Answer:
-12°
Step-by-step explanation:
it is negative because it it below zero.
Answer:
<em>5.33 secs</em>
Step-by-step explanation:
Given the equation of the height modeled by the equation/
h(t) = -3.2 + 12.5t + 24.8
The object strikes the ground when the height h(t) is zero
Substituting h(t) = 0 into the expression
h(t) = -3.2t² + 12.5t + 24.8
0 = -3.2t² + 12.5t + 24.8
-3.2t² + 12.5t + 24.8 = 0
Multiply through by minus sign
3.2t² - 12.5t - 24.8 = 0
From the expression a = 3.2, b = -12.5 and c = -24.8
t = -(-12.5)±√(-12.5)²-4(3.2)(-24.8)/2(3.2)
t = 12.5±√156.25+317.44)/6.4
t = 12.5±√473.69/6.42
t = 12.5±21.76/6.42
t = 12.5+21.76/6.42
t = 34.26/6.42
t = 5.33secs
<em>Hence the object strike the ground after 5.33 secs</em>
<u>Answer</u>
= 10
<u>Explanation</u>
EG is one of the diagonals of the rhombus and the other diagonal is FH.
EG = 16 and FH = 12
The diagonals of a rhombus meet at 90°
From this information we can form a right triangle with legs (16/2)=8 and (12/2)=6
The hypotenuse of this triangle is the side of the rhombus.
Using the pythagorean theorem;
L² = 6²+8²
Where L is the length of the rhombus.
L² = 6²+8²
L = √36+64
= √100
= 10
5 - (x + 5) - (2x + 4)
5 - x - 5 - 2x - 4
-3x - 4
Yes it does belong on pizza.
