Answer is 1,563 feet. Hope this helps.
Answer:
(1)
Step-by-step explanation:
x - 2 = - 5 Add 1 to each side
x = - 5 + 2
x = - 3
Now go to the next part
(x - 2)^2
(-3 - 2)^2
(- 5)^2
Now it's a good idea at this point to separate the squared. It means that two numbers that are the same are to be multiplied together.
(-5)(-5) Two minuses are going to give you a plus.
5 * 5 = 25
(-5) * (-5) also give you 25
The answer is (1)
Step 1:
<span>Calculate the effective thermal conductivity of the wall or ceiling:
</span>
K_eff = [ (13 ÷ 8)(0.12) + (16 - (13 ÷ 8)) × (0.04)] ÷ 16
K_eff =<span> [ 0.195 + 0.565] </span>÷<span> 16
</span>
K_eff = 0.76 ÷ 16
K_eff = 0.0475 W/ (m K)
Step 2:
Calculate <span>the interior ceiling area:
</span>Area of each of the interior side walls = <span>8.82 m x 8.64 m
= 76.2 m</span>²
Area of the interior ceiling = 8.64 m × <span>8.64 m
</span> = 74.6 m²
H = - k·A·(Δ - T) ÷ <span>(thickness)
</span>
H = - 0.0475 ÷ (379.45 × 20) ÷ 45/8
H = - ( - 0.95 × 379.45 ) ÷<span> 0.1429
</span>
H = <span>2.52 kW </span>
A; it decreased by about 800, which is roughly 25% of 3200.
Answer:
B
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 1, 1) and (x₂, y₂ ) = (1, - 3) ← 2 points on the line
m = = = - 2
Note the line crosses the y- axis at (0, - 1) ⇒ c = - 1
y = - 2x - 1 or
f(x) = - 2x - 1
