Find the density of a soda can with a radius of 3.25 cm, a height of 122 cm, and a mass of 40 g.
dimaraw [331]

Answer:

density = 9.88*10^{-3} g/cm^3

Step-by-step explanation:

Step 1: Volume of soda can

volume = \pi r ^{2}  h

=> \pi 3.25^{2}*122

volume = 4048.3cm^{3}

Step 2: Using answer from step 1 to calculate density

density=\frac{mass}{volume}

density = \frac{40}{\pi 3.25^{2}*122  }

density = 9.88*10^{-3} g/cm^3

Verify each of the following by evaluating the logarithms.<br> log10(103) + log10(104) = log10(107)
ioda

Answer:

log₁₀(10³) + log₁₀(10⁴)

= log₁₀( 10³ × 10⁴ )

= log₁₀( 10³⁺⁴)

= log₁₀( 10⁷)

Step-by-step explanation:

Given:

log₁₀(10³) + log₁₀(10⁴) = log₁₀(10⁷)

Now,

we know the property of log function that

log(A) + log(B) = log(AB)

therefore,

applying the above property on the LHS, we get

log₁₀(10³) + log₁₀(10⁴) = log₁₀( 10³ × 10⁴ )

also,

xᵃ + xᵇ = xᵃ⁺ᵇ

therefore,

log₁₀( 10³ × 10⁴ ) = log₁₀( 10³⁺⁴)

= log₁₀( 10⁷)

Hence,

LHS = RHS

Hence proved
