Mathematics
1 answer:
olga_2 [115]3 years ago
3 0

Answer:

Step-by-step explanation:

You first want to get rid of the numbers which are in parenthesis

(-345(-23)

This is a multiplication between negative numbers

The law of signs in mathematics states that negative times negative equals positive

(-) (-) = +

(-345(-23)= 7935

Then we multiply the number which is outside of the parenthesis (4x)

(4x)7935= 31740x

When will the equation p(b)=520(0.88)^b have a value less than 100?
yulyashka [42]

Answer:

The given equation will have value less than 100 whenever the value of b is greater than 12.89

Step-by-step explanation:

For the given equation, p(b) = 520 × 0.88^{b} to have a value less than 100 we can establish inequality as:

                     p(b) < 100

         or,  520 × 0.88^{b} < 100

         or, \frac{520}{520} × 0.88^{b} < \frac{100}{520}

         or, 0.88^{b} < \frac{1}{5.2}

         or, ㏒ ( 0.88^{b} ) < ㏒  (\frac{1}{5.2})

         or, b× ㏒ 0.88 < ㏒  (\frac{1}{5.2})

         or,  \frac{log (\frac{1}{5.2}) }{log (0.88)}   <  b

         or, 12.89 < b

Hence for the equation to have value less than 100, b must be greater than 12.89.
