Slope-intercept form:
y = mx + b "m" is the slope, "b" is the y-intercept (the y value when x = 0)
Since you know m = 7/2, plug it into the equation
y = 7/2x + b
To find "b", plug in (-12,-9) into the equation
y = 7/2x + b
-9 = 7/2(-12) + b
-9 = -84/2 + b
-9 = -42 + b Add 42 on both sides
33 = b
(if you're not suppose to use slope-intercept form)
Point-slope form:
y - y₁ = m(x - x₁)
m = 7/2
(x₁ , y₁) = (-12,-9)
Plug this into the equation
y - y₁ = m(x - x₁)
y - (-9) = 7/2(x - (-12))
The answer for missing angle S is 60°
Answer:
Surface area = 39 yards²
Step-by-step explanation:
∵ the surface area of the pyramid = 1/2 pl + base area
Where p = perimeter of the base , l = slant height
∵ Area of the base = 3 × 3 = 9 yards²
∵ Perimeter of the base = 4 × 3 = 12 yards
∵ Slant height = 5 yards
∴ The surface area = 1/2 × 12 × 5 + 9 = 39 yards²
Answer:
79.617...
Step-by-step explanation:
When you are trying to find the circumfrence you do c=πd
So to find the diameter you reverse it
Since you already know the 250 feet you divide it by π
You then get 79.6
