Answer:

The given expression will be greater than zero.

Step-by-step explanation:

If a < 0 and b < 0, then 5a^3 is < 0 (5a^3) is negative;

but b^2 is > 0.

Then (5a^3)*(b^2) < 0

and if we divide this quantity by a + b (which is negative), the end result will be > 0.

galina1969 [7]
We know that h = 65 ft and the angle of elevation to the top is α = 56°.
x - the length of the support wire;
x · cos 56° = 65
x = 65 / cos 56°
x = 65 / 0.5592
x = 116.237 ≈ 116.2 ft ( to the nearest tenth )
Answer:  The support wire is 116.2 ft long.

lilavasa [31]

Answer:The total cost for the car including tax is $27423.75

6.5/100 × 25750 = 0.065 × 25750 = 1673.75

The total cost for the car including tax would be the sum of the initial cost of the car and the amount of tax. It becomes

25750 + 1673.75 = $27423.75
