Answer:
72
Step-by-step explanation:
The pythagorean theorem states that in a right triangle A^2 + B^2 = C^2 where A and B are the two smaller sides and C is the hypotenuse.
Because of this, in this triangle 30^2 + B^2 = 78^2
Which means B^2 = 5184
And B = 72

Answer:
f(-14)=-15
Step-by-step explanation:
What ever is in the parentheses after the letter (in this case it's f) will be the x value since f(x).
So
f(-4)=5(-4)+5
Then solve.
f(-4)=-20+5
f(-4)=-15
-15
Answer:
504 millimeters (or 50.4 cm)
Step-by-step explanation:
- Width of key in student calculator = 14 millimeter (1.4 cm)
- Width of key in demonstration calculator = 2.8 cm
<u><em>Thus, the demonstration calculator's dimensions are </em></u><u><em>twice</em></u><u><em> that of students' (in cm)</em></u>
<u><em /></u>
Also given, student calculator height as 252 millimeters (25.2 cm)
Thus demonstration calculator height will be twice of that = 50.4 cm (or 504 millimeters)
