The equation of a straight line is given by:

y = mx + c

where m is the slope and c is the y-intercept.

From the given graph, the y-intercept is 1.

The slope of a straight line is given by:

m= \frac{y_2-y_1}{x_2-x_1}

Where (x_1,y_1) and (x_2,y_2) are two points on the line.

From the graph, (0, 1) and (14, 8) are two points on the line, thus:

m= \frac{8-1}{14-0} = \frac{7}{14} = \frac{1}{2}

Therefore, the equation representing the graph is y= \frac{1}{2} x+1

The triangles are similar, find the length of the unknown side. Round your answers to the nearest tenth (0.1), if necessary.
Doss [256]

Answer:

22

Step-by-step explanation:

Similar shapes must have corresponding sides in a constant proportion. Therefore, we can set up the following equation and solve for ?:

\frac{28}{42}=\frac{?}{33} (divide corresponding sides)

\frac{28}{42}=\frac{?}{33},\\\\?=\frac{28\cdot 33}{42}=\boxed{22}

You stand 50 feet from a monument. The angle of depression from the top of the monument to your feet is 64 degrees. Approximatel
Murrr4er [49]

Answer:

The monument is approximately 86.6 feet tall

Step-by-step explanation:

The given monument parameters are;

The distance of the person from the monument = 50 feet

The angle of depression from the top of the monument to the person's feet = 64°

Given that the angle of elevation to the top of the monument from the person's feet = The angle of depression from the top of the monument to the person's feet, we have;

tan(Angle of depression) = tan(Angle of elevation) = (The height of the monument)/(The distance from the monument)

∴ The height of the monument = tan(Angle of depression) × The distance from the monument

Substituting the known values, gives;

The height of the monument = tan(60°) × 50 ≈ 86.6

The height of the monument ≈ 86.6 feet.

A fair coin is flipped 120 times. Estimate the expected number of ‘heads’.
Bumek [7]

when coin is flipped 5 times probability is 1/2

so coin heads comes out to be 2.5

This is a binomial distribution with a probability of success = 0.5 (fair coin).

n=10

so

mean = E[x] = np =10*0.5 =5
