-5(1 - r) - 2<br> Find r
Grace [21]

Answer:

-5+5r-2 -->

--> 5r-7 <--

Explanation --

Distribute from the parentheses, of course excluding the -2 because it isn't involved, and you'll get --> -5 + 5r -2

Simplify by putting the like terms together (subtract) -->

5r -7 (you get -7 by doing -5-2, and you leave 5r by itself since it doesn't have anything more to simplify with or has any other like term)

So, the final, simplified answer -->

5r-7

Hope this helps!! Have a nice day! :)

1.) Use the Pythagorean Theorem to determine if a triangle with side lengths 28ft., 45ft., 53ft. is a right triangle.
Alenkasestr [34]

Answer:

1. Right Triangle

2. Not Right Triangle

3. Not Right Triangle

Step-by-step explanation:

1. 28² + 45² = 2809 --> 53² = 2809

2. 6² + 6² = 72 --> 8² = 64

3. 4² + 10² = 116 --> 12² = 144

the function f is defined by f(x)=150/x-z where z is a constant. find z if the value of f at x=1/5 is equal to 250
malfutka [58]

Answer:

x = -1 \frac{1}{20}

Step-by-step explanation:

f(\frac{1}{5}) = 120, therefore we can create this equation:

120 = 150 ÷ (\frac{1}{5} - z)

cross-multiply to get: 24 - 120z = 150

-120z = 126

z = -1 \frac{3}{60}

The path of a football can be modelled by the equation, h=-10d2+120d , where h represents the height, in metres, of the football
Marta_Voda [28]

Answer:

12 m

Step-by-step explanation:

The path of a football has been modeled by the equation:

h= -10d^2+120d

where h represents the height and d represents the horizontal distance.

When the ball lands, it means that its height is back at 0 metres. This means that we have to find horizontal distance, d, when height, h, is 0.

=> 0= -10d^2+120d

=> 10d^2 - 120d = 0

d(10d - 120) = 0

∴ d = 0 m

and

10d - 120 = 0

=> d = 120 / 10 = 12 m

There are two solutions for d when h = 0 m.

The first solution (d = 0 m) is a case where the ball has not been thrown at all. This means the ball has not moved away from the football player and it is still on the ground.

The second solution is the answer to our problem (d = 12 m). The ball lands at a horizontal distance of 12 m
