because the interior opposite angles in a triangle is supplementary to the opposite exterior angle:
50° + 80° = 130°
Or
Angles on a straight line adds up to 180°.
180° - 50° = 130°

Answer:
see below
Step-by-step explanation: 6 5 17 43
Volume of a sphere = 121.5 π mm³ Find r
Vol Sphere = (4π r³) / 3 solve for r
Vol Sphere × 3 = (4π r³)
(Vol Sphere × 3) / 4π = r³
∛((Vol Sphere × 3) / 4π) = r
∛((121.5 π mm³× 3) / 4π) = r the pi terms cancel
∛((121.5 mm³× 3) / 4) = r
∛((364.5 mm³) / 4) = r
∛((91.125 mm³) ) = r
4.5 = r

The solution set to the absolute value is:
[tex]S = \{x \in \mathbb{R}| x \ge 0\}[/tex] or [tex]S = [0, +\infty)[/tex]
Negative real numbers are not included in the solution set, as for [tex]x < 0[/tex], [tex]|x| = - x[/tex].
Step-by-step explanation:
From Mathematics, we know that absolute values are defined by the following characteristics:
1) For [tex]x \ge 0[/tex], [tex]|x| = x[/tex]
2) For [tex]x < 0[/tex], [tex]|x| = - x[/tex]
Then, if [tex]|x| = x[/tex], then the solution set to the absolute value is:
[tex]S = \{x \in \mathbb{R}| x \ge 0\}[/tex] or [tex]S = [0, +\infty)[/tex]
Negative real numbers are not included in the solution set, as for [tex]x < 0[/tex], [tex]|x| = - x[/tex].
