Answer:

+-+

Step-by-step explanation:

C. 1,300

I cant see the expression but i got 1,100 by finding out what 80% of 1500 is by multiplying 1500 by 0.8 to get 1,200. Then add the 100 that you have to pay for the membership +to get a total of $1,300. hop dat dis iz help fuuull

Identify the maximum value of the function y = -472 - 24x + -36.
Gnesinka [82]

Answer:

I assume that this is a quadratic equation, something like:

y = -47*x^2 - 24x + (-36)

we can rewrite it as:

y = -47x^2 - 24x - 36

Ok, this is a quadratic equation and we want to find the maximum value.

First, you can notice that the leading coefficient is negative.

This means that the arms of the graph will open downwards.

Then we can conclude that the vertex of the equation is the "higher" point, thus the maximum value will be at the vertex.

Remember that for a general function

y = a*x^2 + b*x + c

the vertex is at:

x = -b/2a

So, in our case:

y = -47x^2 - 24x - 36

The vertex will be at:

x = -(-24)/(2*-47) = -12/47

So we just need to evaluate the function in this to find the maximum value.

Remember that "evaluating" the function in x = -12/47 means that we need to change al the "x" by the number (-12/47)

y = -47*(-12/47)^2 - 24*(-12/47) - 36

y = -32.94

That is the maximum value of the function, -32.94

Plz help!!!
kipiarov [429]

Answer:

To determine its end behavior, look at the leading term of the polynomial function. Because the power of the leading term is the highest, that term will grow significantly faster than the other terms as x gets very large or very small, so its behavior will dominate the graph. For any polynomial, the end behavior

Answer:

5\dfrac{1}{2}\ \text{kg}

Step-by-step explanation:

Plant food used on strawberry plants is

1\dfrac{2}{3}\ \text{kg}=\dfrac{5}{3}\ \text{kg}

Plant food used on tomato plants is

\dfrac{1}{4}\ \text{kg}

Feeding the strawberry plants two times means

\dfrac{5}{3}+2\times\dfrac{5}{3}=\dfrac{5}{3}+\dfrac{10}{3}\\ =\dfrac{15}{3}=5\ \text{kg}

Feeding the tomato plants one more time means

\dfrac{1}{4}+\dfrac{1}{4}=\dfrac{2}{4}\\ =\dfrac{1}{2}\ \text{kg}

The plant food he will need is 5+\dfrac{1}{2}=5\dfrac{1}{2}\ \text{kg}
