Answer (-1 , -8)

-----------------------------------
Check Equation -6(0.75)ˣ
-----------------------------------
when x = -1
y = -6(0.75)⁻¹
y = -6(4/3)
y = -8

When x = -1, y = -8, therefore this equation passes through (-1, -8)

-----------------------------------
Check Equation y = 4(x - 1)
-----------------------------------
When x = -1 
y = 4( - 1 -1)
y = 4(-2)
y = -8

When x = -1, y = -8, therefore this equation passes through (-1, -8)

-----------------------------------
Answer (B): (- 1, -8)
-----------------------------------

Does anyone know to do this!
Rina8888 [55]
Answer: (r + 4)(r + 8)
Alright, I would first rearrange the equation by bringing all your terms to one side by adding 12r and 32 to both sides. This will result in the rearranged equation: r^2+12r+32=0
You can then factor the equation into the two binomials: (r + 4)(r + 8).
4 + 8 equals the b term, 12, and 4 x 8 equals the c term, 32.

There is an antenna on the top of a building. From a location 300 feet from the base of the building, the angle of elevation to
san4es73 [151]

Answer:

Height of the antenna = 28 ft (Approx)

Given:

Length of base = 300 ft

Angle of elevation to the building = 40°

Angle of elevation to the antenna = 43°

Find:

Height of the antenna

Computation:

Using trigonometry function:

Tan40° = Height of building / Length of base

Height of building = 251.73 ft

Tan43° = [Height of building + Height of the antenna]  / Length of base

0.9325 = [251.73 + Height of the antenna] / 300

Height of the antenna = 28.02 ft

Height of the antenna = 28 ft (Approx)

Put in a new
mr_godi [17]

Answer:

$110

Step-by-step explanation:

The first step would be to multiply 11 and 5 to get the result of 55.

Then, you would multiply 55 by whatever the cost per square yard is, which in this case is $2.

Finally after multiplying 55 and 2 you would get the answer of $110.

Hope this helped! Have a great day! :)
