Part A:
Area of a circle is pi*radius^2
a=3.14*1^2
a=3.14
Part B:
Area of a rectangle is length*width
a=5*7
a=35
Part C:
Area of the shaded part would be the area of the rectangle - the area of the circle
a=35-3.14
a=31.86
Answer: y = 1 +/- 
<u>Step-by-step explanation:</u>
y² - 2y + 1 = x + 5
(y - 1)² = x + 5

y - 1 = +/- 
y = 1 +/- 
Answer:
x = 12
Step-by-step explanation:
The sum of exterior angles is = 360
one of the angle is given we will need to add all three angles
128 + 8x + 11x + 4 = 360 add like terms
19x + 132 = 360 subtract 132 from both sides
19x = 268 divide both sides by 19
x = 12 replace x in required expressions to find the measure of the angles
Answer:
There is a 25/81 probability that Grace will make both of her next two shots.
Step-by-step explanation:
The probability of her making the first shot is 5/9.
The probability of her also making the shot after that is still 5/9, that does not change.
To find the probability of both of those events, multiply the fractions.
5/9 * 5/9
25/81.
In step 2 .. because when you multiple by -4 in step 1 , the equation in step 2 will be ( -4y =-16 + 8z)
