On the map of an amusement park on a coordinate grid, the skating rink is at (−1.5, −1).Coordinate grid shown from negative 3 to positive 3 on x-axis and negative 3 to positive 3 on y-axis. There are increments of 1 over 2 for each grid line on each of the two axes. Only the whole numbers are labeled on either side of the axis.
Which of these shows how to plot the point to mark the skating rink?
From the origin, move 1.5 units to the left along the x-axis and 1 unit vertically down, and place the point.
From the origin, move 1 unit to the left along the x-axis and 1.5 units vertically down, and place the point.
From the origin, move 1 unit to the right along the x-axis and 1.5 units vertically down, and place the point.
From the origin, move 1.5 units to the right along the x-axis and 1 unit vertically down, and place the point.
Answers
Answer:
The correct option is 1.
Step-by-step explanation:
It is given that the skating rink is at (−1.5, −1).
Here, x-coordinate is -1.5 and y-coordinate is -1.
In a point P(a,b),
If a>0, then the point P is a units right from the origin and if a<0, then the point P is a units left from the origin.
If b>0, then the point P is b units up from the origin and if b<0, then the point P is b units down from the origin.
It the given point (-1.5, -1), a=-1.5 and b=-1 both are negative.
From the origin, move 1.5 units to the left along the x-axis and 1 unit vertically down, and place the point.
Therefore the correct option is 1.
Moving 1.5 units to the left (or -1.5 units to the right).
Moving 1 unit down (or -1 unit up).
Therefore you get the result of (-1.5, 1) as is the location of the rink.

Answers
P=$400
i=7.5%
A=$8500
The formula used for this problem is:
A = P(1+i)^t
Manipulating the equation to arrive at t, we have:
t = ln(A/P) / ln(1+i)
Plugging in values:
t = ln($8500/$400) / ln(1+0.075)
t = 42.26 years
inscribed angle = 1/2 · (intercepted arc) and
intercepted arc = central angle.
Be sure to use important vocabulary like “inscribed angle,” “central angle”, and “intercepted arc”.
Answers
Answer:
Angle of the intercepted arc is equal to the angle at the centre (central angle) but B is not the centre hence XBY is not 144°.
Angle at the circumference (inscribed angle) is half of the central angle, but XBY is not the central angle, so it's not 2×72.
Hence not 144°

y = (x - 3)^2 -9 + 7
y = (x - 3)^2 -2
y- 2 = (x - 3)^2
hence the vertex is at (3,2)
y = x² - 6x + 7 = x² - 2x · 3 + 3² - 3² + 7 = (x - 3)² - 9 + 7 = (x - 3)² - 2
Answer: y = (x - 3)² - 2
Used: (a - b)² = a² - 2ab + b²

Final answer:
The sum of the measures of ∠3 and ∠4 is 180°.
Explanation:
To find the sum of the measures of ∠3 and ∠4, we need to know the relationship between these angles and ∠1 and ∠2. If the sum of the measures of ∠1 and ∠2 is 180°, this means that these two angles are supplementary. In other words, they add up to 180°. Since angles ∠3 and ∠4 are corresponding angles with ∠1 and ∠2, they will also be supplementary to each other. Therefore, the sum of the measures of ∠3 and ∠4 is 180° as well.
