Answer:

1,Let us suppose that the height of the ladder is h and the horizontal distance of the ladder from the wall is d, then we use these two important trigonometric functions; the sine and the cosine.

h = sin 78 * 8 m and d = cos 78 * 8m where sin 78 = 0.9781 and cos 78 = 0.2079

With the given values, I expect you to do the two multiplications yourself. You will obtain a near to 8 m answer for the height h and a near to 1.7 m answer for the distance d.

2, The ship is 15 km from the port.

3,30m The ship must travel 15.6km 10 km 8. A rectangular field is 40 m long and 30 m wide. Carl walks from one corner of the field to the opposite corner along the edge of the field. Jade walks across the field diagonally to arrive at the same corner. Tip How much shorter is Jade's shortcut? Show your work. Sketch a diagram Carl-40m ade - b?= C² first. 40m. Jade = a't 62=(3 30' + 402 c 900 + 1,600 e? C² =2,5 U0 %3D C=/2500 C=50 10m shorter. jade shortcut is 172

Emma wants to buy a new cell phone. She commits to saving 10% of the cost

julia-pushkina [17]

Answer:

p(m) = 0.1(m)

Step-by-step explanation:

Given that :

Percentage of cost saved per month = 10%

The percentage, p of cost saved after m months will be ;

Percentage of cost saved after m, months will be ; p(m) = Percentage of cost saved per month * number of months

p(m) = 10% * m

p(m) = 0.1(m)

The ordered pairs (1,1),(2,4),(3,9),(4.16) and (5,25) represent a function what is a rule that represents this function

galina1969 [7]

For each of the ordered pairs, the x coordinate is squared to find y.

x = 1
1^2 = 1

x = 2
2^2 = 4

x = 3
3^2 = 9

x = 4
4^2 = 16

Which ordered pair is the solution to the system of equations?

ryzh [129]

Answer:

(3, 3)

Step-by-step explanation:

The solution of such a system is the ordered pair that is a solution to both equations. To solve a system of linear equations graphically we graph both equations in the same coordinate system. The solution to the system will be in the point where the two lines intersect.

A sports club rewards teams based on overall points earned in a season. The data for points are shown in the table, where Low re

Sholpan [36]

Given the table below where Low represents the fewest points scored and High represents the highest points scored by a single team member.

$\begin{center}
\begin{tabular}
{|c||c|c|c|c|c|c|c|}
Team & Low & High & Range & Mean & Median & IQR & \sigma \\ [1ex]
Team A & 22 & 58 & 36 & 42.1 & 44 & 18.25 & 10.35 \\ 
Team B & 38 & 49 & 11 & 43.9 & 44.5 & 3.5 & 2.97 \\ 
Team C & 27 & 36 & 9 & 31.8 & 32 & 3.75 & 2.55
\end{tabular}
\end{center}$

PART A:
The range, the IQR (inter-quartile range) and the standard deviations are measures which are used to measure the spread of a data set.

A dataset is more consistent relative to another data set when the standard deviation is less than that of the other data set.

From the table, it can be seen that Team C has the least standard deviation.

Therefore, If the club wants to award the team that has the most consistent scoring among its team members, team C should be chosen.

PART B
The mean and the median is a measure of center of a data set.
The mean describes the average of a data set.

From the table, it can be seen that Team B has the highest average score.

Therefore, If the club wants to award the team with the highest average score, team B should be chosen.
