Mathematics

Reptile [31]3 years ago

Answer:

Option (2)

Step-by-step explanation:

Let the equation of the parabola represented by the curve in the graph is,

y = a(x - h)² + k

Where (h, k) is the vertex of the parabola and 'a' is the coefficients of highest degree term of the parabola.

From the graph,

Vertex of the parabola is (-3, 0) and a point (-13, -5) exactly lies on the curve.

vertex form of the parabola will be,

y = a(x + 3)² + 0

y = a(x + 3)²

Since (-13, -5) lies on this graph,

-5 = a(-13 + 3)²

-5 = 100a

a = -\frac{5}{100}

a = -\frac{1}{20}

So the equation of the parabola will be,

y=-\frac{1}{20}(x+3)^2

Option (2) will be the answer.

Calculate the length of a minor arc OP in terms of π​
Tanzania [10]

Answer:

arc length = radius * angle in degrees * (PI / 180)

arc length = 6 * 160 * (PI/180)

arc length = PI * 960 / 180

arc length = PI * 5 + (60/180)

arc length = (16/3) * PI

Henry has 20 Lawns mowed out of a total of 50 lawns. What percentage of the lawns does Henry have to still mow?
elena55 [62]
Henry has completed 40% of his work, leaving him with a remaining 60%.

What you do is divide 20 by 50 and your answer is .4, move the decimal two places to the right to get your percent, 40. Then subtract it out of 100 and you get the remaining 60%, which essentially is your answer.

Answer:

so to get a third you divide it by 3

first convert it to fraction

so it is 26/3

so do 26/3 divided by 3

so we do keep switch flip

26/3*1/3

so answer is 26/9 or 2 8/9

Lance says that you can compare any decimal numbers the way that you alphatbetize words you can tell which number is first by co
Afina-wow [57]

Answer:

No, Lance's thinking is wrong because you cannot compare decimal numbers with alphabetizing words. For example, if we compare 37.6 to 7.42 using the method of Lance, we would probably say 37.6 is less than 7.42 because 3 is less than 7. But it is wrong. The 3 in 37.6 is in the tens place. On the other hand, 7.42 contains no tense. Therefore, 37.6 is actually higher.
