My answer would be A. Because if your line is going down, it is a negative slope. And the y-intercept is at negative 1.

Which of the following is true for the interval from 3-5 seconds

kondaur [170]

Answer:

Option C

Step-by-step explanation:

The given function is: $h(t)=-16t^2+80t+108$ .

$h(5)=-16(5)^2+80(5)+108=108$ .

$h(3)=-16(3)^2+80(3)+108=204$ .

The average rate of change of this function on the interval t=3 to t=5 is given by:

$\frac{h(5)-h(3)}{5-3}$

$\frac{204-108}{2}=-48$

Since the average rate of change is negative on the interval 3-5 seconds, it means the ball is moving downwards at an average rate of 48 feet per second.

The correct choice is C.

3 plus 27 divided by (4 plus 5) Find the sum 1/3 plus 2/5

dezoksy [38]

Answer:

4.) 6

5.) $\frac{11}{15}$

Step-by-step explanation:

PEMDAS

Parenthesis, Exponents, Multiplication, Division, Adition, Subtraction.

3 + 27 ÷ ( 4 + 5 )

Do the parenthesis first ( 4 + 5 )

3 + 27 ÷ 9

Do the division next ( 27 ÷ 9)

3 + 3

Now addition.....( 3 + 3)

__________________________________________________________

$\frac{1}{3} + \frac{2}{5}$

In order to find the sum between these 2 fractions, we need to find a common denominator, and in this case, it can be 15...

$\frac{1 * 5}{3 * 5} = \frac{5}{15}$

$\frac{2 * 3}{5 * 3} = \frac{6}{15}$

Now that we have a common denominator, we can add them up...

$\frac{5}{15} + \frac{6}{15} =\frac{11}{15} \\\\\frac{11}{15}$

$\frac{11}{15}$ is ur answer.

Hope this helped!

Have a supercalifragilisticexpialidocious day!
