Find the equation, (f(x) = a(x-h)2+ k), for a parabola containing point (-1,0) and having (-3, 4) as a vertex. What is the standard form of the equation?

Answers

Answer 1
Let's begin with  f(x) = a(x-h)^2+ k.  Note that we must use "^" to indicate exponentiation.  Write (x-h)^2, not (x-h)2.

If (-3,4) is the vertex, then the above equation becomes f(x) = a(x-[-3])^2 + 4, or 

f(x) = a(x+3)^2 + 4.  We are told that the graph passes through (-1,0), so must now substitute those coordinates into the above equation:

f(-1) = a([-1]+3)^2 + 4 = 0 (0 is the value of f when x is -1)

Then we have a(2)^2 + 4 =0, or 4a + 4 = 0.  Thus, a = -1.

The equation of this parabola is now f(x) = -(x+3)^2 + 4.

Write it in "standard form:"  f(x) = -(x^2 + 6x + 9) + 4, or 
                                           f(x)  = -x^2 - 6x - 9 + 4, or
       answer =>                   f(x) = -x^2 - 6x - 5 = ax^2 + bx + c

Thus, a=-1, b=-6 and c= -5.
Answer 2

Answer:

D.The vertex form is f(x) = −(x +3)^2 + 4. The standard form is f(x) = −x2−6x−5.

Evaluate the integral. 2 (6t i − t3 j + 2t3 k) dt 0

Answers

Final answer:

The integral of the vector field 2 (6t i − t3 j + 2t3 k) from 0 to t can be broken down into three separate integrals for each component, yielding the resulting integral vector of (6t^2)i - (0.5t^4)j + (t^4)k.

Explanation:

The integral you're asking about is a vector field integral, which comes up primarily in physics-related problems. The integral of a vector field, in this case, 2 (6t i − t3 j + 2t3 k) with respect to time, can be broken down into three separate integrals, each corresponding to a different component.

To solve, you would perform each integral separately:

Integral from 0 to t of 2*6t dt = 6t^2 between 0 and t = 6t^2 Integral from 0 to t of 2*-t^3 dt = -0.5*t^4 between 0 and t = -0.5t^4 Integral from 0 to t of 2*2t^3 dt = t^4 between 0 and t = t^4

Combine these answers to yield the integral vector (6t^2)i - (0.5t^4)j + (t^4)k as the solution. Please remember to always check your calculations to ensure accuracy!

volume=length times width times height
her current suitcase volume is 28*16*8=3584 cubic inches

her new one will have each dimention mulipled by 1 and 1/2 or 1.5

well the line that bisects RS, will cut RS in two equal halves, therefore, that line will cut RS perpendicularly at the midpoint of RS.

now, what the dickens is the midpoint of RS anyway?

Final answer:

The equation of the perpendicular bisector of the segment with endpoints R(-1,6) and S(5,5) is found by calculating the midpoint, slope, and using the negative reciprocal for the perpendicular slope. It is then written in point-slope form and converted to standard form, resulting in 12x - 2y = 13.

Explanation:

To find the equation of a line that is the perpendicular bisector of a segment with endpoints R(-1,6) and S(5,5), we need to take the following steps:

Determine the midpoint of the segment RS which will be a point on our bisector.Calculate the slope of the line segment RS.Find the negative reciprocal of the slope from step 2, which will give us the slope of our perpendicular bisector.Write the equation of the bisector line using the point-slope form and then convert it into standard form.

The midpoint of RS is given by ((-1+5)/2, (6+5)/2) = (2, 5.5). The slope of RS is (5-6)/(5-(-1)) = -1/6. The negative reciprocal of -1/6 is 6. Thus, the slope of our bisector is 6.

Using the point-slope form with the midpoint, y - 5.5 = 6(x - 2). Expanding and rearranging to standard form, we get:

6x - y = 12 - 5.5 -> 6x - y = 6.5.

Multiplying through by 2 (to clear the decimal), we obtain:

12x - 2y = 13, which is the standard form equation of the perpendicular bisector of segment RS.

A restaurant uses 8 1/4 pounds of carrots to make 6 carrot cakes. Frank wants to use the same recipe. How many pounds of carrots does Frank need to make one carrot cake?

Answers

1.375 lbs of carrots

Frank needs [tex]\( \frac{11}{8} \)[/tex] pounds of carrots to make one carrot cake.

To find out how many pounds of carrots Frank needs to make one carrot cake, we first need to determine how many pounds of carrots are used per carrot cake in the original recipe.

Given that the restaurant uses 8(1)/(4) pounds of carrots to make 6 carrot cakes, we divide the total pounds of carrots by the number of cakes to find the amount per cake.

[tex]\( \text{Carrots per cake} = \frac{8\frac{1}{4}}{6} \)[/tex]

First, we convert the mixed number [tex]\(8\frac{1}{4}\)[/tex] to an improper fraction:

[tex]\(8\frac{1}{4} = \frac{(8 \times 4) + 1}{4} = \frac{33}{4}\)[/tex]

Then, divide by 6:

[tex]\( \frac{33}{4} \div 6 = \frac{33}{4} \times \frac{1}{6} = \frac{33}{24} = \frac{11}{8} \)[/tex]

So, Frank needs [tex]\( \frac{11}{8} \)[/tex] pounds of carrots to make one carrot cake.

Standard form of 210 million, 64 thousands, and fifty

Answers

Your answer would be 210,640,050.

The standard form of 210 million, 64 thousands, and fifty is 210,064,050. This is found by adding the values of each place: 210,000,000 for million, 64,000 for thousand, and 50 for the units.

The standard form of a number is a way of writing numbers that is commonly used in mathematics, especially in arithmetic and place value studies. To write the number 210 million, 64 thousands, and fifty in standard form, one combines these values considering their place values.

The value of 210 million is simply 210,000,000. The value of 64 thousands is 64,000, and the value of fifty is 50. When these are combined, we get:

210,000,000 (Two hundred and ten million)+ 64,000 (Sixty-four thousand)+ 50 (Fifty)

Adding these together:

210,000,000 + 64,000 + 50 = 210,064,050

Therefore, the standard form of 210 million, 64 thousands, and fifty is 210,064,050.
