Answer:
(d) (7, -5)
Step-by-step explanation:
The x-coordinate is listed first in an ordered pair. It is found on the horizontal scale. The point is on the grid line halfway between 6 and 8, so is presumed to have an x-coordinate of 7.
The y-coordinate is listed second in an ordered pair. It is found on the vertical scale. The point is on the grid line halfway between -4 and -6, so is presumed to have a y-coordinate of -5.
The coordinates of point A are (x, y) = (7, -5).

<em>Additional comment</em>
As in the case here, you will often run across graphs that don't have markings on every grid line You are expected to be able to figure out the value of a grid line based on the spacing of the marked lines.
It is a good idea to get familiar with reading coordinates of a point on a graph, as you will be doing it a lot.
Answer:
30.89cm³
Step-by-step explanation:
Given that:
Side length, s of square = 12cm
Area of square = s² = 12² = 144cm²
Since the circle touches the edge of tbe square, then the diameter of the circle = side length of square = 12 cm
Area of a circle = πr²
Radius, r = diameter / 2 = 12/2 = 6cm
A = 3.142 * 6^2
A = 3.142 * 36
A = 113.112 cm²
Area of shaded portion = area of square - area of circle
= 144cm² - 113.112cm³
= 30.89cm³
Answer:
3(5)^x-1
Step-by-step explanation:
I'm assuming that the y term 3 is the first term in the sequence which would mean that your first number in the equation would be 3. then, you find the slope of the sequence (5) so your equation is now five times three. Then you would raise it to the power of (x) and subtract one from x because 3 is not the y intercept but in fact the first term.
Answer:
73.6
Step-by-step explanation:
5% of x = 23
.05 x = 23
divide by .05 on each side
x = 23/.05
x = 460
16 % of 460
.16 * 460 =
73.6
OR
16% is 5% +5% +5% +1%
= 23+23+23+4.6
= 73.6
Answer :
(-4,0)
