(x+1)(x-5)= 2^4=16
x^2 -4x -5 =16
x^2-4x-21=0
x= -3 or 7
but we would choose 7 as the answer as -3 gives negative value at (x+1) and we know that log of negative number is not defined.
Answer:
921.165 feet
Step-by-step explanation:
Ok we are looking for the length of the base.
Now let's take the question and picture it as a triangle, we will find out that it looks like a right angle triangle.
The height= 645 feet
Angle of elevation= 35°
Base is unknown
To find the base
We recall that tan of angle
= opposite/adjacent
In this case
Angle= 35°
Opposite= height= 645
Adjacent= base
Tan 35 = 645/adj
Adj =645/tan 35
Adj =645/0.7002
Adj = 921.165
The base is 921.165 feet
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>

Answer:
The point is in the 4th quadrant.
Explanation:
Given the ordered pair(4, -5), we have that x = 4 and y = -5. Plotting this point, we'll have;
Note that quadrants are labelled in an anti-clockwise direction with the top right portion of the graph as the 1st quadrant. Looking at the plotted point, we can see that it i in the 4th quadrant.
