Answer:
Step-by-step explanation:
From the problem, we deduct that the function has to be quadratic, because it's mention two zeros, which is proper of a polynomial expression with grade 2.
So, we can say that:
Because, 5 and 0 are roots of the expression.
Also, we know that the point is on the curve, this means:
Replacing this relation in the first expression, we have:
So, the expression would be:
If we graph, we could get the vertex easier.
You can see in the image, that the vertex is at x = 2.5
Therefore, the option C is the answer.
However, the first option has this function:
h(x) = –0.25(x)(x – 5).
Which also can be solution, because, if we try x = 4:
h(4) = –0.25(4)(4 – 5)=1
Therefore, option A is also part of the answer.
Answer
answer A and C are right
14.6 feet long would the cloth have to be so that the opening of the tent was 6 feet high and 8 feet wide.
Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
To find the length of the cloth needed to make the tent, we can use the Pythagorean theorem.
The triangle formed by the tent is isosceles, the hypotenuse is equal to one of the equal sides, and we can use the Pythagorean theorem to solve for "x".
The length of the hypotenuse is:
√(1/2× 8)² + 6² )
√16 + 36 )
√52= 2√13
Since the tent is isosceles, the length of each of the two equal sides of the triangle is also "x", so we have:
2x = 2√13
Solving for "x", we get:
x = √13
Therefore, the length of the cloth needed to make the tent is:
2x + 8
= 2√13 + 8
= 14.61 feet
So the cloth would have to be 14.61 feet long.
Hence, 14.6 feet long would the cloth have to be so that the opening of the tent was 6 feet high and 8 feet wide.
