A new underground rollercoaster is being installed. The height of the rollercoaster in feet throughout the underground section is modeled by the equation h(d) = 0.15d2 – 1.5d, where d represents horizontal distance in feet. What's the height of the rollercoaster 6 feet horizontally through the underground section?

Answers

Answer 1

Answer:

3.6 feet

Step-by-step explanation:

The height of the rollercoaster in feet throughout the underground section is modeled by the equation :

[tex]h(d) = 0.15d^2 - 1.5d[/tex] ....(1)

We need to find the height of the rollercoaster 6 feet horizontally through the underground section.

Put d = 6 feet in equation (1) as follows :

[tex]h(6) = 0.15(6)^2 - 1.5(6)\\\\h=-3.6\ \text{feet}[/tex]

or

h = 3.6 feet

So, the height of the rollercoaster 6 feet horizontal through the underground section is 3.6 feet.

A triangle has sides with lengths of 6 millimeters, 8 millimeters, and 11 millimeters. Is it a
right triangle?

Answers

Answer:

No

Step-by-step explanation:

Using the converse of Pythagoras' identity.

If the square on the longest side is equal to the sum of the squares on the other 2 sides, then the triangle is right.

longest side = 11

11² = 121

6² + 8² = 36 + 64 = 100 ≠ 121

Thus the triangle is not right.

Which statement about the linear factors and zeros of a quadratic function is always true? The constants of the linear factors are the opposite of the function's zeros. A function's zeros can be determined by setting each linear factor equal to 0 and solving. If a function's zero is an integer, then the coefficient of the variable in the linear factor must be one. Multiplying the constants of the linear factors gives one of the function's zeros, and adding the constants gives the other zero.

Answers

Answer:

A function's zeros can be determined by setting each linear factor equal to 0 and solving.

Step-by-step explanation:

This is because in finding the zero's of a quadratic function, we factorize the quadratic function to obtain its linear factors. Then, each linear factor is then equated to zero to solve for the zeros of the quadratic function.

The solution of the equating to zero of the linear factors give the zeros of the quadratic function.

What is the value of b in the equation

Answers

Answer:

b = - 6

Step-by-step explanation:

Using the rules of exponents

[tex](a^{m}) ^{n}[/tex] ⇔ [tex]a^{mn}[/tex]

[tex]a^{-m}[/tex] = [tex]\frac{1}{a^{m} }[/tex]

Thus

[tex](y^{b}) ^{4}[/tex] = [tex]y^{4b}[/tex] = [tex]\frac{1}{y^{24} }[/tex] = [tex]y^{-24}[/tex], then equating the exponents

4b = - 24 ( divide both sides by 4 )

b = - 6
