H(t)=- 16t^2 +16t+12 zeros of the parabola

Mathematics
1 answer:
igomit [66]3 years ago
8 0

Step-by-step explanation:

h(t) = -16t² + 16t + 12

h(t) = -4(4t² - 4t - 3)

h(t) = -4(2t - 3)(2t + 1)

When h(t) = 0, we have t = 1.5 or t = -0.5.

Hence the zeroes are 1.5 and -0.5.

What is an equation in point-slope form for the line that passes through the points (-3,5) and (2, -3)?
zloy xaker [14]

Answer:

y - 5 = -8/7(x + 3)

General Formulas and Concepts:

<u>Pre-Algebra</u>

Order of Operations: BPEMDAS

  1. Brackets
  2. Parenthesis
  3. Exponents
  4. Multiplication
  5. Division
  6. Addition
  7. Subtraction
  • Left to Right

<u>Algebra I</u>

Slope Formula: m=\frac{y_2-y_1}{x_2-x_1}

Point-Slope Form: y - y₁ = m(x - x₁)  

  • x₁ - x coordinate
  • y₁ - y coordinate
  • m - slope

Step-by-step explanation:

<u>Step 1: Define</u>

Point (-3, 5)

Point (2, -3)

<u>Step 2: Find slope </u><em><u>m</u></em>

Simply plug in the 2 coordinates into the slope formula to find slope <em>m</em>

  1. Substitute [SF]:                    m=\frac{-3-5}{2+5}
  2. Subtract/Add:                      m=\frac{-8}{7}

<u>Step 3: Write Equation</u>

<em>Plug in variables into the general form.</em>

y - 5 = -8/7(x + 3)

y + 3 = -8/7(x - 2)

Marsha got 100 on her first quiz and got an 85 on the rest of her quizzes for the semester. She got a total of 440 points on all
Veronika [31]

Answer:I think you are correct

Step-by-step explanation:

We know she got one 100

But we don't know how many 85's she got

So we put x with 85 so (85x) plus the only 100 she got

Leading us too 440
