Solve -1.0*10^-7*10*0.48*sin30^circ

$$- 1.0 \times 10 ^ { - 7 } \times 10 \times 0.48 \times \sin 30 ^ { \circ }$$

Evaluate

$$-0.00000024$$

Solution Steps

To multiply powers of the same base, add their exponents. Add 1 and -7 to get -6.

$$0.48\times 10^{-6}\left(-1\right)\sin(30)$$

Calculate 10 to the power of -6 and get \frac{1}{1000000}.

$$0.48\times \frac{1}{1000000}\left(-1\right)\sin(30)$$

Multiply 0.48 and \frac{1}{1000000} to get \frac{3}{6250000}.

$$\frac{3}{6250000}\left(-1\right)\sin(30)$$

Multiply \frac{3}{6250000} and -1 to get -\frac{3}{6250000}.

$$-\frac{3}{6250000}\sin(30)$$

Get the value of \sin(30) from trigonometric values table.

$$-\frac{3}{6250000}\times \frac{1}{2}$$

Multiply -\frac{3}{6250000} and \frac{1}{2} to get -\frac{3}{12500000}.

$$-\frac{3}{12500000}$$
