Answer:
Step-by-step explanation:
AR = QR = RS = (1/2) QS = 3
So ....by the Pythagorean Theorem, AS = AQ =
√ [3^2 + 3^2] = √[9 + 9 ] = √18
And the area of the two semi-circles= the area of a circle with a radius of AS/2 =
pi [AS/2]^2 =
pi [√18/2]^2 = 18pi/4 = (9/2)pi units^2
And the area of the rest of the figure is just that of a rhombus =
The product of the diagonals / 2 =
AB*QS/2 = 9 * 6 / 2 = 27 units^2
So....the total area =
[(9/2) pi + 27] units^2 = about = 41.1 units^2 [rounded]
The equation of a line is written in form y = Mx+ b
M is the slope, also known as the gradient.
You are given the gradient and one point , which is an x and y value. Using that solve for b:
1. Gradient = 2, x = 4, y= 3
3 = 2(4) + b
3 = 8 + b
Subtract 8 from both sides:
B = -5
The equation becomes y = 2x-5
2. Gradient = -3, x= -1, y = 7
7 = -3(-1) + b
7 = 3 + b
Subtract 3 from both sides:
B = 4
Equation becomes: y = -3 +4
Answer: $25,500
<u>Step-by-step explanation:</u>
The given sequence {1300, 1300+150, ... } provides the following information:
- the first term (a₁) = 1300
- the difference (d) = 150
We can use the information above to find the explicit rule of the sequence:
We can use the explicit rule to find the 12th term (a₁₂)
Next, we can input the first and last term of the sequence into the Sum formula:
Answer:
OK I am 85% sure on this for the 13 year old its ( 23 to 112 )
and for the older kids ( 147 to 48 ) or (23:112) (147:48)
hope it helps if it doesn't sorry.
