The altitude of the hill whose top rises 64 feet above checkpoint -213, is 277 feet above sea level.

The altitude refers to the vertical distance or height of an object or point in relation to sea level (true altitude) or ground level (absolute altitude).

The altitude of a hill refers to its height measured from the ground level or the sea level, as the case may be.

In this situation, we can compute the altitude of the hill as the difference between the rise of the hill or mountain above the checkpoint and the given checkpoint.

The rise of the top of a hill = 64 feet

Given checkpoint = -213

The altitude of the hill = 277 feet [64 - (-213)]

Thus, the position or altitude of the hilltop in relation to the ground or sea level is 277 feet.

Problem 1

--------------------------------

Explanation:

The x intercepts are -1 and 3, meaning that (x+1) and (x-3) are factors.

This is because x = -1 leads to x+1 = 0 when you add 1 to both sides. And x = 3 leads to x-3 = 0 when you subtract 3 from both sides.

The quadratic equation would be y = a(x+1)(x-3) = a(x^2-2x-3) for some constant 'a'. Use the point (x,y) = (1,-8) to find the value of 'a'.

y = a(x^2-2x-3)

-8 = a(1^2-2*1-3)

-8 = a(-4)

-4a = -8

a = -8/(-4)

a = 2

Therefore,

y = a(x^2-2x-3)

y = 2(x^2-2x-3)

y = 2x^2-4x-6

======================================================

Problem 2

--------------------------------

Explanation:

We'll follow the same idea as the previous problem.

The factors are (x-0) and (x-1). This is the same as saying the factors are x and (x-1)

So we have y = ax(x-1) = a(x^2-x)

Plug in (x,y) = (2,-2) and solve for 'a'.

y = a(x^2-x)

-2 = a(2^2-2)

-2 = a(2)

2a = -2

a = -2/2

a = -1

The equation updates to

y = a(x^2-x)

y = -1(x^2-x)

y = -x^2+x

Answer:  1) y = 2(x + 1)(x - 3)

               2) y = -(x)(x - 1)

Step-by-step explanation:

Use the Intercept form of a quadratic equation: y = a(x - p)(x - q) where

1) p = -1, q = 3, (x, y) = (1, -8)

y = a(x + 1)(x - 3)

-8 = a(1 + 1)(1 - 3)

-8 = a(2)(-2)

-8 = -4a

2 = a

Equation: y = 2(x + 1)(x - 3)

2) p = 0, q = 1, (x, y) = (2, -2)

y = a(x - 0)(x - 1)

-2 = a(2 - 0)(2 - 1)

-2 = a(2)(1)

-2 = 2a

-1 = a

Equation: y = -(x)(x - 1)

The height of the rice cylinder is 12in.

The volume of the flour cylinder is 50.24 in.

A cylinder is a 3-D figure that has a radius and a height.

The volume of a cylinder is given as πr²h.

Example:

The volume of a cup with a height of 5 cm and a radius of 2 cm is

Volume.

= 3.14 x 2 x 2 x 5

= 62.8 cm³

We have,

Sugar cylinder:

radius = 2.5 in

height = 8 in

Volume.

= πr²h

= 3.14 x 2.5 x 2.5 x 8

= 157 in²

Rice cylinder:

radius = 2.5 in

height = h

Volume = πr²h

Volume = 235.5 in²

πr²h = 235.5

3.14 x 2.5 x 2.5 x h = 235.5

196.26 x h = 235.5

h = 12 in

Flour cylinder:

Area of base = 12.56 in²

height = 4 in

Volume = x

Area of base = πr²

12.56 = 3.14 x r²

r² = 12.56/3.14

r² = 4

r = 2

Now,

Volume.

= πr²h

= 3.14 x 2 x 2 x 4

= 50.24 in²

Thus,

Answer:

  40 units²

Step-by-step explanation:

You can figure the side lengths using the distance formula, or you can use a formula for finding area from coordinates. The latter looks like ...

  \(\displaystyle A=\dfrac{1}{2}\left|\sum\limits_{k=1}^n{x_k(y_{k-1}-y_{k+1})}\right|\qquad\text{where $y_0=y_n$ and $y_{n+1}=y_1$}\)

So, the area is ...

  A = (1/2)|(-6(-5-1) +2(-1-7) +2(1-3) +3(7+3) +3(3+5) -5(-3+1)|

  = (1/2)|36 -16 -4 +30 +24 +10| = (1/2)(80)

 A = 40

The area of the figure is 40 units².

The measure of side KL from triangle KLM is 22 units.

