h(t) = –16t2 + 202.5
h(t) = –16t2 + 56t + 5
h(t) = –16t2 + 56t + 6.5
Answers
Answer:
D
Step-by-step explanation:
Edge 2020-2021
The quadratic equation {y = - 16t² + 202.5} correctly represents the given graph.
What is a quadratic equation?A quadratic equation is of the form -
f(x) = ax² + bx + c
Given is the graph as shown in the image attached.
The graph given in the image is correctly represented by the quadratic equation -
y = - 16t² + 202.5
Due to the negative coefficient of {a}, it opens downwards. The [y] intercept is at 202.5.
Therefore, the quadratic equation {y = - 16t² + 202.5} correctly represents the given graph.

Subtract 5x^2+8x-11 from 3x^2+8x-7
Answers
Explanation: First you’d need to rewrite the equation as (3x^2+8x-7)-(5x^2+8x-11). Then since you are subtracting, distribute the negative to the right side which will then give you -5x^2-8x+11 since you flip the signs. Then simply combined like terms. -5x^2 + 3x^2 is -2x^2. Then 8x-8x is 0 and lastly, +11-7 is 4. So in order, all together, your answer is -2x^2+4.
factorise the following:
[tex]{3x}^{2} + 5x - 12[/tex]
Answers
Answer:
(x + 3)(3x - 4)
Step-by-step explanation:
Given
3x² + 5x - 12
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 3 × - 12 = - 36 and sum = + 5
The factors are + 9 and - 4
Use these factors to split the x- term
3x² + 9x - 4x - 12 ( factor first/second and third/fourth terms )
= 3x(x + 3) - 4(x + 3) ← factor out (x + 3) from each term
= (x + 3)(3x - 4)
Thus
3x² + 5x - 12 = (x + 3)(3x - 4) ← in factored form

Answers
Answer:
1. 2
2.circle
3.b tan t
Step-by-step explanation:
The slope of the equations x = 1 + 3t and y = -1 + 6t is 6, the equations x = 5 cos t and y = 5 sin t describe a circle and if x = a sec t is one of the parametric equations, the other will be y =b tan t
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The equation x = 1 + 3t and y = -1 + 6t can be expressed in the form y = mx + b, where m is the slope and b is the y-intercept.
In this case, m = 6, which is the slope of the line.
The equations x = 5 cos t and y = 5 sin t describe a circle.
These equations define the parametric form of a circle with a radius of 5 centered at the origin.
if x = a sec t is one of the parametric equations, the other will be y =b tan t
Hence, the slope of the equations x = 1 + 3t and y = -1 + 6t is 6, the equations x = 5 cos t and y = 5 sin t describe a circle and if x = a sec t is one of the parametric equations, the other will be y =b tan t
