Answer: r = 9

Given:

16=10+\sqrt{3r+27}

Step-by-step explanation:

16-10=\sqrt{3r+27}

6=\sqrt{3r+27}

Taking square on bothsides, we get

36=3r+27

3r=36-27

r=\frac{9}{3}

r=3

Answer:

r = 3.

Step-by-step explanation:

16 = 10 + √(3r + 27)

√(3r + 27) = 6

Square both sides:

3r + 27 = 36

3r = 36 - 27 = 9

r = 3.

Check the result:

Left side of the equation = 16

Right side = 10 + √(9 + 27)

                  = 10 + √36 = 16

A particle moves on a line away from its initial position so that after t hours it is s = 2t^2 +3t miles from its initial positi
Vaselesa [24]

Answer:

Average speed of the particle is 13 miles per hour.

Step-by-step explanation:

From the given question expression for distance traveled by the particle is

s=2t^{2}+3t

Then fro the time interval (1, 4) we have to calculate the average speed.

At t=1, s=2(1)²+3(1) =2+3 =5 miles

And at t = 4 s=2(4)²+3(4) = 2(16)+12 = 32+12 =44 miles

So displacement of the particle in the time span from 1 to hours.

s = (44-5) = 39 miles

And the times taken = (4-1) =3 hours

From the formula speed = displacement/(time taken for displacement)

V = 39/3 = 13 miles/hour

Diane works at a gardening store, and today she is helping assemble gas trimmers to be sold. An employee from an earlier shift a
Oxana [17]

The linear function for the number of trimmers assembled is:

y = 7 + 4x.

--------------------------------

A linear function has the following format:

y = ax + b

In which:

  • a is the rate of change.
  • b is the fixed amount.

--------------------------------

  • In an earlier shift, 7 trimmers had already been produced, thus 7 is the fixed amount, that is, b = 7.
  • Diane assembles 4 trimmers per hour, thus the rate of change is 4, that is, a = 4
  • The <u>amount of trimmers y produced after x hours</u> is given by:

y(x) = 4x + 7
