Hi! 

This problem seems to be asking us to solve a proportion. In order to do that, we need to cross multiply. 

All percentages are out of 100, so what we need to do is make \frac{700}{2000} into a ratio out of 100 by cross multiplying.

\frac{x}{100} × \frac{700}{2000}

First, multiply 700 by 100

700 × 100 = 70,000

Next, divide that 70,000 by 2,000 

70,000 ÷ 2,000 = 35

Final answer: The slice of cake takes up 35% of Jone's daily calorie goal

let t : r2 →r2 be the linear transformation that reflects vectors over the y−axis. a) geometrically (that is without computing a
tangare [24]

(a) ( 1, 0 ) is the eigen vector for '-1' and ( 0, 1 ) is the eigen vector for '1'.

(b)  two eigen values of 'k' = 1, -1

for k = 1, eigen vector is \left[\begin{array}{c}0\\1\end{array}\right]

for k = -1 eigen vector is \left[\begin{array}{c}1\\0\end{array}\right]

See the figure for the graph:

(a) for any (x, y) ∈ R² the reflection of (x, y) over the y - axis is ( -x, y )

∴ x → -x hence '-1' is the eigen value.

∴ y → y hence '1' is the eigen value.

also, ( 1, 0 ) → -1 ( 1, 0 ) so ( 1, 0 ) is the eigen vector for '-1'.

( 0, 1 ) → 1 ( 0, 1 ) so ( 0, 1 ) is the eigen vector for '1'.

(b) ∵ T(x, y) = (-x, y)

T(x) = -x = (-1)(x) + 0(y)

T(y) =  y = 0(x) + 1(y)

Matrix Representation of T = \left[\begin{array}{cc}-1&0\\0&1\end{array}\right]

now, eigen value of 'T'

T - kI =  \left[\begin{array}{cc}-1-k&0\\0&1-k\end{array}\right]

after solving the determinant,

we get two eigen values of 'k' = 1, -1

for k = 1, eigen vector is \left[\begin{array}{c}0\\1\end{array}\right]

for k = -1 eigen vector is \left[\begin{array}{c}1\\0\end{array}\right]

Hence,

(a) ( 1, 0 ) is the eigen vector for '-1' and ( 0, 1 ) is the eigen vector for '1'.

(b)  two eigen values of 'k' = 1, -1

for k = 1, eigen vector is \left[\begin{array}{c}0\\1\end{array}\right]

for k = -1 eigen vector is \left[\begin{array}{c}1\\0\end{array}\right]

Answer:

Step-by-step explanation:

Least to largest:

First compare the whole parts of the decimal number. The whole part with greater number will be the greatest number.

2) Then compare the decimal parts. Compare tenth place. The decimal number that has greater number in the tenth place will be greater.

3) If the number in  tenth place is equal, then compare 100th place and so on

A) 15.99  ; 16  ; 16.02  ; 16.2

B) 4.45  ; 4.9945  ; 5.545   ; 5.56

c) 44.11  ; 44.5  ; 45 ; 45.01

D) 8.995 ;   9.0599  ;  9.27  ;  9.6

Greatest to least

A) 2.111   ; 2.11   ; 2.1   ; 2.01

B) 32.32  ; 32.302     ; 32.032  ; 3.99
