Answer:
Step-by-step explanation:
<u>Let the area of initial square is x, then shaded squares will have area as geometric sequence:</u>
The first term is x, the common ratio is 1/4
<u>Sum of infinite GP is:</u>
<u>By substituting values we get:</u>
- S = x/(1 - 1/4) = x / (3/4) = 4x/3
Answer:
-3
Step-by-step explanation:
So they are essentially giving you x, so you replace it with -3.
H(-3) = 2/3 (-3) -1
2/3 × -3 = -2
-2 - 1 = -3
H(-3) = -3 ⬅This is a true statement.
Hope this helps :)
Answer:
<u>254.34 in²</u>
Step-by-step explanation:
<u>Area of a circle</u>
- <u>r = radius of the circle</u>
<u>Solving</u>
- A = 3.14 x (9)²
- A = 3.14 x 81
- A = <u>254.34 in²</u>
The Triangle's Perimeter=24cm
Each side of the triangle =24cm/3=8cm. Each length of the square=8cm-2.5cm=5.5cm. Perimeter of a square =4l
The perimeter is 22cm
X intercepts means y = 0.
So, just equals the equation to 0 and solve for x.
For example, if the equation is a parabola, y = ax^2 + bx + c, make
ax^2 + bx + c = 0.
You can solve that equation using the quadratic formula:
- b +/- √ [ b^2 - 4(a)(c) ]
x = --------------------------------
2(a)
Replacing a, b and c will give you the roots of the polynomial which are the x-intercepts.
