A counterexample for the expression secФ / tanФ = sinФ is 45°
This is a FALSE statement.

Explanation:

Solving Right-hand side:

SecФ = 1 / CosФ

tanФ = SinФ / CosФ

secФ/tanФ = 1 / CosФ ÷ SinФ / CosФ

secФ/tanФ = 1 / CosФ × CosФ/SinФ

secФ/tanФ = CosФ / SinФCosФ

secФ/tanФ = 1 / SinФ

Hence,
            Left-hand side ≠ Right-hand side

starting at home, nadia traveled uphill to the grocery store for 30 minutes at just 4 mph. she then traveled back home along the
ankoles [38]
Distance from home to store = 4 * 0.5 = 2 miles.
Time taken to return home = (2/12) * 60 =10 minutes.
Total distance traveled = 2 * 2 = 4 miles.
Total time taken = 30 + 10 = 40 minutes.
Average speed for entire trip = total distance / total time in hours.
Average\ speed=\frac{4}{\frac{40}{60}}=\frac{4\times60}{60}=6\ mph

The side length of a square is blank meters find the area of the square and write your answer in simplest radical form.
elena-14-01-66 [18.8K]

Answer:

77+24\sqrt{10} m²

Step-by-step explanation:

Since it is a square, the side lengths are the same. Multiply the side lengths by each other to find the area.

(4\sqrt{2}+3\sqrt{5})(4\sqrt{2}+3\sqrt{5})

= 32+12\sqrt{10}+12\sqrt{10}+45

= 77+24\sqrt{10} m²

Original 350 new 400
BabaBlast [244]
I assume you are looking for the percent increase in which case you want to find the difference between original and new, then find the percentage of the original that gives you that difference... let me show you...

400 is the new value and 350 is the original value, so we have an increase of 400 - 350 = 50

So now we find what percentage of 350 is 50.

In math "of" means ×
"is" means =

x × 350 = 50
350x = 50
x = 50/350
x = .1429

multiply by 100 to convert to percent (move decimal to the right 2 places).

.1439 × 100 = 14.29%

So the percentage of increase is 14.29%
