Answer:

Slope: $-\frac{3}{4}$

Y intercept: 7

Equation: $y=-\frac{3}{4}x+7$

Step-by-step explanation:

The slope is found by doing the equation $\frac{rise}{run}$ . When looking at the first two points, it's shown that the rise (difference between the two y values) is -3 (since it decreased by 3) and the run (difference between the two x values) is 4 (since it increased by 4).

This gives us a slope of $-\frac{3}{4}$ .

The y intercept is found by looking at the y value when x = 0. In this picture, it is clear that it is 7.

The equation you want to use is y = mx + b , where b is the y intercept and m is the slope. Just plug in the numbers and you got your equation!

Please helpp<br> What is the area of the purple region? <br> What is the area of the green region?

butalik [34]

what do we need to know:

the radius of the semi circles;

the area of:

purple region = area of a circle = pi * r^2;

green region = base * height;

what we know:

the base, 28m;

what the sum of the two diameters is, 28;

the length of a single diameter, 14;

what we can assume:

the two semi-circles are equal, as otherwise i cannot see a way to answer this;

the radius of the two semi-circles, 7m as the two diameters = 28, & d/2 = r

what does that mean:

the height is 17m

green region area = 476 m^2

purple region area is = 153.96 m^2

7.) A man is in a boat that is floating 175 feet from the base of a

Delvig [45]

Answer:

The angle of depression between the cliff and the boat is $48.8141^\circ$

Step-by-step explanation:

Given:

Base width of the cliff=175 foot

Height of the cliff= 200 foot= 200 foot

To Find:

The angle of depression between the cliff and the boat=?

Solution:

Angle of Depression

The angle below horizontal that an observer must look to see an object that is lower than the observer.The angle of depression is congruent to the angle of elevation

$tan( y )= \frac{opposite}{adjacent}$
