In a unit circle, ø = 2pi radians What is the terminal point?
A. (0,1).
B. (0, -1)
C. (-1,0)
D. (1,0)
Answer:
The terminal point is (1, 0) ⇒ D
Step-by-step explanation:
In the unit circle, Ф is the angle between the terminal side and the positive part of the x-xis
The terminal point on the positive part of the x-axis is (1, 0),which means Ф = 0 or 2π radians and cosФ = 1, sinФ = 0The terminal point on the positive part of the y-axis is (0, 1),which means Ф = [tex]\frac{\pi }{2}[/tex] radians and cosФ = 0, sinФ = 1The terminal point on the negative part of the x-axis is (-1, 0),which means Ф = π radians and cosФ = -1, sinФ = 0The terminal point on the negative part of the y-axis is (0, -1),which means Ф = [tex]\frac{3\pi }{2}[/tex] radians and cosФ = 0, sinФ = -1In a unit circle
∵ Ф = 2π radians
→ By using the 1st rule above
∴ The terminal point is (1, 0)
Answer:
(1,0)

ΔHKJ and ΔLNP are similar triangle due to equal pair of corresponding angles .
What are Similar Triangles?Similar triangles are defined as two triangles with the same shape, equal pair of corresponding angles, and the same ratio of the corresponding sides.
Given,
m∠H = 30°
m∠J=50°
m∠P=50°
m∠N=100°
In triangle ΔHKJ
m∠H = 30°
m∠J=50°
m∠K= 180°- (m∠H+m∠J) = 180°-(30°+50°)
m∠K= 100°
In ΔHKJ and ΔLNP,
m∠J = m∠P= 50°
m∠K= m∠N= 100°
According to Angle-Angle (AA) rule, two triangles are said to be similar if two angles in one particular triangle are equal to two angles of another triangle.
Thus, ΔHKJ and ΔLNP are similar triangle due to equal pair of corresponding angles.
Hence, ΔHKJ ~ ΔLNP

Determine whether x^y•x^z=z^18
is sometimes, always, or never true. Explain.
9514 1404 393
Answer:
sometimes true
Step-by-step explanation:
The equation reduces to ...
x^y·x^z = z^18
x^(y+z) = z^18
This is not true in general, but is true for specific cases of x, y, and z. For example,
4^(7+2) = 2^18 . . . . (x, y, z) = (4, 7, 2)
4^(7+0) ≠ 0^18 . . . . (x, y, z) = (4, 7, 0)
The equation is sometimes true.

Determine any data values that are missing from the table, assuming that the data represent a linear function.
Answer:
c. 14
Step-by-step explanation:
Let the missing y value be y2.
If the data represent a linear function, then:
[tex] \frac{6 - 2}{2 - 1} = \frac{y_2 - 6}{4 - 2} [/tex]
[tex] \frac{4}{1} = \frac{y_2 - 6}{2} [/tex]
[tex] 4 = \frac{y_2 - 6}{2} [/tex]
Multiply both sides by 2
[tex] 4 \times 2 = \frac{y_2 - 6}{2} \times 2 [/tex]
[tex] 8 = y_2 - 6 [/tex]
Add 6 to both sides
[tex] 8 + 6 = y_2 - 6 + 6 [/tex]
[tex] 14 = y_2 [/tex]
The missing value is 14

Can someone help me with this math problem? “Solve the equation for y, if it’s not already solved for. If already solved for, type already solved.”
the equation: 5x+3y=15
Answer:
y=(-5/3x)+5
Step-by-step explanation:
so you want to isolate the variable of y.
5x+3y=15
5x+3y-5x=15-5x
3y=-5x+15
3y/3=(-5x+15)/3

The value of angle x.
Solution :
cos x = 1.7/2
Applying cos inverse both the sides, we get :
[tex]cos ^{-1} (cos\ x ) = cos^{-1} \dfrac{1.7}{2}\\\\x = cos^{-1} \dfrac{1.7}{2}[/tex]
Calculating the value of [tex]cos ^{-1} \dfrac{1.7}{2}[/tex] from calculator, we get :
x = 31.79°

Answer: 6[tex]\sqrt{2}[/tex]
Step-by-step explanation: Because the angles are the same, 45 and 45 the other leg of the triangle is also 6.
From there we can use the Pythagorean Theorum to solve for x
6^2+6^2 = 72
so x is [tex]\sqrt{72}[/tex]

Javine says, "To multiply by 1000, I just add three zeros." Kian says, "I times by 10, then times by 10 and times by 10 again." Do you agree with Javine and Kian's methods for multiplying by 1000? Explain your thinking.
Answer:
Kian's method is correct.
Step-by-step explanation:
Javine says, "To multiply by 1000, I just add three zeros." He is incorrect.
Kian says, "I times by 10, then times by 10 and times by 10 again. When he multiply 1 by 10, it becomes 10. Then if he again multiply by 10, it becomes 10×10 = 100. And at last when he multiply again 10, it becomes 100×10 = 1000. It means Kian's methods for multiplying by 1000 is correct.

Find the volume of a rectangular prism with the width of x-1, a length of x+1 and a height of 2x-3.
Answer:
The Volume is equal to 2x^3-3x^2+2x-3
Step-by-step explanation:
Formula for the volume of a rectangular prism is V=WHL
We know that:
W=x-1
L=x+1
H=2x-3
So, V= (x-1)(x-1)(2x-3)
Simplify
(x^2+1)(2x-3)
2x^3-3x^2+2x-3
