Answer:
The football is going to go over the goal post. It will clear the goal post by (16-10) 6 ft
Step-by-step explanation:
y = -0.03x^2 + 1.6x
Let x = 40
We need to determine if y> 10
y = -0.03(40)^2 + 1.6(40)
y = -48+64
y =16
Since 16>10
The football is going to go over the goal post. It will clear the goal post by (16-10) 6 ft
Remember to follow PEMDAS (Parenthesis, Exponents (&roots), Multiplication, Division, Addition, Subtraction)
20-3•6+10²+(6+1)•4
First, solve the parenthesis
6 + 1 = 7
20 - 3 x 6 + 10² + 7 x 4
Next, solve the exponent
10² = 10 x 10 = 100
20 - 3 x 6 + 100 + 7 x 4
Next, solve each multiplication. Remember to bring your sign.
-3 x 6 = -18
7 x 4 = 28
20 - 18 + 100 +28
Simplify
(20 - 18) + (100 + 28)
2 + 128
130
130 is your answer
hope this helps
If we add the 2 equations the terms in x dssappear and we get
2y = 1
so y = 1/2
Substitute in first equtaion:-
1/2 = - 1/2 x + 4
-1/2 x = 1/2 - 4 = - 7/2
x = -7/2 * -2 = 14/2 = 7
answer is (7, 1/2)
Answer:
"half of the 12-inch quesadilla" is larger
Step-by-step explanation:
The "inch size" is the diameter of the circular quesadilla.
The area of circle is given by 
We also know radius is half of diameter.
<u>HALF OF 12-INCH QUESADILLA:</u>
12in diameter = 6 inch radius, the area is:
Half of this is:
<u>ENTIRE 6-INCH QUESADILLA:</u>
6 inch diameter means 6/2 = 3 inch radius
The area of this is:
<u>So, we can say that "half of the 12-inch quesadilla" is larger.</u>
