Answer:

1) 180 is a straight line, so 180 - 118 = 62

2) 180 degrees are in a triangle, so 180 - (62) - 73 = 45

3) 180 is a straight line, so 180 - 73 = 107. There are 180 degrees in a triangle, so 180 - 49 - 45 = 86

Use a net to find the surface Area of the square pyramid The height of the pyramid is 9 yes and the base sides are all 2.5 yrds

Cerrena [4.2K]

Answer:

$Area = 51.68yd^2$

Step-by-step explanation:

Given

$h = 9yd$ -- height

$a = 2.5yd$ --- base sides

Required

Determine the surface area

The net is not given. So, I will solve directly.

The surface area is calculated as:

$Area = a^2 + 2a\sqrt{\frac{a^2}{4} + h^2}$

So, we have:

$Area = 2.5^2 + 2*2.5\sqrt{\frac{2.5^2}{4} + 9^2}$

$Area = 6.25 + 5\sqrt{\frac{6.25}{4} + 81}$

$Area = 6.25 + 5\sqrt{1.5625 + 81}$

$Area = 6.25 + 5\sqrt{82.5625}$

$Area = 6.25 + 5* 9.086$

$Area = 51.68yd^2$

Which translation maps the vertex of the graph of the function f(x) = x2 onto the vertex of the function g(x) = x2 + 2x +1?

jarptica [38.1K]

Answer:

Option B is correct

Left 1 unit.

Explanation:

According to the graph theory of transformation:

y = f(x+k)= $\left \{ {{k>0 shift graph of y= f(x) left k unit} \atop {k$

Given the parent function: $f(x)=x^2$

and the function $g(x)=x^2+2x+1$

we can write it as:

g(x)= $(x+1)^2$ [ ∴ $(a+b)^2 = a^2+2ab+b^2$ ]

Therefore, vertex of the graph of the function $g(x)=(x+1)^2$ is 1 units to the left of the vertex of the graph of the function $f(x)=x^2$ .
