Answer:

Step-by-step explanation:

Area of the rectangle

A = base x width = 8 x 6 = 48 cm^2

Area of the triangle

A = (base x height)/2 = (6 x 4)/2 = 12 cm^2

two semicircles are equal to a circle

radius = diameter / 2 = 3/2 = 1.5 cm

A = radius^2 x pi = 1.5^2 x pi = 7 cm^2 (round to the nearest whole number)

total area

48 + 12 + 7 = 67 cm^2

Find the x-intercepts of the parabola with vertex (1,-108) and y-intercept (0,-105). Write your answer in this form: (X1,y1), (x

Stolb23 [73]

Answer:

(7, 0) and (-5, 0)

Step-by-step explanation:

<u>Vertex form</u>

$y=a(x-h)^2+k$

(where (h, k) is the vertex)

Given:

vertex = (1, -108)

$\implies y=a(x-1)^2-108$

Given:

y-intercept = (0, -105)

$\implies a(0-1)^2-108=-105$

$\implies a(-1)^2=-105+108$

$\implies a=3$

Therefore:

$\implies y=3(x-1)^2-108$

The x-intercepts are when y = 0

$\implies 3(x-1)^2-108=0$

$\implies 3(x-1)^2=108$

$\implies (x-1)^2=36$

$\implies x-1=\pm \sqrt{36}$

$\implies x=1\pm 6$

$\implies x=7, x=-5$

Therefore, the x-intercepts are (7, 0) and (-5, 0)
