Mathematics
1 answer:
kaheart [24]3 years ago
4 0

Answer:

domain:

( -  \infty , \infty )

range:

( -  \infty ,4]

equation:

y =  - 2(x - 3) {}^{2}  + 4

Step-by-step explanation:

domain is all X values and the X values will extent till infinity in both negative and positive direction, the range is all y values and the y value will go from negative infinity all the way to 4, where the graph stops.

The parallelogram shown below has an area of 24 units2.
Ber [7]

Answer:

9

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

Explanation:

The area of the parallelogram is equal to the base times height. The formula to use is A = b*h. The height and base are always perpendicular to one another.

The base is some unknown variable b. Multiply the base by the height 15 to get 15*b which is equal to the area 135

Therefore, 15*b = 135

Divide both sides by 15 and we isolate b

15b = 135

15b/15 = 135/15

b = 9

So the base is 9

Check:

area = base*height = 9*15 = 135

so the answer is confirmed

side note: we never use the value 17 at all. It is likely put in there as a distraction.

Write the reciprocal of<br> a) 7/10<br> b)3.5
Thepotemich [5.8K]

Answer:

a)

\frac{10}{7}

b)

\frac{10}{35}

Step-by-step explanation:

The reciprocal of a number is the inverse of the number

\frac{7}{10}  =  \frac{10}{7} (reciprocal)

3.5 \: is \: also \:  \frac{35}{10}

\frac{35}{10}  =  \frac{10}{35} (reciprocal)

you \: may \: choose \: to \: simplify \: to \: the \: lowest \: term \: depending \: on \: the \: question

Determine if the described set is a subspace. Assume a, b, and c are real numbers. The subset of R3 consisting of vectors of the
Arte-miy333 [17]

This question is incomplete, the complete question is;

Determine if the described set is a subspace. Assume a, b, and c are real numbers.

The subset of R³ consisting of vectors of the form \left[\begin{array}{ccc}a\\b\\c\end{array}\right] , where abc = 0

  • The set is a subspace
  • The set is not a subspace

Answer:

Therefore; The set is not a subspace

Step-by-step explanation:

Given the data the question;

the subset R³;

S = {  \left[\begin{array}{ccc}a\\b\\c\end{array}\right] , where abc = 0 }

we know that a subset of R³ is a subspace if it stratifies the following properties;

  1. it contains additive identity
  2. it is closed under addition
  3. it is closed under scales multiplication

Looking at the properties, we can say that it is not a subspace

As;

         u = \left[\begin{array}{ccc}1\\1\\0\end{array}\right] ∈ S       and v = \left[\begin{array}{ccc}0\\1\\1\end{array}\right]  ∈ S

As    1×1×0=0                          0×1×1=0

But   u+v = \left[\begin{array}{ccc}1+0\\1+1\\0+1\end{array}\right] = \left[\begin{array}{ccc}1\\2\\1\end{array}\right]  ∉  S     as 1×2×1 ≠ 0

Hence, it is not closed under addition.

Therefore; The set is not a subspace
