Now imagine that instead of walking along the path 1→2→3→4→1, ann walks 80 meters on a straight line 33∘ north of east starting

stealth61 [152]

Answer:

Anna's walk as a vector representation is $80\cos 33^{\circ}\hat{i}+80 \sin33^{\circ}\hat{j}$ and refer attachment.

Step-by-step explanation:

Let the origin be the point 1 from where Ann start walking.

Ann walks 80 meters on a straight line 33° north of the east starting at point 1 as shown in figure below,

Resolving into the vectors, the vertical component will be 80Sin33° and Horizontal component will be 80Cos33° as shown in figure (2)

Ann walk as a vector representation is $80\cos 33^{\circ}\hat{i}+80 \sin33^{\circ}\hat{j}$

Thus, Anna's walk as a vector representation is $80\cos 33^{\circ}\hat{i}+80 \sin33^{\circ}\hat{j}$

The Zonda Information and Telephone Company (ZI&T) calculates a customer’s total monthly cell phone

Olenka [21]

Answer:

The answer of the following question is m = \frac{C - b - bt}{r + rt}.

Solution:

C = (b + rm)(1 + t),

C = b + rm + bt + rmt

C = b + bt + rm + rmt

C - b - bt = m (r + rt)

\frac{C - b - bt}{r + rt} = m

t\neq -1,

r\neq 0

The meat department of a supermarket sells ground beef in approximate 1 lb packages, but there is some variability. A random sam

grin007 [14]

Answer:

1.05 ± 0.05 lbs

Step-by-step explanation:

Hi!

We can calculate this interval with the z-score of the 90% which is (by convention) 1.645

The interval is calculated as follows:

$x_m \pm 1.654(\frac{\sigma}{\sqrt n})$

where x_m is the mean, σ the standar deviation and n is the number of samples:

replacing these values we get:

$1.05 \pm (1.645 \times \frac{0.23}{\sqrt 65})\\1.05 \pm 0.046$

*rounded to the first decimal*

1.05 ± 0.05

Answer:

<em>Question 1) </em>

The graph of $y=\dfrac{2}{x}$ is attached to the answer.

The graph of such a functio lies in first and third quandrant such that the graph tends to 0 when x→∞ or when x→-∞ and graph tends to ∞ when x→0.

We can also show the values of this equation on a table:

<u> x-values</u> <u> y-values</u>

1/2 4

1 2

2 1

3 2/3

<em>Question 2)</em>

The graph of the equation $y=x^{2}+2x-3$ is attached to the answer.

we will get a upward parabola with this equation whose vetex is: (-1,-4).

The ordered pair on the graph could be shown with the help of a table:

Rosa is converting a unit of measure in one system to a unit of measure in another system. 1,760 yd1 mi⋅0.914 m1 yd⋅1 km1,000 m

kodGreya [7K]

Answer: Rosa is finding the number of kilometers in a mile.

Step-by-step explanation:

According to the given information, we have:

1,760 yd=1 mi

0.914 m=1 yd

1 km=1,000 m

So, as we can see, Rosa wants to convert miles to yards, then yards to meters and finally meters to kilometers:

$(1 mi\frac{1,760 yd}{1 mi})( \frac{0.914 m}{1 yd})( \frac{1 km}{1,000 m})=1.608 km$

Then:

$1 mi=1.608 km$ This is the number of kilometers in a mile.
