Ronald was charged a dollar extra for each ticket
The value of the scale factor is 3. Then the height and area of the triangle ΔABC will be 9 ft and 54 square ft.
<h3>What is dilation?</h3>
Dilation means the changing of the size of the object without changing the shape. The size of the object may be increased or decreased based on the scale factor.
The area of the triangle ΔDEF is 6 square ft. And the base length of the triangle ΔDEF is 4 ft.
The area of the triangle is given as
Then the height of the triangle ΔDEF will be
Then the scale factor will be
Then the height of the triangle ΔABC will be
Then the area of the dilated triangle ΔABC will be

Answer:
each balloon costs 1$ and each banner costs 3$
Step-by-step explanation:
Answer:
b=11 a=-2
Step-by-step explanation:
4=x and 7=y and 4+7=11
a(4)+3(7)=13
4a+21=13
-21 -21
4a=-8
÷4 ÷4
a=-2
This is not an identity.
Check x = π/4, for which we have cos(π/4) = sin(π/4) = 1/√2. Together with sin(2•π/4) = sin(π/2) = 1 and cos(2•π/4) = cos(π/2) = 0, the left side becomes 1, while sec(π/4) = 1/cos(π/4) = √2.
Keeping the left side unchanged, the correct identity would be
To show this, recall
• sin(2x) = 2 sin(x) cos(x)
• cos(2x) = cos²(x) - sin²(x)
• cos²(x) + sin²(x) = 1
Then we have
