stiv31 [10]

Answer:

$r=\sqrt {I}+10$

Step-by-step explanation:

We first need to know the square root of I then add 10 on that square root since r is 10 more than the square root of I

Find the zeros of the function: f(x) = x^2 - 4x - 21

IrinaK [193]

Answer:

x = 7, x = -3

Step-by-step explanation:

We can find the zeros by factoring the equation using the zero product property.

x^2-4x-21 = 0

(x-7)(x+3) = 0

x = 7

x = -3

Zeros are x=7 and x= -3.

the price of the cell phone is expected to increase by 165% in September 2015. The current price of a cell phone is $62.80. What

Sladkaya [172]

Answer:

$166.42.

Step-by-step explanation:

We have been given that the price of the cell phone is expected to increase by 165% in September 2015. The current price of a cell phone is $62.80.

The price of cell phone in September 2015 will be $62.80 plus 165% of $62.80.

$\text{The predicted cost of a cell phone in September 2015}=\$62.80+(\frac{165}{100}*\$62.80)$

$\text{The predicted cost of a cell phone in September 2015}=\$62.80+(1.65*\$62.80)$

$\text{The predicted cost of a cell phone in September 2015}=\$62.80+\$103.62$

$\text{The predicted cost of a cell phone in September 2015}=\$166.42$

Therefore, the predicted cost of a cell phone in September 2015 will be $166.42.
