You need the Law of Cosines here, since you only have 1 angle measure. If you had 2 you could use the Law of Sines, but nevertheless, we'll get there. The Law of Cosines for our particular set of info looks like this: $x^2=65^2+41^2-2(65)(41)cos(35)$ . Simplifying a bit we get $x^2=4225+1681-4366.080396$ and $x^2=1539.9196$ . Taking the square root of that and considering the principle root only, x = 39.2, second choice down.

Given 2x^2=-8, x is<br><br> A.-2<br> B. 2<br> C. 2i or -2i<br> D. 4i or -4i

Lera25 [3.4K]

Answer:

2i or -2i

Step-by-step explanation:

2x² = -8 First, clear x.

x² = -8/2 Solve

x² = -4 Now, eliminate the square of x by solving the square root of -4.

x = √-4

x = 2i or -2i Is an imaginary number.

the density of a substance is 2.5 cm calculate the volume of the substance if its mass is 25.0 grams

sesenic [268]

Answer:

10 cm³

Step-by-step explanation:

The equation for density is: d = m/v, where d is the density, m is the mass, and v is the volume.

Here, d = 2.5 and m = 25.0, so plug these into the equation to solve for v:

d = m/v

2.5 = 25/v

Multiply both sides by v:

2.5v = 25

Divide by 2.5:

v = 25/2.5 = 10

Thus, the volume is 10 cm³.
