What is the measure of XZ?
A. 36°
B. 144°
C. 72°
D. 18°
Answer:
C.72
Step-by-step explanation:
angle XYZ is an inscribed angle and arc XZ is the arc it intercepts
If you didn't know the measure of an inscribed angle is equal to half the measure of its arc it intercepts or an intercepted arc equals twice the measure of its inscribed angle
Hence, angle XYZ * 2= arc XZ
If Angle XYZ = 36
then 36 * 2 = arc XZ
36 * 2 = 72
hence the answer is C
The measure of arc is 72 degree, the correct option is C.
What is an arc?An arc is formed by two radii and their intercepted part on the circumference.
According to the theorem of arc and subtended angles, the central angle subtended by the arc is double the angle subtended by it on the circumference.
The angle subtended by arc XZ on the circumference is 36 degree.
The angle subtended by the arc at the center is = 2 * 36 = 72 degree.
The arc subtended by the arc at the center of the circle is the measure of the arc.

The length of a rectangle flower bed is 5ft longer than its width. A sidewalk with a width of 3ft surrounds the bed. If the total area of the bed and sidewalk is 546ft^2, what are the dimensions of the flower bed ?
Answer:
[tex]W=15ft[/tex]
[tex]L=20ft[/tex]
Step-by-step explanation:
From the question we are told that:
Length of Bed [tex]L=5+W[/tex]
Width of sidewalk [tex]W_s=3ft[/tex]
Area of the bed and sidewalk [tex]A_t= 546ft^2[/tex]
Generally the equation for Area of the bed and sidewalk[tex]A_t[/tex] is mathematically given by
[tex]Area=L*B[/tex]
[tex]A_t=((3+3)+L)*((3+3)+W)[/tex]
Therefore
[tex]546=((3+3)+(5+W))*((3+3)+W)[/tex]
[tex]0=((6+(5+W))*((6)+W)-546[/tex]
[tex](11+W)*(6+W)-546=0[/tex]
[tex]W^2+17B-480=0[/tex]
Solving the Quadratic Equation
[tex]W=15ft[/tex] (Using only positive root)
Generally the Length L is mathematically given by
[tex]L=5+15[/tex]
[tex]L=20ft[/tex]

Point P is at (3,-3) it undergoes the transformation (x - 2, y + 3). Where is P' at?
Answer:
The coordinates of P' are [tex]P'(x,y) = (1, 0)[/tex].
Step-by-step explanation:
The coordinates of the point P' is determined by the following expression:
[tex]P'(x, y) = P(x,y) + T(x,y)[/tex] (1)
Where:
[tex]P(x,y)[/tex] - Original point.
[tex]P'(x,y)[/tex] - Translated point.
[tex]T(x,y)[/tex] - Translation vector.
If we know that [tex]P(x,y) = (3, -3)[/tex] and [tex]T(x,y) = (-2, 3)[/tex], then the coordinates of point P':
[tex]P'(x,y) = (3, -3) + (-2, 3)[/tex]
[tex]P'(x,y) = (1, 0)[/tex]
The coordinates of P' are [tex]P'(x,y) = (1, 0)[/tex].

Hilary measured the depth of the snow in her front yard for 7 days. An equation for Hilary's data is y = − 0.5 x + 8 . Let x represent the number of days, and y represent the depth of the snow in inches.
Answer:
4.5 inches
Step-by-step explanation:
Given:
y = -0.5x + 8
Where,
x = the number of days
y = the depth of the snow in inches
Find y when x = 7
y = -0.5x + 8
= -0.5(7) + 8
= -3.5 + 8
= 4.5
y = 4.5 inches
The depth of the snow in Hillary's front yard for 7 days is 4.5 inches

sin^-1(sin 17°)
Answer:
uhm 0 degrees
Step-by-step explanation:
The value of the inverse trigonometric expression sin⁻¹(sin 17°) will be 17°.
What is inverse trigonometry?Simply put, inverse trigonometric operations are the opposites of the fundamental trigonometric parameters sine, cosine, secant, cosecant, tangent, and cotangent.
The connection between the lengths and angles of a triangular shape is the subject of trigonometry.
The inverse trigonometric expression is given below.
⇒ sin⁻¹(sin 17°)
We know that the value of sin⁻¹(sin θ) is θ.
Then the value of the inverse trigonometric expression will be
⇒ sin⁻¹(sin 17°)
⇒ 17°
Thus, the value of the inverse trigonometric expression sin⁻¹(sin 17°) will be 17°.

Is it linear , quadratic, exponential
Answer:
Exponential
Step-by-step explanation:
So lets look at the table.
When x = 1, y = 3
When x = 2, y = 9.
Hmmm, this doenst seem like x+number=y. It doesnt seem like a quadratic, where the values go up, then down, then up again. Or vise versa.
So this rules out linear and quadratic, for the x doesnt change by a constant, or change the direction of y.
This leaves exponential or none of the above.
When x = 3, y = 27
When x = 4, y = 81
This seems like a exponent, since:
3 to the first power is 3
3 to the second power is 9
3 to the third power is 27
and 3 to the fourth power is 81
Answer:
exponential function

Find the percentage of him drawing a blue marble.
4/10 = 0.4
He has a 40% chance of picking blue.
Find 40% of 30.
12
He would draw a blue marble around 12 times.
Answer:
C
Explanation:
So in the bag, there are 10 marbles, and 4 of them are blue, so if he drew from the bag 10 times, we can assume the fraction:
4/10
Next, we see that the denominator, or the number times Cade is drawing from the bag is 30, which makes us multiply most sides of the fraction by 3:
12/30
So I would say 12/30, but again, he wouldn't draw a blue exactly 4 times, and it may be more or less, so either 8/12....
Hope this helps!
