Answer:

Step-by-step explanation:

There is a SUBTRACTION symbol in the problem. So, you will do the opposite, & ADD the 2 available numbers in the equation. 10+7=17

When you replace that y with 17, the equation is correct.

Assume that lines that appear to be tangent are tangent. O is the center of the circle. Find the value of x.

MariettaO [177]

Draw an imaginary line from the vertex of angle x to the center of the circle.
This divides the 4-sided polygon into two right triangles. For example, the upper right triangle has an acute angle whose measure is 135 degrees / 2, or 67.5 degrees, and the another acute angle whose measure is x/2.

x/2 and 67.5 degrees are complementary angles, so x/2 + 67.5 deg = 90 deg. Thus, x/2 = 22.5 deg, and so x = 45 deg. (answer)

Answer:

a) See attachment 1.

b) t² and D

c) See attachment 2.

d) g = 9.8 m/s² (1 d.p.)

Step-by-step explanation:

See attachment 1. The line of best fit is shown in red.

The quantities the student should graph in order to produce a <u>linear relationship</u> between the two quantities are t² and D.

Make a table of values of t² and D:

$\begin{array}{|l|l|l|l|l|l|}\cline{1-6} \rm t^2& 0.0196& 0.1024& 0.2116 & 0.3481& 0.3969\\\cline{1-6} \rm D & 0.10 & 0.50& 1.00 & 1.70 & 2.00\\\cline{1-6}\end{array}$

<u>Plot</u> a graph of D against t² and draw a line of best fit (see attachment 2).

From inspection of the graph, the line of best fit passes through the origin (0, 0) and (0.1024, 5.0). Therefore, use these two points to find the slope of the line:

$\textsf{slope}\:(m)=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{0.5-0}{0.1024-0}=4.8828125...\:\rm m/s^2$

Therefore:

$\rm \implies \dfrac{1}{2}g=4.8828125...\:\rm m/s^2$

$\rm \implies g=2 \cdot 4.8828125...\:\rm m/s^2$

$\rm \implies g=9.8\:\rm m/s^2\:(1\:d.p.)$

Answer:

A. 14.7cm

Step-by-step explanation:

In Triangle ABC

$\angle A=60^\circ\\\angle B=45^\circ\\b=12cm$

We are to determine the measure of side a.

Using Law of Sines

$\dfrac{a}{\sin A}= \dfrac{b}{\sin B}\\\dfrac{a}{\sin 60^\circ}= \dfrac{12}{\sin 45^\circ}\\\\$Cross multiply\\a*sin 45^\circ=12*\sin 60^\circ\\$Divide both sides by sin 45^\circ\\\dfrac{a*sin 45^\circ}{sin 45^\circ}= \dfrac{12*\sin 60^\circ}{\sin 45^\circ}\\\\a=14.7$ cm (to the nearest tenth of a cm)$
