Monica [59]

Answer:

Given below.

Step-by-step explanation:

1) Hypotenuse

2) Using Pythagoras theorem:

35² + 12² = c²

c = √1225+144

c = √1369

c = 37 ....this is the length of missing side.

Here given that opposite is 35 , adjacent is 12 , hypotenuse is 37.

3) sin(θ) = opposite/hypotenuse

sin(θ) = 35/37

4) cos(θ) = adjacent/ hypotenuse

cos(θ) = 12/37

5) tan(θ) = opposite/adjacent

tan(θ) = 35/12

Please don't take this down, it's just an innocent question

hichkok12 [17]

Answer:

False

Step-by-step explanation:

You can only get a two by rolling 2 ones

you can get a three by rolling a 1 and 2

They both only have 1 option to roll on too. So the answer is false, with 2 die the probibility will be the same.

Suppose the path of a baseball follows the path graphed by the quadratic function ƒ(d) = –0.6d2 + 5.4d + 0.8 where d is the hori

Vinil7 [7]

Answer:

Domain is all real numbers

Range is

$y\le 12.95$

Step-by-step explanation:

The given function is

$f(d)=-0.6d^2+5.4d+0.8$

This is a maximum quadratic function therefore the domain is all real numbers.

Let us complete the square to find the vertex.

$f(d)=-0.6(d^2-9d)+0.8$

$f(d)=-0.6(d^2+9d)+-0.6(\frac{9}{2})^2- -0.6(\frac{9}{2})^2+ 0.8$

$f(d)=-0.6(d-\frac{9}{2})^2+\frac{243}{20}+ 0.8$

$f(d)=-0.6(d-\frac{9}{2})^2+\frac{259}{20}$

Therefore the range is

$y\le \frac{259}{20}$

$y\le 12.95$

Check the picture below

you can pretty much get the values for "a" and "b" from the grid.
