Answer:

19km

Step-by-step explanation:

The formula for the perimeter of a triangle is: S+S+S.

So;

19km+19km+a=57km

a=57km-19km-19km

=19km

Answer:

y = (5-2x)/7 = 5/7 - 2x/7. option C

Step-by-step explanation:

here's your solution

=> 7y + 2x = 5

=> 7y = 5 - 2x

=> y = (5-2x)/7

Emmy throws a doggy toy up in the air. The path of the toy is modeled by the function f(x)=−x^2+4x+5, where x is the number of f

Molodets [167]

Answer:

9feet

Step-by-step explanation:

Given the path of the toy modeled by the function f(x)=−x^2+4x+5, where x is the number of feet the toy is from Emmy and f(x) is the height of the toy.

AT maximum height, the velocity of the toy will be zero. Hence;

df(x)/dx = 0

-2x + 4 = 0

-2x = -4

x = -4/-2

x = 2

Get the maximum height;

Substitute x = 2 into the given function;

f(x)=−x^2+4x+5

f(2)=−2^2+4(2)+5

f(2) = -4+8+5

f(2) = 9feet

Hence the maximum height of the toy is 9feet

15+0= 15

Ksju [112]

First of all, let's take a look on the question.

$\large{15 + 0 = 15}$

Here, 0 is added to 15 and the resultant is 15 only. So, we can say that 0 when added with any number gives the same number as the resultant.

So, the property is known as Identity property because 0 is added to get the identity of the same number.

The Correct Option:

$\large{ \boxed{ \red{ \bf{Option \: C}}}}$

So, let's know more...

Commutative property ➝ a + b = b + a
Associative property ➝ a + (b + c) = (a + b) + c
Distributive property ➝ a(b + c) = ab + ac

So this is the general form of these properties which is general observed in the rational numbers.
