This is a simple Pythagorean theorem, which says that c2 = a2 + b2
So let us just apply it here:
c^2 = 4^2 + 4^2
c^2 = 16 + 16
c^2 = 32
c = <span>√32
c = </span><span>√2*16
c = 4</span><span><span>√2
</span>The correct answer is c = 4</span><span>√2.</span>
Answer:
v = 23
Step-by-step explanation:
Formatting the question gives;
a = mg - kv² / m
Make v subject of the formula as follows;
(i) Multiply both sides by m
ma = m²g - kv²
(ii) Collect like terms
kv² = m²g - ma
(iii) Divide through by k
v² = (m²g - ma) / k
(iv) Take the square root of both sides
v = √ [(m²g - ma) / k] --------------(ii)
From the question:
a = 2.8
m = 12
g = 9.8
k = 8/3
Substitute these values into equation (i) as follows;
v = √ [(12²(9.8) - 12(2.8)) / (8/3)]
v = √ [(1411.2 - 33.6) / (8/3)]
v = √ [1377.6 / (8/3)]
v = √ [1377.6 x (3/8)]
v = √ [1377.6 x 3 / 8)]
v = √ [516.6]
v = 22.73
v = 23 [to the nearest whole number]
Therefore v = 23 to the nearest whole number

Answer:
Step-by-step explanation:
If it has a slope of 3/4, then it will look like this:
If it passes through (4, 0), than y = 0 when x = 4
Therefore, the equation is .
