Find the value of X! Plz help, timed quiz!
Soloha48 [4]

Answer:

14) x=30

because 30 times 2 is 60

15) x=30

180-120=60

60/2=30

16)  x= 36

because 180- 146 is 34

34+2= 36

hope this helps!

Matrix a is a 6 × 5 matrix. which order of matrix can be multiplied by matrix a to create matrix ab?
mezya [45]

Order (B) 5 × 6 of the matrix can be multiplied by matrix a to create matrix ab.

<h3>What is a matrix?</h3>
  • A matrix is a rectangular array or table of numbers, symbols, or expressions that are organized in rows and columns to represent a mathematical object or an attribute of such an object in mathematics.
  • For instance, consider a matrix with two rows and three columns.

To find the order of matrix:

  • We must first check the dimension of two matrices, say matrix A by matrix B, before we may multiply them.
  • Multiplication is achievable if the number of columns in the first matrix, A, equals the number of rows in the second matrix.
  • Dimension is assigned to the provided matrix: 6 × 5
  • This means the given matrix contains six rows and five columns.
  • As a result, the second matrix MUST have 5 rows in order for multiplication to be POSSIBLE.
  • The only matrix with 5 rows among the above alternatives is the matrix with dimension (B) 5 × 6.

To prove:

  • In other words, the inner products of the dimensions should be equal.
  • That is; (a × b)(b × a) is possible but (a ×b)(c × b) is impossible.
  • The dimensions of the matrix are given by, row × column.

Therefore, order (B) 5 × 6 of the matrix can be multiplied by matrix a to create matrix ab.

AfilCa [17]

Answer:

h(x)=2(x + 3)^{\frac{1}{2} }

Step-by-step explanation:

Parent function of the square root function has been given as,

f(x) = x^{\frac{1}{2} }

If the graph of the given function is stretched vertically by the scale factor = g(x) = k(x^\frac{1}{2})

If the graph is shifted 3 units to the left,

h(x) = k(x + 3)^{\frac{1}{2} }

Since, the graph of the function passes through a point (-2, 2),

2=k(-2 + 3)^\frac{1}{2}

2 = k

Therefore, the function is h(x)=2(x + 3)^{\frac{1}{2} }.

A 25 foot ladder is leaning against a tree. If the base of the ladder is 6 feet
Vera_Pavlovna [14]

9514 1404 393

Answer:

  24.3 ft

Step-by-step explanation:

If h is the height of the ladder up the tree, the geometry can be modeled as a right triangle with legs h and 6, and hypotenuse 25. The Pythagorean theorem gives you the relation ...

  h² +6² = 25²

  h² = 625 -36 = 589

  h = √589 ≈ 24.3

The ladder reaches about 24.3 feet up the tree.
