The coefficient of x² is is a negative 0.6, so this function has a maximum value.
the max value of a quadratic function is the value of f(x) when x=-b/2a,
in this case, a=-0.6, b=382
so x=382/1.2=
r(382/1.2)=-0.6(382/1.2)²+382*(382/1.2)
use a calculator: 60801.67 is the number I got.

Connor had 5 dogs with a mean of 44 ponds. What was the total weight of the five dogs?

IrinaVladis [17]

If all the dogs weighed the same, 44 would be the mean. The weight would be 44*5=220.

Hope this helped☺☺

What's the answer and how do u figure out number 5 only

shusha [124]

The length of a segment knowing the coordinates of its end points:
(x₁,y₁) and (x₂,y₂) is given by the formula:

Length = √[(x₁ - x₂)² + (y₁ - y₂)²]

T(1,4) ; A(4,4) ; P(3,0)

a) TA =√[(1-4)²+(4-4)²] → TA = 3
b) AP =√[(4-3)²+(4-0)²] →AP = √17 = 1.123
c) TP =√[(1-3)²+(4-0)²] → TA = √20 = 4.472

Perimeter = TA + AP + TP = 8.60

80 divided by (6 + (3 - 5) X 2)

a_sh-v [17]

Answer:

Step-by-step explanation:

remember PEMDAS

our equation looks like tihs: $\frac{80}{(6+(3-5)*2)}$

1. parentheses: in the denominator we have a parentese inside of another parenthese, so start with the inside first: (3-5) = -2.

so now our equation looks liek this $\frac{80}{(6-2 *2)}$

now we have a mini PEMDAS situation within the parentheses: multiplication comes before addition/subtraction, so multiply -2*2 = -4, so now your equation looks like this: $\frac{80}{(6-4)}$

6-4 =2: so now we're done with parentheses part of PEMDAS, the only thing left is dividing 80/2 which equals 40.
