Answer:
<u><em>The area of the irregular figure is 140 sq. ft.</em></u>
Step-by-step explanation:
<em>Triangle:
</em>
<em>
</em>
<em>16-12=4
</em>
<em>
</em>
<em>6 x 4 = 24
</em>
<em>
</em>
<em>24 x 0.5 = 12
</em>
<em>
</em>
<em>Triangle = 12
</em>
<em>
</em>
<em>Rectangle:
</em>
<em>
</em>
<em>16 x 8
</em>
<em>
</em>
<em>= 128
</em>
<em>
</em>
<em>Rectangle = 128
</em>
<em>
</em>
<em>Total figure:
</em>
<em>
</em>
<em>128+12
</em>
<em>
</em>
<em>= 140
</em>

Okay, let me just make this a little clearer. Hopefully, this is what you meant:
A. y - 8 = -4(x + 4)
B. y - 8 = 4(x + 4)
C. y + 8 = 4(x - 4)
D. y + 8 = -4(x - 4)
--
This can also be written as y2 - y1 = m(x2 - x1).
Your M is your slope.
Both A and D have their m as a negative 4. Because you are looking for a positive slope, immediately cancel those answers.
* note that you could have also put them in a more standard form and discovered m which is the x in bx.
Now, you are looking for an equation that contains (4,-8).
Because it is written as y2-y1, your y's are actually points if you were to find another slope or something. This part is a bit hard to explain, but -8 is only found in the y coordinate place in answer B. Your answer would be B. For more explanation on that, there's this great site called coolmath.com and if you search for finding the equation of two points, it explains it much better on there, but I would not want to plagiarize.
The answer is B.
Answer:
a. 12.8 cm b. 3.125
Step-by-step explanation:
To find any scale drawing use a proportion with one unit of values on the top and the other on the bottom. For example 8cm/5km = x/8km. So you would multiply 8 cm and 8 km and then divide by 5 to get 12.8 cm. For the second question plug in 5m in the numerator and solve for its denominator.
Answer: option C
Step-by-step explanation:
The diagram of the triangle is shown in the attached photo. The triangle is a right angle triangle ABC
Assuming the given angle is #,
Recalling the trigonometric ratio,
tan # = opposite / adjacent
If tan # = 4, it means
opposite / adjacent = 4/1
Therefore, opposite = 4 and adjacent = 1
Applying Pythagoras theorem,
Hypotenuse^2 = opposite ^2 + adjacent ^2
Hypotenuse = AC
Opposite = 4
Adjacent = 1
AC^2 = 4^2 + 1^2 = 17
AC = ± √17
To determine cos #, we would apply another trigonometric ratio,
Cos# = adjacent /hypotenuse
Cos# = 1/±√17
Cos # =-1 /√17 or 1/√17
