Answer:

CD = 20 cm

Step-by-step explanation:

Area of Δ = 1/2(Base)(Height)

Where Height = 15, Area = 150

So,

150 = 1/2(CD)(15)

CD = $\frac{150*2}{15}$

CD = 10*2

CD = 20 cm

Write an equation of a parabola in vertex form. Vertex (2,-3) and passes through (0,5)

nydimaria [60]

Answer:

Step-by-step explanation:

The vertex form of a parabola is given by y = a(x - h)^2 + k, where (h, k) is the vertex.

Given vertex at (2,-3), h = 2, k = -3

y = a(x - 2)^2 + (-3) = a(x - 2)^2 - 3

The parabola passes through (0,5) so

5 = a(0 - 2)^2 - 3

5 = 4a - 3

4a = 8

a = 2

The parabola equation in vertex form:

y = 2(x - 2)^2 - 3

The area of the rug is 4 15/36 The rug is 2 3/4 meters in height How wide is the rug

sineoko [7]

I assume the rug is rectangle.

The area of rectangle is width (W) multiply by hight (H)

$A=4\frac{15}{36}=4\frac{5\cdot3}{12\cdot3}=4\frac5{12}\\\\H=2\frac34\\\\\\A=W\cdot H\\\\4\frac{5}{12}=W\cdot2\frac34\\\\4\frac5{12}:2\frac34=W\\\\ \frac{4\cdot12+5}{12}:\frac{2\cdot4+3}{4}=W\\\\ \frac{53}{12}:\frac{11}4=W\\\\ \frac{53}{12}\cdot\frac4{11}=W\\\\ \frac{53\cdot4}{3\cdot4\cdot11}=W\\\\W=\frac{53}{33}\\\\W=1\frac{20}{33}$

The rug is $1\frac{20}{33}$ meters wide
