iragen [17]

Answer:

B.) 27ft

Step-by-step explanation:

The labeled points given: (5,18) and (1.5, 7.5)

Slope = (18 - 7.5)/(5-1.5) = 10.5 / 3.5 = 3

A linear model:

y - 18 = 3(x - 5)

y - 18 = 3x - 15

y = 3x + 3

If x = 8 seconds then the distance in feet (y) would be: (plug in x = 8 into the equation y = 3x + 3)

y = 3(8) + 3

y = 24 + 3

y = 27 ft

Answer:

B.) 27ft

The expression 700(1.005644)4x shows the quarterly interest rate Letrice earns after x years. Which expression shows the x isola
shutvik [7]

Answer: 700( 1.02276784858 )^x

Step-by-step explanation:

Here, the given expression,

700(1.005644)^{4x }

Where x is the number of years.

We can write,

700(1.005644)^{4x } = 700[(1.005644)^4]^x  ( Because (a^m)^n = a^{mn} )

⇒ 700(1.005644)^{4x } = 700(1.02276784858)^x

Since, In the expression 700(1.02276784858)^x,  x is isolated in exponent and it is also equivalent to the given expression.

Therefore, it is our required answer.
