Vance is designing a garden in the shape of an isosceles triangle. The base of the garden is 30 feet long. The function y = 15 t
Sever21 [200]

Answer:

Part 1) The height of the triangle when θ = 30° is equal to 8.66\ ft

Part 2) The height of the triangle when θ = 40° is equal to 12.59\ ft

Part 3) The area of triangle with θ = 30° is less than the area of triangle with θ = 40°

Step-by-step explanation:

Part 1) What is the height of the triangle when θ = 30 ° ?

we have

y=15tan(\theta)

substitute the value of theta in the equation and find the height

y=15tan(30\°)=8.66\ ft

Part 2) What is the height of the triangle when θ = 40 ° ?

we have

y=15tan(\theta)

substitute the value of theta in the equation and find the height

y=15tan(40\°)=12.59\ ft

Part 2) Vance is considering using either θ = 30 ° or θ = 40 ° for his garden

Compare the areas of the two possible gardens

step 1

Find the area when θ = 30 °

The height is 8.66\ ft

Remember that the area of a triangle  is equal to the base multiplied by the height and divided by two

so

A=(1/2)(30)(8.66)=129.9\ ft^{2}

step 2

Find the area when θ = 40°

The height is 12.59\ ft

Remember that the area of a triangle  is equal to the base multiplied by the height and divided by two

so

A=(1/2)(30)(12.59)=188.85\ ft^{2}

Compare the areas of the two possible gardens

The area of triangle with θ = 30° is less than the area of triangle with θ = 40°

0=(2y−1)(8−y) Let y=u, y=d. What is the value of u×d
gulaghasi [49]

Answer:

The value of uxd=4

Step-by-step explanation:

since  y=u, y=d, y=y

y=1/2 and 8

2y-1=0

2y=1

y=1/2

8-y=0

8=y

1/2*8=4

What is the answer???
bonufazy [111]
First, change one of the equations to an y=x form I'll use the top one for example.
3x-2y=14
-2y=14-3x
y=-7+(3/2)x
Not that you can show what y is in terms of x, plug in the x side of the equation into the other equation, for y.
x+2(-7+(3/2)x)=10
Now, you can solve for x
x-14+3x=10
4x-14=10
4x=24
x=6
Using this value of x, we can now solve for y using one of the original equations.
(6)+2y=10
2y=4
y=2
