The answer is <span>f(x) = 2x2 + 3x – 3
</span>
f(x) = ax² + bx + c
a - the leading coefficient
c - the constant term
<u>We are looking for a = 2, c = -3</u>
Through the process of elimination:
The first (f(x) = 2x3 – 3) and the third choice (f(x) = –3x3 + 2) have x³ so these are not quadratic function.
In the function: <span>f(x) = –3x2 – 3x + 2
</span>a = -3
c = 2
In the function: f(x) = 2x2 + 3x – 3
a = 2
c = -3
Let's solve this using unitary method ~
Therefore , the ostrich will run 105 meters in 5 seconds.
Answer:
29
Step-by-step explanation:
a+b+b+c+a+c=58
2a+2b+2c=58
divide by 2
a+b+c=29
Answer:
405 are not expected to be alive in the next year
180m
To find this we need to find the perimeter. The perimeter is not given so we need to find it. If the land is square we can assume all sides are the same length. So to find the perimeter we need to find the side length. So we find the square root of the volume. The square root of 2025 is 45. So we now add all the side lengths together. The equation is 45+45+45+45. This makes 180m. It takes 180m of fence.
Hope this helps. Please consider making me the Brainliest, it’s not necessary but it is appreciated as I put time and research into each answer. Have a great day, stay safe and stay healthy.
