determine the maximum or minimum of the quadratic function. express your answer in the form (x,y) and using decimals rounded to
kolezko [41]

We are given the following quadratic equation

f(x)=2x^2+7x-10

The vertex is the maximum/minimum point of the quadratic equation.

The x-coordinate of the vertex is given by

h=-\frac{b}{2a}

Comparing the given equation with the general form of the quadratic equation, the coefficients are

a = 2

b = 7

c = -10

h=-\frac{b}{2a}=-\frac{7}{2(2)}=-\frac{7}{4}=-1.75

The y-coordinate of the vertex is given by

\begin{gathered} f(x)=2x^2+7x-10 \\ f(-1.75)=2(-1.75)^2+7(-1.75)-10 \\ f(-1.75)=2(3.0625)^{}-12.25-10 \\ f(-1.75)=6.125^{}-12.25-10 \\ f\mleft(-1.75\mright)=-16.13 \end{gathered}

This means that we have a minimum point.

Therefore, the minimum point of the given quadratic equation is

(-1.75,-16.13)

4. Mr. Ramos invests $600 at a simple interest rate of 6%. How much interest will he earn in one year?
lora16 [44]

Answer:

$36 if it's an annual rate. If it's a monthly rate it's $432

Step-by-step explanation:

Since it's such a high interest rate to pay, I think the logical rate would be annually because that's a lot of money for a bank to give

The leg of a triangle is 7 cm and the hypotenuse is 13 cm. What is the length of the other leg of the triangle?
defon

Answer:

2√30

Step-by-step explanation:

Pythagorean Theorem: a^2 + b^2 = c^2

7^2 + b^2 = 13^2

b^2 = 120

b = 2√30

Select the correct answer.
Anna11 [10]

Using a linear function, it is found that Company D would have given you the best deal for 7 hours of moving.

<h3>What is a linear function?</h3>

A linear function is modeled by:

y = mx + b

In which:

  • m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
  • b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.

In this problem, we consider:

  • The flat fee as the y-intercept.
  • The hourly rate as the slope.

Hence the costs for x hours of moving from each company are given as follows:

  • A(x) = 50 + 25x.
  • B(x) = 40 + 30x.
  • C(x) = 60 + 20x.
  • D(x) = 150 + 5x.

For 7 hours, the costs are given as follows:

  • A(7) = 50 + 25 x 7 = $225.
  • B(7) = 40 + 30 x 7 = $250.
  • C(7) = 60 + 20 x 7 = $200.
  • D(7) = 150 + 5 x 7 = $185.

Due to the lower cost, Company D would have given you the best deal for 7 hours of moving.