The results of operations between vectors are, respectively:

Case A: u + w = <- 3, - 1>

Case B: - 6 · v = <6, 6>

Case C: 3 · v - 6 · w = <- 21, - 15>

Case D: 4 · w + 3 · v - 5 · u = <39, 4>

Case E: |w - v| = √(4² + 3²) = 5

In this problem we must determine the operations between vectors, this can be done by following definitions:

Vector addition

v + u = (x, y) + (x', y') = (x + x', y + y')

Scalar multiplication

α · v = α · (x, y) = (α · x, α · y)

Norm of a vector

|u| = √(x² + y²)

Now we proceed to determine the result of each operation:

Case A:

u + w = <- 6, - 3> + <3, 2>

u + w = <- 3, - 1>

Case B:

- 6 · v = - 6 · <- 1, - 1>

- 6 · v = <6, 6>

Case C:

3 · v - 6 · w = 3 · <- 1, - 1> - 6 · <3, 2>

3 · v - 6 · w = <- 3, - 3> + <- 18, - 12>

3 · v - 6 · w = <- 21, - 15>

Case D:

4 · w + 3 · v - 5 · u = 4 · <3, - 2> + 3 · <- 1, - 1> - 5 · <- 6, - 3>

4 · w + 3 · v - 5 · u = <12, - 8> + <- 3, - 3> + <30, 15>

4 · w + 3 · v - 5 · u = <39, 4>

Case E:

|w - v| = |<3, 2> - <- 1, - 1>|

Answer:

Step-by-step explanation:

Choosing the correct answer here is not the same as knowing what the correct value is.

You know that √30 < √100 = 10, so the sum must be negative. That is, 10 subtracted from a positive number less than 10 will give a negative result.

You know that 25 < 30 < 36, so √25 < √30 <√36. That is, √30 will be between 5 and 6. If we say √30 ≈ 5.5, then the sum is ...

We can break it into two parts.

-> First, the rectangle on the bottom is made up of 2 feet x 16 feet. The formula for area of a rectangle is length times width, so in this case it is equal to 32 feet

-> Next, the triangle has sides of 10 feet, 10 feet, and 16 feet. We can calculate that the height is 6. The formula for area of a triangle is base times height divided by two, so, \(\frac{16*6}{2}= \frac{96}{2} =\) 48 feet

-> Last, we can add the two totals together. 32 feet + 48 feet = 80 feet giving us our final answer of 80 feet². As this answer is not pictured I am going to assume they are not including Heron's formula or other more complex formulas, leading us to the answer of "can't be determined"

The domain and range of a linear function is always real numbers (T or F)

It is True. This is because of a couple of reasons.

    1.) You cannot divide by 0.

     2. A negative number cannot have its square root taken.

The range is determined by the domain in a linear function, and thus it must always consist of real numbers.

Answer:

The rates are not equivalent since Maria saves $0.50 more per month than Ralph.

Step-by-step explanation:

We can determine if two rates are equivalent by comparing the rates at which they save per month.

Maria's savings per month:

Both 50 and 4 can be divided by 2, which gives us 25/2.  As a regular number, this becomes 12.5/1 which means Maria saves $12.5 per month.

Ralph's savings per month:

Both 60 and 5 can be divided by 5, which gives us 12.  Thus, Ralph saves $12 per month.

Thus, the rates are not equivalent as Maria saves $0.50 more per month than Ralph.

Answer:

t = 6.8 years

Step-by-step explanation:

The formula for compound interest is

\(A(t)=P(1+r/n)^n^t\), where P is the principal/amount invested, r is the interest rate, n is the number of compound periods per year (4 for quarterly), and t in the time in years.

We know that A = $5900, P = $4000, and r = 0.0575 (we must convert the percentage to a decimal).  We must solve for t and round to the nearest tenth:

\(5900=4000(1+0.0575/4)^(^4^t^)\\\\59/40=(1623/1600)^4^t\\\\log(59/40)=log(1623/1600^4^t)\\\\log(59/40)=4t*log(1623/1600)\\\\log(59/40)/log(1623/1600)=4t\\\\1/4(log(59/40)/log(1623/1600))=t\\\\6.80773607=t\\\\6.8=t\)

The required value of 4/ 27 to tenth decimal places is 0.1.

To determine the 4/ 27 to the tenth decimal place.

Decimals is defined as one of the digits, which has a number and the fractional part separated by a decimal point after the whole number.

Recurring Decimal is defined as also named repeating decimal, is a decimal number that only consists of repeating digits after a certain interval after the decimal. For example, 94.642642642..., 213.569569... etc.

Here,
= 4 / 27
dividing 4 by 27
4/27 = 0.148148148148148
now round of the above digit to tenth decimal place means place after the decimal is tenth place. So,
= 0.1

Thus, the required value of 4/ 27 to tenth decimal place is 0.1.
