Answer:
C
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
c² = 4² + 5² = 16 + 25 = 41 ( take the square root of both sides )
c = 
← exact solution → C
Answer:
The height of the projection will be (x - 5) feet.
Step-by-step explanation:
A projector displays an image on a wall. The area (in square feet) of the rectangular projection can be represented by (x² - 8x + 15).
Now to get the width and the height of the rectangular projection we have to factorize the expression (x² - 8x + 15).
Here, (x² - 8x + 15)
= x² - 3x - 5x + 15
= (x- 3)(x - 5)
Now, if the height of the projection is less than its width then, the height of the projection will be (x - 5) feet. (Answer)
<span>Curtis wants to build a model building.
The building height is 180 meter tall.
Now, the model building she wants to build is equals to 1.5cm on each 3.5
meters
Let’s find how tall Curtis’ building model is:
=> 180 meter / 3.5 meter
=> 51.429 meter
Now, let’s multiply this 1 by 1.5 cm
=> 51.429 x 1.5 cm
=> 77.143 centimeters
Round to the nearest tenths
=> 77.1 centimeter tall => the height of Curtis’ Model Building
